168 hours or 4.66667 im not sure
Answer:
91 campers can swim
Step-by-step explanation:
step 1
Find the number of campers
we know that
The ratio of counselors to campers at a camp is 1 : 9
so
by proportion
Find the number of campers if there are 13 counselors
Let
x-----> the number of campers
1/9=13/x
x=9*13=117 campers
step 2
How many campers can swim?
we know that
The ratio of campers who can swim to campers who cannot swim is 7 : 2
so
The ratio of total campers to campers who can swim is 9 : 7
by proportion
Find how many campers can swim for a total of 117 campers
Let
x----> the number of campers that can swim
9/7=117/x
x=117*7/9
x=91 campers can swim
Answer:
1/4h
Step-by-step explanation:
If the time for the car trip is x, then given that a car trip is 1/2h shorter than a bus trip, it means that adding 1/2h to the time for a car trip gives the time for the bus trip.
Hence, the time for the bus trip
= (1/2 + x)h
since the bus trip is 3/4h, it means that
1/2 + x = 3/4
collecting like terms,
x = 3/4 - 1/2
= 3/4 - 2/4
= 1/4
Hence the car trip is 1/4h.
Answer:
ok sorry i could not put this into a formula im have to go but i will show you a really easy way.
Step-by-step explanation:
for number 1 i got (7,-1)
This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.
The correct way for doing number 1 is using the distance formula i believe but im running out of time
for the second one i got (3, -1/2)
we do this by using the midpoint formula.
The first picture is for number one and the second for number 2
