Answer:
4.4 m
Step-by-step explanation:
Draw the height of the triangle (perpendicular line from point A to line BC). Since ABC is an isosceles triangle, the height is a perpendicular bisector, so it splits the triangle into two congruent right triangles.
Use Pythagorean theorem to find the height.
c² = a² + b²
(8.5 m)² = (14.5/2 m)² + h²
h ≈ 4.4 m
Answer:
-74.1, is the answer.
Step-by-step explanation:
The answer is m(n)= 11n
If you take the different of the money from 21 cars and 25 cars, you get 44 and since 21 and 25 is only a difference of 4, you’ll divide the 44 earned by the 4 cars washed to get $11 per car and then just make sure to use the correct variables
For this case, the first thing you should do is multiply the rate of decrease by time.
We have then:
(3.6 × 10-2) * (1.8 × 104)
= 648 mm
We are going to convert this number into scientific notation:
= 6.48 * 10 ^ 2 mm
Rounding we have:
= 6.5 * 10 ^ 2 mm
Answer:
The water level in the tank decreases in 6.5 * 10 ^ 2 millimeters in 5 hours
1. 427 and 372
2. 427 is greater than 372
