Marcia started work at 7.32 and finished work at 3.43. In total she worked 8 hours and 11 minutes.
Convert the 11 minutes into decimal form:
11 minutes / 60 minutes in an hour = 0.18 (rounded)
Multiply her hourly rate by her hours worked:
8.18*6.75 = $55.125 (you can round this up or down).
Answer:
Step-by-step explanation:
500+7500=8000
150x50=7500
8000 books were sold over the course of 50 days
Answer:
160 in^2.
Step-by-step explanation:
I guess this is a prism with 6 faces so the surface area is:
2 * 8 * 4 + 2 * 8*4 + 2*4*4
= 64 + 64 + 32
= 160 in^2.
Answer:
Linear approximation is given by: 
Step-by-step explanation:
We are given the following information in the question:
Number of citations: 5 7.5 10 15 20
Outputs Residuals: 3 6 10 5 6
We have to find the linear approximation of the data that passes through the points (5, 3) and (20, 6).
Linear approximation is given by:
The equation of line is given by:
where, 
is the point through which the line passes.
The equation of line is:
The above equation is the required linear approximation.
Let the two integers be x and x+1
(x+1)^2-x^2=21
x^2+2x+1-x^2=21
2x+1=21
2x=20
x=10
then x=10, x+1
10+1=11
the two integers are 10, 11
