Answer:

$15000-750x$

Step-by-step explanation:

Holly is trying to save $25,000 to put a down payment on a condominium. She starts with $10,000 saved and saves an additional $750 each month,

So, if she starts with $10000, she has only $15000 to go.

This is reducing by $750 per month.

Let the number of months it takes to reach her goal be x.

So, the equation that represents how far Holly is from her goal of reaching $25,000 is : $15000-750x$

Given a rectangular pyramid and a rectangular prism that have the same base and same height, how do their volumes compare? If th

Luden [163]

We know that
volume of a rectangular prism =B*h------> equation 1
where
B is the area of the base
h is the height

volume of a rectangular pyramid=(1/3)*B*h-----> equation 2
where
B is the area of the base
h is the height

substitute equation 1 in equation 2
volume of a rectangular pyramid=(1/3)*volume of a rectangular prism

the answer part a) is
volume of a rectangular pyramid=(1/3)*volume of a rectangular prism

Part b) If the pyramid was full of water, how much of the prism would it fill up?

the answer part b) is
If the pyramid was filled with water, the prism would only fill 1/3 of its volume

Part c) Name another pair of three-dimensional objects that have a relationship similar to this

cones and cylinders

volume of a cylinder =B*h------> equation 1
where
B is the area of the base
h is the height 

volume of a cone=(1/3)*B*h-----> equation 2
where
B is the area of the base
h is the height

substitute equation 1 in equation 2
volume of a cone=(1/3)*volume of a cylinder

At eagle bay it cost $12 per hour to rent a Canoe Nate and his friends rented a canoe for 4 hours and paid $68. Write and solve

stich3 [128]

The cost to rent the canoe for 7 hours is $ 104

Solution:

At eagle bay it cost $12 per hour to rent a Canoe

Nate and his friends rented a canoe for 4 hours and paid $68

Let "x" be the number of hours rented

We can solve use the point slope equation

$y-y_1 = m(x-x_1)$

Where, "m" is the rate of change

$(x_1, y_1)$ is the sample point

From given,

m = 12

$(x_1, y_1) = (4, 68)$

Therefore,

$y - 68 = 12(x-4)$

$y - 68 = 12x -48\\\\y = 12x -48+68\\\\y = 12x + 20$

Thus the linear equation is found

Here, "y" represents the amount paid for "x" hours

Find the cost to rent the canoe for 7 hours

Substitute x = 7 in linear equation

y = 12(7) + 20

y = 84 + 20

y = 104

Thus cost to rent the canoe for 7 hours is $ 104
