Bonnie filled her car's gas tank. She put in 10 1/2 gallons and paid $15.36. Write the ratio in fractional form and determine the cost of gasoline per gallon

Answers

Answer:

1: 2 and $3.072

Step-by-step explanation:

According to the question, the data provided is as follows

10 half gallons

For this she paid $15.36

Based on the above information,

The ratio in fractional form is

= 1 ÷ 2

= 1 : 2

And, the cost of gasoline per gallon is

Since  half of 10 gallons is 5

And, the amount paid is $15.36

So, the cost of gasoline per gallon is

= $15.36 ÷ 5

= $3.072

Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? How is the answer 20.8?

Answers

Answer:

20.8 cm

Step-by-step explanation:

Perimeter of square = 4a

Dimension of the thumb print = 1 cm by 1cm

Perimeter of the size of the square (thumb print) = 4 × 1

= 4 cm

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence,

32cm - 4cm = 28cm

What is the perimeter of the square after 1.5 seconds?

We set up a proportion

Time / perimeter

= 1.5/x = 2.5/ 28

Cross Multiply

= 2.5x = 1.5 × 28

x = 1.5 × 28/2.5

x = 16.8.

Therefore, the perimeter of the square after 1.5 seconds

= 16.8cm + perimeter of the square before expansion.

=16.8 cm + 4 cm

= 20.8 cm

Answer:

C:  20.8 centimeters

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile. A. How far can the car travel with 15 gallons? With 15 gallons of gas, the car can travel 525 miles. B. How much gas does the car use to go 100 miles? The car will need gallons to travel 100 miles.

Answers

Answer:

 525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon

gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

[tex]distance = \frac{miles}{gallon} (gallons)\\distance = \frac{35 miles}{gallon} (15 gallons) = 525[/tex]

divide 6/13 by 6/12 in fraction form

Answers

when you divide 6/13 by 6/12 you should be getting 12/13

step by step :

take the reciprocal ( flipping the numerator and denominator ) of the second fraction and changing the division sign to multiplication :

it should look like this :

6/13 × 12/6

the next step is to multiply the numerator and denominator

it should look like this :

6 × 12 / 13 × 6 = 72/78

the fraction can be reduced by dividing numerator and denominator by greatest common factor of 72 and 78

here the greatest common factor will be 6

it should look like this :

72 ÷ 6 / 78 ÷ 6

you should get 12 / 13 as an answer

so that's it :)

Determine the interval on which the function is constant

Answers

(-2,2)

Just took the quiz, this is 100% correct.

Please mark brainliest! :)

A constant function is a function having the same value of range for different values of the domain.

The interval on which the given function is constant is x ∈ [ -2, 2 ].

What is a constant function?

A constant function is a function having the same value of range for different values of the domain.

We have,

The graph shows that the function is constant at an interval.

The graph of a constant function is always a straight line.

We see that we have a short straight line on the graph.

The straight line starts from the x = -2 till x = 2 on the x-axis.

The straight line has the constant y = -2 on the y-axis.

The x values are called the domain.

The y value is called the range.

The interval on which the graph is constant is x ∈ [ -2, 2 ].

Thus, the interval on which the given function is constant is x ∈ [ -2, 2 ].

Which domain window settings would be appropriate if you wanted to graph the function below in radians for exactly

Xmin = 0 Xmax = 720
O Xmin = 0 Xmax = 2pi
O Xmin = -180 Xmax = 180
O Xmin = - Xmax = 3pi

Answers

Answer:

Xmin = –π  Xmax = 3π

Step-by-step explanation:

Domain window settings Xmin = 0 & Xmax = 720° would be appropriate if you want to graph the function for exactly two periods.

What is the period of a function?

The distance between the repetition of any function is called the period of the function.

For example, for the cosine function, the distance between the repetition of the function is [tex]2\pi[/tex]. So the period of the cosine function is [tex]2\pi[/tex].

If you want to graph the function for exactly two periods the difference between the first and last element of the domain should be two times the period of the function.

i.e. If the domain is [a, b] the value of [tex]b-a = 4\pi[/tex].

