Answer any of the questions you dont have to do all but it would help a lot <3
Answer:
DIY
Step-by-step explanation:
Although I would like to help you, you would have to do this yourself.
All you need to do is:
1. Use a ruler and measure the distance from the first location to the second location. *make sure to use the inch side.
2. Distance times 170. *Your product will be in mi( unit).
1. Determine whether 11, 60, and 61 can be the measures of the sides of a triangle. If so,
classily the triangle as acute, right, or obtuse. Justify your answer.
Answer:
C
Step-by-step explanation:
irst check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = and ( )² = 12
2² + ( )² = 4 + 8 = 12
Thus the triangle is right → C

What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
given that tan45°/sin30°
Since tan45° is 1 and sin30° is 0.5 so
By that 1/0.5 which comes out as 2.

Find the total surface area of this cone, leaving your answer in terms of π
The total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².
What is a cone?A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The total surface area of a cone is given by its curved surface area plus area of its base.
Total surface area = curved surface area + area of base
Total surface area = πrl + πr²
Given that;
Radius r = 5cmSlant height l = 9cmTotal surface area TSA = ?Total surface area = πrl + πr²
Total surface area = ( π × 5cm × 9cm ) + ( π × (5cm)² )
Total surface area = 45πcm² + 25πcm²
Total surface area = 70πcm²
Therefore, the total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².

Answer:
M = 4.33885225095
Step-by-step explanation:
Area of the square ABFE = 10² = 100
M = 100 - (2P + Q)
Let’s calculate 2P + Q :
The area 2P + Q = area ΔABC + area of sector ACE + area of sector BCF
Note :
ΔABC is an equilateral triangle
m∠CBF = m∠CAE = 30°
area ΔABC = (CG × AB)÷2 = (8.660254037844×10)÷2 = 43.30127018922
CG = √(10^2 - 5^2)=8.660254037844 (Pythagorean theorem)
area of sector BCF = area ΔACE = 100π ÷ 12 = (8.333333333333)π
then
Area 2P + Q = area ΔABC + area sector ACE + area sector BCF
= 43.30127018922+(100÷12)π+(100÷12)π
= 43.30127018922+ (8.333333333333)π + (8.333333333333)π
= 95.66114774905
Conclusion:
M = 100 - (2P + Q) = 100-95.66114774905 = 4.33885225095

have a good day
Mai gathers a random sample of 30 students at her school and asks them whether they would be willing to start and end the school day 1 hour later than usual. 27 of the students agree that this would be a good idea. Mai goes to the principal and says, "Exactly 90% of all of the students in the school think it’s a good idea to start and end the school day an hour later than usual!"
What is wrong with this statement?
The statement given by Mai to principal is wrong because of it using the word "exactly" in her statement.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).
So, in this case, Mai did sampling(sample of 30 students was selected) instead of working on entire population (all students of her school).
In her sample, she found that 27 out of 30 students think its a good idea to start and end the school day an hour later than usual.
So, from sample, 90% of those 30 students think it’s a good idea to start and end the school day an hour later than usual.
And yes, we can use this data to approximate or predict about the percentage of students who think it’s a good idea to start and end the school day an hour later than usual.
But we cannot surely say that it will be exactly 90%.
The only statement we can give about the population is:
Almost (or such unsure wordings) 90% of all of the students in the school think it’s a good idea to start and end the school day an hour later than usual!
Thus, the statement given by Mai to principal is wrong because of it using the word "exactly" in her statement.

You work at Dave's Donut Shop. The company has decided to redesign the box it uses to hold one dozen donuts. There are 12 donuts in one dozen. Each donut has a diameter of 3 inches and a height of 1.5 inches. The donuts in the original box stood on their side. You have been asked to design a new box that will allow the donuts to lie flat as shown. What is the circumference, in inches, of a donut?
The company has decided to redesign the box it uses to hold one dozen donuts, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).
What is circumference?The circumference is the distance around the edge of a circle or any circular object. It is calculated using the formula:
C = 2πr
To find the circumference of a donut, we need to first find the diameter. The diameter of each donut is 3 inches, so the radius is 1.5 inches. The circumference can then be found using the formula:
C = 2πr
where C is the circumference and π is approximately 3.14.
Substituting the radius, we get:
C = 2π(1.5) = 3π
Therefore, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

If manny paid $114.03 for the items purchased , then he paid the correct amount .
What is the total cost?
The first step is to determine the total cost of all the items purchased.
Total cost = $32.65 + (3 x $14.89) + $39.99 = $117.02.
Now, determine the cost after the promotional sale: (100 - 10%) x $117.02 = $105.32
