Speed=distance / time; ⇒distance=speed * time
Distance traveled by Ricardo
Distance (Ricardo)= (3 ft / s) * 15s+3 ft/s * time=45 ft+3 ft/s*t=45+3t
Distance traveled by John:
Distance(John)=(4 ft/s) * time=4t
Distance traveled by Ricardo=Distance traveled by John
3t+45=4t
Answer: D. 3t+45=4t
Answer:
57% to the nearest whole number
Step-by-step explanation:
That is (80/139.3) * 100
= 0.5743 * 100
= 57.43%.
Answer:
7/25
Step-by-step explanation:
The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4. 4 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 28 and 100.
For this case we have a quadratic equation,
, of the form 
Where:

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:

Then, the factorization is given by:

The roots are:
