It takes leon 13 hours to seal his driveway working by hinself. If michael helps leon, they can seal the driveway in 7 hours. Ho

Monica [59]

Answer:

15.1667 hours (15 hours and 10 minutes)

Step-by-step explanation:

Using the concept of "distance = speed * time", we can formulate equations to solve this problem.

Let's call Leon's speed X, Michael's speed Y and the length of the driveway D.

If leon takes 13 hours alone, we can write the equation:

D = X * 13

If Michael helps Leon, we have this equation:

D = (X+Y) * 7

(The total speed is the sum of their speed, as they are working together)

Making the first equation equate the second, we have:

13*X = 7*X + 7*Y

7*Y = 6*X

X = (7/6)*Y

If we use this value of X in the first equation, we have:

D = 13*X = 13*(7/6)*Y = 15.1667*Y

So we have that Michael would take 15.1667 hours (15 hours and 10 minutes) to seal the driveway alone.

Solve this problem. A florist sells holiday bouquets that use roses and carnations in a ratio of 2 to 7. She receives a shipment

DIA [1.3K]

Let roses be R and carnations be C

"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically

$R:C\\2:7\\7R=2C\\$

since C = 343 we plug 343 in $7R=2C$ :

$7R=2(343)\\7R=686\\R=\frac{686}{7} \\R=98$

ergo, she needs 98 roses

to make sure of the answer:

"ratio of 2 to 7" is technically a fraction => $\frac{2}{7}$

and since the ratio of the roses to the carnations is the same as $\frac{2}{7}$ we plug the values R = 98 and C=343:

$\frac{R}{C}=\frac{98}{343}=\frac{2}{7}$

check with calculator too, hope i helped <33
