Do the equation

Answers

Answer:

keep reading

Step-by-step explanation:

Well... Dario is at -40 feet. So the difference would be 10 feet.  I don't really know how you would write that equation. But I hope this helped.

The elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.

What is a number line?

A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

Given that Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more. Another diver is diving at -30 feet.

The elevation will be calculated as below:-

Elevation = -30 - ( -40 )

Elevation = -30 + 40

Elevation = 10 feet

Therefore, the elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.

Step-by-step explanation:

A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?

Answers

Answer:

The measure of the new perimeter is 70cm.

Step-by-step explanation:

I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.

The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.

5cm/14cm = 25cm/X

Cross multiply. (The arrows I drew. Multiply diagonally.)

You should get

350 = 5X

We need to get X by itself, so divide both sides by 5.

5X/5 leaves X left

350/5 leaves 70

70 = X

The answer is 70 maybe?

How do you algebraically solve for equilibrium using supply and demand equations?

Answers

Answer:

How do you find the equilibrium price with a supply and demand function?

To determine the equilibrium price, do the following.

Set quantity demanded equal to quantity supplied:

Add 50P to both sides of the equation. You get.

Add 100 to both sides of the equation. You get.

Divide both sides of the equation by 200. You get P equals $2.00 per box. This is the equilibrium price.

It is 80.

Step-by-step explanation:

50% is half and there are 40 blue gumballs in the bag. If you wanted to know the total, you would double 40 because 40 is 50% of the bag, so you are just adding half of it in to get the whole. When you double it, you get 80.
