The volume of the sphere is the amount of space in it, and the value closest to the radius is 3.5 cm
How to determine the radius of the sphere?The volume is given as:
V = 179.6
The volume is calculated using:
V = 4/3πr³
So, we have:
4/3πr³ = 179.6
Multiply both sides by 3/4
πr³ = 134/7
Divide both sides by π
r³ = 42.88
Take the cube root of both sides
r = 3.5
Hence, the value closest to the radius is 3.5 cm

Surah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 13 people took the trip. She was able to purchase coach tickets for $240 and first
class tickets for $1180. She used her total budget for airfare for the trip, which was $11,580. How many first class tickets did the buy? How many coach tickets did she buy?
Question 1.number of first class tickets bought -
Answer:
781.54
Step-by-step explanation:
240+1180= 1420
11580-1420 = 10160
10160÷13 ~=~ 781.54

Answer:
9 first class tickets
4 coach tickets
Step-by-step explanation:
Let x = number of first class tickets bought
Let y = number of coach tickets bought
Given:
A total of 13 people took the trip⇒ x + y = 13
Given:
Total cost of first class tickets = $1180Total cost of coach tickets = $240 Total budget = $11,580⇒ 1180x + 240y = 11580
Rewrite first equation to make y the subject:
⇒ y = 13 - x
Substitute this into the second equation and solve for x:
⇒ 240(13 - x) + 1180x = 11580
⇒ 3120 - 240x + 1180x = 11580
⇒ 940x = 8460
⇒ x = 9
Therefore, 9 first class tickets were bought.
To find the number of coach tickets bought, simply substitute the found value of x into equation 1 and solve for y:
⇒ 9 + y = 13
⇒ y = 4
Therefore, 4 coach tickets were bought.

Find the roots of each equation by factoring
Answer:
x = -9, -3
Step-by-step explanation:
[tex] {x }^{2} + 12x + 27 = 0[/tex]
[tex](x + 3)(x + 9) = 0[/tex]
x = -3, -9
Answer:
-3 and -9
Step-by-step explanation:
Standard quaratic form: a² + bx + c = 0
x² + 12x + 27 = 0
find 2 numbers that multiply to 27 (the c-value), but add to 12(the b-value);
The numbers will be 9 and 3, since;
9 x 3 = 27
9 + 3 = 12
Now we can put these numbers in the standard factor form: (x + p) (x + q);
(x + 9) (x + 3) = 0
Now we can set each part equal to 0 and solve;
x + 9 = 0 => x = -9
x + 3 = 0 => x = -3
So the roots are;
-3 and -9

Answer:
Height = 18 units
Step-by-step explanation:
Given :
Volume= 162pi, radius= 3 units
We know,
Volume of Cylinder= Pi * (radius)^2*h
now you can substitute, (P.S: dont put the value of pi as it will get cancelled)
162 pi = pi* (3)^2* h
162= 9h
∴h= 162/9= 18
∴ height is 18 units.

Can you answer number 29 please?
Answer:
a. 90
b. 40
c. 55
d. 6
e. 72
Step-by-step explanation:
a: This is a rectangle so all the full corners are 90 degrees. ABC is a corner angle.
b: 1 and 3 are the congruent angles so 3 has the same measure as 1.
C: 1 is a part of the corner, which adds up to 90 degrees. That means angle 2 and angle 1 should add up to 90. They say m<1= 35, so 90-35=55.
d. In a rectangle, the interesecting lines have the same length. AC is 12, so then DB is 12. However, DE is halfway. Half of 12=6.
e. This one has a few steps. Angle 1 is 36, and angle 2 is the other part to the 90 degree corner. 90-36= 54. That gives us angle 2. We know all angles in a triangle add up to 180 degrees. The angle across from angle 2 in the same triangle is the same value, so that is also 54. To find angle 5, it must add up to 180 degrees. 54+54+x=180, in other words. 54+54=108. 180-108=72.

Answer number 6 pleaseeeee
Answer:
20 peopleStep-by-step explanation:
25% = 1/4 of 100
100 represents 200 people here, that means that if 25 = 1/4 to 100, then it is 1/8 to 200. 25x8=200
If 25% = 50, since 50x4=200 and 1/4 = 25% of 100%.
50... ok......
50 = 25%
Now, because there are 5 parts in 25, let's divide 5 by 50, that is 10. That means that 5 = 10 in that 50. 5% = 10 people
So, if 25-15=10
and then 5% = 10 people
5%+5%=10
10+10=20
That means, that 20 people more liked the movie than disliked it.

Explain how you would find the perimeter of this triangle.
Answer:
15.4
Step-by-step explanation:
[tex]\frac{u}{4}[/tex] = tan51.3° ⇒ u = 4tan51.3° ≈ 5
[tex]\frac{4}{v}[/tex] = cos51.3° ⇒ v = [tex]\frac{4}{cos51.3}[/tex] ≈ 6.4
P ≈ 4 + 5 + 6.4 = 15.4
The perimeter of the triangle is 18.56.
What is the perimeter of triangle?The perimeter of the triangle is addition of all three sides.
Given:
The sides of angle is 4, u and v.
The angle of triangle is 51.3 degree.
For finding the value of u and v.
[tex]tan\theta=\frac{opposite}{Adjacent}[/tex]
tan 51.3 = u/4
1.682 =u/4
u = 6.72
[tex]cos\theta=\frac{adjacent}{hypotenuse}[/tex]
cos 51.3 = 4/v
0.51 = 4/v
v = 7.84
Perimeter = u + v + 4
= 6.72 + 7.84 + 4
= 18.56.
Therefore, the perimeter of this triangle is 18.56.

What is an equation of the line that passes through the points (4, -2) and (2, 3)?
Step-by-step explanation:
For this problem, you'll need two formulas:
Slope: y1 - y2/x1 - x2
Point Slope: y - y1 = m(x - x1)
First thing you need to use is the slope formula.
Plugging in your coordinates gives you:
[tex]\frac{-2-3}{4-2}[/tex] = [tex]\frac{-5}{-2}[/tex]
You can simplify this by getting rid of the negatives since two negatives make a positive.
Now to use the point slope formula.
For this formula, the slope we just found, [tex]\frac{5}{2}[/tex], replaces the m, and for the x1 and y1, you use one of the original points(either (4,-2) or (2,3)).
I'll be using the point (2,3). Now plug everything in:
[tex]y-3=\frac{5}{2} (x-2)[/tex]
First thing you should do is distribute the [tex]\frac{5}{2}[/tex]:
[tex]y-3=\frac{5}{2} x-5[/tex]
Next thing to do is get the y by itself by adding 3 to both sides, which gives you your answer of:
[tex]y=\frac{5}{2} x-2[/tex]
