Answer:

If you meant [80 + (8*4) ]/2, then [80 + (8*4) ]/2=56

or if you meant 80 + [ 8*4 / 2], then 80 + [ 8*4 / 2] = 96

Step-by-step explanation:

Evalute the expression. 80 + (8x4) divided by 2

so do you mean

the whole expression 80 + (8x4) is over 2 ?

If so then:

evaluate 8x4 = 8 * 4 = 32.

so we have 80 + (8x4) is over 2 = (80 + 32)/2 = 112/2 = 56

If you meant 80 + [ 8*4 / 2]

then 80 + [ 8*4 / 2] = 80 + 8*2 = 80 + 16 = 96

The length of a rectangular garden is 9ft longer than its width . The gardens perimeter is 182 feet . Find the length of the gar

CaHeK987 [17]

Let, width = x, length = x+9

perimeter = 2(l+w)

=2(x+x+9)=182

=2(2x+9)=182

=4x+18 = 182

=4x = 164

=x = 41

Length would be (x+9) = 41+9 = 50 ft

The formula for the area of a circle is A equals xr2 this formula allows you to find the area of a circle if you know the radius

iVinArrow [24]

Answer:

The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$

Step-by-step explanation:

Given as :

The formula for the area of circle = $\pi$ × radius²

I.e A = $\pi$ × radius²

Now If we know radius then

Area calculated as A= $\pi$ × radius²

If we know Diameter then

Area calculated as $\pi$ × ( $\dfrac{\textrm Diameter}{2}$ )²

Or, A = $\pi$ × ( $\dfrac{\textrm D}{2}$ )²

I,e A = $\frac{\pi D^{2} }{4}$

If we know the circumference then

∵ circumference = c = 2 × $\pi$ × radius

or, c = 2 × $\pi$ × r

from here we calculate radius

I.e r = $\frac{c}{2\pi }$

And So , Area ( A ) = $\pi$ × radius²

I.e A = $\pi$ × ( $\frac{c}{2\pi }$ )²

Or, A = $\frac{c^{2} }{4\pi }$

Hence The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$ Answer

A salesperson earns a commission of $391 for selling $2300 in merchandise.Find the commission rate. Write your answer as a perce

aalyn [17]

The salesperson earns a commission of $391

The total amount of merchandise that he sold is $2300

The commission rate is given by

$r=\frac{\text{commission amount}}{\text{ sold amount}}$ $r=\frac{\$391}{\$2300}=0.17$

To convert the rate into percentage, multiply with 100%

$r=0.17\cdot100=17\%$

Therefore, the commission rate is 17%.

EXPLAIN the difference between surface area and volume in your own words

MAXImum [283]

Surface area is the sum of the areas of all the faces of the solid figure. Finding surface area of solid figure is like finding how much wrapping paper that is required to cover the solid; it is the area of the outside faces of a box. ... Volume is the amount of space inside of the solid figure.
