Answer:
Shorting distance = 6 km
Step-by-step explanation:
Given:
Distance walk = 7 km west
Distance walk = 24 km north
Find:
Shorting distance
Computation:
Using Pythagorean theorem:
Magnitude AB = √AC² + BC²
Magnitude AB = √7² + 24²
Magnitude AB = √49 + 576
Magnitude AB = 25 Km
Total distance Nick walk = 7 km + 24 km
Total distance Nick walk = 31 km
Shorting distance = 31 km - 25 km
Shorting distance = 6 km
Answer:
savings = $360
spending = $160.
Step-by-step explanation:
saving : spending
9 : 4
total amount = $520
add the two parts in the ratio(9+4) to get the total parts.
9 + 4 = 13parts . so, 13 parts = 520.
what about 9 and 4?
13 = 520
9 = ?
9 × 520/13 = 360
4 × 520/13 = 160.
hope this helps.
D because a negative - becomes a positive when multiplied or divided by another negative
Result: <u>Circumference = 150.72cm</u>
Explanation:
To find the circumference, C, we will use this formula:
C = 2 * 3.14 * r
Substitute:
C = 2 * 3.14 * 12
Multiply:
2 x 12 = 24
24 x 3.14 = 75.36
___________________________________________________________
And since the question asked for two revolutions.
All we need to do is multiply 75.36 by 2:
75.36 x 2 = <u>150.72</u>
