Answer: 9h + 20 = 62

Step-by-step explanation:

he has 20 dollars now he needs 42 more so 9h is how much he earns multiplied by h how many hours he needs to work and you would add 20 onto that for the money he already saved and set that equal to the amount he needs

Answer:

Step-by-step explanation:

1. height serves as the y-value and shoes as the x-value. because domain is the values of x we take in consideration the units x represents. shoe sizes tend to come in sizes 10, 11,12

2. for this one I relied on process of elimination, 2 & 4 include negative numbers and height, at least here, cannot be negative. (3) is representing the y-value or height. so the only one left is 1

this also makes sense because time is positive and the distance would be too.

A video game system and several games are sold for $652. The cost of the games is 3 times as much as the cost of the system. Fin

vesna_86 [32]

Answer:

The cost of the system is $163 and The cost of the games is $489

Step-by-step explanation:

∵ A video game system and several games are sold for $652

∵ The cost of the games is 3 times as much as the cost of the system

→ Assume that the cost of the system is $x

∵ The cost of the system = x

∴ The cost of the games = 3 × x = 3x

∵ The total cost of the system and the games = 652

→ Equate the sum of the cost of the system and the cost of the games

by 652

∴ x + 3x = 652

→ Add the like terms in the left side

∴ 4x = 652

→ Divide both sides by 4 to find x

∵ $\frac{4x}{4}=\frac{652}{4}$

∴ x = 163

∵ The cost of the system = x

∴ The cost of the system is $163

∵ The cost of the games = 3x

∴ The cost of the games = 3(163) = 489

∴ The cost of the games is $489

Help! I need help, pls show work!

Let us first define what any of these terms mean.

The mean is found by adding all the numbers in the set, and dividing the sum by how many numbers are found in the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the sum of the numbers is 5 + 12 + 6 + 3 + 8 + 16 + 8 + 6 = 64. 64 ÷ 2 = 32. Thus, the mean is 32.

The median is found by finding the number in the middle of the set, and dividing it by 2. This is easy in odd numbers as there is only one number in the middle that is the same amount of numbers left and right proportionally. However, in even numbers, there are two middles to be proportional. If it as an even number, then add the 2 middles together, and divide by 2.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, this set has an even number of numbers in the set. Thus, the middles are 3 and 8. 3 + 8 = 11, and 11 ÷ 2 = 5.5. Thus, the median is 5.5.

The mode is the number that most frequently appears in the set. In this case, we have 2 frequent numbers. That is 6 and 8. They both appear 2 times separately. Thus, 6 and 8 are the modes of this set.

The range is the difference (i.e subtraction) between the largest number on the set and the smallest number on the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the range is 16-3 or 13. Thus, the range is 13.

Now that we have the definitions, we can compute the other set very easily.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mean is 18.

> Given set {2, 7, 4, 11, 12, 4, 6}, the median is 5.5.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mode is 4.

> Given set {2, 7, 4, 11, 12, 4, 6}, the range is 10.

Hope it helped!

Triangle ABC is a right triangle. The sides measure AB = 6 and BC = 8. Use the

marin [14]

Answer:

AC = 10 units

Step-by-step explanation:

From the picture attached,

Triangle ABC is a right triangle.

Opposite side of the right angle B = Hypotenuse (AC)

and the other two legs are AB and BC

Pythagoras Theorem states

(hypotenuse)² = (leg 1)² + (leg 2)²

AC² = AB² + BC²

AC² = (6)² + (8)²

AC² = 36 + 64

AC² = 100

AC = √100

AC = 10

Therefore, length of the hypotenuse (AC) = 10 units will be the answer.
