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?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
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

If you were looking to find the mean of a set of numbers, what would be the correct first step?
a)add the smallest and largest numbers together
b)add all the numbers together
c)subtract the smallest number from the largest number
d)find the number at the midpoint of the set
Answer:
Option B is the correct answer.
Step-by-step explanation:
To find the mean of a set of numbers, you would first add up all of the numbers in that set. Then, you would divide this sum by the number of values that were added up. This would result in the mean.
Example:
Set of Numbers: 10, 5, 15
1.) Add the numbers
10+5+15=30
2.) Divide 30 by the number of values that were added together. Three numbers were added, so you would divide 30 by 3.
30/3=10
The mean of this set would be 10.

Carlos needs an average of 90% or greater on his quiz scores to earn an A in science class for the quarter. Each quiz is worth 20 points. The scores of his first four quizzes are shown in the table. There is one more quiz this quarter.
Quiz Score
1 18
2 19
3 17
4 20
What is the minimum score Carlos can earn on the final quiz to earn at least a 90% average?
Answer: Carlos can score a minimum of 16 points
Step-by-step explanation:
each quiz is worth 20 points, so 20*5= 100 points in total (it is multiplied by 5 because he will be taking 5 tests in total), Carlos has earned a total of 74 points. In order for Carlos to receive a 90% average, he would need a 90/100, so 90-74= 16, therefore, Carlos needs a 16/20 in order to earn a 90% for the quarter.
On solving the provided question we can say that by percentage he need to scores 16 point in each
What is percentage?
A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.
Eden needs an average of = 90%
. Each quiz is worth 20 points
90% 0f 20 = 90/100 * 20 = 16 points
he need to scores 16 point in each
Pls solve and show each step
Option (A) The first theme park had about 5 times as many guests than the second.
Step-by-step explanation:Number of guests in the First Theme Park = 2 * 10^7
= 2 * 10 * 10 * 10 * 10 * 10 * 10 * 10
= 20 * 100 * 100 * 100
= 2000 * 10000
= 20000000
Number of guests in the Second Theme Park = 4 * 10^6
= 4 * 10 * 10 * 10 * 10 * 10 * 10
= 4 * 100 * 100 * 100
= 400 * 10000
= 4000000
Now we can observe that, the number of guests in the First Theme Park is more than the number of guests in the Second Theme Park.
Let’s start dividing to find how many times the First Theme Park has more guests than the Second Theme Park.
Number of guests in the First Theme Park = 20000000
Number of guests in the Second Theme Park = 4000000
Number of times, the First Theme Park has more guests than the Second Theme Park = 20000000/4000000
= 2000000/400000
= 200000/40000
= 20000/4000
= 2000/400
= 200/40
= 20/4
= 5 times

For problems 5 – 8, find the perimeter of the following figures. (3 points each)
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.

Mrs. Smith bought an 8 pound pumpkin so she could make a pie. The pumpkin cost $6.80 How much did the pumpkin cost per pound?
To find the cost per pound of the pumpkin, we need to divide the total cost of the pumpkin by its weight in pounds.
Cost per pound = Total cost / Weight
Cost per pound = $6.80 / 8 pounds
Cost per pound = $0.85
Therefore, the pumpkin cost $0.85 per pound.

question is in the picture
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.

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
