Answer: 7 hours and 8 minutes

Step-by-step explanation:

7 tests in 25 minutes

7 divided by 25= 3.57

3.57 minutes per test times 120 tests= 428.57 minutes

428.57 divided by 60 (60 minutes in an hr) = 7 hours and 8 minutes (and 57 seconds if u want to count those too)

A large department store is prepared to buy 3,800 of your tie-dye shower curtains per month for $5 each, but only 3,600 shower c
Ksivusya [100]

Answer:

q= -40p+c

q= -40p+4,000

Step-by-step explanation:

$5 each for 3800 tye-dye shower curtains

$10 each for 3600 tye-dye shower curtains

Slope of the demand line is

3800-3600/5-10

=200/-5

= -40

Demand function is

q= -40p + c

Where c is a constant

For q=3800 and p=$5

Demand function is

q= -40p + c

3800= -40(5)+c

3800= -200+c

c=3800+200

c=4,000

Linear demand function is

q= -40p+4,000

Show work<br> Find the volume of the pyramid
Burka [1]
<u></u><em>Hello there, and thank you for posting your question here on brainly.

______________________________________________________________
Answer: 128
</em>
<em>Why?
</em><em>______________________________________________________________
To find the volume of a cylinder, we have to use the formula lwh/3. The length is 8, width is 4, and height is 12. So we have to multiply all of those together, then divide by 3. (8 * 4 = 32) -> (32 * 12 = 384) -> (384/3 = 128) The volume is 128.

<em>Hope this helped you! ♥</em><em>

A steel worker dropped his wrench off the top of a new high rise building. How far will the wrench fall in 3 seconds?

Using  S = ut + 1/2gt²,   from rest, u = 0

S = 1/2gt²,               g ≈ 9.8 m/s²

S = <span>1/2 *9.8*3²

</span>S = 0.5<span> *9.8*3*3 
</span>
<span>S ≈ 44.1 m</span>
