Answer:

$\frac{-3x}{14}$

Step-by-step explanation:

$x+\frac{1}{2}x+7y = 0\\$

$1.5x + 7y = 0$

$7y = -1.5x$

$y = \frac{-1.5x}{7}$

$= \frac{-3x}{14}$

A car travels 1.9 miles from Point A to Point B. The car then turns at Point B and travels 1 mile to Point C, before heading bac

If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.

b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°

F the sphere shown above has a radius of 5 units, then what is the approximate volume of the sphere?

bogdanovich [222]

<h3>Given:</h3>

Radius= 5 units

<h3>To find:</h3>

The approximate volume of the given sphere.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{4}{3}\pi{r}^{3}}$

Let's substitute the values according to the formula.

Let's solve!

$V=\frac{4}{3}×\pi×{5}^{3}$

$V=523.59878 \: {units}^{3}$

Now, well have to round off to the nearest hundredth.

$\boxed{V=523.6 \: {units}^{3}}$

<u>Hence,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>sphere</u><u> </u><u>is</u><u> </u><u>523.6</u><u> </u><u>cubic</u><u> </u><u>units</u><u>.</u>

Note: If your using π as π you'll get this answer.

Having trouble with this one help appreciated

Hoochie [10]

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

$y=kx$

The number 'k' is called the constant of proportionality.

Given the equation

$y=3.50x$

as

$y=kx$

so

$k=3.50$ ∵ $y=kx$

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.
