Answer: The correct option is

(B) $s=\dfrac{25}{12}.$

Step-by-step explanation: We are given to find the value of s from the following equation :

$\dfrac{1}{2}+\dfrac{2}{5}s=s-\dfrac{3}{4}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the value of s, we must solve the given equation.

The solution of equation (i) is as follows :

$\dfrac{1}{2}+\dfrac{2}{5}s=s-\dfrac{3}{4}\\\\\\\Rightarrow s-\dfrac{2}{5}s=\dfrac{1}{2}+\dfrac{3}{4}\\\\\\\Rightarrow \dfrac{5-2}{5}s=\dfrac{2+3}{4}\\\\\\\Rightarrow \dfrac{3}{5}s=\dfrac{5}{4}\\\\\\\Rightarrow s=\dfrac{25}{12}.$

Thus, the required value of s is $\dfrac{25}{12}.$

Option (B) is CORRECT.

If a spring stretches 6 meters when a 7-kilogram weight is attached to it, how much will it stretch when a 42-kilogram weight is

Zinaida [17]

Answer:

Step-by-step explanation:

This is a simple proportion problems.

7 kilogram weight attache to a spring stretches = 6 meters

1 kilogram would stretch = 6/7 m

Therefore 42 kilograms would stretch = (6/7 x 42)meters

= 36 meters.

Answer:(7/8 - 4/5)^2 = 9

1600

= 0.005625

Step-by-step explanation:

Subtract: 7

- 4

= 7 · 5

8 · 5

- 4 · 8

5 · 8

= 35

- 32

= 35 - 32

= 3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - seven eighths minus four fifths = three fortieths.

Exponentiation: the result of step No. 1 ^ 2 = (3

) ^ 2 = 32

402

= 9

1600

In words - three fortieths squared = nine one-thousand six-hundredths.

Which list represents the independent values on this graph? 0, 100, 250, 200, 300, 350, 400, 500, 650, 700, 750 1, 2, 3, 4, 5, 6

A scatter plot is used to relate the dependent and the independent values

The list of independent values is:1, 2,3, 4,5,6,7,8,9,10

<h3>How to determine the independent values</h3>

The ordered pairs on the scatter plot are:

(x,y) = (1, 100), (2,250) , (3,200) , (4,300), (5,400), (6,350), (7,500) , (8,650) , (9,700) and (10,750).

Remove the y values

x = 1, 2,3, 4,5,6,7,8,9,10

The x values represent the independent values

Hence, the list of independent values is:1, 2,3, 4,5,6,7,8,9,10
