Think of investments. If you were to invest $100 into a company and receive $200 dollars, then you would have made $100 in profit, which is 100% of your initial amount. So, if you were to invest $100 and receive $250 dollars in profit, then you would have made an extra $150, which is even more than your initial amount of $100. In this case, you would have made a 150% increase on your money.
Perimeter:
p = 2b + 2h = 68
b = 4h - 6 (per problem statement)
substituting for b in the perimeter equation:
p = 2(4h - 6) + 2h = 68
(2)(4h) - (2)(6) + 2h = 68
8h - 12 + 2h = 68
10h - 12 = 68
10h = 68 + 12
10h = 80
h = 80/10
h = 8
b = 4(8) - 6 = 32 - 6 = 26
p = 2(26) + 2(8)
p = 52 + 16 = 68 . . . [OK]
b = 26 cm
h = 8 cm
Answer:
D) 24,32,40
Step-by-step explanation:
Sense this is a right triangle, I will use the Pythagorean theorem to solve this problem. Use the following formula: a^2 + b^2 = c^2. 40 would be c. 40 x 40 = 1600. 32 x 32 = 1024. 24 x 24 = 576. Since 576 + 1,024 equals 1600, this means the answer would be D. Remember, that you can only use the Pythagorean Theorem method on right triangles.
1,600 = 576 + 1024.

Given width is 24 less than length.
W=L-24
Perimeter = 2(W+L)=2(L-24+L)=4L-48
But we're also given perimeter = 172'
Therefore 4L-48=172
solve for L
4L=172+48=220
L=55'
W=55-24 = 31'
Check: Perimeter = 2(W+L)=2(31+55)=2*86=172' good!
Answer: The dimensions of the garden are 31' * 55'
Answer: 75.36mm
i don’t know how to explain it i’m sorry
