The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If
necessary, round your answer to the nearest tenth.
Answer:
16.9 m
Step-by-step explanation:
The diagram given that represents this situation is a right triangle.
The height of the building can be found using the pythagorean theorem, a² + b² = c².
Where,
a = 26 m
b = height of the building = h
c = 31 m
Plug in the values into the formula
Thus:
[tex] 26^2 + b^2 = 31^2 [/tex]
[tex] 676 + b^2 = 961 [/tex]
Subtract 676 from each side
[tex] b^2 = 961 - 676 [/tex]
[tex] b^2 = 285 [/tex]
Square both sides
[tex] b = \sqrt{285} [/tex]
[tex] b = 16.9 m [/tex] (nearest tenth)

A long-distance telephone company charges a rate of cents per minute or a -cent minimum charge per completed call, whichever is greater. Find the cost, in cents per minute, for a -minute call.
Answer: 50 cents
Step-by-step explanation:
Company charges 8 cents per call and the call in question is 3 minutes. Cost is;
= 3 * 8
= 24 cents
Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.
50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.
how do you figure out the square root of z^2+8z+16?
Step-by-step explanation:
Hey there!
Given;
[tex] = \sqrt{ {z}^{2} + 8z + 16} [/tex]
Looking through question, we can bring it to perfect square to remove the (√) sqrt.
[tex] \sqrt{( {z)}^{2} + 2.4x + {4}^{2} } [/tex]
We made this to bring it in the form of (a+b)^2. As (a+b)^2 = a^2 + 2.a.b + b^2.
Now, our question looks like similar to the formula.
So, We can write it as:
[tex] \sqrt{( {z + 4)}^{2} } [/tex]
Now, we can cancel (√) and (^2). And we get
= z + 4

What is the slope of the line that passes through the points ( 5 , 6 )and ( 5 , 9 ) ? Write your answer in simplest form.
Answer:
3
Step-by-step explanation:
9-6

6-5
=3/1
simplify
m=3
The slope can be found by finding the rise and run of the line
The slope of the line that passes through the points (5, 6) and (5, 9) is infinite
Reason:
The given points on the line are; (5, 6) and (5, 9)
The slope of the line that passes through the given points = Required
Solution:
The x-values of the given points are equal, therefore, the equation of the line that passes through the given points is x = 5
The slope, m, of the line is infinite because;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]Therefore, for the given points, (5, 6) and (5, 9), we have;
[tex]Slope, \, m =\dfrac{9-6}{5-5} = \dfrac{9}{0} = \infty[/tex]Therefore, the slope of the line that passes through the points (5, 6) and (5, 9) is infinite

What is the value of x? (Screenshot included)
Answer:
190
Step-by-step explanation:
Answer:
98
Step-by-step explanation:
The sum of the angles of a triangle should always add up to 180 degrees.
In this problem, they have given us 2 angle measures of the triangle - 53 degrees and 45 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.
I'm just going to do some simple math:
53 + 45 = 98 (sum of the 2 angles)
180 - 98 = 82 (subtracting 180 by the sum of the 2 angles)
However, we have only found the third angle in the triangle. The variable x is for the angle supplementary to the one we just found. Therefore, we must solve the angle measure of the supplementary angle x by doing 180 - 82 which equals 98.

Solve for the value of x in this equation: 146=2+7x+5x
Answer:
x=12
Step-by-step explanation:
First combine like terms
146=2+12x
Then I like to put it into y=mx+b form.
146=12x+2
Next you subtract 2 from both sides.
146-2=12x+2-2
144=12x
Finally you divide 12 on both sides and in the end you get x=12. Hope this helps.
