The length of the line segment containing the points (1,7) and (5,5)
ArbitrLikvidat [17]

Answer:

True

Step-by-step explanation:

Let A denotes the point (1,7)

Let B denotes the point (5,5)

We are supposed to find The length of the line segment containing the points

Formula : d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

(x_1,y_1)=(1,7)\\(x_2,y_2)=(5,5)\\ d = \sqrt{(5-1)^2+(5-7)^2}\\ d = \sqrt{4^2+(-2)^2}\\ d = \sqrt{4^2+(-2)^2}\\d=4.47

So,The length of the line segment containing the points (1,7) and (5,5)  is 4.47 units is true.

Hence Option A is true

Productive use of machinery on a farm made it possible to decrease the number of tractors by 12. How many tractors does the farm
frez [133]
1. the answer is 24. think of x as the original amount, and y as the new amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y, which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to subtract 12, which would help you get 24 as your final answer. 

2. once again, create an equation. let's call team 1 x and team 2 y. team one has 1/4th as many as team 2, so that would be x=1/4y. An easier way to write that is 4x=y. after 6 people quit team two, that would be y-6. after the transfer, that would be y-6-12, and x+12 for the teams. they are equal after these, so y-6-12=x+12. solve this equation to get y-18= x+12. if you recall earlier, y was 4 times x, so substitute that into y to get 4x-18=x+12. Solve the equation to get 10 people on team one originally. your final answer is 10 people.

Diana is painting statues. She has \dfrac{7}{8} 8 7 ​ start fraction, 7, divided by, 8, end fraction of a liter of paint remaini
anzhelika [568]

Answer:

Number of statues that can be painted are 17

Step-by-step explanation:

Initially Diana has \frac{7}{8} liters of paint remaining.

Every statue requires \frac{1}{20} liters of paint for painting.

We have to find how many statues we will be able to paint with this remaining paint.

To get the number of statues,

Number of statues = \frac{Paint remaining}{Paint required for 1 statue}

number of statues = \frac{\frac{7}{8} }{\frac{1}{20} }

                               = \frac{35}{2} = 17.5

Since the number of statues is not an integer the maximum number of statues that can be painted are 17.

78 is 15% of what #?
nirvana33 [79]
1. 78 = 0.15x
    78 / 0.15 = x
    520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8                               | x + 1 | = 1

3x - 2 = 8      -(3x - 2) = 8            x + 1 = 1          -(x + 1) = 1
3x = 8 + 2      -3x + 2 = 8             x = 1 - 1           -x - 1 = 1
3x = 10           -3x = 6                  x = 0                 -x = 2
x = 10/3           x = -2                                             x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
    3y = 4x - 5
      y = 4/3x - 5/3
   slope = 4/3
