Answer:
50 minutes = B
Step-by-step explanation:
Andre can run 5 miles in 40 minutes
for 1 miles = 40/5 = 8 minutes
1 mile = 1.61 kilometres
x = 10 kilometres
x= (10x1)/1.61= 10/1.61 = 6.21miles
- for 1 miles = 40/5 = 8 minutes
- 6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B

"At least" counts up.
p=32\%=0.32
p=32%=0.32
q=1-0.32=0.68
q=1−0.32=0.68

Answer:
y = -1/2x - 4
Step-by-step explanation:
The slope intercept form of a line is y = mx + b. The slope is -1/2 so substitute m = -1/2. The y-intercept is b so substitute b = -4.
y = -1/2x - 4
Answer:
2255.31 cu.m
Step-by-step explanation:
Volume of a cylinder = πr²h
Given radius r = 6.5m
Height h = 17m
Volume = π × 6.5²×17
Volume = 3.14×6.5²×17
Volume of the cylinder = 2255.31cu.m
