A photocopier increased the sides of a square in the ratio 4:5.

Mathematics
1 answer:
Svetach [21]3 years ago
4 0

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks:
asambeis [7]
y = 0.012x + 0.65<span><span><span>

Number of pages </span> <span>     50.00    </span><span>  100.00 </span><span>   150.00 </span> <span>   200.00 </span> </span> <span> <span>

x = number of pages
y = cost

intervals of x = 50 pages
intervals of y = 0.60
0.60 / 50 = 0.012

y = 0.012x + 0.65
