Answer:

The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm

The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm

The area of a circle is given by \pi × square of radius

Area = 3.142 × 7.96×7.96 = 199.0821 square cm

Answer:

the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters

The following are the answers.

a = Commutative property of multiplication.

b = Identity property of multiplication.

c = Associative property of multiplication.

d = Inverse property of addition.

e = Identity property of multiplication.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

a.

x ⋅ 4 y = 4 x ⋅ y

This is the commutative property of multiplication.

a . b = b . a

b.

100 ⋅ 1 = 100

This is the identity property of multiplication.

a . 1 = a

c.

x (3 ⋅ 2x) = (x ⋅ 3) ⋅ 2x

This is the associative property of multiplication.

(a x b) x c = a x (b x c)

d.

3+(−3)=0

This is the inverse property of addition.

e.

−8 . (1/−8) = 1

This is the identity property of multiplication.

Thus,

The following are the answers.

a = Commutative property of multiplication.

b = Identity property of multiplication.

c = Associative property of multiplication.

d = Inverse property of addition.

e = Identity property of multiplication.

Answer and Step-by-step explanation:

When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:

[tex]a^{x} * a^{y} = a^{x+y}[/tex]

When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:

[tex]a^{x} / a^{y} = a^{x-y}[/tex]

When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:

[tex](a^{x)^{y} } = a^{xy}[/tex]

When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:

[tex](ab)^{x} = a^{x} b^{x}[/tex]

Step-by-step explanation:

Product means to multiply 2 numbers and for this question its 9x4. The devided by 6 part is just divided from 6. so (9x4)/6

Hope this helped!

The given expression can be written as the product of 9 and 4 divided by 6. Option D is correct.

Given that,
To write the expression (9 x 4 ) / 6 in statement.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,

(9 x 4) / 6
(9 x 4) consist of multiplication, imply a product of 9 and 4

and, ()/ 6 shows the division of product by 6
So,
(9 x 4) / 6 can be stated as the product of 9 and 4 divided by 6.

Thus, the given expression can be written as the product of 9 and 4 divided by 6. Option D is correct.

Answer:  The 6 burgers cost $40.20 and each burger costs $6.70.

Step-by-step explanation:

If she gave $50  to the waitress and received back $9.80 as a change, then subtract $9.80 from $50  to find the original price of the 6 burgers.

50 - 9.80 = 40.20  This means the 6 burgers cost $40.20 and to find how the price of each burger, divide 40.20 by 6.

40.20/6 = 6.70

Answer:

[tex]\displaystyle y=8x[/tex]

Step-by-step explanation:

We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.

So, we will first need to determine the slope. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are two points.

We have three points: (1, 8), (2, 16), and (3, 24).

Let’s pick two. We can use (1, 8) and (2, 16).

So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{8}{1}=8[/tex]

So, our slope is 8.

Now, we can determine the equation using point-slope form:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is our slope and (x₁, y₁) is a point.

We know that the slope is 8, so we will substitute 8 for m.

We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:

[tex]\displaystyle y-8=8(x-1)[/tex]

Solve for y. Distribute the right:

[tex]\displaystyle y-8=8x-8[/tex]

Add 8 to both sides:

[tex]\displaystyle y=8x[/tex]

And we have our equation.

Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.
