The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?

Answers
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180
Put the following quadratic into vertex
form by completing the square: y = = 4x²
- 3x - 1.
Answers
Step 1: Group the x terms together and factor out the coefficient of the x² term:
y = 4x² - 3x - 1
= 4(x² - (3/4)x) - 1
Step 2: Complete the square by adding and subtracting the square of half the coefficient of the x term inside the parentheses. The square of half of -3/4 is (-3/8)² = 9/64, so we add and subtract 9/64 inside the parentheses:
y = 4(x² - (3/4)x + 9/64 - 9/64) - 1
Step 3: Simplify the expression inside the parentheses by factoring the square trinomial and combining like terms:
y = 4((x - 3/8)² - 9/64) - 1
= 4(x - 3/8)² - 9/16 - 1
= 4(x - 3/8)² - 25/16
Therefore, the quadratic function y = 4x² - 3x - 1 in vertex form is:
y = 4(x - 3/8)² - 25/16
The vertex of the parabola is at the point (3/8, -25/16).

The arc length of the shaded region, given a radius of 4 units and a central angle of 60 degrees, is approximately 4.19 units.
Given:
Radius = 4 units
Angle = 60 degrees
The theory of trigonometry is used in this question to calculate the arc length of a sector.
1. Converting the angle from degrees to radians.
Angle in radians = Angle in degrees × ([tex]\frac{\pi }{180}[/tex])
Angle in radians = 60 × ([tex]\frac{\pi }{180}[/tex])
Angle in radians = [tex]\frac{\pi }{3}[/tex]
2. Calculating the circumference of the circle.
Circumference = 2π × radius
Circumference = 2π × 4
Circumference = 8π units
3. Finding the fraction of the circumference represented by the central angle.
Fraction = Angle in radians / (2π)
Fraction = ([tex]\frac{\pi }{3}[/tex]) / (2π)
Fraction = [tex]\frac{1}{6}[/tex]
4. Calculating the arc length.
Arc Length = Fraction of circumference × Circumference
Arc Length = ([tex]\frac{1}{6}[/tex]) × 8π
Arc Length = ([tex]\frac{8}{6}[/tex])π
Arc Length ≈ 4.19 units (using the approximate value of π as 3.14)
Therefore, the approximate arc length of the shaded region is 4.19 units.

There are two tanks at the aquarium. Tank A and Tank B. Each has two sections. The volume of one section of Tank A is 24 cubic feet. The volume of the other section of Tank A is 96 cubic feet. What is the area of volume, in cubic feet, of Tank A?
Tank B has the same volumes as Tank A. The volume of one section of Tank B is 45 cubic feet. What is the volume, in cubic feet, of the other section of Tank B If the area of Tank A is 2,304?
Answers
The area of volume of Tank A is found by adding the volumes of both sections:
24 + 96 = 120 cubic feet
If the area of Tank A is 2,304, then the volume of Tank B is also 2,304. Since one section of Tank B is 45 cubic feet, we can find the volume of the other section by setting up an equation:
45 + x = 2,304
Subtracting 45 from both sides:
x = 2,259
Therefore, the volume of the other section of Tank B is 2,259 cubic feet.

For problems 5 – 8, find the perimeter of the following figures. (3 points each)
Answers
Answer:
5. 132.8 m
6. 5 7/16 in
7. 5 37/63 yd
8. 27.376 m.
Step-by-step explanation:
5) To find the perimeter of a rectangle, add up all of the sides.
Remember, in a rectangle, opposite sides are congruent.
[tex]17.1 + 49.3 + 17.1 + 49.3 \\= 132.8[/tex]
The perimeter is 132.8 m.
-----------------------------------------------------------------------
6) To find the perimeter of a pentagon, simply add up all of the sides.
[tex]1\frac{1}{8} +1\frac{1}{8} +1\frac{1}{16} +1\frac{1}{16} +1\frac{1}{16} \\\\= 5 \frac{7}{16}[/tex]
The perimeter is 5 7/16 in.
-----------------------------------------------------------------------
7) To find the perimeter of a circle, use this formula: π × d OR π × r × r
π = 22/7
r = 1 1/3
Since we know what each variable equals, we plug it into the formula, then solve from there.
π × r × r ➜ 22/7 × 1 1/3 × 1 1/3 = 5 37/63.
The perimeter is 5 37/63.
-----------------------------------------------------------------------
8) To find the perimeter of a circle, use this formula: π × d OR π × r × r
π = 3.14
d = 8.4
Since we know what each variable equals, we plug it into the formula, then solve from there.
π × d ➜ 3.14 × 8.4
= 26.376
The perimeter is 26.376 m.

Answer:
Median: 0.55
Mean: 0.55
Step-by-step explanation:
Median is the middle number and is found from counting to the middle from the numbers on the edge:
0.2 and 0.9. 0.3 and 0.8. 0.3 and 0.7. 0.4 and 0.7. 0.5 and 0.7. 0.5 and 0.6. 0.5 and 0.6. 0.5 and 0.6. 0.5 and 0.6. 0.5 and 0.6. Since there are no more points and we landed between 0.5 and 0.6, find the middle value of these numbers: 0.55.
Mean is a calculation of the middle number from all the values divided by the number of the points:
(0.2 + (0.3 x 2) + 0.4 + (0.5 x 6) + (0.6 x 5) + (0.7 x 3) + 0.8 + 0.9)/20
(0.2 + 0.6 + 0.4 + 3 + 3 + 2.1 + 0.8 + 0.9)/20
(0.8 + 0.4 + 3 + 3 + 2.1 + 0.8 + 0.9)/20
(1.2 + 3 + 3 + 2.1 + 0.8 + 0.9)/20
(4.2 + 3 + 2.1 + 0.8 + 0.9)/20
(7.2 + 2.1 + 0.8 + 0.9)/20
(9.3 + 0.8 + 0.9)/20

Determine the coordinates of polygon A′B′C′D' if polygon ABCD is rotated 180°.
A′(0, 0), B′(−2, 5), C′(5, 5), D'(3, 0)
A′(0, 0), B′(2, −5), C′(−5, −5), D'(−3, 0)
A′(0, 0), B′(−5, −2), C′(5, −5), D'(3, 0)
A′(0, 0), B′(−5, −2), C′(−5, 5), D'(0, 3)
Answers
Answer: the answer is (D) A′(0, 0), B′(−5, −2), C′(−5, 5), D'(0, 3).
Step-by-step explanation: To rotate the polygon 180°, we need to reflect each point over the line passing through the origin and perpendicular to the x-axis.
The point (0,0) will remain the same as it is the origin and the line of reflection passes through it.
To find the coordinates of B', we reflect the point (5,2) over the line to get (-5,-2), then we translate it 5 units to the left to get (-5+5, -2) = (-2, -5).
To find the coordinates of C', we reflect the point (5,-5) over the line to get (-5,5), then we translate it 5 units to the left to get (-5+5, 5) = (0, 5).
To find the coordinates of D', we reflect the point (0,-3) over the line to get (0,3).
Therefore, the coordinates of A', B', C', and D' are:
A' = (0,0)
B' = (-2,-5)
C' = (0,5)
D' = (0,3)
So the answer is (D) A′(0, 0), B′(−5, −2), C′(−5, 5), D'(0, 3).
