50% of all the cakes Lucy bakes that week were party cakes: one fifth were fruit cakes and the remainder were sponge cakes. What percentage of cakes were sponge cakes ?

Answers

Answer 1
Answer: 50% is equal to 5/10 so 5/10 were party cakes 1/5x2=2/10 so 2/10 were fruit cakes 5/10+2/10=7/10 so 10/10 which is 100% of all cakes 10/10-7/10=3/10 so 3/10 of the cakes were sponge cakes.

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point of symmetry? True or false?

Answers

False.

Reflectional symmetry, as the name suggests, is a property a design has if it maintains all characteristics when it is reflected with respect to some axis. This means that you must choose a line, and make it act as a mirror.

For example, you can consider a square, and one of its diagonal. If you "flip" the figure with respect to said diagonal, the square will remain the same.

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about a line of symmetry so the given statement is False.

What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will bit that (x,y) → (y,x).

If we want to reflect any graph or curve then we need to take a reference axis or line.

If the line is a line of symmetry then the length, with and remaining gall characteristics will remain the same.

Thus, the reflection must be the point of the axis.

Hence "The preceding statement is False because reflective symmetry is the property that a design possesses if it retains all attributes when it is rotated about a line of symmetry".

(5 × 4) + (7 × 9)
20 + 63
= 83

or

73 + 92 + 54 + 96 × 6

(73 + 92) + (54 + 96) × 6

165 + 150 × 6

Step-by-step explanation:

From the question, Paloma added a garden to her painting. She has 12 rows of flowers and each row has 13 plants in it while each plant has 15 flowers on it. To calculate the number of flowers in Palomas garden, we multiply the number of rows by the total number of plants and the number of flowers in each plant. This will be:

= 12 × 13 × 15

= 2340 flowers

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service charges. Company B charges $5 per window and an additional $15 as service charges.Part A: Write equations to represent Company A's and Company B's total charges for cleaning a certain number of windows. Define the variable used in the equations. (4 points)

Part B: Which company would charge less for cleaning 8 windows? Justify your answer. (3 points)

Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows? (3 points)

Answers

Part A
y=6x+12
y=5x+15
x is the amount of windows, y is the total amount of money 
Part B
y=6(8)+12       =60
y=5(8)+15      =52
Company B 
Part C
y=6(6)+12       =48
y=5(6)+12       =42
$6 is saved
