20
Add the two 00's from 500.
You get 2,000.
Step-by-step explanation:
Well, we can focus on the number 5 from 500 and multiply it by 4 to receive the answer of 20 because we can assume the person solving this question knows simple multiplication factors and how to solve 5 times 4. Then, we can add the two zeros from the 500. Thus, it's 2,000.
Hope this helps.
Answer:2,000
Step-by-step explanation:
500x4
take the zeros
5x4=20
then add the zeros

How to write an expression for number of tokens needed for v video games if each game takes 4 tokens
Answer: 4v
Step-by-step explanation:
If 4 tokens are needed for each video game, then you multiply 4 by the number of video games v.
For example, 3 video games, each requiring 4 tokens, would require a total of 12 tokens. This can be also defined as:
v = 3

Sharon deposits $8,000 in a 1-year CD at 2% interest, compounded daily.
What is Sharon's annual percentage yield (APY) to the nearest hundredth of a
percent?
Sharon's annual percentage yield (APY) to the nearest hundredth of a
percent is; 2.02%
How to calculate annual percentage yield (APY)?
We are told that;
Amount Deposited = $8000
Interest = 2%
Using the formula for annual percentage yield (APY), we have;
B = 8000 + (1 + (0.02/365))³⁶⁵⁽¹⁾
B = $8161.61
Interest is;
I = $8161.61 - $8,000
I = $161.61
Thus;
APY = 161.61/8000
APY = 0.0202
APY = 2.02%

What is the perimeter of square STUV? HELP PLSSSS
The perimeter of square STUV is 32.98 units
Calculating perimeterFrom the question, we are to calculate the perimeter of the given square.
To do this, we will determine one side length of the given square
The length of a side is the distance between the two end points
Using the points U and T
U(-7, 9) and T(1, 7)
Using the formula for the distance between two points
d = √(x₂ - x₁)² + (y₂-y₁)²
x₁ = -7
y₁ = 9
x₂ = 1
y₂ = 7
Thus,
The distance, d, between the points is
d = √(1 - -7)² + (7-9)²
d = √(1 +7)² + (-2)²
d = √(8)² + 4
d = √64+ 4
d = √68
d = 8.2462
This means the length of each side of the square is 8.2462 units
l = 8.2462 units
The perimeter, P, of a square is given by
P = 4l
P = 4 × 8.2462
P = 32.9848
P ≈ 32.98 units
Hence, the perimeter of square STUV is 32.98 units

6300 and 530. The value of 3
Answer:
300 and 30 respectively
Step-by-step explanation:
The 3 in each number can be valued at 3 with the same number of 0s as there are digits to the right of the 3.
For example, in 6300, the 3 stands for 300 because there are two digits (0 and 0) to the right of 3. So we know 3 stands for 300 because we add two 0s to the right of 3.

Luis y Mario se encuentran a 240 metros uno del otro. Luis camina a 3 m/seg y Mario camina a 5 m/seg. ¿Qué distancia recorre Mario hasta que logran encontrarse?
Mario viaja 48 segundos para encontrarse con Luis.
La distancia se define como la longitud de la trayectoria real recorrida por una partícula en movimiento. El desplazamiento se define como la distancia más corta entre la posición inicial y final de un cuerpo. La distancia recorrida por una partícula en una unidad de tiempo se conoce como velocidad.
La distancia entre Luis y Mario es de 240 metros.
La velocidad al caminar de Luis es de 3 m/s.
La velocidad al caminar de Mario es de 5 m/s.
La distancia se puede definir como el producto de la velocidad y el tiempo que tarda el objeto.
Por lo tanto,
Para que Mario alcance a Luis,
Distancia = Velocidad × Tiempo
240 = 5 × t
t = 240/5 = 48 sec.
Mario tiene que viajar durante 48 segundos para encontrarse con Luis.

There is the bacterial cell 7 × 10¹ times smaller than the amoeba cell which is the correct answer would be an option (B).
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
We have been given that a bacterial cell is around 5 × 10⁻⁶ m long, while an amoeba cell is about 3.5 × 10⁻⁴ m long.
To determine the number of times smaller is the bacterial cell than the amoeba cell.
⇒ amoeba cell / bacterial cell
⇒ 3.5 × 10⁻⁴ m / 5 × 10⁻⁶ m
Apply the division operation, and we get
⇒ 0.7 × 10⁻⁴ × 10⁶
Adding the exponents of the above terms
⇒ 0.7 × 10⁻⁴⁺⁶
⇒ 0.7 × 10²
⇒ 7 × 10¹
Hence, there is the bacterial cell 7 × 10¹ times smaller than the amoeba cell.

peanuts to make a mixture with 92%
peanuts?
37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.
Total mixture of mixed nuts = 4 kg
60 % of them are peanuts.
So, we will calculate the percentage:
Let x be the amount of peanuts.
60 / 100 x = 4 kg
0.6 x = 4 kg
x = 4 kg / 0.6
x = 6.67 kg
Now let the peanuts added be y
So, 92 % of ( 4 kg + y ) should be peanuts.
So, we get the equation as:
0.92 ( 4 ) + 0.92 y = 6.67 + y
3.68 + 0.92 y = 6.67 + y
0.08 y = 2.99
y = 37.375 kg
Therefore, 37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.
