HELP ME ASAP!!!

Mathematics
1 answer:
Olenka [21]2 years ago
8 0

Answer:

21.6 liters

Step-by-step explanation:

40 drops make up a volume of 10 mL

Therefore, the volume of 1 drop of water = 10mL/40 = 1/4 mL= 0.25mL

Since the tap loses 1 drop of water in 1 sec, it loses 0.25mL of water in 1 second

60 seconds make up 1 second so volume of water lost in 1 minute = 0.25 x 60 = 15 mL

60 minutes make up 1 hour so volume of water lost in 1 hour = 15 x 60 = 900 mL

24 hours make up a day so volume of water lost in 1 day = 900 x 24 = 21,600 mL

Since 1000 mL make up 1 liter, divide by 1000 to get volume in liters

Volume of water lost in 1 day = 21600/1000 = 21.6 liters

Can be done as one equation

V lost in one day = 0.25 x 3600 x 24 mL = 21600 mL = 21.6 L

2. Find the simple interest. P=$90300, R=8.7%, T=2
ZanzabumX [31]

Answer:

$15,712.20

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

8.7%/100 =  0.087

A = P(1 + rt)

A = $90,300(1 + 0.087 * 2)     ( * = multiplication)

I = $106,012.20 - $90,300= $15,712.20

Which you should get $15,712.20

Hope this helps!

-1/4d-2/5d=39 <br> Solve for d <br> Please explain I don’t understand
Maurinko [17]

Answer:

d = -60

Step-by-step explanation:

Given:

-1/4d - 2/5d = 39

-5d-8d/20 = 39

-13/20d = 39

Divide both sides by -13/20

d = 39 ÷ -13/20

= 39 × -20/13

= -60

d = -60

Question is givenin the photo given above​
NNADVOKAT [17]

Step-by-step explanation:

In order to meet at point F, line DF must travel from the top line to the bottom line. If it crosses through E, the midway, that means that it is halfway to the bottom line. This means the distance D E is equal to E F, because both are the distance from midpoint E to one of the sides (top or bottom).

If D E and E F are equal length, then AB and BF must be the length as well, as it is the length DF line takes to get halfway down from the top. Since they are the same length, A F must be twice the length of AB.

Hope this helped!
