The table shows the record low temperatures for several states. Graph the temperatures on a number line.
OlgaM077 [116]

Step-by-step explanation:

Please find the attachment.

We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.

a recipe calls for 1 and 3/4 cups of flour. How many cups will you need if you are preparing 3 batches of the recipe?
insens350 [35]

The first thing we need to distinguish is what 1 and 3/4 means.  So, 3/4 = .75, so 1 and 3/4 = 1.75


So, we need 1.75 cups of flour for one batch, since you're making three batches, you need three times as much, so

1.75 * 3

5.25 is the answer, to put it back in to fractions,

5 and 1/4 cups of flour are needed.

How is adding and subtracting decimals different from adding and subtracting whole numbers?
Monica [59]
It isn't different, it is very much the same
1-1 = 0
.1-.1 = 0
5.25 - 3.75 = 1.50
1.0005 +1.005 = 2.0055
just make sure to line the decimal places on top of each other <span />

A partial cylinder lies on its side. The bases are a 90° sector of a circle. What is the exact volume of the partial cylinder? C
murzikaleks [220]

The volume of any solid whose base is uniform is V = Ah. Since the base is a sector of a circle, it’s area is defined by the equation A =  θ (r^2)/2, where  θ is in radians.

 90 degrees in radians is Pi/2. So the A = (PI) (r^2)/4

Therefore, V = [(PI) (r^2)/4]*h
