A plane flies over city A and reaches city B, 115 miles away, in 15 minutes. Find the speed of the plane in miles per hour assuming the plane flew at a constant speed.

A. 300 mph
B. 460 mph
C. 600 mph
D. 680 mph

Answers

Answer 1
So you want to find how many miles are being flown in one hour.

There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.


60 / 15 = 4.

Now multiply 115 by 4,

115 x 4 = 460


Therefore the plane is flying at B. 460 mph.

Hope I helped!

Keith uses 18 cherries and 3 peaches to make a pie filling. Lena uses an equivalent ratio of cherries to peaches when she makes pie filling. Can Lena use a ratio of 21 cherries to 6 peaches?

Answers

No, she cannot use a ratio of 21 to 6. You can figure this out in a few different ways. First you can simplify down the fraction 18/3, to get 6/1. 6/1 does not equal 21/6, because 21/6 equals 7/2. However, 6/1 it does equal 36/6. You could also noticed that three doubles to make six, yet 18 does not double to make 21

Answer:

No, Lena cannot use a ratio of 21 cherries to 6 peaches because it is not equivalent to the equivalent ratio of cherries to peaches.

Step-by-step explanation:

We are given the following in the question:

Keith uses 18 cherries and 3 peaches to make a pie filling

We find the ratio of number of cherries to number of peaches in the pie.

Equivalent Ratio =

[tex]\displaystyle\frac{\text{Number of cherries}}{\text{Number of peaches}} = \frac{18}{3} = \frac{6}{1} = 6:1[/tex]

This ration can be interpreted as:

There are 6 cherries in the pie for every 1 peach in the pie.

We have to check whether  Lena can use a ratio of 21 cherries to 6 peaches.

Lena's ratio of number of cherries to number of peaches in the pie =

[tex]\displaystyle\frac{\text{Number of cherries}}{\text{Number of peaches}} = \frac{21}{6} = \frac{7}{2} = 7:2 \neq 6:1[/tex]

No, Lena cannot use a ratio of 21 cherries to 6 peaches because it is not equivalent to the equivalent ratio of cherries to peaches.

x=27
x is 27

put x into angle B,we have
2(27)-1

thus angleB is 53°

hope it helps c:
In Euclidean geometry (the geometry you're probably familiar with), the interior angles of a triangle always add to 180°.

With that knowledge, we can set up an equation that lets us solve for x based on our given angles by setting their sum equal to 180.

[tex]3x+(2x-1)+46=180\\5x+45=180\\5x=135\\x=27[/tex]

To find ∠B, we simply substitute the x for 27:

So, m∠B = 53°.

How long will it take you to bike 225 miles at a speed of 15 miles per hour?

Answers

15 hours. So maybe call an Uber.

The time taken by the bile to cover 225 miles will be 15 hours.

What is velocity?

Velocity is defined as the ratio of the distance moved by the object at a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.

Given that bike covers a distance of 225 miles with a speed of 15 miles per hour.

The time will be calculated as below:-

Velocity = Distance / Time

15 = 225 / Time

Time = 225 / 15

Time = 15 hours

Therefore, the time taken by the bile to cover 225 miles will be 15 hours.

which of the following cannot be classified as a substance a. table salt b. air c. nitrogen d. gold

Answers

B I think because air is a mixture
Final answer:

Among the options given, air cannot be classified as a substance because it is a mixture of gases with variable composition, unlike table salt, nitrogen, and gold, which have constant compositions and are either elements or compounds.

Explanation:

The question is asking which of the following cannot be classified as a substance: a) table salt, b) air, c) nitrogen, or d) gold. To answer this, we need to understand what a substance is. A substance is a form of matter with a constant chemical composition and characteristic properties. It can be an element or a compound, but not a homogeneous or heterogeneous mixture. Among the options given:

Table salt (sodium chloride) is a compound, thus it is a substance.Nitrogen is an element, making it a substance as well.Gold is also an element, so it is a substance.Air, however, is a mixture of many gases, primarily nitrogen, oxygen, and other trace gases, and therefore cannot be considered a substance since its composition can vary.

Based on these classifications, air is the one that cannot be classified as a substance.

Kiki wants to rent a bounce house for her daughter's party. The cost, y, to rent a bounce house for a number of hours, x, is shown in the table. The initial set-up fee is included in the cost.

