Answer:
The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Step-by-step explanation:
The first step will be to find the diagonal of the rea life mural.
We can use Pythagoras' Theorem to do this.
Diagonal =
=47.43 feet.
Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.
This will be 47.43 / 6.3 units = 7.53.
The scale factor is 7.53
To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.
This will be
Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976
Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Answer:
Large boxes = 40 lbs.
Small boxes = 15 lbs.
Step-by-step explanation:
L = Large Box
S = Small Box
I started by making the equations, L + S = 55 and 60L + 50S = 3150. I made the first equation L = 55 - S and substituted that in for L in 60L + 50S =3150. After finding S, I plugged that back into L + S = 55 and got the answers.
Start by subtracting 2. You end up with -5x=20. Because the five is negative, the second number must be negative, because two negatives always make a positive in multiplication. Pick the only negative answer, which is D, -4
Answer:
8/3 = 1/x or x = 3/8
Step-by-step explanation:
Set up the ratio
(2/3)/(1/4) = 1/x
solve for x
8/3 = 1/x or x = 3/8
