The receip calls for 1 3/4 cups of brown sugar. if she makes 2 1/2 batches of cookies, how much brown sugar does she need

1 answer:

8 0

1 and 3/4 cups = 4/4 + 3/4 = 7/4 cups This equals 1 batch. If we want 2.5 batches, then we multiply by 2.5 2.5 x 7/4 = x 4.375 cups = x You can also add the cups one batch and then a half batch at a time. 7/4 + 7/4 + (7/4*1/2) = x multiply the first two (7/4) by 2/2 so there is a common denominator of 8 Then you have 14/8 + 14/8 + 7/8 = 35/8 = 4.375 cups

DanielleElmas [232]

Answer:

The frequency distribution is

S/N Class limit Frequency

1 0-2 4

2 3 -4 1

3 5-6 2

4 7-8 2

5 9 - 10 0

6 11 - 12 0

The value for value upper class boundary of the fifth class is $CB_5 = 10.5$

Step-by-step explanation:

From the question we are told that

The lower class limit is 0

The class width is 2

The scores is 8,6,2,4,2,0,2,6,7

The frequency distribution is

S/N Class limit Frequency

1 0-2 4

2 3 -4 1

3 5-6 2

4 7-8 2

5 9 - 10 0

6 11 - 12 0

Generally the upper class boundary of the fifth class is mathematically represented as

$CB_5 = \frac{10 + 11}{2}$

$CB_5 = 10.5$

200 3. A technician charges $25 per hour plus $50 for a house call to repair home computers. Make a table and a graph to show th

Tju [1.3M]

Recall that for a home visit, the technician charges $50 regardless on the time spent in the repair.

So, to find out the rate, we should calculate the part that depends on the spent time, and the add 50. So for example, we know that the technician spents 1 hour. So, we multiply 1 times 25 and then add 50. So, 25*1 + 50 = 75, which is the rate for a 1-hour repair.

So, in general, if we know that the number of hours is x, we multiply x times 25 and then add 50. Then a table would like this:

x 25*x 25*x +50

1 25 75

2 50 100

3 75 125

4 100 150

Note that as the time increases by one hour, the fare increases by 25. This is an example of a direct variation, since as the independent variable increases (t
