Alja [10]

Answer:

No

Step-by-step explanation:

To calculate how much fence is needed we need to calculate the perimeter NOT area.

P = 2L+2W

P =2(6.75)+2(4 2/3)

P = 13.5 + 9 1/3

P = 22 5/6

Because she only has 22 yards she does not have enough to go all the way around.

There are some people in a cinema.
Elan Coil [88]

Answer:

Adults = 510

Step-by-step explanation:

Given

Children = \frac{3}{5}

Girls:Boys = 2 : 7

Girls = 170

Required

Determine the number of adults

First, we need to calculate the number of children

Girls:Boys = 2 : 7

Given that: Girls = 170

Substitute 170 for Girls in Girls:Boys = 2 : 7

170 : Boys = 2 : 7

Convert to fraction

\frac{170}{Boys} = \frac{2}{7}

Cross Multiply

Boys * 2 = 170 * 7

Divide both sides by 2

Boys = \frac{170 * 7}{2}

Boys = \frac{1190}{2}

Boys = 595

So, the number of children are:

Children = Boys + Girls

Children = 595 + 170

Children = 765

Next, we calculate the number of people in the cinema.

Children = \frac{3}{5} * People

Substitute 765 for Children

765 = \frac{3}{5} * People

Make People the subject.

People = \frac{765 * 5}{3}

People = \frac{3825}{3}

People = 1275

If 3/5 are children, then 2/5 are adults.

So:

Adults = \frac{2}{5} * 1275

Adults = \frac{2* 1275}{5}

Adults = \frac{2550}{5}

Adults = 510
