Answer:

- 4 3/4 degrees Fahrenheit.

Step-by-step explanation

From 3 to 7 pm is 4 hours, so

Temperature at 7 pm =  5 1/4 - 4 * 2 1/2

=  21/4 - 4 * 5/2

= 21/4 - 10

=  21/4 - 40/4

= -19/4

= - 4 3/4 degrees F

A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction
Alex73 [517]

Answer:

<h3>A) </h3>

First were going to put our numbers in perspective.

\frac{7}{4} ÷ \frac{8}{5}

But to find the improper fraction, we have to <em>cross multiply</em> these numbers.

\frac{7}{4} × \frac{8}{5}

<em>7 x 5 = 35.  </em>

<em>4 x 8 = 32.</em>

Now we have our<em> improper fraction </em>is  \frac{35}{32}

<h3>B)  </h3>

To turn our improper fraction into a <em>mixed number</em>, we will use <em>division</em>.

We know that the 32 can only go into 35 <u><em>one</em></u> time.  We also know that the bottom number <em><u>always</u></em> stays the same.  So our equation will look somewhat like this.

1\frac{?}{32}

Now to fine the top number we will have to<em> subtract 35 from 32</em> because we already know that 32 can go into 35 <u><em>one</em></u> time, so <em>35 - 32 = 3</em>.  So are mixed number will look like this.

1\frac{3}{32}

This is our <em>answer!</em>

Find the number of integral solutions of x+y +z = 12, where −3 ≤ x ≤ 4, 2 ≤ y ≤ 11, and<br> z ≥ 3.
SashulF [63]

There are 59 integer solutions

Such questions are best solved by writing cases and calculating the total number of cases. So beginning with

1)  x = -3. The possible combinations are as follows:-

-3 2 13

-3 3 12

-3 4 11

-3 5 10

-3 6 9

-3 7 8

-3 8 7

-3 9 6

-3 10 5

-3 11 4

10 combinations

2) x = -2

-2 2 12

through

-2 11 3

10 combinations

3) x = -1

-1 2 11

through

-1 10 3

9 combinations

4) x = 0

0 2 10

through

0 9 3

8 combinations

as we can see from the pattern at x =1  we get 7 combinations, at x =2  we get 6 combinations, at x=3 we get 5 combinations and at x =4  we get 5 combinations.

Thus total number of combinations 4+5+6+7+8+9+10+10 = 59 integer solution.

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This wou
aniked [119]

Answer:

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k
