−2/3)
Answer:
#1: 15
#2: 5
Step-by-step explanation:
#1 explanation
a^2+b^2=c^2
12^2+9^2=c^2
We are trying to find the hypotenuse (the slanted side)
144+81=c^2
225=c^2
The square root of 225 is 15
#2 explanation
a^2+b^2=c^2
12^2+b^2=13^2
We need to find one of the leg(s)
144+b^2=169
169-144=25
25=b^2
Square root of 25 is 5

Answer:
31
Step-by-step explanation:
Here the trick is to perform the indicated operations in the correct order. Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.
Doing the work inside parentheses first:
(3 × 22) ÷ 6 + [28 – (4)2] => (66) ÷ 6 + [28 - 8], or
(66) ÷ 6 + [28 - 8] => 11 + [20], or 31
Step-by-step explanation:
Pam and Erin want the gardens to be proportional.
<em>proprtional</em><em>-</em><em> </em><em>equal</em><em> </em>
Pams garden has a length of 16 and width of 12. To find the area of Pam's garden multiply the length by the width.
<em>16</em><em>×</em><em>12</em><em>=</em><em> </em><em>192</em><em> </em>
Now that we know the area of Pam's garden, we can set up and equation for Erin's garden. Since they have to be equal we know that Erin's garden should equal 192. Thus we solve for the length by dividing the width from the total.
<em>192</em><em>÷</em><em>21</em><em>=</em><em>9.14</em>
