Step-by-step explanation:
Devin brought his snail collection to school. He has 10 snails.
the smallest number of snails in the tank is 0 and the greatest number of snails in the tank is 10. Also the number of snails in each tank must be a whole number (Devin cannot put half of the snail into the tank). There are 11 whole numbers between 0 and 10.
Hence, all 11 possibilities to divide snails into two tanks are:
[tex]\begin{array}{cc}\text{Tank 1}&\text{Tank 2}\\ \\0&10\\1&9\\2&8\\3&7\\4&6\\5&5\\6&4\\7&3\\8&2\\9&1\\10&0\end{array}[/tex]
The sums of two numbers in each row must be exactly 10 as the total number of snails Devin has.

The quotient of a number 2 is 7
Answer:14
Step-by-step explanation:
I need help, if you can help me I’ll be real thankful
Answer:
x^2-6x+7
Step-by-step explanation:
You can use synthetic division since you are dividing by a linear factor with leading coefficient 1. (You can also do synthetic division when dividing by a linear factor whose leading coefficient is not 1 but it is a bit trickier.)
So since we are dividing by x-2, 2 goes on the outside.
(If we were dividing by x+2, -2 would go on the outside.)
Now the thing that goes on top inside is the dividend, the numerator which is 1x^3-8x^2+19x-14. If you were missing any terms you would have to place a zero but we aren't. All exponents between 3 and 0 (inclusive meaning to include the 3 and the constant term) on variable x is accounted for.
2| 1 -8 19 -14
| 2 -12 14
-----------------------------
1 -6 7 0
So the remainder is 0 and the quotient is x^2-6x+7.

Gary and Ann have a joint checking account. Their balance at the beginning of October was $9145.87.
During the month they made deposits totaling $2783.71, wrote checks for $4871.90, paid a maintenance
fee of $12, and earned $11.15 in interest on the account. What was the balance at the end of the month?
Answer:
The balance at the end of the month was $7,056.83
Step-by-step explanation:
we know that
The balance at the end of the month is equal to the balance at the beginning of the month plus deposits and interest minus checks and maintenance fee
so
9,145.87+(2,783.71+11.15)-(4,871.90+12)
9,145.87+(2,794.86)-(4,883.90)=$7,056.83
Answer:
The balance was $ 7,056.83
Step-by-step explanation:
Given,
The original balance in beginning of the month = $9145.87,
The amount of deposit = $2783.71,
So, new balance after depositing = $9145.87 + $2783.71 = $ 11929.58,
Check amount = $4871.90,
After clearing check, the new balance = $ 11929.58 - $ 4871.90 = $ 7057.68,
Also, after charging $ 12 fees, new balance = $ 7057.68 - $ 12 = $ 7045.68,
Finally getting $ 11.15 interest,
The final balance at the end of month = $ 7045.68 + $ 11 = $ 7,056.83

Lia claims that a reflection over the y-axis will always carry a circle drawn on the coordinate plane to a circle with the same center and the same radius. Which statement best describes Lia's claim?
A
Lia is correct as a reflected circle will always have the same center and always have the same radius as the original circle.
B
Lia is incorrect as a reflected circle will not always have the same radius and will not always have the same center as the original circle.
C
Lia is correct in stating that the reflected circle will always have the same radius, but is incorrect in stating that the reflected circle will always have the same center.
D
Lia is incorrect in stating that the reflected circle will always have the same radius, but is correct in stating that the reflected circle will always have the same center.
Answer: YOUR ANSWER WOULD BE B
Step-by-step explanation: Your answer would be B because when you reflect something on the y-axis it always goes one cube or dashed line forward so it will not have the same radius nor the circle hope this helps you alot
Answer:
C. Lia is correct in stating that the reflected circle will always have the same radius, but is incorrect in stating that the reflected circle will always have the same center.Step-by-step explanation:
Lia's claim is not correct, because when we reflect a figure, its coordinates variate. In this case, Lisa is trying to reflect a circle over the y-axis, which will change y-axis coordinates. The center of the circle is gonna change its y-axis coordinate, for example, if the center is [tex]C(2;3)[/tex], its reflection will be [tex]C(2;-3)[/tex]
Therefore, the center of the circle will not remain the same. However, the radius will be the same, because changing y-axis coordinates don't affect the distance between the center and the circumference of the circle.
So, the correct answer is option C.

