Step-by-step explanation:
<u>Suma de Progresiones Artiméticas </u>
Una progresión aritmética es aquella en la cual, cada término se obtiene como el anterior mas una cantidad fija llamada diferencia común. El término general de una progresión aritmética es
Donde es el primer término, n el número de términos y r la diferencia común o radio. La suma de los primeros n términos se calcula como:
En nuestro ejercicio, se deben sumar los números impares entre 20 y 50, se forma la progresión
21, 23, 25, 27, ....49
Sabemos que
Primero averiguamos cuántos términos son, despejando n del término general
La progresión tiene 25 términos
Ahora la suma es
La suma de los impares entre 20 y 50 da 875
Answer:
Step-by-step explanation:
In representing mixed numbers on a number line, we need first to pay attention to the denominators. Here, denominators are 8 and 5, their least common multiple is 40, so, we will need to cut up space between two numbers on the number line on 40 pieces. Also, we have 5 and 3 wholes at these mixed numbers, so, our answer is going to be greater than 8.
We will cut the space between 8 and 9 on a number line on 40 pieces, and we will add and
and get :
So, on a number line between 8 and 9 we need to count 31 out of 40 pieces and that is the result, 8 wholes and .
Answer:
The percentage is <u>55%</u> when weight limit is 33 pounds.
The percentage is <u>190%</u> when weight limit is 114 pounds.
The 95% of the limit weighs <u>57</u> pounds.
Step-by-step explanation:
Given:
Weight limit of rocking horse = 60 pounds.
We need to find:
a) What percentage of the weight limit is 33 pounds.
b)What percentage of the weight limit is 114 pounds.
c) What weight is 95% of the limit.
Now Solving for a we get;
Weight limit = 33 pounds
Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;
framing in equation form we get;
percentage of the weight limit =
Hence The percentage is <u>55%</u> when weight limit is 33 pounds.
Now Solving for b we get;
Weight limit = 114 pounds
Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;
framing in equation form we get;
percentage of the weight limit =
Hence The percentage is <u>190%</u> when weight limit is 114 pounds.
Now Solving for c we get;
Percentage Weight = 95%
Now Amount of weight limit can be calculated by multiplying Percentage weight limit with total weight limit and then Dividing by 100 we get;
framing in equation form we get;
percentage of the weight limit =
Hence The 95% of the limit weighs <u>57</u> pounds.
