Answer:

The answer to your question is: Incorrect

Step-by-step explanation:

Sid is wrong because 26 is not a multiple of 3.

A number is multiple of three if the sum of its digits is multiple of three.

Example:

24 = 2 + 4 = 6 6 is a multiple of 3

27 = 2 + 7 = 9 9 is multiple of 3

but 26 = 2 + 6 = 8 8 is not a multiple of 3

A window is being replaced with tinted glass. The plan at the right shows the design of the window. Each unit length represents

PolarNik [594]

The answer is $911.68.

After a little research on the internet, I found the design of the window.
First, you need to find the area of the window which is a composite figure made up of a rectangle and a circle. So, the total area (A) is the sum of the area of the rectangle (A1) and the area of the circle (A2).

Area of the rectangle with length l and width w is:
A = l * w
According to the image, l = 5 ft and w = 4 ft.
A1 = 5 * 4 = 20 ft²

Area of the circle with radius r is:
A = r²π
According to the image, r = 2 ft.
A2 = 2² * 3.14 = 12.56 ft²

The area of the window is:
A = A1 + A = 20 ft² + 12.56 ft² = 32.56 ft²

The glass costs $28 per square foot, so to replace the glass will cost:
32.56 ft² * $28/ft² = $911.68

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

(1)

Here m = 6 and b = - 2, then

y = 6x - 2

(2)

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Here m = - 2 and b = 5, then

y = - 2x + 5 ← equation in slope- intercept form

Add 2x to both sides

2x + y = 5 ← equation in standard form

(3)

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (6, - 13) and (x₂, y₂ ) = (- 4, - 3)

m = $\frac{-3+13}{-4-6}$ = $\frac{10}{-10}$ = - 1 , then

y = - x + b ← is the partial equation

To find b substitute either of the 2 points into the partial equation

Using (- 4, - 3 ) , then

- 3 = 4 + b ⇒ b = - 3 - 4 = - 7

y = - x - 7 ← equation in slope- intercept form

Add x to both sides

x + y = - 7 ← equation in standard form

The attendance at two baseball games on successive nights was 74,000. The attendance on Thursday's game was 4,000 more than two-

nadezda [96]

Answer:

The answer is 53,333 rounded

Step-by-step explanation:

So you multiply 74,000 by 2/3 you get 49,333

Then you take that number and add 4,000 and you get 53,333 rounded.
