Answer:
$7,925.53
Step-by-step explanation:
We'll have to use the compound interest formula: A = P(1 + r/n)ⁿˣ
A = final amount (?)
P = starting amount (5700)
r = rate
n = times applied (12 since its monthly and there 12 months in a year)
x = years (12)
A = 5700(1 + 0.0275/12)¹⁴⁴
A = 7925.525498629932
Answer:
B) 20.6 mi/hr
Step-by-step explanation:
To solve this, we need to first convert 40 meters to mile, then convert 4.35 seconds to hour, then solve by proportion.
converting 40 meters to mile;
1 mile = 1609.344 meter
x = 40 meters
1609.344x = 40
x = 40/1609.344
x =0.02485 mile
Then converting seconds to hour
1 hour = 3600 seconds
y = 4.35 seconds
3600 y = 4.35
y=4.35/3600
y =0.00121 hour
Using proportion to solve the question
Let n be the number he runs miles per hour
0.02485 mile = 0.00121 hour
n = 1 hour
cross-multiply
0.00121 n = 0.02485
Divide both-side by 0.00121
0.00121 n/0.00121 = 0.02485/0.00121
n ≈ 20.6 mile/hour
Therefore, he is running 20.6 mi/hr
Answer:
-8.8
Step-by-step explanation:
We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.
We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.
Now, move 4.3v across by subtracting it from both sides.
Finally, we divide both sides by the coefficient of v.
