Bharat types 20 words/min. How many words can he type in each length of time? a) 5 min b) 30 min c) 23 min

e-lub [12.9K]

Bharat can type words in lengths of time as 100 words, 600 words, and 460 words in 5 minutes, 30 minutes, and 23 minutes respectively.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 12×2 = 24

Bharat types 20 words per minute which are given in the question.

To determine the number of words can he type in each length of time

We have to multiply the time by his typing speed.

The number of words that can be typed by Bharat in 5 minutes :

⇒ 20 × 5

⇒ 100

The number of words that can be typed by Bharat in 30 minutes :

⇒ 20 × 30

⇒ 600

The number of words that can be typed by Bharat in 23 minutes :

⇒ 20 × 23

⇒ 460

Therefore, He can type words in lengths of time as 100 words, 600 words, and 460 words in 5 minutes, 30 minutes, and 23 minutes respectively.

If the price of theater tickets increases at 8% per year, about how long will it take to double the price?

Vladimir79 [104]

Answer:

$9\ years$

Step-by-step explanation:

Let

P----> the initial price of the ticket

y ---> the price of the ticket after t years

t---> the time in years

we know that

100%+8%=108%=108/100=1.08

$y=P(1.08)^{t}$ ----> equation A

If the price is doubled

then

$y=2P$ -----> equation B

equate equation A and equation B and solve for t

$2P=P(1.08)^{t}$

Simplify

$2=(1.08)^{t}$

Apply log both sides

$log(2)=t*log(1.08)$

$t=log(2)/log(1.08)=9\ years$

4th term of an arithmetic sequence is 23 and its 11th term is 65, what is its common difference

Rudik [331]

Answer:

d = 6

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₄ = 23 and a₁₁ = 65 , then

a₁ + 3d = 23 → (1)

a₁ + 10d = 65 → (2)

Subtract (1) from (2) term by term to eliminate a₁

10d - 3d = 65 - 23

7d = 42 ( divide both sides by 7 )

d = 6

How to work scientific notation

Feliz [49]

It like instead of saying 0.0000056 you can write it in a shorter form like 5.6 * 10-6.Its like moving the decimal point between 5 and 6 and multiplying it by the power 10*6. its like how much time you move the decimal point, it will be how much time you say 10 to the power of how much you move it.

If the parent function f(x) = x2 is modified to g(x) = 2x2 + 1, which statement is true about g(x)?

satela [25.4K]

F ( x ) = x² ( the parent function )
f ( x ) is an even function.
g ( x ) = 2 x² + 1
g ( - x ) = 2 ( - x )² + 1 = 2 x² + 1
Answer:
A ) It is an even function
