Answer:
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Subtract: (-2x^4-4y^3+4z^3+6)-(-9x^4-3y^3+4z^3+9)
Answer:
Step-by-step explanation:
(-2x⁴ - 4y³ + 4z³ + 6) - (-9x⁴ - 3y³ + 4z³ + 9)
= -2x⁴ - 4y³ + 4z³ + 6 + 9x⁴ + 3y³ - 4z³ - 9
= -2x⁴ + 9x⁴ - 4y³ + 3y³ + 4z³ - 4z³ + 6 - 9
= 7x⁴ - y³ + 0 - 3
= 7x⁴ - y³ - 3

There are some Chicken and rabbits in a cage. There are 20 heads and 62 feet in total, the question is: how many chicken and rabbits in the cage?
Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.
There were 450 people at a play. The admission price was $2 for adults and $1 for children. The admission receipts were $680. How many adults in how many children attended
Answer:
Adults= 110
Children= 340
Step-by-step explanation:
Given data
let adults be x
and children be y
x+y= 450----------1
2x+y=680---------2
from 1
x= 450-y
put this in 2
2(450-y)=680
900-2y=680
900-680=2y
220=2y
y= 220/2
y= 110
x+110= 450
x= 450-110
x=340
a cookie recipe at a bakery uses three cups of peanut butter chips for every two cups of chocolate chips that it uses. given the variables below which equation correctly relates the amount of chocolate and peanut butter chips needed to make a batch of cookies?
x: cups of chocolate chips needed for one batch
y: cups of peanut butter chips needed for one batch
A. y=1.5x
B. x= 5y
C. x=1.5y
D. y=5x
C. x = 1.5y
This is the answer
As, 3y/2x = 1.5y/x
So, by this ratio we get,
x = 1.5y

Find the values of x and y
Answer:
x = 2
y = 12
Step-by-step explanation:
In triangle ABD, CE is the mid segment.
Therefore, by mid segment theorem:
2(5x - 3) = x + 12
10x - 6 = x + 12
10x - x = 12 + 6
9x = 18
x = 18/9
x = 2
Since, DE = EA
2y - 4 = y + 8
2y - y = 8 + 4
y = 12
Paul and Quinn share some money in a ratio 3:2, Paul gets 60 more than Quinn, how much does Quinn get
Answer: 120
Step-by-step explanation:
3+2=5
Let x be the amount of money to be shared
Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x
Therefore
(3/5)x= (2/5)x + 60
(3/5)x - (2/5)x= 60
(x/5)=60
Cross multiply
x= 60*5=300
It means that Quinn’s share is (2/5)(300)= 120
The amount of money that Paul and Quinn have will be $180 and $120, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Paul and Quinn share some cash in a proportion of 3:2, Paul gets 60 a larger number than Quinn.
Let 'x' be the share of Paul and 'y' be the share of Quinn. Then the equation is given as,
x: y = 3: 2 ...1
x = y + 60 ...2
From equations 1 and 2, then we have
(y + 60) / y = 3/2
2y + 120 = 3y
y = 120
Then the value of the variable 'x' is given as,
x = 120 + 60
x = 180
The amount of money that Paul and Quinn have will be $180 and $120, respectively.

A right triangle is displayed.
36 in
60 in
The area of the right triangle is
Answer:
864 in²
Step-by-step explanation:
Use the pythagorean theorem to find the missing side.
36²+x²=60² (x is the missing length of the side)
1296 + x² = 3600
x² = 2304
x = 48
Then use the area of a triangle formula: base·height/2
Substituting 36 for the height and 48 for the base, we get:
48·36/2, which is 864.

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p
Answer:
p = 2
Step-by-step explanation:
Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.
Therefore, plug x = 2p - 1 & y = p in the above equation.
9p + 12 = 10(2p - 1)
9p + 12 = 20p - 10
12 + 10 = 20p - 9p
22 = 11p
p = 22/11
p = 2

QR ≈ 5.0
Step-by-step explanation:
Using the sine ratio in the right triangle
sin56° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{QR}{QS}[/tex] = [tex]\frac{QR}{6}[/tex] ( multiply both sides by 6 )
6 × sin56° = QR , then

Which of these expressions correctly represents the phrase “17 less than three times a number”?
Answer:
3n - 17
Step-by-step explanation:
This phrase includes subtraction (“less than”) and multiplication (“times”). We are multiplying a number (3) by the variable to create the term 3n. Subtraction is not commutative, so order does matter. 17 less than 3n means we have 3n and take 17 away: 3n - 17.
