<h3>Answer:</h3>
5
<h3>Solution:</h3>
- First, n*7 can be written as 7n.
- Then, 7*5 is equivalent to 35.
- So we have
- 7n=35
- In order to find the value of n, we need to divide both sides by 7:
- n=5

Answer:
2.5 tablespoons of cocoa
Step-by-step explanation:
if 2 cups of milk is originally used then you use 1 well 2 divided by 2 equals 1 and 5 divided by 2 equals 2.5 so you would use 2.5 tablespoons of cocoa
Answer: 3.675 seconds
Step-by-step explanation:
Hi, when the object hits the ground, h=0:
h=−16t^2+48.6t+37.5
0=−16t^2+48.6t+37.5
We have to apply the quadratic formula:
For: ax2+ bx + c
x =[ -b ± √b²-4ac] /2a
Replacing with the values given:
a=-16 ; b=48.6; c=37.5
x =[ -(48.6) ± √(-48.6)²-4(-16)37.5] /2(-16)
x = [ -48.6 ± √ 4,761.96] /-32
x = [ -48.6 ± 69] /-32
Positive:
x = [ -48.6 + 69] /-32 = -0.6375
Negative:
x = [ -48.6 - 69] /-32 = 3.675 seconds (seconds can't be negative)

Answer:
B.The exponent of the solution is –12, the difference of the original exponents.
C.The coefficient of the solution must be greater than or equal to one but less than 10.
D.The quotient is 3.0 × 
Step-by-step explanation:
We are finding the quotient of the expression below in scientific notation

The following conclusions can be drawn
B.The power of 10 in the solution is –12, the difference of the original exponents.
C.The coefficient is 3, which is greater than or equal to one but less than 10.
D.The quotient is 3.0 ×
