Answer:

61.2 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h ( $b_{1}$ + $b_{2}$ )

Substitute in given values

A = $\frac{1}{2}$ × 4 × (13.8 + 16.8 ) = 2 × 30.6 = 61.2 cm²

Serenity picked 75% of the apples of a tree in her backyard. If she picked 30 apples, how many apples were on the tree to begin

Stells [14]

Given:

Serenity picked 75% of the apples of a tree in her backyard.

She picked 30 apples.

To find:

The number of apples on the tree in the beginning.

Solution:

Let x be the number of apples on the tree in the beginning.

Serenity picked 75% of the apples of a tree in her backyard.

Number of apples picked = 75% of x

= $\dfrac{75}{100}x$

= $\dfrac{3}{4}x$

She picked 30 apples.

$\dfrac{3}{4}x=30$

Multiply both sides by 4.

$3x=4\times 30$

$3x=120$

Divide both sides by 3.

$x=\dfrac{120}{3}$

$x=40$

Therefore, the number of apples on the tree in the beginning is 40.

I am pretty sure the answer is 3.5.

(2+x)5=11

(2+x)=11/5

(2+x)= 5.5

x= 5.5-2

x= 3.5
