Step-by-step explanation:

Volume is three dimensional so it is measured in cubic units

Volume =(length)(width)(height)  [tex]\to[/tex] cubic centimeters

Area is two dimensional, it is measured in square units.

Area = (length)(width)  [tex]\to[/tex] square meter

Speed is derived from two basic quantities (length and time). It is measured  is meters per seconds.

Speed= distance/time   [tex]\to[/tex]  meter per second

Perimeter is distance around an object. It is measured in meters

Perimeter=2 (length)+2 (width)  [tex]\to[/tex] meter

Matching Quantities with Units

Answer:

Sequence: ordered list of numbers

Series: sum of the terms of a sequence

Arithmetic sequence: the difference between the terms is constant

Geometric Sequence: the ratio between the terms is constant

Step-by-step explanation:

The difference between a series and a sequence is that a sequence is a list of numbers that follow a pattern or rule.

For example

1, 3, 5, 7, 9...

[tex]a_n = 1 +2(n-1)[/tex]

On the other hand, a series is the sum of the terms of a sequence.

1 + 3 + 5 + 7 + 9 + ...+ n

[tex]\sum_{n=1}1 +2 (n-1)[/tex]

----------------------------------------------------------------------------------

The difference between an arithmetic sequence and a geometric sequence is that:

for the arithmetic sequences the subtraction of:

[tex]a_n - a_{n-1} = d[/tex]

Where d is a constant  called difference..

In the Arithmetic sequence the difference between the terms is constant

For the geometric sequences, it is satisfied that the quotient between two consecutive terms is:

[tex]\frac{a_{n-1}}{a_n} = r[/tex]

Where r is a constant value called common ratio

In geometric Sequence the ratio between the terms is constant

Final answer:

A sequence is an ordered list of numbers, while a series is the sum of the terms of a sequence. An arithmetic sequence has a constant difference between terms, while a geometric sequence has a constant ratio.

Explanation:

Difference Between Sequence and Series

A sequence is an ordered list of numbers following a specific pattern, while a series is the sum of the terms of a sequence. For example, in the sequence 2, 4, 6, 8, ..., each term is 2 more than the previous term. However, when these terms are added together, for instance, 2 + 4 + 6 + 8, we get a series.

Difference Between Geometric and Arithmetic Sequences

An arithmetic sequence is characterized by a constant difference between consecutive terms. For example, the sequence 3, 7, 11, 15, ... has a common difference of 4. On the other hand, a geometric sequence has a common ratio between consecutive terms, such as the sequence 2, 6, 18, 54, ... where each term is 3 times the previous term.

Answer:

The frequency of a number

Step-by-step explanation:

The mode in a data set provides how frequent a number in a data set appears.

For example, take the following data set:

1, 2, 2, 3, 3, 3, 3, 4, 5, 6, 7, 7, 8, 8, 8, 9, 10

The mode of this data set would be 3.

This is because 3 is repeated more frequently in the data set than any other number.

1, 2, 2, 3, 3, 3, 3, 4, 5, 6, 7, 7, 8, 8, 8, 9, 10

Step-by-step explanation:

Answer:

Bryan's answer is wrong because when we calculate the equation, the product will not be 36, since 2³ will be equal to 8, and 3² will be equal to 9, the product of 8 and 9 is 72, twice as much as the result we needed.

The correct equation here should be: 2² × 3² = 36

2² × 3² = 4 × 9 = 36

Answer:

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6}{y}[/tex]

Multiply both sides by y

y × sin30° = 6 ( divide both sides by sin30° )

y = [tex]\frac{6}{sin30}[/tex] = [tex]\frac{6}{\frac{1}{2} }[/tex] = 12

---------------------------------------------------------------------------------------

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex]

Multiply both sides by y ( y = 12 )

12 × cos30° = x

x = 12 × [tex]\frac{\sqrt{3} }{2}[/tex] = 6[tex]\sqrt{3}[/tex]

The slope is 2/-2, so -1. The y-intercept is 2. So, y=-x+2

Answer:

180 units²

Step-by-step explanation:

Let's find the length of the dashed line (which is the length of the trapezoid).  Use the Pythagorean Theorem:

7² + h² = 25², or h² = 625 - 49 = 576.  Thus, h = √576 = 24.

The average width of the trapezoid is:

         (7+4) + 4

w = ---------------- = 15/2

               2

The area of a trapezoid is (average width of trapezoid)(length of trapezoid), and here that comes to:

Answer:

[tex]\frac{1}{6}[/tex]

Step-by-step explanation:

In probability, "AND" means "multiplication" and "OR" means "addition".

Here, we are looking for probability of number greater than 4 "AND" probability of heads

so we find the individual probabilities and "multiply".

There are 6 numbers in a cube and number greater than four are 5 & 6, so 2 numbers. Hence

Probability of number greater than 4 is  2/6 = 1/3

Now,

In coin there is only head and tail, so probability of coming up heads is 1/2

Now we multiply both:

1/3 * 1/2 = 1/6

Hence

probability that a number greater than four is rolled and the coin comes up heads is 1/6

Answer: It equals y to the twentieth power.

Step-by-step explanation: when you have a power to a power, like this example, it's essentially saying, y to the power of 4 times y to the power of four times times y to the power of 4 times y to the power of 4 times y to the power of 4, so y to the fourth is being repeated 5 times, so just multiply 5*4 to get 20.

Answer:

measure of angle R is 75.897° or 75.90°.

Step-by-step explanation:

To solve use the formula Sin A/ a= Sin B/ b. our angle A is 52°, opposite it is side a so 26. Let angle R be our B so opposite it is b which measure 32.

sin 52°/26 = Sin B/32, cross multiply

32 (sin 52°) = 26 Sin B, multiply both side by 1/26

32 (sin 52°)/26 = Sin B

32 (0.78880107536...)/26 = Sin B

0.969593891... = Sin B

Sin^-1 (0.969593891..) = B

B = 75.89703075 or Angle R is 75.90°

The 2nd triangle has a bigger area, because since it has 2 sides that are equal to the first and its 3rd side is larger than the 1st triangle, it would have larger area, because it would have to have a larger area to have a larger side.

Answer:

Which triangle has a bigger area:  

1. A triangle with sides measuring 300, 400, and 500.

2. A triangle with sides measuring 300, 400, and 700.

Step-by-step explanation:

The second triangle has the largest area, because although the two triangles have two sides with the same size, the third is larger in the second triangle, 700 of the second, versus 500 of the first, and hence the area is also greater than in the first.

Answer:

$42.40

Step-by-step explanation:

The horizontal axis is in fractions.

The three lightest are two  [tex]\frac{5}{8}[/tex] pounds & one  [tex]\frac{6}{8}[/tex] pounds. Each cost $4.40 per pound.

So cost = 4.40(5/8+5/8+6/8) = $8.8

Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.

cost = [tex]4.80(1+1\frac{1}{8}+1\frac{1}{8}+1\frac{1}{8}+1\frac{2}{8}+1\frac{3}{8})=33.6[/tex]

Hence, total cost =  8.8 + 33.6 = $42.40

Answer:

Step-by-step explanation:

You cannot get your money back once you lose cash since it's not connected to any bank or financial institution, unlike debit cards, credit cards, or checks.

The form of payment that you can lose and not get your money back is cash. When you lose cash, there is no way to trace it or stop it like you can with a check, debit, or credit card. This is because cash is not linked to any banking or financial institution, so no protections are in place to recover lost or stolen cash. On the other hand, if you lose a debit card, credit card, or check, you can immediately inform your bank or card issuer to freeze your account or cancel the check, thereby protecting your money.
