Which equation can be used to solve for x in the parallelogram below?
A) 3x-12=6x+12
B) (7x-8)+(6x+12)=90
C) 3x-12=2x+8
D) (7x-8)+(6x+12)=180
Answers
Answer:
B. (3x - 12)° = (2x + 8)°
Step-by-step explanation:
This equation can be used to solve x.
3x - 12 = 2x + 8
3x - 2x = 12 + 8
x = 20°
-------------------------------------------------------------------
Verification:
3(20) - 12 = 2(20) + 8
60 - 12 = 40 + 8

Autumn's family took a road trip to Mount Rushmore. Autumn fell asleep 39% of the way through the trip. If Autumn fell asleep after they had travelled 351 miles, what was the total length of the trip?
Answers
Answer:
900 miles long
Step-by-step explanation:
Given data
Le the total mile of the trip be x
Autumn fell asleep at 39% of the trip, which is equal to 351 miles
so
=39/100*x= 351
0.39x= 351
divide both sides by 0.39
x= 351/0.39
x= 900 miles
Hence the trip is 900 miles long

Determina el número de átomos que tiene una
muestra de 0.7 gramos de uranio puro si la
masa de un átomo de uranio es de 4 x 10^-25 kg
Answers
Tomando el cociente entre la masa de la muestra y la masa de un átomo, veremos que hay 1.7*10^21 átomos de uranio en la muestra.
¿Como podemos determinar el número de átomos?Para determinar el número de átomos en la muestra, simplemente debemos dividir la masa de la muestra (0.7 gramos) por la masa de un átomo de uranio (4*10^(-25) kg)
Donde la complicación viene por que tenemos distintas unidades.
Para resolver esto, podemos escribir la masa de la muestra en kilogramos.
Sabemos que: 1g = 1*10^-3 kg
Entonces podemos reescribir la masa de la muestra como:
0.7g = (0.7)*(10^-3 kg) = 7*10^-4 kg
Ahora si podemos tomar el cociente, el número de átomos esta dado por:
[tex]N = \frac{7*10^{-4}kg}{4*10^{-25}kg} = 1.7*10^{21}[/tex]
Así podemos concluir que hay 1.7*10^21 átomos de uranio en la muestra.
