In an expression, there are terms, which are a number(s) that are combined by multiplication but separated by addition (if you see subtraction it's just adding the negative version of the number). In this case, there are 5 terms. A term can have a variable or it can be a constant. A constant is just a number. We can combine constants. For example, in this case, we can combine 22 and -8 to get 14. (just adding). If it has a variable, we can only combine two terms if they have the same variable, so 5m and -4m can be combined to get m. We replace the terms we have combined with the combined terms so we have m + 7n + 14.

The cone shown has a diameter of 16 m and a slant height of 10 m which choice is the closest to the lateral surface area
Answers
Answer: 251 square meters.
Step-by-step explanation:
You need to use the formula for calculate the lateral surface area of a cone:
[tex]LA=3.14rl[/tex]
Being "r" the radius of the cone and "l" the slant height.
Calculate the radius:
[tex]r=\frac{diameter}{2}\\\\r=\frac{16m}{2}\\\\r=8m[/tex]
Now that you know the radius and the slant height of the cone, you need to substitute them into the formula for calculate the lateral surface area of the cone:
[tex]LA=(3.14)(8m)(10m)\\LA=251.2m^2[/tex]
Therefore, the closest choice to the lateral surface area of the cone is: 251 square meters.

Eliminate the parameter.
x = t + 4, y = t2 (5 points)
y = square root of x + x + 4
y = square root of quantity x minus four
y = x2 + 16
y = x2 - 8x + 16
Answers
Answer:
Last option
Step-by-step explanation:
We have the following equations:
[tex]x = t + 4\ ,\ \ y = t ^ 2[/tex]
The parameter that we must eliminate is t.
To eliminate the parameter we must clear t from both equations:
[tex]x = t + 4\\\\x -4 = t[/tex]
[tex]y = t ^ 2\\\\\sqrt{y} = t[/tex]
if [tex]t = \sqrt{y}[/tex] and [tex]t = x-4[/tex]
So:
[tex]\sqrt{y} = x- 4[/tex]
We square both sides of the inequality
[tex]y = (x-4) ^ 2\\\\y = x ^ 2 -8x +16[/tex]
Parallel lines are preserved in which of the following types of transformations?
Answers
Parallel lines are preserved in:
Reflections, Translations & Rotations
Parallel lines maintain their geometric property of not intersecting through all three transformations: rotations, reflections, and translations. Therefore, the correct answer is Option B. l, II, and III.
Explanation:In the field of mathematics, particularly in geometry, transformations involve the manipulation of shapes while preserving their essential properties. In the case of parallel lines, their key property is that they do not intersect, regardless of their length.
Out of the transformations listed - rotations, reflections, and translations - parallel lines are preserved in all three. Therefore, your answer is Option B. l, II, and III.
Specifically, a rotation spins the figure around a fixed point, a reflection flips the figure over a line, and a translation slides the figure along a straight line, parallel to the original lines. In all these transformations, the lines remain parallel to each other.

Order the expressions from least value to greatest value.
Answers
-4.8 • 3.2 = -15.36 (negative times a positive is negative)
2 1/4 + (-1 2/5) first find a common denominator, which would be 20
9/4= 45/20
-7/5 = -28/20
since adding a negative is the same as subtracting a positive, you would subtract 45 and 28 which is 17.
17/20 = 1 3/20 (the answer)
turn the fraction into a decimal by dividing the top number by the bottom number, so 17/20 = 0.85
4.92 divided by -3 equals -1.64 (the answer)
-2 3/5 - (-1 2/5)
make them into improper fractions which is -13/5 and -7/5
it stays negative, so the answer is -6/5 or -1.2
so the answer is
-4.8 • 3.2 < 4.2 divided by -3 < -2 3/5 - (-1 2/5) < 2 1/4 + (-1 2/5)
The order of the expressions from least value to the greatest value is Number 1 < Number 3 < Number 4 < Number 2 and this can be determined by using the arithmetic operations.

