Answer:

finding area formula of a circle:

πr^2 (pie r (radius) squared)

Pie could equal: 22/7 or 3.14

Use 3.14 most likely,

Given information

Radius is: 12

(needs to be squared)

12 x 12 = 144

144 x 3.14 <------ (pie or π) = 452.16

452.16 rounded to the nearest hundredth is:

452.16 miles. (doesn't have a thousandths place so we can't really round but we should assume the number by itself)

patriot [66]

Answer:

Let me take 2,3,3 be 2x, 3x, 3x

Colin = 2x

Natasha = 3x

Angad = 3x

The equation forms to find out the value of x

2x + 3x + 3x = 48

=> 8x = 48

=> x = 48/8

=> x = 6

So share of Colin = 2x = £(2×6) = £12

Share of Natasha = 3x = £(3×6) = £18

share of Angad = 3x = £(3×6) = £18

For proof

£12 + £18 + £18 = £48

Hope it helps

How do you increase 429 Grams by 31%

Papessa [141]

If you want to increase something by 31% then...

100%+31%=131% or 1.31

you multiply it by 131% or 1.31. So for 429 grams...

429*1.31=561.99grams

If you increase 429 by 31%, you get 561.99 grams

Answer=561.99 grams

The mean of the values in a data set is c. If each of the values in the data set were multiplied by 6, what would be the mean of

oksian1 [2.3K]

Answer:

Mean of the data would be 6c

Step-by-step explanation:

<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.

In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c

Let us consider that original values in the data set are x, y and z. Their mean would be:

$Mean=\frac{x+y+z}{3}$

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

$Mean=\frac{6x+6y+6z}{3}\\Mean=\frac{6(x+y+z)}{3}\\Mean=6\times\frac{x+y+z}{3}\\Mean=6c$

We can see from above that the new mean is 6 multiplied to the original mean.

Therefore, the answer to this question is 6c.
