Answer:
B. 152 square inches
Step-by-step explanation:
The surface area equation is:
SA=2LH+2LW+2WH
In this problem, length is 6, width is 1 and height is 10. If we plug those numbers into the equation we have:
SA=2(6)(10)+2(6)(1)+ 2(1)(10)
(simplify)
SA=120+12+20
(simplify)
SA=152
Answer:
y=-3x+20
Step-by-step explanation:
3/4x+1/4y=5
-3/4x -3/4x
1/4y=5-3/4x
divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)
Your answer is y=-3x+20
Answer:
y=(3/2)x + 1
Step-by-step explanation:
use formula y=mx+b
M is slope
B is y intercept
use point (2,4) for Y2 and X2, and point (0,1) for Y1 and X2 to find the slope.
(Y2(4) - Y1(1))/ (X2(2) - X1(0)) =
(4-1)/(2-0)= 3/2 for slope=M
y intercept is just the point found on the y axis (0,1) so it's just 1. B=1
so then plug in the numbers for the variables.
y=(3/2)x + 1
.4 and .40 are indeed the same amount.
We usually drop the 0 in the 100'ths place when it is not necessary for indicating money or solving a problem with 2 decimals.
Also realize that .400 .4000 etc are all the same as well.
