Answer:
The percentage rate is 4.5%.
Step-by-step explanation:
The given formula for simple interest is I=prt where I=simple interest, p=principle, r = percentage rate and t=time. In the problem, we are told that after six years (t=6), $7000 (p=7000) earns $1890 (I=1890). We can then substitute in the values for three of our variable to get the following: 1890 = (7000)(6)r. Multiplying 7000x6 = 42000 giving us 1890 = 42000r. Using inverse operations, we divide both sides of the equation by 42000 to get 0.045 = r. Since r = percentage rate, we need to multiply our decimal by 100 to find the percentage. 0.045 x 100 = 4.5%.
Answer:
31.4 in
Step-by-step explanation:
This is a tricky question,
if you observe the shape carefully, you will notice that if you mirror (flip outward) each curve surface of each quardrant, what you will end up with is a complete circle with a radius of 5 inches.
Hence the combined length of all the curved surfaces is simply the circumference of the circle, given by:
Circumference = 2πr
= 2 x 3.14 x 5
= 31.4 in
Divide 50 by 22: 2.27272727...
Round up to hundredth and your final answer is 2.27
hope that helps :)
Answer:
1/13
Step-by-step explanation:
Total cards = 52
No: of aces in the cards= 4
Probability = 4/52 = 1/13
I hope im right!!1
The full length of the circumference is
C = 2πr
C = 2π*100 m ≈ 628.32 m
1/3 that distance is (628.32 m)/3 ≈ 209.44 m
Maile walked about 209.4 m.
