please help this is homework and I don’t know how to do it!!!
Step-by-step explanation:
you don't understand what the multiplication or division with 10 (or a higher power of 10) does ?
or you don't know. what 10² means ?
this means 10 to the power of 2 or 10 squared and is simply 10 multiplied with itself 2 times : 10×10.
and 10×10 is ... 100.
as you can imagine, this is not restricted to the number 2 (and 10). "power of" can be any number and just indicates how often the base number is multiplied with itself.
a surcharge case is "power of 0", which is simply 1.
now that we understand that, let's have a quick look at how the numbers we are dealing with (in daily life as well as in class and in science) are actually built :
when I write e.g the number
1234
then this actually means
4×10⁰ + 3×10¹ + 2×10² + 1×10³
when I multiply this now by e.g. 10 this becomes
4×10⁰×10 + 3×10¹×10 + 2×10²×10 + 1×10³×10 =
4×10¹ + 3×10² + 2×10³ + 1×10⁴
as you can see, the previous "single" position 4 now becomes a 40.
and the result looks in short form :
12340
so, a multiplication by 10 adds a 0 at the low end of the number.
a multiplication by 10² or 100 (= 10×10) adds then 2 0s at the low end. and so forth.
a division by 10 does the opposite and removes a 0 at the low end of the number.
but what if we don't have any 0 at this position of the number ? then we enter the system of the decimal point.
because on the right side of the decimal point we continue to countdown the exponent of 10 below 0.
the first position right of the decimal point stands for 10^‐1, the second position for 10^‐2, and so forth. and that is nothing else than tenths, hundredths, thousandths, ...
so, in short, a multiplication by 10 moves the decimal point one position to the right. and if we run out of written positions, then we can simply assume an infinite sequence of 0s continuing further to the right.
and a division by 10 moves the decimal point one position to the left. and if we run out of written positions, then we can simply assume an infinite sequence of 0s continuing further to the left too that are then showing up on the right side of the decimal point.
now, I think we covered all the basics and we can look at the question here :
10² × 18.72
10² = 100 = 10×10
so, we are multiplying twice by 10 and move the decimal point therefore 2 positions to the right.
the result is then
1872
as a little guide : when it is clear that the number has to get bigger by the operation (like a multiplication by 10 or 100), you need to move the decimal point in the direction that makes the number bigger (which is to the right).
and if the operation is clearly trying to make the number smaller, then you have to move the decimal point in the direction to make the number smaller (to the left).
can anyone help me if so Ty no file answers please.

A group spends $277.50 to rent a total of 15 tubes. How many of each type of tube does the group rent?
The amount spent on each tube is $18.5
The total amount spent to rent 15 tubes by the group is $277.50.
Since they did not specify in the question the types of tubes they rented, we cannot determine each types of tubes that the group rented but we can determine the amount spent on each tube provided that they are all the same types.
∴
if 15 tubes = $277.50
1 tube = $x
By cross multiplying:
[tex]\mathbf {\$(x) = \dfrac{ \$277.50 \times 1 \ tube }{15 \ tube}}[/tex]
[tex]\mathbf {(x) = \$18.5}[/tex]
Therefore, we can conclude that the amount spent on each tube is $18.5

Michael-Anthony runs 3 Miles in 20 Minutes.
Jocelyn Runs 4 Miles in 30 Minutes.
Continues at pace for 1 Hour.
Questions that Need to be Answer:
How many miles does each person each person run in an hour?
Who runs faster?
Explanation/Solution:
So, We know that 1 Hour = 60 Minutes and three 20 minutes equal 60 Minutes also known as 1 Hour..
Since, three 20 minutes equal 1 Hour that means
Micheal-Anthony Run 6 Miles a Hour adding the 20 Minutes equal 9 Miles
Hence, Micheal-Anthony Run 9 Miles..
We know that 1 Hour = 60 Minutes and two 30 Minutes equal 60 Minutes also known as 1 Hour..
Since, two 30 Minutes equal 1 Hour that means
Jocelyn Run 8 Miles a Hour adding the 30 Minutes equal 12 Miles
Hence, Jocelyn Run 12 Miles..
For these Reason, You can tell that Jocelyn Run 8 Miles an Hour and Micheal-Anthony Run 6 Miles a Hour and Jocelyn Run Faster than Micheal-Anthony.

Last week, Byron bought 5 containers of yogourt and spent $12.88 on other groceries.
This week casandra bought 3 containers of the same yogourt and spent $11.50 on other groceries. How much more money did byron spend than casandra
Answer:
Byron spent 0.62 cent more than Casandra.
Step-by-step explanation:
It says how much more money did Byron spend than Casandra?
So you have to take how much Byron had and subtract it by how much Casandra had.
$12.88 - $11.50 = $0.62
And that's how you get your total on how much more did Byron spend than Casandra.

Find the values of x and y
Answer:
y=30
x=60
Step-by-step explanation:
The triangle has all sides equal therefore all the angles are equal.
For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.
Therefore y=90-60
=30
x=180-(30+90)
=60

Fewer than 9
At least 9
Greater than 9
Answer:
Step-by-step explanation:
AT LEAST 9
Millie's account will be above $750 for weeks greater than 9.
What is inequalities?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Millie has a bank account balance of $1,497. Each week, her balance changes by - $83. She wants to keep the balance above $750.
Establishing an inequality,
750 > 1497 - 83x
Where, x is the number of weeks.
On solving, we get,
747 > 83x
x < 9
Hence, Millie's account will be above $750 for weeks greater than 9.

knife is 3 times cost of spoon
9 spoons and 12 knifes is £82.80
what is 1 knife
Answer:
The cost of spoon is £1.84 and therefore the cost of one knife is £5.52.
Given :
A knife is 3 times the cost of the spoon. 9 spoons and 12 knives costs £82.80.Solution :
This question is solve by creating a linear equation and linear equations are nothing but yet another subset of "equations". Linear calculations that requires more than one variable can be done with the help of linear equations. The standard form of a linear equation in one variable is ax + b = 0.Now let x be the cost of spoon. Than the cost knife is 3x. It is given that 9 spoons and 12 knives costs £82.80.
[tex]9x + 12 x (3x) = 82.809x + 36x = 82.8045x = 82.80x = 1.84[/tex]
