(2.5 x 104). Express your answer in scientific notation.
Answer:
=10.6x104
Step-by-step explanation:
=8.1x104+2.5x104
=(8.1x104+2.5x104)
=10.6x104
(8.1 x104)+(2.5 x 104)
Multiply the numbers
842.4 + (2.5 x 104)
Multiply the numbers

Multiply the digits
4 x 5 =20
Take the last digit and write it in the answer line
Carry the next digit and save it for the next calculation
Multiply the digits
4 x 2=8
Add the carried digit for the previous result
8+2 =10
Write the result in the answer line
Move the next digit and write it the next result below
Every digit multiplied by zero equals zero
Move to the next digit an write the next result below
Every digit multiplied by one stays the same
Add the numbers
Move the decimal sign as many times as there are decimal places in both factors combined.
Remove the unnecessary zeros
The result is 260
842.4+260
Add the numbers

Answer:
I think it would be 1 and 3
Step-by-step explanation:
The correct answer is the first, second, and third.
1st Option-
This is pretty simple if you understand how a number line works. All the numbers on the right side are greater no matter what.
2nd Option -
All numbers on all sides could be rational, as we don't know what kind of number line this is.
3rd Option-
This is also correct because like the previous statement, the number line is unknown. We could have repeating numbers as long as the ones on the left side are less than the ones on the right.
4th Option -
This is incorrect because no matter what number line you have, the numbers on the left side are ALWAYS less than the ones on the right.

In the video game Fantasy Farm, it takes 5 6 6 5 start fraction, 5, divided by, 6, end fraction of a minute to harvest magic flowers, and it takes 5 6 6 5 start fraction, 5, divided by, 6, end fraction of an hour to build a golden barn. Which takes more time?
Answer:
Building gold barn takes more time
Step-by-step explanation:
Time to harvest magic flowers = 5/6 of a minutes
Time to build a gold barn = 5 / 6 of an hour
1 hour = 60 minutes
Time to build a gold barn = 5 / 6 of 60 minutes
= 5/6 × 60 minutes
= 50 minutes
= 50 minutes × 60 seconds
= 3,000 seconds
Time to harvest magic flowers = 5/6 of a minutes
1 minutes = 60 seconds
= 5/6 × 60 seconds
= 50 seconds
Building gold barn takes more time

Bus A and Bus B leave the bus depot at 9 am. Bus A takes 30 minutes to complete its route once and bus B takes 40 minutes to complete its route once. If both buses continue to repeat their route, at what time will they be back at the bus depot together?
Answer:
11 am
Step-by-step explanation:
Bus A and Bus B leave the bus depot at 9 am.
Bus A takes 30 minutes to complete its route once
Bus B takes 40 minutes to complete its route once.
We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route
30 = 3 × 10
40 = 4 × 10
= 3 × 4 × 10
= 120 minutes
120 minutes after 9 am is
60 minutes = 1 hour
60 minutes = 1 hour
= 2 hours.
9am + 2 hours
= 11 am.
Therefore, they be back at the bus depot together at 11 am

if c u means 20cd determine the value of 4 how to do maths how to do maths
Answer
4
Step-by-step explanation:
Lets assume that the variable "cu" is equal to 20cd. The value of this is 4. now we cancel out c from both sides, and get u = 20d = 4. Meaning d is 5, and u is 4. Lastly, u isnt a defined variable, so this shall work for any case.

When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
Mark's final velocity at the end of the 8 seconds is 9.6 m/s
Step-by-step explanation:
The acceleration of mark after the light turns green, a = 1.8 m/s²
The time duration of the motion with the 1.8 m/s² acceleration, t = 8 seconds
Mark's final velocity at the end of the 8 seconds, v is found using the equation of motion for velocity as follows;
v = u + a × t
Where;
u = The initial velocity = 0 m/s
a = The acceleration = 1.8 m/s²
t = The time in motion = 8 seconds
Substituting gives;
v = 0 + 1.2 × 8 = 9.6
Mark's final velocity at the end of the 8 seconds, v = 9.6 m/s.
Final velocity after 8 second is 64 m/s
Final Velocity of car:Given:
Acceleration of mark = 8 m/s²
Time taken = 8 second
Find:
Final velocity of mark
Computation:
v = u + at
v = 0 + (8)(8)
v = 64 m/s
Final velocity of mark = 64 m/s

Identify the range of the function shown in the graph.
Answer: [tex]-1 \le y \le 1[/tex]
The range is the set of all possible y outputs of a function. The graph shows the smallest possible y value is y = -1, while the largest is y = 1. The value of y can be anything in between.
If you need the range in interval notation, then you would write [-1, 1]. The square brackets indicate we include each endpoint.
Note: This is likely the graph of y = sin(x)

A frozen dinner at a grocery store is purchased for $2.20 wholesale and is marked up by 40 percent. A customer wants to buy four frozen dinners. How much will the customer pay, including paying 9 percent sales tax? Round your answer to the nearest cent. $8.80 $10.07 $13.43 $14.39
Answer:
$13.43
Step-by-step explanation:
Given that :
Price of dinner wholesale = $2.20
Markup % = 40%
Hence, selling price = (100 + 40)% * $2.20
Selling price = 140% * $2.20
Selling price = 1.4 * $2. 20 = $3. 08
Hence, price of 4 frozen dinner :
$3. 08 * 4 = $12.32
9% sales tax:
9% * $12.32
0.09 * $12.32 = 1.1088
Total amount paid :
$(12.32 +. 1.1088)
= $13.4288
= $13.43

The answer is $13.43
