Step-by-step explanation:

$\frac{20}{48} \times \frac{80}{44}$

Divide the fraction with 4

$\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12} \times \frac{20}{11}$

Reduce the number with factor 4

$\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3} \times \frac{5}{11}$

Multiply the fractions

$\frac{5 \times 5}{3 \times 11} = \frac{25}{33}$

$\boxed{\green{= \frac{25}{33} = 0.75}}$

You have 42 ft. of fencing (1 ft. segments) to make a rectangular garden. How much should each side be to maximize your total ar

Verizon [17]

Answer:

$Length=10.5\ ft$

$Width=10.5\ ft$

$Area=110.25\ ft^{2}$

Step-by-step explanation:

Let

x----> the length of the rectangular garden

y---> the width of the rectangular garden

we know that

The perimeter of the rectangle is equal to

$P=2(x+y)$

we have

$P=42\ ft$

$42=2(x+y)$

simplify

$21=(x+y)$

$y=21-x$ ------> equation A

Remember that the area of rectangle is equal to

$A=xy$ ----> equation B

substitute equation A in equation B

$A=x(21-x)$

$A=21x-x^{2}$ ----> this is a vertical parabola open downward

The vertex is a maximum

The y-coordinate of the vertex is the maximum area

The x-coordinate of the vertex is the length side of the rectangle that maximize the area

using a graphing tool

The vertex is the point $(10.5,110.25)$

see the attached figure

$x=10.5\ ft$

Find the value of y

$y=21-10.5=10.5\ ft$

The garden is a square

the area is equal to

$A=(10.5)(10.5)=110.25\ ft^{2}$ ----> is equal to the y-coordinate of the vertex is correct

Explain how you know that the some of 12.6, 3.1, and 5.4cis greater than 20

ddd [48]

You can add the numbers together so:

12.6
3.1
+ 5.4
 21.1

Since the sum of the numbers is 21.1, it is greater than 20
