A problem states: "There are 5 more girls than boys at the party. There are 27 children at the party in all. How many boys are t

Sever21 [200]

As there is 5 more girls than boys and b is the number of boys, the expression b + 5 represents the number of girls.
total there are 27 childrens
b + (b+5) = 27
b + b + 5 = 27
2b = 27 -5
b =22 / 2
b =11
so the number of boys there are 11 and girls are 11 + 5 = 16
and total is 16 + 11 = 27

Find the area of a circle with diameter 18 yd.

larisa [96]

Answer:

Area of the circle is 254.34 yd²

Step-by-step explanation:

Given:

Diameter of circle = 18 yd
π = 3.14

To Find:

Area of circle.

Solution:

Diameter = 18 yd
Radius = 18/2 = 9 yd

We know that,

$\: \: \: \: \dashrightarrow \: \: \: \: \: {\underline{\boxed{\sf{Area \: of \: circle = \pi r^2}}}} \\ \\$

Substituting the required values,

$\\$

$\: \: \: \: \dashrightarrow \: \: \: \: \: \sf Area_{(circle)} = 3.14 \times {(9)}^{2} \\ \\$

$\: \: \: \: \dashrightarrow \: \: \: \: \: \sf Area_{(circle)} = 3.14 \times 81 \\ \\$

$\: \: \: \: \dashrightarrow { \: \: \: \: \: \sf Area_{(circle)} = 254.34 \: {yd}^{2}} \\ \\$

<u>Hence,</u>

<u>Area of the circle is 254.34 yd²</u>

How to convert percent increase or decrease into a multiplier

ankoles [38]

In case of an increase use this formula
$mutiplier = 1 + \frac{\%}{100}$
So if the percentage of increase of 6%, the multiplier will be
$1 + \frac{6}{100} = 1.06$

In case of a decrease, the formula is mostly the same.
$mutiplier = 1 - \frac{\%}{100}$
So if the percentage of decrease is 6%, the multiplier will be
$1 - \frac{6}{100} = 0.94$
