B you can tell just by look x^2*x^2=x^4
Answer:
254 4/7 or 254.34 ft² (it depends on which method you use.)
Step-by-step explanation:
To find the area of a circle, the formula is πr².
I'll use both 22/7 and 3.14 as pi, so I'll end up with two different answers. Just choose the more reliable one.
22/7 version:
22/7 * 9^2
22/7 * 81/1
1782/7
254 4/7 ft²
3.14 version:
3.14 * 9^2
3.14 * 81
314 - (3.14 * 19)
314 - 62.8 + 3.14
251.2 + 3.14
254.34 ft²
As I said, I ended up with two different answers. You also had said not to round my answer, so the 22/7 version has a mixed number.
A x B x C = 0
Where A and B are integers > 10
Any value multiplied by 0 = 0
Therefore C = 0
Answer:
The same number was not added to both sides.
Step-by-step explanation:
Given:
t - 8 = 65
in the next step it states something wrong, because it should have been this:
t - 8 = 65
add +8 left and right of the = sign.
t - 8 + 8 = 65 + 8
t + 0 = 73
t = 73
So the error made what's that
The same number was not added to both sides.
Since 3 neckties will be out from the
store, so you need to know how much is the cost of 3 ties.
$59.99 x 3 = $179.97 and divide it by two
because the costumer will only pay for 2
$179.97 / 2 = $89.99 is the new price
Mark up = 89.99 – 59.99 = $30.00
% mark up = [(89.99/59.99) -1] * 100
= 50%
