2r-3.1=1.7 add 3.1
2r=1.7+3.1 divide by 2 to isolate r
2r/2=4.8/2
r=2.4
check
2(2.4)-3.1=1.7
4.8-3.1=1.7
1.7=1.7
4t+3.5=12.5 sub 3.5
4t=12.5-3.5 divide by 4
4t/4=9/4
t=9/4
check
4(9/4)+3.5=12.5
9+3.5=12.5
12.5=12.5
8m-5.5=10.1 add 5.5
8m=10.1+5.5 divide by 8
8m/8=15.6/8
m=1.95
check
8(1.95)-5.5=10.1
15.6-5.5=10.1
10.1=10.1
Answer:
0.70
Step-by-step explanation:
3.50/5 = 0.70
To find the percent change of something you need to set up a proportion.
amount change (original - new) over new number
x over 100
then cross multiply. Example
25 x
----- ------
50 100
25 x 100 = 2500
2500/50 = 50
So the answer is 50%
Answer:
B. 51.6
Step-by-step explanation:
All you have to do is find h when t=2, so just put h=42+28sin(380) into a calculator and you get 51.57656401...
