Answers
x = 100%
20x = 14 . 100
20x = 1400
x = 1400
20
x = 70
S = 20% of 70 is 14.
20 percent of 70 number is 14.
Here we have to find,
The number of which 20 percent is 14
Le the number = x
Now divide 20 by 100
20% = 20/100
= 0.20
Now multiply 0.20 with x we get,
⇒ 0.20x
Now equate it tp 14 we get,
⇒ 0.20x = 14
⇒ x = 14/0.20
= 70
Hence,
The number is 70.

Answer:
The number of students in the seventh grade who would be expected to prefer math over science are:
128
Step-by-step explanation:
Total number of students in seventh grade are: 150 students.
Now he took a sample of 25 students and find that the 85% of the sample prefers math over science.
This means that out of the sample the number of students who prefer maths over science is:
Now, out of the total seventh graders the number of students who prefer math over science is:
which is approximately equal to 128.
Hence, the answer is:
128 students
Option 1 : 25
Option 2 : 85
Option 3 :150
Option 4 :128
Solutions - Convert the percent into decimal and multiply.
85% of 150 = 0.85 * 150
= 127.5 which is rounded to 128

First of all, I think the drawing is confusing. You have to take control of your eyes
until they recognize that the dotted lines are in the back, and the solid lines are in
the front. Then you see that the bottom triangular face of the prism has a base
of 7 and a height of 1.9 . That makes the area of the base (1/2)(b h) = 6.65 m² .
The volume of the whole prism is (area of the triangular face) x 'H' = 59.85 .
H = 59.85 / 6.65 = 9 m³ .
And the part that's enough to make you really steamed up is: You don't need
those measurements of the top face at all . . . the 3m and 5m on top.

1 dime= 0.1 dollars
1 nickel=0.05 dollars
0.1d+0.05n=5.25
d=7n
so,
0.1(7n)+0.05n=5.25
0.7n+0.05n=5.25
0.75n=5.25
n=7
There are 7 nickels and 49 dimes
1 dime = $0.10
n - number of nickels
7n - number of dimes
A equation:
0.05n + 0.1 · 7n = 5.25
0.05n + 0.7n = 5.25
0.75n = 5.25 |divide both sides by 0.75
n = 7
Answer: He have 7 nickels.
