Answer:
a) 250
b) 125
Step-by-step explanation:
For a, the answer is 250 because if 2 regions are labelled 6, and there are 6 regions, and the spinner is spun 750 times, then we will multiply 2 by 750 and divide the answer by 6.
2 x 750 = 1500
1500/6 = 250
Now, for b, the answer is 125 because 3 is the only prime number there and only one region is labelled 3. So we multiply 1 by 750 (which is 750) and divide by 6.
750/6 = 125.
a = 250
b = 125
40,000,000 m since its in standard form
Answer:
10 and 13
Step-by-step explanation:
Let the two numbers be p and q. p = (1/2)q + 8. p + q = 23. Substituting (1/2)q + 8 for p, we get (1/2)q + 8 + q = 23.
First, subtract 8 from both sides, obtaining (1/2)q + q = 15.
Next, mult. all terms by 2 to eliminate the fraction (1/2): q + 2q = 30.
Then 3q = 30, and q = 10. Then p = (1/2)(10) + 8 = 5 + 8 = 13.
The numbers are 10 and 13.
