Emily has a rectangular deck in her backyard with an area of 96 square feet. She wants to increase.

Dominik [7]

Answer:

The area of the deck after she doubles the length and width will be of 384 square feet.

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle of length l and width w is given by:

$A = lw$

Doubling length and width:

If we double the length and the width, the dimensions are 2l and 2w. Thus, the area will be of:

$A_d = 2l*2w = 4lw$

That is, if both dimensions are doubled, the area is multiplied by 4.

What will the area of the deck be after she doubles the length and width?

Was 96. Then, both dimensions were doubled, and the area has to be multiplied by 4.

96*4 = 384

The area of the deck after she doubles the length and width will be of 384 square feet.

What percent of 75 is 24?

Scilla [17]

Answer:

<h2>Your Answer is 32%</h2>

Explaination:

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 >> Y = 24

75

STEP 2 >>

24 × 100 = 32

75 × 100 100

STEP 3>> Y = 32%

Finally, we have found the value of Y which is 32 and that is our answer.

You can use a calculator to find what percent of 75 is 24, just enter 24 ÷ 75 × 100 and you will get your answer which is 32.

Square Root

Oxana [17]

Answer:

1). $(x+\frac{1}{4})^{2}=\frac{4}{9}$

2). $x+\frac{1}{4}=\pm \frac{2}{3}$

Step-by-step explanation:

Here the given equation is $x^{2}+\frac{1}{2}x+\frac{1}{16}=\frac{4}{9}$

We have to factor the perfect square trinomial on the left side of the equation

So left side of the equation is $x^{2}+\frac{1}{2}x+\frac{1}{16}$

= $x^{2}+2\times \frac{1}{4}x+(\frac{1}{4})^{2}$

$=(x+\frac{1}{4})^{2}$ since [(a+b)²= a²+b²+2ab]

Therefore the factorial form of the equation will be

$(x+\frac{1}{4})^{2}=\frac{4}{9}$

Now we have to solve the equation by applying square root property

$\sqrt{(x+\frac{1}{4})^{2}}=\sqrt{\frac{4}{9}}$

$x+\frac{1}{4}=\pm \frac{2}{3}$

Adam tried to compute the average of his 6 test scores. he mistakenly divided the correct sum of all of his test scores by 5, wh

kipiarov [429]

Sum/5 = 90
so Sum = 450 which should be divided by 6
450/6 = 75 as the real average.
