Answer:
Hence, 70 people out of 100 who had attained the previous year
Step-by-step explanation:
If this is completely proportional, you'd make the formula
[tex] \frac{420}{600} = \frac{x}{100} [/tex]
Cross multiply
[tex]42000 = 600x[/tex]
Then we just divide by 600
[tex]x = 70[/tex]
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 equation.
The requried solutions are as follows,
(a) Equation x in terms of y is given as x = 4 - 7y.
(b) In the equation x is the dependent variable and y is the independent variable.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here
Adrien has 4 liters of milk. He drinks y liters each day.
Adrien has x liters of milk left after one week
So
x = 4 - 7y
In the above equation model, it is clear that x changes as y changes, although x is the dependent variable and y is the independent variable.

Determine if the table shows a proportional relationship.
x 36.5 23.2 63.3
y 18.25 11.6 21.1
Group of answer choices
a. Yes, it is proportional because the ratios for y over x are all equivalent to one-half.
b. Yes, it is proportional because the ratios for y over x are all equivalent to one-third.
c. No, it is not proportional because 18.25 over 36.5 is not equal to 23.2 over 11.6.
d. No, it is not proportional because 18.25 over 36.5 is not equal to 21.1 over 63.3
Answer:
Because 18.25/36.5 and 21.1/63.3, the numbers in the table do not represent a proportionate connection. First set of data: y/x = 18.25/36.5 = 0.5
Values for the second pair are: y/x = 11.6/23.2 = 0.5
Values for the third pair are: y/x = 21.1/63.3 = 0.3
Because the value of y/x varies among the table's values, the table does not depict a proportionate connection. A value table must have an identical ratio of y/x between each pair of values for a proportional relationship to be seen. K, or the proportionality constant, is the constant.
Because 18.25 over 36.5 is not equivalent to 21.1 over 63.3, we may conclude that: D. No, does not demonstrate a proportionate connection.
Step-by-step explanation:
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

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.

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.

You bought some jeans for $55. Today they were on sale for $49.50. What was the percent decrease in price?
10% decrease
Explain how you these answers are right
Answer:
Step-by-step explanation:
Profit % = [tex]\frac{New Value - Old Value}{Old value}[/tex]x 100
Loss % = [tex]\frac{Old Value-NewValue}{Old Value}[/tex]
Profit % = [tex]\frac{16.1-5}{5}[/tex] × 100
= [tex]\frac{11.1}{5}[/tex] x 100
= 11.1 x 20
= 222% increase
∴ Hence, proved that the answer is correct.
Profit % = [tex]\frac{57.6-40}{40}[/tex]×100
= 44% increase
∴ Hence, proved that the answer is correct.
Profit % = [tex]\frac{63.6-60}{60}[/tex]x 100
= 6% increase
∴ Hence, proved that the answer is correct.
Loss % = [tex]\frac{110-13.2}{110}[/tex]x 100
= 88% decrease
∴ Hence, proved that the answer is correct.
Loss % = [tex]\frac{55-49.5}{55}[/tex]x 100
= 10% decrease
∴ Hence, proved that the answer is correct.

Answer:
Step-by-step explanation:
Old Value: 5
New Value: 16.1
16.1-5=11.1
11.1 divided by 5= 2.22
2.22/1 x 100=222%
222% increase
Old Value: 40
New Value: 57.6
57.6-40=17.6
17.6 divided by 40= 0.44
0.44/1 x 100= 44%
44% increase
Old Value: 60
New Value: 63.6
63.6-60=3.6
3.6 divided by 60= 0.06
0.06/1 x 100= 6%
6% increase
Old Value: 110
New Value: 13.2
13.2-110= -96.8
-96.8 divided by 110= -0.88
-0.88/1 x 100= 88%

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.

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.

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.

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.
