Answer:

62 feet

Step-by-step explanation:

Hi there,

Let's start the problem by figuing out the width of the rectangle.

let w = the width of the rectangle.

The formula for the area of a rectangle is A = l*w, so let's plug in what we know.

228 = 12w

Now, let's solve for w, the width, by dividing both sides by 12

w = 19; The width is 19 feet.

Now, we have our length, 12 feet, and our width 19 feet.

So, we should now use the formula for perimiter to find the perimiter of this rectangle. The formula is P = W + W + L + L

Let's plug in the numbers

P = 12 + 12 + 19 + 19

P = 62 feet

Hope this helps! Stay safe!

The Correct option is D). y=1x+1 And y=2x+2

Step-by-step explanation:

The equation of a line is given as y=mx+c.

where m=slope of line and c=y intercept

The slope of line is given as m= $\frac{(Y2-Y1)}{(X2-X1)}$

Solving for Redline:

From the given graph, redline passes through (-1,0) and (0,1)

The slope of Redline is m= $\frac{(Y2-Y1)}{(X2-X1)}$

The slope of Redline is m= $\frac{(1-0)}{(0-(-1))}$

The slope of Redline is m=(1)

And Y-intercept is 1

The equation of a Redline is given as y=1x+1

Solving for Blue-line:

From the given graph, Blue-line passes through (-1,0) and (0,2)

The slope of Blue-line is m= $\frac{(Y2-Y1)}{(X2-X1)}$

The slope of Blue-line is m= $\frac{(2-0)}{(0-(-1))}$

The slope of Blue-line is m=(2)

And Y-intercept is 2

The equation of a Blue-line is given as y=2x+2

The Correct option is D). y=1x+1 And y=2x+2

What is the area of an isosceles trapezoid, if its shorter base has length of 18 cm, the length of the altitude is 9 cm, and the

padilas [110]

The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).

Here, b = 18 cm and h = 9 cm. Thus, the desired area is:

(18 cm)(9 cm)

A = ----------------------- = 81 cm^2

This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.

4x+3y=6

sattari [20]

Answer:

Step-by-step explanation:

4x + 3y = 6

-4x + 2y = 14

0 + 5y / 5 = 20/ 5 = 4 = y

4x + 3(4) = 6

4x + 12 - 12 = 6 - 12

4x / 4 = -6 / 4 = -3 / 2 =x

Please Help ASAP!!! I'm Timed!!! Will give brainliest to first correct answer!!! Hurry!!

Answer: If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the upper quadrants, then the reflection would be negative for x.

If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the lower quadrants, then the reflection would be negative for y.

This is because the lower quadrants are usually negative and the upper quadrants are usually positive according to the x axis. The same thing vice verse with y.

These are the rules that I’m guessing your trying to find. Hope this helps!

Hello! Please help.

3 cups left.

David biked a total of 158 miles (option C)

Why?

- First exercise:

To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.

So, calculating we have:

$TotalMuffins=24=4*6\\\\UsedCups=\frac{1}{2}*4=2Cups$

We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.

$CupsLeft=5cups-2cups=3cups$

Hence, there are 3 cups left.

- Second exercise:

We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.

So, calculating we have:

$FirstDay=10miles*2=20miles\\SecondDay=10\frac{1}{2}miles=10.5miles\\ThirdDay=11miles*3=33miles\\FourthDay=11\frac{1}{2}miles*4=11.5miles*4=46miles\\FifthDay=12miles*3=36miles\\SixthDay=12\frac{1}{2}miles=12.5miles$

$Total=20miles+10.5miles+33miles+46miles+36miles+12.5miles\\Total=158miles$

Hence, we have that David covered a total 158 miles. (Option C)

Have a nice day!
