Answer:
y +4 = -5/14(x -7)
Step-by-step explanation:
The slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (1 -(-4))/(-7-7) = 5/-14 = -5/14
The point-slope form is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Filling in the given values, we have ...
y +4 = -5/14(x -7)
Answer:
4.50 + 1.25 = 5.75 x.15 = 0.8625
Round that to .86
$5.75 +.86(tip)
.86 cents
Step-by-step explanation:
There are an unknown number of possible outcomes. To figure this out all we need to do is multiply the amount of options per category to get the number of possible combinations.
In this case, there are 3 choices of food items and 3 choices of drinks.
Therefore, we need to multiply 3 by 3 to get the combinations.
3 times 3 equals 9
In conclusion, there are 9 possible combinations to be made from the choices presented.
To solve this problem, we begin by getting the whole area of the pizza. Because pizzas are depicted to be round, we will be getting the area of a circle.
The formula for getting the area of a circle: A = Pi * r^2
Pans are measured by their diameter, but we need the radius. The radius is simply half of the diameter.
8 / 2 = 4.
Now we have our radius.
Plug in our values.
A = 3.14 * 4^2
Take care of 4^2
A = 3.14 * 4^2 = 3.14 * 4 * 4 = 3.14 * 16
Now just multiply 3.14 and 16 together.
3.14 * 16 = <span>50.24
Ok, now we need to get the area for an individual slice of pizza. The pizza is cut up into 5 slices.
So, each slice would be 1/5 of the total area.
50.24 * 1/5
To make our lives easier, convert 1/5 into a decimal. Just divide the top by the bottom.
1 / 5 = 0.2
50.24 * 0.2 = </span><span>10.048
Now we need to round this to nearest inch.
10.048 </span>≈ 10
So, each slice of pizza has an area of 10 square inches.
