Step-by-step explanation:
6 ÷ 2/3
Copy dot flip
Take the first term. Change the division sign to multiplication. Flip the second term
6 * 3/2
18/2
9
First method: by the rule of three:
126 miles---------------------3 hours
x---------------------------------7 hours
x=(126 miles * 7 hours) / 3 hours=294 miles.
Answer: 294 miles.
Second method:
Speed=distance/ time ⇒distance=speed x time
We calculate the speed of the car:
Speed=126 miles/3 hours= 42 miles/hour.
Data:
Speed=42 miles/hour
time=7 hours
Distance=speed x time
Distance=(42 miles/hour)(7 hours)=294 miles
answer: 294 miles.
First, we have to solve the sides of the right triangle by using the Pythagorean theorem: a² + b² = c² where c is the length of the hypotenuse. Then, we can use the legs as length and height of the triangle and find the area by 1/2(base x height).
x² + 60² = 68²
x² + 3600 = 4624
x² = 1024
x = √1024
x = 32 = length of the other side
A = (1/2)(32) (60) = 960 mm²
