Answer:
-13/5
Step-by-step explanation:
-4/5 x 7= -28/5
3=15/5
-28/5 + 15/5= -13/5
The height of the building is 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- Angle of elevation = 4. 72 degrees
- hypotenuse side = 36 feet tall
- Building height is the opposite side
Using the sine identity:
sin θ = opposite/hypotenuse
Substitute the values
sin 4. 72 = x/ 36
cross multiply
x = sin 4. 72 × 36
x = 0. 0822 × 36
x = 3 feet
Thus, the height of the building is 3 feet

Answer:
5
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
First find the median.
The median is the middle value of the data set arranged in ascending order
1 5 5 7 9 ← data in ascending order
↑ median
The lower quartile is the middle value of the data to the left of the median. If there is not an exact middle then it the average of the values on either side of the middle.
1 5
↑ lower quartile = = 3
The upper quartile is the middle value of the data to the right of the median.
7 9
↑ upper quartile = = 8
Thus
interquartile range = 8 - 3 = 5
Answer:
14x + 5 = 31
x= 13/7
2x - 3y = -29
=2x - 3y +29 =0
Step-by-step explanation:
14x + 5 = 31
first step move the +5 to the other side beside the 31 it will become -5
Then subtract the numbers 31-5 =26
14x=26
Divide both sides by 14
x= 13/7
