Answer:
134
Step-by-step explanation:
This equation follows y=mx+b
y = output
x = input
(In this case) 8 = slope
(In this case) 134 = y-intercept
Answer:
r=4
Step-by-step explanation:
15r-6r=36
9r=36
r=36/9
r=4
First, find the different of the two weights
d = 1,200 - 550
d = 650
The different of the weights is 650
Second, to find the percentage, we should compare the difference to the former weight. So we compare 650 to 1,200, then multiply it to 100%
percentage = 650/1,200 × 100%
percentage = (65,000/1,200) %
percentage = 51.17%
percentage = 51%
The percent of increase is 51%
Answer:
.8
Step-by-step explanation:
The ratios have to be the same for the cones to be similar
10 4
----- = ------
2 x
Using cross products
10x = 4*2
10x = 8
Divide by 10
x = 8/10
x = .8
Answer:
Step-by-step explanation:
If ΔABC ~ ΔDEF
Then their sides must be proportional such that:
=> 
Cross Multiplying
=> x * 6 = 8*3
=> 6x = 24
Dividing both sides by 6
=> x = 4
