Answer:
Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020shd dhdbxhd shx xhd dhddhdxbxbd hx shs shs xhd dhd zud hx dhd ddbd

Which point is in the graphed solution set of this system of inequalities?
{6x+2y>7
7x−2y<16
(4, 4)
(1, −10)
(2, 4)
(−2, 0)
Answer:
(2,4) is the correct answer
Step-by-step explanation:
In order to solve two inequalities, we have to graph the two inequalities on the graph. We have used the online graphing calculator "Desmos' for this purpose.
When two inequalities are graphed, the area that is common in both inequalities is the solution of the system.
We have to observe the graph to check if given points are in solution set of the system.
In the given points, (2,4) lie in the solution set as indicated in the picture.
Hence,
(2,4) is the correct answer

a bus is full of passengers. if you count them by either twos, threes, or fives, there is one left. if you count them by seven there will be none left. find the least number of passengers in the bus?
Answer:
91.
Step-by-step explanation:
The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.
2*3*5 = 30 but 31 is not a multiple of 7.
2*2*3*5 = 60 but 61 is not divisible by 7.
2*3*3*5 = 90 and 91 is divisible by 7.

A prism with a base area of 3 m2 and a height of 4 m is dilated by a factor of 3/2
What is the volume of the dilated prism?
Enter your answer, as a
decimal, in the box.
х
Answer:
The value of the new volume 'x' would be equal to 40.5 cm³.
Step-by-step explanation:
Given
base area = 3 m²height = 4mDilation by a factor scale of 3/2.We can determine the volume of the original prism by multiplying the area of the base by the height,
volume = (3 cm²)(4 cm) = 12 cm³
Dilation by a factor of 3/2 means that the dimensions of the new prism is 3/2 times that of the original object.
let 'x' be the volume of the new solid,
[tex]\frac{x}{12}=\left(\frac{3}{2}\right)^3[/tex]
[tex]\frac{x}{12}=\frac{27}{8}[/tex]
Multiply both sides by 12
[tex]\frac{12x}{12}=\frac{27\cdot \:12}{8}[/tex]
[tex]x=\frac{81}{2}[/tex]
[tex]x=40.5[/tex] cm³
Therefore, the value of the new volume 'x' would be equal to 40.5 cm³.

Step-by-step explanation:
Tracy found the length of GF. Her work is shown below.
Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 16, the length of line segment G E is 2 x, and the length of line segment B G is 8 x.
16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
GF = 2(32)
GF = 64
What error did Tracy make?
She used AG = 2EG, but the correct statement is 2AG = GE.
She found that x = 4, but the correct value for x is 2.
She used GF = 2BG, but the correct statement is BG = 2GF.
She found that GF = 64, but the correct value of GF is 8.
Answer:
C: She used GF=2BG, but the correct statement is BG=2GF

Step-by-step explanation:
RULE OF THE GAME:
If 6 spots are marked, a player wins if 4 or more of their spots are among the 6.
QUESTION:
Find the probabilities of having the following numbers of winning spots out of 6.
(A) 6 winning spots
6/6 = 1 In 8 decimal places, 1.00000000
(B) 5 winning spots
5/6 = 0.83333333
(C) 4 winning spots
4/6 = 0.66666667
(D) 3 winning spots

Total spots = 6
Selected spots = 4 or more
(a) Here are 6 winning spots, then
= [tex]\frac{6}{6}[/tex]
= 1 or,
1.00000000
(b) Here are 5 winning spots, then
= [tex]\frac{5}{6}[/tex] or,
= 0.83333333
(c) Here are 4 winning spots, then
= [tex]\frac{4}{6}[/tex] or,
= 0.66666667
(d) Here are 3 winning spots, then

Anybody know this if you do plz help
Answer:
1. m = -3 b = 2
2. m = 1/2 b = -1
3. m = -1 b = 79
4. m = 2 b = -2
5. y = -4x + 3
Step-by-step explanation:
1. the equation y=mx + b is used in number 1. m = slope and b = y intercept. so, because -3 is in the m spot, it is the slope, and because 2 is in the b spot, it is the y intercept.
2. apply the same concept as number 1. 1/2 is in the m spot, so it is the slope, and -1 is in the b spot, so it is the y intercept
3. To know the slope of the graph, you do rise/run. meaning, from one point on the graph, count how many times you go down to get to the next points, and then how many times you go over to get to the point. So, the slope of this line is -2/2, which is equal to -1. So, m = -1. To get the y intercept, take a pair of points from the graph (for example, (3,76)) and take the slope, and fill those in to the y = mx + b equation, and then solve for b. so, you get 76 = -1(3) + b. then do -1 times 3 and get -3. add 3 to both sides and you get b = 79.
4. apply the same concept on number 4 as you did number 3. Find rise/run, and you get 2/1, so m = 2. then take a point from the line (like point (0,-2)) and and the slope and fill it in to y = mx + b. you get -2 = -2(0) + b. so, b = -2.
5. simply fill in the information into the y = mx + b equation. remember, m is the slope, and b is the y intercept. so, you get y = -4x + 3

3а - 10 = a + 20
How do you do this help please it will mean a lot
Answer:
a=15
Step-by-step explanation:
2a-10=20
2a=30
a=15
can i have one brainliest plz
Answer:
a = 15
Step-by-step explanation:
I assumed you were trying to solve for A :)
3a - 10 = a + 20
1. Combine like terms (A's on side, numbers on the other).
3a - 10 = a + 20
-a -a
-----------------------
2a - 10 = 20
+10 +10
------------------------
2a = 30
Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.
[tex]\frac{2a}{2} = \frac{30}{2}[/tex]
This leaves you with a = 15, which is your answer if you are told to solve for A
