The price of gasoline in this week is 1.05g. Option C

Step-by-step explanation:

Given,

The price of a gallon of gasoline = g in last week.

The price of gasoline increased by 5% this week.

To find the price of gasoline this week.

Formula

If an original price of an object a increased by b% the final price will be = a×[tex]\frac{100+b}{100}[/tex]

So,

The price of gasoline in this week = g×1.05 = 1.05g

[ Please note: Here option C and E have same value. So, both are correct].

The expressions represent this week's price, in dollars, of a gallon of gasoline, is 1.05g.

Given that,

Last week the price, in dollars, of a gallon of gasoline was g.

This week the price of gasoline per gallon increased by 5%.

We have to determine,

Which expressions represent this week's price, in dollars, of a gallon of gasoline?

According to the question,

The price of a gallon of gasoline = g in last week.

The price of gasoline increased = 5% = 0.05

The expressions represent this week's price, in dollars, of a gallon of gasoline is,

= Price of gallon last week + Price of gallon increased this week

= g + 0.05g

= (1 + 0.05)g

= 1.05g

Hence, The expressions represent this week's price, in dollars, of a gallon of gasoline, is 1.05g.

Amanda learns 2.5 recipes per week, so over 6 weeks of training, she would be expected to learn 15 appetizer recipes.

To establish the rate of Amanda learning new appetizer recipes, we need to determine the relationship between time (in weeks) and the number of recipes she learned. After 2 weeks of training, she learned 5 recipes, so we can assume that she learns at a rate of 5 recipes per 2 weeks, or 2.5 recipes per week.

Consequently, to estimate how many recipes she will learn after 6 weeks, we multiply the rate by the amount of weeks, which is: 2.5 recipes per week * 6 weeks = 15 recipes. Therefore, Amanda would be expected to learn 15 appetizer recipes after 6 weeks of training.

The average speed of John and Alice are determined first by dividing the total distance by the total time taken. The ratio of the average speeds is 25:45 or in simplified form, 5:9. Therefore, the correct answer to the question is (c) 5:9.

To find the ratio of the average speed of John to Alice, we first need to calculate their average speed individually. The average speed is obtained by dividing the total distance covered by the total time taken.

For John, his average speed would be 150km/6 hours = 25km/h. For Alice, her average speed would be 180km/4 hours = 45km/h.

So, the ratio of the average speed of John to Alice would be 25 : 45. In simplest form, this ratio becomes 5 : 9 (divided both numbers by 5).

Therefore, the answer is (c) 5:9.

Answer:

There are 71 students that are left

Step-by-step explanation:

Let's calculate the number of students left this way:

Total students = 30 * 6 = 180

Students that went to the the slides = 42

Students that went to the the swings = 28

Students that went to the the swings = 39

Students left = Total students - Students that went to the the slides - Students that went to the the swings - Students that went to the the swings

Replacing with the real values, we have:

Students left = 180 - 42 - 28 - 39

Students left = 180 - 109

Students left = 71

Answer:

Step-by-step explanation:

j + p = 178

j = p + 10

p + 10 + p = 178

2p + 10 = 178

2p = 178 - 10

2p = 168

p = 168/2

p = 84 <==== Phil's score

j = p + 10

j = 84 + 10

j = 94 <====Jerry's score

Final answer:

Jerry scored 94 and Phil scored 84.

Explanation:

To find Jerry and Phil's scores, we'll set up two equations based on the given information. Let's say Jerry's score is represented by 'J' and Phil's score is represented by 'P'. We know that Jerry scored 10 points higher than Phil, so J = P + 10. We also know that their scores combined equal 178, so J + P = 178. Now we can solve these two equations to find each student's score. Substituting the first equation into the second equation, we get (P + 10) + P = 178. Simplifying this equation gives us 2P + 10 = 178. Subtracting 10 from both sides gives us 2P = 168. Finally, dividing both sides by 2 gives us P = 84. So Phil's score is 84. Substituting this value back into the first equation, we get J = 84 + 10 which gives us J = 94. Therefore, Jerry's score is 94.

An equation is created to solve for the brother's age: b - 18 = 19. By adding 18 to both sides, we determine the brother is 37 years old.

To solve for the brother's age, you need to create an equation based on the information given. Since the sister is 19 years old, and the brother says his age minus eighteen is equal to the sister's age, the equation is: b - 18 = 19.

Now, solve for b (the brother's age) by adding 18 to both sides of the equation:

Therefore, the brother is 37 years old.

The number of kids attending the circus is 1300.

Let's denote:

- ( K ) as the number of kids attending the circus.

- ( A ) as the number of adults attending the circus.

Given:

- The price of a kid's ticket is $2.50.

- The price of an adult's ticket is $6.

- The total ticket sales is $7,150.

- The number of kids attending the circus is twice the number of adults.

We can set up a system of equations based on the given information:

1. The total ticket sales:

[tex]\[ 2.50K + 6A = 7150 \][/tex]

2. The number of kids attending the circus is twice the number of adults:

[tex]\[ K = 2A \][/tex]

Now, we can solve this system of equations.

We can substitute the expression for ( K ) from equation 2 into equation 1:

[tex]\[ 2.50(2A) + 6A = 7150 \][/tex]

[tex]\[ 5A + 6A = 7150 \][/tex]

[tex]\[ 11A = 7150 \][/tex]

Now, solve for ( A ):

[tex]\[ A = \frac{7150}{11} \][/tex]

[tex]\[ A \approx 650 \][/tex]

So, the number of adults attending the circus is approximately 650.

Now, we can find the number of kids attending the circus using the expression we found for ( A ) in terms of ( K ):

[tex]\[ K = 2A \][/tex]

[tex]\[ K = 2 \times 650 \][/tex]

[tex]\[ K = 1300 \][/tex]

So, the number of kids attending the circus is 1300.

Answer:

George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

George fell asleep a fifth of the way

He awoke up when he still had to travel a quarter of the distance that he had traveled while sleeping

2. For what part of the journey had he been asleep?

George fell asleep a fifth of the way: 1/5 of the total distance traveled and 4/5 of the distance away from his grandma

When he awoke up = 1/4 * 4/5 = 1/5

He had been asleep = 5/5 - 1/5 -1/5 = 3/5

It means George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma

The height of the ball above the ground before it was dropped = 400 ft.

Step-by-step explanation:

Given:

The quadratic function that models the height of the baseball above the ground in feet , [tex]t[/tex] seconds after it was dropped is given as:

[tex]h(t)=-16t^2+400[/tex]

To find [tex]h(0)[/tex] and interpret the meaning of the function value in contect of the problem.

Solution:

In order to find [tex]h(0)[/tex], we will replace [tex]t=0[/tex] in the given function as [tex]h(t)[/tex] is a function of time [tex]t[/tex].

Thus, we have:

[tex]h(0)=-16(0)^2+400[/tex]

[tex]h(0)=16(0)+400[/tex]

[tex]h(0)=0+400[/tex]

[tex]h(0)=400[/tex]  (Answer)

The above function value for [tex]h(0)[/tex] shows that height of the ball before it was dropped i.e. at time = 0 seconds.
