Marcy’s breakfast table has a square table top with an area of 36 square feet. What is the approximate diagonal length of the table top? Round to the nearest tenth.

Answers

Answer 1

Answer:

8.5 ft = length of diagonal

Step-by-step explanation:

If A = 36 ft^2, then s (length of one side) = 6 ft.

The diagonal and any one side create a 45 degree angle.  

sin 45 degrees = (length of side opposite the 45 degree angle)/hypotenuse

                                                          6 ft            6√2 ft          

Then (length of hypotenuse) = ------------------ = ---------------

                                                      sin 45 deg            1

This works out to 8.5 ft = length of diagonal

At last week's track meet, Stacy ran 9/12 of a km, Jules ran 4/5 of a km, and Raul ran 3/4 of a mile. Which two students ran the same distance?

Answers

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran [tex]\frac{9}{12}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km[/tex]

Jules ran [tex]\frac{4}{5}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{4}{5}=0.8\ km[/tex]

Raul ran [tex]\frac{3}{4}[/tex] of mile i.e.

[tex]\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km[/tex]

So, no two students ran the same distance.

WHAT IS THE SLOPE (NEED HELP DROM A PRO)
WILL MARK BRAINIEST IF ANSWER IS CORRECT AND EXPLAINED WELL

Answers

Hi!

So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.

Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).

Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.

Answer:

x = 8 , ∠ B = 70°

Step-by-step explanation:

∠ A and ∠ B are alternate exterior angles and are congruent, that s

8x + 6 = 4x + 38 ( subtract 4x from both sides )

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°

1. 10% of ________-8
2.28 is 4% of _________
3.25% of ________
4.13% of______
5.15 is 12.5% of _____​

Answers

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

 

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.
