Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p= -0.5x²+25x-111 models the profit of the fundraiser. What's the smallest amount, in dollars, that you can charge and make a profit of at least $114?
Answer:
12
Step-by-step explanation:
if we know we want a profit of at least 114, we need to solve for x.
if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.
-0.5(12)^2 + 25(12)-111 = 117

The social studies teacher wants to know whether the students in the entire school prefer a model United Nations activity or a student government activity. The teacher draws a random sample from the following groups:
All teachers in the school
All boys in each grade
All students in each grade
All students in the social studies club
Which group best represents the population he should take a random sample from to get the best results for his survey?
Answer:
all students in the club
Step-by-step explanation:
Answer:
C. All students in each grade
Step-by-step explanation:
Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.

find x and hurry im under a time limit
Answer:
x = 13
Step-by-step explanation:
Using the 48° angle, we find out that the angle opposite of angle y° is also 48° according to the corresponding angles theorem. Then, you would subtract 48 from 180 to get the degrees of angle y, which would be 132°. Next, you need to subtract 132 from 180 to get the angle measure of the (5x - 17)° angle. (180 - 132 = 48) Once you have done that, all you have to do now is figure out what value of x makes it equal to the degree measure you found by subtracting 132 from 180. I tried it with x = 13, which came out as a correct answer. So x must be 13.
(5x - 17)°
(5(13) - 17)°
(65 - 17)°
(48)°
48°
The angle equals 48° and x equals 13.

Andrew scores 79, 86, 63, and 82 on his recent tests, when measure of centeral tendency should he use to describe to his mom his his tests are going
Answer:
e
Step-by-step explanation:
Central tendency means “the statistical measure that identifies a single value as representative of an entire distribution." These measures include mean, median, and mode.
Andrew scores 79, 86, 63, and 82 on his tests.
63, 79, 82, 86
Mean: 79 + 86 + 63 + 82 = 77.5 or
Median: 79 + 82 = 80.5
(you have to add these numbers bc there is no exact median as none are repeating)
Mode: There is no exact mode since there is no repeating numbers.
He should use the mean bc the mean is a pretty good number.

Which statement is true about the graphs shown?
I need help on this ASAP!
Answer:
4/9
Step-by-step explanation:
need more words to send
Answer:
Step-by-step explanation:
There are at least 2 ways you could do this. The best way is to use algebra. The trick is to equate 0.444444 to x, and then create a second equation by multiplying the first equation by 10. In doing this, you can subtract the two equations and that will get rid of the decimal.
10x = 4.444444...
x = .444444... Now subtract these 2 equation
9x = 4 Divide both sides by 9
9x/9 = 4/9
x = 4/9.
Since you are given choices, you could put each one into your calculator.
1/9 = 0,111111 not the answer.
40 /99 = 0.40404040 which is close but not the answer.
4 / 99 = 0.040404 ... which again is close but not the answer.
Clarissa is making punch for a party. She mixes 64 fluid ounces of orange juice, 64 fluid ounces of pineapple juice, and 36 fluid ounces of apple juice.
Let p represent the total amount of punch that Clarissa mixes.
Which equations could be used to find the value of p?
Select each correct answer.
A.64 + 64 + 36 = p
B.64 × 2 + 36 = p
C.64 × 64 × 36 = p
D.64×2−36=p
E.64+64−36=p
Answer: A and B.
Step-by-step explanation: The first option works because Clarissa is adding 64 fluid ounces of both orange and pineapple juice and 36 fluid ounces of apple juice which makes it an addition problem. Option B works as well because it is similar to option A, only it shortens the problem by multiplying 64 twice, because 64 pops up twice. Options C, D, and E don't work because it doesn't include taking away any juice or multiplying it in immense amounts, so that's why those are wrong.
Hope this helps! :)
Can someone find F(12).

Please and thank you?
Answer: 909.03
Step-by-step explanation:
We know that the equation is an exponential function, it can be written as y=ab^x
[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]
[tex]\Rightarrow ab^1=11[/tex]
[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]
[tex]\Rightarrow a=\frac{11}{b}[/tex]
a = 11/b, substitute it in equation 1
[tex]100 &=a b^{6.5}[/tex]
[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]
[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]
[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]
[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]
[tex]\Rightarrow {b} = 1.49379[/tex]
a = 11/b
a = 11/(1.49379)
a = 7.36382
Equation: y = (7.36382)(1.49379)^x
Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]
[tex]\Rightarrow 909.03[/tex]
Therefore, f(12) = 909.03 for the exponential function

2. A cube of ice has a surface area of 24 square inches. What is the volume of the ice?
3. solve 1/3x^3 = 9
Answer:
1. = 7.5
2. = 8 inches
3. = x=3
Step-by-step explanation:
1) 7.5 miles north-east
2) 8 cubic inches
3) x = 6.24
Step-by-step explanation:
1) Use pythagorus thereom:
a² + b² = c²
4.5² + 6² = c²
20.25 + 36 = c²
c = √56.25
c = 7.5
7.5 miles north-east
2) The ice is a cube,
Surface area = 24
Cube has 6 sides
24 / 6 = 4
1 side = 4
1 length = √4
1 length = 2
Volume = bhd
Volume = 2³
Volume = 8 in.³
3) ⅓x³ = 9
⅓x = (3√)9
⅓x = 2.08
x = 2.08 / ⅓
x = 6.24

The given inequality y < -4 is shown in the attached graph. The correct answer would be an option (B).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Inequalities with "< or > "symbols are shown with a dashed line to indicate that the line is not inside the area. Inequalities involving symbols are depicted with a solid line to indicate that the line is included in the region.
We have been the given inequality y < -4
Rearrange the equation such that "y" is on the left and all other variables are on the right.
Plot the "y=" line (a solid line for y or y, and a dashed line for y or y>). The shade above the line for a "greater than" (y> or y), or below the line for a "less than" (y or y).

Solving the Question
We're given:
There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.Set variables:Let a represent the number of children who swam.
Let b represent the number of adults who swam.
Create equationsBecause we've set two variables, we need two equations to be able to find the answers.
One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.
Number of people:
[tex]a+b=478[/tex]
The number of children + the number of adults = 478 in totalPrice:
[tex]1.75a+2.25b=975[/tex]
$1.75 per child + $2.25 per child = $975 in totalSolve equations[tex]a+b=478[/tex][tex]1.75a+2.25b=975[/tex]We can solve this question using substitution, where we plug one equation into the other.
Isolate a in the first equation:
[tex]a+b=478\\a=478-b[/tex]
Plug the first equation into the second equation by replacing a:
[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]
Solve for b:
[tex]1.75(478-b)+2.25b=975[/tex]
⇒ Open up the parentheses:
[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]
⇒ Subtract 836.5 from both sides to isolate b:
[tex]-0.5b=138.5[/tex]
⇒ Divide both sides by -0.5:
[tex]b=277[/tex]
Therefore, there were 277 adults in total.Solve for a:
[tex]a+b=478[/tex]
⇒ Replace b with 277:
[tex]a+277=478\\a=201[/tex]
Therefore, there were 201 children in total.Answer
There were 201 children and 277 children at the pool that day.