Amy handed out 79 donuts on National Donut Day. She still had 147 left to give out. Write and solve an equation to find out how much she started with.
Answers
[tex]x - 79 = 147[/tex]
147+79=226 Amy started with 226 donuts.
Final answer:
Amy started with 226 donuts. The equation x - 79 = 147 was solved by adding 79 to both sides to find x, representing the total amount of donuts she had originally.
Explanation:
The question involves solving a basic algebra problem to find the total number of donuts Amy started with. If Amy handed out 79 donuts and still has 147 left, we can set up the following equation where x represents the total number of donuts she originally had:
x - 79 = 147
To solve for x, we add 79 to both sides of the equation:
x - 79 + 79 = 147 + 79
x = 226
Therefore, Amy started with 226 donuts.
Which operation has an inverse relationship with multiplication? A. Addition B. Division C. Squaring D. Subtraction
Answers
Answer:
B. Division
Step-by-step explanation:
inverse - something that is the opposite or reverse of something else.
Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.
Division is the operation that has an inverse relationship with multiplication, as they 'undo' each other through the use of reciprocals.
Explanation:The operation that has an inverse relationship with multiplication is division. In mathematics, inverse operations are pairs of operations that 'undo' each other. Just as subtraction is the inverse operation of addition, division is the inverse when it comes to multiplication. When you multiply a number by another number, you can reverse this action by dividing the product by the same number.
To better grasp this concept, let's consider the relationship between multiplication and division with fractions. If we divide by 8, it is equivalent to multiplying by 1/8. Conversely, multiplying by 1/8 is the same as dividing by 8. Therefore, these two operations, multiplication and division, are interconnected through the use of reciprocals.

Macy's is having a special on t-shirts. You can buy each at its regular price of $10.99, $11.90 and $10.08 or you can buy 3 t-shirts for $25. Julie bought one of each t-shirt at the sale price of $25. What percentage of the original total price did Julie save?
Answers
Answer:
24.2%
Step-by-step explanation:
The total regular price was:
$10.99 + $11.90 + $10.08 = $32.97
She paid:
$25
She saved: $32.97 - $25 = $7.97
Now we need to calculate what percent of $32.97 is $7.97.
To find what percent a number is of another number, divide the first number by the second number and multiply by 100.
percent saved = $7.97/$32.97 * 100 = 24.2%
Part (b)
Harry, Julie's best friend, also paid $25 for 3 t-shirts at a sale at another store. The sale price saved Harry 30% of the original price of the 3 t-shirts. What is the original price of Harry's 3 t-shirts? Who got the better deal?
Harry paid $25 and saved 30% over his original price. Let his original price be x. The original price was 100% of the original price since 100% means the whole amount. Since he saved 30%, that means he paid 70% of the original price.
70% of the original price = $25
70% of x = 25
70%x = 25
0.70x = 25
0.70x/0.70 = 25/0.70
x = 35.71
The t-shirts Harry bought had an original price of $35.71.
Harry got the better deal because he bought t-shirts with an original higher price for the same $25.

Answers
Answer:
12'11" + 11'3" = 24'2".
Hope this helps!
Davinia.
To add 12'11" and 11'3", convert excess inches to feet and add them to the total feet to get a result of 24 feet 2 inches.
To add the lengths 12'11" and 11'3", we first add the inches (11 inches + 3 inches = 14 inches). Since there are 12 inches in a foot, we convert the 14 inches into 1 foot and 2 inches. We then add the feet (12 feet + 11 feet + 1 foot from the inch conversion = 24 feet). Therefore, the total length is 24 feet 2 inches.

This is an arithmetic sequence with common difference d between consecutive terms.
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][ 2a + (n - 1)d ]
where a is the first term
here a = - 6, d= 4 and n = 50, hence

2/5
How? The decimal .4 is out of ten so it’s 4/10 but then you simplify it and get 2/5
Hope this helps and have a blessed day!
Using the place value chart we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4 out of 10 or [tex]\frac{4}{10}[/tex]. Notice however that [tex]\frac{4}{10}[/tex] is not in lowest terms so we need to divide both the numerator and denominator by the greatest common factor of 4 and 10 which is 5.
Therefore, 0.4 can be written as the fraction 2/5, which is in lowest terms.
