Answer: 51

Step-by-step explanation: A prime number is a number that is greater than 1 and it has two factors which are 1 and itself.

23 is a prime number because it has no other factors besides 1 and 23. In other words, there is no other number multiplied by a number than will equal 23 so we call it a prime number.

Answer:

[tex]w=-1[/tex].

Step-by-step explanation:

We have been given an equation [tex]2w-5(w+1)=3w+1[/tex]. We are asked the equation for w.

Using distributive property [tex]a(b+c)=ab+ac[/tex], we will get:

[tex]2w-5w-5=3w+1[/tex]

[tex]-3w-5=3w+1[/tex]

Subtract 3w from both sides:

[tex]-3w-3w-5=3w-3w+1[/tex]

[tex]-3w-3w-5=1[/tex]

Combine like terms:

[tex]-6w-5=1[/tex]

Add 5 on both sides:

[tex]-6w-5+5=1+5[/tex]

[tex]-6w=6[/tex]

Divide both sides by -6:

[tex]\frac{-6w}{-6}=\frac{6}{-6}[/tex]

[tex]w=-1[/tex]

Therefore, our required equation would be [tex]w=-1[/tex].

Answer:

A. 0.3 (With a line above the 3) ([tex]0.\overline{3}[/tex])

Step-by-step explanation:

The part of money used for the bus fare = [tex]\frac{1}{3}[/tex]

Upon division the value,

[tex]\frac{1}{3} = 0.33333333....333[/tex]

As this no. is a rational number with recurring decimal. It means that the number after the decimal repeats up to infinity.

Such recurring decimal numbers are represented with a bar or line over the recurring digits.

Thus the given number is represented as [tex]0.\overline{3}[/tex].

Answer: 6%

Step-by-step explanation:

If you turn 6% to a decimal (move it twice to the right) we get 0.06. If we multiply 0.06 and $750 we get $45, which is how much investment increased. Add $45 to $750 we get $795 ( which is the new value).

750×0.06= 45

45+ 750= 795

17/20 is the fraction of an hour Ernesto spent waiting for the bus

A fraction represents a part of a whole.

Given that Ernesto's bus arrived 51 minutes after he got to the bus stop

We need to find the fraction of an hour Ernesto spent waiting for the bus

We know that 1 hour has 60 minutes.

Ernesto's  waited 51 minutes out of 60 minutes or an hour.

So 51 minutes is the part and 60 minutes is the whole part

Then the fraction will be 51/60

51 and 60 are the multiples of 3.

Let us divide numerator and denominator by 3

17/20

Hence, 17/20 is the fraction of an hour Ernesto spent waiting for the bus

Answer:

The odds against winning the game is 3 to 1.

Step-by-step explanation:

*Probability states that it is the likelihood of something happening in the future.

*Its value lie between 0 and 1.

*complement of an event is that event that is not occurring .

Then, the probability of  Event A will not occur is denoted by P(A').

Given:

The probability of winning a particular game at game place is [tex]\frac{1}{4}[/tex]

or we can write this as P(X) = [tex]\frac{1}{4}[/tex] where X is winning a particular game  at game place.

To find the odds against winning the game:

P(X') = P(Not winning a game) = 1-P(X) = [tex]1-\frac{1}{4} = \frac{4-1}{4} =\frac{3}{4}[/tex]

Now, we have

the probability of winning is [tex]\frac{1}{4}[/tex] = 25%

and the probability of not winning is [tex]\frac{3}{4}[/tex] = 75%

Therefore, odds against winning is (chances against success) : (chances for success) =  3 to 1 or 3 : 1

The mini laptop is on sale for 40% off, the discount is 40% of the regular price then the discount could be 180 dollar.

Third party discount is the multiplication result of the maturity value of the original rate to the rate of interest and time period.

Thus, we get:

Third party discount = Maturity value × R × T (R in decimal form).

WE have been given that the laptop is on sale for 40% off, the discount is 40% of the regular price.

Since they are asking for the discount and not the discounted price.

Discount

= 40% ×$450

= ⅖ ×$450

= $180

Thus, the option c is correct.

When the boat has made 35 tours, the train will have made 56 tours, based on the ratio 8 train tours for every 5 boat tours.

The question involves calculating the number of train tours when a given number of boat tours is reached, utilising basic multiplication and ratios. Since there are 5 boat tours and 8 train tours per day, for every boat tour, there are 8/5 train tours. To find out the number of train tours when there have been 35 boat tours, we multiply 35 by 8/5 which equals 56.

Here is the table showing the boat to train tour ratios:

Boat Tours  5,10,15,20,25,30,35

Train Tours 8,16,24,32,40,48,56

Therefore, when the boat has made 35 tours, the train will have made 56 tours.

Step-by-step explanation:

Barney should get 2 as his answer.Ana's result implies  N = 2.Therefore, when Barney multiplies the same numberN  by 8, he should get 16 as his answer.

Ana's result implies that [tex]\( N \div 8 = 0.25 \).[/tex] To find the original number N we can multiply both sides by 8:

[tex]\[ N = 0.25 \times 8 = 2 \][/tex]

Therefore, the original number Nis 2. Now, Barney is asked to multiply the same number N by 8.

[tex]\[ \text{Barney's result} = N \times 8 = 2 \times 8 = 16 \][/tex]

Hence, Barney should get 16 as his answer.

In summary, Ana's division of N  by 8 resulting in 0.25 implies that the original number  N  is 2. When Barney multiplies this number by 8, he should get 16 as the final answer.

It's important to note that Ana's division and Barney's multiplication are inverse operations. Ana divided by 8, and to undo that operation, we multiply by 8. This concept is fundamental in algebraic reasoning, where operations can be reversed by applying their inverse operations. In this case, understanding the relationship between division and multiplication allows us to determine the value of the original number and predict the outcome of Barney's multiplication.

The following best describes the location of lake Eyre as it relates to sea level is -50. Therefore, option D is the correct answer.

Given that, Lake Eyre in Australia is approximately 50 feet below sea level.

Mean sea level is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.

Now, if the surface sea level is 0.

50 feet below sea level = 0-50=-50

The following best describes the location of lake Eyre as it relates to sea level is -50. Therefore, option D is the correct answer.

The total length of string needed to decorate 17 identical decorative bottle is 3570 cm or 35.7 m

Given:

Question

Total length of string needed for 17 identical decorative bottle?

String A = 35

String B = 5 x string A

            = 5 x 35

            = 175 cm

String B = 175 cm

We need to calculate total string needed for 1 decorative bottle

= String A + String B

= 35 cm + 175 cm

= 210 cm

The total length to decorate one bottle is 210 cm

To decorate 17 identical bottles, it would need:

= 210 x 17

= 3570 cm

Here is to solve the multiplication in standard algorithm method:

   21

  17  x
