Given that :
Height of father's eye above the flat ground :
Kindly check attached picture for diagram:
To obtain the value of h ; we can use Pythagoras rule ;
Tan θ = opposite / Adjacent
Tan 48 = h / 15
15 tan 48 = h
37.126302 = h
h = 37.
Hence, height of father's above the flat ground :
h + 32 = 37 + 32= 69 inches

When checking lightbulbs, a salesclerk found that 15% of the 680 he checked were defective. How many of the lightbulbs were found defective?
Answers
Answer: 102 lightbulbs were found by the detective.
Step-by-step explanation:
Answer:
102 lightbulbs.
Step-by-step explanation:
To get the answer you have to read into the problem this is important on things like this. These are the key words you need to look for, (Checked), (Defective) as well as the percentages and numbers so 15% and 680 are important as well. In the problem is says the "a salesclerk found that 15% of 680 lightbulbs were defective" then it ask "how many lightbulbs were found to be defective" because he said that 15% of the 680 were defective you have to find out what number makes up that 15% of the defective bulbs, In order to do this you 1.) turn 15% into a decimal making it .15
2.) You multiply your decimal by your total which is 680 so it would like this .15 x 680 this would = 120
so your answer is 120.
this is better explanation NOTE THIS IS A EXAMPLE THIS IS NOT THE ANSWER PROBLEM!!!
How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Example: What is 10% of 150?
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15

Answer:
12
Step-by-step explanation:
When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that [tex]\frac{1}{10}[/tex] is bigger than the fraction next to it so in order to find a fraction that is lesser in value than [tex]\frac{1}{10}[/tex], we need to find a denominator that is more than 10, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.

Answers
Answer:
Frazer = x = 10 trees
Sally = y = 7 trees
Frame = z = 14 trees
Step-by-step explanation:
We have 3 friends
They are represented by:
Frazer = x
Sally = y
Frame = z
Total number of trees donated = 31
Rudolph is collecting Christmas trees to donate to needy families. He collects 31 trees He donates all of his trees to 3 of his friends
Frazer gets 3 more trees than Sally
x = y + 3
Sally gets 7 fewer trees than Flame
y = z - 7
z = y + 7
How many trees do each of his friends get?
x + y + z = 31
y + 3 + y + y + 7 = 31
3y + 10 = 31
3y = 31 - 10
3y = 21
y = 21/3
y = 7 trees
x = y + 3
x = 7 + 3
x = 10 trees
z = y + 7
z = 7 + 7 trees
z = 14 trees
Therefore:
Frazer = x = 10 trees
Sally = y = 7 trees
Frame = z = 14 trees

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run? Round your answer to the nearest cm
Answers
Answer:
Chubby ran a distance of 6,283 m
Step-by-step explanation:
The length of one run is simply equal to the circumference of the circle
Mathematically, C = pi * d
C = 22/7 * 20 = 62.83 cm
So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;
62.83 * 100 = 6,283 m

Select the correct answer from each drop-down menu. Graph shows two lines on a coordinate plane. A line labeled p goes through (2, 2) and (0, minus 4). Another line labeled q goes through (0, 2) and (2, minus 4). Both lines intersect at X-axis at 1 and Y-axis at minus 1. The slope of line p is , and the slope of line q is .
Answers
The slope of line p is: 3
The slope of line q is: -3.
How to Find the Slope of a Line?To find the slope (m) of any given line, what we need is the coordinates of any two points on the given line. The formula to apply to find the slope (m) of the line is given as:
Slope (m) = change in y / change in x = y2 - y1 / x2 - x1.
Slope (m) of line p with points (2, 2) and (0, -4):
Slope (m) of line p = -4 - 2 / 0 - 2 = -6/-2
Slope (m) of line p = 3
Slope (m) of line q with points (0, 2) and (2, -4):
Slope (m) of line q = -4 - 2 / 2 - 0 = -6/2
Slope (m) of line q = -3
Therefore, the slope of line p is: 3
The slope of line q is: -3.

What is the value of x in this triangle?
Enter your answer in the box.
Answers
The value of x in the given triangle is 61
From the question, we are to calculate the value of x in the given triangle.
In a given triangle ABC, with interior angles A, B, and C, the sum of the angles is 180°.
That is,
∠A + ∠B + ∠C = 180°
Thus,
In the given triangle,
37° + 82° + x° = 180° (Sum of angles in a triangle)
Solve for x in the in the equation above
37° + 82° + x° = 180°
Add the numbers
119° + x° = 180°=
Subtract 119° form both sides
119° - 119° + x° = 180° - 119°
x° = 61°
Hence, the value of x in the given diagram is 61

The morning announcements said that two out of every seven sixth-grade students in the school have an overdue library book. Jasmine said, “That would mean 24 of us have overdue books!” Grace argued, “No way. That is way too high.”
How can you determine who is right?
Answers
Answer:
We need to know how many students are in sixth grade and compare the real number with the 84 sixth graders that Jasmine claims to be.
Step-by-step explanation:
We would need to know how many students are in sixth grade to determine who is right. If two students out of seven have an overdue library book and grace claims that 24 of them are overdue by that means, what we would need to do is divide the allegedly 24 students between 2. Now we have 12 pairs of students that have overdue books. For every pair of students in sixth grade that have overdue books, seven students don’t have overdue books, so now we multiply 12 pairs of students with overdue books times 7 students who don’t have overdue books. By Jasmine calculation then, sixth grade have 84 students.
If sixth grade have indeed 84 students, Jasmine is right. If there are not 84 students in sixth grade, she is wrong. Grace is right if there are fewer students than 84 in sixth grade.
