Answer:
Step-by-step explanation:
We are using the formula I=PRT and calculating simple interest.
<em>I</em> is the interest, <em>P</em> is the principal or starting amount, <em>R </em> is the interest rate as a decimal, and <em>T</em> is the time in years.
We know that there is $1555.00 at 8% for 2 years. First, convert the interest rate to a decimal. Divide the rate by 100 or move the decimal place 2 spots to the left.
- 8/100 = 0.08
- 8. --> 0.8 --> 0.08
Now we know all the values:
Substitute the values into the formula.
Multiply.
The account earned $248.80 in interest, but the question asks for the total amount in the account. We must add the interest to the starting amount.
After 2 years, the savings account had <u>$1803.80</u>
Answer:
- 104 boxes
- 109 boxes
- 218 boxes
Step-by-step explanation:
Let b represent the number of boxes of cookies sold the first week. Then b+5 boxes were sold the second week, and 2(b+5) boxes were sold the third week. The total sold was ...
b +(b+5) +2(b+5) = 431
4b +15 = 431 . . . . . . simplify
b = (431 -15)/4 = 104 . . . . . subtract 15, divide by the coefficient of b
First week: b = 104
Second week: b+5 = 109
Third week: 2(b+5) = 218
Step-by-step explanation:
The ratio of the perimeters = the scale
P₂ / P₁ = 6 / 4 = 3 / 2
The ratio of the areas = the square of the scale
A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4
Same for the triangles:
P₂ / P₁ = 6 / 3 = 2
A₂ / A₁ = (6 / 3)² = (2)² = 4
Answer:
y = 2
Step-by-step explanation:
Algebraic Equation is an equation where alphabets are used to represent numbers.
Solving the above question,
Let the number = y
Therefore,
Sum of the number = y + 3
If it's subtracted from 10 it becomes
10 - ( y + 3 )
The result : 10 - y - 3 = 5
- y = 5 - 10 + 3
- y = -2
Therefore,
y = 2
