In a race, Car #1 went an average of 165 miles per hour for x hours before dropping out. Car #2 went an average of 175 miles per
Akimi4 [234]
When you think about it. It's actually quite easy.
The number are the amount of miles, and the variables are the amount of hours. So we would just have to multiply them. So, by putting the number together we would be able to multiply them once we have the numbers for the variables. Since we dont have them, we can just make the inequality. It says that car 1 traveled at LEAST that of car 2. Showing that car 1 may have traveled farther. SOOOOO........ the inequality should look like this:

165x <span>≥ 175y</span>

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?
dedylja [7]

Answer:

V=2

Step-by-step explanation:

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?

P=8/V

Inverse variation is expressed as

y=k/x

Where,

k= constant.

From the question,

P=8/V

Where,

8=constant

What is the value of V when p=4

P=8/V

Make V the subject of the formula

pV=8

V=8/p

Substitute the value of p

V=8/4

V=2

A circle has diameter of 11cm
dlinn [17]

Since length of diagonal (  Diagonal= 9.9cm ) is less than diameter of circle ( 11 cm ) , Therefore , the square will fit inside the circle without touching the edge of the circle.

<u>Step-by-step explanation:</u>

Here we have , A circle has diameter of 11 cm  A square has side length of 7 cm . Use Pythagoras’ Theorem to show that the square will fit inside the circle without touching the edge of the circle . Let's find out:

We know the concept that for any square to fit inside the circle without touching the edge of circle  , diagonal of square must be less than diameter of circle  . Let's find out length of diagonal by using Pythagoras Theorem :

Hypotenuse ^2 = Perpendicular^2+Base^2

For a square , Perpendicular = base = side

⇒ Diagonal^2 = 2(side)^2

⇒ Diagonal= \sqrt{2}(side)

⇒ Diagonal= \sqrt{2}(7)

⇒ Diagonal= 9.9cm

Since length of diagonal (  Diagonal= 9.9cm ) is less than diameter of circle ( 11 cm ) , Therefore , the square will fit inside the circle without ruching the edge of the circle.

The photo shows a small coin. The scale from the actual coin to the photo is
Aleks [24]

8mm to 2cm is the same as 8mm to 20mm

8 : 20 simplifies to 2 : 5

3.25cm ÷ 5 = 0.65cm

0.65 x 2 = 1.3cm

Your answer is 1.3cm
