Answer:
La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.
Step-by-step explanation:
En este enunciado observamos un caso de progresión geométrica, en donde la población de bacterias se duplica cada treinta minutos, es decir:
[tex]\frac{p(n\cdot\Delta t)}{p(0)} = 2^{n}[/tex] (1)
Donde:
[tex]\Delta t[/tex] - Intervalo de tiempo requerido para el incremento geométrico de la población, en minutos.
[tex]n[/tex] - Número de períodos para incremento geométrico, sin unidad.
Sabemos que la población inicial de bacterias es 256 y que 3 horas son 6 veces 30 minutos. Entonces, tenemos la siguiente razón:
[tex]\frac{p(6\cdot \Delta t)}{p(0)} = 2^{6}[/tex] (2)
Si sabemos que [tex]p(0) = 256[/tex], entonces [tex]p(6\cdot \Delta t)[/tex] es:
[tex]p(6\cdot \Delta t) = 2^{6}\cdot p(0)[/tex]
[tex]p(6\cdot \Delta t) = 2^{6}\cdot (256)[/tex]
[tex]p(6\cdot \Delta t) = 2^{6}\cdot 2^{8}[/tex]
[tex]p(6\cdot \Delta t) = 2^{14}[/tex]
La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.

1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answer:
Total cost of footpath = 528 m²
Step-by-step explanation:
Width of footpath is 2m.
Thus,
For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²
For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²
Total area = 112 + 64 = 176 m²
cost to tile foot path is $3 per square metres.
Total cost of footpath = 176 × 3
Total cost of footpath = 528 m²

C. -1
D. -13
I trys but cant get it can i please get help?
Answer:
C. -1
Step-by-step explanation:
Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:
y = mx + b
-7 = -3(2) + b
-7 = -6 + b
-1 = b
So, the y intercept is -1.
The correct answer is C. -1

Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare.
Which equation will represent Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.
12.20h + 7.15 = E
12.20h - 7.15 = E
7.15h + 12.20 = E
7.15h - 12.20 = E
Answer:
B
Step-by-step explanation:
Answer:
E = 12.20(h) - 7.15
h = 6.82 hours
Given:
Pay hour = $12.20 per hour
Bus fare = $7.15
1.Equation:
Assume
She has work for "h" hours
Total earning = E
So,
E = 12.20(h) - 7.15
If,
Total earning = E = $90.45
So,
E = 12.20(h) - 7.15
90.45 = 12.20(h) - 7.15
h = 6.82 hours

In the diagram the sphere touches each face of the cube at one point-the center of each face. if each side of the cube is 7cm, what is a reasonable estimate for the unoccupied volume of the cube?
a: 120cm3
b: 140cm3
c: 160cm3
d: 180cm3
Answer:
C
Step-by-step explanation:
Te unoccupied volume (V) of the cube is calculated as
V = volume of cube - volume of sphere
= 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )
= 343 - [tex]\frac{4}{3}[/tex] π × 3,5³
= 343 - [tex]\frac{4}{3}[/tex] π × 42.875
= 343 - 179.59438
= 163.4....
≈ 160 cm³ ( to the nearest 10 cm³ )
Please help me find the area of the triangles in the picture shown below.
Answer:
1)6
2)20
3)45
Step-by-step explanation:
a=1/2 bh
1) 4*3=12/2=6
2) 8*5=40/2=20
3)15*6=90/2=45
Answer:
1) 6
2) 20
3) 45
Step-by-step explanation:
To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.
