A boat moves 6 kilometers upstream in the same amount of time it moves 20 kilometers
downstream. If the rate of the current is 6 kilometers per hour, find the rate of the boat in still water.

Answers

Answer 1

Answer:

0.555km p/h

shown as 555m  p/h

Step-by-step explanation:

First we convert km to meters

6k = 6000m

Time = distance / rate.

20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr

then 3.33 / 6 = 0.555 km  = 555 meters p/h

15 is 60% of what number?

Answers

60% of 25 is 15. 100% of 25 is 25, therefore 60 percent of 25 equals 15.

15 is 60% of the number 25

To find the number of which 15 is 60%, we can set up the following equation:

0.60 * x = 15

Here, x represents the unknown number.

To solve for x, we divide both sides of the equation by 0.60:

x = 15 / 0.60

Evaluating the division:

x = 25

Therefore, 15 is 60% of 25.

Answer:

Perimeter of the summer camp = 38 units

Step-by-step explanation:

Distance between P(5, 14) and Q(8, 14) = 8 - 5

                                                                = 3 units

Distance between Q(8, 14) and R(8, 2) = 14 - 2

                                                               = 12 units

Distance between R(8, 2) and S(1, 2) = 8 - 1

                                                            = 7 units

Distance between S(1, 2) and T(1, 8) = 8 - 2

                                                            = 6 units

Distance between T(1, 8) and U(5, 8) = 5- 1

                                                             = 4 units

Distance between U(5, 8) and P(5, 14) = 14 - 8

                                                               = 6 units

Therefore, perimeter of the summer camp = 3 + 12 + 7 + 6 + 4 + 6

                                                                         = 38 units

two fair number cubes are rolled at the same time. what is the probability that both number cubes have the number four facing up? thanksss <3333

Answers

Answer:

The probability that both number cubes have the number 4 facing up is 1/36.

Step-by-step explanation:

For a cube, we have the number:

1,2,3,4,5 and 6

The number 4 only occurs once in the six.

So, the probability of having the number 4 in a single roll is 1/6.

Now, for two rolls, we have two probabilities which we will have to multiply.

Thus, we have the probability as:

[tex] \frac{1}{6} \times \frac{1}{6} = \frac{1}{36} [/tex]

Transform the given function f(x) as described. f ( x ) = x 3 Translate right 2 units Translate up 3 units

Answers

Answer:

Step-by-step explanation:

f(x) = x^3

To get this to move right, you must do the opposite to what you think you should do.

f(x) =(x - 2)^3.  

That looks like it should go left, but it doesn't. It does go right. Suppose you want to know where (0,0) has moved to. If you put x = 2 into x - 2 you get a value of y = 0. That's where the point 0,0 has moved to. It has gone to 2,0

Now you want f(x) to move up 3 units.

f(x) = (x - 2)^3 + 3 The y value lf x = 2 moves up 3 units

Let's see if this is correct.

If you look at the graphs,

The red one is y = x^3The blue one is y = (x - 2)^3The green one is y = (x - 2)^3 + 3

The point 0,0 has been marked for the blue one as it shifts to the right and becomes (2,0) and up 3 in the green graph.

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1527 and a standard deviation of 295. The local college includes a minimum score of 1380 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement

Answers

Answer:

69.15% of students from this school earn scores that satisfy the admission requirement.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 1527 and a standard deviation of 295.

This means that [tex]\mu = 1527, \sigma = 295[/tex]

The local college includes a minimum score of 1380 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?

The proportion is 1 subtracted by the pvalue of Z when X = 1380. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1380 - 1527}{295}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a pvalue of 0.3085

1 - 0.3085 = 0.6915

0.6915*100% = 69.15%

69.15% of students from this school earn scores that satisfy the admission requirement.

Determine the amplitude or period as requested. Period of a y = - 1/3 * sin x - 1/3 pi/3 1/3 d 2pi

Answers

Answer:

[tex]Period = 2\pi[/tex]

Step-by-step explanation:

Given

[tex]y = -\frac{1}{3} * \sin(x - \frac{1}{3})[/tex]

Required

Determine the period

A sine function is represented as:

[tex]y =A \sin(Bx + C) + D[/tex]

Where

[tex]Period = \frac{2\pi}{B}[/tex]

By comparing:

[tex]y =A \sin(Bx + C) + D[/tex] and [tex]y = -\frac{1}{3} * \sin(x - \frac{1}{3})[/tex]

[tex]Bx = x[/tex]

So:

[tex]B = 1[/tex]

So, we have:

[tex]Period = \frac{2\pi}{B}[/tex]

[tex]Period = \frac{2\pi}{1}[/tex]

[tex]Period = 2\pi[/tex]

Hence, the period of the function is [tex]2\pi[/tex]

The exponential model A = 661.7 e^0.011t describes the population, A, of a country in millions, t years after 2003. Use the model to determine the population of the country in 2003

Answers

Answer:

661.7 million

Step-by-step explanation:

Given the exponential model :

A = 661.7 e^0.011t

The general form of an Exponential model is expresses as :

A = A0 * e^rt

Where A = final value ; A0 = Initial value ; r = growth rate and t = time elapsed

From the question t = time after 2003

Therefore, A0 = initial population, which is the population in 2003

Therefore, A0 = 661.7

Or we could put t = 0 in the equation and solve for A

A = 661.7 e^0.011(0)

A = 661.7 * 1

A = 661.7

Hence, population in 2003 is 661.7 million

Find the value of x (this is the angles of a triangle)
(X-13)+x+(×/5+6)=180

Answers

Answer:

72 85 23

Step-by-step explanation:

Equation

(x - 13) + (x/5 + 6) + x = 180                Multiply the equation by 5

Solution

5(x - 13) + 5(x/5 + 6) + 5x = 180*5     Remove the brackets

5x - 65 + x + 30 + 5x = 900              Combine like terms on the left

11x - 35 = 900                                    Add 35 to both sides

      35       35

11x = 935

x = 85

Answer

x - 13 = 85 - 13 =         72

x                      =          85

x/5 + 6 = 17 + 6 =        23

Total =                        180

It might be easier not to multiply through by 5 at the beginning

(x - 13) + (x/5 + 6) + x = 180              Remove the brackets

x - 13 + x/5 + 6 + x = 180                 Combine like terms

2x + x/5 -- 7 = 180

x/5    =   .2x                                     Put 0.2x in for x/5

2.2x - 7= 180                                   Add 7 to both sides

          7      7

2.2x = 187                                       Divide by 2.2

x = 187/2.2

x = 85

Take your pick. Both methods will give the same answer.
