uysha [10]3 years ago

Answer:

y = 60x + 50

Step-by-step explanation:

Let y be the total price and x be the months passed,

Since the enrollment fee is $50, the y-intercept would be 50 regardless of the months passed. Also, since the price increases by $60 every month, we know the gradient is 60.

Therefore, the equation is y = 60x + 50

Maddie is participating in the first round a math competition. She writes one contest a month in each of the first ten months of
ad-work [718]

The correct answer is 85 points in each contest

Explanation:

To solve this problem, the first step is to find out how many points Maddie has and then how many points she still needs to get a total of 750 points. Additionally, to do this, the correct process is to multiply the average points by the number of contexts.

In the first five contests, she obtained 68 points average

5 x 68 = 340 points in the first five contests

In the three following contests, she obtained 80 points on average

3 x 80 = 240 points

Now, let's add the points and find how many points she is missing to reach 750 points

340 + 240 = 580

750 - 580 = 170

Finally, let's divide the points missing by 2 because there are still two contests and Madie needs to get the 170 points in these two.

170 ÷ 2 = 85 points

Maddie needs to get 85 points on average to complete her goal of 750 points

The distance a spring will stretch varies directly with how much weight is attached to the spring. If a spring stretches 9 inche
masha68 [24]
<span>Let the distance a string will stretch be l, and the weight attached to the string be w, then l = kw. 9 = 100k => k = 9/100. l = 9/100 w. Therefore, when a weight of 90 pounds is attached, l = 9 / 100 x 90 = 810 / 100 = 8.1 inches.Hope I helped! :) Cheers!I hope that I could help :) sometines those questions are tricky.

Miguel buys 100 feet of fence to enclose a rectangular area of his backyard so his dog can run freely. What is the maximum area,
sdas [7]
Suppose the length of the triangle is x, if the perimeter of the rectangle is 100 ft, the width of the rectangle will be (50-x) ft.
Area of rectangle will be:
A=length*width
A=x(50-x)
A=50x-x^2
at maximum area, dA/dx=0
thus
dA/dx=50-2x=0
solving for x we get
2x=50
x=25
thus for maximum area length=25 ft
the size of the width will be
50-x=50-25=25 ft
thus the maximum area will be:
25*25=625 sq. feet
