Answer:
The pythagorean theorem states that a² + b² = c².

We have a = 10 and c = 20.

100 + b² = 400

Subtract 100 from each side.

b² = 300

Get the square root of 300.

It could be expressed as b ≈ 17.321, or could stay in radical form as.

Hope this helps!

**Answer:**

**Step-by-step explanation:**

Area of circle = πr²

= 3.14 * 12 * 12

= 452.16 sq. cm

Are = radius squared times pie so 12*12 = 144 so 144 times pi 3.14*144 = 452.16 is your answer

.22 because 2 is greater than zero

The answer is **0.22**, because you always look at the tenths place when you're trying to find the greater number in decimal. If the number in tenths place is greater then that's your answer.

So first you need to add the two years together to get 91,800,000 from there you can start to turn it into scientific notations. First start out by putting an imaginary decimal point at the end so you have 91,800,000. From there you need to move the decimal next to the 9 so 7 spots to the left. This means that when you are converting back from SN you would go 7 spots to the right. Therefore when you write this in SN you will have 10 to the power of positive 7.Now that you have the number and the exponent you just put them together and you have 9.18 x 10^7 . I hope this helped and if you have any questions about how I got this answer feel free to message me.

Just add 41,300,000 to 50,500,000. That is 91,300,000.00 tons. Scientific Notation just moves the decimal point to the beginning. So it would be 9.13*10^7

Rebecca has a 50 pence coin, a 20 pence coin, and a 5 pence coin.

Jeremy has three 50 pence coins.

Jeremy has three 50 pence coins.

To answer the problem, the coins of Janice must be a penny, dime, and a nickel which total up to $0.16, while Jeremy's coins are three dimes and two pennies totaling $0.32

The problem can be approached by considering the different coins you have available and their values. In the U.S, these are penny ($0.01), nickel ($0.05), dime ($0.10), quarter ($0.25), half dollar ($0.50), and dollar ($1.00). Because Jeremy's coins are all the same and twice Jane's total, this limits us to lower value coins.

Let's start with Jane. She can't have a quarter because Jeremy doesn’t have $0.50 coins. If she had a dime, Jeremy would need two dimes but we know all his coins are the same so this isn't possible. This means Jane must have a penny ($0.01), a nickel ($0.05) and a dime ($0.10) for a total of $0.16. Therefore, Jeremy, whose total is twice Jane's, must have $0.32 which can be achieved by having three dimes ($0.10 x 3 = $0.30) and two pennies ($0.01 x 2 = $0.02).

20:36 ratio of 20 to 36

25:81 ratio of 25 to 81

10:14 ratio of 10 to 14

14:18

**Answer:**

20:36

**Step-by-step explanation:**

5:9

multiply both parts of the ratio by 4

5 x 4 = 20

9 x 4 = 36

So 20:36 is equivalent to 5:9

If i am correct, the answer should be 13608.

To find out how much Ada saved a month, we would need to add 179 and 145, that equals 324. Then we would need to multiply that by 12 because there are 12 months in a year. We would get 3888. Then we would need to multiply that by 3, since there are 3 years. We would get 11664. Then we would need to multiply 324 and 6 for 324 dollars a month. That gives us 1944. Then we add 1944 and 11664, we get 13608. :)

Ada would save $**13,608** in three and half year (42 months)

- Amount saved by Bao a month = 179
- What Ada saved = what Bao saved + $145

To calculate what Ada saved:

- Let X represents = Bao
- Y represents = Ada

Therefore,

X = 179

Y = X + $145

Therefore we have:

Y = 179 + 145

Y = 324

Therefore, Ada saved 324 each month.

To determine how much Ada saved in 3 years and a half, we have to first convert years into months

- 3 years is same as 36 months
- Half a year is same as 6 months

Therefore, we have:

36 + 6

= 42 months

Therefore, how much Ada saved in 42 months = what Ada saved each month multiply Y= (324) by the total number of months (42)

Therefore we have:

Y = 324 x 42

Y = $13,608

So, Ada saved $13,608 in three and half years (42 months)
