Area of the base = 8^2 = 64

area of 1 traingle = 1/2 * 8 * 5.4 =  21.6

there are 4 triangular sides  so their area = 4 * 21.6  = 86.4

Total surface area = 64 + 86.4 =  150.4 cm2

german
You need to set up a portportation to solve this question to do so you need to know that 3 tenths is 30% so you can do:

30/100 = x/1.7

So now you cross multiply doing 30X17=510
Finially X=510/100
Simpified Answer is 5.1 liters

bixtya [17]
<h3><em>Hey! </em></h3>

<u>let the numbers be n and m</u>

<u>n+m=65</u>

<u>n=4m</u>

<em>So when we put our work in:</em>

<u>4m+m=65</u>

<u>5m=65</u>

<u>m=13</u>

<u>n=52</u>

So therefore your two numbers are 52 and 13!

<em>Hope this helped! °ω°</em>

Answer:

y=3r+5

Step-by-step explanation:

Break up the sentance.

Capon city has 5 more than 3 times as many residents as harbor city.

The sentance above can be written like this: y=5+3x. Since they want r to represent the number of people in Harbor city, use r in place of x.

Capon city=y

has=equal sign

5 more=+5

3 times as many=3r

y=3r+5
