3n+5-12n-8+6p
Answer
-9n-3+6p
Step-by-step explanation:
Answer:
-9n - 3 + 6p
Step-by-step explanation:
You have to remember that you can add or subtract only LIKE terms. In other words, you can't add 3n + 5, so separate them.
In this equation: 3n + 5 - 12n - 8 + 6p,
1. 3n - 12n
2. 5 - 8
3. 6p
= -9n - 3 + 6p
0.2(k + 2.4) = 3.2k. Please help me.
Answer:
k = 0.16
Step-by-step explanation:
First, use distributive property on the left side:
[tex]0.2(k+2.4)=3.2k\\0.2k+0.48=3.2k\\0.48 = 3k\\k = 0.16[/tex]
Answer:
k = 0.16
Step-by-step explanation:
Use distributive property, meaning individually multiply 0.2 to each number/variable within the parameters
0.2 × k = 0.2k
0.2 × 2.4 = 0.48
0.2k + 0.48 = 3.2k
You cannot add a number and a variable so instead we should isolate the variable
Subtract 0.2k from both sides
0.48 = 3.2k - 0.2k
0.48 = 3.0k
0.48 = 3k
Divide both sides by 3
0.16 = k

A teepee is designed to have a diameter of 10 ft and a volume of 366ft³ what is the height? A.15ft , b.14 ft, c 5ft, or 1 ft
Answer:
B. 14 ft approx
Step-by-step explanation:
Given data
A teepee has a conical shape
Diameter= 10ft
radius= 5 ft
Volume = 366ft³
Height = ????
The expression for the volume is
V= 1/3πr^2 h
substitute
366= 1/3*3.142*5^2*h
366= 1/3*78.55*h
366= 26.18h
h= 366/26.18
h=13.98 ft
h= 14 ft approx
Hence the Height is 14 ft approx
Answer:
14 ft

y. If x = 60 when
y = 75. find x when
y = 32.
Answer:
x=17
Step-by-step explanation:
Answer:
25.6
Step-by-step explanation:
find constant of variation ('k'):
y = kx
75 = 60k
k = 75/60 or 5/4
32 = 5/4x
cross-multiply:
5x = 128
x = 25.6

Which of the following values are solutions to the inequality 6≥4x−5?
Answer:
The solution to the inequality is:
[tex]6\ge \:4x-5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{11}{4}\:\\ \:\mathrm{Decimal:}&\:x\le \:2.75\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{11}{4}]\end{bmatrix}[/tex]
-5 and -6 are the solution values.
Step-by-step explanation:
Given the inequality
[tex]6\ge \:4x-5[/tex]
Let us solve the inequality
[tex]6\ge \:4x-5[/tex]
switch sides
[tex]4x-5\le \:6[/tex]
Add 5 to both sides
[tex]4x-5+5\le \:6+5[/tex]
Simplify
[tex]4x\le \:11[/tex]
Divide both sides by 4
[tex]\frac{4x}{4}\le \frac{11}{4}[/tex]
Simplify
[tex]x\le \frac{11}{4}[/tex]
Thus, the solution to the inequality is:
[tex]6\ge \:4x-5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{11}{4}\:\\ \:\mathrm{Decimal:}&\:x\le \:2.75\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{11}{4}]\end{bmatrix}[/tex]
In our case, we are given the values -6, 8, and -5
We have already determined that the solution is x ≤ 2.75.
Since the solution is x ≤ 2.75, so -5 and -6 come under the solution set because -5 and -6 are less than 2.75.
Hence, -5 and -6 are the solution values.
The graph of the solution of the inequality is also attached below.
The solutions to the inequality 6 ≥ 4x − 5 is x ≤ 11/4.
What is inequality?A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now the given inequality is,
6 ≥ 4x − 5
Adding 5 both the side we get,
6 + 5 ≥ 4x − 5 + 5
⇒ 11 ≥ 4x
Dividing both the side by 4 we get,
11/4 ≥ 4x/4
⇒ 11/4 ≥ x
or, x ≤ 11/4
this is the required solution of the given inequality.
Thus, the solutions to the inequality 6 ≥ 4x − 5 is x ≤ 11/4.

Circumscribe a circle about the given triangle.
Answer:
Step-by-step explanation:
To circumscribe a circle to a given triangle implies constructing a circle outside the triangle, so that it touches the three vertices of the given triangle externally.
The step requires bisecting two sides of the triangle so as to locate the center of the circle. Then with the center and one of the edges, draw a complete circle. The circles should be outside the triangle and passing through its three vertices.
The construction is as shown in the attachment to this answer.

(08.05)What conclusion can be determined from the dot plot below?
A dot plot showing five dots above 9, six dots above 10, three dots above 11, and one dot above 12.
The number of observations is 10.
The median of the data set is 10.
The mean of the data set is 15.
The range of the data set is 12.
Answer:
Option 2
Step-by-step explanation:
Go through until you find a true statement:
- The number of observations is 10
Count the number of data points. You should end up with 15, so this option is not correct.
-The median of the data set is 10
To find the median, you know that there are a total of 15 data points, so the median would be the mean of the 7th and 8th (because those are the middle numbers). If you look at the data points, the 7th and 8th points are at 10. The mean of 10 and 10 is just 10, so that means the median of the set is 10.
This is the correct answer.
If you want, you can also go through the other options and see that none of them work.

Answer:
The least common multiple of 8 and 12 is 24
Explanation:
Find and list the multiples each number until the first common multiple is found.
This is the lowest common multiple .
Multiples of 8
8, 16, 24, 32,40
Multiples of 12
12,24, 36,48
Therefore,
LCM of 8 and 12 is 24
Answer: The answer is 24
Step-by-step explanation: One easy way to find least common multiples is to take the large number and multiply it by increasing numbers (1,2,3,etc.) until a number is found that is also divisible by the smaller number.
In this case, we can multiple 12 by increasing numbers until we find a number that is also divisible by 8.

(1 Point)
300
330
180
500
17
Answer:
x = 800 and y = 330
Step-by-step explanation:
Let two numbers be x and y.
Sum of two numbers is 1130.
Their difference is 470.
So,
x+y=1130 ...(1)
x-y = 470 ...(2)
Add equation (1) and (2).
x+y+x-y = 1130+470
2x = 1600
x = 800
Put the value of x in equation (1)
800+y=1130
y = 1130-800
y = 330
So, the smallest number is 330 and the largest number is 800.

kayden mixed two solutions together which causes a chemical reaction and the solution becomes warm. which statement best describes what has happened
A. energy has been transformed from one form to another
B. energy has been created, where it did not exist before
C. the chemicals energy of the solution had been described
D. more energy has been created than has been destroyed
According to law of conservation of energy, the statement which best describes what has happened is that energy has been transformed from one form to another.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1812.
