Usando proporciones, hay que los $12,000 restantes deben ser investidos a una tasa de 11%.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total.
De las dos primeras inversiones, el ingreso es dado por:
0.08 x 15000 = $1,200.
0.09 x 22000 = $1,980
T = 1200 + 1980 = $3,180
Por la tercera inversión, busca-se un retorno de 4500 - 3180 = $1,320.
De esa forma, la tasa x es la seguiente:
12000x = 1320
x = 1320/12000
x = 0.11.
Los $12,000 restantes deben ser investidos a una tasa de 11%.

Answer:
x = √30
Step-by-step explanation:
From small triangle BDC:
using Pythagorean theorem
CB² = BD² + DC²
x² = BD² + 3²
Fron triangles BDC and ADB.
ΔBDC has long leg BD and short leg DC.
ΔADB has long leg AD and shirt leg BD.
AD : BD = BD : DC
7 : BD = BD : 3
7*3 = BD*BD
BD² = 7*3 = 21
x² = BD² + 3² = 21+9 = 30
x² = 30
x = √30
Answer:
.55555555 infinitely or .556
Step-by-step explanation:
The mean of a set of numbers is the average. In this problem, add all of the numbers together ( negative numbers for the losses) and then divide by the amount of games total.
Here are the numbers we have to use:
+7
-3
-2
+4
+9
the problem would be 7-3-2+4+9=15
Now divide 15 by your total amount of games which would be 5.
15/5=3
The average difference would be 3. Now a rule in math is to answer a word problem with a sentence.
The mean difference in scores over the five games played would be 3.
Hope this helps!
