Answer:
2800 in^3
Step-by-step explanation:
Calculate the volume as normal, but take 1/10 of the result. Since volume is length*width*height, we have 50*28*20 which is 28000. 1/10 of that is 2800. So the volume when scaled down by a factor of 1/10 is 2800 in^3
I got 7.1 x 10^(-11) but it's been a few years so I could've done it wrong
5x - 2y = 10
Isolating y:
-2y = 10 - 5x
y = (10 - 5x)/(-2)
y = 10/(-2) + (-5x)/(-2)
y = -5 + 5/2x
This equation has the slope-intercept form with a slope of 5/2 and a y-intercept of -5
The answer is true because 8 times 125 (8x125) is equal to 1000 therefore Tiara is correct
Answer:
n = d+30 since he has 30 more nickels than dimes, to make them equal you have to add 30 to the dimes.
:
n+d = 150 substitute for n:
d+30+d = 150
2d = 120
d = 60 he has 60 dimes and 150-60 = 90 nickels
