Hi!
We use the pithagorean theorem: height^2 = 152^2 - 132^2 = 5680;
height = $\sqrt{5680} = 75.36cm;$

Each side of a fair, six-sided die has a certain number of dots on it, 1,2,3,4,5, or 6. The die is rolled by a board game player

Norma-Jean [14]

Answer:

B. The experiment is rolling the die.

C. A trial is one rolling of the die.

F. The outcome is the number that is rolled on the die.

Step-by-step explanation:

An experiment is defined as an act or operation for the purpose of discovering something unknown. In this case the player is rolling the die to discover a number, thus the experiment is rolling the die.

A trial is a single performance of a defined experiment, since we already know what the experiment is, a trial is one rolling of the die.

The outcome is the observed result from a trial or experiment, in this case, the outcome is the number that is rolled on the die.

A shirt for $40, jeans for $50 and a watch for $35 are purchased at the mall. If 7% sales tax is charged, what will the total co

Inga [223]

Answer:B: 133.75$

Step-by-step explanation:

35 + 40 + 50= 125$

The total sales tax is 7%

We can put this into decimal form 7/100= 0.07

Because we want to just add 7% of the value back on we can also add 1 to that number

1.07

125 x 1.07 = 133.75

Explain how to rewrite the equation -2x - 6y = 18 in slope-intercept form.

MrMuchimi

Answer:

y = -1/3x -3

Step-by-step explanation:

-2x - 6y = 18

We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept

Add 2x to each side

-2x-6y +2x = 2x+18

-6y = 2x+18

Divide each side by -6

-6y/-6 = 2x/-6 + 18/-6

y = -1/3x -3

This is in slope intercept form with the slope -1/3 and the y intercept -3

School trip has 40 boys and 56 girls. What is the greatest number of groups that can be formed? How many boys and how many girls

Kamila [148]

Answer:

a) 8 groups

b) 5 boys per group and 7 girls per group

Step-by-step explanation:

School trip has 40 boys and 56 girls.

We solve the above question using the Greatest Common Factor Method

We find the factors of 40 and 56

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

Then the greatest common factor is 8.

a) What is the greatest number of groups that can be formed?

The greatest number of groups that can be formed is 8 groups

b)How many boys and how many girls will be in each group?

For boys.

The number of boys in each group is calculated as:

40 boys/8 groups = 5 boys per group

For girls

For 56 boys.

The number of boys in each grouo is calculated as:

56 girls /8 groups = 7 girls per group

A disc jockey has 20 songs to choose from and can only play 8 in the next half hour. how many different playlists are possible?

motikmotik

This problem is a combination problem since it did not indicate that there is a specified order of songs to be played. The type of combination problem is without repetition. Thus the working equation would be n!/r!(n-r)! wherein n is the total number of songs to choose from and r is the number of songs you can choose at a given time. The answer would be 125970.
