A certain restaurant sells cups of coffee for $2 and donuts for $1.50. If the restaurant sold a total of 80 items and earned $141.50, how many donuts did the restaurant sell?
Answer: 37 donuts
Step-by-step explanation:
coffee for 2,
donuts for 1.5
c = coffee
d = donuts
lets make an equation
c*2 + (80-c)*1.5 = 141.5
from this we get:
c= 43.
if c = 43, then d is 80-43 = 37.
they sold 43 coffees, and 37 donuts.
lets check the math
43*2+37*1.5 = 141.5. math checks out

In order to help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed. Round to two decimal places.
Answer:
92.99
Step-by-step explanation:
Mean, μ = 122.6
Standard deviation, σ = 18
Recall :
Z = (x - μ) / σ
x = score
The Zscore for the lower 5% = 0.05
Using, invnorm(0.05) = - 1.645
Put Z = - 1.645
-1.645 = (x - 122.6) / 18
-1.645 * 18 = x - 122.6
-29.61 = x - 122.6
-29.61 + 122.6 = x
x = 92.99

Step-by-step explanation:
William bought 114 juice boxes for his party. At the end of the party, he had 23 juice boxes left over. How many juice boxes did people drink at William's party? *
Answer:
Number of juice boxes people drank at Williams party = 91
Step-by-step explanation:
Total juice boxes Williams bought = 114
Juice boxes left over at the party = 23
How many juice boxes did people drink at William's party?
Number of juice boxes people drank at Williams party = Total juice boxes Williams bought - Juice boxes left over at the party
= 114 - 23
= 91
Number of juice boxes people drank at Williams party = 91
(2x + 3y = 12 (5x - 2y=11
Answer:
[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]
Step-by-step explanation:
2x + 3y = 12
5x - 2y = 11
2x + 3y + 5x - 2y = 11 + 12
7x + y = 23
[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]
A polynomial function has a degree of 8. What is the maximum number of turning points?
Answer:
7
Step-by-step explanation:
To find the maximum number of turning points of any polynomial function, subtract one from the degree.
Since the degree is 8, subtract 1 from this:
8 - 1
= 7
So, the maximum number of turning points is 7.
