[Right Triangles Only] SOHCAHTOA[Right Triangles Only] cos∅ = adjacent over hypotenuseStep-by-step explanation:
Step 1: Define
We are given a right triangle. We can use trig to find the missing angle.
Step 2: Identify Variables
POV from angle x
Angle = x
Adjacent = 16
Hypotenuse = 27
Step 3: Solve for x
Substitute: cosx° = 16/27Inverse: x° = cos⁻¹(16/27)Evaluate: x = 53.6588°Shawn is a member of a book club. He pays a $50 yearly membership fee and can purchase books through the club for $5 each. His total annual cost is a function of the number of books, b, that he purchases in a year:
C(b) = 5b + 50
What is the total cost if he purchase 17 books in a year?
Answer:
The annual total cost is $135 when he purchases 17 books
Step-by-step explanation:
Given function is:
C(b) = 5b + 50
Here c is the output which is cost and b is the input which is number of books purchased in an year.
In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.
So,
Putting b = 17
[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]
Hence,
The annual total cost is $135 when he purchases 17 books
find the surface area of this cylinder using pie.
Answer:
the surface area of a cylinder:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²
Step-by-step explanation:
Given
r = 10 fth = 15 ftUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi rh+2\pi r^2[/tex]
[tex]A=2\cdot \pi \cdot 15\cdot 10+2\cdot \pi \cdot 15^2[/tex]
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²
Thus, the surface area of a cylinder:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55

The answer to #9 is A is 33 and B is 15
Missing values:

4. 4:10 , 8:20 , 16:40
5. 36:32 18:16
Step-by-step explanation:
#2: The first ratio is shown, which is 5:3. Meaning, that the bottom number (cakes) is multiplied by 5/3 in order to get the top number (pies). We can apply that to the ratio with 12 cakes, 12 multiplied by 5/3 is 20. The next ratio involved 10/3 pies. Since that is the "top" number (see chart), 10/3 need to be multiplied by 3/5 instead of 5/3. By doing that, the number of cakes is 2.
#7: The ratio of milk to ice cream in the mint milkshake is 1.25:4
The ratio of milk to ice cream in the strawberry milkshake is 1.75:5
When the ratios are divided, the quotient for the mint milkshake (0.3125) is LESS than the quotient for the strawberry milkshake (0.35). This means that there is less milk and more ice cream (ratio-wise) in the mint one.

2x -14 = -9 answer for this equation
Answer:the exact form is x=5/2 if its wrong then its probably wrote in a different way
Step-by-step explanation: Move all terms that don't contain
x
to the right side and solve.
Answer:
x= 2.5
Step-by-step explanation:
Simplifying
2x + -14 = -9
Reorder the terms:
-14 + 2x = -9
Solving
-14 + 2x = -9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '14' to each side of the equation.
-14 + 14 + 2x = -9 + 14
Combine like terms: -14 + 14 = 0
0 + 2x = -9 + 14
2x = -9 + 14
Combine like terms: -9 + 14 = 5
2x = 5
Divide each side by '2'.
x = 2.5
Simplifying
x = 2.5

The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure it’s correct answer pls! 20 points for brainliest (also can u tell me how to mark someone brainliest?)
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411

Write the standard form of the line that contains a slope of −1/2 and y-intercept of 1. Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
x + 2y = 4Step-by-step explanation:
Slope-intercept form:
y = mx + bSlope is m = -1/2 and y-intercept is b = 1
The function is:
y = -1/2x + 1Standard form is:
Ax + By = CConverting the function into standard form:
y = -1/2x + 2 ⇒ 2y = - x + 4 ⇒ x + 2y = 4Answer:
Step-by-step explanation:
Slope-intercept form of y = mx + b
Slope is m = -1/2 and y-intercept is b = 1
The function is y = -1/2x + 1
y+1/2x=1
(2y+1x)/2=1
2y+x=2
x+2y=2

Write the following in point-slope form.
Answer:
[tex]\huge\boxed{y-8 = 5(x+1)}[/tex]
Step-by-step explanation:
An equation in point-slope form will be written in the form [tex]y - y_1 = m(x - x_1)[/tex], where a point on the graph is (x1, y1) and the slope is m.
For this equation, all we need to do is substitute the values already given to us, since we know everything needed to write an equation here. All we need is the slope, and one x/y value that's on the graph.
We know the slope is 5, and one point on the graph is (-1, 8), so we can substitute inside the equation.
[tex]y - y_1 = m(x - x_1)[/tex][tex]y - 8 = 5(x - (-1))[/tex] [tex]y-8=5(x+1)[/tex]Therefore, our equation for this line in point-slope form is [tex]y-8=5(x+1)[/tex].

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal. Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
For car A,
Time= 5 hours
Distance = 200 miles.
speed= 200/5
speed= 40 mph
and, In car B
Time= 6 hours
Distance= 480 miles
speed= 480/6
speed= 80 mph
Hence, the speed of car B is twice the speed of car A.
