In a sprint to the finish, a professional cyclist travels 380 meters in 20 seconds. At that rate, how many meters will the cyclist travel in 7 seconds?

Answers

Answer:

133m

Step-by-step explanation:

Rate can be defined as the measure of a quantity with time

Rate the professional cyclist travels =380/20

To know the rate rate, in meters will the cyclist travel in 7 seconds then we equate the rate above as

380/20= x/7

Cross multiply

380×7=20X

2660= 20x

X=133m

Hence, the rate rate, in meters will the cyclist travel in 7 seconds is 133m

5. Given that 2x+329, the range of values of x is
(1 Point)​

Answers

Answer:

The range of 2x+329:

[tex]\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Step-by-step explanation:

Given the expression

[tex]2x+329[/tex]

We know that range is termed as the set of values of the dependent variable for which a function is defined.

We also know that the range of polynomials with odd degree is all the real numbers.

       i.e. [tex]-\infty \:<f\left(x\right)<\infty \:[/tex]

The given expression is a polynomial with an odd degree. Hence, the range of this expression will be all the real numbers.

Thus, the range of 2x+329:

[tex]\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

What is the probability of choosing a red M & M on the second try given that the first M & M was red and it was eaten?

Answers

Answer:

Step-by-step explanation:

These both are independent events. Neither is really a conditional probability. It's like asking "What the chances of getting a heads given that you got a tails in the previous through?" The answer is 1/2 if it is a fair coin.

So the total number of M and Ms is

21+ 15 + 10 + 14 + 5 = 65

5/65 * 14/64 = 0.0168  Be careful you you put that in your calculator.

Part B is a bit harder.

14/65 * 13/64 = 0.04375

The fuel tank of a certain airplane can hold up to 300 gallons of fuel. Let Wbe the total weight(in pounds) Let F be the total amount of fuel in this tank ( in gallons) Suppose that W = 6F +4000 gives W as a function of F

Answers

Answer:

Range of weight = [4,000 , 5,800]

Step-by-step explanation:

Given:

Function W = 6F +4000

Full amount of fuel = 300 gallons

No amount of fuel = 0 gallons

Find:

Range of weight

Computation:

Domain : amount of fuel = [0 , 300]

If F = 0

W = 6F + 4,000

W = 6(0) + 4,000

W = 4,000

If F = 300

W = 6F + 4,000

W = 6(300) + 4,000

W = 5,800

Range of weight = [4,000 , 5,800]

Tyler thinks that the relationship between the ages of the children in Family B can be described with 2m – 2y = 10, where m is the age of the middle child and y the age of the youngest. Explain why Tyler is right.

Answers

Answer:

m - y = 5 is equivalent to 2m - 2y = 10

Step-by-step explanation:

Given

m = age of middle child

y = age of youngest child

[SEE ATTACHMENT FOR COMPLETE QUESTION]

Required

Explain why Tyler is correct

From the question, we understand that m is 5 greater than y

This can be represented as

m = 5 + y

To explain why Tyler is correct, we simply solve the above expression.

First, subtract y from both sides

m - y = 5

Multiply both sides by 2

2 * (m - y) = 2 * 5

2m - 2y = 10

This implies that m - y = 5 is equivalent to 2m - 2y = 10

And that means, Tyler conclusion is correct

Answers

Answer: 4.133 kilometers

Step-by-step explanation:

From the question, we are informed that walkway over the hudson, a bridge that crosses the hudson river in poughkeepsie, is 2.063 kilograms long and that Anping bridge, which was built in china 850 years ago, is 2.07 kilograms long.

The total span of both bridges will be the addition of both walkway. This will be:

= 2.063 kilometers + 2.07 kilometers

= 4.133 kilometers
