Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
Answer:
y=-3x+7
Step-by-step explanation:
slope intercept from is y=mx+b where m is slope and b is the intercept. so far we can plug in what we know. -8=y; 5=x; and -3=m.
(-8)=(-3)(5)+b. now solve for b which would give us b=7. now we plug in m and b int y=mx+b which gives us
y=-3x+7
First we distribute 3 into 2x and -4.
3 x 2x = 6x
3 x -4 = -12
That will make the left side of the equation:
6x - 12 = 5x + 2
Now we subtract 5x on both sides of the equation.
x - 12 = 2
Finally we add 12 on both sides of the equation.
x = 14 is the answer
The cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.
A car averages 32 mpg and gas costs $1.97 per gallon.
By unitary method for 866 miles, average would be,
= 866/32
= 27.0625 miles per gallon
and the cost to pay for the gas if this car made a trip of 866 miles would be,
= 27.0625 × $1.97
= $53.31
Therefore, the cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.
