Final answer:
To find the current year's average temperature of Kopikoville, add the increase of 10°C to last year's temperature of -19°C, which results in an average temperature of -9°C for this year, making the correct answer option A.
Explanation:
The question asks to determine the current year's average temperature of Kopikoville based on the last year's average temperature and the change that occurred this year. To calculate this, we consider last year's average temperature of Kopikoville, which was -19°C, and we add the increase in temperature this year, which was 10°.
We perform a simple addition: -19°C + 10°C, which equals -9°C. Thus, this year's average temperature of Kopikoville is -9°C. The correct answer is option A.

The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?
Answer:
104
Step-by-step explanation:
First, put the word equation into a numerical equation.
-4+5x=7x-212 This is our equation
-4=2x-212 I subtracted 5x from both sides
208=2x I added 212 to both sides
104=x I divided both sides by 2
To solve the problem, we can set up an equation and solve for the variable 'x'. The number is x = -25.
Explanation:To solve this problem, we can translate the given information into an equation. Let's assume the number is 'x'. The sum of -4 and 5 times 'x' is -4 + 5x. The equation becomes 3(-4 + 5x) = 7x - 212. We can simplify this equation and solve for 'x' to find the number.
First, distribute the 3 to -4 and 5x, which gives us -12 + 15x = 7x - 212. Then, combine like terms by subtracting 7x from both sides, which gives us -12 + 8x = -212. Next, add 12 to both sides to isolate the variable, resulting in 8x = -200. Finally, divide both sides by 8 to solve for 'x'. The number is x = -25.

I need help with this question please I’ll mark as brainliest
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 14), thus
y = a(x - 8)² - 14
To find a substitute (5, 13) into the equation
13 = a(5 - 8)² - 14
13 = a(- 3)² - 14
13 = 9a - 14 ( add 14 to both sides )
27 = 9a ( divide both sides by 9 )
a = 3
Thus
y = 3(x - 8)² - 14 → C
You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 6 ft. The base of the incline plane is 10 ft from the shelving unit. What is the length of the incline plane?
To determine the length of an inclined plane given the height (6 ft) and base (10 ft), use the Pythagorean theorem, which reveals that the length of the inclined plane is approximately 11.66 feet.
Explanation:The student is asking about the length of an inclined plane when given the height and the base of the incline. To find the length of the inclined plane, we can use the Pythagorean theorem because the height, base, and the length of the incline form a right triangle.
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the hypotenuse is the length of the incline, the vertical side is the height of the shelving unit (6 ft), and the horizontal side is the base of the incline (10 ft).
The formula is: length of the incline2 = height2 + base2. Plugging in the numbers, we get: length of the incline2 = 62 + 102, which simplifies to length of the incline2 = 36 + 100. The square root of 136 gives us the length of the incline, which is approximately 11.66 feet.

The sum of three consecutive numbers is 42. What are the three numbers?
Answer:
13,14,15
Step-by-step explanation:
Let x be the first number
x+1 is the second number
x+2 = third number
x+ x+1 +x+2 = 42
Combine like terms
3x+3 =42
Subtract 3 from each side
3x+3-3 = 42-3
3x = 39
Divide each side by 3
3x/3 = 39/3
x = 13
The numbers are 13
13+1 =14
13+2 = 15
Answer:
13,14,15
Step-by-step explanation:
What three consecutive integers have a sum of 42? Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.

X=5.6
The value of X= 5.6
Answer:

Step-by-step explanation:
Expressing the ratio in fractional form, that is
[tex]\frac{5x}{8}[/tex] = [tex]\frac{7}{2}[/tex] ( cross- multiply )
10x = 56 ( divide both sides by 10 )

A cylinder has a base radius of 6 inches and a height of 14 inches. What is its volume
in cubic inches, to the nearest tenths place?
Final answer:
The volume of the cylinder is 1580.64 cubic inches.
Explanation:
To find the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius of the base, and h is the height.
In this case, the radius, r, is 6 inches and the height, h, is 14 inches.
So, the volume is calculated as follows:
V = π(6²)(14) = 3.14(36)(14) = 1580.64 cubic inches.

Step-by-step explanation:
Trust me, I kept googling this for almost an hour.
The Average of the Dinner is 20.66.
What is Average?In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.
The data for dinner is:
18.8, 22.13, 20.79, 24.82, 16.74
The Average of the Dinner is
= ( sum of all data for dinner)/ Total Number of Dinner
As, sum of all data for dinner = (18.8 + 22.13 + 20.79 + 24.82 + 16.74)
=103.28
and, Total Number of Dinner = 5
Now put the values we get
= (18.8 + 22.13 + 20.79 + 24.82 + 16.74) / 5
= 103.28/ 5
= 20.656
= 20.66
Thus, the average of the dinner is 20.66
