Answer: 87 feet
Step-by-step explanation:
The angle between the pilling is 60°
The adjacent side of the right angle is 150
So let the distance between the pilling be y, that is opposite side.
Opposite / adjacent = tan (60°)
y / 150 = tan (60)
y × tan (60°) = 150
Divide both side by tan (60°)
y = 150 / tan (60°)
y = 150 / 1.7321
y = 87 feet
We have to determine the number which is rounded to the nearest tenth in the expression 0.304
1.325.
So, let us divide 0.304 by 1.325.
So, we get 
= 0.229
Now, we have to round the number 0.229 to the nearest tenth.
The tenths place is to the right of the decimal. Now, we will consider the digit at hundredths place which is '2', which is less than 5.
Therefore, the number rounded to the nearest tenth is 0.2.
Answer:
x = 35
Step-by-step explanation:
5(x + 20) = 7x + 30
Distribute the 5 on the left side by multiplying 5 by the two terms, x and 20.
5x + 100 = 7x + 30
Subtract 7x from both sides.
-2x + 100 = 30
Subtract 100 from both sides.
-2x = -70
Divide both sides by -2.
x = 35
