Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

✦ First change the improper fractions to decimals:

✧ ⁵⁄₄ = 1.25

✧ -⁹⁄₅ = -1.8

✦ Then divide:

✧ 1.25 ÷ -1.8 = -0.69

So x would be -0.69 in decimal form.

Answer 2

Use the form y=mx +b for linear equations.Write the equation for the following relation.C = {(x, y): (6, 15), (8, 21), (10, 27), . . .}

Answers

I'm not sure if the answer is right, but here you go.

y=mx+b

'm' is for gradient of the line. First, calculate the gradient.

Let's use (6,15) and (8,21)

Gradient, m = $y_(2)$ - $y_(1)$
--------------
$x_(2)$ - $x_(1)$

= 21 - 15 = 6 = 3
----------- ----
8 - 6 2

Therefore, m = 3 . Now let's search 'b' .
Let's use (6,15) again. Substitute it into the equation.

y=mx+b
15 = 3 (6) + b
b = -3

Thus, the equation : y=3x -3

The diameter of a circle is 25cm and a chord of the same circle is 16cm. To the nearest tenth, what is the distance from the chord to the center of the circle

Answers

Answer:

9.6 cm

Step-by-step explanation:

The segment from the center to the chord forms a right triangle with one leg as half the chord and hypotenuse as the radius.

Use Pythagorean to find the length of the missing leg d

$d^2=(25/2)^2-(16/2)^2$
$d^2=(12.5)^2-(8)^2$
$d^2=92.25$
$d=√(92.25) =9.6$ cm (rounded)

Answer:

g = 6

Step-by-step explanation:

3.8g + 8 = 1.8g + 20

Subtract 1.8g from both sides;

2g + 8 = 20

Subtract 8 from both sides;

2g = 12

Divide both sides by 2;

g = 6

You can check if the value of g is correct by plugging in the value of g to the equation. If your check does not it doesn't mean your answer is not correct because sometimes it can be a no solution equation which means that there is no solution to the equation.

Check:

3.8(6) + 8 = 1.8(6) + 20

22.8 + 8 = 10.8 + 20

30.8 = 30.8

It means its correct
