Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?


What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20

Ian needs to find the area of the shaded region shown below. Which statements can he use to find the answer? Select three options.

A circle with diameter 11 feet. Three-quarters of the circle is shaded.
The radius is 5.5 feet.
The area of the whole circle is A = (5.5) squared pi.
The area of the whole circle is A = (11) squared pi.
The area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).
The area of the shaded region can be found by multiplying the area of the whole circle by two-thirds as in A = two-thirds (pi times r squared).

What is the perimeter of the figure on the coordinate plane below?


Answers

Answer:

26 units

Step-by-step explanation:

im not sure if this will help but i counted the spaces and added the halves

The perimeter of the given figure on the coordinate plane is 56 units.

What is perimeter?

A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.

Now from given figure, the following length of the sides is given,

9 units

4 units

4 units

8 units

11 units

3 units

2 units

15 units

Now since we know that,

Perimeter = Sum of lengths of all the sides

⇒ Perimeter = 9+4+4+8+11+3+2+15

⇒ Perimeter = 56 units

Thus, the perimeter of the given figure on the coordinate plane is 56 units.
