A right triangle has a hypotenuse of 10 feet and a leg of 6 feet. What is the length of the other leg?
Artemon [7]

Answer:

The other length of the leg is <em>8 feet.</em>

Step-by-step explanation:

To find the answer we have to find what<em> 10</em> and <em>6 is squared.</em>  <em>10 x 10 = 100</em>.  

<em>6 x 6 = 36.  </em>Now since we are trying to find the length of the other leg, we will <em>subtract 100 from 36</em> and we get <em>64</em>.  Then for the last step, we will figure out what number<em> squared equals 64.</em>  Because 8 x 8 = 64, <em>8 is our answer.</em>

Translate each sentence into a formula
Bas_tet [7]
1) Perimeter=2length+2width
This is the formula for finding the perimeter of a rectangle

2) Density=mass/volume
The “Quotient” is the answer to a division problem (like how the “sum” is the answer to an addition problem) which is why we know to divide mass and volume

3) Force = mass*acceleration
The “product” is the answer to a multiplication problem which is why we know to multiply mass and acceleration

4) surface area = 6*L^2
The formula used to calculate the area of a square is L^2. The problem tells us that surface area is the sum of all the faces of a 3D shape. Because there are 6 sides on a cube, we multiply L^2 by 6.

Hope this helps!

Answer:

<h3>              1)   7x - 5 </h3><h3>              2)   9y - 18 </h3><h3>              3)   0.5n + 4n </h3><h3>              4)  2(w³+23)</h3><h3> Step-by-step explanation:</h3>

1)

The product of seven and a number x:   7·x = 7x

<u>Five less than the product of seven and a number x:</u>

<h3>7x - 5 </h3>

2)

nine times a number y:  9·y = 9y

<u>The difference of nine times a number y and eighteen:</u>

<h3>9y - 18 </h3>

3)

half a number n:   0.5n

four times the number:   4·n = 4n

<u>Half a number n increased by four times the number:</u>

<h3>0.5n + 4n </h3>

4)

a number w cubed:  w³

the sum of a number w cubed and twenty-three:  w³+23

<u>Twice the sum of a number w cubed and twenty-three:</u>

<h3>2(w³+23)</h3>
