Answer:
x=5
Step-by-step explanation:
cross multiply
45=9x
solve for x by dividing 9 to get x alone
5=x
Answer:
A = 222 units^2
Step-by-step explanation:
To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB (Call this point E). Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units. Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:
(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.
The area of this trapezoid is
A = (average vertical length)(width), which here is:
(21 + 16) units
A = --------------------- * (12 units), which simplifies to:
2
A = (37/2 units)(12 units) = A = 37*6 units = A = 222 units^2
Answer:
Al estudiante le falta caminar 
de kilómetro.
Step-by-step explanation:
Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción 
.
El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción 
, por lo tanto un medio es la mitad de una cantidad. Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:
Resolviendo:
Entonces, la distancia recorrida en bus es de kilómetro.
Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:
Resolviendo:
<u><em>Al estudiante le falta caminar </em></u><u><em> de kilómetro.</em></u>
Answer:
31.95
Step-by-step explanation:
So first you have to identify what the mark up is which would be $9.45
Then you add that to 22.50... And idk what you mean by Round up to two decimal places when necessary.
