Answer:
45 minutes.
Step-by-step explanation:
d = 40 - 1/5m
When d = 31 we have:
31 = 40 - 1/5 m
1/5 m = 40 - 31 = 9
m = 9*5
= 45 minutes answer.
Answer:
2x
Step-by-step explanation:
Factor both terms given to simplest terms:
8x = 2 * 2 * 2 * x
22xy = 2 * 11 * x * y
Note that in each case, there is the factor of 2 & x that is shared by both. These are what is used to find the Greatest Common Factor. Multiply both terms together:
2 * x = 2x
2x is your GCF.

Answer:
The answer to your question is: 6 units
Step-by-step explanation:
Data
A (-4, 0)
B (-3,1)
C (0,-2)
D (-1,-3)
Formula
d = √((x2 - x1)² + (y2 - y1)²)
Process
dAB = √((x2 - x1)² + (y2 - y1)²) dAC = √((0 + 4)² + (-2 + 0)²)
= √((-3 + 4)² + (1 - 0)²) dAC = √((4)² + (-2)²)
= √((1)² + (1)²) dAC = √(16 + 4)
= √1 + 1 dAC = √20
dAB = √2 = dCD
dAD = √((-1 + 4)² + (-3 - 0)²)
dAD = √((3)² + (-3)²)
dAD = √9 + 9
dAD = √18 = dBC
reactangle's area = base x height = √18 x √2 = √18 x 2 = √36
= 6 units
Answer:
$163.85
Step-by-step explanation:
Since the cost of the couch is $113.00 then this is the original 100% price. To find a 45% mark up then find 145%. Remember 100+45 = 145. To find the price set up a proportion with these values:
![\frac{x}{113}=\frac{145}{100}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B113%7D%3D%5Cfrac%7B145%7D%7B100%7D)
Solve for the price by cross multiplying numerator with denominator.
x(100) = 113(145)
100x = 16385
x= 163.85
