Answer:
35% of the sixth grade is in the chess club
Step-by-step explanation:
if there are 100 students consider that as 100%
20 is a fifth of 100
20 x 5 =100
since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.
7 x 5 = 35
35/100 = 35%

What is the question?
Step-by-step explanation:
Answer:
90+.30=1.20 per mile
if he goes 30 miles he would pay 120$
90x30=120
idk if this is right but I hope so
Answer:
Option A (7×3) + 1/2(7×6)
Step-by-step explanation:
Divide this shape into a square and a triangle
For area of square the formula is
Area = A = L ×W
From shape of square
7 seven boxes are yellow so L=7 and width W=3
A = 7 × 3
For triangle formula is
A = (1/2)bh
A = (1/2)(7×6)
Add them
A = (7×3) + 1/2(7×6)
By definition, the area is given by:
A = w * l
Where,
w: width
l: length
We have two expressions for the length:
L = 14\\L = 5 + 3c
Since the length is the same, we equate both expressions:
5 + 3c = 14
From here, we clear the value of c:
3c = 14 - 5\\3c = 9
c = \frac{9}{3}\\c = 3
Then, we have that the width is given by:
W = 6c-8
Substituting the value of c we have:
W = 6 (3) -8\\W = 18-8\\W = 10
Finally, the area is given by:
A = w * l\\A = 10 * 14\\A = 140 ft ^ 2
Answer:
he should order 140 square feet
