How Many Dots Would Be In The 7th Picture ?

Answers

Answer 1

Answer: 28 dots

Step-by-step explanation: In this pattern,

we can see the the first figure is just 1 dot.

The second figure has a new row on the bottom with 2 dots.

The third figure has a new row on the bottom with 3 dots

and the fourth figure has a new row on the bottom with 4 dots.

So continuing with this pattern,

the next figure will have a new row with 5 dots,

the next will have a new row with 6 dots,

and the next will have a new row with 7 dots.

So in the 7th picture, we will have 7 + 6 + 5 + 4 + 3 + 2 + 1 dots.

This simplifies to 28 dots.

In the text box below, write a brief summary about the similarities and differences between Inequality Notation, Set-Builder Notation, and Interval Notation.

Answers

Answer and Step-by-step explanation:

Differences:

Interval notation is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example set of all real numbers can be described in interval notation as 0 ≤ x ≤1.  Interval notation press the solution set to equality, and it is important to express solution sets in calculus. Set builder notation is a mathematical notation for describing a set by its elements, and their member satisfies' properties.It describes the elements of a set instead of listing the element. For example the set {1, 2, 3, 4, 5, 6, 7, 8, 9} is written in builder notation will be {x/x is a counting number less than 10}.Inequality notation is a relation that makes a non equal comparison between two numbers. Set are also defined by using some inequalities like >, <, ≤, ≥. These are called inequality notations.

Similarities:

The purpose of inequality notation, set builder notation, and interval notation is the same because these notations used to describe a set and the characteristics of each element of a set. When a set is representing in set builder notation, it defines characteristics of elements.  If the set is represented in interval notation, we need to know the upper and lower bound set. In inequality notation, the set is described by the graph on a number line.

For how many games is the total cost of bowling equal for the two bowling establishments? Family bowling game $4, shoes $1. Knight owl bowling game $3.75, shoes $2.

Answers

Answer: If you play 4 games, the price will be the same in the two establishments.

Step-by-step explanation:

Ok, in Family Bowling we have:

$4 per game, plus $1 per shoes (the shoes are paid only one time).

Then, the price for X games, is:

Pa(X) = $4*X + $1.

In Knight Owl Bowling we have:

$3.75 per game and $2 for the shoes, the price for X games will be:

Pb(X) = $3.75*X + $2.

Now, if we want to pay the same in both establishments, we have:

Pa(X) = Pb(x)

$4*X + $1 = $3.75*X + $2

Now we should solve this for X.

$4*X - $3.75*X = $2 - $1 = $1

($4 - $3.75)*X = $1

$0.25*X = $1

X = $1/$0.25 = 4.

If you play 4 games, the price will be the same in the two establishments.

What is the value of the expression below when y=8 and z=8? 10y-3z

Answers

Answer:

56

Step-by-step explanation:

We are given the expression:

10y-3z

and asked to find the value when y=8 and z=8. Therefore, we must substitute 8 in for both y and z.

10(8)-3(8)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition and Subtraction.

Multiply 10 and 8.

(10*8) -3(8)

80-3(8)

Multiply 3 and 8.

80 - (3*8)

80- 24

Subtract 24 from 80.

(80-24)

56

The value of the expression 10y-3z when y=8 and z=8 is 56.

t23=36754

Answer:

The 23rd term is 2806.

Step-by-step explanation:

The other answerer has used the formula but i'm answering from the assumption that T1 to T4 are correct.

Each term is the sum of n terms of an arithmetic series with first term a1 = 12 and common difference d = 10.

Sum of n terms = (n/2)[2a1  + d(n - 1)]

So the sum of 23 terms =

= 23/2 (2*12 + 10 * 22)

= 11.5 * 244

= 2806.

The volume of a cone is 200.96 cubic yards. What is the radius of the cone if the height is 12 yd? Use pi =3.14 and round your answer to the nearest hundredth.

Answers

Answer:

If I'm doing the problem correctly, the radius should be 4 yards.

Step-by-step explanation:

You work the problem backwards. Multiply 200.96 by 3, since it's a cone, so you're working with the volume of what a cylinder would be with the same dimensions. Then divide by the height (12 yd), then divide by pi. You should end up with 16, and 4 squared equals 16. Work the problem forwards from there to check.

4 squared is 16. 16 times 3.14 is 50.24. 50.24 times 12 is 602.88. 602.88 divided by 3 is 200.96.

The formula for the area of a triangle is A = 1/2bh, in which b represents the length of the base and h represents the height. If a triangle has an area of 328 mm^2 and the height is 16 mm, what is the measure of the base?

Answers

Answer:

b = 41 mm

Step-by-step explanation:

From the question

Area of a triangle is given by

[tex]A = \frac{1}{2} bh[/tex]

where

b is the length of the base

h is the height

From the question

Area = 328 mm²

height = 16 mm

Substitute the values into the above formula and solve for the height

We have

[tex]328 = \frac{1}{2} \times 16b \\ 328 = 8b[/tex]

Divide both sides by 8

We have the final answer as

b = 41 mm

Help with brothers math homework?I can't help because I forgot how to do this​

Answers

Answer:

See below.

Step-by-step explanation:

The range of a graph is the span of y-coordinates the graph covers.

From the graph, we can see that the graph covers all y-values between the values of y=-8 and y=7.

Therefore, the range is all of the numbers in between them including them.

In interval notation, this is:

[tex][-8,7][/tex]

We use brackets instead of parentheses because we include the numbers.

And in set notation, this is:

[tex]\{y|-8\leq y\leq 7\}[/tex]

Answer:

Hey there!

The range is the possible y values.

Thus, we see here that the range is all numbers from -8 to 7.

Factor of 3x-3a+xy-ay

Answers

Answer:

(3 - y) & (x - a) are the factors

Step-by-step explanation:

3x-3a+xy-ay

=> 3x - xy - 3a - ay

=> x(3 - y) - a(3 - y)

=> (3 - y)(x - a)

(3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.

Here, we have,

given that,

the expression is : 3x-3a+xy-ay.

now, we have,

To factor the expression 3x - 3a + xy - ay, we can group the terms as follows:

3x-3a+xy-ay

=> (3x - 3a) + (xy - ay)

Now, let's factor out the common factors from each group:

=> 3(x - a) + y(x - a)

Notice that both terms now have a common factor of (x - a).

We can factor out this common factor:

=> (x - a)(3 + y)

Therefore, the factored form of the expression 3x - 3a + xy - ay is (x - a)(3 + y).

Hence, (3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.
