The inequality x ≤ 3 indicates how many different bicycle outfits she can purchase.
How do you write inequality and solve it?She has $560 to spend at a bike shop on new accessories and clothing for riding.
For $425.05. she spends on a brand-new bicycle.
She spends $15.19 for each of four bicycle reflectors and $15.79 on a pair of cycling gloves.
She intends to use all or part of the remaining funds to purchase new bicycle clothing at $29.20 each.
The disparity that can be used to calculate how many garments she can purchase for her budget is as follows:
let
x = the number of garments
Therefore,
425.05 + 15.19(4) + 15.79 + 29.20x ≤ 560
425.05 + 60.76 + 15.79 + 29.20x ≤ 560
29.20x ≤ 560 - 425.05 - 60.76 - 15.79
29.20x ≤ 58.4
Divide the difference between the two sides by 29.20.
x ≤ 58.4 / 19.20
x ≤ 3.04166666667

Answer: X = 12, Y = 60°
Step-by-step explanation:
We are given a parallelogram. We know one degree measure, and one given side. To find X, create an equation, x + 3 = 15. Solve. X = 12. Since this is a parallelogram, Y must equal 60°, since parallelograms have two sets of equal degree measures.

Write a function rule P(m) to represent Evelyn’s profit per mask so that she can always find what her profits will be for any amount of masks (m) she sells.
By answering the presented question, we may conclude that Evelyn will equation need to sell roughly 281 masks in order to cover her initial project expenditures and begin generating a profit.
What is equation?A math equation is a technique that links two assertions and denotes equivalence using the equals sign (=). In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For example, in the equation 3x + 5 = 14, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to understand the link between the two phrases written on either side of a letter. The logo and the programmed are usually interchangeable. As an example, 2x - 4 equals 2.
Initially, we must determine the entire cost of producing and transporting one mask:
Total cost per mask = $1.25 plus $2.15 for delivery = $3.40
Profit per mask is selling price minus total cost per mask, which equals $5 - $3.40 = $1.60.
As a result, Evelyn will profit $1.60 for each mask she sells. We may use the following calculation to calculate how many masks she needs to sell to recoup her $450 initial project costs:
Total beginning project expenditures / profit per mask = number of masks to sell
Total number of masks to be sold = $450 / $1.60 per mask = 281 masks
Evelyn will need to sell roughly 281 masks in order to cover her initial project expenditures and begin generating a profit.

Philip and Laura want to build a pool in their backyard. The length and width of the pool can be represented by the equation f(x)=(x-3)(5x+2) feet. What is the area of Philip and Laura’s pool? You must show your work and include your units.
Answer:
5 by 2, 13 by 4, and 6 by 6.
The pool at Philip and Laura's home is therefore 5 x 2 x 13 x 6 square feet in size.
Step-by-step explanation:
We must multiply the pool's length by its breadth to determine its area. The formula f(x) = (x-3)(5x+2) yields the length and width, so:
Size equals (x-3) feet
Size is (5x+2) feet wide.
Length times Width equals (x-3) times (5x+2) square feet.
Increasing the brackets results in:
Area: 5 by 2, 13 by 4, and 6 by 6.
The pool at Philip and Laura's home is therefore 5 x 2 x 13 x 6 square feet in size.

Find the unpaid balance, new interest, and purchasing power on the credit card after the minimum monthly payment is made. The interest charge for unpaid balances is 18% per year.
Credit Card Balance = $5000
Credit Limit = $5000
Minimum Payment = $125.00
The credit card's outstanding amount is [tex]4875[/tex], the new interest rate is [tex]75[/tex], as well as the buying power is [tex]50[/tex] after paying the required minimum payment of [tex]125[/tex].
What does the word "interest" mean?The urge to become interested with something, give it your whole attention, and learn more about it My entire life, astronomy has captivated me. He never seems to be concerned about his children.
Why is there an interest?You pay the interest on almost any loans and bank debt of money. The proportion of the loan balance used by lenders to compute interest. Clients who lend money can earn interest
We determine the monthly interest charge,
Interest charge = (1.5% per month) [tex]*[/tex] (5000 unpaid balance)
Interest charge [tex]= 75[/tex]
The new overdue debt is obtained by deducting the minimum monthly payment from the original unpaid balance:
Unpaid balance [tex]= 5000 - 125[/tex]
Unpaid balance [tex]= 4875[/tex]
we add the interest charge to the new unpaid balance to get the new balance:
New balance [tex]= 4875 + 75[/tex]
New balance [tex]= 4950[/tex]
Lastly, we may determine the purchasing power by deducting the new balance from the credit limit:
Purchasing power [tex]= 5000 - 4950[/tex]
Purchasing power [tex]= 50[/tex]
Therefore the unpaid balance on the credit card is [tex]4875[/tex], the new interest charge is [tex]75[/tex], and the purchasing power is [tex]50[/tex].

