Answer:

height = 56.7

Step-by-step explanation:

Using sohcahtoa method:

$\frac{opposite}{hypotenuse} =sin(x)$

$\frac{height}{86} =sin(43)$

$height= sin(43)*86$

$height=58.652$

$height=56.7$

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit

weeeeeb [17]

Answer:

$Change = \$8.82$

Step-by-step explanation:

Given

$Basketball = \$25.57$

$Air\ Pump = \$15.61$

$Amount = \$50$

Required

Determine the change received

First, we need to calculate the total amount spent

$Total = \$25.57 + \$15.61$

$Total = \$41.18$

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

$Change = Amount - Total$

$Change = \$50 - \$41.18$

$Change = \$8.82$

<em>Hence, the change is $8.82</em>

Stephon has a square brick patio. He wants to reduce the width by 4 feet and increase the length by 4 feet.

alekssr [168]

Answer: The expressions for the length and width of the new patio are

$\ell=x+4,~~w=x-4.$

And the area of the new patio is 384 sq. feet.

Step-by-step explanation: Given that Stephen has a square brick patio. He wants to reduce the width by 4 feet and increase the length by 4 feet.

The length of one side of the square patio is represented by x.

We are to write the expressions for the length and width of the new patio and then to find the area of the new patio if the original patio measures 20 feet by 20 feet.

Since Stephen wants to reduce width of the patio by 4 feet, so the width of the new patio will be

$w=(x-4)~\textup{feet}.$

The length of the patio is increased by 4 feet, so the length of the new patio will be

$\ell=(x+4)~\textup{feet}.$

Now, if the original patio measures 20 feet by 20 feet, then we must have

$w=x-4=20-4=16~\textup{feet}$

and

$\ell=x+4=20+4=24~\textup{feet}.$

Therefore, the area of the new patio is given by

$A_n=\ell \times w=24\times16=384~\textup{sq. feet}.$

Thus, the expressions for the length and width of the new patio are

$\ell=x+4,~~w=x-4.$

And the area of the new patio is 384 sq. feet.
