Alfred is practicing typing. The first time he tested himself, he could type 23 words per minute. After practicing for a week, he could type 26 words per minute. After two weeks he could type 29 words per minute. Based on this pattern, predict how fast Alfred will be able to type after 4 weeks of practice

Answers

first time 23 words
after week 26 words
after two weeks 29 words
so after 1 week Alfred is faster on 3 words
so after 4 weeks he could type 35 words per minute

There are approximately 2.2 million deaths per year in country A. Express this quantity as deaths per minute

Answers

1 year = 365 days
365 days = 365*24 hours
365*24 hours = 365*24*60 minutes

2.2 million deaths / year
2.2 * 10^6 deaths / (365*24*60) minutes
4.186 deaths / minute

Answer: Approximately 4 deaths per minutes.

Step-by-step explanation:

Since, 1 year = 365 days,

1 day = 24 hours,

1 hour = 60 minutes,

⇒ 1 year = ( 365 × 24 × 60 ) minutes = 525600 minutes,

If the numbers of deaths in one year = 2.2 million = 2200000

⇒ The numbers of deaths in 525600 minutes = 2200000

⇒ The number of deaths in 1 minute = 2200000/525600 = 4.18569254186 ≈ 4

Hence, There are approximately 4 deaths per minutes.

what are the solution(s) to the quadratic equation 50 – x2 = 0? x = ±2 x = ±6 x = ±5 no real solution

Answers

Consider the given quadratic equation $50-x^2=0$

$x^2-50=0$

Comparing the given quadratic equation to the general equation $ax^2+bx+c=0$ , we get a= 1, b=0 and c= -50

So, the solution to the quadratic equation is given by:

$x = (-b \pm √(b^2-4ac))/(2a)$

$x = (-0 \pm √(0^2-4(1)(-50)))/(2)$

$x = (\pm √(200))/(2)$

$x = \pm \sqrt2 (5)$

$x = \pm 5\sqrt2$

So, the solutions to the given quadratic equation are $x = \pm 5\sqrt2$ .

Answer:

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

Start by narrowing the equasions down, add all the numbers together:

1s + 1s + 1s + 1s = 4s

4s = 4s

Both equasions are equivelent to 4s, so the answer would be True.

If you had trouble understanding that, here is another way:

First lets set a control number for s, like 3. then we are going to place the control into the equasion:

1(3) + 1(3) + 1(3) + 1(3)

4(3)

Now solve:

1(3) + 1(3) + 1(3) + 1(3) = 12

4(3) = 12

Both equasions are equivelent to 12, so the answer would be True, they are equivelent.

Simplify fully 4x + 3y -2 + 2x - 8y -6

Answers

Hi, Amyleighx!

First we want to identify any common factors.
4x+3y-2+2x-8y-6
3y-8y=-5y
4x+2x=6x
-2-6=-8
-5y+6x-8

I hope this helps;)

combine like terms. you can combine 4x and 2x, so that is 6x. now combine 3y and-8y and get -5y. combine-2 and -6 and get -8. now put ur terms together. 6x-5y-8
