O 67,475
O 81.928
O 67.209
O 82.414

Answers

Answer 1

Answer:

The first option

67475

Step-by-step explanation:

Step one:

Given data

The population in Smalltown in 2010 was 45,230

rate= 2%= 0.02

time t= 20 years

Step two:

Let P(t) = population t years after 2010  

              = 45230e^0.02t

 

Population in 2030 = P(20)

                                = 45230e^0.02t(20)

                                  = 45230e^0.4

                                  ≈ 67475

bag of sweets £1.50 per bag, buy 3 get 1 free how many sweets can you buy for £9

Answers

Answer: 8

if you're talking about how many bags of sweets you can BUY, as in without counting the ones you got for free, it's 6. if you're talking how much you GOT, it's 8.

Step-by-step explanation:  you can multiply 1.5 times an unknown number to get nine. the unknown number would be the number of bag of sweets you get without the "buy 3 get 1 free" thing. You can reverse the equation to get 9 divided by 1.5 equals 6.

you can then divide 6 by three, which is 2- meaning you got two free bags of sweets. 6 plus 2 is 8.

Answer:

8 I believe

Step-by-step explanation:

1.50 x 3 = 4.50 so for 4 bags you need 4.50

1.50 x 6 = 9 but you can't forget about the buy 3 get 1 deal

you bought 6 which is two times 3 so would get two free

6+2= 8

Sara says, "If you subtract 14 from my number and multiply the difference by - 3, the result is – 42."
What is Sara's number?
Sara's number is |

Answers

Answer:

Sara's number is 28

Step-by-step explanation:

Let's assign Sara's number the variable x and solve this equation using the information provided.

"If you subtract 14 from my number"

x - 14

"and multiply the difference by - 3"

-3(x - 14)

"the result is – 42."

-3(x - 14) = -42

Now we can solve from here for x.

-3(x - 14) = -42

x - 14 = 14

x = 28

Angle J and angle K are complementary angles. The measure of angle J is 18 less than the measure of angle K. Fine the measure of both angles.

Please and thank you.

Answers

Answer:

Step-by-step explanation:

If J and K are complementary, then J + K = 90. If J is 18 less than K, then:

J = K - 18. Now we have a system. We'll sub in K - 18 for J to the first equation:

K - 18 + K = 90 and

2K - 18 = 90 and

2K = 108 so

K = 54

Now that we know K, we'll sub in to find J:

J + 54 = 90 so

J = 36

There are 15 marbles in a jar: 4 red, 5 green, and 6 yellow. You select one marble and do not replace it. Then, you select another marble. Determine if these events are independent

Answers

That events are independent

The events of picking marbles from the jar is independent

An event is independent if the occurrence of one event does not depend on another event.

For example, if you toss a coin and it lands on its head. You then flip another coin and it lands on its tail. These two events are independent. The face the second coin lands on do not depend on which face the first coin lands on. Also, the face that the first coin lands on does not depend on which face the second coin lands on.

In this question, after the first marble is picked, you do not return the first marble into the jar. Then you pick a second marble. The colour of the second marble does not depend on the colour of the first marble you picked. This means that the events are independent.

We can calculate what did he get, as we know he sold 17 vasess for 3.25 dollars each of them, we can multiply:

17 * 3.25 = $55.25

55.25 - 16.21 = $39.04

solve the literal equation 2y + 5x = 3x +8 for x
help please I'm on a timed test​

Answers

Step-by-step explanation:

Simplifying

5x = 3x + 8

Reorder the terms:

5x = 8 + 3x

Solving

5x = 8 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

5x + -3x = 8 + 3x + -3x

Combine like terms: 5x + -3x = 2x

2x = 8 + 3x + -3x

Combine like terms: 3x + -3x = 0

2x = 8 + 0

2x = 8

Divide each side by '2'.

x = 4

Simplifying

x = 4

Answer:

x = -y + 4

Step-by-step explanation:

2y + 5x = 3x + 8

2x + 2y = 8

2x = −2y + 8

x= −y + 4
