Hi, I need some help with this question about the circumference of a circle. Help would be greatly appreciated :)

Answer:

109.9

Step-by-step explanation:

It is asking for circumfrence right?

c=pi(d)

c=1/2(3.14)(70)

c=109.9

Sorrry if i am wrong

To find the length of the semicircular driveway with a diameter of 70 ft, calculate the circumference using the formula C = π * diameter.

To find the length of the driveway:

Given the diameter is 70 ft, the radius is half of that, which is 35 ft.

The formula for the circumference of a circle is C = π * diameter.

Substitute the values to find the length, C = 3.14 * 70 ft = 219.8 ft.

Answer: Multiply width x length x depth to calculate volume (cubic inches).

Step-by-step explanation:

Answer:48 cubic inches

Step-by-step explanation:

Its a box which means it has 4 equal side so therefore

12x4 = 48

Answer:

Uhh? You can't factor this!

Step-by-step explanation:

So.. we see that the last term, the constant, (the +5) is positive, which means the two terms (the a and b on the (x+a)(x+b) must be either both positive or both negative).

We try positive, and we end up with

(x+1)(x+5)

x^2 + x + 5x + 5

x^2 + 6x + 5

which is not what we want!

We try negative, and we end up with

(x-1)(x-5)

x^2 -x -5x +5

x^2 -6x +5

which is also not what we want!

This isn't factorable!

You can always complete the square or utilize the quadratic equation, but you can't factor it.

Step-by-step explanation:

Answer:

This is the graph. It is a normal square root function, but translated down 6 units.

Answer:

Option C.

Step-by-step explanation:

The standard form of a quadratic function is

[tex]ax^2+bx+c=0[/tex]         ... (i)

The given equation is  

[tex]0=5x-4x^2-2[/tex]

It can be rewritten as

[tex]-4x^2+5x-2=0[/tex]        ... (ii)

On comparing (i) and (ii), we get

[tex]a=-4,b=5,c=-2[/tex]

Hence, the correct option is C.

Answer:

a=-4, b = 5, c = -2

Step-by-step explanation:

Answer:

y = -3/2x+3

Step-by-step explanation:

We first need to find the slope using

m = (y2-y1)/(x2-x1)

    = (9-0)/(-4 -2)

       9/-6

   =-3/2

We will use the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

y = -3/2x+b

Substitute a point into the equation

0 = -3/2(2) +b

0 = -3+b

b = 3

y = -3/2x+3

Answer:

Function

Step-by-step explanation:

A function is any equation that doesn't have a repeat of any outputs. Since no principal can be a principal of more than one school, it's a function.

Each school having one principal is an example of a mathematical function because there is a one-to-one relationship between schools (inputs) and principals (outputs), meeting the definition of a function with a unique output for each input.

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. When we consider the example of schools and principals, we can apply this concept to determine if it represents a function. If each school (input) has one and only one principal (output), it satisfies the criteria for a function. This is because there is a one-to-one relationship between schools and principals. No school has more than one principal, hence adhering to the definition of a function with a domain (schools) and a range (principals).

Furthermore, the concept of functions is foundational to various aspects of school systems, which goes beyond mathematics and extends into the social functions of education. For instance, schools act as socialization agencies teaching respect for authority and conformity to law, which is a manifest function. This educational function aligns with the structure of authority within schools where each principal is the head of their respective school.

Answer:

Step-by-step explanation:

If Jody chooses the ginger ale, the probability that she also chooses root beer from her selection is 1/3.

Jody has four bottles of soft drink: one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. The question is, if she chooses the ginger ale, what is the probability she also chooses root beer?

Since Jody has already chosen the ginger ale, she now has to choose 2 more bottles from the remaining three (cola, root beer, and orange).

There are 3 choose 2 ways (which is 3 ways) for Jody to pick her remaining bottles.

Only one of these combinations includes root beer (ginger ale, root beer, and one of the others).

Therefore, the probability that she also chooses root beer, given she has chosen ginger ale, is 1/3.

Answer:

8 cups

Answer:

8

Step-by-step explanation:

Once you convert 4 gallons to cups it equals 64.

Once you convert 14 quarts to cups it equals 56.

Now you subtract 64-56 and it equals 8.

Answer:

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss=$26

Step-by-step explanation:

Let the number of documents put together and prepared for mailing by Bill =x

Bill receives 25 Cents=$0.25 for every document

Therefore for x documents, Bill should receive: $0.25x

If Bill prepared 2000 documents for mailing

x=2000

The amount he should receive = $0.25 X 2000 =$500

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss

=500-474

=$26

Bill should have received a gross pay of $500 for preparing 2,000 documents.

Bill works for the Stuff It Mailing Service and receives 25 cents for each document he prepares for mailing. Last week, Bill prepared 2,000 documents for a local department store. To find his correct gross pay, we can multiply the number of documents he prepared by the amount he earns per document: 2,000 documents × $0.25 per document = $500. Therefore, the correct gross pay for Bill should be $500.

Answer:

this equation would have one solution

Step-by-step explanation:

Answer:

375 cm2

Step-by-step explanation:

The new area of the triangle will be 187.5 square centimeters.

To find the area of a triangle, you can use the formula A = ½ x base x height. Given that the area of the triangle is 15 square centimeters, we can set up the equation as 15 = ½ x base x height. We are told that all the dimensions of the triangle are multiplied by 5, so the new base and height will be 5 times the original dimensions. Substituting these values into the equation, we get 15 = ½ x (5 x base) x (5 x height). Simplifying the equation, we have 15 = 12.5 x base x height.

Therefore, the new area of the triangle is 12.5 times the original area, which is 15 x 12.5 = 187.5 square centimeters.

Answer:

(x-2)^2=36

Step-by-step explanation:

I got it correct on khan academy! but the layout is kind of confusing so when you put the answer in, the full thing will look like

(x+-2)^2=36

So all you have to type in is -2, and 36:)

The value of x=8,-4.

Write the equation in the form, such that c is on the right side.

Step 2: If a is not equal to 1, divide the complete equation by a such that the coefficient of x2 will be 1.

Step 3: Now add the square of half of the coefficient of term-x, (b/2a)2, on both sides.

Given equation:

x² - 4x - 32 = 0

Now, add and subtract (2)² we get

x² - 4x - 32 + 2² - 2² = 0

x² - 4x + 2²  - 32 - 2² = 0

(x-2)² -36=0

(x-2)²= 36

(x-2) = ±6

x= +6+2, -6+2

x=8,-4

To find the perimeter of a quadrilateral use the distance formula to find the length of each side, and then add the lengths so option (A) will be correct.

Perimeter is the addition of an external measure of sides it will always positive.

A perimeter is a length and has a degree of the unit as one.

For example

Perimeter of square =  side + side + side + side

Perimeter of circle = πd where d is dia of the circle.

To find the perimeter of the quadrilateral we need to find all four side and add them because the perimeter is nothing but the sum of external sides.

So,

By using the distance formula we can find the distance between two points or the distance of a side of a quadrilateral because coordinates are given.

Hence "Use the distance formula to find the length of each side, and then add the lengths"
