Answer:
3.28*10^(10) text messages.
Step-by-step explanation:
We know that there are about 41,000,000 teenagers in the US.
If each one of they sent an average of 800 text messages, then the total number of text messages sent in a month is something about:
Total number of messages = 41,000,000*800 = 32,800,000,000
Now we want to write this in scientific notation.
To do it, we need to count the number of digits at the left of the decimal point, if there are N total digits, we can write our number as:
3.28*10^(N - 1)
Where we now have only one digit at the left of the decimal point.
Here we have 11 digits.
Then we can write this number as:
3.28*10^(11 - 1)
3.28*10^(10)
12=24-y
help me pleaseee
Answer:
y=12
Step-by-step explanation:
12=24-y
step 1
subtract each side by 24
24-24 cancels out
12-24=-12
now we have
-y=-12
we now have to divide by -1
-1/-1=1
-12/-1=12
so we can conclude that y=12
Answer:
y = 12
Step-by-step explanation:
12=24-y
y = 24 - 12
y = 12

Liam has $62. He saves an equal amount of money each week for 6 weeks. Now he has $110. How much money did Liam save each week?
Answer:
Step-by-step explanation:
Liam saved $8 each week for 6 weeks.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's represent the amount of money Liam saves each week as x.
According to the problem, Liam saves an equal amount of money each week for 6 weeks, so the total amount he saves is 6x.
If we add this to the amount he started with, we get the total amount he has now: 6x + 62.
We also know that he now has $110, so we can set up an equation:
6x + 62 = 110
Subtracting 62 from both sides gives:
6x = 48
Dividing both sides by 6 gives:
x = 8
Therefore,
Liam saved $8 each week for 6 weeks.

Basically there is 180 degrees in every triangle. So all you do is
180-76=104
104-41= 63
so your answer is 63 degrees.

The price of a cycle after allowing 15% discount and 13% VAT is Rs.19,323. Find the amount of VAT levied and marked price.
Answer:
Rs. 18936.54
Step-by-step explanation:
Given data
Discount=15%
VAT= 13%
Amount paid= Rs.19,323
The amount of VAT
=13/100*19323
=0.13*19323
= Rs. 2511.99
The amount of discount
=15/100*19323
=0.15*19323
= Rs.2898.45
The marked price is
=19323+2511.99-2898.45
=21834.99-2898.45
=Rs. 18936.54

Answer: $4110.8 (more likely - 95% sure) or $2,107 (less likely)
Step-by-step explanation: It could be $4110.8 because you have the take the total they made and subtract is from the cost of the toys ($7,230-$2,450=$4,780). Then you have to take the result of that and get 14% of it, then subtract that from the $4,780 amount. Then you get the final answer which is $4110.8.
However, it could also be $2,107 because the question itsn't that clear in the second sentence. It could be saying that $2,450 is the price of the toys (which is what I assumed above), or that it is the profit that the $2,450 (which I used below). I think that the above answer is more likely because if not then the first number would never be used. Anyways here is the second way it could be.
Step-by-step explanation: It could be $2,107 because you take the profit ($2,450) and get 14% of it, then subtract that from the $2,450 amount. Then you get the final answer which is $2,107.
If I was you, I would do the first one ($4110.8) because I really think it is that one. I just put the other one here just in case.
