Answer:
75
Step-by-step explanation:
You use the area of a triangle formula A= bh/2. If you substitute the numbers, it would be A (10 * 15)/2 which is 75
Answer:
<em>The unit rate for the price to the length of the fabric will be $8 per meter.</em>
Step-by-step explanation:
The two points on the graph of the line are: (1, 8) and (3, 24)
For finding the unit rate for the price to the length of the fabric, we just need to find the slope of that line.
Formula for finding the slope is:
, where
and
are two given points.
Here,
and ![(x_{2}, y_{2})=(3, 24)](https://tex.z-dn.net/?f=%28x_%7B2%7D%2C%20y_%7B2%7D%29%3D%283%2C%2024%29)
So, the slope of the line will be: ![m= \frac{24-8}{3-1}= \frac{16}{2}= 8](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B24-8%7D%7B3-1%7D%3D%20%5Cfrac%7B16%7D%7B2%7D%3D%208)
Thus, the unit rate for the price to the length of the fabric will be $8 per meter.
Funny, this looks like a complex graph, until you realize that the numerator can be written like (x+3)(x-9).
So really, this is a straight line f(x) = x-9.
But wait, there's a catch. x≠3, because that would divide by zero. So in your straight line, you have to draw a "hole" at (3,6)
Answer:
30 different types of tacos can Rico make.
Step-by-step explanation:
Given - The list below shows the different taco shells, fillings, and toppings sold at Rico's Taco Bar.
Taco Shells Fillings Toppings
Soft Chicken Cheese
Hard Beef Lettuce
Bean Sour Cream
Onions
Salsa
To find - How many different types of tacos can Rico make using one taco shell, one filling, and one topping?
Proof -
Given that,
There are 2 different types of Taco shells, 3 different type of fillings and 5 different types of toppings.
So, by the fundamental principal of counting,
Total types of tacos Rico made = 2 × 3 ×5 = 30
