What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Calculating time of Betsy total work for getting paid :
Betsy Working from 6:00 AM to 12:00 PM = 6 hour
Betsy takes an unpaid lunch break from 12:00 PM to 1:00pm = 1 hour
Betsy Working from 1:00 PM to 3:30 PM = 2.5 hour
Now adding-up all the time = 6 + 1 + 2.5 hour = 9.5 hours or 9 hours 30 minutes.
Therefore, Betsy works for about 9 hours 30 minutes daily.

The drama club at NAMS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200. They need to keep track of how many of each type drink was sold so that they can make predictions for future sales. Monica knows that they used 275 cups that night. If the hot chocolate sells for 75 cents and coffee sells for 50 cents, how much of each type of drink were sold?
Answers
Answer:
Coffee = 25
Hot Chocolate = 250
Step-by-step explanation:
Coffee: c
Hot Chocolate: h
0.75h + 0.50c = 200
h + c = 275
h + c = 275
h = 275 - c
0.75h + 0.50c = 200
0.75(275 - c) + 0.5c = 200
206.25 - 0.75c + 0.5c = 200
-0.25c = -6.25
-0.25c/-0.25 = -6.25/-0.25
c = 25
0.75h + 0.5(25) = 200
0.75h + 12.5 = 200
0.75h = 200 - 12.5
0.75h = 187.5
0.75h/0.75 = 187.5
h = 250
Check: c = 25; h = 250
0.75h + 0.50c = 200
h + c = 275
0.75(250) + 0.5(25) = 200
187.5 + 12.5 = 200
200 = 200
h + c = 275
250 + 25 = 275
275 = 275
The drama club sold 250 hot chocolates and 25 coffee drinks.
EquationEquation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of hot chocolate and y represent the number of coffee. From the question the equation are:
x + y = 275 (1)0.75x + 0.5y = 200 (2)From both equations:
x = 250, y = 25
The drama club sold 250 hot chocolates and 25 coffee drinks.

i will mark you as brianilest The school band sold T-shirts to raise money for an upcoming trip. The band sold 400 T-shirts on Saturday and on Sunday, it will sell 30 percent of that amount. Which statements are true about the number of T-shirts that the band will sell on Sunday? check that all apply A. the answer will be less than 400 because 30 is less than 100 B. The answer will be greater than 400 because 300 percent is greater than 100 C. (100)(4)=400 so 30 (4) is the number of T-shirts the band will sell on Sunday. D. The band will sell 430 T-shirts on Sunday or E. The band will sell 120 T-shirts on Sunday.
Answers
Answer:
A and E
Step-by-step explanation:
A is correct because if you have less than 100 percent of something then the value will be less than the original value.
E is correct because 30 percent of 400 is 120 so the band will sell 120 t-shirts on Sunday.

Answers
Answer: a = 45°
Step-by-step explanation:
The measure of∠PSR is given: 90°
Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.
The total of all angles in a triangle is 180. So subtract 90, then divide by 2.
180-90 = 90
90/2 = 45
a = 45°
If "b" is supposed to be the measure of ∠SRQ, that is 15° The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr. Rachal used 236. How many more experiments do they do with the tool? How many tools are left?
Answers
Answer:
Step-by-step explanation:
Total number of tools for both = 564.
Dr Brown used 386 tools for 6 experiments.
average number of tools per experiment used by Dr Brown = [tex]\frac{386}{6}[/tex]
= 64[tex]\frac{1}{3}[/tex]
Dr Rachal used 236 tools for 8 experiments.
average number of tools per experiment used by Dr Rachal = [tex]\frac{236}{8}[/tex]
= 29[tex]\frac{1}{2}[/tex]
i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64[tex]\frac{1}{3}[/tex])
= 2.7668
Dr Brown can do two more experiments.
The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29[tex]\frac{1}{2}[/tex])
= 11.1186
Dr Rachal can do 11 more experiments.
ii. Number of tools left after Dr Brown's experiments = 564 - 386
= 178
Number of tools left after Dr Rachal's experiments = 564 - 236
= 328

Median: middle value if there are an odd number of data values, or the average of the two middle values if there are an even number of data values
Mode: data item seen most often
Outlier = data value that is extreme

Mrs. Rodriquez has 24 students in her class. Ten of the students are boys. Jeff claims that the ratio of boys to girls in this class must be 5:12. What is Jeff’s error and how can he correct it?
Answers
Answer:
See Below
Step-by-step explanation:
Total no of students = 24
No of boys = 10
So, no of girls = 24 - 10 = 14
Ratio of boys to girls = 10/14 = 5/7 = 5 : 7
So the ratio of boys to girls should be 5 : 7 and not 5 : 12

(Sin27) / 11 = (sin x) / 15
cross multiply
15 sin27 = 11 sin x
keep in calculator as you divide 15sin27 by 11.
sin x = .6190779542
do sin ^ -1 (.6190779542) (It’s a key on the calculator.)
x = 38.25*
9514 1404 393
Answer:
38.2°
Step-by-step explanation:
According to the equation you are give, ...
sin(x)/15 = sin(27°)/11
Multiplying by 15 gives you ...
sin(x) = 15·sin(27°)/11 ≈ 0.619078
The inverse sine function is used to find the angle x. It may show as sin⁻¹ on your calculator.
x = arcsin(0.619078)
x ≈ 38.2°
_____
Additional comment
x is shown in the figure as an acute angle, so that is the value we have chosen. The other angle that has sin(x) = 0.619078 is the supplement of this, or 141.8°. The two solutions are shown in the 2nd and 3rd attachments.
