Answer:
C. 3
Step-by-step explanation:
AD is perpendicular to BC, so its slope will be the opposite of the reciprocal of the slope of BC.
The slope of BC can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-1 -2)/(3 -(-6)) = -3/9 = -1/3
Then the slope of AD is ...
-1/(-1/3) = 3
The answer for your problem would be $64.225
there it is your answer
-9n plus 9n is zero 3-8 is -5
(12 + 3) + 32 = 12 + (3 + 32)
Associative property of addition: if you have to sum three or more terms, you can group them as you like.
14(1/14) = 1
Multiplicative inverse: a number multiplied by its inverse is 1
27 + 0 = 27
Identity element of addition. If you sum any number with zero, the result is the number you started with.
11(4y – 9) = 44y - 99
Distributive property of addition: if you have to multiply a whole sum/subtraction by a number, it is the same as multiplying each term in the sum/subtraction by that number.
Answer:
17 hours
Step-by-step explanation:
so first since there are 520 pages we divide it by 124 pages we get 4.19
4.19x4 = 16.77
Rounded is 17
