Answer:
88 cm²
Step-by-step explanation:
Top small rectangular prism: (1 x 2 x 2) + (3 x 2 x 2) + (1 x 3) = 19
Bottom: (6 x 2 x 2) + (2 x 3 x 2) + (5 x 3) + (6 x 3) = 69
SA = 19 + 69 = 88
2000 for RF and IT and EF per month...
30% goes to retirement.....0.30(2000) = 600
IT is 80% of RF.....0.80(600) = 480
remainder goes to EF.......2000 - (600 + 480) = 920
which represents 20% of his salary...
920 = 20% of salary (s)
920 = 0.20s
920/0.20 = s
4600 = s.........he earns 4600 per month <==
Answer:
Area of the wall without the doorway = 67.5 - 21 = 46.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Step-by-step explanation:
i) let length of smaller side of trapezoidal wall, a = 22 feet
ii) let length of longer side of trapezoidal wall, b = 23 feet
iii) height of trapezoidal wall, h = 3 feet
iv) area of trapezoidal wall =
=
= 22.5
3 = 67.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
v) area of door = 7
3 = 21 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
vi) Area of the wall without the doorway = 67.5 - 21 = 46.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Answer:
![6x -7y = 21](https://tex.z-dn.net/?f=6x%20-7y%20%3D%2021)
Step-by-step explanation:
The
-intercept of a line is the
value when
. In the equation
, we can solve for its equation when we plug in
.
Solving for
when
:
.
So the
-intercept of the equation
is
.
To find what equation has the same
-intercept, we can do the same process for each equations given by the choices. However, I can see that the equation,
, has the
-intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for
when
:
![6x -7y = 21 \\ 6(0) -7y = 21 \\ 0 -7y = 21 \\ -7y = 21 \\ \frac{-7y}{-7} = \frac{21}{-7} \\ y = -3](https://tex.z-dn.net/?f=6x%20-7y%20%3D%2021%20%5C%5C%206%280%29%20-7y%20%3D%2021%20%5C%5C%200%20-7y%20%3D%2021%20%5C%5C%20-7y%20%3D%2021%20%5C%5C%20%5Cfrac%7B-7y%7D%7B-7%7D%20%3D%20%5Cfrac%7B21%7D%7B-7%7D%20%5C%5C%20y%20%3D%20-3)
