Answer:


Step-by-step explanation:

This is a super question and it is an excellent exercise for you. When I was teaching, once every term, I would ask my physics class to explain acceleration to a 7 year old. The stats favored the older women (mothers) who took the class. Almost none of the guys could do it. Here's why.

  • The sentences had to be very short. They were barely 6 or 7 words long. They were complete sentences.
  • The examples used had to be very simple. The secret to those mother's answers was they invariably picked something like a stop sign. They all knew that and they always got it right for those reasons.

You are trying to teach a seven or eight year old. Believe it or not, the first thing you have to do is check and see if they know their facts. Can they do 7+8 or 9+ 6 without hesitancy. If they can do those facts do they know the multiplication facts. 4 * 5 etc. They must know those things cold, or you are wasting your time. Don't ask me why. But you can't go on without those 2 fact types solid.

I take it you are trying to do word problems. The best thing you can do is teach them to read.

A man has a dime and a nickel and a penny. How much money does he have? Us a marker to underline the key statement.

a dime,

a nickel

a penny should be underlined. Don't ask for an answer - yet.

======

Keep doing this problem over and over. You are not trying to get an answer. You are trying to get them to understand how to read a question

A person has just less than 4 quarters just less than 5 dimes and just less than 4 nickels. How many coins does he have. That's an important question because the grade three-er is going to have to know what less means.

That should get you started.

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
m_a_m_a [10]

Answer:

523.3 cubic inches

Step-by-step explanation:

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

The shape of a basketball is spherical.

Hence:

The volume of a basketball = 4/3 × π × r³

From the question,

π = 3.14

r = radius = Diameter/2

r = 10 in/2 = 5 in

Hence:

The volume of the basketball

= 4/3 × 3.14 × 5³

= 1570 ÷ 3

= 523.33333333 cubic inches

Therefore, the approximate volume of the basketball = 523.3 cubic inches

A softball has a diameter of 3.82 inches. How many square inches of material is necessary to cover a softball? Use 3.14 for π
lisabon 2012 [21]

Answer:

45.82 square inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, A = 4\pir²

If the diameter is 3.82 inches, the radius is 1.91 inches.

Plug in 3.14 as \pi and 1.91 as r, and solve:

A = 4\pir²

A = 4(3.14)(1.91²)

A = 45.82

So, approximately 45.82 square inches of material are needed.

Y = 6x − 11 −2x − 3y = −7 *
Deffense [45]
6x - 11 - 2x = -7
4x - 11 - = -7
4x = 11
X= 2
12- 11 -4 -3y = -7
-3 -3y = -7
-3y = -4
Y = -1

It should be 2,-1
