Answer:
value of sides YZ is 36 cm
Step-by-step explanation:
Similar triangles states that the length of the corresponding sides are in proportion.
Given that: ΔABC is similar to ΔXYZ
then;
Corresponding sides are in proportion i.e
.....[1]
As per the statement:
side AB = 6 cm, side BC =18 cm and side XY = 12 cm.
Substitute these in [1] to solve for side YZ;

or

By cross multiply we have;
cm
Therefore, the value of sides YZ is 36 cm
<h3>
Answer: 6 apples</h3>
x = number of apples originally
50% of x = 0.50*x = amount of apples eaten = 3
0.50x = 3
x = 3/0.50 ....... divide both sides by 0.50
x = 6
You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.
Conversion from gallons to quarts
1 gallon = 4 quarts
Now,
Angela has

gallons =

= 10 quarts of blue paint
Ryou has 1/2 of what Angela has = 1/2*10 = 5 quarts of white paint.
Each wall requires

of paint.
After coloring;
Blue colored walls = (10)/(

) = 3 walls with 7/11 quarts of paint remaining.
White colored walls = (5)/(

) = 1 wall with 9/11 quarts of paint remaining
