Answer:

about 15

Step-by-step explanation:

14^2 = 196

15^2 = 225

so √196 = 14, √225 = 15

and 221 is close to 225, so it's about 15 and the exact value would also be between 14 and 15

Simplest form of ratio 24:36:60​
kumpel [21]

Answer:

2:3:5

Step-by-step explanation:

24:36:60

<u>1) Find the greatest common factor</u>

24 ⇒ 1, 2, 3, 4, 6, 8, 12, 24

36 ⇒ 1, 2, 3, 4, 6, 9, 12, 18, 36

60 ⇒ 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Therefore, the greatest common factor is 12.

<u>2) Divide all values by 12</u>

24 ÷ 12 = 2

36 ÷ 12 = 3

60 ÷ 12 = 5

Therefore, the simplified form of the ratio is 2:3:5.

I hope this helps!

1. In the figure, m DE = 106 degrees and m BC = 62 degrees. The diagram is not to scale.
k0ka [10]
For question 1, the formula for that is m1= 1/2(a-b). 106 being A and 62 being B. You should get m1=.5*(106-62) which equals B.22

Please help me! Will give points and mark brainliest answer. I have been stuck on this for a while too. Will give 30 points.
garri49 [273]

Answers:

1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.

1B. Idon't know how to graph it here sorry.

1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.

1D. I just did

If 1m = 3.3 ft, how many cubic feet is the Kuroshio Sea tank? Volume is 9,450. Show your calculations!
Naddika [18.5K]

Answer:

339604.65 cubic feet

Step-by-step explanation:

We are given that 1 m is equal to 3.3 ft.

1 m = 3.3 ft

This means that if we find the volume of a cube of 1 m, we have its volume as:

1^3 = 1 m^3

In the same way, the volume of a cube of 3.3 ft (1 m) is:

3.3^3 = 35.937 ft^3

This means that:

1m^3 = 35.937 ft^3

The Kuroshio sea tank has volume of 9450 m^3. Its volume in cubic feet is therefore:

1m^3 = 35.937 ft^3\\\\9450 m^3 = 9450 * 35.937 = 339604.65 ft^3

The volume of the tank is 339604.65 cubic feet.
