Answer:

87

Step-by-step explanation:

Let d = number of desktops.

Let a = number of laptops.

a + d = 165

a = d + 9

d = a - 9

a + d = 165

a + a - 9 = 165

2a - 9 = 165

2a = 174

a = 87

Bacteria can multiply at an alarming rate when each bacteria splits into two new cells, thus doubling. If we start with only one
Elan Coil [88]

Answer:

2^24 = 16,777,216 bacterias.

Step-by-step explanation:

So we start with 1 bacteria

after 1 hours: 2*1 = 2

after 2 hours: 2*2 = 2^2 = 4

after 3 hours: 2*2^2 = 2^3  

after n hours: 2^n  

Since one day has 24 hours we have n = 24 and total number of bacteria will

be:  2^24 = 16,777,216 bacterias.

Which amendment prohibits federal and state governments from carrying out these actions?
Anastasy [175]

Answer:

1.The correct answers here are the options A and C.


Under the United States Constitution, the powers that the states possess are those that are not given to federal government and those that are not prohibited by the Constitution itself. This is clearly seen here in the 10th Amendment. The states are free to set forth any laws that are constitutional so this does not mean any powers people want. 


2.The correct answer here is the option A.


John C. Calhoun believed as did some other prominent politicians that nullification of federal laws was justified as the Constitution does not expressly give Congress the right to control states. But nullification is actually not legal and not true because of the Supremacy Clause that states that the Constitution and the federal laws created in accordance with it are the supreme law of the land. Also,  Article III of the Constitution states that it is the federal judiciary that has the final say in the constitutionality of a law.


3.The correct answer here is the option A.


When the citizens of the United States think about  the Constitution they mainly think about the Constitution of the United States. But before the colonies came together to create the Union they already created their own individual constitutions and entered the Union as free states. But these have been changed after the establishment of the Union in order to more reflect the Constitution of the United States.

Is your estimate larger or smaller than the actual number of liters in a gallon? Explain how you know.
SCORPION-xisa [38]

Question:

There are 33.8 fluid ounces in a litre. There are 128 fluid ounces in a gallon. About how many litres are in a gallon?

Is your estimate larger or smaller than the actual number of litres in a gallon? Explain how you know

Answer:

It is larger

Step-by-step explanation:

Given

33.8\ fl\ oz = 1\ litre

128\ fl\ oz = 1\ gallon

Required

Estimate number of litres in a gallon

33.8\ fl\ oz = 1\ litre

128\ fl\ oz = 1\ gallon

Cross Multiply

128\ fl\ oz * 1\ litre = 33.8\ fl\ oz * 1\ gallon

128 * 1\ litre = 33.8* 1\ gallon

Divide both sides by 33.8

\frac{128 * 1\ litre}{33.8} = \frac{33.8* 1\ gallon}{33.8}

\frac{128 * 1\ litre}{33.8} = 1\ gallon

3.78698224852\ litre = 1\ gallon

Approximate

3.787\ litres = 1\ gallon

The estimate is larger than the actual litres to gallon conversion because, in standard units of conversion;

3.785\ litres = 1\ gallon
