Who's friendships have changed since middle school? How?

Answer:

a)12,17,22,27, 32

b)83,77,71,65,59

Step-by-step explanation:

You go back or forward the amount you went back or forward before

Here's an example with a simple sequence.

2 , 4 , 6 , 8 , ?

The next answer is 10, because it is 2 numbers away from 8, just like 4 is 2 numbers away from 6. In the first one, they are 5 numbers away from each other going up.

In the second one, they are 6 numbers away from each other, going down.

Please tell me if this is the correct answer to the correct question! Thanks!

If it is then here's a challenge :

56, 45, 34, 23, what's next?

Remember to work out how many numbers are between one another!

Good luck!

Answer:

B. Anchorage's temperature > Nome's temperature

Step-by-step explanation:

Answer:

Step-by-step explanation:

Find the sum of the first 42 terms of the following series, to the nearest integer.

2,7,12

Solution

The sum is given by  

SUM_n=n/2*(a_1+a_n)

a_n=a_1+(n-1)d

a_1=2,   n=42,     d=5

The 42nd term is therefore given by  

a_42=2+(42-1)5=207

SUM_42=42/2*(2+207)=21*209=4389

The sum of the first 42 terms of the series, therefore, is 4389

Answer:

Part 1: [tex]P(t)=3(1.4142)^t[/tex]

Part 2: There are 24 people infected

Part 3: P(48)=50,331,648

More than 50 million people are infected after 2 days

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

[tex]P(t)=P_o(1+r)^t[/tex]

Where P(t) is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

We know the Zika virus started with Po=3 people infected. The number of people infected doubles every 2 hours, which means that for t=2 hours, P(2)=6, thus:

[tex]6=3(1+r)^2[/tex]

Dividing by 3:

[tex](1+r)^2=2[/tex]

Solving for 1+r:

[tex]1+r=\sqrt{2}[/tex]

1+r=1.4142

Part 1:

The equation to model the situation is:

[tex]\boxed{P(t)=3(1.4142)^t}[/tex]

Part 2:

After t=6 hours:

[tex]P(6)=3(1.4142)^6[/tex]

P(6)=24

There are 24 people infected

Part 3:

After 2 days, t=2*24 = 48 hours:

[tex]P(48)=3(1.4142)^48[/tex]

P(48)=50,331,648

More than 50 million people are infected after 2 days

Answer:

x = 64

Step-by-step explanation:

To find the value of x, just divide 128 by 2.

It'll get you 64.

To check your answer, just:  2 · 64 = 128

Answer:

64

Step-by-step explanation:

Let's solve your equation step-by-step.

2x=128

Step 1: Divide both sides by 2.

2x/2 = 128/2

x=64

Answer:126 pounds

Step-by-step explanation:

The ratio from dolphins to pound of fish in one day is 1:7

So you have to multiply the ratio on both sides by 18

So you will get 18:126

Answer:

Width=9.5, Length=32.5

Step-by-step explanation:

Let x be the width of the rectangle,

The length is 4 feet more than 3 times the width,

The length= 3x+4

The perimeter is

2(x)+2(3x+4)=84

2x+6x+8=84

8x=76

x=76/8

x=9.5

The Width=9.5

Length= 3(9.5)+4=32.5

Answer:

The maximum revenue Luci Lulu can make selling cookies in one day is $2,000.

The price Luci Lulu should sell the cookies to make the maximum revenue is $1.

Step-by-step explanation:

From the question, we have:

x = −2000p + 4000 ..................... (1)

Where;

x = number of cookies sold

p = price of a cookie, p, and the

Revenue function (R) can therefore be obtained as follows:

R = px ……………………….. (2)

If we substitute equation (1) into (2), we will have:

R = p(−2000p + 4000)

R = −2000p^2 + 4000p ……………… (3)

Differentiating equation (3) with respect to p and set it equal to zero, we have:

−4000p + 4000 = 0

Solving for p, we have:

4000 = 4000p

p = 4000 / 4000

p = 1

Therefore, this implies the price Luci Lulu should sell the cookies to make the maximum revenue is $1.

Substituting p = 1 into equation (3), we have:

R = (−2000 * 1^2) + (4000 * 1)

R = (−2000 * 1) + (4000 * 1)

R = −2000 + 4000

R = 2000

This implies that the maximum revenue Luci Lulu can make selling cookies in one day is $2,000.

3 = 5x - 13 + 3x

3 + 13 = 5x + 3x

16 = 8x

16 ÷ 8 = 8x ÷ 8

2 = x

Answer:

[tex]5x - 13 + 3x = 3 \\ 8x = 3 + 13 \\ 8x = 16 \\ x = \frac{16}{8} \\ x = 2[/tex]

Answer:

x = 45

Step-by-step explanation:

'x' is the hypotenuse or the 'c' in the Pythagorean Theorem (a² + b² = c²)

27² + 36² = c²

729 + 1296 = c²

2025 = c²

√2025 = c

45 = c

Answer:

here!<3

Step-by-step explanation:

A: 9 + 13 + 10 is equal to or less than C

B: 32 is equal to or less than C

Step-by-step explanation:

How I got A:

in order to solve this you have to add 9, 13, and 10.

don't solve it right away, but write every number out individually.

It says in the problem, "Afterward he had AT MOST $10".

With this we know we need a sign other than equal to.

if the amount was at most $10, we need to use equal to or less than.

I chose equal to or less than because it says AT MOST, so the amount he was pain will be equal to, or less than all of then numbers given to us added.

How I got B:

I added 9, 13, and 10.

The sum of these numbers is 32

C is our variable, because we don't know how much they paid him

32 is equal to or less than C

Answer:

B. 86 degrees

Step-by-step explanation:

Given the following angles:

m∠NOQ = 110

m∠NOP = 24

Using the addition postulate:

m∠NOQ =  m∠NOP + m∠POQ

110 = 24 + m∠POQ

m∠POQ = 110 - 24

m∠POQ = 86

Hence the measure of m∠POQ is 86 degrees
