So basically the side length went from 3 to 7.5, so we have to find the factor which caused the increase. We have to find what times 3 makes 7.5

So our equation is 3×x=7.5
From here on it's just algebra, we'll divide each side by 3 to isolate x

7.5/3=2.5
x=2.5
So the scale factor applied to the first rectangle is 2.5

A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. What
OverLord2011 [107]

Answer:

30%

Step-by-step explanation:

Well since we know that 45% is vanilla that means we have part of our answer

Also we know we sold 1/4 strawberry which in percent that would be 25%

If we add 45% with 25%  45+25=70 then since something can only be 100%

100%-70%=30%

you sold 30% chocolate

A plumber has a 2.5 metre long copper pipe
Anastaziya [24]

We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left
