ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger roots is G G, and Ray has a coupon for 1
2 answers:
Answer: 0.9 is the decreasing factor.
Step-by-step explanation:
Here, The price of the ginger roots is G .
And, It there occurs the 10% off on this amount then,
The new price of the ginger is 90% of G.
That is, Final price of G =
=
= 0.9G
Since, 0.9 decreases the price of the ginger.
Therefore, It is called decreasing factor for the function which represents the price of the ginger.
Answer:
0.9 represents percent of the original price, G, as decimal that Ray pays for the ginger roots.
Step-by-step explanation:
We have been given that the price of the ginger roots is G. Ray has a coupon for 10% off. The expression represents the price Ray pays for the ginger roots after using the coupon.
Since Ray has a coupon 10% off, so the price of the ginger roots will be 90% of G as 100% minus 10% equals 90%.
0.9 represent 90% of G that is:
Therefore, 0.9 represents percent of the original price, G, as decimal that Ray pays for the ginger roots.

The distance of the road junction form Timpson is given as 21.57 miles.
<h3>We have to solve this using the Pythagoras theorem method</h3>We have AT =
√60² + 12² = 12√26
∠TMG = LN = 90 degrees
Therefore we have the system
When we cross multiply we would have to solve for TM
TM = 21.57 miles
Hence the distance of the road junction form Timpson is given as 21.57 miles.

We call:
T = Tom's paiting rate
G = George's paiting rate
M = Mario's paiting rate
As the first statement says that they can work together, then:
T + G + M = Painting rate working together, that is the surface area they paint per hour.
Since the problem says that they last four hours painting a
room, then we need to multiply the amount of hours times the painting rate that is equal the surface area of the room, so:
4(T + G + M) = 600
Applying a similar reasoning, the George and Mario's painting rate is:
0 + G + M
Note that 0 implies that Tom didn't work in this case.
As they last eight hours painting the room, then:
8(0 + G + M) = 600
The same reasoning is applied to Tom and George working together. In this case 0 implies that Mario didn't work, so:
6(T + G + 0) = 600
We have a system of linear equations in three variables T, G, M:
<span>4(T+G+M)=600
8(0+G+M)=600
6(T+G+0)=600
</span>
Solving:
(1) T + G + M = 150
(2) G + M = 75
(3) T + G = 100
Substitute (3) in (1):
100 + M = 150 ∴ M = 50
Replace M in (2):
G + 50 = 75 ∴ G = 25
Substitute G in (3)
T + 25 = 100 ∴ T = 75
Then, the painting rates are:
Tom = 75
George = 25
Mario = 50
<span>Solving for Time to determine how long it would take Tom to paint the room alone:

<span>Painted Area = Painting Rate×Time, so:
