Answer:
B. 
Step-by-step explanation:
We all suck at math... just lmk if you need more help...
7 + 1.25t = 43.25 <== ur equation
1.25t = 43.25 - 7
1.25t = 36.25
t = 36.25 / 1.25
t = 29 <== he was jumping for 29 minutes
If you would like to know what percent is 27.30 of 36.40, you can calculate this using the following steps:
x% of 36.40 = 27.30
x/100 * 36.40 = 27.30
x/100 = 27.30/36.40
x = 27.30/36.40 * 100
x = 75
To check: 75% * 36.40 = 75/100 * 36.40 = 27.30
The correct result is 75%.
The solution of the equation x2+7x is 0, -7 using the quadratic formula.
Step-by-step explanation:
x2 + 7x = 0
-b ± √
b2 - 4(ac)/ 2a
substitution,
a = 1, b = 7, c = 0
= -7 ± √(7)2 - 4(1 x 0) / 2 x 1
= - 7
± 7 / 2
x = 0 , -7
70 x 100 = 7,000
Therefore, 70 hundred is equal to 7 thousands.
