A pitcher contains 3.85 L of milk. Anna adds 0.475 Lof
chocolate syrup to make chocolate milk.
How many liters of chocolate milk are in the pitcher?

Answers

Answer:

[tex]Volume = 4.325 L[/tex]

Step-by-step explanation:

Given

[tex]Initial = 3.85L[/tex]

[tex]Additional= 0.475L[/tex]

Required

Determine the volume of the chocolate milk

Since, the mixture produces a chocolate milk, then the volume is the addition of milk in the pitcher and the chocolate syrup.

i.e.

[tex]Volume = Initial + Additional[/tex]

[tex]Volume = 3.85L + 0.475L[/tex]

[tex]Volume = 4.325 L[/tex]

Hence, there are 4.325 liters of chocolate milk in the pitcher

Answers

Answer:

relation

Step-by-step explanation:

First of all, all functions are relations, but not all relations are functions.

A function is a relation where one element in the domain is paired exactly with one element of the range.

A relation assigns one element of the domain to one or more elements of the range.

The range is any set of ordered pairs, while the function is a set where the group of pairs do not share the same first coordinate.

Hi there!

The altitude of a triangle is always perpendicular to the base, therefore:

5x° must equal 90°.

Solve for x:

5x = 90

5x / 5 = 90 / 5   ----> x = 18

KL is equal to  2x - 5, so plug the value of x into the equation:

KL = 2(18) - 5

KL = 36 - 5   ---> KL = 31

A median bisects the base, therefore:

A single fair die is tossed. Find the odds in favor of rolling a number greater than 5

What are the odds in favor of rolling a number greater than 5?

Please help

Answers

Answer:

[tex]1 : 5\ or\ \frac{1}5[/tex]

Step-by-step explanation:

Given that:

A single fair die is tossed.

First of all, let us learn about a fair die.

A fair die is a 6 sided die numbered from 1, 2, 3, to 6 and each side has an equal probability of occurring OR we can say each side is equally likely to occur.

So, probability of rolling a number greater than 5 has only one possible outcome i.e. 6.

And total number of outcomes are 6.

So, probability of rolling a number greater than 5 = [tex]\frac{1}{6}[/tex]

Probability of not rolling a number greater than 5 = [tex]\frac{5}{6}[/tex]

Odds in favor of rolling a number greater than 5 = Probability of rolling a number greater than 5 : Probability of not rolling a number greater than 5

[tex]\dfrac{1}{6} :\dfrac{5}{6} = \bold{1:5}\ or\ \bold{\dfrac{1}{5}}[/tex]

Using the probability concept, the odds of rolling a number greater than 5 is 1 :5

The odd of a particular experiment is defined thus :

Number of possible outcomes greater than 5 : number of possible below or equal to 5

Sample space = {1, 2, 3, 4, 5, 6}

Outcomes greater than 5 = {6} = 1

Outcomes below or equal to 5 = {1, 2, 3, 4, 5} = 5

The odds equals to 1 : 5

Is the following sequence a geometric sequence? If so, find its common ratio. 6,24,96,384,1536,…

Answers

Answer:

The given sequence is a geometric sequence and the common ratio is 4

Step-by-step explanation:

A geometric sequence is a sequence in which the next term is obtained by multiplying the previous term with a ratio r.

Given sequence is:

6,24,96,384,1536,…

Here

a1 = 6

a2 = 24

a3 = 96

a4 = 384

a5 = 1536

The common ratio is the ratio between consecutive terms of a geometric sequence.

If the common ratio of a sequence is same, then the sequence is a geometric sequence.

So,

[tex]r = \frac{a_2}{a_1} = \frac{24}{6} = 4\\r = \frac{a_3}{a_2} = \frac{96}{24} = 4\\r = \frac{a_4}{a_3} = \frac{384}{96} = 4\\r = \frac{a_5}{a_4} = \frac{1536}{384}= 4[/tex]

As the common ratio is same, the given sequence is a geometric sequence.

Hence,

The given sequence is a geometric sequence and the common ratio is 4

Answers

Answer:

The number of pizzas sold during A- lunch is 64

Step-by-step explanation:

Let us solve the question using the ratio method

∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3

∵ There were 48 nachos sold

→ By using the ratio method

→ Pizza  :  Nachos

→  4        :   3

→  x        :  48

→ use the cross multiplication

∵ x × 3 = 4 × 48

3x = 192

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{192}{3}[/tex]

"The poker hand straight consists of five cards having consecutive denominations (but can have varying suits). What is the probability to be dealt a stright from a deck of 52 cards

Answers

Answer:

The probability of dealing with a straight from a deck of 52 cards = 0.00394

Step-by-step explanation:

An ace must occur to have a straight, the Ace can either be high or low which can appear at the beginning or near the end. The rank of straight for an ace to occur range from 2,3,4,5,6,7,8,9,10.

If a suit is already at hand, and we have the opportunity to select four suits.

The number of possible straight = 4⁵ × 10

= 10240

Thus, the probability to deal with a straight = [tex]\dfrac{10240}{^{52}C_5}[/tex]

The probability to deal with a straight = [tex]\dfrac{10240}{\dfrac{52!}{5!(52-5)!} }[/tex]

The probability to deal with a straight = [tex]\dfrac{10240}{\dfrac{52!}{5!(47)!} }[/tex]

The probability to deal with a straight = [tex]\dfrac{10240}{2598960}[/tex]

The probability to deal with a straight = 0.00394
