What is the approximate area of the circle shown below? (The radius is 21cm)

A. 1385 cm2
B. 66 cm2
C. 5540 cm2
D. 132 cm

Answers

Answer 1

Answer:

The answer is A. 1385 cm2

Step-by-step explanation:

Use the formula A = pi times radius squared

Answer 2

Answer:

A. 1385 cm²

Step-by-step explanation:

Area of a circle is πr²

We know what the radius is, so all we have to do is plug it in.

π(21)²

π(21)²= 1385.44

Since it's approximate, it would just be 1385 cm²

Top equation opens down and the second opens up

Find the slope of the line through the points (13, 15) and (13, 19). Then find the slope of the line parallel and the line perpendicular.

Answers

Answer:

We must find the slope of the original line using slope formula*.

[tex]m = \frac{19 - 15}{13 - 13} = \frac{5}{0} = 0[/tex]

Because the given points have the same x-coordinate, the slope is 0.

Given that the original line doesn't have slope, the other two lines won't have one either.

The proof of AM being congruent to CM is as follows:

Given that,

ABCD is the ║gm

Diagonals AC and BD with M as the intersection point.

To prove:

AM ≅ CM

Proof:

In ΔAMD and ΔBMC,

∠M = ∠M                   (∵ Common)

AD = BC                       (∵ opposite sides of ║gm are equal)

∠ADM = ∠CBM           (∵ Alternate angle)

∵ ΔAMD ≅ ΔBMC

Thus, AM ≅ CM      (using AAS property).

Dwayne bought 11 shirts for the members of a club. He paid $7 for 10 shirts and $10 for 1 shirt. He also paid a one-time fee of $60 and $4 to embroider the club name on each shirt. Which expression could be used to determine how much he paid altogether for the 11 shirts?

Answers

Answer:

T = (7 * 10) + 10 + 60 + (4 * 11)

Step-by-step explanation:

The expression that can be used to determine the total cost would be the following ...

T = (7 * 10) + 10 + 60 + (4 * 11)

This expression sums up the cost of each shirt, the one-time fee, and the embroidery costs. Since 10 of the shirts cost $7 each then you need to multiply the cost by the number of shirts that cost that amount. The same goes for embroidery. Since there are a total of 11 shirts and each one costs $4 to embroider then you do 4 * 11

Two-thirds of the buses in the transit system run on natural gas, and the rest run on diesel. If 738 of the buses run on diesel, how many buses does the transit system have?

Answers

9514 1404 393

Answer:

  2214 buses

Step-by-step explanation:

Diesel buses constitute 1/3 of the total, so the total number of buses is 3 times the number of diesel buses.

  total = 3·738 = 2214

The transit system has 2214 buses.

What is 3.5=12s-55

Answers

Answer:

4.875 = s

Step-by-step explanation:

3.5=12s-55

Add 55 to each side

3.5+55=12s-55+55

58.5 = 12s

Divide each side by 12

58.5/12 = 12s/12

4.875 = s

Answer:

s = 4.875

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

3.5 = 12s - 55

Step 2: Solve for s

Add 55 to both sides:                    58.5 = 12sDivide 12 on both sides:                4.875 = sRewrite:                                           s = 4.875

Step 3: Check

Plug in s into the original equation to verify it's a solution.

Substitute in s:                    3.5 = 12(4.875) - 55Multiply:                               3.5 = 58.5 - 55Subtract:                              3.5 = 3.5

Here we see that 3.5 does indeed equal 3.5.

∴ s = 4.875 is a solution of the equation.
