stephanie's car would require 3 gallons of gasoline to get to the zoo
Answer:
a)5:2
b)14
c)17
Step-by-step explanation:
The ratio for babies to nursery workers is 5:2
To find the answer to b, we find how much you have to multiply 2 by to get 35, which is 7 and multiply that by the number of workers, 2, so you need 14 workers
To find the answer to c multiply 2 bye 3.5 to get 7 and multiply 5 by 3.5 to get 17.5 now rounf down so the answer to c is 17
Let's start by putting the information on the table into fraction form.
So:
O: 9/20
Y: 5/20
B: 6/20
We now know the probability of picking the different colour chips when the experiment is repeated 20 times but we want to know the probability if the experiment was repeated 80 times. So, we have to find out what number to multiply the probabilities by to get the answer over 80. So:
80/20 = 4
4x9 = 36
Thus the probability of picking an orange chip should be 36/80 and so she should expect to pick up 36 orange chips !
Answer:
14 installatons
42 service calls
Step-by-step explanation:
Let x = no. of new installations
y = no. of service calls
(1) x + y = 56 (2) 450x + 75y = 9450
y = 56 - x 450x + 75(56 - x) = 9450
450x + 4200 - 75x = 9450
375x = 5250
x = 14 installatons
y = 56 - 14 = 42 service calls
