What is the value of the slope of the graph of distance versus time, and what does the slope represent?

Answers

Answer 1
Answer: To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.

An oil refinery produces gasoline from crude oil. For every 10,000 barrels of crude oil supplied, the refinery can produce 6,500 barrels of gasoline. How many barrels of gasoline can be produced from 3,500 barrels of crude oil?

Answers

2,275 barrels of refined oil will be produced from 3,500 barrels of crude oil.


with the information that from 10,000 barrels of crude oil, 6,500 barrels of refined oil are produced, it immediately pops out that from x amount of crude oil, 65% will be refined.

now we need to find what is 65% of 3,500

(65)/(100) = (x)/(3,500)
to find x, we multiply 65 × 3,500 and that amounts to 227,500
that then is divided by 100 so 227,500 ÷ 100 = 2,275

10000 barrels of crude oil produces 6500 barrels gasoline 
1 barrel of crude oil will produce 6500÷10000 barrels of gasoline 
3500 barrels of crude oil will produce 6500 × 3500 ÷10000 barrels 
= 3500 barrels of crude oil produce 2275 barrels of gasoline

Write a word problem that you can solve using multiples to estimate the quotient. Include a solution.

Answer:

Word problem based that can be solved using multiples to estimate the quotient:

Melissa made 326 cupcakes. She packed four cupcakes into each box. How many boxes of cupcakes did she pack? How many cupcakes were left unpacked?


Answer:

Let us consider,

The problem: 'Find two numbers between which the quotient of 50 ÷ 7 lies'.

Solution: We will solve this in two steps.

Step 1: Form a table of multiples of 7.

Counting number               Multiple of 7

           1                                       7

           2                                     14

           3                                     21

           4                                     28

           5                                     35

           6                                     42

           7                                     49

            8                                    56

Step 2: Use the table to find the multiples closest to 50.

Since, 49 = 7 × 7 and 56 = 7 × 8

Thus, 50 lies between 49 and 56.

Then, the quotient is either 7 or 8.

As 50 is closest to 49.

Hence, the quotient of 50 ÷ 7 is 7.

Find the value of 4x^2– 2y when x = 3 and y = 2.

Answers

Answer:

The answer is 32.

Step-by-step explanation:

Remember that order of operation is very important in this problem.

Substitute x for 3 and y for 2 in the equation.

When solving the first term, we must note that we have to square the 3 first before we multiply it by 4. So, 4(3)^2 is basically 36. To simplify the second term you just have to do 2*2, which is 4. 36-4=32, which is the answer.
