Can somebody explain area to me

Area is how many unit squares can fit in a figure. For example, if you imagine a grid with many squares, one square would be 1 square unit. Two squares would be 2 square units. If you have a rectangle with 27 squares that would be 27 square units.
But it would be really hard and time-consuming to count all 27 of those squares. So you can use a formula. Length * width = area
Length of 9 times width of 3 = 27 square units.

Now different shapes/figures have different formulas for area. In a triangle, the formula is (1/2)*base*height, or (base*height)/2. This is because a triangle is half of a rectangle, so you multiply the base and height and divide all that by 2.

To find width it would have to be Length x Width=Area

Write a linear function f with the values f(2)=4 and f(−7)=9. A function is f(x)=

ale4655 [162]

Answer:

f(x) = -5/9 x + 5 1/9

Step-by-step explanation:

f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)

f(x) = mx + b

m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9

for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9

f(x) = -5/9 x + 5 1/9

check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9

the cafeteria staff made sandwich each sandwich had either rye or white bread either ham or turkey and either cheese or no chees

nata0808 [166]

The complete question is

"The cafeteria staff made sandwiches. Each sandwich had either rye or white bread, either ham or turkey, and either cheese or no cheese. The staff made an equal number of each type of sandwich.

The sandwiches were placed on a tray. Without looking, Mary will choose a sandwich.

What are the chances that Mary will get a sandwich with cheese?"

The chances of Mary getting a sandwich with cheese is 1/2.

<h3>How to calculate the number of different ways?</h3>

The number of different sandwiches is calculated by multiplying all of the possibilities for each material being used.

rye or white bread: 2 options

ham or turkey: 2 options

cheese or no cheese: 2 options

So the number of different sandwiches = 2*2*2 = 8.

4 have cheese and 4 have no cheese, as the staff made an equal number of each type of sandwich.

So, The chances of Mary getting a sandwich with cheese is 4/8 = 1/2.
