It is given that 1 liter of gas cost 26.9 cents.

We have to calculate the cost of 12 gallons of gas.

What will be the cost of 10 pens if 1 pen costs 2 cent ?

The cost of 10 pens will be 10 × 2 = 20 cent.

As per the question ;

Cost of 1 liter of gas = 26.9 cent

∵ 1 gallon = 3.785 liters

So ,

The cost of 1 gallon of gas = 3.785 × 26.9

The cost of 12 gallons of gas will be ;

= 12 × 3.785 × 26.9

=  1221.80 cents

Thus , the cost of 12 gallons of gas will be 1221.80 cents.

Answer:

Tabitha received 60 votes.

Step-by-step explanation:

200 votes × .30 = 60 votes

The given percentage of votes shows that Tyler win the class elections (has the highest percentage of votes - 31%), and Tabitha received 60 votes (30% of 200).

A percentage is a fraction of a whole number represented as a number out of 100.

We are given the percentages of votes received by the candidates in a class election. We are also informed that a total of 200 votes were cast in the elections.

The percentages are as follows:

Tabitha = 30%

Vincent = 12%

Esmeralda = 22%

Nancy = 5%

Tyler = 31%.

We are asked to find the winner of the election and the number of votes Tabitha received.

As Tyler receives the highest percentage of votes (31%), he is the winner of the elections.

Tabitha received 30% of the votes, and the total number of votes = 200

∴ Number of votes Tabitha received = 30% of 200 = (30/100)*200 = 0.3*200 = 6.

∴ Tabitha received a total of 60 votes.

Answer:

20.25

Explanation:

We first need to find the length of one side of the square. We can do this by dividing the area by 4 (27/4), since a square has four sides. You should get 6.75. Now you can multiply 6.75 by three since one side of the square is the same as one side of the triangle. Also, it is an equilateral triangle and all sides are the same. If you multiply correctly, you should get 20.25. Hope this helped!

Answer:

9 sqrt(3)

Step-by-step explanation:

Since the area of the square is 27 cm^2

A = s^2

27 = s^2

Take the square root of each side

sqrt(27) = s

sqrt(9) sqrt(3) = s

3 sqrt(3) =s

We know the the side length of the triangle is s

The perimeter of the triangle is

P =3s = 3 ( 3 sqrt(3))

       = 9 sqrt(3)

Answer:

61

Step-by-step explanation:

Here's a neat trick when you have an odd number of consecutive numbers.

Call the middle number k

Then the smaller number is k-1

The larger number is k + 1

The two ones will cancel.

k-1 + k + k-1 = 180

3k = 180

k = 180/3

k = 60

Therefore the largest number is k + 1 = 60 + 1 =61

Answer:

155

Step-by-step explanation:

17 can go into 26. 1 time then 26-17=9

bring down the 3 and it turns into 93

17 can go into 93 5 times. that equals 85

93-85=8 then add the 5 that make 85

85 divided by 17 =5

so the answer is 155

Answer:

Step-by-step explanation:

To make the problem easier to solve, we will set it up as the equation of the length of time of each class times the number of classes equals the total amount of minutes. However, since we don't know the number of classes, we'll symbolize our two unknowns with two variables.

75x + 45y = 705

(75x + 45y)/15 = 705/15

5x + 3y = 47

y = (47-5x)/3

It looks like we can't simplify the equation any more, so now it is a matter of trial and error. The minimum number of Saturday classes means the maximum number of weekday classes. We first will test for the maximum by assuming there are no Saturday classes, then will work our way up until x is an integer.

If x = 0

(47-5(0))/3 = 47/3 = 15.6666

If x = 1

(47-5(1))/3 = 42/3 = 14

This works. Therefore, the maximum number of weekday classes is 14, or choice b.

Answer:

12/18=2/3

Step-by-step explanation:

You should add up every marbles to find out how many marbles are in total. Then, you should add the green and black marbles. There are 4 black marbles, and 8 green marbles, which results 12 black+green marbles. Then you should make a fraction 12/18, because you are finding the probability of the green+black marbles out of the total marbles. If you simplify, you get 2/3.

The probability of randomly selecting a green or black marble is 12/18.

Probability is the ratio that determines how likely an event is to occur from a set of possible events.

Total number of green marbles = 8

Total number of black marbles = 4

Total number of yellow marbles = 6

Total number of marbles = Total number of green marble + Total number of black marbles + Total number of yellow marbles = 18

P(selecting a green marble) = Total number of green marbles/Total number of marbles

= 8/18

P(selecting a black marble) = Total number of black marbles/Total number of marbles

= 4/18

P(selecting a green or black marble) = (Total number of green marbles + Total number of black marbles)/Total number of marbles

= (8 + 4)/18

= 12/18

Therefore, we have found the probability of randomly selecting a green or black marble to be 12/18.

Answer: 2.5% of people have an IQ over 126.

Step-by-step explanation:

Given: The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13.

126 = 100 + 2(13) = Mean +2 ( standard deviation)

To find : % of people have an IQ over 126.

i.e. % of people have an IQ over Mean +2 ( standard deviation).

According to the standard deviation rule,

95% of data fall within two standard deviations.

Now, 100% - 95% = 5%

and Half of 5% is 2.5%.

So 2.5% of the data lies below 2 standard deviations of mean and 2.5% of the data lies above 2 standard deviations of mean .

i.e.  2.5% of people have an IQ over 126.

B. if the TV is unplugged, then the TV will not turn on.

A conditional statement has two parts: hypothesis (if) and conclusion (then).

The converse is when we switch or interchange our hypothesis and conclusion.

So, we have given statements as:

A. if an ambulance has emergency lights on, then cars on the road pull over.

B. if the TV is unplugged, then the TV will not turn on.

C. if the wind is blowing, then the weather is chilly.

D. if the light bulb was recently on, then the lightbulb is hot.

If we see the converse statement of C.

If the tv does not turn on it’s unplugged.

So the statement is true in both the ways.

c is the amount of chocolate chip cookies

p is the amount of peanut butter cookies

Inequalities help us to compare two unequal expressions. The inequality that represents the number of cookies Mary needs to sell each day is 1.25x + 1y ≥ 25.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Let the number of chocolate chips sold be represented by x, while the number of peanut butter cookies is represented by y.

Given that the selling cost of chocolate chips and peanut butter cookies is $1.25 and $1.00, respectively. Also, Mary needs to make $25 a day, therefore, the inequality can be written in the form as,

1.25x + 1y ≥ 25

Hence, the inequality that represents the number of cookies Mary needs to sell each day is 1.25x + 1y ≥ 25.
