Step-by-step explanation:

As you walk to your car, you notice that your tire is nearly flat! The initial psi level yesterday was 40 but it is now only 38 today. If this trend continues and the tire keeps losing the same percentage of air, how much should be left at the end of the week rounded to 1 decimal? (7 days later)

Answers

Answer:

Step-by-step explanation:

Given that:

Initial psi yesterday = 40 psi

psi today = 38 psi

If trend continues and tire loses the same percentage of air. How much air will be left in tire at the end of the week

1 week ( 7days)

Total loss after 7 days = (amount lost per day * number of days)

Total psi lost per day= [(40 - 38) = 2

% psi lost = (2/40) * 100

= 5%

Applying the exponential loss functin:

A = I ( 1 - r)^t

t = 7days ; r = 5% = 0.05 ; A = amount left ; I = Initial amount

A = 40(1 - 0.05)^7

A = 40(0.95)^7

A = 40 * 0.69833729609375

A = 27.933

A = 27.9 psi

What is the combined weight of the bee and the pollen? Express your answer in scientific notation.

Answers

Answer:

0.18 g

Step-by-step explanation:

Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]

Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]

The above values can be written in the following ways

[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]

[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]

Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]

The combined weight of the honeybee and the pollen is 0.18 g.

180 minus what = 45

i really need this answer thank you

Answers

Answer: 135

Step-by-step explanation: All you need to do is 180-45=135.

The 180 minus 135 is equal to 45.

To find the value that, when subtracted from 180, gives a result of 45,  set up the following equation:

180 - x = 45

To solve for x,  to isolate it on one side of the equation by subtracting 180 from both sides:

180 - 180 - x = 45 - 180

Simplifying:

-x = -135

Now, to solve for x,  multiply both sides of the equation by -1 to change the sign:

(-1) × (-x) = (-1) × (-135)

x = 135
