12 gallons for 144 miles
6 galoons for 144/2=72 miles
1 gallon for 72/6=12 miles
if 1 gallon for 12 miles
how many gallons for 324 miles
?.12=1.324
?=324/12
?=27 miles
hi <3
as the value after the thousandth place is 6, you would need to round up
thus, your answer would be 217.727
hope this helps :)
Answer:
B. 147 feet
Step-by-step explanation:
We can easily imagine a right triangle for this problem. The height of the triangle is what we're looking for (x), at the bottom of x, we have the right angle formed by the building and the ground. The other side of that right angle is the distance to the car (300 ft). On top of the x side, we have the angle of 63 degrees looking down, since Craig is looking down by 27 degrees (90 - 27 = 63).
We can easily apply the Law of Sines that says:
Then we can isolate c and fill in the values:
So, we know Craig's eyes are 153 feet above ground... since Craig is 6 feet tall, the balcony sits at 147 feet high (153 - 6 = 147).
To find the probability of drawing certain colour of balls, we first need to find the total number of balls:
5 + 7 +5 = 17
<u>For the number of red balls that need to be added</u>
The original probability of drawing a red ball:
red ball/ total number of balls
= 5/17
To find the number of balls required, we can set an equation.
Let the number of red balls that need to be added be x.
5+x / 17+x = 5/6
(5+x) x 6 = (17+ x) x5
30 + 6x = 85 + 5x
6x - 5x = 85 - 30
x = 55
Therefore, <u>55</u> red balls need to be added.
<u>For the number of black balls that need to be added</u>
The original probability of drawing a white ball:
white ball/ total number of balls
=5/17
To find the probability required, we can set an equation.
Let the number of black balls that need to be added be y.
5/ 17 + y = 1/6
5 x 6 = 17 + y
30 = 17 + y
30 - 17 = y
y = 13
Therefore, <u>13</u> black balls need to be added.
Hope it helps!
