Answer:
Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.
Step-by-step explanation:
The general equation of a straight line is
y = mx + b
for y = 150x
We have the slope as 150
This is 150 miles/hour
This relates to Jesse’s train speed
for Khalid, we have his own speed obtainable from the graph
The speed is simply the slope of the graph
We proceed to select two points from the graph and find the slope
The points are; ((1,140) and (4,560)
Mathematically, the slope will be;
m = (y2-y1)/(x2-x1)
m = (560-140)/(4-1) = 420/3 = 140 miles per hour
In decimal form: 42.0 ( hope I helped! )
The answer should be around 314.159. The formula is v=pi*r2*h. Plug in the numbers and its v=pi*25*4. That is 25*4 which is 100. Then *pi and it should be it.

Answer:
The measures of the angles are 65° and 80°
Step-by-step explanation:
One of the angles is 35°
We know that the other two angles have a difference of 15°
With this knowledge we can write an equation.
2x symbolizes the two angles
+15 symbolizes the difference between the two angles
145 = 2x + 15
145 - 15 = 130
2x = 130
x = 65
65 is the size of one of the angles.
Next, we add 15 to 65 and we get 80
80 is our second angle
