A furniture store book shelf was priced at
$
345.00
The store was having a
60
%
off sale store wide. What is the sale price of the book shelf?
Answer:
$138.00
Step-by-step explanation:
The original price of the shelf is $345.00. The new sale price is the original price of 100% less the 60% of the original price. That means the sales price is 40% of the original price.
You can do this 2 ways:
1. $345 x 60% or .60 = $207
$345-207 = $138
or
2. $345 x 40% or .40 = $138
Answer:$138
Step-by-step explanation:
Since the store is on sale 60% out of a whole 100%
= 100% - 60% = 40%
40% is [tex]\frac{40}{100}[/tex] = 0.4
0.4 x 345 = $138

Find the volume of the sphere. Round your answer to the nearest tenth.
Answer:
17157.28
Step-by-step explanation:
If we know that the volume of a sphere is equal to V=4/3πr3, then we can assume this.
The radius of the sphere is 16, so 16 cubed is 4096. 4096 x pi is 12867.96
12867.96 x 4/3 is 17157.28
Identify the geometric mean of 8 and 20 in simplest radical form.
Answer:
8/x = x/20
x^2=160
x=sqrt(160)
x=sqrt(16*10)
x=sqrt(16)*sqrt(10)
x=4*sqrt(10)
Step-by-step explanation:
The geometric mean of 8 and 20 in the simplest radical form is 2√10.
What is geometric mean?The Geometric Mean is a unique kind of average in which the numbers are multiplied together and then their square, cube, or other root is taken (for two numbers, three numbers, etc.).
To calculate the geometric mean of two numbers:
You would multiply the numbers together and take the square root of the result.
First, multiply 8 and 20.
That equals 160.
Then you take the square root of 160;
√160
= 12.65,
which doesn't result in a whole number.
So you factor 160 and removing perfect squares.
√160
= √ (4 x 10)
= 2√(10)
Therefore, the geometric mean is 2√10.

keeping in mind that a function does not have any X-Repeats, that is, the 1st coordinate in every pair never repeats, well, in this case, all of them have no X-repeats, that means all of them are functions. However, only one-to-one functions have an inverse that is also a function.
A one-to-one function is one that has no X-repeats as well as no Y-repeats, so each pair in the set has no coordinate repeats, Check the picture below.
For an ordered pairs to represent has an inverse a that is function, It shouldn't show one-to-many relation in the pairs. The answer is {(-4, 3), (-2, 7), (-1, 0), (4, -3), (11, -7)} represents a function.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
The set of all potential values that the function would be return when the domain is provided as input is the definition of range.
The one-to-one function has inverse where the inverse is the function.
That is, should be unique output for each input values.

Answer:
a) V = (8 -4/3π)r³
b) 2048(2 -π/3) cm³ ≈ 1951.34 cm³
Step-by-step explanation:
When a sphere is placed in a box the empty space volume is the difference between the box volume and the sphere volume. Here, the box is a cube with the same outside dimensions as the sphere.
__
a. (formula)The side length of the cube is 2r, where r is the radius of the sphere. So, the volume of the cube is ...
V = s³ = (2r)³ = 8r³
The volume of the sphere is given by the formula ...
V = 4/3πr³
The volume of the empty space is the difference of these:
V = (8r³) -(4/3πr³)
V = (8 -4/3π)r³ . . . . . . . formula for the empty volume
__
b. (empty space)For r=8 cm, the empty volume is ...
V = (8 -4/3π)(8 cm)³ = 4(2 -π/3)(512 cm³)

A farmer has both sheep and chickens on his farm. All the animals have the expected number of parts. When his animals are all
together, there are 90 legs and 32 heads. How many of each animal does he have?
Answer:
13 sheep, 19 chicken
Step-by-step explanation:
You can start to solve this problem by assigning variables. First, let's assign the number of sheep there are as [tex]x[/tex] and the number of chickens there are as [tex]y[/tex].
Because each sheep has 4 legs, the number of legs for each sheep would be [tex]4x[/tex]. Similarly, because each chicken has 2 legs, the number of legs for each chicken would be [tex]2y[/tex]. Each animal would have 1 head, so the number of heads would just be [tex]x[/tex] and [tex]y[/tex]. Because the number of legs in total are 90, [tex]4x + 2y=90[/tex]. Because the number of heads in total are 32, [tex]x+y=32.[/tex]
There is now a system of equations with two unknown variables and two equations. There are many ways to solve this, but for me, the easiest would be elimination. First, I would double the second equation, [tex]2x+2y=64[/tex]. Then, I would subtract that from the first equation, eliminating [tex]y[/tex]. [tex]2x=26[/tex]. Solving for x gives 13. We can then plug that value into the second equation, making y be [tex]32-13=19[/tex]. This means that [tex]x=13[/tex] and [tex]y=19[/tex], meaning that there are 13 sheep and 19 chicken.

A cubical dice is thrown two times, find the probability that the outcomes is 5 in first throw and odd number in second throw.
All the numbers present in cubical dice = 6
( 1 , 2 , 3 , 4 , 5 ,6 ) Total Outcomes = 6Probability = Favorable outcomes / Total number of outcomes
Probability that 5 will come in first throw :-Favorable Outcomes = 1
Favorable Outcomes = 1 Probability = 1/6
Probability that an odd number will come in second throw :-Favorable Outcomes = 3
Probability = 3/6 ; 1/2
In a deck of playing cards, what is the
probability of drawing a red card, replacing it, and
then drawing a queen?
Step-by-step explanation:
As the cards are being drawn with replacement, the events are independent. Thus we can find the probability by multiplying the probability of individual events.
There are 4 queens in a pack of 52 cards. So, probability of drawing a queen= 4/52=1/13
There are 26 red cards. So, probability of drawing a red card= 26/52=12
Required probability= 1/13×1/2=1/26
Answer:
1/26
Step-by-step explanation:
For probability, the numerator is the number of options for the specified property (red card/drawing a queen) and the denominator is the total number of options (in this case 52).
There are 26 red cards in a deck, the the probability of choosing a red card is [tex]\frac{26}{52}[/tex] or [tex]\frac{1}{2}[/tex].
There are 4 queens in a deck, so the probability of choosing a queen is [tex]\frac{4}{52}[/tex] or [tex]\frac{1}{13}[/tex].
To find the probability of getting these both, multiply the results, giving [tex]\frac{1}{26}[/tex].
