<h2>k = 7</h2>
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Let's start with the easiest bits.
We know the probability of drawing a red card is 1/4, this means every four cards there is one red. So, 12/4 = 3, there are 3 red cards in the 12 card pile.
Next, we are also given the probability of drawing a blue card us 1/12. In the same fashion, we can figure out there is 1 blue card.
Finally, we are told the probability of drawing a green card is the same as drawing a yellow card. Therefore there is the same amount of green cards as yellow.
There are 8 cards left that are green or yellow, as 12 - 1 - 3 is 8. 8/2 is 4, so there are 4 green cards in the box.
Hope this helps!
Answer:
she will make 32 burger patties.
One way:
8 x 4 = 32
the fraction will get reversed so it turns to 4.
Second way(basically the same as the first way):
8 divided by 1/4 = 8 x 4= 32
You just have to divide 8 by 1/4. The fraction gets reversed in divisions so it turns to 4.
Answer:
Step-by-step explanation:
Let y represent the distance travelled downwind by the bird from its nest.
Distance = speed × time
A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. Distance covered in travelling downwind is
2 × 18 = 36 miles
On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after 3 hours. It means that the speed at which the bird travelled is 18 - 3 = 15 mph. Also, the distance covered in 3 hours is 36 - 5 = 31 miles. Therefore,
a) distance of the entire trip is
36 + 36 = 72 miles
b) time spent in travelling downwind from its nest is 2 hours
Time for the return part is
3 hours + 5/15 = 3 + 1/3 × 60 minutes
= 3 hours 20 minutes
Total time for the trip is
2 hours + 3 hours 20 minutes
= 5 hours 20 minutes 0 seconds
Answer:
Option A, 9b + 10s is correct
Step-by-step explanation:
The complete question is
At cycle and sport customers can rent bikes, electric scooters, kayaks, canoes, or paddleboards by the hour. Ari is renting a bi ke, and meg is renting an electric scooter. Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours (Please answer ASAP) A. 9b + 10s B. 9 + 10 C. (9+b) + (10 + s) D. 9 + 10 x b + s
Solution
The price of renting a bike for one hour is $9
The price of renting a scooter for one hour is $10
Given -
Ari rents a bike for b hours and Meg rents a scooter for s hours
Total cost of renting a bike is 9 * b
Total cost of renting a scooter is 10* s
The total cost of renting both the bike and scooter is
9b + 10s
Hence, option A is correct
