I think is is:
7/20=35/100=0.35=35%
Hope I'm not wrong!
Hope this helps! :D
Answer:
y = 2x + 21
Step-by-step explanation:
Step 1: Write out known variables
y = mx + b
m = 2
y = 2x + b
Step 2: Find <em>b</em>
9 = 2(-6) + b
9 = -12 + b
b = 21
Step 3: Rewrite linear equation
y = 2x + 21
Fastest method for calculating what percent of 900 is 18
Assume the unknown value is 'Y', and 18 of 900 can be written as:
Y =
18
900
By multiplying both numerator and denominator by 100 we will get:
Y =
18
900
x
100
100
=
2
100
Y = 2%
Answer: 2 percent of 900 is 18
If you want to use a calculator, simply enter 18÷900x100 and you will get your answer which is 2
Note that
10² = 100
0.08² = 0.0064
and
101.6064 = 100 + 1.6 + 0.0064
It also happens that
1.6 = 2 • 10 • 0.08
which means
101.6064 = 100 + 1.6 + 0.0064
101.6064 = 10² + 2 • 10 • 0.08 + 0.08²
101.6064 = (10 + 0.08)²
101.6064 = 10.08²
which means
√101.6064 = 10.08
which, to one decimal place, is approximately 10.1.
The answer is D) 0.36. The most preferred gum flavor is spearmint, which had 90 votes, and the total amount of students surveyed is 250. Then, do 90/250, which is 0.36 to find the answer. Hope this helps. By the way, took the test and got it right.
