A number that is 4 less than 2 is -2
Answer:
234ft²
Step-by-step explanation:
Surface of the triangular prism
= ab+3bh
= (6ft×13ft)+(3×13ft×4ft)
= 78ft²+156ft²
= 234ft²
Hence, the surface area of the given triangular prism is 234ft².
Answer:
(2, 4)
Step-by-step explanation:
To solve this system, the easiest way would be to use the substitution method. You can simply plug in, or substitute the value of y from the second equation, which is -x + 6, into the first equation. So you would get:
-x + 6 = 3x - 2
6 = 4x - 2
8 = 4x
2 = x.
To find y, just substitute the value of x, which is 2, into either equation:
y = 3(2) - 2
y = 6 -2
y = 4.
Make sure you write your answer as an ordered pair! So, the final answer is (2, 4). Hope that helped! :)
we conclude that the dimensions and area of the scaled figure are:
- l₂ = 48 in
- w₂= 32in
- A₂ = 1,536 in^2
How to find the dimensions of the large rectangle?
First, we know that the large rectangle is the smaller rectangle rescaled, with a scale factor k = 4.
This means that each dimension of the smaller rectangle must be multiplied by 4 to get the correspondent dimension on the larger rectangle.
The dimensions of the smaller rectangle are:
l₁ = 12in
w₁ = 8in
Then the correspondent dimensions of the large rectangle are:
l₂ = 4*12in = 48 in
w₂= 4*8in = 32in
Now, the area of the large rectangle is given by the product between the two dimensions, we will get:
A₂ = 48in*32in = 1,536 in^2
Then, we conclude that the dimensions and area of the scaled figure are:
- l₂ = 48 in
- w₂= 32in
- A₂ = 1,536 in^2

Answer:
12 hr. mowing lawns
28 hr. working at Mc Donalds
Step-by-step explanation:
Let t = time mowing lawns
then 40 - t = time working at McDonalds
7,5(40 - t) + 6t = 282
300 - 7.5t + 6t = 282
-1.5t = -18
t = 12 hr. mowing lawns
40 - t = 40 - 12 = 28 hr. working at Mc Donalds
