The measurement of the distance from the tip of the slice of pizza to the crust is the radius.

The diameter of the pizza is 12 inches and the circumference is 37.7 inches

A slice of pizza is cut from the middle of the pizza to the crust. It is therefore cut from the middle of the pizza (circle) to the edge of the pizza (circle).

This is the radius because the radius is the straight - line distance from the edge of the middle of a circle to the edge.

If the radius is 6 inches, the diameter is:

= radius x 2

= 6 x 2

= 12 inches

The circumference is:

= π x diameter

= 22/7 x 12

= 37.7 inches

Answer:

If a house need 50 hours to paint, it will cost $3000

Step-by-step explanation:
--- According to the problem, $500 is the cost for supplies, which means that for every house, that cost will be there. In other words, this payment never changes no matter the house. So far you pay $500

--- Now, the problem says that you pay $50 for each hour of labor. Since the house need 50 hours, we will multiply 50 (the cost) by 50 (the hours) = 2500.

--- Now we put the payments together. 500 + 2500 = 3000. So it will cost $3000 to paint a house that need 50 hours.

The Z score of the individual with IQ 90 is -0.67.

It is given that the scores are Normally distributed.

The mean given is 100 while the standard deviation is 15.

Let the IQ distribution be X.

Hence X follows a Normal distribution X~N(100, 225)

where

100 = mean

225 = standard deviation

To find the Z score we need to convert the following into the standard normal distribution.

To do that we need to follow

Z = ((x - μ) / σ)

here

μ = mean of the distribution = 100

σ = standard deviation of the distribution = 15

x = 90

Hence the Z score is

Z = (90 - 100) / 15

= -10/15

= -0.67

The volume of the cylindrical Pringles chip can is 1508 cm³

From the question, we are to determine the volume of cylindrical can

The volume of a cylinder is given by the formula

V = πr²h

Where V is the volume of the cylinder

r is the radius

and h is the height

From the given information,

Diameter = 8 cm

But,

Radius = Diameter / 2

Therefore,  

r = 8 / 2 = 4cm

h = 30 cm

Thus,

Volume of the cylindrical can = π× 4² × 30

Volume of the cylindrical can = π× 16 × 30

Volume of the cylindrical can = 480π cm³

Volume of the cylindrical can = 1507.96447 cm³

Volume of the cylindrical can ≈ 1508 cm³

The question has not specified other conditions so we have assumed it by cases and solved it

Case 1 -

“Everything” allowed, means that we are considering solutions like “AA” and “BA, AB”

If this is the case then there are => 26 x 26 = 676 Combinations,

Case 2-

No repetition allowed

Here, we are excluding cases like “AA, BB” etc so here we have

26 x 25 = 650 as our answer

Case 3-

no repetition allowed + unique set every time, So

here we will have ²⁶C₂ (this is basic combinatorics formula )

= (26 x 25)/2

= 325 combinations possible

Case 4 -

When one lists their ages and their heights as ordered pairs (age, height), the statement that is true is D. It is both a relation and a function.

A relation between two sets is a collection of ordered pairs that each contain one object from the other set. If the ordered pair (x,y) is in the relation and the object x is from the first set and the object y is from the second set, the objects are said to be related. A relation is a type of function.

A function is a relation that states that there should be only one output for each input (or) we can say that a function is a special type of relation (a set of ordered pairs) that follows a rule, i.e., every X-value should be associated with only one y-value.

Answer: -33/5

Step-by-step explanation:

The price of ticket will be $26 approximately in 2009 using the concept of the linear equation and slope.

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is fairly simple (x and y). When attempting to solve systems of two linear equations, this form is also very helpful.

Here,

The line has 2 points,

(2001,18) and (2005,22)

m=(22-18)/(2005-2001)

m=1

y-y1=m(x-x1)

y-18=x-2001

x-y=1983

(2009,y) is on that line,

2009-y=1983

For the given triangle ΔABC the value of (x + y) would be 7 cm.

What is an equilateral triangle?

An equilateral triangle is a triangle with the same length on all three sides. An equilateral triangle is also equiangular in Euclidean geometry; that is, all three internal angles are congruent to each other and are each 60°.

Given data:

Length of AB = (3x + 2) cm.

Length of AC = 11 cm.

Length of BC = (2y + 3) cm.

The property of an equilateral triangle says that all sides of an equilateral triangle are equal.

then we can write,

                  AB = AC

               3x + 2 = 11

                3x = 11 - 2

                3x = 9

                x = 9/3

                x = 3 cm

Also, BC = AC

        2y + 3 = 11

        2y = 11 - 3

        2y = 8

          y = 8/2

          y = 4 cm

So the value of (x + y) = 3 +4

                                    = 7 cm.

Hence, For the given triangle ΔABC the value of (x + y) would be 7 cm.

Answer:

12 tables per classroom.

Step-by-step explanation:

We will assume that the teacher uses all of the 4/5 oz of paint.  We can find how many samples of 1/30 oz are contained in the 4/5 oz by dividing:

(4/5)÷(1/30) = (4/5)*(30/1)

(4/5)*(30/1)  = (120/5)

(120/5) = 24 samples of 1/30 oz paint in (4/5) oz total paint.

Each of the 2 Pre-K classrooms have the same number of tables, so we can divide 24 samples by 2 to find the number of tables in each classroom,

*24 samples/2 classrooms) = 12 tables/classroom

The function represented by the graph has an equation of f(x) = |x - 3| + 5

From the question, we have the following graph that can be used in our computation:

The graph is an absolute value graph

As a general rule, an absolute value is expressed as

y = |x - h| + k

In this case, the vertex is

Vertex = (h, k)

As a general rule, the vertex of a function is the minimum point on the graph

On the given graph, the minimum point is (3, 5)

This means that

(h, k) = (3, 5)

Substitute the values (h, k) = (3, 5) in the equation y = |x - h| + k

So, we have the following representation

y = |x - 3| + 5

Rewrite the equation as a function

f(x) = |x - 3| + 5

Hence, the equation of the graph represented by the figure is f(x) = |x - 3| + 5

The distance between two cyclists after 45 minutes as described in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.

It follows from the task content that the distance between the two cyclists after 45 minutes is to be determined from the given parameters.

Given; the speed of the first cyclist is; 12 miles per hour, while the speed of the second cyclist is b miles per hour greater than that of the first.

The speed of the second cyclist is therefore; (b + 12).

On this note, since the distance covered by each cyclist is given by;

Distance = Speed × Time where, Time = 45 minutes = 0.75 hours.

Therefore, the total distance between the two cyclists can be determined from the expression as follows;

7 + 0.75 (12) + 0.75 (b + 12).

Therefore, the distance between the two cyclists as required in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.

Writing only p = 5 is a mistake since p = 0 is also a solution of the  quadratic equation

Given the quadratic equation: p² −5p = 0

p² −5p = 0

p(p−5) = 0

p = 0 or p−5=0    

p = 0 or p = 5

Jada made mistake in the  3rd step instead of him to break the equation into two parts and then equate them to zero i.e he neglected the part where p = 0 and only make use of p-5 = 0

Since the equation has two solutions, p = 0 and p = -5. Therefore, writing only p = 5 is a mistake because when p = 0 is substituted into p² −5p = 0, it also gives 0
