How many questions would I have to miss on a 25 question test to get 88% ?

N76 [4]

Let's start with the question, how many questions do you need to get 88%?

so were are looking for
?/25 = 88% and 88% is also 0.88 so we can multiply 25 by 0.88

we get 22

But this doesn't here. the question asks us how many mistakes do you need. you can just subtract 22 from 25

25-22= 3
you need 3 misses to get 88%

X + 4 5/6 = 9 what is x

dmitriy555 [2]

X+29/6=9
(convert mixed fraction to improper)
x=9-29/6
x=25/6 (calculate the difference)
therefore your answer is x=25/6
or x=4 1/6 OR x= 4.16

Multiply or divide as indicated. Leave your answer with no factors in the denominator. p⁻⁴q⁵r⁶/p⁻³qr⁻²

KIM [24]

Answer: $\frac{q^4r^8}{p}$

Step-by-step explanation:

By the Negative exponent rule, we know that:

$a^{-1}=\frac{1}{a}$

By the Quotient of powers property, we know that:

$\frac{a^m}{a^n}=a^{(m-n)$

And by the Product of powers property, we know that:

$(a^m)(a^n)=a^{(m+n)}$

Applying this properties, we get:

$\frac{p^{-4}q^5r^6}{p^{-3}qr^{-2}}=\frac{p^3q^5r^6r^2}{p^4q}=\frac{q^4r^8}{p}$
