7013/10
Step-by-step explanation:
first, count the decimal to the right
as you can tell, we can only do it once so therefore we get 10
we then multiply 701.3/1 both sides with 10
then we get out answer 7013/10
Answer:
Associative property
Step-by-step explanation:
This property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends (or the multiplicands).
eg. a+(b+c) is same as (a+b)+c
Hello from MrBillDoesMath
Answer: 6.2 feet
Discussion:
The ladder and the wall form a right triangle. The length of the ladder, 20 in this case, is the hypotenuse of the triangle. Let "x" be the distance between the foot of the ladder and the building. Then from trigonometry,
cos (@) = length of adjacent side/ hypotenuse
or in our case
cos(72) = x / 20 => (multiply both sides by 20)
20 * cos(72) = x.
Using a calculator this becomes
20 * ( .3090) = 6.18 feet (approx) or 6.2 feet , rounded to the nearest foot.
Thank you,

1/4 of 1360....." of " means multiply
1/4 * 1360 = 1360/4 = 340
The exponential equation
is equivalent to the log form equation
The base of the log is the same as the base of the exponent. The 8 inside the log argument is the right hand side of the original equation. The goal with logs is to isolate the exponent, so that's why 3 is on its own side
