Answer:
D
Step-by-step explanation:
To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.
A. x would be weeks and it would decrease by 7x. This is not it.
B. 15 songs packages would have x be the number of packages not the price. This is not it.
C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.
D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.

P(z < 3)
From the normal distribution table,
P(z < 3) = 0.9987
Answer:
The maximum number of pounds p is 224
Step-by-step explanation:
Let
p ----> the maximum number of pounds he can pull without going over the weight limit
we know that
121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds
In this problem the word "at most" means "less than or equal to"
so
The inequality that represent this situation is
solve for p
subtract 121 both sides
therefore
The maximum number of pounds is 224
Answer:
Step-by-step explanation:
Rate X Time = distance
Therefore:
r (rate) X 5 (hours) = 600 (distance)
r = 600/5
r = 120 miles per hour
The rate of speed of the jet is 120 mph.
Then, to find out the distance flown in 13 hours:
120 (rate) X 13 (time) = d (distance)
120 X 13 = d
1560 = d
The distance flown in 13 hours is 1560 miles.
