Answer:
4.5 miles per hour
Step-by-step explanation:
Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Distance = 3/4 of a mile
Time taken on Monday = 1/6 of an hour.
What is Selma's unit rate in miles per hour for Monday's run?
Unit rate in miles per hour for Monday's run = distance ÷ time taken
= 3/4 ÷ 1/6
= 3/4 × 6/1
= (3 * 6) / (4 * 1)
= 18/4
= 4.5 miles per hour
Unit rate in miles per hour for Monday's run = 4.5 miles per hour
Answer:
y = 0 and x = 6
y = 2 and x = 3
y = 4 and x = 0
y = 6 and x = -3
Step-by-step explanation:
2x+3y=12 is the equation of a straight line.
There are infinite number of solutions, but here you're probably looking for solutions where x and y are whole numbers. Trial and error will find you some, although if you examine the equation closely you see that if x is a multiple of 3 and y is a multiple of 2, then they produce terms that are the LCM (least common multiple) of 2 and 3, namely 6. That's the logic in the whole number solutions.
The sales tax is the additional cost with a value of a fraction of the gross cost. Let's compute first the gross cost:
Gross cost = 3($1.59) + 2($3.25) = $11.27
The sales tax is, therefore, 7.25% of $11.27.
Sales Tax cost = $11.27(0.0725) = $0.817
The total purchase is equal to the gross cost and the sales tax cost.
Total Purchase Cost = $11.27 + $0.817 = $12.09
Answer:
mean- 2
Step-by-step explanation:
To find the mean, add ALL the values, and divide by # of values
2+4+3+1+2+1+3+2+4= 22
Divide 22 by # of students surveyes, 11
22/11= 2
Mean= 2
Yes they are equal because lets say the rectangle's area is 14 and if you divide 14 into 2 it will be 7 and 7+7=14
