**Answer 1**

We have to wright 100,000 using exponents. The exponent of number shows how many times you use the number in multiplication.

For example: 64 = 8², because: 64 = 8 · 8or: 64 = 4³, because 64 = 4 · 4 · 4 In this case:100,000 = 10 · 10 · 10 · 10 · 10Therefore:100,000 = 10^5 ( or "10 to the fifth power" )Answer: 10^5.

**Answer 2**

Answer: 10^5

Step-by-step explanation: since 10x 5 equals 100,000

Which exponential function goes through the points (1,8) and (4,64)? A) f(x)=4(2)^x

B) f(x)=2(4)^x

C) f(x)=4(2)^-x

D) f(x)=2(4)-x

### Answers

Plug in (4,64) into each answer choice.

A) 4(2)^x

64=4(2)^4

64 = 4(16)

64 = 64

Answer choice A is correct.

B) f(x) = 2(4)^x

64 = 2(4)^4

64 = 2(256)

64≠ 512

Answer choice B is incorrect.

C) f(x) = 4(2)^{-x}

64 = 4(2)^{-4}

64 = 4(-0.0625)

64≠ 0.25

Answer choice C is incorrect.

D) f(x) = 2(4)^{-x}

64 = 2(4)^{-4}

64 = 2(0.00390625)

64≠0.0078125

Answer choice D is incorrect.

Your answer is B) f(x)=2(4)^x

### Answers

The elevator need to climb 117 feet and it reaches 117 feet in 6.5 seconds only. Now, let’s solve for the unit rate of the elevator. What is it’s speed. => 117 feet is the distance that the elevator needs to climb. => 6.5 seconds is the now. To find the speed let’s follow that formula. S = d/t => 117 feet / 6.5 seconds => 18 feet per seconds Unit rate of the elevator speed = 18 feet/s

Each month for 7 months, Samuel mows 3 lawns. How many more lawns does he need to mow before he has mowed 29 lawns. I think it is 8 more lawns and not 7.

7x3=21; 29-21=8.

stickers are made with the same ratio of width to length. a sticker 2 inches has a length of 4 inches. complete the table

### Answers

Answer:

x (Widht) y (Length)

1 2

2 4

3 6

4 8

5 10

Step-by-step explanation:

We can simplify the ratio 2 : 4 by dividing both terms by the greatest common factor, in this case by 2

2/2=1

4/2=2

So, with this information we can find the length multiply by 2 the width

y(length)=2*x

2=4,3=6,4=8,5=10

inches will be x and length will be y you multiply x by 2 to get y

Minxia counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stays the same, how many more silver card would need to be added so the ratio of green cars to silver cars is 1 to 3?

### Answers

The number of silver cars that need to be added will be 100.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Minxia counted 40 green vehicles and 20 silver vehicles in the parking garage. On the off chance that the quantity of green vehicles remains something similar.

Let 'x' be the number of silver cars that need to be added.

If the ratio of green cars to silver cars is 1: 3. Then the number of silver cars that need to be added will be given as,

40 / (x + 20) = 1 / 3

Simplify the equation, then we have

40 / (x + 20) = 1 / 3

(x + 20) = 40 x 3

x + 20 = 120

x = 100

The number of silver cars that need to be added will be 100.

A cartoon lasts 18 minutes.How many seconds is the cartoon?

### Answers

The Cartoon lasts 1080 seconds.

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A cartoon lasts 18 minutes.

We know, 1 minute = 60 seconds

So, 18 minutes= 60 x 18

= 1080 seconds

Hence, the cartoon lasts 1080 seconds.

Suppose you have a coupon for a 20% discount. You buy a game that costs $38. The sales tax rate is 5.5%. Sales tax applies to the cost after the discount. What is the total cost of the game?

### Answers

$32.072 ≈$32.07

20% of $38 is equal to $7.60

$38 - $7.60 = $30.40

5.5% of $30.40 = 1.672

$30.40 + $1.672 = $32.072
