A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres?
The volume of the larger sphere is _____π cubic inches greater than the volume of the smaller sphere.
Answer:
1332 will be the correct answer...
Step-by-step explanation:
first sphere:2304π
second sphere:972π
2304π - 972π = 1332π
Answer:
Solution given;
for sphere
radius [r]:12inches
another
radius [R]:9inches
Now
difference in volume of sphere:
volume of sphere of having radius [r-R]
=[tex] \frac{4}{3} πr³[/tex]-[tex] \frac{4}{3} πR³[/tex]
=[tex] \frac{4}{3} π[/tex](12³-9³)
= 1332π cubic inches
The volume of the larger sphere is ___1332__π cubic inches greater than the volume of the smaller sphere.

A triangle has angles measuring 25 degrees and 45 degrees. What is the measure of the triangle's third angle
Answer:
110°
Step-by-step explanation:
Let the third angle be x. All the angles in a triangle add up to 180°. From the previous statement, we can write the equation:
25° + 45° + x = 180°
70° + x = 180°
x = 110°

Match the steps to factor a polynomial with four terms by grouping. Use grouping to factor 20a4 - 10a3 + 12a2 - 6a.
Answer:
Step-by-step explanation:
The first two factor as
10a^3 ( 2a - 1)
The second two factor as
6a (2a - 1)
When you put them together, the common factor is 2a - 1
(10a^3 - 6a) (2a - 1) Can you factor any further? Yes. Try taking out 2a out of the first factor
2a(5a^2 - 3) Now what you have is
2a(5a^2 - 3)(2a - 1) Don't go any further.
Answer:
2a(2a - 1)(5a^2 + 3)
Step-by-step explanation:
You can start by grouping the terms into two groups:
20a^4 - 10a^3 and 12a^2 - 6a
Next, you can factor them:
(20a^4 - 10a^3) + (12a^2 - 6a)
10a^3(2a - 1) + 6a(2a -1)
Now, you can factor out the expression 2a - 1 to get:
(2a - 1)(10a^3 + 6a)
In the second factor, the two terms have a GCF of 2a, so you can factor that out:
2a(2a - 1)(5a^2 + 3)

Last year at a certain high school, there were 60 boys on the honor roll and 112 girls on the honor roll. This year, the number of boys on the honor roll increased by 15%, and the number of girls on the honor roll increased by 25%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answer:
21.5%
Step-by-step explanation:
60 and 112 repsectivly
60x(1.15) + 112(1.25)
69 (hehe nice) + 140
so 209 total honour roles compared to 172 last year
209/172 = 1.215116
subtract 1
.215116
multiply by 100

The diagram shows a solid triangular prism. Height 6cm width 4cm length 10cm the prism is made from wood with a density of 0.8 g/cm3 work out the mass of this prism
Answer:
Step-by-step explanation:
The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.
What is the volume of a prism?The volume of a prism is the total space occupied by it.
What is the density of a prism?The density of a prism is the mass occupied by the 1 cubic unit volume of the prism. The formula for the density of a prism is:
Density = Mass/Volume
How do we solve the given question?In the question, we are given a triangular prism of height 6cm, width 4cm, and length 10cm. Its density is given as 0.8 g/cm³.
We first find the volume of the prism.
The volume = Area of triangle*length = ((1/2)*6*4)*10 cm³ = 120 cm³.
Let the mass of the prism be m grams.
We know the density of the prism is given by the formula,
Density = Mass/Volume
or, 0.8 = m/120
or, m = 120*0.8
or, m = 96
∴ The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.

Wait, we are dividing 8 by 3/5?
Point A is at (-1,8) and point B is at (7,3).
What is the midpoint of line segment AB?
Answer:
( 3, 5.5 )
Step-by-step explanation:
Let,
( x1, y1 ) = ( 7, 3 )
Where,
x1 = 7
y1 = 3
Let,
( x2, y2 ) = ( - 1, 8 )
Where,
x2 = - 1
y2 = 8
Formula : -
Midpoint = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Midpoint of AB
= ( - 1 + 7 ) / 2, ( 8 + 3 ) / 2
= 6 / 2, 11 / 2
= ( 3, 11 / 2 )
= ( 3, 5.5 )

This graph shows time and distance traveled for two objects.
Which statement is true?
A. object 2 travels 6/5 of a foot more per minute than Object 1.
B. Object 2 travels 5/6 of a foot more per minute than object 1.
C. Object 1 travels 6/5 of a foot more per minute than object 2.
D. Object 1 travels 5/6 of a foot more per minute than object 2.
Object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.
What is a graph?"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things".
For the given situation,
The graph is plotted between time and distance.
The distance is represented as 'd'
The time is represented as 't'
The speed is represented as 's'
The formula for speed is given as speed = distance/time
Now consider object 1 :
Distance, d = 105 feet
Time, t = 70 minutes
Now consider object 2 :
Distance, d = 70 feet
Time, t = 105 minutes
Take the ratio of their speeds.
[tex]s1:s2 = \frac{105}{70}:\frac{70}{105}[/tex]
⇒ [tex]s1:s2 = \frac{3}{2}:\frac{2}{3}[/tex]
⇒ [tex]s1:s2= \frac{9:4}{5}[/tex]
Hence we can conclude that object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.

AB is parallel to ED.
ACD and BCE are straight lines.
AB = 8 cm
AC = 4.8cm
BC = 6.4cm
ED = 20 cm
Work out the length of BE.
Answer:
BE = 22.4 cm
Step-by-step explanation:
Δ CAB and Δ CDE are similar , then ratios of corresponding sides are equal, that is
[tex]\frac{CB}{CE}[/tex] = [tex]\frac{AB}{DE}[/tex] , substitute values
[tex]\frac{6.4}{CE}[/tex] = [tex]\frac{8}{20}[/tex] ( cross- multiply )
8 CE = 128 ( divide both sides by 8 )
CE = 16 cm
Then
BE = BC + CE = 6.4 + 16 = 22.4 cm
