the length of a rectangle is 4 feet longer than its width.its area is 32 square feet.what are its dimensions?
Answers
Answer: Length=8, Width=4
Step-by-step explanation: I did this by trial and error, but you can also use an equation. The length is x+4, the width is x. Your equation would be x(x+4)=32. That is equal to x^2+4x=32. Solve this by completing the square. X^2+4x+ (4/2)^2=32+ (4/2)^2
X^2+4x+4=36. (X+2)(x+2)=36. X+2=6, x=4.

An employee's time at work increased from 32 hours per week to 40 hours per week. By what percentage did the
time at work per week increase?
Answers
If you add 25% to 32 your answer will be 40
Answer:
You have to take the ratio so you divide the new value on the old value and compare It with 100 so you write
(40)/(32)=(x)/(100)
And this means that x = 125
So the ratio of the increase of the new time is 125%
But the real increase is 125 - 100 = 25%
Gaurav takes 15 rounds of a rectangular park whose length is twice its breadth. If the total distance covered by Gaurav is 900m find the length and breadth of the park
Answers
Answer:
length = 20 breadth = 10
Step-by-step explanation:
divide 900 by 15
= 60
60 divided by 6 because the length is twice the breath
60 / 6 is 10
so ten is the breadth of one side and double that is 20 so the length is 20

7) Which variable equals 101?
Answers
Answer:
5) ?
6) y = 55
7) no variable equals 101 in this triangle
Step-by-step explanation:
5) There was no question for 5
6) This is the answer because:
x = 79: 65+36+x = 180, 101+x = 180, x = 79
z = 144: 180 - 36 = 44
y = 55: 36+79+(y+10) = 180, 115+(y+10) = 180, y+10 = 65, y = 55
Hope this helps!

Find the length of side x in simplest radical form with a rational denominator
Answers
Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so
sin 30 = opposite/hypotenuse
1/2 = x/6 ∵ sin 30 = 1/2
1/2 × 6 = x
6/2 = x
3/1 = x
Therefore, the length of x=3/1
Eight toy camels and three toy pigs cost Gary $85. Twelve toy camels cost Sherry $96. Assuming everyone bought their toys at the same store and there were no discounts, what is the cost of two toy pigs?
Answers
Answer:
2 toy pigs cost $14
Step-by-step explanation:
If 12 toy camels cost $96, I can solve ($96 / 12 = $8) to find the price of 1 toy camel. Now, I know that 1 toy camel costs $8.
If 8 toy camels and 3 toy pigs cost $85, I can multiply the price of 1 toy camel by 8 and solve ($8 x 8 = $64).
Next, I can subtract Gary's total cost by the toy camels to find how much was spent on 3 toy pigs. ($85 - $64 = $21) Therefore, 3 toy pigs cost $21.
Then, I can solve ($21 / 3 = $7) to find the price of 1 toy pig. Finally, I can multiply ($7 x 2 = $14) to find that 2 toy pigs cost $14.
Answer:
Two toy pigs cost $14.
Step-by-step explanation:
Gary bought 8 toy camels and 3 toy pigs for $85.
Sherry bought 12 toy camels for $96.
Thus, each toy camel cost $96/12=$8
Now we know Gary spent 8*$8= $64 in toy camels.
The rest of the $85, $85 - $64 = $21 was spent on the 3 toy pigs, thus each toy pig cost $21/3=$7
If one toy pig costs $7, two toy pigs cost $14.

Vincent purchased a scooter for $124 before tax. The store adds a 7.8% sales tax to every purchase. How much did Vincent pay for the scooter, to the nearest penny?
Answers
Step-by-step explanation:
Original price of the scooter = $124
Sales Tax = 7.8%
Price of the scooter after tax = 124 + 7.8%(124)
= 124 + 7.8/100 x 124
= 124 + 3.9/50 x 124
= 124 + 1.95/25 x 124
= 124 + 0.39/5 x 124
= 124 + 0.39 x 24.8
= 124 + 9.672
= 133.672
Therefore, after tax the scooter will cost $133.672.
