Find The Area Of This Circle.Use 3.14 To Approximate .A = Ar214 FtA = [ ? ] Ft?

Answers

Answer 1

Answer:

A =153.86 ft^2

Step-by-step explanation:

First we need to find the radius

f = d/2 = 14/2 = 7

A = pi r^2

A = 3.14 ( 7)^2

A = 3.14 * 49

A =153.86 ft^2

if a man died and left inheritance money$ 3990. As per his will this amount will be distributed in 15:18:17 ratio. Find the share of money each gets?​

Answers

Answer:

The ratios are 15 18 and 17 which total 50

So one person will receive 15/50 = 30 per cent

Another person receives 18/50 = 36 per cent

The third person receives 17/50 = 34 per cent

1st Person  30% of 3,990 = 1,197.00

2nd Person  36% of 3,990 = 1,436.40

3rd Person   34% of 3,990 = 1,356.60

Step-by-step explanation:

Answer:

$1197 : $1436.4 : $1356.6

Step-by-step explanation:

15 + 18 + 17 = 50

3990 / 50 = 79.8

1st person : 79.8 x 15 = 1197

2nd person : 79.8 x 18 = 1436.4

3rd person : 79.8 x 17 = 1356.6

$1197 : $1436.4 : $1356.6

The ordered pairs (6,8), (9, 12), (x, 20), (18, y) represent a proportional relationship. Find the value of X and the value of Y. Select the two correct answers.

Answers

Answer:

x=15 y=24

Step-by-step explanation:

This is because the rule is x goes up 3 y goes up 4

(9,12)->(x,20)

it skips one, so instead of adding 3 we add six

x=15

(15,20)->(18,y)

you follow the rule and 4.

Step-by-step explanation:

To get the percentage, we need to make a straight division, then multiply by 100%

We have this as;

(4.5 * 10^5)/(9 * 10^4) * 100%

Answers

Answer:

You will save $20.

Step-by-step explanation:

IMPORTANT FORMULA: TO CONVERT A NUMBER TO A PERCENT, YOU HAVE TO MULTIPLY BY 100. TO CONVERT A PERCENT TO A NUMBER, YOU HAVE TO DIVIDE BY 100.

1) Some percent of an amount is what?  

Using the formula above, I can conclude that 40% is equal to 40/100=4/10=2/5

2) Translate into an equation.

It is important to keep in mind that we are trying to find 40% of $50 in order to find out how much money will be saved.

In the above step, we already found that 40% = 2/5.

I also know that, in mathematics, the word "of" means multiplication.

Therefore, I am trying to find 40% of $50 is the same as 2/5 * $50.

2/5 * $50 = x    ------ (x represents the money saved)

3) Solve for variable.

$20 = x

4) Write a sentence to answer the question.

You will save $20.
