Answer:
Cada garrafa tiene una capacidad de 24 litros.
Step-by-step explanation:
Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.
Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:
(20%/100%)*V
Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:
(30%/100%)*V
El volumen total de agua es la suma de esos dos volúmenes, que nos da:
(20%/100%)*V + (30%/100%)*V
Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:
12 L = (20%/100%)*V + (30%/100%)*V
Ahora podemos resolver esto para V.
12L = 0.2*V + 0.3*V
12L = 0.5*V
12L/0.5 = V
24L = V
Cada garrafa tiene una capacidad de 24 litros.
a. The general form of equation of an uninhibited growth
model is:
A = a e^kt
where A is final amount, a is initial amount, k is
constant and t is time
From Monday to Wednesday, two days have passed so t = 2,
therefore calculating for constant k:
54 = 18 e^k(2)
e^2k = 3
2k = ln 3
k = 0.55
So the function becomes:
A(t) = a e^0.55t
b. Finding for t when A = 2a
2a = a e^0.55 t
0.55 t = ln 2
t = 1.26 days
The first day when he would do these activities on the same day is December 7, 2023.
<h3>When would he do these activities on the same day?</h3>
In order to determine which day Mr. Carson would wash his car, check his oils and check the tire pressure, the multiple of 8, 7, and 9 have to be determined.
A multiple of a number is the product of an integer and that number. A common multiple is a number that is common to all three numbers. The lowest common multiple of 8, 7 and 9 is 504. So, in 504 days he would do all three activities on the same day.
In order to convert 504 days, take note of the following:
365 days = 1 year
12 month = 1 year
1 month = 4 weeks
30 days = 1 month
504 / 365 = 1 year 139 days
139 days / 30 days = 4 months 19 days
504 days = 1 year, 4 months and 19 days
1 year, 4 months and 19 days + July 18, 2022 = December 7, 2023

Point A: 8/10 = 4/5
Point B: 7/10
Point C: 6/10 = 3/5
Point D: 3/10
Answer:
-9x + 52/3
Step-by-step explanation:
(−3x+7)+(−6x+10)+(1/3)
Combine −3x and −6x to get −9x.
−9x+7+10+ 1/3
Add 7 and 10 to get 17.
−9x+17+ 1/3
Convert 17 to fraction 51/3
−9x+ 51/3+1/3
Since 51/3 and 1/3 have the same denominator, add them by adding their numerators.
−9x+
51+1/3
Add 51 and 1 to get 52.
-9x + 52/3
