a store sells coffee beans for $8 per bag. if a bag contains 5 lbs., find the cost of coffee beans per pound.
The cost of the coffee beans per pounds is 1.6 pounds.
Given that,
Coffee beans are available in stores for $8 per bag.
We have to find the price of coffee beans per pound if a bag weighs 5 pounds.
one lb is one pound.
To convert it from pounds to kilogram's, increase it by 1. (or just change the unit). This shows that the number of pounds is exactly the same.
Let us take the cost as x.
We get,
5x=8
x=8/5
x=1.6
Therefore, The cost of the coffee beans per pounds is 1.6 pounds.

A survey by the national retail federation found that women spend on average r146.on a saturday lunch. assume the standard deviation is r29.44. find the percentage of women who spend less than r190.00 on a saturday lunch. assume the variable is normally distributed
The percentage of women who spend less than $190.00. Assume the variable is normally distributed is 0.0694 or 6.94%
Given that,
Women spend an average of $146 on a Saturday lunch, according to a national retail federation poll. Suppose $29.44 is the standard deviation.
To find : How many ladies or the percentage of ladies spend less than $190 on a Saturday lunch
P(X < 190) = P(x-μ/σ < 190 -146.21 /29.44)
= P(Z > 1.487)
= 0.0694
So, the proportion of female consumers who spend less than $190 and that the variable has a 0.0694 or 6.94% normal distribution.

Bill's bank charges $27.50 for overdraft fee and $3.50 for using an ATM out of network. Bill has $25 in his checking account at First Bank. Later that day he had a check clear his account for $50 and then added an ATM debit of $80. How much does Bill owe the bank. Explain your answer
Total sum that Bill owe the bank is $36
Given,
The overdraft fee charged by the bank = $27.50
The charge for using an ATM out of network = $3.50
The amount in the checking account = $25
The amount for check clearing = $50
ATM debit amount added = $80
We have to find the money Bill owe the bank;
Overdraft;-
A bank will grant a customer an overdraft when their account balance is 0 so they may pay their payments and other expenses.

Answer:
negative
Step-by-step explanation:
because the line falls from left to right, the line has a negative slope. =)
Answer: Negative
Step-by-step explanation:
This line is "going down the stairs," or starting from the upper lefthand side to the bottom righthand side. This means we have a negative slope.
If you need to find the slope;
We will use the "rise over run" method. Starting at (-2, 3) we will count 4 units down and three units right to (1, 1) for a slope of -4/3.

Answer:
∴ x = 1, y = -3
Step-by-step explanation:
x - y = 4 ------ equation (1)
2x + y = 5 ------ equation (2)
Add equations (1) and (2):
(2x + y) + (x - y) = 5 - 4
2x + y - x - y = 1

how long does a ford raptor traveling at 75 mph take to travel 259 mi, in hours
A. 0.4
B. 10/3
C. 0.3
D. 175
Answer:
3.45 hours. The closest answer option to this value would be (10/3), which is technically 3.3333 hours, but it is the closest correct option, by far. 3.333 hours would suggest the distance was 250 miles, not 259 (250/75) = 3.33333)
Step-by-step explanation:
Distance, D, is found by multiplying the speed (75 mph) times the time, x (in hours. If distance is 259 miles, we can write:
259 miles = (75 miles/hr)*x
Rearrange to find x [divide both sides by (75 miles/hr):
x = (259 miles/(75 miles/hr)
Note the units: miles cancel and hours moves to the top, leaving only hours, which is what we want.
(259 hours)/75 = 3.45 hours
