Celeste and Dora both offer guitar lessons. Celeste charges an initial fee of $5.00, and an hourly rate of $7.25. Dora has an in

itial fee of $10.25, and an hourly rate of $6.50. At how many hours of instruction will the cost for each instructor be the same?
Which equation represents the scenario?
(7.25h + 5) + (6.5h + 10.25)
(5h + 7.25) + (10.25h + 6.5)
5h + 7.25 = 10.25h + 6.5
7.25h + 5 = 6.5h + 10.25

The equation for the celeste is,

Celeste=5+7.25h

Here , h is the number  of hour

now,the equation for the Dora is ,

Dora= 10.25+6.5h

For the same cost, after h hours

5+7.25h=10.25+6.5h

The last option is correct

Answer: hypotenuse=16

Step-by-step explanation:

First, you need to know the concept of a special triangle 30-60-90. The corresponding ratio of each side is 1-√3-2. Basically means, the shortest side is 1, the other longer leg is √3, the hypotenuse is 2. You can also refer to the attachment below

For this question, given the shortest side is 8, and asked to find the hypotenuse.

Short side:hypotenuse=1:2

8:hypotenuse=1:2

hypotenuse=16

Hope this helps!! :)

Rachel has a box in the shape of a prism with a square base. The capacity of the box is 150 cubic inches. The height of the box
Alex777 [14]

Answer:

Step-by-step explanation:

What do we know about that prism?

It's a rectangular prism with a square base.

Height: y (from question)

base length: x (from question)

base width: x (from question, since it's a square base).

Total volume: 150 cu inches

The question lacks a relationship between x and y the "is __ times", but we can see from the answer choices that they all show a constant relationship:

y = 1.5 x  

The volume of a prism is obtained by  multiplying the lengths of its 3 dimensions: V = length * width * height.  In our case, we then have

150 = x * x *  y

then we replace y by its x-expressed equivalent:

150 = x * x * (1.5x) = 1.5x³

then we isolate x³ by dividing each side by 1.5

x³ = 100, we do the cubic root on each side

x = 4.64

So, answer is D. x = 4.6 and y = 6.9

If you you 4.64 * 4.64 * 6.96 = you get 149.8, which is very close to 150.
