Answer:
15
Step-by-step explanation:
3/10=n/50
cross multiply
3×50=10n
dividing both sides by the coefficient of n
150/10=10n/10
15=n
n=15

Determine whether the claim is valid. Explain.
Ximena conducts a survey on how students spend their money.
Sample: 80 students randomly chosen as they leave the school.
Question: Do you spend the majority of your money keeping up with today's hottest music or on other things?
Claim: Students spend the majority of their money buying music.
Answer:
The claim that students spend the majority of their money buying music is not valid. The survey Ximena conducted is not representative of the entire population of students, as it only surveyed 80 students randomly chosen as they left the school. Therefore, the results of the survey cannot be used to make a general statement about how all students spend their money.

Step-by-step explanation:
ANSWER ASAP PLEASE What is the solution for the system of linear equations shown in the graph? a coordinate grid with one line that passes through the points 0 comma 1 and 1 comma 2 and another line that passes through the points 0 comma 0 and 1 comma negative 3
Step-by-step explanation:
The solution of for the system of linear equations shown in the graph is x = -1/2 and y = 3/2.
Given points of two lines:-
Line 1 : (0,0) , (1,-3)
Line 2 : (0,2) , (-1,1)
Let the Equation of Line 1 : y = mx + c
m = (-3-0)/(1-0) = -3/1 = -3
Putting (0,0) in y = mx + c, we get
0 = -3*0 + c
0 = 0 + c
c = 0
Hence,
Equation of Line 1 : y = -3x or y + 3x = 0 ...(1)
Similarly, we can find,
Equation of Line 2 : y = x + 2 or y - x = 2 ...(2)
(1) - (2),
4x = -2
x = -2/4 = -1/2
Putting the value of x in (2), we get,
y - (-1/2) = 2
y + 1/2 = 2
y = 2-(1/2)
y = 3/2

Regan and her friends shared a Big Dipper sundae at Skylight Ice Cream Shop. The 3 of them split the bill, and each person paid $3.75.
Let b represent the total cost of a Big Dipper sundae. Which equation models the problem?
Answer: B=$3.75×3
Explanation: we want the full price of the Big Dipper so the equation will equal to B, there were 3 friends that split the bill $3.75 each so if we multiple 3.75 by 3 we will get the total cost of the Big Dipper which is $11.25
The solution is: b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.
Here, we have,

Write an equation to represent "j divided by 9 is 5." (use / for division)
Write an equation to represent "33 is 15 less than k."
Answer: k - 15 = 33
Step-by-step explanation:
So basically you just translate the problem into math form. 33 is a #, is is an = sign so, 33 = so far. Then 15 is less than k, which is not 15 - k but k - 15. There's a difference. Say k is 30, so 30 - 15 and not 15 - 30. So then you have 33 = k - 15, then I just switched it around to look better and done.
Answer:
k-15=33

Adrien has 4 liters of milk. He drinks y liters each day.
a) If Adrien has x liters of milk left after one week, express x in terms of y.
b) State the independent and dependent variables in the question
Answer:
A) X = 4 - 7Y
B) Independent Variable: Y, Dependent Variable: X
Step-by-step explanation:
Explanation for A:
We form a simple equation, knowing that if he drinks y liters each day after one week it would be 7Y. Then, we'd subtract it from 4
So equation would be X = 4 - 7Y
Explanation for B:
The independent is Y because doesn't change or get affected by another variable, and the dependent variable is X because depending on the value of Y, X will change accordingly.

14. Two hundred tickets were sold for a concert. Forty percent of the tickets were pre-sold. The remaining tickets were sold at the door. Sasha finds the number of tickets sold at the door in the following way:
First, she subtracts 40% from 100% to get 60%.
Then she finds the number that is 60% of 200.
Is Sasha correct? Use words and numbers to explain your answer.
Answer:80

what you do is since there’s a whole and a present multiply them and then divide by 100 and there’s your answer.So Sasha was wrong.(btw I’m in 6th grade and this is exactly what we are working on so I know lol)
surface area of cuboid
Answer:
Volume equals 60
Step-by-step explanation:
volume = (width)(height)(length)
volume= (2.5)(4)(6)
volume= 60
The amount of glass used is equivalent to the surface area of the glass surfaces.
As the problem is specifying the top of the aquarium is open, we'll assume that it is not included for the surface area calculations.
[tex]A=2 (2.5 \times 4) +2(6\times4)+(6\times2.5)[/tex]
The first term represents the area of two 2.4 x 4 faces of the aquarium. The second term is the area for the two 6 x 4 faces. The last term is for the 6 x 2.5 base of the aquarium, and it is not multiplied by 2 as we are not including the top of the aquarium.
[tex]=2 \times 10 + 2\times24 + 15[/tex]
[tex]=83 \text{ ft}^2[/tex]
The aquarium has a surface area of 83 square feet. Hence, 83 square feet of glass was used to build the tank.

Can anyone make an explaination?
Answer:
It is point c
Step-by-step explanation:
ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *
Answer:
C
Step-by-step explanation:
In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.
Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.

A construction crew has just finished building a road. The crew worked for days. If they built kilometers of road each day, find the total length of road they built.
____ kilometers
Answer:
3.602 km.
Hope this helps!
Answer: If t would be the number of days, d the distance they built and x the total they built, then the relationship would be x = td.
Step-by-step explanation: If they build a certain amount of road every day, then in two days, they're gonna build twice that much road, in three days triple, etcetera. Therefore you just need to multiply the amount of days they work with the amount of road they build in a day.

Question 2(Multiple Choice Worth 2 points)
(Experimental Probability MC)
In a repeated experiment, Kim rolled a fair die twice. The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36. Predict how many times the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.
3
9
10
18
9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.
As, Expected number of outcomes = theoretical probability * number of trials
Expected number of outcomes = 3/36 x 108
= 9
Thus, the required value is 9.
