The way to calculate the perimeter for this particular shape would be 3x15 being as there is three 15 inch sides and when we do the multiplication we get 45 so the perimeter is 45inches have a nice day and please mark brainliest

How would i find the volume
spin [16.1K]
Volume is actually pretty simple once you get the hang of it, it’s just Base x Width x Height. So I’m this problem, all you would have to do is multiply these numbers BUT since it’s a triangle you’re going to divide that by two. So… 12 x 7.5 x 10 = 900 and then we dive by 2. 450. Hope this helps :)

Is it easier to subtract when the number are write above and below each other explain
expeople1 [14]
Yes it is, due to the fact that you can see exactly what you are subtracting because they are directing above and below each other. In all forms of math we subtract this way for a better understanding of what's needed to be subtracted.

For a school fund raising project, Aiden and Jacob collected money in the ratio of 3.5 : 6.8. Jacob collected $115.50 more than
user100 [1]
X - the amount of money collected by Aiden
y - the amount of money collected by Jacob

Aiden and Jacob collected money in the ratio of 3.5 : 6.8.
\frac{x}{y}=\frac{3.5}{6.8} \\
6.8x=3.5y \\
x=\frac{3.5}{6.8}y \\ x=\frac{35}{68}y

Jacob collected $115.50 more than Aiden.
x+115.5=y \\
x=y-115.5 \\ \\
x=x \\
\frac{35}{68}y=y-115.5 \\
\frac{35}{68}y-y=-115.5 \\
\frac{35}{68}y-\frac{68}{68}y=-115.5 \\
-\frac{33}{68}y=-115.5 \\
y=-115.5 \times (-\frac{68}{33}) \\
y=238 \\ \\
x=y-115.5=238-115.5=122.5 \\ \\
x+y=238+122.5=360.5

The total amount of money they collected is $360.50.
