O 8
O 10
O 11
O 12
Answer: so are you saying that 8+14x because I don’t know what you write so here the answer
Step-by-step explanation: Hope this help :D
Evaluate for x=10
8+(14)(10)
8+(14)(10)
=148
But if you don’t want that then I will guess the answer is C.11
The value of x is 8
Given: 8, 14, x
Average = 10
Then,
(8 + 14 + x) / 3 = 10
Cross product
(8 + 14 + x) = 3 × 10
22 + x = 30
x = 30 - 22
x = 8

dividing 1/9 is equal to multiplying by
Answer: 9
Step-by-step explanation: To divide we need to flip the second fraction we are dividing by. For example:
10/1 divided by 1/4 = 10/1 times 4/1. So in this case, the answer is 40.
Now lets try it with 1/9.
X divided by 1/9 = X times 9/1.
So dividing by 1/9 is equal to multiplying by 9.

Andy painted 400 square feet in 3 hours. At that rate, how many cars could they wash in 7 hours? *
Answer:
It will take 5.4 hour to paint 720 square feet
Step-by-step explanation:
The question should be like this"Andy painted 400 square feet in 3 hours. How long would it take him to paint 720 square feet?"
In 3 hours = 400 square feet is painted
1 square feet is painted in \(\dfrac{3}{400}\ h\)
To find time to paint 720 square feet multiply the above term by 720 as follows :
\(720\ ft^2=\dfrac{3}{400}\times 720\ h\\\\=5.4\ h\)
So, it will take 5.4 hour to paint 720 square feet.

The area of a rectangle is 16 1/3 square inches.The width is 4 2/3. Inches.Find the length
Answer:
Let the length of the rectangle be L. Then we can use the formula for the area of a rectangle:
Area = Length x Width
Substituting the given values, we get:
16 1/3 = L x 4 2/3
To solve for L, we can first convert the mixed numbers to improper fractions:
16 1/3 = 49/3
4 2/3 = 14/3
Substituting these values, we get:
49/3 = L x 14/3
To solve for L, we can multiply both sides by the reciprocal of 14/3:
49/3 ÷ 14/3 = L
Simplifying, we get:
L = 49/3 x 3/14
L = 7/1
L = 7
Therefore, the length of the rectangle is 7 inches.

find the derivative of the function using the definition of the derivative. state the domain of the function and the domain of its derivative. f (t) = 2.5t2 +6 t
Using the definition of the derivative, the derivative of the function is f'(t) = 5t + 6. The domain of the function and its derivative are both the set of all real numbers.
The derivative is a concept in calculus that represents the rate of change or the slope of a function at a specific point. It is defined as the limit of the difference quotient of the function as the interval between the two points approaches zero. Mathematically, the derivative of a function f(x) at a point x is represented as f'(x) and can be expressed as:
f'(x) = lim h -> 0 [f(x + h) - f(x)]/h
where h is the interval between the two points.
The derivative is a fundamental tool for analyzing and understanding the behavior of functions, including their local maxima, minima, and inflection points, as well as for solving problems in physics and engineering.
The derivative of the function f(t) = 2.5t² + 6t can be found using the definition of the derivative:
f'(t) = limit as h -> 0 of [f(t + h) - f(t)]/h
= limit as h -> 0 of [2.5(t + h)² + 6(t + h) - (2.5t² + 6t)]/h
= limit as h -> 0 of [2.5t² + 5ht + 2.5h² + 6t + 6h - 2.5t² - 6t]/h
= limit as h -> 0 of [5ht + 2.5h² + 6h]/h
= limit as h -> 0 of [5t + 2.5h + 6]
= 5t + 6
The domain of the function f(t) = 2.5t^2 + 6t is all real numbers. The domain of its derivative f'(t) = 5t + 6 is also all real numbers.

Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2
The three equivalent equations are 2 + x = 5, x + 1 = 4 and -5 + x = -2. So, correct options are A, B and E.
Two equations are considered equivalent if they have the same solution set. In other words, if we solve both equations, we should get the same value for the variable.
To determine which of the given equations are equivalent, we need to solve them for x and see if they have the same solution.
Let's start with the first equation:
2 + x = 5
Subtract 2 from both sides:
x = 3
Now let's move on to the second equation:
x + 1 = 4
Subtract 1 from both sides:
x = 3
Notice that we got the same value of x for both equations, so they are equivalent.
Next, let's look at the third equation:
9 + x = 6
Subtract 9 from both sides:
x = -3
Since this value of x is different from the previous two equations, we can conclude that it is not equivalent to them.
Now, let's move on to the fourth equation:
x + (-4) = 7
Add 4 to both sides:
x = 11
This value of x is also different from the first two equations, so it is not equivalent to them.
Finally, let's look at the fifth equation:
-5 + x = -2
Add 5 to both sides:
x = 3
Notice that we got the same value of x as the first two equations, so this equation is also equivalent to them.
So, correct options are A, B and E.

Figure Y is the result of a transformation on Figure X. Which transformation would accomplish this?
A. a reflection over the x -axis
B. a rotation 90° clockwise about the origin
C. a rotation 180° counterclockwise about the origin
D. a translation 10 units to the left and 10 units down
A transformation would accomplish this include the following: C. a rotation 180° counterclockwise about the origin.
What is a rotation?In Mathematics and Geometry, the rotation of a point 180° about the origin in a clockwise or counterclockwise direction would produce a point that has these coordinates (-x, -y).
Furthermore, the mapping rule for the rotation of a geometric figure 180° counterclockwise about the origin is given by this mathematical expression:
(x, y) → (-x, -y)
Coordinates of point X (0, 4) → Coordinates of point Y = (0, -4)
Coordinates of point X (1, 3) → Coordinates of point Y = (-1, -3)
In conclusion, we can logically deduce that this transformation rule (x, y) → (-x, -y) would map Figure X onto Figure Y.

Certainly! The problem can be solved using the Pythagorean theorem,
which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the ladder acts as the hypotenuse, and we need to find the length of the vertical side (height) it reaches up the wall.
The ladder forms the hypotenuse, and its length is given as 12 meters. The distance from the foot of the ladder to the base of the wall represents one side of the triangle, which is 4.5 meters.
By substituting the given values into the Pythagorean theorem equation: (12m)^2 = h^2 + (4.5m)^2, we can solve for the unknown height 'h'.
Squaring 12m gives us 144m^2, and squaring 4.5m yields 20.25m^2. By subtracting 20.25m^2 from both sides of the equation, we isolate 'h^2'.
We then take the square root of both sides to find 'h'. The square root of 123.75m^2 is approximately 11.12m.
Therefore, the ladder reaches a height of approximately 11.12 meters up the wall.

Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
