An easy way to find the precentage to to tuen the precentage to a decimal, in this case 20%=0.2, now multiply 35 by 0.2
35x0.2=7!
So 20% of 35 is 7$!
Another way to solve is to take 10% of 35, which you can find by just movig over the decimal (35-$3.50) now just add it together! 3.5+3.5=7$!!
Hope I helped!
Answer:
1 meter to centimeters: 1 meter x 100
1 meter to kilometers: 1 meter ÷ 1,000
Step-by-step explanation:
Answer:
W = 6t + 90
Step-by-step explanation:
Given :
Starting weight = intercept = 90 kg
Weight gained after 8 months = 138 kg
Using the slope intercept relation ;
We can obtain the rate of change, slope ;
y = mt + c
m = slope ; t = time after t months ; c = intercept
y = weight gained after 8 months
138 = 8m + 90
138 - 90 = 8m
48 = 8m
m = 48 / 8
m = 6
Hence, slope intercept equation equals :
W = 6t + 90
Answer:
The beryllium atom; 1.99 times larger.
Step-by-step explanation:
The beryllium atom is 0.000000000112 meters, while the nitrogen atom is 0.000000000056 meters. So, the beryllium atom is larger than the other.
(1.12 * 10^-10) / (5.6 * 10^-11)
= (1.112 / 5.6) * (10^-10 + 11)
= 0.1985714286 * 10
= 1.985714286 * 10^0
So, the beryllium atom is about 1.99 times larger than the other.

Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Number of markers could be represented by following division problem:
Total length of the road ÷ each marker space =
<h3>a) 6 3/4 ÷ 1/8.</h3>
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
On simplifying, we get
27 × 2 = 54.
<h3>c) There would be total number of 54 markers of lengths (1/8) of a mile.</h3>
