Answer:
Elsa sent 15, Lamar sent 30, and Keith sent 23
Step-by-step explanation:
If x=Elsa, L=Lamar, and K=Keith
2x=L
x+8=K
x+x+8+2x= 68
4x+8=68
4x=60
x=15
Then you plug 15 into x, and solve for each person.
(15)2=L
(15)+8=K

Answer:
x = 150
Step-by-step explanation:
The sum of the exterior angles of a convex polygon is 360°.
65° +80° +72° +(x -7)° = 360°
x = 150 . . . . . . divide by °, subtract 210
Answer:
True
Step-by-step explanation:
In this question, we are asked to evaluate the validity of a claim whether true or false.
Firstly, let’s understand what is actually meant by prevalence. Prevalence of a disease actually refers to the proportion of individuals who tested positive to the disease. It is simply the proportion of the individuals in a population that has the disease in question.
In this question, we initially had 50 out of the 500, with 40 who didn’t show symptoms at initial testing showed it later.
This 40 is the number of new cases and is a different term entirely. It is referred to as incidence.
Now to calculate the incidence rate, we apply the following;
Mathematically prevalence can be calculated as number of cases/number of population * 100% = 50/500 * 100% = 10%
This makes the claim correct
$8,000 x 4.5% or $8,000 x .045= $360
Answer:
El período de rotación de la luna no siempre era igual a su órbita alrededor del planeta. Al igual que la gravedad de la luna afecta las mareas del océano en la Tierra, la gravedad de la Tierra afecta a la luna. Pero debido a que la luna carece de un océano, la Tierra tira de su corteza, creando un maremoto en la línea que apunta hacia la Tierra.
