You'd have to get 112 out of 140 in order to get an 80% right on the dot
Answer:
1/1296
Step-by-step explanation:
P( 5) = number of 5's over total numbers possible
= 1/6
P( 5,5,5,5) = 1/6 * 1/6 * 1/6* 1/6
=1/1296
Answer:
A. Lara added 3 cups of blue paint to every cup of red paint.
B. 1/3 because 3*1/3 is 1
C. $8 because 6*8=48
Step-by-step explanation:
Answer:
complementary angles
Step-by-step explanation:
That square drawn by the vertex of those angles indicates that the angle formed by the vertical ray pointing up and the horizontal ray pointing right is a right angle. A right angle measures 90 degrees. The measures of the angles measuring x and 71 add up to 90 degrees.
Definition:
Complementary angles are two angles whose measures have a sum of 90 degrees.
The angles measuring x and 71 are complementary angles.
L:w=5:7
l/w=5/7
cross multiply
7l=5w
(7/5)l=w
P=2(L+W)
P=72
72=2(L+W)
divide both sides by 2
36=L+W
W=(7/5)L
36=L+7/5L
36=12/5L
times both sides by 5
180=12L
divide both sides by 12
15=L
W=(7/5)L
W=(7/5)15
W=21
length=15ft
width=21ft
dimeitions are 15 by 21ft
