2(x+2)-7=6x-4(1+x) solve for x
Answers
Answer:
x has no solution
Step-by-step explanation:
2x+4-7=6x-4-4x
2x-3=2x-4
-3=-4
Answer:
No solution
Step-by-step explanation:
2(x+2) -7 = 6x - 4(1+x) (Distribute 1st)
2x + 4 - 7 = 6x - 4 - 4x
2x - 3 = 2x - 4 (Combine like-terms)
2x - 2x = -4 + 3

Answer:
See Explanation
Step-by-step explanation:
Given
[tex]0 \le a \le 1[/tex]
[tex]8*a =b[/tex]
Required
Determine the true statement about b
The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite [tex]8*a =b[/tex]
[tex]b = 8 * a[/tex]
When a = 0
[tex]b = 8 * 0 = 0[/tex]
When a = 1
[tex]b = 8 * 1 = 8[/tex]
This means that:
For [tex]0 \le a \le 1[/tex]
Then [tex]0 \le b \le 8[/tex]
This means that: b is a number between 0 and 8

Answer:
7pi/theta = radius
Step-by-step explanation:
So we are using the arc length, central angle(in radians), and radius.
We know arc length, which is 7pi.
We don't know theta, which does not matter.
And finally, we don;t know radius, which is what we are looking for.
To find radius, we use:
arc length/theta=radius
Lets plug in our values:
7pi/theta=radius.
So the answer to the khan acadamy question is
7pi/∅
Here are some othr things that may help:
Radian * Radius = arc length
This solves for arc length
Here is another one:
Arc length/radius= radian
This solves for radians

find the inverse of the radical function y=-5+2/5√x
Answers
Answer:
y = (25/4)(x + 5)^2
Step-by-step explanation:
1. Interchange x and y, obtaining: x = -5 + (2/5)√y
2. Solve this result for y: x + 5 = (2/5)√y
Squaring both sides, we get (x + 5)^2 = (4/25)y
Multiplying both sides by (25/5) cancels out the (4/25) coefficient:
y = (25/4)(x + 5)^2 This is the inverse of the given function.

Find the volume of the cone round your answer to the nearest tenth
Answers
Answer:
209.43951 round to the nearest tenth is 209.44
Step-by-step explanation:
A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.
If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):
V = 1/3(PI*r squared * h )
The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.
Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.
V = 1/3(pi * r^2 * h)
= 1/3(pi * 2^2 * 3)
= 1/3(pi * 12)
= 1/3(37.7)
~ 12.6 cubic feet

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?
Answers
Answer:
3.5 cubic units
Step-by-step explanation:
First, find the volume of one cube
Use the cube volume formula, V = s³, where s is the side length
V = (1/2)³
V = 1/8 cubic units
Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes
28(1/8)
= 3.5
So, the volume of the prism is 3.5 cubic units

Answers
Explanation: Apply the pythagorean theorem (a^2 + b^2 = c^2) to get 11^2 + b^2 = 18^2. From that you can solve for b and you get the square root of 203.
Hope this helped! :)
Answer:
Pythagoras theorem.
hypotenuse²=base²+height²
(18)²=(11)²+h²
324=121+h
324 - 121 = h²
203=h²

A baker made 6 pounds of dough. He used 8 9 of the dough to make sandwich rolls. How much of the dough is left over?
Answers
Answer:
2/3 pound of dough is left
Step-by-step explanation:
Amount of dough available = 6 pounds
The amount used in making sandwich rolls = 8/9 of the total amount
= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]
Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]
Hence, 2/3 pounds of dough is left
Working alone, it takes Scott 16 minutes to inflate twenty balloons, Ashley can inflate the same twenty balloons in 15 minutes. Find how long it would take them if they worked together.
Answers
Answer:
7.74 minutes
Step-by-step explanation:
Scott's rate = 20 /16 = 1.25
Ashley's rate = 20 / 15 = 1.333
Combined rate = (1.25 + 1.3333) = 2.583333
Hence, time it will take to inflate 20 balloons :
Rate = number of balloons / time taken
2.583333 = 20 / time taken
Time taken = 20 / 2.583333
Time taken = 7.7419
It will take them approximately 7.7 minutes to inflate 20 balloons
