Approximately how much space is in between the two spheres?
A. 61 cm³
B. 113.1cm³
C. 255.5 cm³
D. 766.6 cm³
Answer:
Step-by-step explanation:
reqd. space=difference of volumes=4/3 πR³-4/3πr³=4/3π(R³-r³)
=4/3 π(5³-4³)
=4/3 π(125-64)
=4/3π(61)
≈255.5 cm³
what does 10 with a little 4 on the top mean
Answer:
They are called exponents, they multiply the number itself (the bigger number) so the answer to 10 with a little 2, means 10x10 or "100"
Answer:
Using exponents is a short way of saying “multiply the number by itself.” The little number up above tells you how many times to multiply the number by itself. So 10 2 means 10 x 10, or 100. ... (Each time you have an exponent of 10, the little number up above tells you how many zeros there will be in the answer).
Ian has a bank account that earns interest. The value, V, in dollars, of Ian's account after T years can be modeled by the exponential function V(t)=5000(1.025)t.
Ian claims that the value of his bank account grows by an equal factor each year. To prove his claim, which equation must he show to be true?
a) V(t+1)−V(t)=1.025
b) V(t)−V(t+1)=1.025
c) V(t+1)V(t)=1.025
d) V(t)V(t+1)=1.025
Answer:
the correct answer is a one
The equation i.e. true is Option b) V(t)−V(t+1)=1.025.
Calculation of an equationSince The value, V, in dollars, of Ian's account after T years could be modeled via the exponential function V(t)=5000(1.025)t. So for claiming that the value of the bank account should be grown at the equal factor at each year so fir this, the option b is considered.
Therefore, The equation i.e. true is Option b) V(t)−V(t+1)=1.025.

A theater offered pre-sale tickets two days before a showing. On the first day, 12
adult and 5 children's tickets were purchased for $114.50. On the second day, 24
adult and 8 children's tickets were purchased for $218. Find the price of an adult
ticket and a children's ticket.
Answer:
Adult ticket: $7.25
Children's ticket: $5.50
Step-by-step explanation:
Set up a system of equations where a represents the cost of an adult ticket and c represents the cost of a child's ticket:
12a + 5c = 114.5
24a + 8c = 218
Solve by elimination by multiplying the top equation by -2:
-24a - 10c = -229
24a + 8c = 218
Add them together:
-2c = -11
c = 5.5
Now, plug in 5.5 as c in an equation to find a:
12a + 5c = 114.5
12a +5(5.5) = 114.5
12a + 27.5 = 114.5
12a = 87
a = 7.25
Answer:
Adult Ticket is $7.25 and Child Ticket is $5.50
Step-by-step explanation:
Lets make 2 equations out of the given information.
a = adults
c = children
Equation 1: 12a + 5c = 114.5
Equation 2: 24a + 8c = 218
We can now multiple Equation 1 by 2 so that we are able to eliminate the value of a.
New Equation 1: 24a + 10c = 229
Equation 2: 24a + 8c = 218
Now we can use subtraction and get a new equation: 2c = 11
Then divide and get: c = 5.5
The cost for a child's or "children's" ticket is $5.50 each. We can fill in the value of the childs ticket and get the value of an adult's ticket as $7.25.
Therefore, Children's Ticket costs: $5.50 & Adult's Ticket costs: $7.25

Step-by-step explanation:

m∠AED = 92°
given f(x) = 3/2x - 5 and g(x) = x^2 + 2x solve for g(-2)
Answer:
g(-2) = 0
Step-by-step explanation:
Since it is asking for g(-2), that means that we only have to worry about the equation g(x) = x^2+2x. When it asks for g(-2), that means you replace every "x" that shows up in the equation with -2.
So plugging in -2 for x we get g(-2)=(-2)^2+2(-2). Simplifying we get g(-2)=4+(-4). Now adding we finally get g(-2)=0

term of the sequence 40,50,60, ....
n starts at 1, and n is a positive whole number (1,2,3,...)
======================================================
Explanation:
The sequence is arithmetic with first term 40 and common difference 10. Meaning we add 10 to each term to get the next one.
--------
a1 = 40 = first term
d = 10 = common difference
[tex]a_n = a_1 + d(n-1)\\\\a_n = 40 + 10(n-1)\\\\a_n = 40 + 10n-10\\\\a_n = 10n + 30\\\\[/tex]
is the general nth term of this arithmetic sequence
Plug in n = 1 and you should get [tex]a_1 = 40[/tex]
Plug in n = 2 and you should get [tex]a_2 = 50[/tex]
and so on

If h(x) = -4 x - 10 find h(- 5)
Answer:
We know that h times x equals the expression: -4x-10. We have been given our value of h which is -4. So we if we plug in the values for the variables, our expression would be: -4(-5). Since they are both negative values, the answer is going to be positive. So, -4 times -5 equals 20.

