Hailey's plane climbed 4,500 feet in 90 seconds. How fast did her plane climb every second?

Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.

This means that [tex]d = 200, t = 19.19[/tex]

So his average speed was of:

[tex]v = \frac{d}{t} = \frac{200}{19.19} = 10.42[/tex]

His average speed was of 10.42 m/s

Answer:

[tex]2\sqrt{2}[/tex]

Step-by-step explanation:

h(10) = 2(10) - 8

        = 12

g(h(10)) = [tex]\sqrt{(12)-4}[/tex]

            = [tex]\sqrt{8}[/tex]

            = [tex]2\sqrt{2}[/tex]

Answer and Step-by-step explanation:

(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.

(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

Multiply

Divide

Add

Subtract

So, the first thing would be to solve any parenthesis.

Secondly, you would evaluate the exponent.

Answer:

-7 / 10

Step-by-step explanation:

use the slope formula

slope= (y2 - y1) / (x2- x1)

which for our case is:

slope= (-5 - 2) / (4- - 6) = - 7/10

Answer:

x = 8

Step-by-step explanation:

-1/4 (2x + 8) = -6​

Multiply both sides by -4.

2x + 8 = 24

Subtract 8 from both sides.

2x = 16

Divide both sides by 2.

x = 8

Answer:

x = 20

Step-by-step explanation:

First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:

2x + 8 + 6x + 12 = 180

Next, we can combine like terms to simplify the equation:

8x + 20 = 180

Now, we can subtract 20 from each side:

8x = 160

Finally, we divide both sides by 8 to find the value of "x":

x = 20

Answer:

standard error of the mean (S.E) = 0.06

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 500

Given variance of the Population = 900

The standard deviation of the Population = √900 = 30

The standard error of the mean is determined by

[tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06[/tex]

Answer:

11.75%

Step-by-step explanation:

The formula for Simple Interest is given as:

I = PRT

Where in the question

I = Interest = $,1762.5

P = Principal = $5,000

T = Time= 3 years

R = Simple Interest rate ??

To solve for R, the formula is given as:

R = I/PT

R = $1,762.5/5,000 × 3

R = 0.1175

Converting to percentage

= 0.1175 × 100

= 11.75%

Answer:

Step-by-step explanation:

The four sides of a square are equal.

7x + 3 = 5x + 8             Subtract 5x from both sides

7x - 5x + 3 = 8              Combine the left

2x + 3 = 8                     Subtract 3 from both sides

2x = 8-3                        Combine the right

2x = 5                           Divide by 2

x = 5/2

x = 2.5

That is not quite the answer

Side = 7x + 3

Side = 7*2.5 + 3

Side = 17.5 + 3

Side = 20.5
