How should the decimal point in 0.937 change to get the correct answer to 0.937 ÷ 10²?

A. move it 2 place to the right

B . move it 2 places to the left

C .move it 3 places to the right

D .move it 3 places to the left

Answers

Answer:

B.

Step-by-step explanation:

When moving a decimal point 2 places to the right you are multiplying. When moving it to the left you are dividing. In this case we are moving 2 places to the left which the exponent 2 is representing. If you were to move 3 places to the right or left you would need to have a three as your exponent.

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The Space Needle is 605 feet tall. If the model is the actual size of the Space Needle, how tall is the model?
Show all your thinking.

Answers

Answer:

it says if it was the exact same size thats what i understood so it would be 605ft tall

Step-by-step explanation:

Answer:

The model is 6.05 feet tall.

Step-by-step explanation:

Now to the breakdown.

What does it mean to scale? Scaling is used for representation drawing or model is designed to tell the audience(those interested in the design) the ratio to which the design was done in respect to the actual size.

From the above definition we can scale down or scale up. To scale down is to reduce the dimensions of the actual size in our design (possibly in an effort to conserve available space). To scale up is to enlarge the dimensions of the actual size in our design (possible in an effort to show intricate and tiny parts).

Back to question, The actual size of the space needle is 605 feet to design this using the actual size will require a very large amount of resources.  So the scale model is made at a scaled down ratio of 1:100 (in a bid to manage available resources like paper size and others pertaining to the design).

1:100 means that every 1ft in the scale model represents 100ft of the actual model.

So for an Height of 605ft the scale model will have representing height of 605/100 = 6.05ft.

It would be 120.

Look at the first column, 40. It’s basically multiplication and you can just use a calculator.

For example, 40 x 1 = 40,
And if you looks the second column, it’s being multiplied by 2. Which would be 40 x 2, you just have to multiply 3 x 40 which is 120.

Which number line shows 1 to 4 divided into thirds?

Answers

Answer:

Line 1.

Step-by-step explanation:

This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:

1/3      2/3      3/3

This is split into thirds

The required number line that represents the dividend of the three is the fourth line. Option D is correct.

Given that.
To determine the line that has a dividend of 3.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3

Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.
