Answer:
Total distance covered = 436 yards
Step-by-step explanation:
Walking path BE joins the midpoints B and E of the sides AC and AD.
By midsegment theorem,
"Line joining midpoints of two sides of a triangle is parallel and measure half of the third side"
m(BE) =
CD = 2(BE)
CD = 2(74) = 128 yd
From starting point D,
DE = 107 yd
EB = 74 yd
BC =
= 127 yd
CD = 128 yd
Total walking distance = DE + EB + BC + CD
= 107 + 74 + 127 + 128
= 436 yd
Total distance covered = 436 yards
Answer: x + 6
Step-by-step explanation:
We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.
Given:
2(3/5x+3)
Distribute:
2 * (3/5x) + (2 * 3)
6/5x + 6
Answer:
x + 6
Answer: If you take 4 times 6 you get 24, so take 3*6 to get an 18-foot shadow. 4:3=24:18. I hope this helps. I'm not sure what your choices are, though.
Answer is c. Because it cuts off
Numerator:
315= 3^2* 5* 7
Denominator:
1575= 3^2* 5^2* 7
Therefore,
315/1575
= (3^2* 5* 7)/ (<span>3^2* 5^2* 7)
= 1/5
Hope it helps.</span>
