I NEED HELP PLEASE!!!! Given a real world problem, can you find the unit rate?

Yuliya22 [10]

Here is an example:

Josh bought 7 apples for $21.

21/7 is 3, so one apple costs $3. This is the unit rate.

21/7 simplifies to 3/1, that’s another way to think about it. Simplify the fraction until the denominator is 1.

Hope this helps! Tell me if you have any questions!

Examine the system of equations. Do you think the lines will intersect? Explain.

Alchen [17]

Yep they do, because if you plug in y for both equations, you get x=0. To find y, plug in 0 for either equation to get -7. (0,-7) should work for both equations since the intersection point is the point where both equations meet.

A circle with radius of 1 cm sits inside a 3 cm x 4 cm rectangle.

White raven [17]

The area of shaded-region is 8.86 cm^2

Step-by-step explanation:

We can see that there is a circle and a triangle in the given figure

In order too find the area of shaded region, we have to find the area of rectangle and circle first. The area of the shaded region will be obtained by subtracting the area of circle from the area of rectangle.

So,

<u>Area of circle:</u>

Radius = r = 1 cm

So,

$A_c = \pi r^2\\= 3.14 * (1)^2\\= 3.14*1\\= 3.14\ cm^2$

<u>Area of rectangle:</u>

Length of rectangle = l = 4 cm

Width of rectangle = w = 3 cm

So,

$A_r = l*w\\= 4 *3\\=12 cm^2$

Now,

$Area\ of\ shaded-region = A_r - A_c\\= 12 - 3.14\\=8.86\ cm^2$

The area of shaded-region is 8.86 cm^2
