Step-by-step explanation:

120 children go on a holiday. The ratio of the number of girls to the number of boys is 3:5. On Sunday, all the children either go sailing or go climbing. 16/25 of the boys go climbing. Twice as many girls go sailing as go climbing. Work out how many children go sailing on sunday.

Answers

Answer:

32/50

Step-by-step explanation:

hope this helps if not sorry :)

66 children go sailing on sunday.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

The number of kids go on Holiday =120

The ratio of the number of girls to the number of boys is 3/5.

Number of girls = (3/5)×120 = 72 girls.

Then there are 48 boys

120-72=48

16/25 of the boys go climbing

16/25×48=30

Boys sailing, 48-30 = 18

Twice as many girls go sailing as go climbing

Then 2x+x=72

3x=72

x=24

Therefore 48 girls are sailing and 24 are climbing

Total kids sailing 48+18=66

Hence 66 kids go sailing on sunday.

Find the Dimensions of Rectangle ABCD

Perimeter of ABCD= 80

(Pythagorean Theorem)
Will mark brainliest!

Answers

Answer:

xy + 2x + 2y = (42)(80)

x2 + 80x - 42 = 0

x2 - 42x + 80 = 0

x2 - 21x + 80 = 0

Step-by-step explanation:

The dimensions of the rectangle ABCD is 24 x 16

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the dimensions of the rectangle be represented as L x W

where L and W are the length and width of the rectangle

The perimeter of the rectangle P = 80

Now , measure of side E F of triangle is given by the Pythagoras Theorem

And , E F = √ ( A F )² - ( E A )²

On simplifying the equation , we get

The measure of side E F = √ ( 625 - 400 )

The measure of side E F = √225 = 15

Now ,

The measure of side EC of triangle is given by the Pythagoras Theorem

And , EC = √ ( E F )² - ( C F )²

On simplifying the equation , we get

The measure of side E C = √ ( 15 )² - ( 9 )²

The measure of side E C = √ ( 225 - 91 )

The measure of side E C = √144

The measure of side E C = 12

So , the length of the rectangle B C = E B + B C = 12 + 12

The length of the rectangle B C = 24

The width of the rectangle is A B = W

Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

80 = 2 ( 24 + W )

Divide by 2 on both sides of the equation , we get

24 + W = 40

Subtracting 24 on both sides of the equation , we get

W = 16

Hence , the dimensions of the rectangle is 24 x 16

= 2*3

2*1
=3

Dividing the two fractions is like multiplying the first fraction by value or reciprocal value of first fraction value of SECOND fraction. So find the reciprocal like reversing the numerator and denominator reciprocal of 2/3 is 3

Of the second fraction then multiply the two numerators. Again multiply the two decnominators so the next following step intermediate step canceling by a comma factor 2 gives 3.... in words- two divided by two thirds=three
