(B. looks like it may also be one).
Answer:
You write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
Step-by-step explanation:
so for example, .005 would be 5x10^-2 and 500 would be 5x10^2
Answer:
180-142=38 for the acute angle next to the entry
90+38=128
180-128=52
a=52
Answer:
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Step-by-step explanation:
1. Information given to us to solve the problem:
Marc's age today = 0
Marc's grandmother age today = 56
2. In how many years will Marc's grandmother be 5 times as Marc will be then?
x = Number of years when Marc's grandmother age will be 5 times as Marc will be then
Let's solve for x, this way:
5 times Marc age in x years = Marc's grandmother age in x years
5 (0 + x) = 56 + x
5x = 56 + x
5x - x = 56 (Subtracting x at both sides)
4x = 56
x = 56/4
<u>x = 14</u>
Let's prove that x = 14 is correct:
5 (0 + 14) = 56 + 14
70 = 70
We proved that x = 14 is correct
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
