If Sami has 400 marbles, and gives away 2/4 of them about how many does he have left over?

(after you find the answer round it to nearest 100)

Thank you <3

Answers

Answer:

surely it's 200 marbles bc 2/4 is equal to 1/2 and if u then half 400 you get 200

Step-by-step explanation:

Answer:

200 marbles

Step-by-step explanation:

She starts with 400 marbles.

She gives away 2/4 of them

How many does she have left?

How can we simplify this?

Well, 2/4. It makes the problem seem longer and more complicated then it really is. 2/4 is the same as 1/2.

Now what's one half of 400?

200!

You could subtract the 200 from the 400 to officially see how much he has left, but knowing that 200 is half of 400, there will still be 200 left over.

Answers

Answer:

[tex]\frac{2.54cm}{1in}[/tex]

Step-by-step explanation:

Given

[tex]3.6m = 3.6m * \frac{100cm}{1m} * \frac{2.54cm}{1in} * \frac{1ft}{12in} * \frac{1yd}{3ft}[/tex]

Required

Which ratio is incorrect

Each ratio is a conversion of 1 unit to the other.

Taking them one at a time.

The first is [tex]\frac{100cm}{1m}[/tex]

[tex]1m = 100cm[/tex] --- The ratio is correct

The next is: [tex]\frac{2.54cm}{1in}[/tex]

[tex]2.54\ cm = 1\ in[/tex]

The conversion is correct; however the ratio is incorrect.

This is so because, the first ratio ([tex]\frac{100cm}{1m}[/tex]) has centimetre as the numerator

The next should have centimetre has its denominator in order to cancel out the units.

So, the correct ratio is:

[tex]\frac{1\ in}{2.54\ cm}[/tex]

Draw an open circle on 3 and shade to the left.

Step-by-step explanation:

First, solve the inequality.

x - 6 < -3

x - 6 + 6 < -3 + 6

x < 3

The less than symbol (<) indicates that 3 is not part of the solution set. Therefore, the circle will be open.

Since the inequality indicates that x is less than 3, shade to the left of 3.

A student can run 6 miles in 3/4 hour. At this rate, what is the total number of miles the student can run in 1 hour?

Answers

Answer:

The student can run 8 miles in one hour.

Step-by-step explanation:

[tex]\frac{3}{4}[/tex]h = 6 miles

180180 -(98 +46)36

Step-by-step explanation:

The sum of interior angles in a triangle is 180°.

We can write the sum as ...

  A + 98° +46° = 180°

Then solve for A by subtracting the sum (98° +46°) from both sides of the equation:

  A = 180° -(98° +46°)

The result of evaluating that expression is ...

  A = 36°

What is the solution to x - 9 > -15

Answers

Answer:

x > -6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

x - 9 > -15

Step 2: Solve for x

Add 9 to both sides:                    x > -6

Here we see that any number greater than -6 would work as a solution to the inequality.

The solution to the inequality x - 9 > -15 is x > -6.

To solve the inequality x - 9 > -15, we can follow these steps:

Step 1: Add 9 to both sides of the inequality to isolate the variable term:

x - 9 + 9 > -15 + 9

x > -15 + 9

Simplifying:

x > -6

Therefore, the solution to the inequality x - 9 > -15 is x > -6.
