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.

If you ever need more help, don't be afraid to reach out! I hope this helps!

What is the slope of the line that passes through the points (2,0) and (1,0)? Write
ICE Princess25 [194]

Answer:

m=0

Step-by-step explanation:

The slope of a line can be found using:

m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }

Let's call (2,0) our "2" coordinate, and (1,0) our "1" coordinate.

Coordinates are written as: (x,y)

Therefore, our x2 is 2 and y2 is 0. Our x1 is 1 and y2 is 0.

Substitute these values into the formula .

m=\frac{0-0}{2-1}

m=\frac{0}{1}

m=0

The slope of the line is 0

What is the actual height of the building shown in the model?
julsineya [31]

Answer:

The actual height is 150ft

Step-by-step explanation:

Given

Width : Height = 2cm : 5cm

Actual\ width = 60ft

Required

Determine the actual height

Substitute 60ft for width in: Width : Height = 2cm : 5cm

60ft:Height =2cm:5cm

Express as fraction

\frac{60ft}{Height} =\frac{2cm}{5cm}

\frac{60ft}{Height} =\frac{2}{5}

Make height the subject

Height = \frac{5}{2} * 60ft

Height = 5 * 30ft

Height = 150ft
