Answer:
Length of the mural should be 20.78 m
Step-by-step explanation:
Let the length of the mural be L and the width W
Area = L × W = 60 m²
Ticket wants the L = 15 + 2W
Substitute for L in the Area eqn
(15 + 2W) × W = 60
15W + 2W² = 60
2W² + 15W - 60 = 0
Solving the quadratic equation
W = 2.89 m or - 10.39 m
Obviously, the width cannot be negative,
So, W = 2.89 m
L = 15 + 2W = 15 + 2(2.89) = 20.78 m
Check - L × W = 20.78 × 2.89 = 60 m²
Hope this Helps!!!
Answer:
5/42
Step-by-step explanation:
To solve this problem, you have to divide 7 and 5/6 to find the unit rate (how much hours it takes to do one task).
- Write what you know into a ratio
<u>7 tasks</u>
5/6 hour
2. You want to know how many hours one task takes, so make that a ratio as well.
<u>7 tasks </u> <u> 1 task</u>
5/6 hour ? hour
Ask yourself what do you do to the 7 in the numerator to get to one.
That's right! you divide by 7! And whatever you do to the numerator you do to the denominator (and vise-versa). Therefore if you divide the numerator(7) by 7 to get 1, you divide the denominator (5/6) by 7 as well.
5/6 divided by 7 is 5/42 meaning it takes the robot 5/42 hour to complete one task.
<u>1 task</u>
5/42 hour
