Whats the surface area?

Answer:

Total Area = 1070 m^2

Step-by-step explanation:

we have 4 different surfaces

  1. the "ramp"
  2. the triangles (2) one for each side
  3. the bottom rectangle
  4. the back rectangle

1. the ramp

A_r = 15\times 30\\\\A_r = 450

2. the triangles

since they are the same we just multiply by two

A_t = \frac{8\times 10}{2}\\\\A_t = \frac{80}{2}\\\\A_t = 40

so the areas of the two triangles is

2A_t = 2(40)\\\\2A_t = 80

3. the bottom rectangle

A_{bot} = 10\times 30\\\\A_{bot} = 300

4. the back rectangle

A_{back}  = 8\times 30\\\\A_{back} = 240

now add them together

A_T=A_r+2A_t+A_{bot}+A_{back}\\\\A_T = 450+80+300+240\\\\A_T = 1070\: m^2

ozzi

Answer:

I think the answer is 21

Step-by-step explanation:

The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.

4x + 2y = 10 identify the slope and the y intercept ​
Alecsey [184]

Answer:

Slope in this case is -2

Y-Intercept in this case is 5, or (0, 5)

Step-by-step explanation:

In order to identify the slope and y-intercept, you must put the equation is y = mx + b form. This is quite simple! Don't panic! You got this :)

4x + 2y = 10

Move x to the right

2y = -4x + 10

Divide by y's coefficient

y = -2x + 5

Slope in this case is -2

Y-Intercept in this case is 5
