noname [10]

Solution

Question 1:

- Use of the area of squares to explain the Pythagoras theorem is given below

- The 3 squares given above have dimensions: a, b, and c.

- The areas of the squares are given by:

$\begin{gathered} \text{For square of length }a\to a^2 \\ \text{For square of length }b\to b^2 \\ \text{For square of length }c\to c^2 \end{gathered}$

- The Pythagoras theorem states that:

"The sum of the areas of the smaller squares add up to the area of the biggest square"

Thus, we have:

$c^2=a^2+b^2$

Question 2:

- We can apply the theorem as follows:

$\begin{gathered} 10^2+24^2=c^2 \\ 100+576=c^2 \\ 676=c^2 \\ \text{Take square root of both sides} \\ \\ c=\sqrt[]{676} \\ c=26 \end{gathered}$

Thus, the value of c is 26

Find the least common multiple of these two expressions. 15x^7y^3u^8 and 6y^4u^5

snow_tiger [21]

Answer:

$30x^7y^4u^8$

Step-by-step explanation:

We have been given two expressions $15x^7y^3u^8$ and

$6y^4u^5$

Now we need to find out least common multiple of these two expressions.

First we need to find out what is common factor of both expressions. $15x^7y^3u^8$ and

$6y^4u^5$

Least common multiple means find the expression which can be divided by both expressions.

15 and 6 both goes into 30

so 30 is part of LCM (least common multiple )

Now pickup the highest exponent of each variable.

So we get $x^7y^4u^8$

Hence required least common multiple is $30x^7y^4u^8$

Simon and Andrew see a speed limit sign that says 65 kilometers per hour. They decide to convert this speed limit to miles per h

stealth61 [152]

Answer:

40.38912735 or about 40 miles per hour (rounded to the nearest whole number)

Step-by-step explanation:

1.) You want to convert kilometers per hour to miles per hour.

2.) There are 0.62137119 miles in 1 kilometer.

3.) Multiply 65 by 0.62137119

4.) That equals 40.38912735

5.) This answer can be rounded to 40 mph.

Find the product.

natka813 [3]

Answer:

C:) 17/3

Step-by-step explanation:

Simplify the following:

((3 + 2/5)×5)/3

((3 + 2/5)×5)/3 = ((3 + 2/5)×5)/3:

((3 + 2/5)×5)/3

Put 3 + 2/5 over the common denominator 5. 3 + 2/5 = (5×3)/5 + 2/5:

((5×3)/5 + 2/5 5)/3

5×3 = 15:

((15/5 + 2/5)×5)/3

15/5 + 2/5 = (15 + 2)/5:

((15 + 2)/5×5)/3

15 + 2 = 17:

(17/5×5)/3

17/5×5 = (17×5)/5:

((17×5)/5)/3

((17×5)/5)/3 = (17×5)/(5×3):

(17×5)/(5×3)

(17×5)/(5×3) = 5/5×17/3 = 17/3:

Answer: 17/3
