Answer:

b = 4

Step-by-step explanation:

a^2 + b^2 = c^2

a = 3

b = b

c = 5

a^2 + b^2 = c^2

(3)^2 + b^2 = (5)^2

9 + b^2 = 25

b^2 = 25 - 9

b^2 = 16

√b^2 = √16

b = 4

REY [17]

Answer:

$\frac{82}{10}$

Step-by-step explanation:

$1\frac{1}{5} +\frac{17}{2} -\frac{3}{2}$

→ Convert the mixed number into an improper fraction

$\frac{6}{5} +\frac{17}{2} -\frac{3}{2}$

→ Complete the takeaway operation

$\frac{6}{5} +\frac{14}{2}$

→ Make the denominators the same

$\frac{12}{10}+\frac{70}{10}$

→ Simplify

$\frac{82}{10}$

What is the length of HG?

Leviafan [203]

Answer:

$HG = 5$

Step-by-step explanation:

Given

$HE = 8mm$

$EF = 12mm$

$Area = 68mm^2$

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>

In this case;

$Area = \frac{HG + EF}{2} * HE$

Substitute the values of Area, HE and EF

$68 = \frac{HG + 12}{2} * 8$

$68 = (HG + 12) * 4$

Divide both sides by 4

$\frac{68}{4} = \frac{(HG + 12) * 4}{4}$

$17 = HG + 12$

Subtract 12 from both sides

$17 - 12 = HG + 12 - 12$

$5 = HG$

$HG = 5$

<em>Hence, the length of HG is 5mm</em>

Rob is saving to buy a new MP3 player. For every $15 he earns babysitting, he saves six dollars. On Saturday, Rob earned $75 bab

nikitadnepr [17]

If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
