In a school of 600, a survey was conducted with 10% of the population. The survey was conducted to narrow the choices for the new mascot. What was the frequency of Bears, if the following was the result of the survey?
Bears=22
Panthers=15
Beavers=2
Jaguars=21 no virus file answers
Answer:
36.67%
Step-by-step explanation:
So if 600 kids in total and 10% participate, then we have 60 kids to work with. Panthers plus beavers plus jaguars = 2 + 15 + 21 = 38. 38 + 22 = the total 60 kids. 22 is 36.67% percent of 60 because that's what 22/60 equals.
Geometry problem, Fill in the blanks with the missing angle measures for the triangle shown.
Answer:
for c it is 40
for a it is 80
Step-by-step explanation:
a straight line is 180 and
180-140=40
a triangle is 180, so 40+60 is 100
180-100=80

Kim's school is selling tickets to a play. On the first day of ticket sales the school sold 5 senior citizen tickets and 6 child tickets for a total of $148. The school took in $189 on the second day by selling 7 senior citizen tickets and 7 child tickets. Find the price of a senior citizen ticket andthe price of a child ticket.
Answer:
Child $13 and Adult $14
Step-by-Step
x=cost of child tix
y=cost of adult tix
first day: 5y+6x=148
2nd day: 7y+7x=189
series of equations so solve for one variable
7y=189-7x
y=27-x
then plug into other equation
5(27-x)+6x=148
135-5x+6x=148
x=148-135
x=13
then plug into y equation
y=27-13
y=14

runs (x) and the number of minutes she dances (y) every day.
Part B: How much time does Jackie spend running every day? Show your work.
Part C: What is the greatest amount of time she could spend dancing every day, given she will take a
run. Explain your reasoning.
Answer:
Step-by-step explanation:
Part A: Write a pair of linear equations to show the relationship between the number of minutes Jackie
runs (x) and the number of minutes she dances (y) every day.
x=x/2 y= 2x
Part B: How much time does Jackie spend running every day? Show your work.
75 - 25 = 50 /2 =25
total dance number of activities

For an experiment, the temperature of a liquid must stay above 60.7°F. The starting temperature of the liquid is 90.1°F. It is placed in a cooler, which lowers its temperature 4°F each minute. How many minutes can the liquid can stay in the cooler?
Select from the drop-down menus to correctly complete the statement. The liquid can stay in the cooler |___| minutes.
A. At most 7.35
B. At least 7.35
C. fewer than 7.35
D. more than 7.35
Answer:
The answer is C I took the k12 quiz and it said this is correct. Please mark brainliest. Thank you!!!
Step-by-step explanation:
The liquid can stay in the cooler |x≤7.35| minutes. Therefore, option A is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, for an experiment, the temperature of a liquid must stay above 60.7°F.
The starting temperature of the liquid is 90.1°F.
Here, 90.1-60.7
= 29.4
It is placed in a cooler, which lowers its temperature 4°F each minute.
Now, number of minutes =29.4/4
= 7.35 minutes
Therefore, option A is the correct answer.

B) x2 + y2 = 2
C) 2 x2 + 2 y2 = 4

hey i need help solving a Krypto
numbers: 13, 16, 23, 1, 3 equals: 20
thanks in advanced :)
Theres four solutions which you wont find with most Krypto solvers since it uses .333 repeating.
The solutions are:
16 / 3 = 5.3333333333333
5.3333333333333 - 1 = 4.3333333333333
13 / 4.3333333333333 = 3
23 - 3 = 20
13 / 3 = 4.3333333333333
4.3333333333333 + 1 = 5.3333333333333
16 / 5.3333333333333 = 3
23 - 3 = 20
23 / 3 = 7.6666666666667
7.6666666666667 - 1 = 6.6666666666667
16 - 13 = 3
6.6666666666667 x 3 = 20
16 - 13 = 3
23 / 3 = 7.6666666666667
7.6666666666667 - 1 = 6.6666666666667
6.6666666666667 x 3 = 20
