Answer:
-7² · 5⁴
Step-by-step explanation:
-7 is being multiplied by itself 2 times and 5 is being multiplied by itself 4 times.
With questions like these, I like to use a system of operations my teacher told me.
First, we have to identify what the question is asking us to find. The question is asking us to find how many bouquets a florist makes per day (which is in one day).
Then, we have to find information that will help us answer the question. She makes 215 bouquets is 5 days.
Now, you put it together!
If she makes 215 bouquets in 5 days, and we need to find out how many she makes in 1 day, we need to divide 215 by 5!
215 / 5 = 43.
The florist makes 43 bouquets per day!
The median is the number in the middle of a list of numbers.
Since this list has an even amount of numbers, you take the 2 middle numbers, add it together, and divide by 2 to get the average value.
The middle values are 17 and 20, so you do:
17 + 20 = 37 now divide by 2
37/2 = 18.5
Given:
Total amount invested = $9,000
interest rates = 4% and 6%
Let x be the part of 9,000.
Note that annual return on each investment is the same.
0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400
0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216
total interest for the year : 216 + 216 = 432
Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate
Interest rate would be 4.8% to get the same interest from the whole 9,000.
575 ft = 575 · 304.8 = 175,260 mm
Number of the coins ( quarters ) in this stack:
175,260 : 1.55 = 113,071
The weight of this stack:
113,071 · 5.67 g = 651,288.26 g = 651.28896 kg
It contains:
113,071 · $0.25 = $28,267.75
$11,687,233,914,811.11 : $28,267.75 = 413,447,618.4 stacks like one described would be necessary to pay US debt.
