If a fourth plant produces 400 widgets in 60 days, which statement is true?

USPshnik [31]

The complete question in the attached figure

the statements are
1) It makes less than plant B
2) It makes the same as plant A
3) It makes more than plant C

we know that
<span>analyzing the graph

</span>plant A
for x=40 y=100
for x=50 y=200
that means
the production in 10 days is 100 widgets
then
the production in 60 days will be 6*100----> 600 widgets
so
plant A production > plant fourth production
plant fourth production < plant A production

plant B
for x=40 y=0
for x=60 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
so
plant B production < plant fourth production
plant fourth production > plant B production

plant C
for x=20 y=0
for x=40 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
plant C production < plant fourth production
or
plant fourth production > plant C production

therefore

the answer is
3) It makes more than plant C

A TV that usually sells for $175.95 is on sale for 20% off. If sales tax on the TV is 6%, what is the price of the TV, including

shutvik [7]

Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
   = 175.95/5 dollars
       = 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
      = 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
   = 844.56/100 dollars
   = 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
   = 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21

PLS HELP! Will give 25 points!

RSB [31]

Answer and explanation:

Given: Belinda wants to invest $1,000. The table below shows the value of her investment under two different options for three different years:

Number of years 1 2 3

Option 1 (amount in dollars) 1100 1200 1300

Option 2 (amount in dollars) 1100 1210 1331

To find:

Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2?

Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years.

Part C: Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1?

Solution:

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

Part A:

In the case of option 1, the linear function can be used to describe the value of the investment after a fixed number of years. This is because, in option one, the amount increases by a fixed amount every year.

In the case of option 2, the exponential function can be used to describe the value of the investment after a fixed number of years. This is because, in option 2, the amount increase is higher than last year.

Part B:

For option 1, the function is

For option 2, the function is

Here, x is the increase in amount every consecutive year.

Part C:

After 20 years, the amount from option 1 would be 3000 and the amount from option 2 would be 4900. Thus, there is a difference between 1900.

Therefore,

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

Solve the formula A=12bh for h when A=90 and b=15. Write the answer in decimal form.

ohaa [14]

Answer:

Given,

A=90

b=15

A=12bh

Now,

Step-by-step explanation:

Put the given value in the formula

A=12bh

90=12*15*h

90=180h

90/180=h

Hence, h=0.5
