Angel and Jaden were at track practice. The track is 2/5 kilometers around.
​Angel ran 1 lap in 2 minutes.
​Jayden ran 3 laps in 5 minutes
How many minutes does it take Jayden to run 1 kilometer?

Answers

Answer 1

Answer:

See below ↓

Step-by-step explanation:

Information we need

Jayden runs 3 laps in 5 minutes

Solving

Time taken by Jayden to run 2/5 kilometers (1 lap) = 5/3 minutesTime taken to run 1 km = Time taken to run 2/5 km x 5/2 Time taken to run 1 km = 5/3 x 5/2 ⇒ 25/6 minutes (improper fraction form)⇒ 4 1/6 minutes (mixed number form)⇒ 4.17 minutes (decimal form)

-1/4

Step-by-step explanation:

14x - 2x + 3 = 0
12x + 3 = 0
12x = -3
12x/12 = -3/12
x = -1/4

14x - 2x + 3 = 0

To solve for x move the constant to the other side…
14x - 2x = -3

Since 14x - 2x are the same we can subtract them…
12x = -3

Now we divide 12 by both sides, which looks like this…
12x/12 = -3/13
x = -3/12

Gobe weighs 53.6 kg. he wears shoes which weigh 450 gm and carries a school bag weighing 4.5 kg. if he stands on the scales in his shoes and carrying the school bag. what weight will be recorded?​

Answers

Answer:

The key to this question is converting all the mass units to the same unit and adding them all up.

The only value that isn't consistent with the other units is 450 gm or grams.

Recall that 1 gram is equal to 0.001 kilo grams. So if you want to convert grams to kilograms you would multiply that amount by 0.001 or 1/1000

[tex]450gm * \frac{1}{1000} = 0.45kg[/tex]

Now let's add up all the masses.

[tex]53.6kg + 0.45kg + 4.5kg = 58.55 kg\\[/tex]

(Now a few footnotes here, that I considered but wasn't sure about. The answer asks for weight, but you're only given mass to work with. That would be fine, if the question asked you to convert it to SI weight units like Newtons, but there's no mention of that. And also I'm not sure if the question requires significant digits. But I'll continue the answer if you think so)

To convert this into weight in Newtons, multiply by 9.81 m/s^2

[tex]58.55kg*9.81m/s^2 = 574.3755 N\\\\= 5.7 * 10^2 N[/tex]

A. 0.125 foot per square feet

Step-by-step explanation:

When finding average rate of change, use the formula

ΔY/ΔX

The ΔY, or Y final - Y initial would be 1.5-1.0, which is equal to 0.5.

The ΔX, or X final - X initial would be 7-3, which is equal to 4.

Plug these values into the equation ΔY/ΔX to get 0.5/4.

This will give you 0.125.

Since 6 hot dogs are $6.72, 1 hot dog would be that divided by 6, which is $1.12. Now we want the cost of 8 of those hot dogs, so we have to multiply by 8. Hence the answer is $1.12 * 8 = $8.96.

The probability of an event happening is given as 0.45
What is the probability of the event NOT happening?

Answers

Given:

⇒ Probability of happening of an event = 45%

To Find:

⇒ Probability of event

Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.

⇒ Probability of happening event = 45/100

⇒ Probability of happening event = 0.45

⇒ Probability of non happening event = 55/100

⇒ Probability of non happening event = 0.55

Hence, the correct option is (c) 0.45.

b. translation, rotation

Step-by-step explanation:

When a shape is translated, that just means nothing about it has changed except it's location on the coordinate plane. This is that happened with shape 1 - it was translated, and that created shape 2.

When a shape is rotated, that just means it is turned (or rotated) at a specific point. This is what happened to shape 2 that changed it to shape 3.

The other two transformations that aren't shown in this specific example are dilation, which means that the shape either shrinks or grows, and reflection, which means that the shape is reflected across the y-axis or the x-axis.

I included a picture with all four transformation examples in it. I hope this helps! Have a lovely day!! :)

Tracy wants to make a cylindrical model. The height of the cylindrical model, H(V), in inches, is modeled by this

H(V) = 2. 6937

What is the average rate of change of the model's height when its volume changes from 512 cubic inches to

1,000 cubic inches?

The model's height increases by approximately 21. 52 inches for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 022 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 011 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 26. 9 inches for every 1-cubic-inch increase in its volume.

Answers

The average rate of change of the height function is slope of the height function

The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

How to determine the average rate of change?

The height function is given as:

[tex]H(V) = 2.69\sqrt[3]{V}[/tex]

When V = 512, the function becomes

[tex]H(512) = 2.69\sqrt[3]{512}[/tex]

[tex]H(512) = 21.52[/tex]

Similarly;

When V = 1000, the function becomes

[tex]H(1000) = 2.69\sqrt[3]{1000}[/tex]

[tex]H(1000) = 26.9[/tex]

The average rate of change is then calculated as:

[tex]H' = \frac{H(1000) - H(512)}{1000 - 512}[/tex]

This gives

[tex]H' = \frac{26.9 - 21.52}{1000 - 512}[/tex]

[tex]H' = \frac{5.38}{488}[/tex]

Evaluate the quotient

[tex]H' = 0.01102459016[/tex]

Approximate

[tex]H' = 0.011[/tex]

Hence, the model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.
