The percentage of increase was 87.027... %

<em><u>Explanation</u></em>

The value of U.S exports to China increased from $1480 million to $2768 million.

Suppose, the percentage of increase is  x\%

So, <u>the amount of increase</u> = x\% of 1480 =1480*\frac{x}{100}=14.8x

Thus, the equation will be......

14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= \frac{1288}{14.8}=87.027....

So, the percentage of increase was 87.027... %

Answer: Definition: Ratio of the size of the map to its subject: Scale ... so scale = 1 cm / 100,000 cm = 1/100,000. - Scale ... STEP 1: - 2 cm represents 5 km

Step-by-step explanation:

STEP 1: - 2 cm represents 5 km - (write in full)

- STEP 2: - 1 cm represents 2.5 km - (divide so left side = 1)

- STEP 3: - 1 cm represents 250,000 cm - (convert to same units)

- STEP 4: - scale is 1 : 250,000 - (express as a representative fraction)

3. At a bargain store, Tanya bought 4 items that each cost the same amount. Tony bought 5 items that each cost the same amount,
FinnZ [79.3K]

We'll do it in cents and convert when we have to.

Tanya paid x per item, a total of 4x.

Tony paid x-125 per item (in cents) for a total of 5(x-125)

4x = 5(x-125)

4x = 5x - 625

x = 625 = $6.25  

Check:

4(625) = 2500

5(625-125)=2500, same, checks

Answer: Tanya paid $6.25 per item, Tony $5.00 per item

Determnine if each table shown below represents a function or not.
Kipish [7]

                                                 Table 1

Input (x)               1            3           5            5              9

Output (y)             7           16          19          20           28

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 1, it is clear that:

  • Each input or x-value of the X set has a unique y-value or output of the Y set.
  • There is no duplicated input (repeated x value).

Therefore, Table 1 represents a function.

                                                Table 2

Input (x)               0.5          7           7            12            15

Output (y)             7           15          10          23           30

 

We already know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 2, it is clear that:

  • There is a duplicated input (repeated x value) i.e. x = 7 appears twice. And we can not have repeated input values.

As the input x = 7 is repeated multiple times, thus, the given table 2 does not represent a function.

Therefore,  Table 2 does not represent a function.
