A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building
Answer:
The height of the building is of 244.95 feet.
Step-by-step explanation:
We use the Pythagorean Theorem to solve this question.
We have that:
The shadow of 50 feet is one side of the right triangle, while the height h is other side.
The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.
So
[tex]50^2 + h^2 = 250^2[/tex]
[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]
[tex]h = 244.95[/tex]
The height of the building is of 244.95 feet.

1. Which of the following relations is NOT considered a function?
(3,4). (4,5), (6,7), (8,9)
(-3,4), (4,-5). (0,0), (8,9)
(13,14), (13,5). (16,7). (18,13)
(3,90). (4,54). (6,71). (8,90)
Answer:
The relation (13,14), (13,5). (16,7). (18,13) is not considered a function
Step-by-step explanation:
Relations are only considered functions if each x value, which is the first number in each ordered pair or set of parentheses, has only one corresponding y-value, which is the second number in each ordered pair. The third option has two y-values, 14 and 5, for one x-value, 13. This means that it does not satisfy the requirements to be a function and therefore it is not a function.

Answer:
Step-by-step explanation:
a) Volume of small cube box = 8 in³
side³ = 8 = 2³
Side of small box = 2 in
b) Side of larger box = 2 + 6 = 8 in
Volume of larger box = 8*8*8 = 512 in³
c) Number of balls to be shipped in the larger box = Volume of larger box ÷ Volume of smaller box
= 512 ÷ 8
= 64 golf balls
solve the equation 4(c-3)-8
what are two ways two start solving this equation? choose both ways.
1.use the distributive property to get 4c-3=8.
2.use the distributive property to get 4c-12=8.
3.add 3 to both sides to get 4c=11.
4.subract 4 from both sides to get c-3=4.
5. divide both sides by 4 to get c-3=2.

The perimeter of a rectangular painting is 280 centimeters. If the length of the painting is 76 centimeters, what is its width?
Answer:
76x2 = 152
280 - 152 = 128
128 ÷ 2 = 64
Answer:
the width is 64cm
Step-by-step explanation:
a rectangle has 4 sides, each set of opposite sides are congruent, perimeter is the distance around an object, so we need to add up all 4 sides and it should equal 280cm, we know one side is 76, so our equation should look as follows:
76 + x + 76 + x = 280
2x + 152 = 280
2x = 128
x=64
you can check the answer but substituting 64 for x and seeing if it comes out to 280
76+64+76+64=280
280=280
Jane has just begun her new job as on the sales force of a very competitive company. In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars. Company policy requires that new members of the sales force must exceed an average of more than $100 per contract during the trial employment period. Can we conclude that Jane has met this requirement at the significance level of 90%
Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100

A total of 584 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
584
Step-by-step explanation:
146 adult tickets were sold.
write out your equation first: x+3x=584
4x=584
x=146
Try it out 146+3(146)=584
It worked. That's the solution.
so lets divide the amount of tickets by 4 because there are 4 parts needed in this situation which equals 146 then we know our answer is 146 because the other three parts go to the kids tickets

The local grocery store has sorted apples by size. The distribution is approximately normal. The large apples have a mean diameter of 10 cm with a standard deviation equal to 0.5 cm. In a bin of 100 large apples, how many can be expected to have a diameter greater than 11.5 cm, three standard deviations above the mean?
Answer:
0
Step-by-step explanation:
Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)
