Answer:

1 and 7/12 hours

Step-by-step explanation:

2 and 1/3 is the whole. You need to subtract 3/4. To bring both of these to the same denominator, multiply each fraction by the others denominator. That means 1/3 is now 4/12 and 3/4 is now 9/12. They can now be subtracted. 2 and 4/12 - 9/12 = 1 and 7/12.

Nathan has just bought a new car. He models the value, V, in dollars, of the car after t years as V(t) = 21,000(0.861)t. Based o

Answer:

13.9%

Step-by-step explanation:

The value of car is modeled as:

$V(t)=21,000(0.861)t$

Here we can see that, each year Nathan has considered 0.861 of the previous year value or we can say that Nathan has considered 86.1% of the previous year value. So,

$100-86.1=13.9$

We subtract the percentage value considered from 100 to find out the percentage decrease in the value of the car.

The value of new car is decreasing by 13.9% each year.

vlabodo [156]

Answer:

<h2>The option B and D are the equations.</h2>

Step-by-step explanation:

Let, the total number of students are x.

The number of students having the ticket is $4 + \frac{x}{2}$ .

It is given that the number is 20.

Hence, $4 + \frac{x}{2} = 20\\4 = 20 - \frac{x}{2}$ .

Option B is the equation.

Option D is also the same.

The difference is just, the variable is wriiten in the other side.

If r = 4 and ^a8 = 100, what is the first term of the geometric<br> sequence?

telo118 [61]

The first term of the geometric sequence is 0.0061

<u>Step-by-step explanation:</u>

The general form of geometric sequence is a, ar, ar²,ar³,.......

where,

a is the first term of the sequence.
r is the common ratio. Here, the common ratio r = 4.
The 8th term of the sequence is 100. Hence n = 8.

<u>The formula to find the nth term of the geometric sequence is given by :</u>

⇒ $n_{th} term = ar^{n-1}$

⇒ $8_{th}term = a\times4^{8-1}$

⇒ $100 = a \times 4^{7}$

⇒ $100 = a \times 16384$

⇒ $a = \frac{100}{16384}$

⇒ a = 0.0061

Therefore, the first term of the geometric sequence is 0.0061
