Te unoccupied volume (V) of the cube is calculated as
V = volume of cube - volume of sphere
= 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )
= 343 - [tex]\frac{4}{3}[/tex] π × 3,5³
= 343 - [tex]\frac{4}{3}[/tex] π × 42.875
= 343 - 179.59438

Solve the equation: 7(x + 8) = 49
Answer:
-1
Step-by-step explanation:
1.)Reorder the terms:
7(8 + x) = 49
(8 * 7 + x * 7) = 49
(56 + 7x) = 49
2.)Solving
56 + 7x = 49
3.)Solving for variable 'x'.
4.)Move all terms containing x to the left, all other terms to the right.
5.)Add '-56' to each side of the equation.
56 + -56 + 7x = 49 + -56
6.)Combine like terms: 56 + -56 = 0
0 + 7x = 49 + -56
7x = 49 + -56
7.)Combine like terms: 49 + -56 = -7
7x = -7
8.)Divide each side by '7'.
x = -1
9.)Simplifying
x = -1

what is a irrational number minus a irrational number?
Answer:
They won't both be rational but that's about it. If one is rational and the other is not then the result is certainly irrational. Subtracting two irrational numbers might produce a rational value but it might also not. Consider: a=1+2–√, b=2–√ and a=3–√, b=2–√.
Step-by-step explanation:
Answer:
Rational number minus irrational number will result in an irrational number respectively : 2 - √3 is an irrational number. And it's consequent results [ Addition ] will also result the same : Aslike : 2 + √3 is also an irrational number. If you dig deep into the question it is similar to the basic odd minus odd or even minus even.

Doug worked out for 256 minutes.
Doug has an enemy named Cathy
Cathy worked out a total of 4 hours and 15 minutes.
Who worked out more? What was the difference in minutes?
Answer:
Step-by-step explanation:
Cathy worked 4 hours.
4 hours = 4 * 60 = 240 minutes
She worked an additional 15 minutes which brings her total up to 255.
Doug worked 1 minute longer than Cathy.
Answer:
a.) Doug worked more. b.)The difference is one minute.
Step-by-step explanation:
CAN BE DONE DIFFERENTLY
Cathy has 4 & 15 minutes, since each hour is 60 minutes we can multiply 60 by 4.
60
x4
240
Now adding the 15 it'll be 255.
DOUG WORKED MORE.
DIFFERENCE IS 1 MINUTE.

4/5 N= 2/3. N = ?
2/15
5/6
1 1/5
1 7/15
Answer:
N = 5/6
Step-by-step explanation:
4/5 N= 2/3. Find N (solve for N).
Isolate N. To do this, multiply both sides of the equation by (5/4):
(5/4)(4/5)N= (5/4)(2/3)
becomes N = 10/12, or N = 5/6.
Luanne and Fiona each made a salt water solution. Luanne mixed 3 cups of salt with every gallon of water. Fiona mixed 2 cups of salt with every 3 gallons water. Which of these statements is true?
Answer:
See Explanation
Step-by-step explanation:
Given
Luanne
[tex]Salt = 3\ cups[/tex]
[tex]Gallon = 1[/tex]
Fiona
[tex]Salt = 2\ cups[/tex]
[tex]Gallon = 3[/tex]
The question is incomplete, as the options are not given.
However, possible comparison that can be made are
(a) The unit amount of salt
(b) Whose solution is more concentrated with salt
(a) The unit amount of salt
To do this, we divide the amount of salt by the number of gallons.
[tex]Unit = \frac{Salt}{Gallon}[/tex]
For Luanne
[tex]Unit = \frac{3}{1}[/tex]
[tex]Unit = 3 cups/gallon[/tex]
For Fiona
[tex]Unit = \frac{2}{3}[/tex]
[tex]Unit = 0.67cups/gallon[/tex]
(b) Whose solution is more concentrated with salt
By comparing the result in (a)
We have:
[tex]Unit = 3 cups/gallon[/tex] --- Luanne
[tex]Unit = 0.67cups/gallon[/tex] --- Fiona
Luanne unit amount implies that there are 3 cups in every gallon of water;
Fiona unit amount implies that there are 0.67 cups in every gallon of water;
[tex]3 >0.67[/tex]
Hence, Luanne solution is more concentrated with salt
Determine the area of a circle whose diameter is 8 in Use 3. 14 for TT Enter your answer in the box. Round to the nearest hundredth, if necessary. A= blank inches squared
Answer:
50.24
Step-by-step explanation:
Area = pi*r^2
r = diameter/2
r = 4
Area = pi*4^2
Area = 3.14*16
Area = 50.24
Answer:
Step-by-step explanation:
The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.
Here, with the circle diameter being 8, we figure the radius to be half that, or 4.
Then the area of this circle is A = (3.14)(4 in)², or
A = 50.24 in²

