A study show that there are 16 vehicles for every 10 households how many vehicles are there for 107 million households
Lisa [10]
\bf \begin{array}{ccll}
vehicles&households\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
16&10\\
v&107E6
\end{array}\implies \cfrac{16}{v}=\cfrac{10}{17E6}\implies \cfrac{17E6\cdot 16}{10}=v

just to clarify the engineering notation, E6 is just 1 and 6 zeros, or a million, thus, 107,000,000 is just 107E6.

Explain how 6/12 and 4/8 are equal fractions
bogdanovich [222]

6/12 and 4/8 are equal fractions, as, when simplified, they share a simplified fraction.

Note that what you do to the denominator, you do to the numerator. Find common denominators for both fractions:

(4/8)/(2/2) = 2/4

(6/12)/(3/3) = 2/4

As you can tell, when they share a common denominator (4), the numerators are the same as well (3).

An amusement park opens daily at 9:30 a.m. This morning the parking lot for the amusement park opened at 8:00 a.m. At 9:00 a.m.,
Eddi Din [679]

Answer:

An exponential function

Step-by-step explanation:

So let's suppose that at 9:00 am there were 132 cars. We'll call this P_0

P_{0}=132

On the next half an hour, let's say at 9:30, the number of cars trippled, this is:

P_{1}=132*3=396

the next half an hour, at 10:00 am, the number of cars trippled, this is:

P_{2}=132*3*3=1188

and finaly, at 10:30am, the number of cars trippled again, so:

P_{3}=132*3*3*3=3564

We can now see a pattern there which can be simplified as:

P(n)=P_{0}(3)^{n}

or

P(n)=132(3)^{n}

where:

P_{0}=initial number of cars

n=number of half hours after 9:00 a.m

P_{n}= number of cars after n number of half hours.

That function we found there is an exponential function, which represents an initial amount being multiplied by the same number several times.
