Answer:
h = 2.7 m
Step-by-step explanation:
ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal
DE / BC = AD / AB, that is
h / 0.9 = 18 / 6 ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7
Answer:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria in the dish is 500,000
Step-by-step explanation:
Given the information on the table
We are to follow the pattern to determine how many million bacteria were in the dish at 1 p.m. and 12 p.m.
Now:
It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:
Therefore:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria is 0.5 million=0.5 X 1,000,000=500,000

Step-by-step explanation:
Given equation of the horizontal ellipse:
Standard form:
Values of a and b:
Therefore, the radius of the bigger circle is a=r=8 (half the length of the major axis) and the radius of the smaller circle is b=r=4 (half the length of the minor axis).
Given the equation for a circle is , then:
The equation for the larger circle is
The equation for the smaller circle is
Answer:
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
Step-by-step explanation:
Recordamos que la densidad de un material uniforme (), medido en kilogramos por metro cúbico, está definido por:
(1)
Donde:
- Masa, medido en kilogramos.
- Volumen, medido en metros cúbicos.
Ahora calculamos la densidad de cada recipiente:
Recipiente A (, )
El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.
Recipiente B (, )
El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
Answer:
2 kg
As we know that 1 kg = 1000g
so 2000g = 2 kg
