A yard has a perimeter of 168 feet. If times the length of the yard equals seventeen times the width, what are its dimensions?
Answers
Answer: See Explanation
Step-by-step explanation:
Your question isn't complete but let's reframe it as:
A yard has a perimeter of 168 feet. If four times the length of the yard equals seventeen times the width, what are its dimensions?
Therefore, 2L + 2W = 168 ....... i
4L = 17W ........ ii.
From equation ii,
L = 17W/4 ........ iii
We would then slot the value of L into equation i
2L + 2W = 168
2(17W/4) + 2W = 168
17W/2 + 2W = 168
17W + 4W = 336
21W = 336
W = 336/21
W = 16
Since L = 17W/4
L = (17 × 16)/4
L = 68
The dimensions are 16 feet and 68 feet

Answers
Answer:
y = -1/2x + 5/2
Step-by-step explanation:
Mid-point = ((-1 + 3) / 2 , (-5 + -1 )/ 2)
= (1 , -3)
Gradient = (-1 - -5 )/(-3 - -5)
= 2
m1_ = -1/2
y = mx + b ( we have to find b)
y = -1/2 x + b (we will use mid point x = x and y = y)
-3 = -1/2 (1) + b
-3 = -0.5 + b
b = -3 + 0.5
b = -5/2
so,
y = -1/2x + 5/2

0.151
Step-by-step explanation:
Given :
21.1 + 45.99 + 26.0 = 93.09
15.55 + 21.61 - 12.333 = 24.827
14 + 0.8 + 9.33 = 24.13
14.5 * 190 = 2755
5.1 * 2.5 = 12.75
0.15 ÷ 0.991 = 0.151
Jessica is shopping for a new car. She found a blue car that has a 12-gallon gas tank and can go 384 miles on one tank. She found a silver car that has a 14-gallon gas tank and can go 504 miles on one tank. Which car gets better gas mileage?
Answers
Answer:
Silver car
Step-by-step explanation:
It seems pretty hard but it's actually REALLY easy. gas mileage means the number of miles you can go on a particular amount of gallons. But the gallons have to be the same for both cars so that it's fair.
so let's go with 10 gallons. pretty broad number right?
so to get 12 gallons(the gallons for the blue car) to 10, We divide it by 12 then multiply it by 10. Try it yourself, (12/12)*10=???
then we do that to 384 (the miles for the blue car)
(384/12)*10=320
so 320 is the mileage for the first car. Repeat the steps for the silver car!
(14/14)*10=10
so then: (504/14)*10= 360.
So which is bigger, 320 or 360?
360 is bigger, meaning it has better gas mileage.

which equation represents the area,y, of the trapezoid
Answers
Answer:
C. y = x^2 + 4x.
Step-by-step explanation:
Area of a trapezoid = (h/2)(a + b) where h is the altitude and a and b are the lengths of the parallel sides.
So here
Area y = (x/2)(8 + 2x)
= 8x/2 + 2x^2/2
= 4x + x^2.

If a plant is planted and starts its height at 3 in and grows 2 in every week. when will the plant be 60 in tall?
Answers
Answer:
28.5 weeks
Step-by-step explanation:
First, subtract 3 from 60:
60 - 3
= 57
Then, divide this by 2:
57/2
= 28.5
So, the plant will be 60 in tall after 28.5 weeks
Which equals 57
Then divide 57 by 2 which equals
28.5 weeks

Determine this one algebraically
Answers
Answer:
x = 5
y = 5
Step-by-step explanation:
In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...
2x - x = 5
1x = 5
x = 5
Now we plug that value of x into the second equation
4x - 2y = 10
4(5) - 2y = 10
20 - 2y = 10
-2y = -10
y = 5
Finally, we can see that both x and y have a value of 5.
