Answer:

B

Step-by-step explanation:

All circles are similar and therefore proportional. C/C' is the ratio of Circle C to Circle C'. Since it is 0.75, this means that C is 75% of C'. We know that radius of C will also be 75% of the radiuc of C'. We can the radius because we know the diameter of Circle C is 6. The radius is therefore 3. 3 is 75% of 4. So r/r' or 3/4=0.75. r/ must be 4.

Write an expressionNick has x toy race cars. This is one third of what Bob has. How many toy race cars does Bob have?
natita [175]

Given:

Nick has x toy race cars. This is one-third of what Bob has.

So, the number of Nick toys = one-third of what Bob has.

Let the Bob has y toys

So, we can write the following expression:

x=\frac{1}{3}y

Solve for y, multiply both sides by (3):

y=3x

So, the answer will be:

Bob has (3x) toy race cars.

9 and 11 need help<br> Mark brainlist
zvonat [6]

I will do 9 only. You can do 11.

Question 9

sin(60) = x/8

sin(60)(8) = x

4•sqrt{3} = x

x^2 + y^2 = 8^2

(4•sqrt{3})^2 + y^2 = 64

16(3) + y^2 = 64

48 + y^2 = 64

y^2 = 64 - 48

y^2 = 16

sqrt{y^2} = sqrt{16}

y = 4

Do 11 the same way.
