Answer:
1.04 inch
Step-by-step explanation:
Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.
Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula:
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope= (∵ Round to two decimal)
∴ Slope of stairways is 1.04.
Answer:
11375
Step-by-step explanation:
From the table :
Proportion of people who bought program :
Total number of items bought = (68 + 19 + 22 + 91) = 200
Number of programs = 91
Proportion of programs = 91 / 200 = 0.455
Of 25000 attendees ; expectd number of program sale :
0.455 * 25000 = 11375
The angle opposite the side measuring 11 inches has one solution of approximately 43°. Thus, the correct option is B.
<h3>What is Sine rule?</h3>
The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
Using the sine rule, the measurement of the angle of opposite the side measuring 11 inches can be done. Therefore, the measure can be written as,
8/ Sin(30°) = 11/ Sin(θ)
Sin(θ) = [11 × Sin(30°)]/8
Sin(θ) = 0.6875
θ = Sin⁻¹ (0.6875)
θ = 43.4325° ≈ 43°
Hence, The angle opposite the side measuring 11 inches has one solution of approximately 43°. Thus, the correct option is B.

The answer will be 14.
Explanation: subtract 16 and 2 and you will get 14.
Now to check your answer add 2 and 14.
Once you have done that the result should be 16.
So your answer will be 14.
Answer:
So, basically, you can do this:
500,001*14<6,550,000.
This works because there is one person that can have 0 hairs, 1 hair, 2 hair and so on until we reach 500,000 hairs. Then, there has to be a repeat. So, we can do this fourteen times. Then, we can see that there are at least 14 people with a certain amount of hairs.
