Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula

Answer:
$2268
Step-by-step explanation:
Luna's total mortgage payments for the year would be
... (monthly payment)×(number of months in a year)
... = $2100×12 = $25,200
Of that, 9% went to interest, so the interest amount is ...
... $25,200×9% = $2268

<em>About percentages</em>
Your calculator may do percentages directly. If not, it can be helpful to realize that the percent symbol (%) means the same thing as /100 (divided by 100). So, 9% = 9/100 = 0.09
Your questions are:
1.1. 96 points for 6 games
1.2. 592 students for 17 classrooms
2.1. 15 yd² for $2 per square yard
2.2. 26 ounce at $0.15 per ounce
The first set of problem, that is 1.1. and 1.2 are answered by dividing the numbers.
1.1. 16 points per game
1.2. 34.8 or 35 students per classroom
For the second set, we just have to multiply to get the cost of each.
2.1. $30
2.2. $3.9
Answer:
$5909.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 5575 × 0.03 × 2 = 334.5
I = $ 334.50
The simple interest accumulated
on a principal of $ 5,575.00
at a rate of 3% per year
for 2 years is $ 334.50.
Do up one over 3 and start at 0, that is what I recommend
