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

Distance from the tip to the middle of the turbine = Radius of the circular turbine
Radius of the circular turbine = 32 meters
Circumference of the circular turbine = distance the turbine will travel in one revolution
We know that :
[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]
Circumference of the circular turbine :
[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]
[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]
[tex] =\tt \frac{44}{7} \times 32[/tex]
[tex] =\tt \frac{44 \times 32}{7} [/tex]
[tex] =\tt \frac{1408}{7} [/tex]
[tex]\color{plum} =\tt 201.06 \: m[/tex]
▪︎201.06 m can be roughly rounded off to 200.96.
▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m
▪︎Therefore, the correct option is (A) 200.96

Answer:
Step-by-step explanation:
The answer is 1 2 and 4
The correct options are 1 and 3.
The expression can be written as 4n + 7, involving multiplication and addition.
Given is a verbal expression "Four times a number increased by seven"
We need to convert it into algebraic expression.
So,
Replace "a number" with the variable, n.
This means we replace the phrase "a number" in the expression with the variable "n".
So, the expression becomes "Four times n increased by seven," which can be written as "4n + 7."
The two operations are multiplication and addition.
This option is correct.
The expression involves two operations: multiplication and addition.
We have "Four times a number" which means we multiply the number by 4, and then "increased by seven" means we add 7 to the result.
So, the expression can be written as 4n + 7, where 4n represents the multiplication and +7 represents the addition.
The expression is written as 4n + 7.
This option is correct. The given expression "Four times a number increased by seven" can be written as 4n + 7, where 4n represents the multiplication of the number by 4 and +7 represents the addition of 7 to the result.
So, the correct options are 1 and 3.

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.

Step-by-step explanation:
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
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.

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

The circle graph represents the number of teenagers at a high school who play video games. If 1,619 students go to the school,
about how many students do not play video games?
A. 72 students
B. 360 students
C. 454 students
D. 1.165 students
Answer:
C. 454 students
Step-by-step explanation:
Students who play video games = 259°
Students who don't play video games = 360° - 259°
= 101°
Students who don't play video games = 101°/360° * 1,619
= 0.2805555555555 × 1,619
= 454.219 students
Approximately 454 students

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
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

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.

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.
