Answer:
A. 8
Step-by-step explanation:
BE = ½(CD) (midsegment theorem)
BE = 2x - 10
CD = 12
Plug in the values
2x - 10 = ½(12)
2x - 10 = 6
Add 10 to both sides
2x - 10 + 10 = 6 + 10 (addition property of equality)
2x = 16 (addition property of equality)
Divide both sides by 2
2x/2 = 16/2
x = 8 (division property of equality)

Michael can mow 5 lawns in 36 minutes. At this rate, how long will it take him to mow 15 lawns?
Answers
Answer:
It would take him 108 minutes to mow the lawn.
Step-by-step explanation:
We can do proportion.
[tex] \frac{5 \: lawns}{36 \: minutes} = \: \frac{15 \: lawns}{x} [/tex]
[tex]36 \times 15 = 540 \\ 5 \times x = 5x[/tex]
[tex] \frac{540}{5} = \frac{5x}{5} [/tex]
[tex]108 = x[/tex]

Fint the are and perimeter of the shape at the bottom
Answers
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet
Step-by-step explanation:
Area:
For the area of the square, you're going to use the formula length times width. The length and width are both 7, so you'll do 7 times 7, which is 49. Next, you need to find the area of the triangle. It's a bit more confusing since they give you the hypotenuse (7.6 ft), but they did that to try and trick you. The area of a triangle is length times width divided by two. So, you're going to take the width (3) and multiply it by the length (7). The length is 7 because the length of the square and the triangle are the same since the bottom of the triangle is the same length as the top of the square. Anyway, using the formula, you will do 7 times 3 divided by 2, which is 21 divided by 2, which is 10.5. Add the 10.5 to the 49 we got from the square, and you'll get 59.5 feet squared.
Perimeter:
For the perimeter, you just need to add the side lengths. Starting at the top and going to the right, we can add 7.6+7+7. We don't get the left length, but it's the same as the rest of the square (7) because all sides of a square are equal. So, now we have 7.6+7+7+7, which is 28.6, and we just need the last one which is 3, so the final answer is 31.6 feet.
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet
