The height of glass 1 which in cylindrical in shape is 7.6centimeters. Since the total volume of water added by Celia is 100 cubiccentimeter, and the volume of glass 2 is 26.4 cubic centimeter which is aconical in shape. Subtracting the volume of glass 2 from the total volume glass1 can be calculated and its height.

Answer:

D: 7.6 centimeters

Step-by-step explanation:

If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.

Step 1: Solving for 'b'

We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:

2b / 2 = -3 / 2

b = -3/2

Step 2: Substitute 'b' in the expression 1 - 4b

Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:

1 - 4(-3/2)

Step 3: Simplify the expression

To simplify the expression, we'll perform the multiplication first:

1 + 6/2

Next, we add 1 and 6/2:

1 + 3 = 4

Answer:

Step-by-step explanation:

2b= -3, what is the value of 1 – 4b?

2b= -3

b = -3/2

Then 1 - 4b

= 1- 4(-3/2)

= 1+12/2

= 1+ 6

= 7

Final answer:

The unit rate for Leo's reading is 20 pages per hour and 0.05 hours per page.

Explanation:

To find the unit rate for pages per hour, we need to adjust Leo's reading speed to reflect a full hour rather than half an hour. Since he reads 10 pages in half an hour, then in a full hour, which is twice as long, he would read twice as many pages. So, Leo's rate in terms of pages per hour is 20 pages per hour.

To find the unit rate for hours per page, we flip the ratio. So instead of looking at it as 'pages over hours,' we're looking at it 'hours over pages'. Leo reads 10 pages in half an hour, that is 1 page in 1/20 of an hour (or 0.05 hours). Therefore, his rate in terms of hours per page is 0.05 hours per page.
