Using the Pythagorean Theorem, it is found that the length of the diagonal of the square shown below is given by:
F. [tex]h = 7\sqrt{2}[/tex]
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem, the diagonal is the hypotenuse, while the legs are the sides of [tex]l_1 = l_2 = 7[/tex], hence:
[tex]h^2 = l_1^2 + l_2^2[/tex]
[tex]h^2 = 7^2 + 7^2[/tex]
[tex]h^2 = 2 \times 49[/tex]
[tex]h = \sqrt{2 \times 49}[/tex]
[tex]h = 7\sqrt{2}[/tex]
Hence option F is correct.

How do you convert a repeating decimal into a fraction? Because, I was asked this question: Rewrite as a simplified fraction. 3.24=?
Answer:
3 6/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
3.24=3.24/1
Multiply to remove 2 decimal places. you multiply top and bottom by 10^2 = 100
3.24/1×100/100=324/100
Find the Greatest Common Factor of 324 and 100. reduce the fraction by dividing both numerator and denominator by GCF = 4,
324÷4 over 100÷4=81/25
Simplify the improper fraction

Chandler is on a hike in the woods. He has an altimeter with him, and Chandler uses it to measure his height above sea level at various points in his hike. He starts out at 120.4 meters above sea level, then hikes up an additional 850.0 meters to the crest of a hill. Chandler takes a break, then hikes down into a valley that is 430.7 meters below the crest. How far above sea level, in meters, is Chandler when he is in the valley?
Answer:
539.7 meters above sea level.
Step-by-step explanation:
Okay in order to solve this problem we can take it one step at a time. First, he starts at an altitude of 120.4 meters above sea level.
Then he hikes up an additional (meaning we add) 850.0 meters.
120.4 + 850.0 = 970.4
Next, Chandler hikes down (meaning we subtract) 430.7 meters.
970.4 - 430.7 = 539.7
Therefore, we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.
Answer:
539.7 meters above sea level.
Step-by-step explanation:
, he starts at an altitude of 120.4 meters above sea level.
he hikes up an additional ( add) 850.0 meters.
120.4 + 850.0 = 970.4
Chandler hikes down ( subtract) 430.7 meters.
970.4 - 430.7 = 539.7
we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.

A sealed rectangular container 4 cm by 8 cm by 16 cm is sitting on its smallest face. In this position the water level is 4 cm from the top. How many centimeters from the bottom will the water level reach if the container is turned and placed on its largest face?
Answer:
height of water in the container is 3 cm.
Step-by-step explanation:
Given;
A sealed rectangular container, measuring 4 cm by 8 cm by 16 cm
the height of the container is 16 cm, when filled with water at 4 cm level from the top, thus, the height of water in the container is (16 cm - 4cm) = 12cm
Volume of water in the container when it is sitting on its smallest face = 4 cm x 8 cm x 12 cm = 384 cm³
Volume of water in the container when it is sitting on its largest face = 8 cm x 16 cm x h
where;
h is height of water in the container
384 = 8 x 16 x h
384 = 128h
h = 384 / 128
h = 3 cm
Therefore, height of water in the container is 3 cm.

Choose the correct math expression for: 45 more than the difference of 35 and 13.
(35 - 13) - 45
(35 - 13) + 45
(35 + 13) + 45
Answer:
(35-13)+45
Step-by-step explanation:
The second expression because as the difference of 35 and 13 is 35-13, it cannot be the third one. As the first phrase says 45 MORE than the 35-13, we need to have +45 after, and the second equation has +45, so the second expression is true about the statement. Hope it helps!

Is the following statement a biconditional?
If Maura is going to the library, then she is bringing her favorite binder.
yes
no
This is a regular conditional expression because it is in the form "If P, then Q"
P = Maura is going to the library
Q = she is bringing her favorite binder
A biconditional is of the form "P if and only if Q"
The "if and only if" is the key phrase needed. It allows us to swap the positions of P and Q to say "Q if and only if P".
