The area of the sandbox is 56 2/3 square feet. The width is 8 1/2 feet. What is the length? Hint: Divide area by length
sertanlavr [38]

Answer:

20/3 ft or 6 2/3 ft

Step-by-step explanation:

A = 56 2/3 sq ft

W = 8 1/2 ft

L = ?

A = LW

L = A/W

L = \dfrac{A}{W}

L = \dfrac{56~\frac{2}{3}~sq~ft}{8~\frac{1}{2}~ft}

Change the mixed numbers into fractions.

a\frac{b}{c} = \dfrac{ac + b}{c}

L = \dfrac{\frac{56 \times 3 + 2}{3}}{\frac{8 \times 2 + 1}{2}}

L = \dfrac{\frac{170}{3}}{\frac{17}{2}}

L = \dfrac{170}{3} \div \dfrac{17}{2}

L = \dfrac{170}{3} \times \dfrac{2}{17}

L = \dfrac{170 \times 2}{3 \times 17}

L = \dfrac{17 \times 10 \times 2}{3 \times 17}

L = \dfrac{10 \times 2}{3}

L = \dfrac{20}{3}

Answer: 20/3 ft or 6 2/3 ft

What doubles fact can help you solve 6+5=11?
kotykmax [81]
The correct answer is this one: "C. 5+5=10 "

From the equation 6 + 5 = 11
We can have the doubles : 5 + 5 + 1 = 11
<span>The doubles plus one are the facts in which one addend is larger than the other by one.</span>

Here are the choices.

A-  8+8=16 B-  7+7=14
C-   5+5=10 D-   4+4=8

The midpoint of line segment AB is (-2,1). If the coordinates of B are (0,2) what are the coordinates of A?
Whitepunk [10]

The required coordinate of A will be at (-4, 0)

When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;

M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ] where:

X =\frac{x_2+x_1}{2} \\Y=\frac{y_2+y_1}{2}

From the question, we are given the following coordinate points

X=-2\\x_1=0\\

Get x₂;

X =\frac{x_2+x_1}{2}\\-2 =\frac{x_2+0}{2}\\2 \times -2=x_2+0\\-4=x_2\\ Swap\\x_2=-4\\

Get y₂;

Y =\frac{y_2+y_1}{2}\\1 =\frac{y_2+2}{2}\\2 \times 1=y_2+2\\2=y_2+2\\y_2=2-2\\y_2=0

Hence the coordinate of A will be (-4, 0)
