Answer:
41 minutes
Step-by-step explanation:
We are given;
Time spent on homework = 90 minutes
Time spent reading = 2/3 hours = 2/3 × 60 minutes = 40 minutes
Time spent making lunch = 540 seconds = 540/60 minutes = 9 minutes
We want to find how many more minutes Roberto spent doing homework than he did reading and making his lunch.
Thus;
Time spent on reading and making lunch = 40 + 9 = 49 minutes
Hence, the word "how many more" means we will subtract 49 from 90.
So, "how many more minutes" = 90 - 49 = 41 minutes
Step-by-step explanation:
Multiply the length by the width and your answer will be there.
Answer:
Step-by-step explanation:
Here the given equations are,
------- (1)
---------(2)
Since we know that the solution of the above equation will find in the intersection point of these equations.
For this we have to solve these equations.
Subtracting equation (1) by equation (2)
We get,
⇒ x = -0.75488 ≈ - 0.80
Which is the x-coordinate of the solution of equations f(x) and g(x).
In Options,
Since, Only - 0.8125 is nearby to -0.80.
Thus, the approximate solution of f(x) and g(x) is
The answer is 0.7/1 of a wall per person
To find the answer, we can first find the distance each of them have, then divide it by their speed to find the time needed.
Distance Steve need to travel: 300 feet
Distance Paula need to travel:
300+175(behind steve) = 475 feet
Time needed respectively:
Steve: 300 ÷ 9 = 33.33.. seconds
Paula: 475 ÷ 15 = 31.66... seconds
As we can see from the result, Paula would take less time to reach the goal (31.66<33.33),
therefore, Paula win the bike race by:
33.33-31.67
=1.66...
≈1.67 feet
Thus Paula won by 1.67 feet.
Hope it helps!
