Mathematics
2 answers:
Komok [63]2 years ago

Answer:

x/90 = 13/130(you can simplify this btw)

x90       x90

X = 9

Make both of them ratios

X to 90 and pick another random one 13 to 130.

Make sure to make them equal to eachother then just solve for x.

You can also compare it to 9 to 90

It would still work:

x/90 = 9/90

x90      x90

X = 9, x would also equal 9

Answer:

x = 9

Step-by-step explanation:

Assuming the rectangles are similar

13           x

------ = ---------

130         90

Using cross products

13*90 = 130*x

Divide each side by 130

13*90/130 = x

x = 9

HELP PLEASE!!

<span>Volume of the Sphere V = 4/3pi x r^3 So when diameter d = 3 inches => r = 1.5 inches volume of the sphere = 4.188 x r^3 = 4.188 x 1.5^3 = 14.14 in So when diameter d = 8 inches => r = 4 inches volume of the sphere = 4.188 x r^3 = 4.188 x 4^3 = 268.03 in So when diameter d = 9 inches => r = 4.5 inches volume of the sphere = 4.188 x r^3 = 4.188 x 4.5^3 = 381.63 in value for option (a) is 3 x 14.14 = 42.42 inches value for option (b) is 268.03 inches value for option (c) is 381.63 / 2 = 190.815 inches So the correct option would be (b)</span>

a mug is 2/7 full. The mug contains 1/3 of a cup of water. Find the capacity of the mug. Write the answer as a fraction or mixed
Ahat [919]

Answer:

7/6 cups

Step-by-step explanation:

Given the following information :

Mug is 2/7 full

Amount of water in the mug = 1/3 cup

Assume the full capacity of the mug = m

Then the current capacity of water in mug = (2/7) of m = (2/7)m

Current capacity of water in mug is equivalent to 1/3 cup of water

Hence,

(2/7)m = 1/3

2m/7 = 1/3

Cross multiply

(2m * 3) = 7 * 1

6m = 7

m = 7/6

m = 1 1/6 cups
