Al vender una computadora, un vendedor descuenta el 15%, y aun así gana el 35%, del costo. ¿qué %del costo es el precio de venta?
Answers
Veremos que el precio de venta es el 158% del costo.
¿Que porcentaje del costo es el precio de venta?
Sabemos que con el descuento del 15%, el vendedor gana 35% del costo.
Es decir, si el costo es C, entonces el precio al que se vende la computadora es:
P' = (1 + 0.35)*C = 1.35*C
Pero, esto es con un 15% de descuento. Entonces si el precio de venta es P, tendremos:
P' = (1 - 0.15)*P = (0.85)*P
Reemplazando esto arriba tenemos:
(0.85)*P = 1.35*C
Resolviendo para P:
P = 1.35*C/0.85 = 1.58*C
Para obtener el porcentaje, multiplicamos el coeficiente por 100%.
1.58*100% = 158%.
Es decir, el precio de venta es el 158% del costo.

John Travolta flew his plane last weekend. What would be the angle measure of∠x when his plane reached an altitude of 2500m?
Answers
Answer:
67°
Step-by-step explanation:
Ignore the 2500m for now.
To find angle x, we know that the sum of the degrees in a triangle is 180. We see that under the 2500m there is a square, indicating that the angle is 90 degrees.
So we can do 180-23-90 = 67.
Therefore, the angle measure of ∠x is 67°

[tex]2\sqrt{2[/tex]
Step-by-step explanation:
The ratios of a 45 - 45 - 90 triangle is [tex]1:1:\sqrt{2}[/tex]
To get 4 for the hypotenuse, you need to mulitpy [tex]\sqrt{2}[/tex] by [tex]\sqrt{8}[/tex].
[tex]\sqrt{2}[/tex] x [tex]\sqrt{8}[/tex] = [tex]\sqrt{16}[/tex]
Simplify.
[tex]\sqrt{16} = 4[/tex]
If you simplify the [tex]\sqrt{8}[/tex], it equals [tex]2\sqrt{2}[/tex].
Since the ratio is [tex]1:1:\sqrt{2}[/tex]
The sides will be [tex]2\sqrt{2}:2\sqrt{2}:4[/tex]
Which expression is equivalent to i 233?
1
–1
i
–i
Answers
Step-by-step explanation:
i¹ = i
i² = i×i = -1
i³ = -1 × i = -i
i⁴ = -i×i = - -1 = 1
i⁵ = 1×i = i
...
so, when the exponent of i modulo 4 (the remainder when dividing by 4) = 0, then the result is 1.
= 1, then the result is i
= 2, then the result is -1
= 3, then the result is -i
233 modulo 4 = 1 (233/4 = 58, remainder 1).
so, the result is i (the third answer option).
At his schools book fair, Henry brings $10.00. He purchases a book for $8.50, plus a 6% sales tax. How much money in change will Henry receive?
Answers
0.51 + 8.50 = 9.01
10.00 - 9.01 = 99
He will receive 99 cents in change.
Answer:
$0.99 in change
Explanation:
To apply the sales tax, you have to multiply:
8.50*1.06=9.01
This means that, with tax, the book will cost $9.01. If he gave them $10, he would get 99 cents back because 10-9.01 is 0.99.