Option(1) b-a =720° [tex]=4\pi[/tex]

Option(2) b-a =[tex]2\pi[/tex] [tex]\neq 4\pi[/tex]

Option(3) b-a =360 [tex]\neq 4\pi[/tex]

Option(4) b-a =[tex]3\pi[/tex][tex]\neq 4\pi[/tex]

So, correct option is option(1) i.e. Xmin = 0 & Xmax = 720°

Hence, domain window settings Xmin = 0 & Xmax = 720° would be appropriate if you want to graph the function for exactly two periods.

Four hundred vouchers were sold for a carwash. Vouchers to wash trucks were $4, while vouchers to wash compact cars were $3. If the total sales were $1350, how many of each type of voucher were sold?

Answers

Answer:

150 vouchers to wash trucks were sold

250 vouchers to wash compact cars were sold

Step-by-step explanation:

Here, we are interested in calculating the number of each type of vouchers sold.

Let the number of vouchers to wash trucks be x while the number of vouchers to wash compact trucks be y.

Firstly, we know that both sums up to be 400.

Mathematically;

x + y = 400 •••••••••(i)

Secondly,

since a voucher to wash trucks sell $4, and we sold a total of x, the amount generated from selling is 4 * x = $4x

Same way for the vouchers to wash compact cars, we have a total of $3 * y = $3y

The sum of both gives $1350, which is the total sales.

Mathematically;

4x + 3y = 1350 ••••••(ii)

So we have two equations to solve simultaneously;

x + y = 400

4x + 3y = 1350

Multiply equation i by 4 , we have;

4x + 4y = 1600

4x + 3y = 1350

Subtract equation ii from i, we have 4y-3y = 1600-1350

y = 250

From equation 1, we know that

x + y = 400

This means that;

x = 400 -y

x = 400 -250

x = 150

Un emprendedor sabe que para vender x de sus productos diariamente el precio de cada uno debe ser 96.800-10x pesos. ¿Cuál es el precio, en pesos, al que debe cobrar sus productos para vender 200 unidades diarias? *

Answers

Responder:

94,800 pesos

Explicación paso a paso:

Dado que:

Para vender x de un producto diariamente, el precio al que debe vender cada uno de sus productos = 96800 - 10x pesos

Por lo tanto, para vender 200 unidades al día, el precio a cobrar será:

Sustituye 200 en lugar de x en la ecuación de precio anterior,

Es decir ;

x = 200

Precio = 96,800 - 10 (200) pesos

Precio = 96,800 - 2000

Precio = 94,800 pesos

De ahí que el precio a cobrar al vender 200 unidades diarias sea de 94.800 pesos.

Nina's grades could be better. She gets about five hours of sleep every weeknight and ten hours per night on weekends. How much sleep should she get to better concentrate on schoolwork? five to six hours every night nine to ten hours every night a total of forty hours a week a minimum of eighty hours a week Save and Exit Next Mark this and return​

Answers

Answer:

The correct option is;

A total of forty hours a week

Step-by-step explanation:

The given information in the question are;

The number of hours of sleep Nina gets during weeknights = five hours

The number of hours of sleep Nina gets per night on weekends = ten hours

The number of days in a week = 5 days

The number of days in a weekend = 2 days

Therefore;

The number of hours of sleep Nina gets per week = 5 days × 5 hours/day + 2 days × 10 hours/day

∴ The number of hours of sleep Nina gets per week = 25 hours + 20 hours = 45 hours

The number of hours of sleep Nina gets per week = 45 hours

To better concentrate on schoolwork, Nina could get a total of forty hours a week of sleep a week to increase the number of hours she spends weekly on her schoolwork by up to 5 hours (45 hours - 40 hours).

Kaia calculates the she spends 75 minutes of a school day in science class. If she spends 500 minutes in school, what percent of her school day does Kaia spend in science class

Answers

Answer:

15%

Step-by-step explanation:

Since a percent is out of 100 we can make 75/500 to have the denominator of 100.

To do that you divide

500/5 = 100

and for the numerator

75/5 = 15

whatever you do to one side you must do to the other that's why I divided both sides by 5. The ending fraction would be 15/100 which is the same as 15%
