Answer:
r=20
Step-by-step explanation:
to get rid of the division part, you multiply 6 each side. now you have r+10=30. to solve, now you subtract 10 from both sides. this gives you r=20 :)
Answer:
Step-by-step explanation:
<u>Given</u>
- Investment P = $16800
- Interest rate r = 5% = 0.05
- Final amount A = $18900
- Time t = ?
<u>Use the formula</u>
- A = P(1 + rt), where A - final amount, P - investment, r- interest rate, t- time
<u>Substitute the given numbers and solve for t:</u>
- 18900 = 16800( 1 + 0.05t)
- 1 + 0.05t = 18900/16800
- 1 + 0.05t = 1.125
- 0,05t = 0.125
- t = 0.125/0.05
- t = 2.5 years

Answer:
Step-by-step explanation:
If on the coordinate map, ice cream is located at the point (-8,0) and sprinkles are located at the point (-8,6), we can find the distance between the coordinate points using the formula;
D = √(x2-x1)²+(y2-y1)²
Given
x1 = -8, y1 = 0, x2 = -8 and y2 = 6
Substitute
D = √(x2-x1)²+(y2-y1)²
D = √(-8-(-8))²+(6-0)²
D = √0²+6²
D = √36
D = 6units
Hence the distance between the coordinate points is 6units
