The points are (130.5,5),(216.5,9) can someone please help me 4/18/18 - 1

Answers

Answer 1
Answer: First, we can use the slope formula to find the slope with the two points given:

m=(y2-y1)/(x2-x1)
m=(9-5)/(216.5-130.5)
m=4/86
m=2/43

Now, we can use the point slope form to find the equation of the line:

(y-y1)=m(x-x1)  *we can use either of the two points given*
(y-5)=(2/43)(x-130.5)
y-5=(2/43)x - 261/43
y=(2/43)x - 261/43 + 215/43
y=(2/43)x - 46/43

The second least value of fraction among 17/19, 10/13, 13/15, 2/9, 3/8 is _____

Answers

The second least value among the fractions  is (3)/(8)

Step-by-step explanation:

To find:

The least value we will change the fractions into decimal fractions

Given:

Fractions are (17)/(19), (10)/(13),(13)/(15), (2)/(9),(3)/(8)

Now resolving the above given fractions into their decimal value we get,

(17)/(19) = 0.8948

(10)/(13) = 0.7692

(13)/(15) = 0.8667

(2)/(9) = 0.2222

(3)/(8) = 0.375

Now, arranging them in ascending order we get,

(2)/(9) < (3)/(8)  < (10)/(13) < (13)/(15) < (17)/(19)

Hence, the second least value is (3)/(8)

Answer: 3/8

Step-by-step explanation:

To solve this question, convert to decimal by dividing the numerator by the denominator.

17/19 = 17 ÷ 19 = 0.89

10/13= 10÷13= 0.77

13/15= 13 ÷15= 0.87

2/9= 2÷9= 0.22

3/8= 3÷8=0.38

Therefore, least value of fraction is 2/9 while second least value is 3/8.

I hope this helps.

What number comes next in this pattern 2,4,8,16,32

Answers

2+2 = 4
4+4 =8
8+8 = 16
16+16 = 32
32+32 = 64
and so on :)
It would be 64 because it is multiplying 2 each time with that number. So, it would be 2 times 2 is 4. Then 4 times 2 is 8. Then 8 times 2 is 16. And 16 times 2 is 32. Then I did 32 times 2 and got 64.

Steve made a sign for his room that is shaped like a triangle. It is 4.5 feet long and 3 feet high. He wants to make another sign that is shaped like a triangle and similar to the first sign. The new sign will be 4 feet high. Part A Write a proportion that Steve can use to find the length, x, of the new sign.

Part B What is the length, in feet, of the new sign?

Answers

Answer:

Part A)    Using cross product x= 4.5*4/3

Part B )    x= 4.5*4/3= 18/3=6 Feet

Step-by-step explanation:

Length : Height

4.5        :     3

x           :     4

Part A)      Using cross product x= 4.5*4/3

Part B )    x= 4.5*4/3= 18/3=6 Feet
