Answer:
[tex]\frac{1}{12}[/tex] or 1:12
Step-by-step explanation:
There are 11 teachers : 132 students
Because ratios are just another way of writing fractions, by putting this into a fraction we get:
[tex]\frac{11}{132}[/tex]
Dividing both the numerator and denominator (top and bottom) by 11, we get:
[tex]\frac{1}{12}[/tex]
Thus, the ratio is [tex]\frac{1}{12}[/tex], or 1:12

(1) AÊD
Answer:
Answer:
The answer is 39°
Step-by-step explanation:
BAD = 90°
ADE = 51°
AED = 180° - BAD + ADE = 180° - 90° + 51°
= 39°
39° is the Final answer
#AnswerforTrees
Answer:
39° is the required answer.
Step-by-step explanation:
BAD = 90°
ADE = 51°
AED = 180° - (BAD + ADE)
→ 180° - (90° + 51°)
→ 180° - 141° = 39°

A person is skateboarding to their local skate shop to pick up some sick rims. They skate at 8 miles per hour. The store is 2.5 miles away. How long will it take them to get to the store in hours?
Answer: 0.3125 hours
Step-by-step explanation:
The formula for time taken to cover a distance is:
= Distance / Speed
Distance = 2.5 miles
Speed = 8 miles per hour
Time taken = 2.5 / 8
= 0.3125 hours
In minutes this is:
= 0.3125 * 60 mins
= 19 mins approx

A yield sign is an equilateral triangle with a side length of 36 inches. What is the height (h) of the sign? Leave your answer in simplest radical form.
Answer:
18[tex]\sqrt{3}[/tex] inches
Step-by-step explanation:
Applying,
Pythagoras theorem,
a²= b²+c²
Where a = hypotenus, b = base of the triangle, c = height.
make c the subject of the equation
c = √(a²-b²)................. Equation 2
From the diagram attached,
Given: a = 36 in, b = (36/2) in = 18 in
Substitute these values into equation 2
c = √(36²-18²)
c = √(1296-324)
c = √(972)
c = √(972)
c = √(324×3)
c = 18[tex]\sqrt{3}[/tex] inches

Answer:
[tex] {4x}^{2} - 49y^{2} [/tex]
Step-by-step explanation:
Use (a - b) (a + b) = a^2 -b^2 to simplify the product.
[tex](2x)^{2} - (7y)^{2} [/tex]
To raise the product to a power, raise each factor to that power:

...an investigation into the eating habits of people in the United Kingdom.
Step-by-step explanation:
Participants enter a research study with unique characteristics that produce different scores from one person to another. For an independent-measures study, these individual differences can cause problems. How can these problems be eliminated or reduced with a repeated-measures study? Check all that apply. In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions. In a repeated-measures study, you eliminate extraneous changes to the individuals in the sample over time. In a repeated-measures study, both samples consist of the same individuals, eliminating systematic differences between the two samples, which bias the results. In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
Answer: In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions.
• In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
Step-by-step explanation:
An independent measures design, is an experimental design whereby the condition of the experiment is such that there are different group of participants. Based on the information given, the problems can be eliminated or reduced with a repeated-measures study through:
• In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions
• In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
Therefore, the correct options are A and D.
One bag of lawn fertilizer can cover approximately 6,000 square feet. Mike's lawn is about 300 square feet. When Mike applies fertilizer to his lawn, he applies it to 2/3 of his lawn only. About how many complete times can Mike fertilize his lawn with one bag of fertilizer?
Answer:
Mike fertilize his lawn with one bag of fertilizer = 19.33 times
Step-by-step explanation:
Given - One bag of lawn fertilizer can cover approximately 6,000 square feet. Mike's lawn is about 300 square feet. When Mike applies fertilizer to his lawn, he applies it to 2/3 of his lawn only.
To find - About how many complete times can Mike fertilize his lawn with one bag of fertilizer?
Solution -
Given that,
1 bag of fertilizer can cover approximately 6,000 square feet.
Now,
Mike's Lawn = 300 square feet
He applied fertilizer to 2/3 of his lawn only.
i.e
He applied fertilizer to (2/3)×300 = 200 square feet of lawn
Now,
Total fertilizer left to cover = 6,000 - 200 = 5800 square feet
Now,
Let x be the times for which he fertilize his lawn fully
SO,
300x = 5,800
⇒3x = 58
⇒x = 19.33
∴ we get
Mike fertilize his lawn with one bag of fertilizer = 19.33 times

Answer:
Choice C: Lauren is faster than Kevin, slower than Jeremy.
Step-by-step explanation:
Ok, so it directly says that Jeremy is going at y=12x, or 12 miles per hour. To find how fast Kevin is riding, take two points of the table and use the slope formula to get the speed(.
Slope Formula: (y2-y1) / (x2-x1)
So lets take the table plots (2, 22) and (4, 33) to do this.
(y2-y1) / (x2-x1)
(33-22) / (4-2)
(11) / (2)
The speed of Kevin is 5.5 miles by hour.
Then, it asks for how fast Lauren is going, saying she is twice as fast as Kevin. Therefore, simply do:
5.5 * 2 = 11 miles per hour
To get the third biker's speed.
Now, with all of the speeds of the bikers, we can now compare them. Here's a listing of their speeds to make things easier to compare:
Jeremy: 12 mph
Kevin: 5.5 mph
Lauren: 11 mph
From this, we can see that Lauren is the second fastest. She is slower than Jeremy but faster than Kevin. Therefore, the correct answer choice is C.

Please help, nobody is helping I need to find surface area
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same
[tex]A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20[/tex]
This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6

A person playing a game of chance has a 0.20 probability of winning. If that person plays the game 20 times and wins half of that number of times, what is the difference between the theoretical probability and the experimental probability of that person winning?
Answer:
Step-by-step explanation:
The theoretical result is 0.2 * 20 = 4
The experimental result is 1/2 * 20 = 10
The difference is 10 - 4 = 6
The probability difference = 6/20 = 0.3
