Find the missing dimension. Use the scale factor 1 : 12.
Answers
Answer:
3.84m
Step-by-step explanation:
If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.
32cm * 12 = 384cm
1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters
384 * 0.01 = 3.84m

Answer:
x = 5
Step-by-step explanation:
These triangles are similar, so they are in proportion to each other. Because of this we can say [tex]\frac{2.5}{3.5}[/tex] (the lengths of the vertical sides) = [tex]\frac{x}{7}[/tex] (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.

A square playground is covered with pebbles, except for two equal size triangular portions that have grass. How many square feet do the pebbles cover?
7ft
14ft
Answers
Answer:28\2
Step-by-step explanation:
7+7=14
7+7=14
14+14=28
Triangle A=1\2bh
So 28\2
The pebbles cover an area of 147 sq ft. We can use the Pythagorean theorem to find the solution.
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Now, Let's call the length of the third side of the triangle "x".
Since the two triangles are equal in size, and they share two sides with the square, we can use the Pythagorean theorem to find x.
a² + b² = c²
7² + 7² = c²
49 + 49 = c²
98 = c²
c = √(98)
c = 7 √(2)
So, each triangle has a base of 7 ft and a height of 7 √(2) ft.
And, Area of each triangle = (base × height) / 2
= (7 × 7√(2)) / 2
= 24.5 ft²
Since, there are two triangles,
Hence, the total area of the grass is,
⇒ 24.5 sq ft × 2 = 49 sq ft
Hence, The square has an area of,
⇒ 14ft × 14ft = 196 sq ft
So, The pebbles cover an area of,
⇒ 196 sq ft - 49 sq ft = 147 sq ft.

How many sides does a polygon have if the sum of the interior angles is 900∘?
Answers
Answer:
7 slides
Step-by-step explanation:
Sum of exterior angles of any polygon is always 360∘, it can never be 900∘. Hence, there cannot be any polygon like this.
It appears that by error the word "exterior" has been mentioned. In case sum of interior angles is 900∘,
total sum of all the angles is 900∘+360∘=1260∘.
But sum of each pair of interior and exterior angles add up to 180∘
we have 1260∘180∘=7 such pairs
and hence polygon has 7 sides.
Answer:
It's a heptagon, so 7 sides

Fill out the table as we did in class for the following:
a) y= 3x + 1
b) y= 2x - 5
c) y = - 2x - 2
All between the values of - 3< x < 3
Answers
Answer:
Step-by-step explanation:
Construct a 2-columned table for each function. Arbitrarily choose x values to go into the first column, values between -3 and +3:
Example, for y = 3x + 1:
x y = 3x + 1 (x, y)
--------------------------------
-2 3(-2) + 1 (-2, -5)
0 3(0) + 1 (0, 1)
1
2
x is the "independent variable." You choose the values, subject to the requirement that -3 < x < +3. The function will return the y values, which are dependent upon the inputs x. This will give you a good number (e. g., 5) points to plot. Draw a line through these points to obtain a graph of
y = 3x + 1. And so on. You need to go through this procedure once for each of the 3 given functions.

A farmer has 500 acres of arable land on which he wants to plant potatoes and corn. The farmer has $40,000 available for planting and $30,000 for fertilizer. Planting 1 acre of potatoes costs $90, and planting 1 acre of corn costs $50. Fertilizer costs $30 for 1 acre of potatoes and $80 for 1 acre of corn. (a) Find a system of inequalities that describes the number of acres of each crop that the farmer can plant with the available resources. (Let x and y be the numbers of acres of potatoes and corn, respectively.)
Answers
Answer:
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
Step-by-step explanation:
Let x and y be the numbers of acres of potatoes and corn, respectively.
Then according to the given conditions
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
where both x and y equal to or greater than zero and cannot take a value less than zero.
x + y ≤ 500 --- C
gives us an idea that the total arable land is less or equal to 500 acres.
90x+ 50 y ≤ $40,000------ A
tells us that the total cost of planting potatoes and corn is less or equal to $ 40,000
30x+ 80y ≤ $ 30,000------- B
tells us that the total cost of fertilizers for potatoes and corn is less or equal to $ 30,000
In each of these x and y cannot have negative values or less than zero.

Which of the following pairs of functions are inverses of each other?
Answers
Answer:
THE ANSWER IS B
Step-by-step explanation:
IT JUST MAKES SENSE TO CHOOSE B
The option D pairs of functions are inverses of each other.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find the inverse of a function, write the function f(x) as a function of x and then solve for x as a function of f(x).
For option A,
f(x) = 2 + ∛x
To solve for x,
∛x = f(x) - 2
x = (f(x) - 2)³
That is also the inverse So,
g(x) = (x -2)³ "Not correct"
For Option B,
f(x) = x/6 + 8
To solve for x,
x/6 = f(x) -8
x = 6f(x) - 6 *8
That is also the inverse So,
g(x) = 6x - 6 *8 "Not correct"
For Option C,
f(x) = 7/x - 9
To solve for x,
7/x = f(x) +9
x = [tex]\frac{7}{f(x) +9}[/tex]
That is also the inverse So,
g(x) = [tex]\frac{7}{x +9}[/tex] "Not correct"
For Option D,
f(x) = 5x - 11
To solve for x,
5x= f(x) + 11
x = (f(x) + 11)/5
That is also the inverse So,
g(x) =(x + 11)/5 "correct"
Thus, the option D pairs of functions are inverses of each other.
