Answer:

Option 1 is correct.

Step-by-step explanation:

Given angle $\frac{11\pi}{18}$ . we have to find the quadrant and the reference angle.

Angle given is $\frac{11\pi}{18} i.e \frac{11}{18}\times 180^{\circ}=110^{\circ}$

Hence, the angle is 110° lies in second quadrant.

Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.

which is $\pi-\frac{11\pi}{18}=\frac{7\pi}{18}$

Hence, option 1 is correct.

A/2.8 x 2.8 "A over 2.8 times 2.8"

Jobisdone [24]

A/2.8 • 2.8
Division and multiplication are opposite of each other, meaning they cancel out.
This means that a/2.8 • 2.8 is a.
No matter what a is equal to, the answer is a itself.
Once a is divided by 2.8, it is then multiplied by 2.8, bringing us back to the original value of a.

Answer:
a/2.8 • 2.8 = a

What is surface area?

schepotkina [342]

The surface area is the area of the outside of a 3D shape for example, let’s say you have a cube, a cube has 6 sides, so you have to find the area of each side and then add it up, since it’s a cube you would technically have to find the area of one side and then just multiply it by 6, that would be the easiest way to do it

A pizza parlor offers 3 sizes of pizzas, 2 types of crust, and one of 4 different toppings. How many different pizzas can be mad

KonstantinChe [14]

Answer: The total number of pizzas that can be made from the given choices is 24.

Step-by-step explanation: Given that a pizza parlor offers 3 sizes of pizzas, 2 types of crust, and one of 4 different toppings.

We are to find the number of different pizzas that can be made from the given choices.

We have the COUNTING PRINCIPLE :

If we have m ways of doing one task and n ways of doing the second task, then the number of ways in which we can do both the tasks together is m×n.

Therefore, the number of different pizzas that can be made from the given choices is

$N=3\times2\times4=24.$

Thus, the total number of pizzas that can be made from the given choices is 24.
