Michelle is planting flowers in her garden. She wants the ratio of daisies to carnations to be 3 to 2. Michelle wants to plant a total of 30 flowers. How many daisies should she plant?
The ratio of daisies to carnations is 3 to 2, which means for every 3 daisies there are 2 carnations.
Let x be the number of daisies Michelle plants
The number of carnations she plants is (2/3)x
The total number of flowers is x+(2/3)x=30 flowers
(5/3)x=30 flowers
x=18 flowers
Michelle should plant 18 daisies. Answer: \boxed{18}.
Ross drives 396 miles in 6 hours. If Ross continues to drive at the same rate, how many miles can he drive in 12 hours?
Since Ross drives 396 miles in 6 hours, his rate of driving is 396 miles/6 hours = <<396/6=66>>66 miles/hour.
Therefore, Ross can drive 66 miles/hour * 12 hours = <<66*12=792>>792 miles in 12 hours. Answer: \boxed{792}.
To find out how many daisies Michelle should plant, we first need to determine the total number of flowers that correspond to the ratio of 3 to 2.
Let's say the ratio is 3x to 2x, where x represents a constant. The total number of flowers in the ratio is calculated by adding the two parts together: 3x + 2x = 5x.
Since the total number of flowers that Michelle wants to plant is 30, we can set up the equation 5x = 30 to solve for x.
Dividing both sides of the equation by 5 gives us x = 6.
Now that we know the value of x, we can find the number of daisies by multiplying 3x by 3: 3 * 6 = 18.
Therefore, Michelle should plant 18 daisies in her garden.
