Answer:
XY = 18
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
10 XY = 180 ( divide both sides by 10 )
XY = 18
Given that,
Shelley's pet food store sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20.
For peanut, the cost is ratio is
For beef, the ratio is
If we take cross product of these items,
It implies, that the sale is in true proportion. From the cross product, we find that it is equal.
We know that the formula for the volume of a box is:
Where:
l = length
w = width
h = height
The formula of the surface area of a box is:
Based on the given we know the following:
and
If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:
Let:
l = 6cm
w = 7cm
h = 13cm
Now let's try this on the surface area formula:
The answer is then:
l = 6cm
w = 7cm
h = 13cm
Any order would be fine.
