Answer:
To find a percent of the number, you need to convert the percentage into fractions or decimals. Then, multiply the fraction by the number.
Step-by-step explanation:
1. 60, 90,120,150,180,210,240,270
2. 65/100 x 200/1 = 2 x 65= 130\
3.5/100 x 180/1 = 9
Answer:
D. for the first one, A. for the second (not certain)
Step-by-step explanation:
1. 36/2 (two books every visit) = 18, multiplied by 3 because that's how many often he does to the library (every 3 weeks)
2. 13/2 = w/5 because for every 13 cups of water, there is two cups of cleaner, so for w (unknown amount of water) there would be 5 cups of concontrated cleaner.
Value of an expression 8<span>3
</span>in where 8 is the base number and 3 is the exponent.
To get the answer, simply multiply the base number as many times as the exponent says.
Since the exponent is 3 and base is 8, we need to multiply 8 three times.
=> 8 x 8 x 8
<span>=> 512 </span>
Thus, the value of the given equation 83 is equals to 512
to check if our answer is correct, simply divide 512 by 8 twice.
<span>=> 512 / 8 </span>
=> 62 / 8
<span>=> 8</span>
Step-by-step explanation:
Given
y = - 8 /5 x + 2
Comparing the given equation with y = mx + c
slope (m) = - 8/5
Hope it will help :)
