In 1867, the United States purchased Alaska from Russia. Alaska is about 5.9 × 105 square miles. The United States paid about $12.20 per square mile. Approximately how much did the United States pay Russia for Alaska? Complete the steps to answer the question. 1. Write the expression: (5.9 × 105)(12.2) 2. Multiply the decimal values: × 105 3. Write in scientific notation: × The United States paid Russia approximately for Alaska.
Answer:
$7.198 * 10^6
Step-by-step explanation:
Given that :
Total Area of Alaska = 5.9 * 10^5 mi²
Cost of Alaska per square mile = $12.20
Total amount paid to purchase Alaska:
(Total area in square miles * Cost per square mile)
(5.9 × 10^5) * $12.20
(5.9*12.20) * 10^5
71.98 * 10^5 dollars
= $7.198 * 10^6
Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6
Answer:
1. Write the expression: (5.9 × 105)(12.2)
2. Multiply the decimal values:
✔ 71.98
× 105
3. Write in scientific notation:
✔ 7.198

pushing a car 15 m using a force of 500 N. How much work was done?
Answer:
Work = Force × distance = 500 × 15 = 7,500 J.
Hope this helps! Merry Christmas and Happy New Year!
Total work done by pushing the car for a distance of 15 m using a force of 500 N is 7500 Joule.
What is total work done?The total work done can be derived in terms of the products of force applied and the total distance covered.
Therefore,
Total work done = force × distance = 500 × 15 N-m = 7500 Joule
Hence, 7500 Joule work is done.

Tyler paid $16 for 4 raffle tickets.5.
What is the price per ticket?6.
How many tickets is that per dollar?
Answer:
$4/ticket; .25ticket per dollar
Step-by-step explanation:
Tyler paid $16 for 4 raffle tickets.
Part 1: What is the price per ticket?
Part 2: How many tickets per dollar?
For part 1, you will divide $16 by 4 tickets.
16/4=4
You can get 4 tickets for $16 so that's $4/ticket.
For part 2, you already know that it is $4 for one ticket. The question wants to know how many tickets you will get for $1. To find this answer you will divide 1 by 4.
4/1 = .25
So you can get .25 of a ticket per dollar.

A pair of jeans is on sale for 20% off. The sale price is $55.00. What is the original amount of the pair of jeans?
Answer: 275$
I'm not entirely sure I did this right! But at least try!!!
Step-by-step explanation:
20/100 = 55/x (cross multiply)
20x = 5,500 (divide)
X = 275
The original price of the pair of jeans is $ 68.75
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The sale price of the jeans = $ 55.00
The discounted percentage of the pair of jeans = 20 %
Let the original price of the jeans be = A
To calculate the original price of the jeans ,
Original price of the jeans A will be discounted percentage less than and is equal to the sale price of the jeans
So ,
Original price of the jeans A - discounted percentage of the pair of jeans = Sale price of the jeans
And ,
A - ( 20/100 ) A = 55
( ( 100A - 20A ) / 100 )A = 55
(80/100 ) A = 55
( 4/5 ) A = 55
Multiply by 5/4 on both sides , we get
A = ( 55 x 5 ) / 4
A = 275/4
A = $ 68.75
Therefore , Original price of the jeans A = $ 68.75
Hence , the original price of the jeans is $ 68.75

This year, Farah's car is worth $22,000. If the value of Farah's car decreases by 8%, what will her car be worth next year?
Answer:
$20,240
Step-by-step explanation:
Multiply 22,000 by 0.92% since if you subtract 0.08 which is equivalent to 8% from 1, you would need that percentage to get to your final answer which is $20,240.
Another option is to do the same thing except multiply 22,000 by 0.08% in which $1,760 is being cut off as it decreases. Subtract that number from $22,000 to get the same answer mentioned earlier.
Answer:
$20,240
Step-by-step explanation:
This is a simple interest formula.
$22,000*(8%/100%) = $1760
$22,000-$1760 = $20,240

Answer:
ounces
Step-by-step explanation:
moat likely ounces because of the size of the ring
The correct answer from the choices listed above is the first option, ounces.
What is weight?Weight is the measure of the force of gravity acting on a body.
The weight of a gold ring most likely is expressed in ounces. The weight of gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), but its purity, or "fineness" has been measured in a few different ways: "parts fine," "% gold", and carats.

Answer:
There is no variable factor common to 24a and 6
Step-by-step explanation:
First number = 24a

Pime factorisation of 24a = 2×2×3×2×a
Pime factorisation of 6= 3×2
Common factors = 6
Hence, there is no variable factor common to 24a and 6, Other common factor is 6.
