A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. How many inches of frame will she need? Round to the nearest inch.

Answers

Answer 1

Answer: The square has a diagonal of 44 inches.
In order to get the side, we need to use the pythagorean equation.

Diagonal (d) ^ 2 = side^2 + side ^ 2
Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2
44^2 = 2s^2
1936 = 2s^2
2s^2 = 1936
s^2 = 968
s = 31.11 inches

The length of the side is approximately 31 inches.
Perimeter = 4*s
Perimeter = 4 * 31
Perimeter = 124 inches

So she need a total of 124 inches to frame the square.

Answer 2

Answer:

I am sure the anwser is 124in

I hope this helps let me know! ;)

Which equation is related to the equation shown?x + 3 = 12

A.

x = 12 + 3

B.

x = 12 ÷ 3

C.

x = 12 − 3

D.

x = 12 • 3

Answers

The answer is:

C) x = 12 - 3

Work/explanation:

To solve, subtract 3 on each side:

$\rightarrow\hspace{13} \sf{x+3 = 12}\n\n\n\rightarrow\hspace{13}\sf{x=12-3}\n\n\n\rightarrow\hspace{13}\sf{x=9}$

The equation that is related to the equation shown is x = 12 - 3.

C, because it's the opposite of the actual equation.

Given: -1/2x > 6.Choose the solution set.
{x | x R, x > -12}
{x | x R, x < -12}
{x | x R, x > -3}
{x | x R, x < -3}

Answers

Answer:

{x | x R, x<-12}

Step-by-step explanation:

SO basically think of it as x is a teenager that wants to be alone. so have to figure out how to get everyone on the otehr side of their bedroom door (>)

so you are going to do this

-1/2x>6

/-1/2x /-1/2x

x<6/-1/2

x<6*-2/1

x<-12

The correct way to write 1/4% as a decimal is 0.0025.

The reporter's likely error was that he did not notice the percent sign, thus saying that 1/4% is equivalent to 0.25.

Answer:

a. .0025 b. (see below)

Step-by-step explanation:

Percents are converted to decimals by moving the decimal 2 places to the left.

a. Write 1/4% as .25% Then, move the decimal two places to the left. You arrive at .0025.

b. The reporter's likely error is he/she thinking that 25 being 1/4 of one hundred, but it is not 1/4 percent of one hundred. It is 25% of one hundred.
