Surface area is the sum of the areas of each side of a three dimensional object.

There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.

So the surface area is:

2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2

Alenkinab [10]

Answer:

7. y-1=4(x-2)

y-1=4x-8

y=4x-7

8. y-2=6(x--7)

y-2=6x+42

y=6x+44

11. y-3=2(x-1)

y-3=2x-2

y=2x+1

12. y-4=-1(x-1)

y-4=-x+1

y=-x+5

Solve for y, z, x or t:
Rus_ich [418]

Answer:

Step-by-step explanation:

if~it ~is ~y+\frac{y}{a} =b\\then~\frac{ay+y}{a} =b\\ay+y=ab\\ y(a+1)=ab\\ y=\frac{ab}{a+1} \\

z-a=\frac{z}{b} \\z-\frac{z}{b} =a\\ \frac{bz-z}{b} =a\\bz-z=ab\\z(b-1)=ab\\z=\frac{ab}{b-1}

The answer ASAP I don’t understand this at all
RSB [31]

Answer:

T = 530N + 250

Step-by-step explanation:

For the first plan, Heather will deposit $250 and then save $135 per month.

So, that is 250 + (135 x N) where N is the number of months she saves the $135.

So if it is for 3months,

We will have:

t¹ = 135N + 250

= 250 + (135 x 3)

= 250 + 405

= $655

For the second plan, there is no initial deposit, but she will save $395 per month.

That is 395 x N

t² = 395N

For 3months, we have 395 x 3 = $1185

Therefore the total for both plans in 3months = 655 + 1185 = $1840

Equation relating T to N

T = t¹ + t²

T = (135N + 250) + 395N

T = 135N + 250 + 395N

T = 530N + 250
