Circle X with a radius of 6 units and circle Y with a radius

Mathematics
1 answer:
asambeis [7]3 years ago

Answer:

Option C.

Step-by-step explanation:

It is given that radius of circle X is 6 units and radius of circle Y is 2 units.

Here, circle Y is smaller and circle X is larger.

\text{Scale factor}=\dfrac{\text{Radius of circle X}}{\text{Radius of circle Y}}

\text{Scale factor}=\dfrac{6}{2}

\text{Scale factor}=3

If we translate the circles so they share a common center point, and after that we dilate circle Y by a scale factor of 3, then we get circle which is equal to circle X.

We know that, after dilation the figure and its image are similar.

Hence, we can say that both circles are similar.

Therefore, the correct option is C.

Vinil7 [7]

The total cost that will be paid by the family will be RM(15x - y).

<h3>How to calculate the cost?</h3>

The entrance fee to a circus for a child is RM(3x-y).

The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.

Therefore, the cost for 2 adults and three children will be:

= 2(3x + y) + 3(3x - y)

= 6x + 2y + 9x- 3y

= 15x - y

Ralph buys a desk that regularly sells for $250 and a desk chair that regularly sells for $145. both items are on sale at 15% of
Lunna [17]
C) (0.85 + x/100)(250+145) does not give the correct answer.

Explanation
A) works; adding the two costs together is 250+145=395.  We multiply this by 0.85 because 100%-15%=85%=0.85.  We also have x% tax, which is represented by x/100, added to 100% of the value, or 1.00.  Altogether this gives us 
395(0.85)(1+x/100) = 395(0.85 + (0.85x/100)) = 395(0.85) + 395(0.85x/100)
= 395(0.85) + 395(0.0085x)
B) works; we have 250+145 for the original price; we have 85% = 0.85 of the value; we also have 100% + x%, which is (100+x)/100.
C) does not work; (0.85+x/100)(395) does not take into consideration that you are finding the tax after taking the 85%.  This will simplify out to
0.85*395 + (x/100)(395) = 335.75 + 395x/100 = 335.75 + 3.95x, which is too much.
D) works; simplifying the expression from A, we have 395(0.85) + 395(0.0085x) = 335.75 + 3.3575x.
