Answer:
Let's Convert yards into inches
Base = 40 yards = 1440 inches
Height = 25 yards = 900 inches
Base (Map)/Base (Actual)
40/1440 = 1 : 36
Height (Map)/Height (Actual)
25/900 = 1 : 36
I hope it helps you!
Step-by-step explanation:
Let's expand our knowledge even more by explaining.
The scale of the height and the width is 1 inch equals 1 yard.
the scale of the area would be 1 square inch equals 1 square yard.
for example:
the area of a triangle is equal to 1/2 * base * height.
the base on the map is 40 inches and the height on the map is 25 inches.
the area on the map is therefore 1/2 * 40 * 25 = 500 square inches.
the base in the real world is 40 yards and the height in the real world is 25 yards.
the area in the real world is therefore equal to 1/2 * 40 * 25 = 500 square yards.
the ratio of the area on the map to the area in the real world is 500 square inches / 500 square yards equals 1 square inch / 1 square yard.
that's 1 square inch to 1 square yard.
in general, if the scale in the linear measurements were a/b, then the scale in area would be (a/b)^2.
since your scale in linear measurements is 1/1, then the scale in area would be (1/1)^2 which is equal to 1/1.
assuming the scale in linear measurements were 1/2, then the scale in area would be (1/2)^2 = 1^2/2^2 = 1/4.

Carmen is a professor at a local university. In collecting data on her Introduction to Business course for a year, she wants to calculate the z-score for a student who scores a 92 on the final exam. The mean and the standard deviation scores on the exam are 76 and 6, respectively. Calculate the z-score.
The z score of a student who scores a 92 on the final exam is 2.67.
Z scoreZ score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where x is the raw score, μ is the mean and σ is the standard deviation
Given that σ = 6, μ = 76. For a raw score of 92:
z = (92 - 76) / 6 = 2.67
The z score of a student who scores a 92 on the final exam is 2.67.

Step-by-step explanation:
A sofa is being sold for $378 this is a 28% discount what is the original price
$378 is 72% of the original price.
72% = $378
1% = $378/72
1% = $5.25
100% = $5.25(100)
100% = $525
The original price of the sofa is $525

What's the answer for 6m^2+18m+17=-3m^2+9
Answer:
m=−2/3 or m=−4/3
Step-by-step explanation:
Step 1: Subtract -3m^2+9 from both sides.
6m^2+18m+17−(−3m^2+9)=−3m^2+9−(−3m^2+9)
9m^2+18m+8=0
Step 2: Factor left side of the equation.
(3m+2)(3m+4)=0
Step 3: Set factors equal to 0.

In planning her retirement, Liza deposits some money at 3.5% interest, with twice as much deposited at 4.5%. Find the amount deposited at each rate if the total annual interest income is $2250.

we also know that whatever "a" amount is, their sum is 2250, thus

A mechanic charges a $30 flat rate plus $20 per hour. If he wants to earn at least $350 this week, how many hours will he need to work?
Answer:
16 hours
Step-by-step explanation:
Let the mechanic works for x hours to make a money of $350.
Fixed charges = $30
Charges per hour = $20
So, charges for x hours = $20x
Total money earned = $350
[tex] \implies \: 20x + 30 = 350 \\ \\ \implies \: 20x = 350 - 30 \\ \\ \implies \: 20x = 320 \\ \\ \implies \: x = \frac{320}{20} \\ \\ \implies \: x = 16 \: hours[/tex]
Thus, the mechanic needs to work for 16 hours to make $350.

Evaluate the expression
cos(30°)=
Answer:
[tex]cos (30) =\sqrt{\frac{3}{2} } =0.8660[/tex]
Step-by-step explanation:
By using the cos square identity in trigonometry i.e., cos2ϴ = 1 – sin2 ϴ, we can evaluate the exact value of cos(33 ). For calculating the exact value of cos(∏/6), we have to substitute the value of sin(30°) in the same formula.
cos(30°) = √1 – sin230°
The value of sin30° is 1/2 (Trigonometric Ratios)
cos(30°) = √1 – (1/2)2
cos(30°) = √1 – (1/4)
cos(30°) = √(1 * 4 – 1)/4
cos(30°) = √(4 – 1)/4
cos(30°) = √3/4
Therefore, cos(30°) = √3/2
Step-by-step explanation:
cos 30° is √3 /2

Lincoln High School has 84 teachers. 12 of the teachers teach math. Of the 32 females teachers, 6 teach math.
What is the probability that a teacher is a woman or teaches math? Express your answer as both a fraction and a percetage.
Probabilities are used to determine the chances of events
The probability that a teacher is a woman or teaches math is 45.24%
How to determine the probabilityThe given parameters are:
Teachers = 84
Math teachers = 12
Female teachers = 32
Female math teachers = 6
The number of female or math teachers is:
Female or math = Math + Female - Female math
So, we have:
Female or math = 12 + 32 - 6
Female or math = 38
The probability that a teacher is a woman or teaches math is:
[tex]Pr = \frac{38}{84}[/tex]
Simplify
[tex]Pr = \frac{19}{42}[/tex]
Express as percentage
[tex]Pr = 45.24\%[/tex]
Hence, the probability that a teacher is a woman or teaches math is 45.24%
