A tourist takes a picture with a Moai statue on Easter Island. In the photograph, the Moai statue is approximately 4.54.54, poin

KengaRu [80]

Answer:

The of the tourist is 1.67 meters.

Step-by-step explanation:

Height of statue in photograph = 4.5 inches.

Height of tourist in photograph = 1.25 inches.

$\dfrac{Statue}{Tourist}=\dfrac{4.5}{1.25}$

Actual height of statue = 6.0 meters.

We need to find the the actual height of the tourist in meters.

Let x be the actual height of the tourist in meters.

$\dfrac{Statue}{Tourist}=\dfrac{6.0}{x}$

Ratio of height of statue and tourist are proportional.

$\dfrac{4.5}{1.25}=\dfrac{6.0}{x}$

$3.6=\dfrac{6.0}{x}$

$3.6x=6.0$

$x=\dfrac{6.0}{3.6}$

$x\approx 1.67$

Therefore, the of the tourist is 1.67 meters.

Solve this problem and give the total cost

Jlenok [28]

F(h)= 20 +25h

next plug in the hours but first you need to take the minutes and transfer them to hours

120 minutes = 2 hours

so you plug in 20 + 25(2)

that equals 70

therefor your answers are

f(h)= 20 +25h
and
$70

natima [27]

<em>Complete Question:</em>

<em>Select all of the pieces of information that would tell you x and y have a proportional relationship. </em>

<em>Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving. y=3x </em>

<em>1. After 4 minutes, the turtle has walked 12 feet away from the rock. </em>

<em>2. The turtle walks for a bit, then stops for a minute before walking again. </em>

<em>3. The turtle walks away from the rock at a constant rate. </em>

Answer:

1. After 4 minutes, the turtle has walked 12 feet away from the rock.

3. The turtle walks away from the rock at a constant rate.

Step-by-step explanation:

Given

$y = 3x$

Required

Determine which of the options answers the question

Recall that:

$y = distance$

$x = time$

Analyzing the options 1 after the other:

Option 1:

In this option, we have that:

$y = 12$

$x = 4$

Substitute these values of x and y in the given equation

$y = 3x$

$12 = 3 * 4$

$12 = 12$

Because both sides of the equation are equal, this option shows a proportional relationship

Option 2:

The given equation cannot be used to ascertain the information given in this option.

Because for a every time (in minutes) traveled by the turtle, there's a corresponding distance moved.

Option 3:

Recall that

$y = 3x$

Assume $x = 5$

y would be

$y = 3 * 5$

$y = 15$

Assume $x = 6$

y would be

$y = 3 * 6$

$y = 18$

For every values of x and corresponding y value, there exist a constant relationship because:

$\frac{y}{x} = 3$

This implies that the rate at which the turtle moved is 3ft/s and this rate is constant.

In Littletown, the probability that a baseball team goes to the city playoffs is

tatuchka [14]

Answer:

C. 0.10

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Goes to the city playoffs

Event B: Goes to the state playoffs.

In Littletown, the probability that a baseball team goes to the city playoffs is 0.20.

This means that $P(A) = 0.2$

The probability that the team goes to the state playoffs given that the team goes to the city playoffs is 0.50.

This means that $P(B|A) = 0.5$

What is the probability that a randomly selected team from Littletown goes to the city and state playoffs?

This is $P(A \cap B)$ . So

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(A \cap B) = P(A)*P(B|A) = 0.2*0.5 = 0.1$

The correct answer is given by option C.
