1. Divide the new dimension by the original dimension:
2/8 = 1/4
3/12 = 1/4
6/24 = 1/4
The scale factor was 1/4 scale
2. Same steps as number 1.
12/3 = 4
16/4 = 4
20/5= 4
The scale factor was 4
Answer:
2.5
Step-by-step explanation:
because 5÷2=2.5 there you go
The answer is
140/16 =
8.75
Answer:
22
Step-by-step explanation:
convert into mixed fraction
11/2 divided by 1/4
then keep change flip
11/2 *4/1
then cancel common factor and cross multiply
11*2/1*1=22
With that information we can create the equation
10x + 5000 = 20x
where x is the number of earphones produced
10x is the cost to make each earphone, 5000 being the fixed costs of manufacturing, and 20x being the total revenue of selling each earphone for $20
Now to solve the equation:
subtract both sides by 10x
10x - 10x + 5000 = 20x - 10x
5000 = 10x
Now divide both sides by 10
5000/10 = 10/10 x
500 = x
Answer: D
