The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?
Answers
Answer: 18ft
Step-by-step explanation: I took the quiz and got 100%
The height of the tree is 8.3 ft.
To solve this problem, we have to find the angle of elevation from the student.
To do this, we have to assume or bring out a right angle triangle and solve for the.
Given that we have the distance of A to F and the point to F
A to F = 5ftE to F = 6angle ?Trigonometric RatioUsing trigonometric ratio,
We can find the tangent of this angle
[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]
The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees
[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]
Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be
[tex]15 - 5 = 10ft[/tex]
Let's use the tangent of the angle to find the height of the tree.
[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]
From the calculations above, the height of the tree is 8.3 ft.

It's the only one that cannot be simplified. A number that will divide evenly into both the numerator and denominator so it can be reduced, or The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
Answers
Answer:
4.2 miles
Step-by-step explanation:
6 miles/50 minutes = x miles/35 minutes
1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5
2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:
0.6/5 = 4.2 miles/35 minutes
Two equivalent fractions for 2/3
Answers
Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.

The two-way column relative frequency table is,
Weekday Weekend

Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00
What is two-way frequency table?"It is a way to display frequencies for two categorical variables."
"One category is represented by rows and a second category is represented by columns."
Now, We need to find the column relative frequency table.
First we find the total of each column.
Weekday Weekend
Had an ice cream cone 23 45
Did not have an ice - 155 6
cream cone
Total 178 51
Now, divide each element of column by its respective total.
Weekday Weekend
Had an ice cream cone 23/178 45/51
Did not have an ice - 155/178 6/51
cream cone
Total 178/178 51/51
Therefore, the two-way column relative frequency table would be,
Weekday Weekend
Had an ice cream cone 0.29 0.88
Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00

y1 = 50, y = 90
x1 = 2, x = 4
m = (50 - 90)/(2 - 4)
m = -40/-2
m = 20
b is the y intercept = 50
