141300/300 = 471The angle of elevation of the top of a tower from two points 121 m and 144 m away from the foot of the tower on th same side are found to be complementary. find the height of the tower.
Answer:
132 m
Step-by-step explanation:
Refer to attachment for figure.
In smaller triangle with angle theta , we have ,
⇒ tanθ = p/b
⇒ tanθ = h/121m
⇒ tanθ = h/121 m
In triangle with angle 90-∅
⇒ tan(90-θ) = p/b
⇒ cot θ = h/144 m
Multiplying these two ,
=> tanθ . cotθ = h/121 m × h/144m
=> 1 = h²/ (121 m × 144m )
=> h² = 121m × 144m
=> h= √ ( 121m × 144m)
=> h = 11m × 12m
=> h = 132 m

Use the following data to construct a frequency table and calculate the mean, mode, and median.
Answer:
A measure of average is a value that is typical for a set of figures. Finding the average helps you to draw conclusions from data. The main types are mean, median and mode. Data is also often grouped.
Step-by-step explanation:
To find the mean add all the ages together and divide by the total number of children.
If you type all those ages into a calculator it is easy to make an error.

The radius of a circle is 18 in. Find its circumference in terms of T.
Answer:
36πStep-by-step explanation:
NOTE : I am assuming that T means π.
The formula for circumference is 2πr, so 2*r = 2*18 = 36.
Since we are leaving it in terms of π, the answer is 36π

IMPORTANT::: Write the #? Next to the answer.
Like for example there’s question #1,
Answer: #1 : .........e.t.c.
Then you write the answer.
Hope you get it!
Answer:
Below.
Step-by-step explanation:
One standard form of the equation of a straight line is
y = mx + c where m = the slope and c = the y-intercept.
Comparing this with y = 3x - 6 we see that:
The slope = 3 and the y-intercept is -6.
The error was in the y-intercept.
#2.
The error is in stating the intercepts
x - intercept is (8, 0) and y-intercept = (0, 2), (NOT (8, 2)).
#3.
The error is in stating the intercepts
x - intercept is (5, 0 and y-intercept = (0, 2).
How do I solve this arithmetic sequence?
Answer:
The 6ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 13
Common Difference = (d) = 4
Now, For 6ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₆ = 13 + (6 - 1) × 4
a₆ = 13 + 5 × 4
a₆ = 13 + 20
a₆ = 33
Thus, The 6ᵗʰ term of this sequence is 33

Plot the value(s) on the number line where this function is equal to zero:
f(x) = (x + 5)(x − 1).
Step-by-step explanation:
if f(x)=0
then
(x+5)=0 and
(x-1)=0
solve for x
x=-5 and x=1
those are the two values where the function equals zero

PLEASE HELP!! Find the circumference of circle K. Round your answer to the nearest hundredth. Circumference = ft
Answer:
12.57 ft
Step-by-step explanation:
Since triangle ∆EFH is a right angled triangle,side |EF| can be determined by
Sin© = Opposite side ÷ hypothenus side where © is the given angle in the triangleSin 60 = 2✓3 ÷ |EF||EF| = 2√3 ÷ sin 60|EF| = 2√3 ÷ 0.8660|EF| = 4ftSince Line |EF| is a straight line that passes through the centre of the circle and touch two sides of the circumference,
line |EF| is the diameter of the circle
Circumference = 2πr where r = radiusradius = diameter ÷ 2radius = 4 ÷ 2radius = 2 ftCircumference = 2πr Circumference = 2 × 22/7 × 2Circumference = 12.57 ftCircumference = 12.57 ftWhat is the value of x?
Enter your answer in the box.
Answer:
183
Step-by-step explanation:
982
Answer:
45
Step-by-step explanation:
You can use the degrees to find the answer. A right triangle always adds up to 180 degrees. The right angle is 90 degrees.
X + Angle A + Angle B = 180 degrees.
Substitute.
X + 90 degrees + 45 degrees = 180 degrees.
Add them up.
x + 135 degrees = 180 degrees.
now subtract 135 from both sides.
x = 45
0. The mean of the numbers 4, 3, 3, x is 5
Find x.
A. 20
B. 10
C. 5.
D. 4
Answer:
x = 10.
Step-by-step explanation:
From the definition of the mean:
(4 + 3 + 3 + x) / 4 = 5
4 + 3 + 3 + x = 20
x + 10 = 20
x = 10.

how do you solve 25 and 2/3 when 2/3 is the exponent of 25
Answer:
Step-by-step explanation:
Im not fully sure about what your asking
If you are attempting to search the answer use ^ than parentheses, 25^(2/3)
If you want to know what 25 to the power of 2/3 is, it is 8.549
Answer to comment:
for fractions the numerator will become the square amount and the denominator will become the sqrt so
25^(2/3)= 25^2=625 = cube root of 625
(i dont know how to get the root symbol in on this so image cube root is just 3 then the root symbol)

Select the correct answer. What are the solutions of this quadratic equation?
6x^2 + 6 = 12x + 18
[tex]x = 1 + \sqrt{3} [/tex]
[tex]x = 2 + 2 \sqrt[]{3} [/tex]
[tex]x = 2 + \sqrt{6} [/tex]
[tex]x = - 1 \: and \: x = 3[/tex]
Answer:
x=1+√3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x^2+6=12x+18
Step 1: Subtract 12x+18 from both sides.
6x^2+6−(12x+18)=12x+18−(12x+18)
6x^2−12x−12=0
For this equation: a=6, b=-12, c=-12
6x^2+−12x+−12=0
Step 2: Use quadratic formula with a=6, b=-12, c=-12.
x=−b±√b2−4ac/2a
x=−(−12)±√(−12)2−4(6)(−12)/2(6)
x=12±√432/12
x=1+√3

Francis surveyed a random sample of 70 7070 students at Franklin High School about their favorite season. Of the students surveyed, 18 1818 chose fall as their favorite season. There are 1816 18161816 students at Franklin High School. Based on the data, what is the most reasonable estimate for the number of students at Franklin High School whose favorite season is fall? Choose 1 answer: Choose 1 answer:
Answer:
467
Step-by-step explanation:
Determine the percentage of those sampled whose favourite season is fall
(18/70) x 100 = 25.7%
the sample is representative of the population of students. So, 25.7% of the students would like fall
number of students at Franklin High School whose favourite season is fall = 25.7% x 1816 = 466.7 students
rounding off to the nearest whole number gives 467
Answer:
467

Kendra spends $15 buying fabric to make baby blankets.She can make 4 blankets from one pice of fabric.If she sells the blankets for $10 each٫what is her profit?
Answer:
her profit is $25
Step-by-step explanation:
Given that
She spends $15 for purchasing fabric so that she make the baby blankets
And, she can make 4 blankets from one piece of fabric
Now she sold the blankets for 10 each
So we need to find out the profit
As we know that
Profit = Selling cost - purchasing cost
= (4 × $10) - $15
= 40 - $$5
= $25
hence, her profit is $25
Find the length of side x in simplest radical form with a rational denominator.
Answer:
x=2√5
Step-by-step explanation:
1st method:
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
2nd method:
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
3rd method:
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
