Answer:

x = tex]5\frac{\textup{7}}{\textup{8}}\ in[/tex]

Step-by-step explanation:

Given:

Total height of the bench = 18 in

Depth of the stone bench = 3\frac{\textup{3}}{\textup{8}}\ in = \frac{\textup{27}}{\textup{8}}\ in  = 3.375 in

Measure of stones = 3\frac{\textup{1}}{\textup{2}}\ in = \frac{\textup{7}}{\textup{2}}\ in  = 3.5 in

measure of another stone =  5\frac{\textup{1}}{\textup{4}}\ in = \frac{\textup{21}}{\textup{4}}\ in  = 5.25 in

let the height of the third stone be 'x'

Now,

The total height of the bench = depth of bench + Measure of two stones + x

18 = 3.375 + 3.5 + 5.25 + x

or

x = 18 - 12.125

or

x = 5.875 in

or

x = tex]5\frac{\textup{7}}{\textup{8}}\ in[/tex]

Help me find the surface area of the candle
ExtremeBDS [4]

Answer:

Easy!

Step-by-step explanation:

1) To find the surface area of a regular triangular pyramid, we use the formula SA = A + (3/2)bh, where A = the area of the pyramid's base, b = the base of one of the faces, and h = height of one of the faces.

or

2)Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral surface area of the pyramid. Add the base surface area and the lateral surface area.

What is the solution to 4x-3y=10
Ainat [17]
Solving for y:
4x-3y=10. (subtract 4x on both sides)
-3y=-4x+10. (divide by -3 on both sides)

y=4/3 x+10/3
