Property of zero as an exponent
Answer:
x=3
Step-by-step explanation:
<h3>
Answer: 76%</h3>
Any number out of 100 can be quickly converted to percent form by just tacking on the percent sign. This is because "percent" is "per one hundred". Think of 100 cents in a dollar which may help you remember.
So 76/100 = 76%
For this case we have the following variables:
f: The amount of fabric in yards
n: The number of shirts
The equation modeling the problem is given by:
For 12 yards of fabric we have:

From here, we clear the value of n.
We have then:
Answer:
16 shirts were sewn
Answer:
-11 < x < 7
(first option listed)
Step-by-step explanation:
we know that x² + 4x < 77
first, we should rewrite our expression in standard
x² + 4x - 77 < 0
factor {find two numbers that multiply to c (77) and add to b (4) }
(x - 7) (x + 11) < 0
set both roots to 0:
x - 7 < 0
+ 7 + 7
x < 7
x + 11 < 0
x > -11
so, x will be < 7 and > -11
which can be expressed as
-11 < x < 7
So, -11 < x < 7
