Answer:
3/5 mile/h
Step-by-step explanation:
velocity = distance / time
then 1/5 / 1/3 = 1/5 * 3/1 = 3/5
Se sabe que el virus SARS-CoV-2 es de forma aproximadamente esférica cuyo diámetro del virus se ha encontrado para colocar entre 50 nanómetro a 140 nanómetro. Halle la dimensión para dicho volumen a) L2T b) L3 c) L4 d) ML3
Answer:
L³
Step-by-step explanation:
De la pregunta anterior se nos dice que el diámetro del virus esférico
= 50 - 140 millas náuticas
Radio = 50 - 140 nm / 2
= 25 - 70 millas náuticas
El volumen de una esfera es
= 4/3 πr³
Usando el análisis dimensional
4/3 = constante
π = constante
[r] = Dimensión de longitud = L
Por lo tanto, la dimensión del volumen de la esfera = L³

Find the solution of the system of equations.
-9x - 5y = -18
4x + 5y = 33
Answer:
x=-3, y=9. (-3, 9).
Step-by-step explanation:
-9x-5y=-18
4x+5y=33
---------------
-5x=15
x=15/-5
x=-3
4(-3)+5y=33
-12+5y=33
5y=33-(-12)
5y=33+12
5y=45
y=45/5
y=9
Answer:
-9x - 5y = -184x + 5y = 33
Find the limit of the function algebraically.
Given:
The given limit problem is:
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]
To find:
The value of the given limit problem.
Solution:
We have,
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]
In can be written as:
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{x^2}{x^4}+\dfrac{3}{x^4}[/tex]
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{1}{x^2}+\dfrac{3}{x^4}[/tex]
After applying limits, we get
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\dfrac{1}{0^2}+\dfrac{3}{0^4}[/tex]
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty+\infty[/tex]
[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty[/tex]
Therefore, the value of the given limit problem is [tex]\infty[/tex].

Con las cuatro cartas que se muestran en la figura se pueden formar diferentes números. Por ejemplo: 8232 o 3822. ¿Cuántos números pares de cuatro dígitos y diferentes puedes formar con estas cuatro cartas? ayuda es para un examen TT
Answer:
Se pueden formar 9 números pares.
Step-by-step explanation:
Dado que con cuatro cartas se pueden formar diferentes números, como por ejemplo 8232 o 3822, para determinar cuántos números pares de cuatro dígitos y diferentes puedes formar con estas cuatro cartas se debe realizar la siguiente tabla:
8232 - 8322 - 8223 = 2 pares 1 impar
2832 - 2823 - 2382 - 2328 - 2283 - 2238 = 4 pares 2 impares
3822 - 3282 - 3228 = 3 pares
Por lo tanto, se pueden formar 9 números pares.
£490 is divided between Richard, Stephen & Bridget so that Richard gets twice as much as Stephen, and Stephen gets three times as much as Bridget. How much does Stephen get?
Answer:
Stephen gets £147
Step-by-step explanation:
Given
Let
[tex]S = Stephen; B = Bridget; R = Richard[/tex]
So:
[tex]S + B + R = 490[/tex]
[tex]R = 2S[/tex]
[tex]S = 3B[/tex]
Required
Find S
Make B the subject in [tex]S = 3B[/tex]
[tex]B = \frac{S}{3}[/tex]
Substitute: [tex]R = 2S[/tex] and [tex]B = \frac{S}{3}[/tex] in [tex]S + B + R = 490[/tex]
[tex]S + \frac{S}{3} + 2S = 490[/tex]
Take LCM
[tex]\frac{3S + S + 6S}{3}= 490[/tex]
[tex]\frac{10S}{3}= 490[/tex]
Solve for S
[tex]S = \frac{490 * 3}{10}[/tex]
[tex]S = 49 * 3[/tex]
[tex]S = 147[/tex]
Stephen gets £147

Jessica is buying several bunches of bananas to make desserts for a fundraiser. She can buy 10 pounds of bananas for $14.90 or 8 pounds of bananas for $12.08.
Part A
How much does each pound of bananas cost in each case?
Drag the tile with the cost of each pound to the correct box.
Each tile may be used once or not at all. And part b plz help
Each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.
What is Pound?The standard unit of money in the United Kingdom, equivalent to 16 ounces (or 0.454 kilograms), is used in most English-speaking countries. For more information, see measure. also known as the pound sterling.
According to question:Let the cost per pound of bananas be represented by x. Then we can set up the following system of equations:
[tex]10x &= 14.90 \\8x &= 12.08[/tex]
Solving for $x$ in each equation, we get:
x = 14.9/10 = 1.49
x = 12.08/8 = 1.51
Therefore, each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.

Trevon and Ashley are selling cookie dough for a school fundraiser. Customers can buy packages of chocolate chip cookie dough and packages of gingerbread cookie dough. Trevon sold 6 packages of chocolate chip cookie dough and 2 packages of gingerbread cookie dough for a total of $72. Ashley sold 6 packages of chocolate chip cookie and 10 packages or gingerbread cookie dough for a total of $216. What is the cost if each of one package of chocolate chip cookie dough and one package of gingerbread cookie dough
Answer:
the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Step-by-step explanation:
The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:
Let us assume the package of chocolate chip cookie be x
And, the package of ginger bread is y
So,
According to the question
6x + 2y = $72
6x + 10y = $216
Now subtract equation 1 from equation 2
-8y = -144
y = $18
And, for x it would be
6x + $36 = $72
x = $6
Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
