Ans

Step-by-step explanation:

vidieo games are educational because it teaches kids about real life ,like how to avoid scammers,if you fall down get up , kindness and more

For their craft project during the first week of camp, the campers used clothespins to make miniature rocking chairs. To make 90

fenix001 [56]

1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.

We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.

x is the number of clothes pins for 1 chair

$\frac{90 chairs}{1080 clothespins} =\frac{1 chair}{x clothespins}$

Cross multiply to get

90*x= 1080*1

Divide both sides by 90 to isolate x

x = 12 clothespins

It takes 12 clothespins to make 1 chair.

Fine the exact distance between the line 6x-y=-3 and the point (6,2). Show your work. Explain your answer.

AVprozaik [17]

Answer:

$\sqrt{37}$ units

Step-by-step explanation:

If we draw a perpendicular from point (6,2) on the line 6x - y = - 3, then we have to find the length of the perpendicular.

We know the formula of length of perpendicular from a point $(x_{1}, y_{1} )$ to the straight line ax + by + c = 0 is given by

$\frac{|ax_{1} + by_{1} +c |}{\sqrt{a^{2}+b^{2}}}$

Therefore, in our case the perpendicular distance is

$\frac{|6(6)-2+3|}{\sqrt{6^{2} +(-1)^{2} } } = \frac{37}{\sqrt{37} } = \sqrt{37}$ units. (Answer)

(a) Find the value of xif 10, x and 30 are in A.P.

jekas [21]

Part A

<h3>Answer: x = 20</h3>

--------------------------------

Explanation:

AP = arithmetic progression, which is another way of saying arithmetic sequence.

Let d = common difference

first term = 10
second term = first+d = 10+d = x
third term = second+d = x+d = 30

Apply substitution like so

x+d = 30

10+d+d = 30 ... replaced x with 10+d

10+2d = 30

2d = 30-10

2d = 20

d = 20/2

d = 10 is the common difference

Therefore,

x = 10+d = 10+10 = 20

The AP {10,x,30} updates to {10,20,30}. We see the gap between terms is 10 units. All AP's have the same gap width between adjacent terms.

=============================================================

Part B

<h3>Answers: x = 10 and y = 14 </h3>

--------------------------------

Explanation:

We use the same ideas mentioned back in part A.

d = common difference = unknown for now

first term = 6
second term = first+d = 6+d = x
third term = second+d = x+d = (6+d)+d = 6+2d = y
fourth term = third+d = y+d = (6+2d)+d = 6+3d = 18

Hopefully you can see how each term builds up to form the next one. We'll solve that last equation like so

6+3d = 18

3d = 18-6

3d = 12

d = 12/3

d = 4

So we then can say:

x = 6+d = 6+4 = 10
y = 6+2d = 6+2(4) = 6+8 = 14

The arithmetic sequence {6,x,y,18} updates to {6,10,14,18}. There's a gap of 4 between each adjacent term.
