How to find hyptenuse of a triangle?

Answers

IF the triangle has a 90-degree angle in it (it's a right triangle), then the length
of the hypotenuse is:

Square root of (square of the shortest side + square of the medium side).

If the triangle is not a right triangle, then it doesn't have a hypotenuse.

A new car sells for $29,250. It straight line depreciates in 13 years. What is the slope of the straight line depreciation equation?

Answers

Answer:

The slope of the straight line is -2,250

Step-by-step explanation:

Given:

The cost of a new car = $29,250

It depreciates in 13 years, it means the value of the zero in 13 years.

Therefore, the value of the car decreasing which is negative.

Let's take "x" is the amount decreasing by years, which represents the slope.

29250 = -13x

Dividing by -13 both sides, we get

-13/-13 x = 29250/-13

x = -2,250

Therefore, slope of the straight line is -2,250

Hope this will helpful.

Which answer describes the restrictions for the variables x+1/x-4?

Answers

The restriction for this is that x ≠ 4. This is because 4 - 4 = 0, and you cannot divide by zero.

An alternative way of writing this (interval notation) is (-∞, 4)U(4, ∞).

pizza perfection sold 93 pizzas on Monday, 67 pizzas on Tuesday, 78 pizzas on Wednesday, 44 pizzas on Thursdays, and 123 pizzas on Friday. on average how many pizzas did they sell per day?

Answers

Answer:

On average 81 pizzas they sold per day.

Step-by-step explanation:

Pizza perfection sold pizzas on each days as :

Monday = 93 pizzas

Tuesday = 67 pizzas

Wednesday = 78 pizzas

Thursday = 44 pizzas

Friday = 123 pizzas

To calculate average pizza sold per day we divide total pizzas to number of days.

Total pizza = 93 + 67 + 78 + 44 + 123 =   405 pizza

Therefore  405 ÷ 5 = 81 pizza

On average 81 pizzas they sold per day.
81 average. Average also known as mean means add them all up the divide by the amount of #s

What is the answer!!

Answers

Answer:

∠ G = 121°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

x + 3x + 25 + x - 5 = 180 , that is

5x + 20 = 180 ( subtract 20 from both sides )

5x = 160 ( divide both sides by 5 )

x = 32

Thus

∠ G = 3x + 25 = 3(32) + 25 = 96 + 25 = 121°

Answer:

121
