Answer:

1.0014 Miles

Step-by-step explanation:

The light travels at 186,291 miles per second (~300,000 km/s), and speed of sound in dry air is equal to 0.21 - 0.22 miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel one mile and approximately 3 seconds to travel one kilometer. Thanks to this seven orders of magnitude difference in sound and light propagation, we can easily estimate the storm distance

Answer: Mikes home street address number = 52233

Step-by-step explanation:

We need to make a 5 digit number such that

Two digits have values of 50,000 and 200 .

The digits in the ones place is 3 .

Now number is like 50,000 +x + 200 + y + 3  (ten thousand >  thousand > Hundred > tens > ones )

Need values for :  thousands place and tens place

The value of each of the other digits is ten times the value of the digits on its right .

thousands place value (x)= 200 x 10 = 2000

tens place value (y)= 3 x 10 =30

Required number =  50,000 +2000 + 200 + 30+ 3  = 52,233

∴Mikes home street address number = 52233

Answer:

A

Step-by-step explanation:

Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.

The transformation that moves figures to the right 3 units and down 7 units is A. (x, y) ⇒ (x + 3, y - 7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).

A function that moves figures to the right 3 units and down 7 units can be represented by:

(x, y) ⇒ (x + 3, y - 7)

Answer:

C. 5, 12 and 13

D. 6, 8 and 10

Step-by-step explanation:

To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.

A. 3² + 7² ≠ 10²

9 + 49 ≠ 100

58 ≠ 100

B. 4² + 9² ≠ 10²

16 + 81 ≠ 100

97 ≠ 100

C. 5² + 12² = 13²

25 + 144 = 169

169 = 169

D. 6² + 8² = 10²

36 + 64 = 100

100 = 100

Answer:

200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj

Use the format of "if . . . then . . . because . . .” and be sure to answer the lesson question "How is pH used to determine if a solution is acidic or basic?”

Step-by-step explanation:

Answer:

yes it is proportional, if you subtract 3.76 from 5.64 you get 1.88 then add 1.88 to each number to make sure it's right.

Answer:

The statement of whether the cost is proportional to the cost and weight of apples is: yes, it is proportional.

Step-by-step explanation:

From what I can find out from the graph, I would firstly likely want to see if there is a constant between each pound and cost. Meaning, I would want to see if there is a rule that is used throughout the table.

From what I had found out, the rule of this table is:

(x = pounds of apples)

(y = cost of apples)

y = 1.88x

This means that in order to get the 'y' value, also known as the cost of apples, we must multiply 1.88 to the 'x' values, pounds of apples.

This can be found by:

First, dividing 3.76 to 2, your quotient is: 1.88

[tex]\frac{3.76}{2}=1.88[/tex]

Then we need to see if this applies to the other terms as well by multiplying 1.88 to each 'x'

y = 1.88x

y = 1.88(3) = 5.64

y = 1.88(4) = 7.52

y = 1.88(5) = 9.4

You get the same vaule, which means that this is proportional to the table provided.

Answer:

The difference is 3.97 inches of rainfall

Step-by-step explanation:

Here, we want the difference between the wettest and driest months.

From the question, we can see that the wettest month has a rainfall height of 2.3 inches

The driest month has a rainfall of -1.67 inches

So the difference between the two will be;

2.3 - (-1.67)

= 2.3 + 1.67 = 3.97 inches

Answer:

4.03

Step-by-step explanation:

Have to add 2.36 and 1.67 and it would be a positive.

Answer:

r= -3

Step-by-step explanation:

-3 r + 3(r-2) = -2(r+6)

2r=6-12

2r= -6

r= -3

Answer:

(x + y)² = 121

Step-by-step explanation:

Using the identity

(x + y)² - (x - y)² = 4xy , then

(x + y)² - 5² = 4(24) , that is

(x + y)² - 25 = 96 ( add 25 to both sides )

(x + y)² = 121

Answer:

Slope of line = 2

Step-by-step explanation:

Line is passing through the points

[tex] (7,\:5)= (x_1, \:y_1)\\ \:\&\:\\ (12,\:15)=(x_2, \:y_2) [/tex]

[tex]slope \: of \: line = \frac{y_2 - y_1}{x_2 -x_2 } \\ \\ = \frac{15 - 5}{12 - 7} \\ \\ = \frac{10}{5} \\ \\ slope \: of \: line= 2 \\ [/tex]

Next , solve as you would solve any two -step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D

Answer:

The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.

Step-by-step explanation:

When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.

If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
