Use two different methods to find an explain the formula for the area of a trapezoid that has parallel sides of length a and B and height H. Consider these ideas or others: combine two copies of a trapezoid to make a parallelogram. Subdivide the trapezoid into two triangles one with base b and one with base a.
The two ways that can be used to find the area of a trapezoid include:
A = (a + b) × h/2A = a × hHow to illustrate the information?It should be noted that a trapezoid simply means a four sided shape that has parallel sides.
To find the area of the shape goes thus:
Find the length of each base.
Find the height of the trapezoid.
Substitute the values into the formula: A = (a + b) × h/2

You buy tomatoes in 25 pound cases. One portion of salad requires .75 ounces of tomatoes. How many portions can be made with one
case?
The amount of the portions can be made with one case will be 399.25 ounces.
What is conversion?Conversion means to convert the same thing into different units.
You buy tomatoes in 25 pounds (11.34 kg) cases.
We know that 1 pound (0.45 kg) is equal to 16 ounces (0.45 kg).
Then the number of the ounces in 25 pounds (11.34 kg) will be
⇒ 25 x 16
Multiply the numbers, then the expression will be
⇒ 400 ounces (11.33 kg)
In 25 pounds of tomatoes, there will be 400 ounces.
One portion of salad requires 0.75 ounces (0.02 kg) of tomatoes.
Then the amount of the portions can be made with one case will be
⇒ 400 – 0.75
⇒ 399.25 ounces
Thus, the amount of the portions can be made with one case will be 399.25 ounces.

How can we write an algebraic expression to describe a two digit number whose unit's digit is 5
ess than the ten's digit?
Let's x be ten's digit
Answer:
required expression = 11x-5
Step-by-step explanation:
We have information about the following things :
Its a two digit numberUnits digit is 5 less than the tens digittens digit is xSince units digit is 5 less than the tens digit, then the unit digit will become
x-5
Now we have these two things:
Tens digit is xUnits digit is x-5Now let us look at some two digit numbers like 29 , 43 and 78
in 29, tens digit is 2 and units digit is 9
29 is formed by multiplying the tens digit by 10 and multiplying the units digit by 1 like this : 29 = (2×10) + (9×1)
Similarly;
43 = (4×10) + (3×1)
78 = (7×10)+(8×1)
Now to get out two digit number from the question, we similarly need to multiply the tens digit with 10 and units digit with 1 and add them like this:
tens digit : x
Units digit : x-5
Hence the number is (x × 10) + [(x-5)×1] = 10x + x-5 = 11x-5
hence the required algebraic expression is 11x-5

Cress purchases parts for use in its manufacturing operation from a variety of different suppliers. One particular supplier provides a part where the assumptions of the EOQ model are realistic. The annual demand is 5,300 units, the ordering cost is $70 per order, and the annual holding cost rate is 25%.
The economic order quantity is 385 and reorder point is 254.
Economic order quantity (EOQ)a. Economic order quantity (EOQ)
EOQ=√2×D×C÷H
Where:
D =Annual Demand
S = Cost of Ordering
H=Holding cost
Hence:
EOQ=√2×5300×70÷.25×20
EOQ=√742,000÷5
EOQ=√148,400
EOQ=385
b. Reorder point
Reorder point=5300/250×12 days
Reorder point=254
c. Reorder point
Reorder point=5300/250×35 days

The difference in the rate of change of both functions is: 15.
What is the Rate of Change of a Function?Rate of change of a linear function = change in y / change in x.
Function A is given as: y = 35x. The rate of change for function A is 35.
From the graph of function B, using two points, (1, 50) and (2, 100):
Rate of change = (100 - 50)/(2 - 1)
Rate of change = 50.

Step-by-step explanation:
cylinder:

first lets find the volume of the cylinder the formula for the volume of a cylinder is pi times radius squared times height. so after plugging in the height and radius you get 689.64242
cone:
radius=5.6 height=6.8
now the volume of the cone, the formula for the volume of a cone is pi times radius squared times height/3. so after plugging in the height and radius of the cone you get 223.31278
