Answer:
37,400
Step-by-step explanation:
Whatever the number 10 is being squared by, you just move the decimal right if it is a positive number. In this case, it is 10 to the 4th power.
If you move the decimal in 3.74 four times to the right, you will get 37,400.

Answer:
Last year there were 550 bison in the heard and this year it is 10% larger.
10% is also 10/100 or 0.10
To find 10% of the heard last year
550 x.0.10 = 55. To find the number in the heard this year add 550 (last year) + 55 (10% growth) = 605 or,
to find how many there are now last years heard size was 100% of the heard or 1.00. To find any percent more add it to 1.00 and multiply by the starting amount.
550 x 1.10 = 605
For the second example.
If there are 550 bison in the heard this year, and this year was a decrease of 10% from last year we can express last year's number like this.
550 = (x - (x * 0.10)) simplify;
550 = 1x - 0.10x
550 = 0.90x
Divide both sides by 0.90
x = 611.11 but it's hard to have 0.11 of a bison so realistically 611 bison last year. Subtract 10% or 61 and you indeed have 550 this year.
Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...
x² + 6x - 24 = 0
Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132
x = -6 +/- √132 x' = -3 + √33
<span> -------------- /
2 \
x'' = - 3 - </span>√33
The correct answer is the letter D
I hope this help =)
