What is the volume of a hemisphere with a diameter of 51.8 inches rounded to the nearest 10th of a cubic inch?
Answer:
volume of a hemisphere ≈ 36369.5 in³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
= [tex]\frac{4}{3}[/tex]πr³ ÷ 2
=[tex]\frac{2}{3}[/tex] πr³
where r is the radius
from the question given, diameter = 51.8 inches
but diameter = 2r , this implies that r = [tex]\frac{d}{2}[/tex] hence r = [tex]\frac{51.8}{2}[/tex] = 25.9 inches
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
volume of a hemisphere =[tex]\frac{2}{3}[/tex] πr³
=[tex]\frac{2}{3}[/tex] × 3.14 ×25.9³
=[tex]\frac{2}{3}[/tex] × 3.14×17373.979
≈36369.5 in³ to the nearest tenth cubic inch.
volume of a hemisphere ≈ 36369.5 in³

Answer:
n =7
Step-by-step explanation:
(n+1) +1 + (n-1) = value first row
3+ (2n-9) +n = value second row
The value has to be the same
Set the equations equal
(n+1) +1 + (n-1) =3+ (2n-9) +n
Combine like terms
2n+1 = 3n-6
Subtract 2n from each side
2n+1-1 -2n = 3n-6-2n
1 = n-6
Add 6 to each side
1+6 = n-6+6
7 = n
Answer:
n =7

Find the volume of the triangular prism described below.
The base is a 45°-45°-90° triangle with a leg of 4 in. The height is 1.7 in.
A 45-45-90 triangle has two legs that are the same length. So both legs are 4 in.
Area of the triangle = 1/2 x 4x4 = 8 square in.
Volume = 8 x 1.7 = 13.6 cubic inches.
Ethane (C2H6) is one of many compounds that burns in oxygen to form carbon dioxide and water, as represented by the equation.
2C2H6 + 7O2 → 4CO2 + 6H2O
Which substance is a product in this reaction?
carbon (C)
oxygen (O2)
water (H2O)
ethane (C2H6)
Answer:
Water (H2O)
Step-by-step explanation:
When hydrocarbons undergo combustion reactions (I.e reactions with oxygen) carbon (iv) oxide and water are usually produced.
In this case, the only difference is the numbe of moles between the product and reactant
Equation of reaction;
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Reactants:
1. Ethane = C₂H₆
2. Oxygen = O₂
Product:
1. Carbon(iv) oxide = CO₂
2. Water = H₂O
Answer:
H20

Answer: Isosceles
Step-by-step explanation:
Given: AB || DE , BC is a transversal
∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°
∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°
By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°
Triangle is isosceles because ∠A ≅ ∠C

x^2 + 3x – 4 = 0
Answer:
x = -4, x = 1
Step-by-step explanation:
x^2 + 3x - 4 = 0
4 and -1 add to 3 and multiply to -4.
(x+4)(x-1) = 0
Separate these by the Zero Product Property.
x+4 = 0
x-1 = 0
Solve.
x = -4
x = 1
An equation is given.
A=4π r^2
Solve the equation for r .
A) r=4πA/2
B) r=A/2π
C) r=√A/4π
D) r=√4π/A
Answer:
Hello There. The correct answer to this is B. Because it shows that A = 4pr2 We need divide each term of 4pr2 = A r2 A-4p Then we need to do is Take the square root of both sides of the equation to eliminate the exponent on the left side. r = + A-4p Then completed of the solution is the result of both the positive and negative portions of the solution.

A standard television has a width-to-height aspect ratio of 4:3. How many cm is the
diagonal of a standard television screen that is 49.8 cm tall?
Answer:
Diagonal of television = 83 cm
Step-by-step explanation:
Width of television = 4x
height of television = 3x
Height of television = 49.8 cm
[tex] \therefore \: 3x = 49.8 \\ x = \frac{49.8}{3} \\ x = 16.6 \: cm \\ 4x = 4 \times 16.6 = 66.4 \: cm \\ \\ diagonal \: of \: television \\ = \sqrt{ {(66.4)}^{2} + (49.8)^{2} } \\ = \sqrt{ 4,408.96 + 2,480.04 } \\ = \sqrt{6,889} \\ = 83 \: cm \\ [/tex]

Answer:
66
Step-by-step explanation:
Answer:
y=66
Step-by-step explanation:
Start with the angle that has the purple arrow pointing to it. Next to it, part of the right angle is 27 degrees so you subtract that from 90 degrees, which makes you get 63 degrees. The measurement of all a triangle's angles is 180 degrees, so you add 63 and 51 to get 114, then subtract 114 from 180 to get 66 degrees.
Hope this helps!

What is the probability that a randomly-chosen student from this group did not take exactly two subjects?
Answer:
[tex]\dfrac{118}{135}[/tex]
Step-by-step explanation:
Total Number of Students =135
Number who took all three subjects=5
Number who took PE and BIO=10
Number who took PE and ENG=15
Number who took BIO and ENG=7
Therefore:
Number who took PE and BIO only=10-5=5Number who took PE and ENG only=15-5=10Number who took BIO and ENG only =7 -5=2Total Number of students who took exactly two subjects=5+10+2=17
Therefore:
Number of students who did not take exactly two subjects=135-17=118
The probability that a randomly-chosen student from this group did not take exactly two subjects
[tex]=\dfrac{\text{Number of students who did not take exactly two subjects}}{\text{Total Number of students }} \\=\dfrac{118}{135}[/tex]

Here is a list of numbers:
17,6,-10,-7, -12,-12, -2, 16, -14
State the median.
Put the numbers from least to greatest.
17, 6, -10, -7, -12, -12, -2, 16, -14 → -14, -12, -12, -10, -7, -2, 6, 16, 17
The median is the middle number of a data set.
-14, -12, -12, -10, -7, -2, 6, 16, 17
Therefore, the median is -7.

The teams ratio of games won to games played was 5 to 6 If. The team played 36 games, how many games did the team fail to win
Answer:The team failed to win 6 games.
Step-by-step explanation: 5/6 has to be equal to something over 36. Since you multiplied the denominator by 6 you have to multiply the numerator by 6 and 5*6 equals 30. If out of 36 games they won 30. Then to find how many games they lost all that you have to do is subtract 36 and 30 to get 6.

The quadrilaterals are similar.
If CB = 6, GF = 3, and CD = 4, find GH.
A) 2
B) 3
C) 8
D) 10
Answer:
a
Step-by-step explanation:
CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD
The solution is, the value of GH = 2, option A.
What is scale factor?A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.
here, we have,
If CB = 6, GF = 3, and CD = 4,
and, we have to find GH.
from the given figures we get,
CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD.
i.e. CB/GF = 6/3 = 2
scale factor = 2.
again, CD/GH = 2
So, GH = CD/2
=2
Hence, The solution is, the value of GH = 2.
