5764801 * 7= 40353607
A. 7^3*7^3= 343*343= 117649 <--- not the answer
B. 7^18/7^9= 40353607 <---- right answer
C. (7^3)^3= 343^3= 40353607 <------ right answer
D. 7^5+7^4= 16807+2401= 19208 <---- not the answer
E. 7^5*7^4= 16807*2401= 40353607 <---- right answer
The answer is D
You multiply the denominator with the whole number and and the numerator
Answer:
Step-by-step explanation:
Let the base camp is point A and boats' locations after two hours are points B and C.
By connecting the three points together we get a triangle ABC with sides:
- AB = 50*2 = 100 km
- AC = 70*2 = 140 km
The angle between AB and AC is:
- 60 + 50 = 110 degrees (opposite directions from south)
We are looking for the distance BC, which can be found by using the law of cosines:
- BC² = AB² + AC² - 2AB*AC*cos ∠BAC
- BC² = 100² + 140² - 2*100*140*cos 110°
- BC² = 39176.56 (rounded)
- BC = √39176.56 = 197.93 km (rounded)
The distance between the boats is 197.93 km.
36 throws because you divide 60 by five and get 12 and then multiply 3 by 12 giving you 36, are you sure this is high school