Answers

You have to make 2 equations

185 = 2(x) + y
X is the hours and y is the setup fee

315 = 4(x) + y

Now you solve the first
185 = 2x+y
185-y = 2x
(185-y)/2 = x
That means you can plug that value into the second equation where you see the x

315 = 4((185-y)/2) + y
315 = 370-2y + y
315 = 370 - y
-55 = - y
55 = y
So y is 55 (the setup fee)

Back to the original

185 = 2(x) + y
185 = 2(x) + 55
130 = 2x
65 = x

Now test it

575 = 8x + y
575 = 8(65) + 55
575 =  520 + 55
575 = 575

Answer:

The initial setup fee is $55.The hourly rate is $65.

Step-by-step explanation:

First of all, we need to find the equation that models this situation.

Let's find the constant ratio of change using two pair of values from the given table.

[tex]m=\frac{575-185}{8-2}=\frac{390}{6}=65[/tex]

The ratio of change is 65.

In other words, the hourly rate is $65, that is, 65 dollars per hour.

Then, we use the point-slope form to find the equation

[tex]y-y_{1} =m(x-x_{1} )\\y-185=65(x-2)\\y=65x-130+185\\y=65x+55[/tex]

Where [tex]55[/tex] refers to the initial condition.

In other words, the initial setup fee is $55.

Caroline has 4 green cards, 3 red cars, 3 orange cards, and 1 gold card. if she discards the gold card, what percent of her remaining cards are red?

Answers

3 reds in the 10 remaining cards
so that is 30% are red
Final answer:

After discarding the gold card, Caroline has 10 cards left. Since 3 of these are red, the percentage of red cards is 30%.

Explanation:

To find the percent of the remaining cards that are red after Caroline discards the gold card, we must first determine the total number of cards left. Caroline initially has 4 green cards, 3 red cards, 3 orange cards, and 1 gold card, totalling to 11 cards. If she discards the gold card, she is left with 10 cards.

Now, since there are 3 red cards out of the 10 remaining cards, to find the percentage of red cards, we perform the following calculation:

Divide the number of red cards by the total number of remaining cards: 3 red cards / 10 remaining cards = 0.3.Convert the decimal to a percentage by multiplying by 100: 0.3 \(\times\) 100 = 30%.

Therefore, 30% of Caroline's remaining cards are red.

If Trevor sets aside 4 biscuits from each batch for a bake sale and puts the rest in a container. Trevor put 80 biscuits in the container.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that Trevor bakes 8 batches of biscuits, with 14 biscuits in each batch. He sets aside 4 biscuits from each batch for a bake sale and puts the rest in a container.

Total number of biscuits = Number of batches × Biscuit in each batch

Total number of biscuits = 8 × 14

Total number of biscuits = 112

Number of biscuits sets aside,

Total number of biscuits sets aside = Number of batches × Biscuit in each batch

Total number of biscuits sets aside = 4 × 8

Total number of biscuits sets aside = 32

The number of biscuits Trevor put in the container is,

=112 - 32

=80

Thus, if Trevor sets aside 4 biscuits from each batch for a bake sale and puts the rest in a container. Trevor put 80 biscuits in the container.

An equation is

It will take _ hours to reach −1°F.

Answers

Final answer:

To find how many hours it will take to reach -1°F starting from 1:00 p.m., where the temperature changes -4 degrees Fahrenheit per hour, we can set up an equation. The equation is 35 - 4x = -1. Solving for x, we find that it will take 9 hours to reach -1°F.

Explanation:

To find how many hours it will take to reach -1°F starting from 1:00 p.m., where the temperature changes -4 degrees Fahrenheit per hour, we can set up an equation. Let x represent the number of hours it takes.

The initial temperature is 35°F at 1:00 p.m. If the temperature changes -4 degrees per hour, then the equation can be written as: 35 - 4x = -1.

To solve the equation, we can first subtract 35 from both sides to isolate -4x. This gives us: -4x = -36.Next, we can divide both sides of the equation by -4 to solve for x. This gives us: x = -36 / -4 = 9.

So, it will take 9 hours to reach -1°F starting from 1:00 p.m.

Eddie is reading a novel for English lass. He has read 173 out of 480. About what percent of the book he has read ?

Answers

Final answer:

Eddie has read about 36% of the book for his English class, calculated by dividing the number of pages read by the total number of pages and then multiplying by 100.

Explanation:

To determine what percent of the novel Eddie has read for his English class, you would use the formula for calculating percentage: Percentage = (Part / Total) × 100. In this case, the part is the number of pages Eddie has read (173 pages) and the total is the number of pages in the novel (480 pages).

Now, let's calculate the percentage:

Percentage = (173 / 480) × 100

First, divide 173 by 480, which gives approximately 0.3604. Then, multiply this result by 100 to convert it into a percentage.

Percentage = 0.3604 × 100 => 36.04%

Therefore, Eddie has read about 36% of the book for his English class.
