Answer:
400
Step-by-step explanation:
25% = 1/4
you can ultimately take this fraction and see that if you add two zeroes at the end of '1', you get 100
although, because you added two zeroes at the top, you have to do the same to the bottom.
this shows 400; 25% of 400 is 100.
45machines:20mins
20mins=1/3hour
45machines:1/3hour
times 3
135machins=1hour
135machines per hour
B. 30 in 15
15=1/4 hour
30=1/4hour
times 4
120machines per hour
both produce for 2 hours
A. is 135*number of hours, B is 120 times number of hours
135*2+120*2=
270+240=
510
make 510 machines in 2 hours
Answer:
y = 3x +1
Step-by-step explanation:
The line intersects the y-axis at y=1, so the y-intercept is ...
b = 1
The line rises 3 grid squares for each 1 grid square to the right, so the slope is ...
m = rise/run = 3/1 = 3
Then the slope-intercept equation of the line is ...
y = mx +b
y = 3x +1
26 x 3.14 = 81.64 in. The circumference can by found by multiplying pi by the diameter of the circle.
