From her eye, which stands 1.66 meters above the ground, Deondra measures the
angle of elevation to the top of a prominent skyscraper to be 70°. If she is standing at
a horizontal distance of 276 meters from the base of the skyscraper, what is the
height of the skyscraper? Round your answer to the nearest tenth of a meter if
necessary.
Answer:
760 m
Step-by-step explanation:
You can draw a right triangle.
For the angle of 70°, 276 m is the adjacent side.
The heigh of the building above 1.66 m is the opposite side.
tan x = opp/adj
tan 70° = h/276
h = tan 70° × 276
h = 758.3
h is the height above 1.66 m.
height = 758.3 m + 1.66 m = 759.96 m
Answer: 760 m
Find the value of x. Round to the nearest tenth
Answer:
x is approximately 13.7
Step-by-step explanation:
tan(58°) = 22/x
x tan(58°) = 22
x = 13.7
what is the solution set of 2/5 (x+4) -3/5 (2x+3) = 2/5(2-x)-1
Step-by-step explanation:
2/5(x+4) - 3/5(2x+3) = 2/5(2-x)-1
2/5(x+4)-3/5(2x+3) = 2/5x-1/1(2-x)
2/5(x+4)-3/5(2x+3) = -2/5(2-x)
2/5x+8/5 - 6x/5 + 9/5 = -4/5 - (-2x/5) (-x- = +)
2x/5 + 8/5 - 6x/5 + 9/5 = -4/5 + 2x/5
(take like terms)
2x/5 - 6x/5 - 2x/5 = -4/5 - 9/5 - 8/5
( Find their L.C.M ) (5 is the LCM)
2x - 6x -2x / 5 = -4 - 9 - 8 / 5
-10x / 5 = -13 / 5
( cross multiply)
-50x = -65
x = -65/50
x = -1.3 ( decimal)
or x = 13/10 (improper fraction)
or x = 1 ³/10 ( mixed fraction).
Hope this helps.
Good luck.

8 less than the product of 6 and a number, x
A. 8 - 6x
B.6x-8
C.(6+x)-8
D.8-(6+x)
Answer:
B
Step-by-step explanation:
The number is x and you want 6 of that, so that makes 6x
You want 8 less of this, so subtract 8
Therefore you get 6x - 8
Answer:
B
Step-by-step explanation:
8 less than the product of 6 and x gives the expression 6x-8.

SOMEONE HELP ME! MATH
Answer:
50%
Step-by-step explanation:
The end goal here is to find the total area of the entire figure from the center to the outer radius D. Then take the ratio of region B with respect to the total area, which will give you the probability of landing in the area B.
Circle A has a radius of 4. Circle B has a radius of 8. Circle C has a radius of 12. Circle D has a radius of 16. Therefore, the total area of the dartboard is given by:
[tex]A_{total}=\pi r^2=\pi (16)^2=256\pi[/tex]
The area of the region B can be found by thinking of region B as a shaded region between two concentric circles A and C. The area of the circle C is given by:
[tex]A_C=\pi r^2=\pi (12)^2=144\pi[/tex]
The area of circle A is given by:
[tex]A_A=\pi r^2=\pi (4)^2=16\pi[/tex]
Therefore the area of region B would be:
[tex]A_B=144\pi -16\pi =128\pi[/tex]
Finally, the probability of landing in region B would be:
[tex]P=A_B/A_{total}=128\pi /256\pi =0.5[/tex]

