Answer:

1.72r²

Step-by-step explanation:

total Rectangle area = 4r*2r = 8r²

total circles area = 2(π r²) = 2*3.14*r² = 6.28r²

then:

the area of the shaded region:

= 8r² - 6.28r²

= (8-6.28)r²

= 1.72r²

Answer:

2r²(4 - π)

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of rectangle - area of 2 circles

The rectangle has a length of 4r and a width of 2r , then

A = (4r × 2r) - (2πr²)

   = 8r² - 2πr² ← factor out 2r² from each term

    = 2r²(4 - π)

Answer: X = 8.5

Step-by-step explanation:

2x = 17

divide by 2

x = 8.5

By solving the value we get the value of x that is equal to 8.5.

[tex]\to[/tex] 2x=17

[tex]\to[/tex]  x=[tex]\frac{17}{2}[/tex]

[tex]\to[/tex] x=8.5

Answer:

x=5

Step-by-step explanation:

Step 1: Flip the equation.

−2x−9=−19

Step 2: Add 9 to both sides.

−2x−9+9=−19+9

−2x=−10

Step 3: Divide both sides by -2.

Exact Form:

x = 9/17

Decimal Form:

x = 0.52941176…

Edit: "but what are the steps to get 9/17"

1. Move all terms containing x to the left side of the equation.

2. Divide each term by −17 and simplify.

Step-by-step explanation:

Answer: False

Step-by-step explanation: Let's review the idea of graphs.

For a graph to be linear, it must be a straight line.

To determine whether a given graph is a function,

we use the vertical line test.

The vertical line test tells us that if a vertical line is drawn on a graph,

and hits the graph in more than one place, the graph is not a function.

In fact, this definition tells us the only type of linear graph

that will fail the vertical line test, and that's a vertical line.

Any vertical line that we draw will be both linear and not a function.

One possible graph could be x = 2.

Any vertical line will fit this description.

m= -5/4

Answer:

21

Step-by-step explanation:

Let x = $1 bill

Let y = $5bill

Translating the word problem into an algebraic equation;

For the total number of bills;

[tex] x + y = 47[/tex] .........equation 1

For the total number of tips;

[tex] x + 5y = 131[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making x the subject in equation 1:

[tex] x = 47 - y[/tex] .......equation 3

Substituting "x" into equation 2;

[tex] (47 - y) + 5y = 131 [/tex]

Simplifying the equation, we have;

[tex] 47 + 4y = 131 [/tex]

[tex] 4y = 131 - 47 [/tex]

[tex] 4y = 84 [/tex]

[tex] y = \frac {84}{4} [/tex]

y = 21 (For the $5 bills).

Therefore, Anthony received 21 pieces of the $5 bills.

To find x;

Substituting "y" into equation 3;

[tex] x = 47 - 21[/tex]

x = 26 (For the $1 bill).

Yes, quadrilateral ABCD is rectangle.

Step-by-step explanation:

This is because by looking at the terminology of ABCD, there are 4 variables in total together. This is also because when you see 4 variables together as one, it is a 4 sided quadrilateral.

Answer:

i dont get what you are trying to say is their a graph u can show

Step-by-step explanation:

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line

Answer:

c

You would earn $637

Equation: (4,800x6.5%)+325

Step-by-step explanation:

6.5%= 0.065

So 4800 times 0.065 is 312.

Then you add 312 to the weekly salary of 325

325+312= 637

Answer:

B and D

Step-by-step explanation:

The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.

If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.

Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.

Answer:

67/18 is 3.72 as a decimal.

Step-by-step explanation:

I know this because, to turn a fraction into a decimal, you must divide the numerator by the denominator.

67 ÷ 18 = 3.72

Therefore, 3.72 is my answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. (x - 3)(x + 7) = 0

  By zero product property,

  (x - 3) = 0 ⇒ x = 3

  (x + 7) = 0 ⇒ x = -7

2. (2x + 6)(x - 7) = 0

   2(x + 3)(x - 7) = 0

   By zero product property,

   (x + 3) = 0 ⇒ x = -3

   (x - 7) = 0 ⇒ x = 7

3). (4x - 2)(x + 4) = 0

   2(2x - 1)(x + 4) = 0

   (2x - 1) = 0 ⇒ x = [tex]\frac{1}{2}[/tex]

   (x + 4) = 0 ⇒ x = -4

4. (5x - 1)(3x + 9) = 0

   3(5x - 1)(x + 3) = 0

   By zero product property,

   (5x - 1) = 0 ⇒ x = [tex]\frac{1}{5}[/tex]

   (x + 3) = 0 ⇒ x = -3

5. (x - 8)(x + 2) = 0

   By zero product property,

   (x - 8) = 0 ⇒ x = 8

   (x + 2) = 0 ⇒ x = -2

Answer:
