Answer:

Jiri's age is 25.

Step-by-step explanation:

Let P = Pamela's age

and J = Jiri's age. Then

                                           (1)        P = J - 12

                                           (2) P + J = 38

Substitute (1) into (2)         J - 12 + J = 38

Add 12 to each side                J + J = 50

Combine like terms                    2J = 50

Divide each side by 2                  J = 25

Jiri's age is 25.

Diane has a rope that is 8 meters long. She cuts away a piece that is 1.67 meters long. How long is the remaining piece of rope?
Readme [11.4K]

Answer:

6.33 m

Step-by-step explanation:

Total length of the rope = 8 m

Cut length of the rope = 1.67 m

We need to find the remaining piece of the rope.

Remaining piece = Total length - cur length

= 8 m - 1.67 m

= 6.33 m

So, 6.33 m is the remaining piece of the rope.

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. Write the express
Wewaii [24]

Answer:

h = V/y^2

Step-by-step explanation:

The volume of a right pyramid is given by the expression = Area of base × height.

Area of base = Area of square at the base

= y × y = y^2.

Now, we substitute these values:

V = y^2 × height

height = V/y^2

Can an answer be incorrect even if it looks reasonable?
Anna [14]

Answer:

  • <em>Yes, an answer can be incorrect even it it looks reasonable.</em>

Explanation:

Yes, an answer can be incorrect even if it looks reasonable, for two main reasons:

  • The assumptions (premises or statements) on which the reasoning is based are wrong.
  • The reasoning sounds good but it is a fallacy.

To avoid the first condition you must be sure about the facts, which may be information from an experiment that you performed or from a source. In order for an answer be correct, make sure your premises are true.

Dealing with the second condition, a fallacy is an argument that seems strictly logical but is misleading: you must learn which reasonings are really valid; this is, that the conclusion unequivocally follows from the premises.

There are rules for the arguments to be valid, and that is the object of logic study.

Fallacies are sometimes used by those interested in supporting a point of view without having true reason on their side. You should have some knowledges about logic to avoid being victim of the fallacies, which can drive you to make wrong decisions.
