It will take them 3/4 of an hour together.
Camille can mop and vacuum 1/2 of the house per hour.
Lawrence can mop and vacuum 1/2 of the house per hour.
Gaston can mop and vacuum 1/3 of the house per hour.
Working at this rate for x amount of time, they can all three complete 100% of the job:
1/2x+1/2x+1/3x=1
Combining like terms,
1 1/3x = 1
3/3x + 1/3x = 1
4/3x = 1
Divide both sides by 4/3:
4/3x÷4/3 = 1÷4/3
x = 1/1÷4/3
x = 1/1×3/4
x = 3/4

<u>Answer: </u>
The equation of the circle with center (0, 1) and a radius of 10 is
<u>Solution:
</u>
Equation of circle whose center (h, k) and radius r is given as,
---- eqn 1
From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.
Hence we get, h = 0 ; k = 1; r = 10
By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as
On Simplifying we get
Expand using the formula
Hence equation of the circle with center (0, 1) and a radius of 10 is
Answer: Each donor donated $70.5 per lap.
Step-by-step explanation:
1. If she got 8 donors and each one of them sponsored 5 laps, then the total number of laps was:
laps
2. Hailey raised a total of $2,820, therefore, you can calculate the amount of money donated by each donor (which you can call ) by dividing $2,820 by 40 laps, as you can see below:
