whats the difference of 1cm and 1cm2
Answers
but 1 cm 2
means that you multiply 1 by 1 which is 1
for example if you have 15cm 2 you would multiply 15 by 15 and get 225
and 15 cm 3 would be 15*15*15 and you would get 3375
Final answer:
1 cm is a unit of length equal to [tex]10^{-2}[/tex], meter while [tex]1 cm^2[/tex]is a unit of area equal to 10^{-4} square meters.
Explanation:
The difference between 1 cm and 1 cm2 is that 1 cm is a measure of length, while 1 cm2 is a measure of area. To clarify, 1 cm is equivalent to 10-2 meters (or 0.01 meters), and it represents a one-dimensional measurement. In contrast, 1 cm2 is the area of a square with 1 cm long sides. When converting to square meters (m2), remember that the conversion factor for area is the square of the conversion factor for length. Therefore, 1 cm2 equals (10-2 m)2 or 10-4 m2.
Erica went shopping for new clothes for school. She bought a pair of jeans for $70.19 and several shirts for $8.63 each. If x represents the number of shirts she bought, which of the following equations should be used to find y, the total cost of Erica's shopping trip? Explain your choice.
plzzzz helpppp
Answers
To find the total she spent all you have to do is add everything together. The cost of the pants was $70.19, to find how much she spent on shirts you take the amount each shirt was, which in this case is $8.63, and multiply it by how many shirts she bought. We don't know how many shirts she bought so we use the varriable of X to represent that number.

When the new book Units of Fire was released, Jonathan decided to read it in one sitting for his book report. He started at 11:00 a.m. on Saturday morning and read until 8:00 p.m. that night, for a total of 9 hours. For school, however, he needed to record the exact number of minutes he spent reading.
How many minutes did he read?
...?
Answers
(Presuming he actually sat and read the whole time)
The total time in minutes that he spent in reading is:
540 minutes.
Step-by-step explanation:We are asked to find the total number of minutes Jonathan spent on reading on Saturday.
It was given that he read for a total of 9 hours.
Hence, we will convert this time to minutes by using the conversion:
As 1 hour= 60 minutes.
Hence, 9 hours= 9×60 minutes= 540 minutes.
Hence, the total time Jonathan spent in reading on Saturday is:
540 minutes.
Jen and Heather went to lunch. When the bill came Jen discovered that she had only 8.00 dollars, luckly Heather had enough money to pay the other part or 3/5 of the bill. ...?
Answers
Given that Heather paid the other part of the bill which is 3/5 of the bill, then this means that, Jen paid only 2/5 of the bill. Now that Jen has only 8 dollars, this 8 dollars is equivalent to 2/5 of the bill. The next thing we are going to find out is how much did Heather pay which is 3/5 of the bill.
So 2/5 = 8 dollars
3/5 = ?dollars
Therefore, the answer would be $12. The amount that Heather paid is $12. Hope this answer helps.

The intensity I of light bulb varies inversely as the square of the distance d from the light bulb. Suppose I is 250 w/m^2 when the distance is 5 m. How much farther would it be to a point where the intensity is 40 w/m^2? ...?
Answers
The intensity of a light bulb varies inversely as the square of the distance from the light bulb. To find the distance where the intensity is 40 w/m², use the inverse square law formula to solve for the distance.
Explanation:The intensity of a light bulb varies inversely as the square of the distance from the light bulb. This means that as the distance increases, the intensity decreases.
If the intensity is 250 w/m² at a distance of 5 m, and we want to find the distance where the intensity is 40 w/m², we can use the inverse square law formula:
I₁d₁² = I₂d₂²
Plugging in the values, we get:
250 × (5)² = 40 × (d₂)²
Simplifying, we find that d₂² = 250 × (5)² / 40
d₂² = 312.5
Therefore, d₂ = √312.5 ≈ 17.68
So, it would be approximately 17.68 - 5 = 12.68 meters farther to a point where the intensity is 40 w/m².

#SPJ12
Sure, let's solve it step by step.
First, we know that the initial intensity (I1) is 250 w/m^2 and the initial distance (d1) is 5 m. We are asked to find a distance where the intensity is 40 w/m^2, which would be our final intensity (I2).
According to the inverse square law, the intensity of light is inversely proportional to the square of the distance from the source, i.e., I ∝ 1/d². Therefore, we can say that I1 * d1² = I2 * d2². This equation allows us to find the distance at which the intensity is I2.
So, substituting the given values in the equation, we have 250 * (5)² = 40 * d2².
Now, we can solve for d2. Rearranging terms, d2 = √((250 * (5)²) / 40), which will give us d2 = 12.5 m.
So, the distance at which the intensity of light is 40 w/m^2 is 12.5 m.
However, we have been asked to find the additional distance that needs to be traveled to reach a point where the intensity is 40 w/m^2. This additional distance is the difference between the final distance (d2) and the initial distance (d1), that is, distance_travelled = d2 - d1 = 12.5 - 5 = 7.5 m.
Therefore, you would need to travel an additional 7.5 m to reach a point with an intensity of 40 w/m^2.

