Notice that we can calculate the area of the square and the rectangle separately to get the following:

\begin{gathered} A_1=3\cdot3=9in^2 \\ A_2=9\cdot2=18in^2 \\ \Rightarrow A=A_1+A_2=9+18=27in^2 \end{gathered}

therefore, the total area is 27 in^2

Last year Billy weighed 75kg. This year he weighed 90kg. With what percentage did his weight increase. SHOW ALL WORK!!!
polet [3.4K]

well let's round. 90= 100, 75=80 that is how I face it. now 80 is 1/5 of 5/5= 100. so as a (%) we would sort it like:::: it is 80% out of +100 so he must have grown around 13%-16% due to him being 75kg in the past.

Which of the following correctly uses absolute value to show the distance between −50 and 12?
Softa [21]

Answer:

 62 units

Step-by-step explanation:

The absolute value of a number A is the positive distance between 0 and the number A (you can think this distance as the distance measured with a ruler from 0 to the number). For example:

|-2|=2 ,  |25|=25,  |-3|=3, |-25.3|=25.3

Note that the absolte value is always positive.

The distance between two numbers P,Q in the real line is the absolute value of the difference between the two points:

Hence, the distnce between P=-50 and Q=12 is equal to

Your local volunteer group is making t-shirts. The shirt printers charge $35 to make the first t-shirt and $11 to make each addi
mylen [45]

We are to find the number of t-shirt the group can buy given $250

Cost of first t-shirt = $35

<em>Cost of each additional t-shirt</em> = $11

<em>Total amount with the group</em> = $250

<em>number of t-shirt the group can buy</em> = x

The equation:

<em>250 = 35 + 11x</em>

250 - 35 = 11x

215 = 11x

divide both sides by 11

x = 215/11

x = 19.5

The group can not buy a decimal number of t-shirt.

x will be rounded down to 19

Therefore,

the total number of t-shirt the group can buy is 1 + 19

= 20 t-shirt
