Given:
The number of red flowers =24
The number of white flowers = 18
As flowers divided equally.
![\begin{gathered} 24=4\times6 \\ 18=3\times6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2024%3D4%5Ctimes6%20%5C%5C%2018%3D3%5Ctimes6%20%5Cend%7Bgathered%7D)
The HCF ( highest common factor) of 24 and 18 is 6.
The largest number of group that can be created is 6.
Question:
A solar lease customer built up an excess of 6,500 kilowatts hour (kwh) during the summer using his solar panels. when he turned his electric heat on, the excess be used up at 50 kilowatts hours per day
.
(a) If E represents the excess left and d represent the number of days. Write an equation for E in terms of d
(b) How much of excess will be left after one month (1 month = 30 days)
Answer:
a. ![E = 6500 - 50d](https://tex.z-dn.net/?f=E%20%3D%206500%20-%2050d)
b. ![E = 5000](https://tex.z-dn.net/?f=E%20%3D%205000)
Step-by-step explanation:
Given
Excess = 6500kwh
Rate = 50kwh/day
Solving (a): E in terms of d
The Excess left (E) in d days is calculated using:
![E = Excess - Rate * days](https://tex.z-dn.net/?f=E%20%3D%20Excess%20-%20Rate%20%2A%20days)
The expression uses minus because there's a reduction in the excess kwh on a daily basis.
Substitute values for Excess, Rate and days
![E = 6500 - 50 * d](https://tex.z-dn.net/?f=E%20%3D%206500%20-%2050%20%2A%20d)
![E = 6500 - 50d](https://tex.z-dn.net/?f=E%20%3D%206500%20-%2050d)
Solving (b); The value of E when d = 30.
Substitute 30 for d in ![E = 6500 - 50d](https://tex.z-dn.net/?f=E%20%3D%206500%20-%2050d)
![E = 6500 - 50 * 30](https://tex.z-dn.net/?f=E%20%3D%206500%20-%2050%20%2A%2030)
![E = 6500 - 1500](https://tex.z-dn.net/?f=E%20%3D%206500%20-%201500)
![E = 5000](https://tex.z-dn.net/?f=E%20%3D%205000)
<em>Hence, there are 5000kwh left after 30 days</em>
The answer is -2/3x + 6 because it is the only answer with a negative fraction.
Y = 5
i think that what you meant
so the point will be (0,5) and will be a horizontal line at y=5
hope that helps
Convert 25% to a decimal which is 0.25.
Multiply 25.99 by 0.25 and get 6.4975. Round 6.49756 to 6.5.
Subtract 6.5 from 25.99 to get your answer.
The answer is $19.49
