Answer:
21.27 meters.
Step-by-step explanation:
Please find the attachment.
Let H and h represent height of building and tree respectively.
We have been given that a person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20 m away from the person and the building is 60 m away from the person.
We know that tangent relates opposite side of a right triangle with its adjacent side.
Similarly, we can find height of the tree.
Therefore, the difference in heights between the building and tree is 21.27 meters.
Answer:
2 * 2 * 113
Step-by-step explanation:
452: 2 * 226
226: 2 * 113
113 is a prime number
452: 2 * 2 * 113
452: 2^2 * 113
By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
<h3>What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches?</h3>
According to the empirical rule :
(1) 68% of the measures should come within 1 standard deviation of the mean.
(2 95% of the measures should come within 2 standard deviations of the mean.
(3) 99.7% of the measures should come within 3 standard deviations of the mean.
So we can see in this problem
The mean is 7 inches.
The standard deviation is 1.2 inches.
4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Answer:
(x, y) (2, 7)
Step-by-step explanation:
Choose the correct ordered pair. 2x + 3 = 13
x = 2
Substitute x = 2 into the equation
2(2) + 3
= 4 + 3
= 7
The correct ordered pair is (x, y) (2, 7)
