Write the equation of the line that is perpendicular to y = 3x - r and that has the same y - intercept .
WILL MARK BRAINLIEST
Answer:
y= -(1/3)x -r
Step-by-step explanation:
a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.
In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.
The problem states the line has the same y-intercept so it has to still be -r.
So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

A softball team has 12 girls on it. The coach needs to arrange 9 girls for the batting order. If the lineup is selected at random, what is the probability that you will be the lead-off batter (the first person to bat)?
Answer: P = 1/12 = 0.083
Step-by-step explanation:
Out of the 12 girls, there will be only one that is the lead-off batter.
we can assume that this is the first being selected at random, then the probability that you will be the lead-off batter, is equal to the quotient between 1 (the outcome where you are selected) and 12 (the total number of outcomes)
Then the probability is:
P = 1/12 = 0.083
The fact that there will be an arrange of only 9 girls does not affect the probability of you getting the position of the lead-off batter.

A rocket booster initially applies 10,000 N of force to a 1,000.0 kg rocket causing it to accelerate at 10.0 m/s2. Ten minutes later, the rocket booster is released and it falls through the atmosphere.
The mass of the rocket is now 760.0 kg and its acceleration is 7.0 m/s2. How much force is now being applied to the rocket?
Answer:
5320 Newtons
Step-by-step explanation:
mass time acceleration so 760 kg times 7 secs
The force that should be applied to the rocket is 5,320N.
Given that,
The mass of the rocket is now 760.0 kg and its acceleration is 7.0 [tex]m/s^2.[/tex]Based on the above information, the calculation is as follows:
[tex]= 760 \times 7.0[/tex]
= 5,320N

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?
Answer:
The calories you will consume are 1134 calories
Step-by-step explanation:
Let us solve the problem
∵ A recipe for blueberry muffins states that it yields 12 muffins, with 270
calories per muffin
→ Find the total calories of the 12 muffins
∴ The total calories of them = 12 × 270
∴ The total calories of them = 3240 calories
∵ You instead decide to make mini-muffins, and the recipe yields 20
mini-muffins
→ That means the same amount of calories are in 20 mini-muffins, to find
the calories of each one divide the total amount of calories by 20
∵ The calories per mini-muffin = 3240 ÷ 20
∴ The calories per mini-muffin = 162 calories
∵ You will eat 7 mini-muffins
∴ The calories you consume = 7 × 162
∴ The calories you will consume = 1134 calories

16.0 grams of food contain 130 calories. How many grams of food would you need in order to consume 2150 calories?
Answer:
you can set up a proportion
16.0/130 = x/2150
by cross multiplying you get
130x = 34400
divide by 130 and get
x-264.62

After 12:00, the number of people in Mal-Wart
grows steadily until 6:00p.m. If the equation
y= 228 + 58x represents the number of people in
the store x hours after 12:00, how many people
were in the store at 12:00?
Answer:
228
Step-by-step explanation:
substitute 0 for x
A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.
A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 20x + 4.
Answer:
Range[4,24,44,64,84,104,124]
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs
20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in
pounds can be represented by f x( ) = 20x + 4.
What is the range of the function for this situation?
The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6
The given function is
f(x) = 20x + 4 =
f(0) = 20(0) + 4
= 4
f(6) = 20(6) + 4
= 124
Which means the range is within 4 and 124.
But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24
Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)

find the gcf and use it to reduce 36/63
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
The greatest common factor of 36 and 63 is 9.
Thus, [tex]\frac{36}{63}[/tex] = [tex]\frac{4}{7}[/tex] since (36 ÷ 9 = 4) and (63 ÷ 9 = 7).
Answer:
4/ 7
Step-by-step explanation:
you list the factors of each number so factors of 36 are 1 2 3 4 6 9 12 18 36 and factors of 63 are 1 , 3 , 7 , 9 , 21 and 63 as the highest common factor in each number is 9 you do 36 ÷ 9 = 4 which will be the numerator and 63÷ 9 = 7 which will be the denominator so the simplest form of 36/63 is 4/7

Multiply using the distributive property (X+4)(X^2+6x-3)
Answer:
x^3 + 10x^2 + 21x - 12
Step-by-step explanation:
(x + 4)(x^2 + 6x - 3)
you can separate to make it easier for u
x(x^2 + 6x - 3) + 4(x^2 + 6x - 3), this is optional u don't have to do this part
x^3 + 6x^2 - 3x + 4x^2 + 24x - 12
add like terms together
x^3 + 10x^2 + 21x - 12

The slope is the same.
Solve for x:
(-3/2)x-9=-27
- 24
-12
11
12
i love these kind of questions :D
okay so lets write our problem down 1st:
(-3÷2)x-9=27
okay so you take one of your answers lets do A 1st and put is as x like this:
(-3÷2)-24x(-9)=27 now solve:
(think of PEMDAS)
P = perenthesis
E = exponents (which you dont have in this problem)
M = multiply
D = divide
A = add
S = subtract
do perenthesis 1st which would be (-3÷2)
(-1.5)-24x(-9)
now multiply 24x(-9)
(-1.5)-216 = (-214.5) does it equal -24 (which was what you plugged in for x)
no it doesnt so A cant be your answer. now do it for the rest of your answers :D
