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

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.

Hi there! Let's start off with PEMDAS. It would appear that there are no parentheses or exponents, so let's get to that | Absolute Value |. -4 + 0 is -4, but because it's an absolute value, it'll become 4. The problem should read as 6/2*4. Let's move on to Multiplication/Division. 6/2 is 3, and multiplying 3 by 4 is 12.

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).
