Answer: Bea has $30 saved
Step-by-step explanation:
Add 10: 50+10=60
Divide by 2: 60/2=30
Total mold spores at end of 9.30 am is 26901.
Step-by-step explanation:
Number of molds = 14000
Rate = 9.7% per hour
Number of hours = 12 am to 9.30 am = 9
hours
Growth of mold = 14000 * 9.7% * 9
= 12901
Total mold spores at end of 9.30 am = 14000 + 12901
= 26901
Hence, the expected number of mold spores at 9.30 am is 26901.
Answer:
The expression for the other number is (n-1)
Step-by-step explanation:
we know that
The difference between two consecutive number is equal to 1
Let
x ----> the smaller of two consecutive number
n ----> the larger of two consecutive numbers
we have that

Solve for x

therefore
The expression for the other number is (n-1)
Step-by-step explanation:
length = x - 5
width = 2x
2x(x-5) = 150 m^2
2x^2 - 10x = 150 m^2
2x^2 - 10x - 150 = 0
(x=11.51 or x = -6.513)
if you wanna check,
2(11.51) × (11.51-5) = 150
23.02 × 6.51 = 150
149.8602 = 150
I'm not sure if its correct though^^
The horizontal line is refered to as a fraction bar or a vinculum. There are also other names, but these two are the ones I know the best.
