a. The interest earned will be $36.
b. The account balance will be $336.
Step-by-step Explanation:
Step 1:
The initial amount put into the account was $300.
This account has an interest rate of 4% every year. So we must calculate how much 4% of $300 is.
4% of $300 = 
Step 2:
So for every year, the interest of $12 is added into the account. To calculate total interest we multiply this interest amount and the number of years.
So after 3 years 
So account balance after 3 years 
.
So the interest earned is $36 and the account balance is $336 after three years.
Answer:
Step-by-step explanation:
We can find the slope (m) by using coordinate pairs of any 2 points located along the slope of the line that we have on the graph.
This, let's use the coordinate pairs at:
x = -4, y = 2 (-4, 2) => (x2, y2)
x = 0, y = -4 (0, -4) => (x1, y1)
Answer:
yes its 5 divided it add it up then its 5
Answer:
221 mm
Step-by-step explanation:
The dimension 74 mm is presumed to mean that the actual length could be anywhere in the interval [73.5, 74.5). So, the minimum perimeter is ...
3 × 73.5 = 220.5 ≈ 221 . . . millimeters
_____
The perimeter of an equilateral triangle is 3 times the side length, since all three sides of the triangle are the same length.
Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200
