Answer:
4 problems
Step-by-step explanation:
(I'm going to type a lot, but it isn't at all hard when you really understand and get the hang of it) If you are assigned 32 math exercises for homework and you complete 87.5% of them, this means that the problem is not asking for 87.5 % of 32, but what is left after you finish 87.5%, which means we should subtract 87.5 from 100. 100-87.5=12.5. 12.5% now represents the percent of the 32 original questions we have left to do after dinner. So, now we need to create a proportion. 12.5% means 12.5% out of 100%, with the 100% meaning 32, because that is the total amount of questions we have. so, this means we have [tex]\frac{12.5}{100}[/tex]. To use this to solve our problem, we have to act as if the 32 also represents 100%. So, we have to multiply this fraction ([tex]\frac{12.5}{100}[/tex]) by [tex]\frac{x}{32}[/tex] so that the 12.5% out of 100 lets us see how many problems 12.5% out of 100% would represents the remaining questions out of 32. so, we would solve for x (x representing the questions left to do after dinner.) So, we would form this equation and solve for x. -->[tex]\frac{12.5}{100} =\frac{x}{32}[/tex]. Now, we would cross multiply, then divide. So we would first multiply 12.5 times 32. This would give us 400. Then, we divide 400 by the 100, which gives us 4, which means that we have 4 problems left to do after dinner.
THIS IS MY LAST TIME! The boys track team needs to keep a count of how many laps they run at practice so they know the distance. Each lap is 400 meters. What is the difference between the teammate who ran the furthest and the teammate who ran the least distance?

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.

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.
help me pls!
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.

Answer:
20%
Step-by-step explanation:
so he made a total of 70 bowling attempts, and 14 out of those 70 he actually knocked all of the pins down, so what its asking, is what is 14 precent of 70 because the wording is "out of" which means its a part of the entire 70. so you now know what its asking, how do you solve it? well, you would divide 14 by 70 to get the answer in decimal form: 14 / 70 = 0.2000 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.2000 * 100 = 20.00%
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.
I'm not sure if you would want to tell your mother that you're barely getting an average. or higher than failing.
either way, hope this helps :)

Part 1
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 equation x^2 = d has how many real solutions when d > 0?
Answer:
2 real solutions
Step-by-step explanation:
d>0: two real solutions
D=0 one real solution
D<0: two complex (imaginary) solutions
Answer:
Step-by-step explanation:
This is a quadratic equation. All quadratic equations have two solutions. In this case, with d > 0, the two solutions / roots are real, one positive and one negative. To see this, take the square root of both sides of x² = d.

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).
Hence, the given inequality y < -4 is have shown in the attached graph.

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.

What is the equation of the line in slope intercept form that has a slope of 1/2 and passes through (2,3)
Answer:
y = 1/2x + 2
*view the attached graph to double check the answer*
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = mx + b
y = 1/2x + b
(2, 3) ==> substitute the numbers into the equation
y = 1/2x + b
3 = 1/2(2) + b
3 = 1 + b
-1 -1
2 = b
Our final equation: y = 1/2x + 2
Check your answer using (2, 3):
y = 1/2x + 2
3 = 1/2(2) + 2
3 = 1 + 2
3 = 3
This statement is correct
