<em>According to exponents of exponent rule, we need to distribute whole exponent over exponents of inside terms of parenthesis.</em>
We are given whole exponent 2 there.
We can apply exponents of exponent rule.
Therefore,
Therefore, 
<h3>Correct option is second option
</h3>
Answer:
2:5
Step-by-step explanation:
The ratio of a dimension on Figure B to the corresponding dimension on Figure A is ...
4:10 = 8.6:21.5 = 10:25 = 2:5 or 1:2.5
___
In such problems, it isn't clear if the desired answer is the ratio of two integers or if it is 1 : (something). We have expressed it both ways, so you can use the answer that matches your requirement.
Answer:
88 inches
Step-by-step explanation:
The given bicycle has a tyre that is 28 inches in diameter.
How far the bicycle moves forward each time the wheel goes around is the circumference of the bicycle tyre.
This is calculated using the formula:
C =\pi \: d
We substitute the diameter and
\pi = \frac{22}{7}
C = \frac{22}{7} \times 28
This simplifies to
C =22 \times 4
88 \: inches
546 - 525 = 21
21 is 4% of 525.
Lisa gained a 4% pay increase.
. The amount of TIME spent driving (which depends on the SPEED of the car) is 5 hours. means time(speed) = 5. TIME and SPEED are your key words and 5 is the key number.
