A pole that is 2.7 m tall casts a shadow that is 1.56 m long. At the same time , a nearby building casts a shadow that is 38.25 m long. How tall is the building ? Round your answer to the nearest meter.
Set up a ratio of height/ shadow
2.7/1.56 = x/38.25
Cross multiply:
1.56x = 103.275
Divide both sides by 1.56
X = 66.2
Round to nearest meter = 66
Answer: 66 meters
The base of the pyramid is a regular hexagon. Find the volume of the pyramid. Round your answer to the nearest tenth.
pls pls help answer
Answer:
216.5
Step-by-step explanation:
Pyramid volume=(area of the base)*(height)/3
Pyramid volume=(area of hexagon with side 5)*(height)/3
Area of hexagon is 3*sqrt(3)*(side)^2/2=75*sqrt(3)/2
Pyramid volume=10*(75*sqrt(3))/(2*3)=216.5

y varies is directly as 3x – 4, and y = 33 when x = 5
Find:
a) y when x = 2
b) x when y = 15
Answer:
See explanation
Step-by-step explanation:
y = k * (3x - 5)
Where,
k = constant of proportionality
y = 33 when x = 5
y = k * (3x - 5)
33 = k * (3 * 5 - 5)
33 = k * (15 - 5)
33 = 15k - 5k
33 = 10k
k = 33/10
k = 3.3
a) y when x = 2
y = k * (3x - 5)
y = 3.3(3 * 2 - 5)
= 3.3(6 - 5)
= 3.3(1)
y = 3.3
b) x when y = 15
y = k * (3x - 5)
15 = 3.3(3x - 5)
15 = 9.9x - 16.5
15 + 16.5 = 9.9x
31.5 = 9.9x
x = 31.5/9.9
x = 3.18
Find: (6m5 + 3 – m3 – 4m) – (–m5 + 2m3 – 4m + 6)
Answer: 7m⁵ -3m³ - 3
Working:
= (6m⁵ + 3 - m³ - 4m) -(-m⁵ + 2m³- 4m +6)
= 6m⁵ + 3 - m³ - 4m +m⁵-2m³+4m - 6
= 6m⁵ + m⁵-m³ -2m³ -4m + 4m - 6 +3
= 7m⁵ -3m³ - 3

Find the measure of the indicated angle to the nearest degree.
Answer:
? ≈ 37°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos? = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4}{5}[/tex] , then
? = [tex]cos^{-1}[/tex] ([tex]\frac{4}{5}[/tex] ) ≈ 37° ( to the nearest degree )

Jeremy is making a trail mix containing raisins and peanuts. Raisins cost $1.50 per pound. Peanuts cost $2.50 per pound. Jeremy spends $10.50 to make 5 pounds of trail mix. He uses the table below to organize this information. A Table titled Trail Mix showing Pounds, Cost, and Total. The first row shows Raisins, with r, 150, and 1.5 r. The second row shows Peanuts, with 5 minus r, 2.50, and 2.5 left-parenthesis 5 minus r right parenthesis. The last row shows Mixture, with 5, blank, and 10.50. Which equation can Jeremy use to determine the amount of raisins in the trail mix? r + 1.50 = 1.5r r + (5 – r) = 5 1.5r + 2.5(5 – r) = 10.50 1.5r + 2.5(5 – r) = 5

Polygon ABCDEF has 6 sides. A is 170° C is 133° D is 102° he is 117° and F is 90°. What is the measure of b?
Answer:
[tex]B = 134^o[/tex]
Step-by-step explanation:
[tex]n = 6[/tex] --- sides
[tex]A = 170^o[/tex]
[tex]C = 107^o[/tex]
[tex]D = 102^o[/tex]
[tex]E = 117^o[/tex]
[tex]F = 90^o[/tex]
Required
The measure of B
The interior angles of a polygon is:
[tex]Angles = (n - 2) * 180[/tex]
So, we have:
[tex]Angles = (6 - 2) * 180[/tex]
[tex]Angles = 4 * 180[/tex]
[tex]Angles = 720^o[/tex]
The measure of B is calculated using:
[tex]A + B + C + D + E + F = 720[/tex]
Substitute known values
[tex]107 + B + 170 + 102 + 117 + 90 = 720[/tex]
Collect like terms
[tex]B + 107 + 170 + 102 + 117 + 90 = 720[/tex]
[tex]B + 586 = 720[/tex]
Collect like terms
[tex]B = 720 - 586[/tex]
[tex]B = 134^o[/tex]

