I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>
If you would like to know what is the area of the wall, you can calculate this using the following steps:
area = length * width
area = 9 1/3 feet * 8 1/8 feet = 28/3 feet * 65/8 feet = 455/6 = 75 5/6 square feet
The area of the wall is 75 5/6 square feet.
If the mural is 100 square feet, it won't fit on the wall, because 100 > 75 5/6.
Shiela is 0.61 meters taller than her son.
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
