Answer:
1767.15cm^3
Step-by-step explanation:
volume of a sphere is V= 4/3 *pi* r^3
and pi is 22/7 or 3.142
and the value for r is 7.5
therefore v is 4/3 *3.142*7.5^3
v= 1767.15

Find the values of X and Z
Answer:
x = 12, z = 109
Step-by-step explanation:
12x - 73 = 71
12x = 71 + 73 = 144
x = 144/12 = 12
z = 180 - 71 = 109

Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Using the slope concept, it is found that he stepped back 63.44 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
Initially, we have that:
The vertical change is of 85 feet.The horizontal change is his distance d.The angle is of 68º.Hence:
[tex]\tan{68^{\circ}} = \frac{85}{d}[/tex]
[tex]d = \frac{85}{\tan{68^{\circ}}}[/tex]
[tex]d = 34.34[/tex]
When he stepped back, the angle was of 41º, hence:
[tex]\tan{41^{\circ}} = \frac{85}{d}[/tex]
[tex]d = \frac{85}{\tan{41^{\circ}}}[/tex]
[tex]d = 97.78[/tex]
97.78 - 34.34 = 63.44.
Hence he stepped back 63.44 feet.

An angle measures 78° less than the measure of its complementary angle. What is the measure of each angle?
Answer: 6 and 84 degrees
Step-by-step explanation:
Let the measure of the angle = x.
Since complementary angles sum to 90 degrees,
x + (x+ 78) = 90
2x + 78 = 90
2x = 12
x = 6.
Therefore the angles are 6 and 84 degrees.
24 is 3/4 of ___
Find the answer
Answer:
24 is 3/4 of 32.
Step-by-step explanation:
if you understand:
24 divided by 3 (3 in 3/4) is 8.
8 x 3 = 24, so if we need to fill in the extra 1 in 3/4 (making it 4/4), we would need to add another 8. 24 + 8 = 32. (u can look up ' what is 3/4 of 32 too ')

Use a ~ 3.14 and round your answer to the nearest hundredth.
6 m
Answer:
113.1
Step-by-step explanation:
Using the volume (for sphere) formula:
V = (4/3)*pi*(r^3)
You can plug in the radius (diameter/2, the diameter is 6m) to get a volume of 113.1.
Answer:
113.04m³
Step-by-step explanation:
[tex]Solution,\\\\Diameter(d)=6m\\\\Radius(r)=6m/2=3m\\\\Now,\\\\Volume=\frac{4}{3} \pi r^{3} \\\\Volume=\frac{4}{3} *3.14*(3m)^{3} \\\\Volume=113.04m^{3}[/tex]
Are the polygons similar? If they are, write a similarity statement. The figures are not drawn to scale.
Based on the SAS similarity theorem, both triangles are similar.
Similarity statement is: ΔSTV ~ ΔPQR by SAS Similarity Theorem.
What are Similar Polygons?Similar Polygons have different size but the same shape, and as such, the ratio of their corresponding side lengths are equal, while their corresponding angles are congruent.
Based on the SAS similarity theorem, two triangles are similar to each other if they have two pairs of corresponding sides that are proportional and an included pair of angles that are congruent.
In ΔSTV and ΔPQR:
m∠S ≅ m∠P = 86° (one pair of included congruent angles)
ST/PQ = SV/PR = 0.67 (proportional sides).
Therefore, based on the SAS similarity theorem, both triangles are similar.
Similarity statement is: ΔSTV ~ ΔPQR by SAS Similarity Theorem.

How do I solve other problems like this?
y=mx+b
Answer:
y = -2x - 3
Step-by-step explanation:
in the equation y = mx + b,
m = slope b = y-intercept
The y-intercept is provided in the point, (0, -3), because that is where it crosses the y. You're y-intercept is -3
Now you need to find slope. You need to find the difference between these two points to find slope.
[tex]-2+0 = -2[/tex]
[tex]1-3=-2[/tex]
so your slope is going down by 2 and to the left by 2.
Hope this helps! Might be wrong. Try with another example and tell me if it works. <3
Answer: B
Step-by-step explanation:
m is the value of the slope between the two points on the graph
If the two coordinates is (x1,y1) and (x2,y2), the slope is (y1-y2) / (x1-x2)
So the slope for this question is (1-(-3)) / (-2-0) = -2 so the answer is B

(m . n)(7)
A. Undefined
B. 1
C. 0
D. -1
The function value of (m × n)(7) is: C. 0.
How do we Find a Function Value?To find the value of a function, plug in the given value of x and simplify.
Given:
m(x) = x - 7
n(x) = 1/x + 7
Find (m × n)(7)
(m × n)(7) = (x - 7)(1/x + 7)
Plug in x = 7
(m × n)(7) = (7 - 7)(1/7 + 7)
(m × n)(7) = (0)(1/7 + 7)
(m × n)(7) = 0
Therefore, the function value of (m × n)(7) is: C. 0.

A cell phone plan charges $45.50 a month, plus $0.05 per text message. Write and graph an expression to find how many text messages, x, can be sent while still keeping the monthly bill under $60.
Answer:
289 messages
equation: [tex]y=0.05x+45.5[/tex]
graph: attached below
Step-by-step explanation:
We can write this in slope-intercept form, or [tex]y=mx+b[/tex]. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.
Plugging in these numbers, we get [tex]y-0.05x+45.5[/tex]
now we make y = 60, since that is the total amount they have
[tex]60=0.05x+45.5\\14.5=0.05x\\x=290[/tex]
So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
