What is the slope of the line that passes through these points?

Natasha2012 [34]

Answer:

The slope is 6.

Step-by-step explanation:

For this, you will want to use the slope formula.

m = y2 - y1 / x2 - x1

m = 14 - 2 / 19 - 17

m = 12 / 2

m = 6

. Mr. Donut wants to paint a donut on the wall of his restaurant. The diameter of the outside edge of the donut will be 22 inche

KATRIN_1 [288]

Answer:

The area needed to be painted is approximately 301.44 square inches.

Step-by-step explanation:

The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:

$A =A_{g}-A_{s}$ (Eq. 1)

Where:

$A$ - Total area of the donut, measured in squared inches.

$A_{g}$ - Area of the greater circle, measured in square inches.

$A_{l}$ - Area of the lesser circle, measured in square inches.

By using the definition of the area of the circle, we expand the equation above:

$A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s}$ (Eq. 1b)

If we know that $\pi = 3.14$ , $D_{ext} = 22\,in$ and $A_{s} = 78.5\,in^{2}$ , the area needed to be painted is:

$A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}$

$A \approx 301.44\,in^{2}$

The area needed to be painted is approximately 301.44 square inches.

Car A and car B are traveling at different speeds. Car A can travel 175 miles in the same time it takes car B to travel 125 mile

slega [8]

Answer:

The speed of car B is 50 mile per hour

Step-by-step explanation:

Given as :

The Distance travel by car A = 175 miles

The Distance travel by car B = 125 miles

The Time taken by both car A and B is same = T hours

Let The speed of car B = S mile per hour

So, The speed of car A = ( S + 20 ) mile per hour

Now, Time = $\frac{Distance}{Speed}$

So , For Car A ,

T = $\frac{175}{(S + 20 )}$

For Car B ,

T = $\frac{125}{(S}$

So, $\frac{175}{(S + 20 )}$ = $\frac{125}{(S}$

Or, 175 × S = 125 × ( S + 20 )

Or, 175 S - 125 S = 125 × 20

Or, 50 S = 2500

∴ S = $\frac{2500}{(50}$

I.e S = 50 mph

And S + 20 = 50 + 20 = 70 mph

The speed of car A = 70 mph

The speed of car B = 50 mph

Hence The speed of car B is 50 mile per hour Answer
