Answers
Answer: 121
11^2 = 11 x 11 = 121
Answer:
121
Step-by-step explanation:
To square a number, we have to multiply the number by itself. This means we'll multiply 11 by 11.
11 · 11 = 121

Answer:
y = 25.20 m
Step-by-step explanation:
By applying tangent rule in ΔABC,
tan(25)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{y}{BC}[/tex]
BC = [tex]\frac{y}{\text{tan}(25)}[/tex] --------(1)
Now we apply tangent rule in ΔABD,
tan(15)° = [tex]\frac{y}{BC+CD}[/tex]
tan(15)° = [tex]\frac{y}{BC+40}[/tex]
BC + 40 = [tex]\frac{y}{\text{tan}(15)}[/tex]
BC = [tex]\frac{y}{\text{tan}(15)}[/tex] - 40 -------(2)
From equation (1) and (2),
[tex]\frac{y}{\text{tan}(25)}=\frac{y}{\text{tan}(25)}-40[/tex]
[tex]\frac{y}{\text{tan}(25)}-\frac{y}{\text{tan}(25)}=-40[/tex]
[tex]y[\frac{1}{\text{tan}(25)}-\frac{1}{\text{tan}(25)}]=-40[/tex]
y(2.1445 - 3.7321) = -40
1.5876y = 40
y = 25.1953
y ≈ 25.20 m
Therefore, measure of y is 25.20 m.

A man invests $16800 in a savings plan that pays simple interest at a rate of 5% per annum. Find the time taken for his investment to grow to $19800.
Answers
Answer: 3.57 years
Step-by-step explanation:
Based on the question given, the interest is the difference between the amount and the principal which will be:
= $19800 - $16800
= $3000
The formula for Simple interest is given as:
Interest = Principal × Rate × Time
3000 = 16800 × 5% × Time
3000 = 16800 × 0.05 × Time
3000 = 840 × Time
Time = 3000 / 840
Time = 3.57
The time taken to grow the investment is 3.57 years
A satellite is 24,400 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.
Answers
Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.
AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then
(x + 4000)^2 = (13200)^2 + (4000)^2
x = sqrt(13200^2 + 4000^2) - 4000
= 13793 - 4000
= 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Answers
Answer:

Step-by-step explanation:
I hope that is useful for you :)
The height of the tree with angle of elevation of 53⁰ is 66 ft.
What is Angle of Elevation?The angle of elevation is the angle between the horizontal line of sight and the object.
Here, Let the height of the tree be x ft.
The angle of elevation = 53⁰
Distance from ground = 50 ft.
According to question,
tan 53⁰ = x/50
x = 50 × tan 53⁰
x = 50 X 1.32
x = 66 ft.
Thus, the height of the tree with angle of elevation of 53⁰ is 66 ft.

David drew this diagram of a picture frame he is going to make. Each square represents 1 square inch. What is the area of the picture frame?
Answers
Answer:
64 in²
Step-by-step explanation:
Find the area of the larger rectangle first, and then minus the area of the smaller rectangle.
The length of the larger rectangle
= 9-3 = 6 in
The width of the larger rectangle
= 17-1 = 16 in
The area of the larger rectangle
= 6×16
= 96 in²
The length of the smaller rectangle
= 8-4 = 4 in
The width of the smaller rectangle
= 13-5 = 8 in
The area of the smaller rectangle
= 4×8
= 32 in²
The area of the picture frame
= 96-32
= 64 in²

The probability of getting prime number is 2/7.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Outcome = 4, 5, 6, 6, 7, 8, 9.
Number of outcome = 7.
a) The prime numbers from the outcome are 5 and 7.
So, the probability of getting prime number
= 2/7

Aretha's teacher will choose two students from a class of 10 to prepare a display. Assuming the teacher chooses these students at random,
what is the probability that Aretha will not be chosen?
Answers
Answer:
80% chance she will not be chosen
Step-by-step explanation:
the ratio of students picked would be 2:10 so there would be 8:10 students not chosen that is 80%. 20% chance she would be chosen.
I hope this is correct!
The probability that Aretha will not be chosen is 0.8.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, Aretha's teacher will choose two students from a class of 10 to prepare a display.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Probability of choosing 2students =2/10
Probability of not choosing students = 1-2/10
= 8/10

1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F
Answers
The segment that is false is (2) EF= 1/2EB
The median lines of a triangle always meet at a point.
This means that the line from point C is true (option 4 is true)
The median divides the side lengths of the triangle into equal segments.
However, the centroid at point F do not divide line EB into equal segments
This means that:
The equation EF= 1/2EB is false
Hence, the segment that is false is (2) EF= 1/2EB
