I need help with this Pythagorean Theorem word problem

frez [133]

Answer:

10.63.

Step-by-step explanation:

First we need to understand pythagorean theorem that is,

Hypotenuse^2=perpendicular^2+base^2.

=7^2+8^2.

=49+64

=113.

Hypotenuse^2=113.

Square root both sides.

Hypotenuse=10.63.

Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into p

love history [14]

Answer:

Step-by-step explanation:

Length of one of the boards = 8 feet

Converting to inches

$1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}$

One cut is 16 inches

So, we divide the length of the board by 16

$\dfrac{96}{16}=6$

So, one board is cut into 6 pieces.

The other board is also 8 feet long.

So, the number of pieces the other board is cut into is also 6.

Hence, a total of $6+6=12$ pieces of each 16 inches long can be cut from the two boards.

A cube had a volume of 1/512 cubic meter. What is the length of each side of the cube using the formula "volume=Length×Width×Hig

MrRa [10]

Answer:

The length of each side of the cube is $\frac{1}{8}\ m$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=LWH$

but remember that in a cube

Length, width and height have the same value

Let

b-----> the length side of the cube

$L=W=H=b$

substitute in the formula

$V=(b)(b)(b)=b^{3}$

In this problem we have

$V=\frac{1}{512}\ m^{3}$

substitute and solve for b

$b^{3}=\frac{1}{512}$

$b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m$

therefore

The length of each side of the cube is $\frac{1}{8}\ m$

Can someone please answer this multiple choice questions numbers 2 , 12 and 13 please answer and please please show work

Vinil7 [7]

Answer:

2) D

12) C

13) D

Step-by-step explanation:

2) 4° C at 6:00 PM

A) + 2° - 6° = - 4° 4° - 4° = 0° 0° does not equal 4° A $\neq$ Correct

B) - 5° + 1° = - 4° 4° - 4° = 0° 0° does not equal 4° B $\neq$ Correct

C) + 6° - 4° = + 2° 4° + 2° = 6° 0° does not equal 4° C $\neq$ Correct

D) - 7° + 7° = 0° 4° + 0° = 4° 4° does equal 4° D = Correct

The answer to question #2 is D

12) M = -3

N ----> M = 8.5 units

The only possible options for N are:

-3 + 8.5 = 5.5

-3 - 8.5 = -11.5

-11.5 is not a choice, so the answer to question #12 is C

13) Scale: 1 inch = 70 yards

Abe walks 3.5 inches (on the diagram)

Multiply both sides of the scale by 3.5

3.5 * 1 inch = 70 * 3.5

3.5 inches = 245 yards

Abe walked 245 yards

The answer to question #13 is D

Hope this helps :)