A kite and its tail total 48 ft in length. the tails is 7 times the length of the body. How long is the kite's tail?
Answer:
42 ft
Step-by-step explanation:
body = x
tail = 7x
x + 7x = 48
8x = 48
Divide both sides by 8
x = 6
Tail
7x = 7(6)
7x = 42

Usted esta tratando de manejar una inversion con un valor actual de $ 10,000 dentro de 10 años al 5% con acumulación anual. ¿ Cuanto necesita invertir?
Answer:
$6,139.1
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
P is the amount invested
A is the amount = $10000
r is the rate = 5%
t is the time = 10years
10000 = P(1+0.05)^10
10000 = P(1.05)^10
10,000 = P(1.6289)
Swap
P(1.6289) = 10,000
P = 10,000/1.6289
P = 6,139.1
Hence I need to invest $6,139.1
Sue and Bill share a 16-ounce box of cereal. By the end of the week, Sue has eaten 5 8 of the box, and Bill has eaten 1 4 of the box of cereal. How many ounces are left in the box?
Answer: 2 ounce
Step-by-step explanation:
Given
16 ounce of the box is shared by Sue and Bill
Sue has eaten [tex]\frac{5}{8}[/tex] of the box
Bill has eaten [tex]\frac{1}{4}[/tex] of the box
total cereal eaten by them is
[tex]\Rightarrow \dfrac{5}{8}+\dfrac{1}{4}=\dfrac{5}{8}+\dfrac{2}{8}\\\\\Rightarrow \dfrac{7}{8}[/tex]
So, they have eaten this much of the box. Amount left in the box is
[tex]\Rightarrow 1-\dfrac{7}{8}\\\\\Rightarrow \dfrac{1}{8}[/tex]
In ounce it is
[tex]\Rightarrow 16\times \dfrac{1}{8}\\\\\Rightarrow 2\ \text{ounce}[/tex]
1. F(-5)=2x+1
2. F(-4)=2x+1
3. F(1)=2x+1
4. F(3)=2x+1
5. F(5)=2x+1
Answer:
1. F(-5) = -9
2. F(-4) = -7
3. F(1) = 3
4. F(3) = 7
5. F(5) = 11
Step-by-step explanation:
For each problem, F(x) is replaced with x.
An example is F(-5) = 2x + 1 (your first question).
To solve this, you replace x with -5.
This creates F(-5) = 2(-5) +1
We just simplify by multiplying -5 by 2 and then adding 1.
-5 times 2 equals -10. -10 plus 1 equals -9.
Your final answer for this example problem would be F(-5) = -9.
This applies to all problems as such -- F(x) where x inside the parentheses replaces all x values in the equation.

A sociedade brasileira de pediatria recomenda limitar o tempo máximo de telas e jogos de videogames a três horas por dia, para adolescentes com idades entrar 11 e 18 anos Este tempo máximo, se usado todos os dias, representa, dos 11 aos 18 anos, um total de horas que equivale a A) 1 ano B) 3 anos C) 6 anos D) 7 anos E) 8 anos
Responder:
A) 1 ano
Explicação passo a passo:
Tempo máximo de tela = 3 horas / dia
Número de anos entre 11 e 18 anos = 8 anos
Vamos calcular o número de tempo de tela em um ano:
Número de dias em um ano = 365
Horas de uso em um ano:
3 horas / dia * 365 dias = 1.095 horas
Horas de uso em 8 anos:
1.095 horas * 8 = 8.760 horas
Convertendo o número de horas em anos:
Número de horas em um ano:
24 horas * 365 dias = 8760 horas por ano
Anos de tempo na tela:
Número de horas em 8 anos / número de horas em um ano
8760/8760 = 1 ano
√(4²×49)
