Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
The best answer is "We can expect 135 of the grandparents to spend less than 2 hours a day online" because about 54% of all people said they spend >2 hours online everyday, and 54% of 250 is 135.
Hope this helps!
Answer:
If B is the midpoint, it means
AC=2AB
8= 2(3x-1)
8= 6x-2
8+2= 6x
10= 6x
x= 10/6
x= 1.67
Hope it helps :-)
Solving for x is easier if
First, remove the parenthesis.
-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9
Next, group the numbers with x on the left side and the rest on the right side.
-3x + 3x = 12 - 9 - 3
0 = 0
So, x has no solution.
