All you need to do is use the formula to solve. What I do is I plug in the information that I know, and then I just solve. In this case it would be:

V= (4)
- pie(3.14)*4.8(cubed)

Explain the steps for writing an equation of a line that passes through (4,7) and has a slope of 1/2

Marat540 [252]

Answer:

The equation would be y = 1/2x + 5

Step-by-step explanation:

To find this equation, we start by using point slope form, and then plugging the slope in for m and the point in at (x1, y1).

y - y1 = m(x - x1)

y - 7 = 1/2(x - 4)

And now we solve for y.

y - 7 = 1/2(x - 4)

y - 7 = 1/2x - 2

y = 1/2x + 5

Crayola makes 3 red crayons for every 2 brown crayons. On Tuesday, their factory made 1,000 more red crayons than brown. How man

miskamm [114]

Answer:

They make 2000 brown crayons on that day.

Step-by-step explanation:

Given:

Crayola makes 3 red crayons for every 2 brown crayons.

On Tuesday, their factory made 1,000 more red crayons than brown.

Now, to find the number of brown crayons they make that day.

Let the numbers of brown crayons be $x.$

So, the number of red crayons = $1000+x.$

As given, 3 red crayons for every 2 brown crayons.

So, the ratio is 3:2.

Thus, 3 is equivalent to 2.

So, 1000+ $x$ is equivalent to $x.$

Now, to get the number of brown crayons by using cross multiplication method:

$\frac{3}{2} =\frac{1000+x}{x}$

By cross multiplying we get:

$3x=2000+2x$

Subtracting both sides by 2 $x$ we get:

$x=2000.$

Therefore, they make 2000 brown crayons on that day.

Can u make a triangle with 2.1 in., 4 in.,7.9 in.

Alex777 [14]

No, the Triangle Inequality Theorem states that two sides of a triangle always add up to more than the third side. however, 2.1+4 < 7.9. this means that a triangle can't be made

Lets say the person works 8 hours a day, 25 days per month
Then he earns $10.5x8x25 = $2100 per months.

Lets assume that you should spend no more than 30 percent of your income on housing, then the maximum he can pay is 30% of $2100 = $630