Step-by-step explanation:
The equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-1) ^2 + (y- -4)^2 = 2^2
(x-1) ^2 + (y+4)^2 = 4

10x <= -32
Divide both sides by 10:

Which statement is true about the following system of equations?
3x - 1/2y = 1
x + 2y = 7
Select one:
a. y<x
O b.y=x
O c.y>x
d. can not be determined
Answer:
c. y>x
Step-by-step explanation:
When given a system of equations, one of many methods can be used to solve these types of systems. One of these includes substitution which involves solving for one variable that is included in another equation, and putting that equality in place of the variable.
Here is what I mean by this:
Given that 3x - 1/2y = 1, and x + 2y = 7, you can rearrange the x + 2y = 7 to solve for x by isolating it.
x + 2y = 7 → x = 2y - 2y = 7 - 2y [for an equation, what you do to one side, you must do to the other] → x = 7 - 2y.
Now that we have an expression which is equal to x.
We can directly replace that with the 3x in the other equation by multypling this by 3:
x = 7 - 2y → 3(x) - 1/2y = 1
3(7 - 2y) - 1/2y = 1
Now that we only have y's, we can simply the equation, and solve for y.
21 - 6y - 1/2y = 1
21 -13/2y = 1
(get rid of the constant on the left side by subtracting)
-21 -21
-13/2y = -20
(remove the denominator by Multiplying)
×2 ×2
-13y = -40
÷13 ÷13
(cancel out the coefficient by dividing)
-y = -40/13
(take the opposite of the other side to make y positive)
×-1 ×-1
y = 40/13.
Now that we have y just solve for x since we already have a term of x in the other equation:
y = 40/13 → x + 2y = 7
x + 2(40/13) = 7
x + 80/13 = 7
Then subtract both constants to find x:
x + 80/13 - 80/13 = 7 - 80/13
x = 7 - 80/13
(create like denominators, but Multipy

literally a free 50 points, just need the answer, What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?
Answer:
n = 1/2
Step-by-step explanation:
So the equation is 4/5n - 1/5 = 2/5n.
So, the first thing that we need to do is get the variable on one side.
So, to do that we need to subtract 4/5n on both sides.
Now our equation is -1/5 = -2/5n
Now the last step is to simplify.
To do that, we need to multiply by the reciprocal of 2/5 on both sides.
That leaves us with 1/2 = n
Answer:
n = 2
Step-by-step explanation:
=> [tex]\frac{4}{5n} - \frac{1}{5} = \frac{2}{5n}[/tex]
Combining like terms
=> [tex]\frac{4}{5n } - \frac{2}{5n} = \frac{1}{5}[/tex]
=> [tex]\frac{4-2}{5n} = \frac{1}{5}[/tex]
=> [tex]\frac{2}{5n}= \frac{1}{5}[/tex]
Cross Multiplying
=> 5n = 2*5
=> 5n = 10
Dividing both sides by 5
=> n = 2
Determine if EF || HL
Answer:
EF is not parallel to HL.
Step-by-step explanation:
They are not parallel because angle HLG is not equal to angle EFG. If the two lengths WERE parallel, those two angles would be equal. Angle GHL would be equal to angle GEF, but they are not equal, either.

A bag of marbles contains only yellow, blue and green marbles. There are 4 yellow marbles and 2 blue marbles, and 1/3 of the marbles are green. If a marble is picked out at random, what is the probability it will be blue? Please give an answer ASAP!
Answer:
2/9
Step-by-step explanation:
There are 4 yellow marbles and 2 blue marbles = 6 marbles
This is 2/3 of the marbles since 1/3 are green
2/3 of the total marbles are 6 marbles
2/3 * m = 6
m = 6 * 3/2 = 9
1/3 m = green marbles = 1/3 *9 = 3
4 yellow marbles and 2 blue marbles 3 green marbles = 9 marbles
P ( blue) = blue/total = 2/9
