Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r

Aleks [24]

Answer:

The expression that represents her gross pay each day will be: $(5h+8)$ dollars.

Step-by-step explanation:

Suppose, Harriet's gross pay each day $= x$

So, her total gross pay for 7 work days $=7*x= 7x$

Given that, her gross pay at the end of 7 work days is $(35h + 56)$ dollars.

So, the equation will be.......

$7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8$

Thus, the expression that represents her gross pay each day will be: $(5h+8)$ dollars.

You want to install a 2 yd wide walk around a circular swimming pool. The diameter of the pool is 23 yd. What is the area of the

GrogVix [38]

Answer:

157 square yards.

Step-by-step explanation:

Given:

Width of walk around a circular swimming pool = 2 yard

The diameter of the pool = 23 yard

Question asked:

What is the area of the walk ?

Solution:

To find area of walk, we will first calculate area of the pool and then combined area of pool and walk then after we will subtract the area of pool from combined area.

The diameter of the pool = 23 yard

Radius of the pool = $\frac{diameter }{2}=\frac{23}{2} =11.5\ yard$

$Area\ of\ circle=\pi r^{2}$

$=3.14\times(11.5)^{2} \\=3.14\times11.5\times11.5=415.265\ square\ yard$

As width of walk around a circular swimming pool is 2 yard :

New radius will be = 11.5 + 2 = 13.5 yard

$Combined\ area =\pi r^{2} \\$

$=3.14\times13.5\times13.5=572.265\ square\ yard$

Now, area of the walk = Combined area of pool and walk - Area of the pool

= 572.265 - 415.265

= 157 square yards

Therefore, area of the walk is 157 square yards.
