Step-by-step explanation:
<u><em>The complete question is</em></u>
Angelo recently opened a bank account and deposits the same amount each week. After 8 weeks, he deposited $280. He wants to deposit a total of 420 in his account. How many weeks will it Angelo to deposit a total of $420
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Let
x ----> the number of weeks
y ----> the total deposit in the bank account
In this problem we have a proportional relationship between the variables x, and y.
we have the ordered pair (8,280)
Find the constant of proportionality k or slope of the linear equation

so
The linear equation is

For y=420
Substitute in the linear equation

Solve for x

Answer:
El pastel se debe dividir en 6 partes iguales, de las cuales Santiago debe tomar 3 y Alba debe tomar 2.
Step-by-step explanation:
Dado que Santiago quiere comer la mitad de un pastel y Alba quiere un tercio del mismo pastel, para repartirlo bien se deben reducir las fracciones a su común denominador. Así, para determinar en cuántas partes iguales deben dividir el pastel y cuántas partes debe tomar cada uno se deben realizar los siguientes cálculos:
Santiago = 1/2
Alba = 1/3
2 x 3 = 6
Santiago = 1/2 = 3/6
Alba = 1/3 = 2/6
Por lo tanto, el pastel se debe dividir en 6 partes iguales, de las cuales Santiago debe tomar 3 y Alba debe tomar 2.

Step-by-step explanation:
Because it basically means addition meaning you just have to add it 3,489,234 + 100,000 gives you the answer
Answer:
The probability a person selected random is not suffering from Malaria is 0.725.
Step-by-step explanation:
Denote the events as follows:
X = a person is suffering from Malaria
M = a man
W = a woman
The information provided is:
P (M) = P (W) = 0.50
P (X|M) = 0.10
P (X|W) = 0.45
Compute the probability a person selected random is suffering from Malaria as follows:


Then the probability a person selected random is not suffering from Malaria is:
P (X') = 1 - P (X)
= 1 - 0.275
= 0.725
