First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.
3=4=7
Next, you divide this amount into your total amount of cans of soda.
28/7=4.
This means that for each one in the ratio, there is 4 cans. So you multiply both numbers in the ratio by 4.
3*4 = 12
4*4=16
So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.
Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
Answer:
The correct option is B.
Step-by-step explanation:
It is given that Joe paid 14.00 for a board game this is 70% of the original price what is the original price.
Let the original price of board game be x.
Multiply both sides by 10.
Divide both sides by 7.
The original price is 20. Therefore the correct option is B.
You can use the trig ratios. Draw a diagram to see which one is appropriate.
Tan would be used.
Tan29=x/20
20Tan29=x
