A snake slithers 2/9 mile in 4/5 hour.

Answer:

Your answer is A. 8/45 mph

Step-by-step explanation:

I can provide a more detailed answer in a few but for starters, you can rule out answers C & D because that would be the fastest snake alive to be able to travel that far in such a short time.

That leaves a choice between A or B. Using the common denominator method to switch 2/9 and 4/5 to x/45, this makes the most sense. When comparing the 8/45 mph to the actual question, it's very reasonable.

I'll come back in a few and provide the actual math. I'm late for the doctor.

Good luck! Hope this helps!

Answer:

B: 5/18 miles per hour

Step-by-step explanation:

1. multiply the fractions by the reciprocal

2/9 × 4/5 = 10/36

2. Divide answer by common multiple which is 2

10/36 ÷ 2 = 5/18

5/18 miles per hour is the snakes speed

A basketball player has made 70% of his foul shots during the season. If he shoots 3 foul shots in tonight's game, what is the

yulyashka [42]

Answer:

There is a 34.3% probability that he makes all of the shots.

Step-by-step explanation:

For each foul shot that he takes during the game, there are only two possible outcomes. Either he makes it, or he misses. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

$n = 3, p = 0.7$

What is the probability that he makes all of the shots?

This is P(X = 3).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 3) = C_{3,3}.(0.7)^{3}.(0.3)^{0} = 0.343$

There is a 34.3% probability that he makes all of the shots.

GREYUIT [131]

Answer:

Your answer is: Infinitely Many

Any value of x makes the equation true. Also, they are all real numbers.

Step-by-step explanation:

If you are solving to find all Complex Number Solutions: ↓

Solve the equation to find all of the complex solutions and that means that equation will be always true.

¿cual es el perimetro total de un paralelogramo obicuo cuya base mide 2∛54x² cm , y cuyo lado oblicuo mide 3∛54x²?

Step2247 [10]

Answer:

$p=10\sqrt[3]{54}x^2$

Step-by-step explanation:

We are given parallelogram

Since, two opposite sides of any parallelogram are always equal

Let's assume first side =a

second side =b

so, we get

$a=2\sqrt[3]{54}x^2$

$b=3\sqrt[3]{54}x^2$

now, we can find perimeter

perimeter=2a+2b

so, we get

$p=2(2\sqrt[3]{54}x^2)+2(3\sqrt[3]{54}x^2)$

we can simplify it

$p=4\sqrt[3]{54}x^2+6\sqrt[3]{54}x^2$

$p=10\sqrt[3]{54}x^2$ ................Answer
