Answer:

4 gallons

Step-by-step explanation:

First find the area of the deck

A = l*w

42 * 28 =1176 ft^2

Divide the area by 350 ft^2 per gallon

1176/350 =3.36

We need to buy full gallons so we round up

4 gallons

Answer:

The solution to the system of equations be:

$x=3,\:y=-1$

Hece, option B is correct.

Step-by-step explanation:

Given the system of equations

$\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}$

Multiply x − 3y = 6 by 2: 2x-6y=12

$\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}$

$2x+2y=4$

$-$

$\underline{2x-6y=12}$

$8y=-8$

so the system of equations becomes

$\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}$

Solve 8y = -8 for y

$8y=-8$

Divide both sides by 8

$\frac{8y}{8}=\frac{-8}{8}$

$y=-1$

$\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1$

$2x-6\left(-1\right)=12$

$2x+6=12$

subtract 6 from both sides

$2x+6-6=12-6$

$2x=6$

Divide both sides by 2

$\frac{2x}{2}=\frac{6}{2}$

$x=3$

Therefore, the solution to the system of equations be:

$x=3,\:y=-1$

Hence, option B is correct.

Which represents the number of times all outcomes less than a given outcome occur? cumulative frequency relative frequency frequ

max2010maxim [7]

Answer: cumulative frequency

Step-by-step explanation:

A frequency is the number of times a data value occurs.
A relative frequency is the fraction or proportion of times an answer occurs.

The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.

In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.

Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.

kipiarov [429]

Answer:

Step-by-step explanation:

L=4W+8

P=2(L+W)

P=2(5W+8) and P=476

2(5W+8)=476

5W+8=238

5W=230

W=46yds

L=4(46)+8=192yds

So the dimensions are 46X192 yards
