Answer:
45 or least
Step-by-step explanation:
I'm guessing that the angel is acute
3 is B
4 is D
I can figure out 5, Im kinda bad at plotting.
Since the temperature keeps increasing by 2°F each hour for the next 7 hours, the graph will be a straight line graph.
Let T be temperature
t be the time at temperature T
At t₁ = 0, T₁ = 43°F
At t₂ = 1, T₂ = 45°F (temperature increase by 2°F)
Using the straight-line formula to get the equation of the graph. The equation is expressed as T = mt + b
- m is the slope
- b is the intercept
Get the slope
Get the intercept
Substitute m = 2 and the coordinate (0, 43) into the expression
43 = 2(0) + b
43 = b
b = 43
Get the equation of the line
T = 2t + 43
Graph the equation of temperature over time

Answer:
16
Step-by-step explanation:
Lets first start off with what we know. We know that if we have 26 trucks with a 4-ton payload each, we will be able to unload a freight train. In total, unloading a freight train will require a 104-ton payload because...
(26 trucks) x (4-ton payloads) = 104 tons
Since we know that a freight train can carry 104 tons, we can just do some simple math to figure out the rest of the problem.
(? trucks) x (6.5-ton payloads) = 104 tons
All we do now is divide 104 by 6.5 to get our answer.
104 / 6.5 = 16
Volume=height times area of base
area of base=pi times r^2
volume=(h)(pi)(r^2)
diameter=2r
diameger=8
8=2r
divide 2
4=r
h=3 times r
h=3r
r=4
h=3(4)
h=12
r=4
h=12
pi=3.14
subsitute
volume=(12)(3.14)(4^2)
volume=(12)(3.14)(16)
volume=602.88 in^3
