Answer:
12 sandwiches
Step-by-step explanation:
If 3 sandwiches cost $20
Then x sandwiches cost $80
3----20
x----80
20x=3 x 80
20x=240
x=240/20
x=12 sandwiches
Answer:
A. -1/5
B. 8 gallons
C. 75 miles driven
Step-by-step explanation:
Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.
Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.
Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.
Answer: it would take them 40/13 hours
Step-by-step explanation:
If Naomi were to paint her living room alone, it would take 5 hours. it means that the rate at which she paint her living room alone is 1/5
Her sister Jackie could do the job in 8 hours. it means that the rate at which Jackie paint the living room is 1/8
If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be
1/5 + 1/8 = (8 + 5)/40 = 13/40
Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,
13/40 = 1/t
t = 40/13 hours
ANSWER:
0.1347 ROUNDED to the nearest tenth is 0.1
Step-By-Step Explanation:
0.1347 rounded to the nearest thousandth is 0.135 and 0.135 rounded to the nearest hundredth is 0.14 so because the value of the digit in the hundredths place is 4, you round your answer to the nearest tenth of 0.1
