Sam worked on his science fair project for 1/4 hour on Friday and 1/2 hour on Saturday. What are four common denominators for the fractions? Explain your reasoning.

Answers

Answer 1

Answer:

The four common denominators for the condition are 8, 12, 16, and 20.

What are Fractions?

A fraction in mathematics is symbolized by a number that designates a piece of a whole. An object, any number, an amount, or a part of an object can all be considered fractions.

Given Sam worked on his science fair project,

on Friday = 1/4 hour

on Saturday = 1/2 hour

to find the common denominator for both days

multiple of 4 = 4, 8, 12, 16, 20, 24, ......

multiple of 2 = 2, 4, 6, 8, 10, 12, 14, 16, .......

the common term 4 and 2 by the intersection of 4 and 2

[(multiple of 4) ∩ (multiple of 2)] = {4, 8, 12, 16, 20, 24, ......} ∩ {2, 4, 6, 8, 10, 12, 14, 16, .......}

[(multiple of 4) ∩ (multiple of 2)] = {8, 12, 16, 20,...}

Hence the four common multiples of 4 and 2 are 8, 12, 16, and 20.

Find the area of this figure

Answers

Answer:

132 cm squared

Step-by-step explanation:

Find the area of the rectangle on the top first.

Finding the area of a rectangle:

The formula to find the area of a rectangle is to multiply the length by the width. So for your rectangle you would do

7 x 4 = 28cm squared. Keep this is mind and we will move on the the next problem.

The figure under the rectangle is a trapezoid.

To find the area of a trapezoid:

Step 1)

Average the bases.

The dotted line is 7 cm. This is a base.

The line on the very bottom is 19 cm. This is your 2nd base. Find the average of these bases.

(7 + 19) / 2

= 26/2

=13

Step 2)

Multiply this by the height. The height of the trapezoid is 8 cm.

Multiply:

13 x 8

This would get you 104. This is the area of the trapezoid.

Add 104 to the area of the rectangle, 28, to get 132.

The area of the whole figure, therefore, is 132cm squared.

I hope this helps!

What is the equation of the function that is graphed as line b?y = 1/2x - 1
y = 2x + 1
y = 1/2x + 1
y = -4x

Answers

-- Look at the places where the line crosses the 'x' axis and the 'y' axis.
   Between those two points, it goes forward 2 units, but only rises 1 unit.
   So the slope of the line is 1/2 .

-- Look again at the point where the line crosses the y-axis.
   At that point, y=1 .
   That's the "y-intercept".

Now you have the slope and y-intercept of the line.

The equation of ANY straight line is

   y = (slope)x + (y-intercept) .

You know what they both are, so you can easily write

   y = 1/2 x + 1 .

Is that one of the choices ?
Yes it is.
Good enough for me.
That must be the correct one.

With no "blah blah blah" required.

Y=1/2x+1. I need to make it longer so blah blah blah.
