Answer:
Explanation:
1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.
2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.
Hence, you must use Pythagoras to find that distance.
3. Pythagoras
- hypotenuse² = leg₁² + leg₂²
- hypotenuse = (12 mile)² + (8 mile)² = 144 mile² + 64 mile² = 208 mile²
, which is rounded to the neartest tenth of a mile.
Answer:
It would be B
Step-by-step explanation:
310-135=175
175/135
Answer:
B. 0.4
Step-by-step explanation:
Use the definition of the probability
You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table
- Number of all possible outcomes = Number of Reference books = 25
- Number of all favorable outcomes = Number of Hardcover Reference books = 10
So, the probability is
You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is
which is in the geometric sequence format. So the answer is choice D
Answer:
27 small cubes
Step-by-step explanation:
Given that,
The volume of the large cube is 
The volume of small cube is 
We need to find how many small cubes make up the large cube. Let there are n small cubes. So, it can be calculated as follows :
So, there are 27 small cubes that make up of the large cube.