What is a rectangle?
A quadrilateral with parallel sides that are equivalent to one another and four equal vertices is known as a rectangle. It is also known as an equiangular rectangle for this reason.
A rectangle is given with parallel sides equal.
Two opposite angles are 90°.
A diagonal is drawn.
The given information describes a rectangle, which is a special case of a parallelogram with all angles equal to 90°.
In a rectangle, the diagonals are congruent and bisect each other.
Therefore, the correct option is (HL) hypotenuse-leg, which is a special case of the congruence rule for right triangles.
If we consider the right triangle formed by one of the diagonals and one of the sides of the rectangle, we can see that we have a right triangle with hypotenuse equal to the diagonal and leg equal to one of the sides of the rectangle.
Since the diagonals are congruent and the sides of the rectangle are equal, we have a case of HL congruence.
Option (a) AAS (angle-angle-side) and option (c) SSS (side-side-side) do not apply to this situation since we only have information about one side and one diagonal of the rectangle.
Option (d) "Not equal and congruent" is not a valid answer choice as congruent objects, by definition, must be equal.

# of rolls per trial 20 50 100
# of times a 3 was rolled 8 18 30
Julia made a die for a game. It had 5 faces, labeled 1-5. Because of the shape of the die, it was biased in favor of rolling a 3. We do not know the amount of bias. She experimented to extimate how likely it was for a 3 to be rolled and her results are in the above table.
In question #1, you found the best estimate of the probability of rolling a 3. Using that estimate, how many times would a 3 be rolled after 200 rolls?
We can conclude after answering the provided question that We can estimate that a 3 would be rolled probability 71 times after 200 rolls if we round off to the nearest integer.
What is probability?Probability is a way of measuring of how likely an event is to occur. It is represented by a number respectively 0 and 1, with 0 representing an unlikely event and 1 representing an unavoidable event. Switching a valid coin and coin flips has such a probability of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probability theory is a branch of mathematics that studies random events instead than their properties. It is applied in many fields, including facts and figures, finance, science, and construction.
Based on the information provided, the estimated probability of rolling a 3 can be calculated as follows:
8/20 = 0.4 for 20 rolls
18/50 = 0.36 for 50 rolls
For 100 rolls: 30/100 = 0.3
We can take the average of these values to get the best estimate:
(0.4 + 0.36+ 0.3) / 3 = 0.3533
As a result, the best estimate of the likelihood of rolling a 3 is 0.3533.
We can estimate the number of times a 3 would be rolled after 200 rolls using this probability as:
The number of times a 3 would be rolled equals the probability of rolling a 3 multiplied by the number of rolls.
= 0.3533 x 200
= 70.66
We can estimate that a 3 would be rolled approximately 71 times after 200 rolls if we round off to the nearest integer.

