Answer:
the base of the ramp is 31 inches long.
Step-by-step explanation:
c = a/sin(α)
= 33.48514
b = √c2 - a2
= √33.4851373155042 - 122
= √977.25442103816
= 31.26107
Let x=the number of $1 bills she has, and let y=the number of $5 she has. From the information given, we can say:
x+5y=40
x+y=12
When you subtract the first equation from the second equation, you get:
x+5y-x-y=40-12
4y=28
y=7
Therefore, Hermione has 7 $5 bills in her purse.
Answer: 94 degrees Farenheight
Step-by-step explanation:
6x4 would equal 24+70 equals 94
Answer:
Step-by-step explanation:
First you add 4 on both sides
X^2=0
Then you take square on both sides
X=+- the square root of 4
Simplify that
X=plus or minus 2
The answer can be either -2 or +2 (which is just 2)
