Answer:
The correct answer is A.
Step-by-step explanation:
You do not need to perform any operations to derive the correct answer from the choices provided. As you can see from the choices, the 3/4th power of 81 will turn out to be 27 (
). The 3/4th power of d to the power of 24 is d to the power of 18 (
).
With that being said, the most important thing to take note of is the <u><em>negative</em></u><em> </em><u><em>symbol</em></u> of the power. A negative power turns a value into its reciprocal. In this case, both the 81 and the d to the power of 24 will both go into the denominator (since the two are encompassed in a set of parentheses together) — you apply what was previously mentioned regarding what the power of 3/4 will do to 81 times d to the power of 24 — and your answer is choice A!
The answer is 24. If you divide 84 by 2 then you will get 24
Answer:
4.5 miles
Step-by-step explanation:
We can use a ratio to solve
3 miles x miles
--------------- = ----------------
80 minutes 120 minutes
Using cross products
3 * 120 = 80x
Divide each side by 80
360/80 = 80x/80
4.5 =x
70% = 0.7
0.7 of 200 = 0.7*200
= 140
So, 70% of 200 is 140
Answer:
x=y-3
Step-by-step explanation:
okay, so first, we have to understand what the words mean.
PRODUCT: means the answer to a multiplication question
DECREASED: taken away or to make smaller
AND: addition or add
We can use X for "product" and Y for "a number"
now we can write it out:
x=y+5-3
OR
y+5-3=x
