Answer:
1.4 years
Step-by-step explanation:
Use the formula for simple Interest:

Where I is the interest gained (in your case $105),
P is the principal (in your case $6000),
r is the annual interest rate in decimal form (in your case 0.0125)
and t is the time (in years) you need to find.
Therefore, we
solve for "t" in the following equation:
Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
(Correct me if i am wrong)
1 ft= 12 inches
1/2 ft= 6 inches
=3 1/2 feet - 6 inches
substitute # of inches in for 1/2 foot
=3 ft 6 inches - 6 inches
=3 feet
ANSWER: 3 feet
Hope this helps! :)
Answer:
Hi there, you can use Pitagoras relationship to solve this up (Without using any other "tool".
Point A is located wheter in (-6,8) or could be located in (-6,8)
Step-by-step explanation:
Point A is 10 units away from the origin, and its x coordinate is -6, using this information, you can draw a triangle from 0 to -6 (the basis) and using 10 as the hypotenuse, so, you have this equation:

solving for Y variable, you have this
y=±
Note the combined sing ±, meaning that y=8 is a valid answer and that y= -8 is also a valid answer.
Hope It helps
