What times 3/8 equals 1 whole

Elis [28]

$\frac{8}{3}$ times $\frac{3}{8}$ equals 1

Solution:

Given expression is at what times $\frac{3}{8}$ equals the whole.

Whole means 1 in a fraction.

Let us take the number of times be x.

$x\times\frac{3}{8} =1$

Multiply by $\frac{8}{3}$ on both sides of the equation.

$x\times\frac{3}{8}\times\frac{8}{3} =1\times\frac{8}{3}$

$x\times\frac{24}{24} =1\times\frac{8}{3}$

$x\times\frac{24}{24} =\frac{8}{3}$

$x\times1 =\frac{8}{3}$

$x =\frac{8}{3}$

Hence the fraction $\frac{8}{3}$ times $\frac{3}{8}$ equals 1.

The table shows the outputs, y, for different inputs, x: Input (x) 6 12 15 25 Output (y) 14 15 15 16 Part A: Do the data in this

cluponka [151]

Answer:

Part A: No it is not a function

Part B: The equation

Part C: x = 3

Step-by-step explanation:

Part A - The table:

Input (x) Output (y)

6 14

12 15

15 15

25 16

This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.

Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.

y = 7(6) -15

y = 42 - 15

y = 27

The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.

Part C: To find when y = 6, set it equal to 6 and solve for x.

6 = 7x - 15

21 = 7x

3 = x

HEEEELP PLEASE<br> I dont understand

lesya [120]

Answer:

Step-by-step explanation:

$\dfrac{y}{x}=a\to y=ax\\\\\text{We have}\ x=1,\ y=0.5.\\\\\text{Substitute:}\\\\a=\dfrac{0.5}{1}=0.5\\\\\text{Therefore}\ y=0.5x$

Look at the picture.

Definitions:

$\sin\theta=\dfrac{y}{r}\\\\\cos\theta=\dfrac{x}{r}\\\\\tan\theta=\dfrac{y}{x}\\\\\cot\theta=\dfrac{x}{y}$

We have the point (-5, -12) → x = -5, y = -12.

Calculate r:

$r=\sqrt{(-5)^2+(-12)^2}=\sqrt{25+144}=\sqrt{169}=13$

Substitute to the formula of sin:

$\sin\theta=\dfrac{-12}{13}=-\dfrac{12}{13}$

Answer: a.
