Mathematics

Masja [62]3 years ago

Answer:

100= 4 + 3 (100-1)

4+3 (99)

4 + 297 is 301

Step-by-step explanation:

The first row starts with 4 toothpicks, and they increase by +3 in each row.  The first tree is already accounted for which makes the 4 + 3, and why I have 100-1.  The teacher said the answer was correct but I doubted the equation.  Can you tell me if this is correct?

A chef uses a circular pan with a 24-inch diameter to make a pizza. What is the area of pizza
RUDIKE [14]

Answer:

<u>The area of a pizza made in that circular pan is 452.39 inches²</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Diameter of the circular pan = 24 inches

Radius of the circular pan = 24/2 = 12 inches

2. What is the area of the pizza?

Let's use the formula of the area of a circle, this way:

Area = π * r²

Substituting with the real values, we have:

Area = 3.1416 * 12²

Area = 452.39 inches²

<u>The area of a pizza made in that circular pan is 452.39 inches²</u>

ss7ja [257]

Answer:

The equation of the line would be D) y - 7 = -3(x -5)

Step-by-step explanation:

In order to find this, we must first start with the base form of point-slope form.

y - y1 = m(x - x1)

Now we put the slope in for m and the point in for (x1, y1)

y - 7 = -3(x - 5)
