Answer:
c
Step-by-step explanation:
C. This is the correct answer because the wage rises by $2, which is 2/20=10% increase. Next year the increase percent is 2.20/22=10%. That's a constant percent increase
Answer:
-3, -1, 1
Step-by-step explanation:
The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.
From inspection of the graph, the curve intercepts the x-axis at
x = -3, x = -1 and x = 1
<span>First we add 2m to both sides, leaving 7m + 72 = 52 (since -2m + 2m cancels out). Next, we subtract 72 from both sides, bringing us to 7m = -20. Solving for m, we get -20/7. Since this is not one of the listed options, it is possible that the original poster has made a typographical error.</span>
Answer:
2) A, 3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total? 4) A, C, E. 5) 4
Step-by-step explanation:
2) Elena already walked 12 miles, she then walks another 1/4 of those 12 miles. The answer is A.
3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total?
4) to find the answers figure out how much they multiply one number by and multiply the other number by that amount. For example, the ratio 2:5 can be the same as 4:10 because you are multiplying the original ratio by 2 to get the new ratio.
5) The diameter of a circle is the length of one side to another. to find the length of the outer edge you need to find the circumference. To find the circumference of a circle you must use 
*Diameter. To find the answer we must use 180/D. Since pi can not be defined we will use 3.14 as a rough estimation. 3.14*12=37.68. 180/37.68=4.777070064. Since it doesn't make much sense to do .8 of a invitation then we must round down. The answer is 4.
Answer:
Let the angle be x.
Its complement is 90°-x° and its supplement is 180°- x.
If 90°-x = (1/2)(180°-x) then 180°- 2x = 180° -x => 180°-180° = 2x-x => x= 0°
Hence the statement is true only for 0°