2065 Old Q.No. 10 A sum of money put out a compound interest increased by Rs. 180 at the end first year and Rs. 188 10 at the end of second year. Find the rate percent and [5] the sum. Ans: 4.5% p.a., Rs. 4,000
If a sum of money put out a compound interest increased by Rs. 180 at the end first year and Rs. 188 10 at the end of second year. The rate is 4.5% and the sum is $4,000.
How to find the rate?Let the sum of money be x.
After the first year, the amount becomes x+180.
After the second year, the amount becomes (x+180)+188.10 = x+368.10.
Let the rate of interest be r, expressed as a decimal.
Then, using the formula for compound interest, we have:
(x+180) = x(1+r)
(x+368.10) = (x+180)(1+r) = x(1+r)² + 180(1+r)
Subtracting the first equation from the second, we get:
188.10 = x(1+r)² - x(1+r) + 180(1+r)
8.10 = x(r+r²) + 180r
Simplifying this equation, we get a quadratic in r:
r² + r(180/x) - 8.1/x = 0
Using the quadratic formula, we can solve for r:
r = [-180/x ± sqrt((180/x)² + 4(8.1/x))]/2
r = [-180/x ± sqrt((32400/x²) + (32.4/x))]/2
r = (-90/x) ± sqrt((8100/x²) + (8.1/x))
Since r must be positive (since the amount increased), we take the positive root:
r = (-90/x) + sqrt((8100/x²) + (8.1/x))
Substituting the given values of the increase and solving for x, we get:
180 = x[(1+(-90/x)+sqrt((8100/x²)+(8.1/x))) - 1]
180 = x(-90/x + sqrt((8100/x²)+(8.1/x)))
180 = -90 + xsqrt((8100 + 8.1x)/x³)
270 = xsqrt((8100 + 8.1x)/x³)
72900 + 729. x = 729. x²
x² - x(100.1) + 720000 = 0
(x-400)(x-1800) = 0
x = 400 or x = 1800
Since x cannot be negative, we take x = 400.
To find the rate of interest, we use the first equation:
x+180 = x(1+r)
180 = x*r
r = 180/x
r = 180/ 400
r = 0.45 = 4.5% per annum.
Therefore, the sum of money is Rs. 4,000.

F(x)= 2ax^2 + bx + 3 has a relative extremum at the point (-1,2)
At the relative extremum
a = 1/2 and b = 2What is a relative extremum?
A relative extremum is a relative minimum or maximum of a function.
Since the function F(x) = 2ax² + bx + 3 has a relative extremum at the point (-1,2). This implies that dF(x)/dx = 0 at the extremum.
So, F(x) = 2ax² + bx + 3
dF(x)/dx = d(2ax² + bx + 3)/dx
= d2ax²/dx + dbx/dx + d3/dx
= 4ax + b
dF(x)/dx = 0
⇒ 4ax + b = 0
⇒b = -4ax at x = -1
b = -4a(-1)
= 4a
Since the function F(x) = 2ax² + bx + 3 has a relative extremum at the point (-1,2), we have that
F(-1) = 2a(-1)² + b(-1) + 3
= 2a - b + 3
F(-1) = 2
⇒2a - b + 3 = 2
⇒2a - b = 2 - 3
2a - b = -1
Now, b = 4a
So, substituting b into the equation, we have that
2a - b = -1
2a - 4a = -1
-2a = -1
a = -1/-2
a = 1/2
So, b = 4a
= 4(1/2)
= 2
So,
a = 1/2 and b = 2Learn more about relative extremum here:

Which graph shows the solution set of the inequality 2x10x+16/x-3>0
So the correct option is (d), for that we have know little bit about graph because graph is helpful to represent points.
What is Graph?A diagram that depicts the relationship between two variables, usually (generally) measured along opposite axes in a pair, is used.
We have that means given,
[tex]\frac{x^{2} +10x+16}{x-3} > 0[/tex]
[tex]\frac{(x+2)(x+8)}{x-3} > 0[/tex]
So,
(a). (x +2) >0
(x +8) > 0
[tex](x - 3) > 0 \implies x > 3[/tex]
(b). (x +2) < 0
(x +8) < 0
[tex](x - 3) > 0 \implies No\ Solution[/tex]
(c). (x +2) > 0
(x +8) < 0
[tex](x - 3) < 0 \implies No \ Solution[/tex]
(d). (x +2) < 0
(x +8) > 0
[tex](x - 3) < 0 \implies -8 < x < -2.[/tex]
[tex]So, -8 < x < -2 \ or\ x > 3[/tex]
