How long will it take a rocket traveling at 8 km/s to reach 20 km? (please include the equation)
Answer:
Step-by-step explanation:
Use the second kinematic formula
[tex]x_f-x_i=V_it+\frac{1}{2}at^2\\20=8t+\frac{1}{2}(9.8)t^2\\4.9t^2+8t-20=0[/tex]
Apply the quadratic formula to solve for time. The negative value does not matter because time cannot be negative, its impossible.
I got a value of t = 1.363 seconds
Can somebody help me please? thank you.

En la tienda de mascotas "Animalo-T", se desea elevar un elefante de 2,900 kg utilizando una elevadora hidráulica de plato grande circular de 75 cm de radio y plato pequeño circular de 13 cm de radio. ¿Calcula cuánta fuerza hay que hacer en el émbolo pequeño para elevar al paquidermo?
Answer:
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
Step-by-step explanation:
Por el Principio de Pascal se conoce que el esfuerzo experimentado por el elefante es igual a la presión ejercida por el plato pequeño. Es decir:
[tex]\frac{F_{1}}{A_{1}} = \frac{F_{2}}{A_{2}}[/tex] (1)
Donde:
[tex]F_{1}[/tex] - Fuerza experimentada por el elefante, medida en newtons.
[tex]F_{2}[/tex] - Fuerza aplicada sobre el plato pequeño, medida en newtons.
[tex]A_{1}[/tex] - Área del plato grande, medida en metros cuadrados.
[tex]A_{2}[/tex] - Área del plato pequeño, medida en metros cuadrados.
La fuerza aplicada sobre el plato pequeño es:
[tex]F_{2} = \left(\frac{A_{2}}{A_{1}} \right)\cdot F_{1}[/tex]
La fuerza experimentada por el elefante es su propio peso. Por otra parte, el área del plato es directamente proporcional al cuadrado de su diámetro. Es decir:
[tex]F_{2} = \left(\frac{D_{2}}{D_{1}} \right)^{2}\cdot m\cdot g[/tex] (2)
Donde:
[tex]D_{1}[/tex] - Diámetro del plato grande, medido en centímetros.
[tex]D_{2}[/tex] - Diámetro del plato pequeño, medido en centímetros.
[tex]m[/tex] - Masa del elefante, medida en kilogramos.
[tex]g[/tex] - Aceleración gravitacional, medida en metros por segundo cuadrado.
Si sabemos que [tex]D_{1} = 0.75\,m[/tex], [tex]D_{2} = 0.13\,m[/tex], [tex]m = 2900\,kg[/tex] y [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], entonces la fuerza a aplicar al émbolo pequeño es:
[tex]F_{2} = \left(\frac{0.13\,m}{0.75\,m} \right)^{2}\cdot (2900\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)[/tex]
[tex]F_{2} = 854.473\,N[/tex]
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
A shelf has four books on it. The weight, in pounds, of each of the four books on the shelf is listed below.

Which inequality represent the weight, w, of any book chosen from the shelf?
A ) w > 2.3
B ) w < 2.4
C ) w > 3.2
D ) w < 3.3
Answer:
C ) w > 3.2

If 12 oranges cost $4.80, what would be the cost for 5 oranges
Answer: 24
Step-by-step explanation:
Because if you do 4.80 times 5 you’ll get 24 because each orange cost $4.80
Answer:
the cost of 5 oranges would be $2.00
Step-by-step explanation:
To solve this we need to find the unit rate and when we do this we can solve this problem. To find that we need to divide 4.80 by 12 once we do that we just have to multiply that number by 5 to get our answer, when you divide you'll get 0.4 and then multiply that by 5 and you'll get $2.00.

It takes 1/3 of an hour to take down 1/9 of the camp at the YMCA campground. How long does it take the camp staff to take down the entire camp?
Group of answer choices
1/27 of an hour
27 hours
9 hours
3 hours
Answer:
Step-by-step explanation:
1/9 of the camp means it has 9 parts the whole thing (each 1/9)
1/3 of an hour for 1 part and
for 9 parts we have
1/3 *9 = 9/3= 3 hours
factoring is the opposite of what operation
Answer:
Factoring is the opposite of multiplying (or using the distributive property to multiply.)

The population of a town is increasing by 2% each year. If the population today is 40,000, what
will be its population in 8 years?
0 40,000. (0.02)
O 40,000 - (1.02)
0 40,000 - (1.02)
O 40,000. (1.02). (8)
Answer:
46,400
Step-by-step explanation:
present population =40,000
2% of 40,000 =800
for each year it increases by 800
in 8 years time =(8*800) +40,000
=46,400

I have a pile of socks which contains 12 white socks, 12 black socks, and 12 red socks. How many socks must I take from the pile to be certain that I have at least one matching pair?
Answer:
I would say 6 but i do not know
Step-by-step explanation:
bc 6x2=12
The least number of socks to be taken from the pile to have one pair of socks is given by the equation A = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of socks to be taken be represented as A
Now , the equation will be
The number of white socks = 12
The number of black socks = 12
The number of red socks = 12
So , let the first sock be taken be either a white , black or red
Now , the second sock can also be either a white , black or red
And , the third sock can also be either a white , black or red
But , the fourth sock must a white or black or red and it will form a pair of similar colored sock
Therefore , the number of times is 4
Hence , the number is 4

Answer:
D. 6x-14
Step-by-step explanation:
So first we would do 3x^2+3x^2-5x^2
That would all cancel out so that would be 0.
Next we would do 3x-4x+7x, this would equal to 6x
Finally we would do -4-8-2, this would be equal to -14
Then the equation would be 6x-14
All you have to do is combine like terms.
