Divide:

$\frac{5}{7}$ : 3 = $\frac{5}{7}$ x $\frac{1}{3}$ = $\frac{5x1}{7x3}$ = $\frac{5}{21}$

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

Result:

5/7 ÷ 3 = $\frac{5}{21}$

≅ 0.2380952

Find the leg (in inches) of the triangle whose hypotenuse is 10 inches and whose other leg is 3.25 inches. Round to the nearest

alekssr [168]

Answer:

Other Side (B) = 9.45 inches

Step-by-step explanation:

Given:

Hypotenuse = 10 inches

Other Side (A) = 3.25 inches

Find:

Other Side (B) = ?

Computation:

According to Pythagoras theorem:

$Hypotenuse^2= (Perpendicular)^2+(Base)^2\\\\Hypotenuse^2= (A)^2+(B)^2\\\\10^2= (3.25)^2+(B)^2\\\\100=10.5625 +(B)^2\\\\89.4375 = (B)^2\\\\B=\sqrt{89.4375}\\\\B=9.4571$

Other Side (B) = 9.45 inches

A badminton club has 330 members. 240 are adults and the rest are children. Two thirds of the children are boys and the rest are

Margaret [11]

Answer:

The number of boys last year will be 50 boys

Step-by-step explanation:

330 members with 240 adults

The number of children will be;

330-240 = 90

2/3 of 90 are boys

= 2/3 * 90 = 60 boys

Number of girls is 90-60 = 30

Ratio of adults:boys:girls

= 240:60:30

divide through by 30

= 8:2:1

b) A year ago, there were 200 adults but the ratio still remains same

Let the number of girls be x, the number of boys will be 2x

Thus, total number is 200 + x + 2x = 200 + 3x

Total ratio is 8 + 2 + 1 = 11

mathematically;

8/11 * (200 + 3x) = 200

8(200 + 3x) = 11(200)

1600 + 24x = 2200

24x = 2200-1600

24x = 600

x = 600/24

x = 25

So the number of boys will be 25 * 2 = 50