Kasonga's TV plan costs $59.99 per month plus $5.49 per first-run movie. How many first-run movies can he watch if he wants to keep his monthly bill to be a maximum of $100?
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation for the monthly bill. First, the cost is $59.99 per month, and that cannot be decreased, so we must add all costs to that amount. Next, it costs $5.49 per first run movie, so for each first run movie, we add $5.49 to the total. Therefore, we can write our equation as
59.99 + 5.49 per first run movie = monthly bill
Representing the number of first run movies as r, we can say
59.99 + 5.49 * r = monthly bill
Next, the monthly bill should be less than or equal to 100, so we can say
monthly bill ≤ 100
59.99 + 5.49 * r = monthly bill ≤ 100
Moreover, we want to maximize r, or the amount of first run movies. Because we add money to the monthly bill for each movie, to maximize r, we have to find the maximum money we can spend on the monthly bill that is still less than or equal to 100. To do this, we set the monthly bill to its maximum limit, or 100, so we have
59.99 + 5.49 * r = 100
subtract 59.99 from both sides to isolate the f and its coefficient
40.01 = 5.49 * r
divide both sides by 5.49 to isolate the variable
r ≈ 7.29
Since we can't buy .29 of a movie, and rounding up to 8 movies would cause us to go past 100 dollars, the maximum movies he can watch if he wants to keep his monthly bill ≤ 100 is 7

Given AB= CD, and mAB = 134 find mCD
Answer:
arc CD = 134°
Step-by-step explanation:
Given 2 equal chords in a circle then the minor arcs are equal, that is
arc CD = arc AB = 134°
The value of mCD is 134°.
What is an arc?The arc is a portion of the circumference of a circle.
Given data as :
chord AB = chord CD, and
mAB = 134°
The minor arcs are equal if there are two similar chords in a circle.
So, arc CD = arc AB
Substitute the value of mAB = 134° in the above equation,
⇒ mCD = 134°
Hence, the value of mCD is 134°.

Step-by-step explanation:
Yes. A translations preserve it's. length, shape,size and orientation. WHY?
, A translation is a rigid transformation so it preserve it physical features of the shape( both pre image and current image).A translation can be used to show if two figures are congruent so it preserve it shape.X =
A)6 2/3
B)9
C)12
I think the answer would be (C) 12 because when you lay the line measuring 5 - 4 flat you can see that it is not covering line x completely. When 3 to the new line of 9 you can see that it fits. Hope this helps!
Find the value of x in the triangle shown below.
Answer:
x ≈ 55.5°
Step-by-step explanation:
Using the Sine rule in the triangle
[tex]\frac{5}{sinx}[/tex] = [tex]\frac{5.7}{sin70}[/tex] ( cross- multiply )
5.7 sinx = 5 sin70° ( divide both sides by 5.7 )
sin x = [tex]\frac{5sin70}{5.7}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{5sin70}{5.7}[/tex] ) ≈ 55.5° ( to the nearest tenth )
Answer:
[tex]x =55[/tex]°
Step-by-step explanation:
An isosceles triangle is a triangle with two congruent sides. One can see that the given triangle is an isosceles triangle, as two sides have a side length of (5) units. One property of an isosceles triangle is the base angles theorem. This theorem states that the angles opposite the congruent sides of an isosceles triangle are congruent. In this situation, this means that two angles have a measure of (x) degrees. As a given, the sum of angles in any triangle is (180) degrees. Thus, one can form an equation, and solve for the unknown, (x):
[tex]x + x + 70 = 180[/tex]
Simplify,
[tex]2x + 70 =180[/tex]
Inverse operations,
[tex]2x + 70 =180[/tex]
[tex]2x = 110[/tex]
[tex]x =55[/tex]

notice how a right triangle was formed, and the Pythagorean theorem could be used to solve this :
a^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a= 8
multiply it by 2 to get the side of the base
