You read 50 pages in an hour your sister reads 40 pages in an hour how many more pages did you read than your sister reads in 1/

Elena-2011 [213]

To start to figure this problem out, we can first figure out how many more pages you read in an hour compared to your sister.

50 - 40 = 10, so you read 10 more pages in 1 hour.

Now we have to figure out how much more you would read in 1/2 an hour. Since 1/2 an hour is 1/2 of an hour, we can divide 10 by 2 to figure out how many more pages you read in an hour compared to your sister. 10 divided by 2 is 5, so you read 5 more pages every half hour.

Which is greater, less than, or equal to. 6 pints is _______ 60 fluid ounces

Liono4ka [1.6K]

The answer is 6 pints equal to more than 60 fluid ounces

1 pint = 16 ounces.
6 pints = x

Use the proportion:
1 pint : 16 ounces = 6 pints : x
x = 16 ounces * 6 pints : 1 pint
x = 96 ounces

6 pints = 96 ounces > 60 ounces
Therefore, 6 pints equal to more than 60 fluid ounces

A developer wants to enclose a rectangular grassy lot that borders a city street for parking. If the developer has 220 feet of f

MrRa [10]

Answer:

6050 square feet

Step-by-step explanation:

Based on the diagram attached, the area which the available fencing can enclose will measure X x Y feet. As the total length of fencing available is 220 feet, the fenced perimeter must equal 220 feet

$Y + 2X = 220$

$Y = 220 - 2X$

Area of a rectangle is determined by multiplying the length of perpendicular sides:

$Area = X*Y$

$Area = X(220 - 2X)$

$Area = 220X - 2X^{2}$

The derivative of an equation determines the slope at any given point of that equation. At the maximum or minimum point of the equation, the slope will be zero. Therefore, differentiating the equation for area and equating it to zero will give the value of X where the area is maximum.

A simple variable can be differentiated using below concept:

$f(a) = a^{b}$
