3/4 as a number = 0.75
So 1.75 x d = 14
14/1.75 = d
14/1.75= 8
D = 8
Answer:
A. y = x+10
Step-by-step explanation:
The original test score is x
And in the next assignment it is 10 more means,
x + 10
If the new score is y then it should be equal to the above solution.
Hence, answer is <u>y</u><u> </u><u>=</u><u> </u><u>x</u><u>+</u><u>10</u><u>.</u>
If the length of side of base is 14 inches and height is 6 inches of pyramid a then the volume of pyramid a is 12.5% of pyramid b and volume of pyramid a is 8 times bigger than volume of pyramid b.
Given the length of side of base of pyramid a is 14 inches , height of pyramid a is 6 inches and volume of pyramid b is 3136 cubic inches.
We have to determine the percentage and number of times that volume of b is bigger than volume of pyramid b.
Volume of a square pyramid=base area * height/3
Base area = Side * side
=14*14
=196 inches square.
Volume of pyramid a =196*6/3
=392 cubic inches.
Percentage=Volume of pyramid a / volume of pyramid b*100
=392/3136*100
=12.5%
Let the number of times be x.
So,
392*x=3136
x=3136/392
=8 times.
Hence the volume of pyramid b is 8 times bigger than volume of pyramid a and the percentage is 12.5%.

Answer:
a) 12 inches
b) 144 square inches
Step-by-step explanation:
The complete question has 2 parts to answer:
a. What is the total length of the three fish?
b. How many square inches of water surface do the fish need?
Lets answer:
a)
The total length of three fish are the sum of all the individual fishes' length.
1st is 3.5 in
2nd is 5.5 inches
3rd is 3 inches
Sum is:
3.5 + 5.5 + 3 = <u>12 inches</u>
<u>f is 12</u>
<u></u>
b)
The expression 
gives the total area. We already found f = 12, now the area is:
Area = 12f
Area = 12 * 12
<u>Area = 144 sq. in.</u>
