A right cylinder has a height of 8 inches and a volume of 100 cubic inches. Which measurement is closest to the radius, in inches, of the cylinder? B. C. 16 D. 50
Answer:
A
Step-by-step explanation:
volume of a cylinder:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
We are given the volume (V) and the height (h) and we need to find the radius (r).
To find the radius we are going to want to plug in the given values into the formula for volume of a cylinder and solve for r
so, * plug in given values *
[tex]400= \pi r^28[/tex]
Now we solve for r
step 1 take the square root of each side
[tex]\sqrt{400} =20\\\sqrt{\pi r^28} =\sqrt{\pi } 4*r\\[/tex]
now we have [tex]20=\sqrt{\pi } 4*r[/tex]
step 2 divide each side by sqrt (π) 4
[tex]\frac{20}{\sqrt{\pi } 4} =3.989 \\\\\frac{\sqrt{\pi } 4*r}{\sqrt{\pi } 4}=r\\[/tex]
we're left with r = 3.989
Finally we round to the nearest whole number and get that the answer is A.4
Notation and symbols for fractions cannot be introduced too soon .
Answer:
A fraction is a number consisting of one or more equal parts of a unit. It is denoted by the symbol a/b, where a and b≠0 are integers (cf. Integer). The numerator a of a/b denotes the number of parts taken of the unit; this is divided by the number of parts equal to the number appearing as the denominator b.

What is the value of 95 - 10 + +2(141 - 7)?
Answer:
353
Step-by-step explanation:
95 - 10 + 2(141 - 7)
following PEMDAS we will do parenthesis first
95 - 10 + 2(134)
multiplication is next
95 - 10 + 268
addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.
85 + 268
now we are left with addition
85 + 268 = 353
Answer:

Chris has scored the following points in his last five basketball games: 13,10,14,9,6
How many points must he have score in the next game to average 14 points per game?
PLEASE HELP! NO FILES THO! THEY DON'T WORK!
Answer:
he must score 32 points in the next game in order to average 14 points per game.
Step-by-step explanation:
14 x 6 = 84
84-(13+10+14+9+6)=32
checking:
32 + 13 + 10 + 14 + 9 + 6 = 84
84 divided by 6 = 14
Angel has $60 and his sister has $120. Angel saves $7 per week, and his sister saves $5 per week. Which equation and solution represent the number of weeks, w, it will take for the siblings to have the same amount of money?
A. 7w + 60 = 5w + 120; w = 30
B. 60w + 7 = 120w + 5; w = 30
C. Not here
D. 7w - 60 = 5w - 120; w = 30
Answer:
A. 7w + 60 = 5w + 120; w = 30
Step-by-step explanation:
60 + 7x = 120 + 5x7x - 5x = 120 - 602x = 60x = 30A line passes through the point (10, -6) and has a slope of -3/2 write an equation in slope-intercept form for this line
Answer:
y = -3/2x + 9
Step-by-step explanation:
As we already know the slope, we just need to find the y-intercept.
To find the y-intercept, you have to plug the values of x and y into the equation.
y = -3/2x + b
-6 = -3/2(10) +b
-6 = -15 + b
9 = b
The equation is y = -3/2x + 9

Sammy won 40 bouncy balls at the fall festival. Later, she gave two to each of her friends. She has 8 remaining. How many friends did she give the balls to.
Answer:
Sammy would have 16 friends.
Step-by-step explanation:
Let total number of friends be x, each friend gets 2 balls, this can be denoted as 2x balls.
The final relation can be expressed as:
40 (total number) =2x+8 , here 8 is the remainder after distribution.
Now we can solve for x
40=2x+8
40−8=2x
32=2x
x=16
Answer:
16 friends
Step-by-step explanation:
40 balls - 8 remaining = 32 balls in total
32 b in total / 2 balls each = 16 friends

28
Answer:
19.6
Step-by-step explanation:
missing side = a
a² + b² = c²
a² + 20² = 28²
a² + 400 = 784
a² = 384
[tex]\sqrt{a^2} =\sqrt{384}[/tex]
a = 19.59
Rounded to nearest tenth: 19.6
Answer:
34.4
Step-by-step explanation:
Here, we need to do 28·28 + 20·20
Then, we get 1,184 when we do that, then we square, which gives us 34.4

what is the answer to this problem?
.
A = 9
B = 19
.
Explain.
If median are getting from " ( a + b ) ÷ 2 " . So :
.
Find b :
.
(a + b) ÷ 2 = Median
(17 + b) ÷ 2 = 18
17 + b = 18 × 2
17 + b = 36
b = 36 - 17
b = 19
.
In conclusion, the value of b is 19
.
Find a :
[tex] \frac{7 + a + 12 + 15 + 17 + 19 + 20 + 22 + 24 + 25}{10} = 17[/tex]
[tex] \frac{161 + a}{10} = 17 \\ [/tex]
[tex]161 + a = 17 \times 10[/tex]
[tex]161 + a = 170[/tex]
[tex]a = 170 - 161[/tex]
[tex]a = 9[/tex]
.
In conclusion, the value of a is 9

3) 12ac^14/b^3
4) 9ac^7/b^5
Answer:
its c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents
a^4b^8c^2
For the same property 2c^5 becomes 8c^15
now we have
(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3
if we simplify the numbers we can obtain
(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3
If we simplify the parameters we can obtain
12ac^14/b^3