One of two supplementary angles is 70° greater than the second.
Find the measure of the larger angle.
Answer:
125°
Step-by-step explanation:
Supplementary angles sum to 180°
let one angle be x then the larger angle is x + 70, thus
x + x + 7 0 = 180
2x + 70 = 180 ( subtract 70 from both sides )
2x = 110 ( divide both sides by 2 )
x = 55
Hence
larger angle = x + 70 = 55 + 70 = 125°

The student is working with scientific notation, specifically converting 6 x [tex]10^{-3}[/tex] into standard notation, which results in the number 0.006.
The student in question appears to be dealing with scientific notation and its application in representing large or small numbers in a condensed form. In scientific notation, numbers are represented as a product of a base number and 10 raised to a certain power. For instance, 6 x 10/3 is a way to represent the number 0.006, indicating the decimal point has been moved three places to the left.
To convert 6x10/3 into standard notation, you need to recognize that the exponent -3 on the 10 denotes how many places to move the decimal. Since it is negative, we move the decimal to the left. Therefore, we rewrite 6 as 0.006, which is the standard notation.
The width of a rectangular football fields is 14 meters more than half of its length. If L represents the length of the field, write an expression for the width.
Answer:
w = 14 - (L/2)
Final answer:
The width, W, of the rectangular football field is expressed as W = (1/2)L + 14, which signifies that the width is half of the field's length plus an additional 14 meters.
Explanation:
If L represents the length of the football field, the expression for the width, W, is W = rac{1}{2}L + 14. This is because the width is given as 14 meters more than half of the field's length. So, to write this relationship as an expression, we start by taking half of the length, denoted as [tex]rac{1}{2}L[/tex], and then add 14 meters to this value to account for the additional width.

Jesse multiplied 12 by 0.23. Without calculating will the product be more or less than 12 ? Explain
Answer:
The product will be LESS than 12.
Step-by-step explanation:
When multiplying a number by something smaller than 1, the product will always be smaller than your first number. A simple way to remember this is that a decimal is the same as a fraction in almost every way. For example, 1/2 and .5 are the same number.
When a number is multiplied by a decimal less than 1, the product will always be less than the original number. Hence, if Jesse multiplies 12 by 0.23, the result will be less than 12.
To determine whether the product of multiplying 12 by 0.23 will be more or less than 12, we can use some basic estimation and mathematical reasoning without performing the actual calculation. Here's a step-by-step explanation:
Step 1: Understand the decimal value of 0.23.
- 0.23 is less than 1, which means it is a fraction of 1. In decimal form, it's less than 0.5 but greater than 0.2.
Step 2: Understand the concept of multiplication with fractions less than 1.
- When you multiply a number by a fraction less than 1, the result is smaller than the original number. The closer the fraction is to 0, the smaller the result.
Step 3: Apply this understanding to the problem.
- Since 0.23 is less than 1 and closer to 0, when you multiply 12 by 0.23, the result will be smaller than 12.
Step 4: Answer the question.
- Therefore, the product of multiplying 12 by 0.23 will be less than 12.
So, without calculating the actual product, we can confidently say that the result will be less than 12 because we are multiplying 12 by a fraction (0.23) that is less than 1.

Final answer:
The value of 1 raised to any power, including 1 exponent 102, is 1. When you multiply 1 by itself any number of times, the result is always 1 because the identity property of multiplication states that any number multiplied by 1 remains unchanged.
Explanation:
The value of 1 exponent 102, or $1^{102}$, is 1. In fact, the value of any power of 1 is always 1. To understand this, let's think of the exponent as how many instances of a number are multiplied together. When you multiply 1 by itself any number of times, the result remains 1 because multiplying by 1 does not change the value of the original number. Thus, 1 to any power, whether it's 1 or 102, will still give us 1.
Using these principles, let's address another problem without entering scientific notation into your calculator. To evaluate $(4.506 \times 10^4) \times (1.003 \times 10^2)$, we can multiply the coefficients (4.506 \times 1.003) and then add the exponents of 10 (4 + 2), since when powers of 10 are multiplied together, the exponents are added. The result is approximately 4.514518 \times 10^6.
