Complementary angles add up to 90 degrees
7:8....added = 15

7/15 * 90 = 630/15 = 42 <== one angle is 42 degrees
8/15 * 90 = 720/15 = 48 <== other angle is 48 degrees

Winnie can walk 2 miles in 30 minutes. How many miles can she walk in 2 hours? (Remember 1hr = 60 min) A. 2 B. 4 C. 6 D. 8
Sati [7]
The answer is D-8.

If Winnie walks 2 miles in 30 minutes, 30 minutes is half an hour so for 1 hour which is 60 minutes, she can walk 4 miles, 90 minutes she can walk 6 and for 120 minutes which is 2 hours she can walk 8.

So all I did was multiply 2 by 4 and got 8. The number 4 came from the thought that 2 hours have 4 sets of 30 minutes

What is the slope of the line which passes through (4, 7) and (2, 3)? (5 points)
Basile [38]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = \frac{7-3}{4-2} = \frac{4}{2} = 2

Marquise has 200200200 meters of fencing to build a rectangular garden.
Lera25 [3.4K]

Answer:

2500 Square meters

Step-by-step explanation:

Given the garden area (as a function of its width) as:

A(w)=-w^2+100w

The maximum possible area occurs when we maximize the area. To do this, we take the derivative, set it equal to zero and solve for w.

A'(w)=-2w+100

-2w+100=0

-2w=-100

w=50 meters

Since Marquise has 200 meters of fencing to build a rectangular garden,

Perimeter of the proposed garden=200 meters

Perimeter=2(l+w)

2(l+50)=200

2l+100=200

2l=200-100=100

l=50 meters

The dimensions that will yield the maximum area are therefore:

Length =50 meters

Width=50 meters

Maximum Area Possible =50 X 50 =<u>2500 square meters.</u>