What’s the percentile rank of a score of 64?
Answer: 64%
Step-by-step explanation:
The score you have entered means that the individual who took the test is at the sixty-fourth percentile – their percentile rank is 64%. This means that the student had a test score greater than or equal to 64% of the reference population. Conversely, 36% of students scored equal to or higher than the individual tested.
A company uses 1/4 of a barrel of chocolate chips to make each batch of granola bars. In one day, the company uses 3 1/2 barrels of chocolate chips to make granola bars. How many batches of granola bars did the company make in the day? Can anyone show me the method.
Answer:
14 times.
Step-by-step explanation:
It is how many times 1/4 go in 3 1/2.
3 1/2 as an improper fraction is 7/2.
To make them have the same denominator, we have to change 7/2.
7 x 2 = 14
2 x 2 = 4
So, how many times does 1/4 go in 14/4?
14 times.
The average attendance at school for 5 days was 264. If the attendance on the 5th day was 256, calculate the average attendance for the first 4 day’s
Answer:
266
Step-by-step explanation:
Let the attendence of 5days be a,b,c,d,e
given,
(a+b+c+d+e)/5=264
a+b+c+d+256=264*5 [since 5th day=256]
(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]
average attendence of 4 days =266
simplify 1/6^3 divided by 1/36
Answer:
1/6
Step-by-step explanation:
To simplify the expression:
1. Change the divisor into it's reciprocal
2. Change the sign into a multiplication sign.
3. Evaluate the product of those fractions.
4. Simplify the fraction. (If possible)
Given expression:
[tex]\dfrac{1}{6^3 } \div \dfrac{1}{36}[/tex]
According to step 1, we need to convert the divisor of the expression into it's reciprocal.
[tex]\dfrac{1}{6^3 } \div \dfrac{36}{1}[/tex]
According to step 2, we need to change the division sign (÷) into a multiplication sign (×).
[tex]\implies \dfrac{1}{6^3 } \times \dfrac{36}{1}[/tex]
According to step 3, we need to determine the product of these fractions. This can be done by evaluating the exponent.
[tex]\implies \dfrac{1}{(6)(6)(6) } \times \dfrac{36}{1}[/tex]
[tex]\implies \dfrac{1}{216 } \times \dfrac{36}{1}[/tex]
Multiply the fractions as needed. [a/b × c/d = (a × c)/(b × d) = (ac)/(bd):
[tex]\implies \dfrac{36}{216 }[/tex]
According to step 4, (If possible), Simplify the product of 1/216 and 36. In this case, the product of 1/216 and 36 is 36/216. Since both are divisible by 6, we can divide the numerator and the denominator by 6 to simplify the fraction.
[tex]\implies \dfrac{36 \div 6}{216 \div 6 }[/tex]
[tex]\implies \dfrac{1}{6 }[/tex]
Therefore, the quotient of 1/6^3 and 1/36 is 1/6.

Problem 2 Six different jobs need to be done today at the restaurant where you work. You have a pool of nine available workers. If you can assign only one worker to each job and no more than one job to a worker, how many different worker/job assignments are possible
========================================================
Explanation:
The order matters because the jobs are different. This means we'll use a permutation.
We have n = 9 workers to pick from and r = 6 jobs to fill.
Plug those values into the nPr permutation formula.
[tex]n P r = \frac{n!}{ (n-r)! }\\\\9 P 6 = \frac{9!}{ (9-6)! }\\\\9 P 6 = \frac{9!}{ 3! }\\\\9 P 6 = \frac{9*8*7*6*5*4*3*2*1}{ 3*2*1 }\\\\9 P 6 = 9*8*7*6*5*4 \ \ \text{.... Note: The 3*2*1 cancels}\\\\9 P 6 = 60480\\\\[/tex]
There are 60480 ways to assign the 9 workers to the 6 different jobs where order matters.
----------------------
Another approach:
Label the 6 jobs as A,B,C,D,E,F
For job A, we have 9 workers to pick from.
For job B, we have 8 workers to pick from. This is because it states that there is "no more than one job to a worker".
For job C, we have 7 workers to pick from. And so on. We have this countdown going on. We stop once we reach job F.
We end up with 9*8*7*6*5*4 = 60480 different permutations
The string "9*8*7*6*5*4" is found in the second to last step of the section above.

A cylindrical tank is having water pumped in at a
rate of 45 liters/minute and is releasing water at
the bottom at a rate of 25 liters/minute. After five
minutes, what is the net change in the volume of
the water in the tank in liters?
The net change in the volume of the water in the tank in liters would be 100 liters.
How to find the change in volume?We can calculate the released in released with the released between the water released from the water released .
Quantity of water pumped in per minute = 45 liters
Quantity of water released per minute = 25 liters
Number of minutes = 5 minutes
Total water pumped in = 45 liters × 5 minutes
= 225 liters
Total water released = 25 liters × 5 minutes
= 125 liters
Net change in the volume of the water in the tank in liters
= Total water pumped in - Total water released
= 225 liters - 125 liters
= 100 liters

Answer:
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
Step-by-step explanation:
ok so your computer is
saying:
x^2 + 5x = 2
and takes the 5 divides it by 2 and squares the result
x^2 + 5x + 25/4 = 2 + 25 /4 but then replaces a trinomial with a binomial
(x + 5/2)^2 = 2 + 25/4 = 33/4
solving
x = -5/2 + root(33/4) or x = -5/2 - root(33/4)
or
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
