First write 18% as a decimal by moving the decimal point two places to the left to get <em>.</em>18.
The word "of" means multiply, so we have (.18)(75) which is 13<em>.</em>5.
The answer would be 10.19m. If you want to round it of to a less precise measurement it would be 10 m. That is rounding of the decimal value to the ones place. the rule of rounding of is form 6 t0 9 it would add 1 to the nearest place value next to it and 0 - 5 will not.
Answer:
x= -4
Step-by-step explanation:
so you add 2 to both sides because on one side it's -2, and remember you need to get x by itself, then you solve for x and get the answer which is -4, here are the steps:
x- 2 = -6
x-2+2= -6 + 2
x - 0 = -4
x = -4
<u>Answer:</u>
It would be 81
<u>Step-by-step explanation:</u>
is the same as 9 times 9. And 9 times 9 is 81.
Answer:
28
Step-by-step explanation:
You want the smaller of the two factors of 896 that have the ratio 8:7.
<h3>Setup</h3>
Let x represent the smaller of the two factors (the one we want to find). Then the larger factor is (8/7)x, and their product is ...
x(8/7)x = 896
(8/7)x² = 896
<h3>Solution</h3>
Multiplying by the inverse of the coefficient of x², we have ...
x² = (7/8)(896) = 784
x = √784 = 28 . . . . . . . . take square root
The smaller of the two numbers is 28.

<em>Additional comment</em>
The larger is (8/7)(28) = 32.
