Answer each question about the following arithmetic series: 12 18 24 30 . . . 198 what is the explicit rule for the arithmetic sequence on which the series is based? an = (n – 1)

Step-by-step explanation:

4.since two sides are congruent and two angles are equal so they are similar and we can say:

[tex] \frac{14}{42} = \frac{7}{x} \\ x = 21[/tex]

DF is 21

5.since two sides are congruent and two angles are equal so they are similar and we can say:

[tex] \frac{6}{9} = \frac{10}{x} \\ x = 15[/tex]

EF is 15

Answer:

16

Explanation:

Let "x" be the number

===========

→ integers less than 17 are 16, 15, 14, 13, 12, 11, 10, 9, ...

⇒ integers are whole numbers, not negative, does not include decimals or fractions.

So,

16 is the largest integer which is less than 17

Answer for 1st question:

The answer is A. 4/20

Step-by-step explanation:

The probability of landing on a vowel would be 2/5.

The probability of landing on an even number would be 2/4.

Now we just need to solve the probability of landing on a vowel and an even number.

2/5 x 2/4 = 4/20.

Thereore, the probability of landing on a vowel and an even number is 4/20.

Answer for 2nd question:

The answer is B. 1/20

Step-by-step explanation:

The probability of landing on a C would be 1/5.

The probability of landing on a 4 would be 1/4.

Again, we just need to solve the probability of landing on a C and a 4.

1/5 x 1/4 = 1/20.

Therefore, the probability of landing a C and a 4 is 1/20.

Using it's concept, it is found that there is a 0.79 = 79% probability that he or she is content with the vacation allowance.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 500 - 105 = 395 out of 500 employees are content with the vacation allowance, hence:

p = 395/500 = 0.79.

There is a 0.79 = 79% probability that he or she is content with the vacation allowance.

Answer:

8 bracelets

Step-by-step explanation:

Each time when we we cut the ribbon for making a ribbon, the length will be reduced. So, repeated subtraction is division.

To find the number of bracelets, divide the total length of the ribbon by the length required for making a bracelet.

Fraction division:

Use KCF method

Step1: Keep the first fraction

Step2: Change division to multiplication

Step3: Flip the second fraction

Number of bracelets = total length ÷ length required for making a bracelet.

                                  [tex]= 5\dfrac{1}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3}*\dfrac{3}{2}\\\\= 8[/tex]

The solution to the given equation is 4 and -4.

Fractions are the numerical values that are a part of the whole.

A whole can be an object or a group of objects.

The given equation is;

[tex]\rm \dfrac{y}{y - 4}- \dfrac{4}{y + 4}= \dfrac{32}{y^2- 16}[/tex]

A fraction is used to represent the portion/part of the whole thing.

The solution of the fraction is determined in the following steps given below.

[tex]\rm \dfrac{y}{y - 4}- \dfrac{4}{y + 4}= \dfrac{32}{y^2- 16}\\\\\rm \dfrac{y(y+4)-4(y-4)}{(y - 4)(y+4)}= \dfrac{32}{(y-4)(y+4)}\\\\y^2+4y-4y+16=32\\\\y^2=32-16\\\\y^2=16\\\\y=\pm 4[/tex]

Hence the solution to the given equation is 4 and -4.

Answer:

the answer is 12

Step-by-step explanation:

you toss the dice and coin let’s say it lands on 2 and heads there is one possibility. there is only 6 sides to the dice and 2 sides to a coin. 6 x 2 = 12.

Answer: coin = 26 sided die = 62 × 6 = 12

Step-by-step explanation: When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes(1 to 6). Putting these together means you have a total of 2×6=12 outcomes. The answer would be 12. Hope that helps!!

The sum of two given algebraic expressions is (9x-4)/(x²-4). Therefore, option C is the correct answer.

Addition of Algebraic Expressions is the process of collecting like terms and adding them. Identify and add the coefficients of like terms and sum them to find the final expression of given problems.

The given algebraic expressions are 7x/x²-4 and 2/x+2

Here, 7x/x²-4 can be written as 7x/(x+2)(x-2)

Now, 7x/x²-4 + 2/x+2

= 7x/(x+2)(x-2) + 2/x+2

= (7x+2(x-2))/(x+2)(x-2)

= (7x+2x-4)/(x²-4)

= (9x-4)/(x²-4)

Therefore, option C is the correct answer.

Answer:

[tex]\sf \dfrac{20}{32}=\dfrac{20}{32} \div 1=\dfrac{20 \div 4}{32 \div 4}=\dfrac{5}{8}[/tex]

Step-by-step explanation:

When reducing fractions to their simplest equivalent, we need to divide the numerator and denominator by their highest common factor.

Factors of 20:   1, 2, 4, 5, 10, 20

Factors of 32,    1, 2, 4, 8, 16, 32

Therefore, the highest common factor is 4.

Answer:

1/32

Step-by-step explanation:

1st step:  1/4 divided by 8, which is 1/4 divided by 8/1

Then for the 2nd step, you have to find the reciprocal of the 2nd fraction, so you just reverse it

2nd step:  1/4 X 1/8

3rd step.  1X1/4X8 = 1/32

You can also think of it like this.  He started with 4 pieces.  Each piece was then divided into 8 parts.  So 8X4=32 is the total number of pieces.  He's only eating 1 of those, so he's only eating 1/32
