Answer:
<em>The new mixture is 49% peanuts.</em>
Step-by-step explanation:
The first batch of 9 lb of mixed nuts contains 55% peanuts. This means the quantity of peanut is:
9*55/100=4.95 lb
The second batch of 6 lb of mixed nuts contains 40% peanuts. This means the quantity of peanut is:
6*40/100=2.4 lb
The total quantity of peanut in the mix is
4.95 lb + 2.4 lb =7.35 lb
There are 9 lb + 6 lb = 15 lb of mix. Thus, the percent of peanut in the mix is:
7.35 / 15 * 100 = 49%
The new mixture is 49% peanuts.
Answer:
7-x
Step-by-step explanation:
49 - x^2 is a perfect square so
it factors to :(7+x)(7-x)
since there is a negative in 49 - x^2, it would make sense that the answer would be a negative to get that negative answer in the first place (negative times a positive equals a negative)
Forgive me for my lame explanation :')
The equivalent expression to 11^-7 × 11^5 is one over eleven raised to the second power. option A
Exponential
11^-7 × 11^5
= 11^(-7+5)
= 11^(-2)
= 1 / 11²
Options:
one over eleven raised to the second power
(1/11)²
one over eleven raised to the power of negative two
(1/11)^-2
11^2
−11^2
Therefore, the equivalent expression to 11^-7 × 11^5 is one over eleven raised to the second power.
