Answer:
Can you help me then I will help you?
Step-by-step explanation:
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.
So, if you just multiply these you get 9.36*10000, which is 93600.
Answer: 30 mph.
Total speed = S1 + S2
where total speed is
for the average speed goal (60m ph), S1 is the speed for the first mile (30 mph)
and S2 is for speed for the second mile which is unknown. To solve, simply subtract
S1 from total speed.

Answer:
-1/4
Step-by-step explanation:
y2 - y1 / x2 - x1
-9 - (-6) / 3 - (-9)
-3/12
= -1/4
Given : The Number of Correct Answers = 30
Given : Total Number of Questions = 40
⇒ The Number of Wrong Answers = (40 - 30) = 10
The Ratio of the Number of Correct Answers to Number of Wrong Answers is :
(1st Blank)
The Ratio of the Number of Correct Answers to Total Number of Questions is :
If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :
