Answer:
He must read each day=12 pages
Step-by-step explanation:
We are given that
Total number of pages in textbook=120
He has read number of pages=36
Number of days in a week=7
We have to find the number of pages read each day to finish 120 pages in a week.
Number of pages remaining for reading=120-36
Number of pages remaining for reading=84
Now,
Number of pages read each day=[tex]\frac{84}{7}[/tex]
Number of pages read each day=12
Hence, he must read each day=12 pages

If 30% of a number is 15, what is 25% of the number?
Answer:
12.5
Step-by-step explanation:
Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.
Write a number so that the equation will have an infinate number of solutions

What is 65% of 20?
ye
Answer:
13
Step-by-step explanation:
x/20 = 65%/100
20 x 65 = 1300
1300 divided by 100 = 13
Answer:13
First you have to turn the percent into a decimal, and then multiply it by the original number.

x-7=15
Answer:
x = 22
Step-by-step explanation:
x = 7 + 15
x = 22
Answer:
x = 22
Step-by-step explanation:
1x - 7 = 15
1x = 15 + 7
1x = 22 (divide both sides by the first number/1 to get x)
1x/1 = 22/1
x = 22

4.1 graphing linear equations worksheet
(06.04 MC)
Suzie drew the line of best fit on the scatter plot shown.
A graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 15 at increments of 1. The ordered pairs 0, 3 and 1, 3 and 2, 4 and 3, 7 and 4, 6 and 5, 8 and 6, 10 and 7, 10 and 8, 12 and 9, 14 and 10, 15 are shown on the graph. A straight line joins the ordered pairs 0, 3 and 10, 15.
What is the approximate equation of this line of best fit in slope-intercept form?

what is the volume of this box if the volume is scaled down to 1/10? the original volume is 528 and the length is 11 inches the width is 8 inches and the height is 6.
Answer:
Step-by-step explanation:
I assume the box is a rectangular figure
Volume, V=L*W*H
V=11*8*6=528 in^3
528*1/10=52.8 in^3
What is the measure of angle N?
=========================================================
Work Shown:
Apply the law of sines
sin(N)/MO = sin(O)/MN
sin(N)/18 = sin(17)/6
sin(N) = 18*sin(17)/6
sin(N) = 0.87711511416821 ................. which is approximate
N = arcsin(0.87711511416821)
N = 61.296295678111
N = 61 degrees approximately
----------------------
Notes:
Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.The HCF of 36 72 63
The LCM of 8 9 12
LCM of 8,9,12 is 72
HCF of 36 72 63 is 3

Find the slope of the points given, and show work
(2,4) and (-3,3)
Answer: 1/5
Step-by-step explanation:
Let's find the slope between your two points.
(2,4);(−3,3)
(x1,y1)=(2,4)
(x2,y2)=(−3,3)
Use the slope formula:
m=y2−y1/x2−x1
=3−4/−3−2
=−1/−5
=1/5