Solve the following equation for B
y=mx+b
Answers
__________
b = y − mx .
__________
Explanation:
__________
Given:
__________
y = mx + b ;
_________
We want to isolate "b" on one side of the equation to solve for "b".
_______________________
→ y = mx + b ; Subtract "mx" from BOTH sides of the equation; to isolate "b" one side of the equation; and solve for "b":
____________________________________
y = mx + b → y − mx = mx + b − mx ;
____________________________________
→ y − mx = b ; ↔ b = y − mx
____________________________________
→ b = y − mx .
____________________________________
To solve for b, you just have to replace x and y in the formula with the given coordinates and replace m with the calculated value.
For example, you have to find the equation of a line with the coordinate points (1, -2) and (6, 5). Replace one set of ordered pairs in the slope intercept formula.
Graph both of the coordinate points in a coordinate plane, or a graph, to find it's slope. Use rise over run. Simply count how many points it takes to go the other ordered pair.
The slope of (1, -2) and (6, 5) is 7/5.
If you found the slope, plug those numbers in.
I used (1, -2). I plugged in the slope.
-2 = 7/5(1) + b
You just have to solve for b by simplifying the equation.

To win at LOTTO in one state, one must correctly select 6 numbers from a collection of 62 numbers (1 through 62). The order in which the selection is made does not matter. How many different selections are possible? ...?
Answers
The number of different selections possible when picking 6 numbers from a collection of 62 numbers for a LOTTO game is 62,891,499.
Explanation:The question asks how many different selections are possible when picking 6 numbers from a collection of 62 numbers for a LOTTO game. Since the order of the selection does not matter, we can use the concept of combinations to solve this problem. The formula for combinations is given by C(n, r) = n! / (r! * (n-r)!), where n is the total number of items and r is the number of items selected. Plugging in the values, we have C(62, 6) = 62! / (6! * (62-6)!), which simplifies to 62! / (6! * 56!). Using a calculator or computer program to calculate the factorial, we find that C(62, 6) is equal to 62,891,499.
Final answer:
To find the number of different selections possible in a lotto where 6 numbers are chosen from 62, we use the combination formula: C(62, 6). This yields 45,057,474 possible selections.
Explanation:
Calculation of Different Selections in Lotto
To calculate the number of different selections possible when choosing 6 numbers from a set of 62 without regard to the order of selection, we use the combination formula:
The combination formula is C(n, r) = n! / (r! * (n-r)!), where C(n, r) is the number of combinations, n is the total number of items to choose from, r is the number of items to be chosen, and ! denotes factorial.
In this case, n = 62 and r = 6:
C(62, 6) = 62! / (6! * (62-6)!) = 62! / (6! * 56!)
Calculating the factorials and the division, we find that there are 45,057,474 possible selections.
Therefore, the probability of winning by correctly selecting all 6 numbers is 1 in 45,057,474, making lottery tickets a game of very low probability for individual success.

Answers
Hope this helps you
To subtract the polynomials, change the signs of the second polynomial and combine like terms. The result is -6m² + 11m - 6, which is option D.
To subtract the given polynomials, we need to subtract the second polynomial from the first one. We do this by changing the signs of the second polynomial and then combining like terms with the first.
(m² + 6m - 5) - (7m² - 5m + 1) becomes (m² + 6m - 5) + (-7m² + 5m - 1).
Now, combine the like terms:
m² - 7m² = -6m²,6m + 5m = 11m,-5 + (-1) = -6.So, the simplified form of the polynomial after subtraction is -6m² + 11m - 6, which corresponds to option D.

A right triangle is removed from a rectangle to create the shaded region shown below. Find the area of the shaded region. Be sure to include the correct unit in your answer.
Answers
[tex]a=8-5=3 \\ b=6-4=2 \\ \\A=A_{rectangle}-A_{triangle}=8\times 6- \frac{ab}{2} =48-\frac{3\times2}{2}=48-3=45[/tex]
Answer:
The area of shaded region is 45 square units.
Step-by-step explanation:
The length of the rectangle is 8 and the breadth is 6.
Area of rectangle is
[tex]A_R=l\times b[/tex]
[tex]A_R=8\times 6=48[/tex]
The area of rectangle is 48 square units.
Since the opposite sides of a rectangle are equal, therefore the legs of the right angled triangle are
[tex]l_1=8-5=3[/tex]
[tex]l_2=6-4=2[/tex]
The area of right angled triangle is
[tex]A_T=\frac{1}{2}\times l_1\times l_2[/tex]
[tex]A_T=\frac{1}{2}\times 3\times 2=3[/tex]
The area of triangle is 3 square units.
The area of shaded region is
[tex]A=A_R-A_L=48-3=45[/tex]
Therefore the area of shaded region is 45 square units.
