Answer:
About 6,785 people will be infected about nine months.
Step-by-step explanation:
We can write an exponential function to represent the situation. The standard exponential function is given by:
Where <em>a</em> is the initial value, <em>r</em> is the rate, and <em>x</em>, in this case, is the time that has passed in months.
3,124 people have already been infected. Thus, our initial value <em>a</em> = 3124.
And an additional 9% will be infected per month. Therefore, our rate <em>r</em> will be 1 + 9% or 1.09.
Hence, our function is:
Then after nine months, the total amount of infected people will be f(9):
Use a calculator:
About 6,785 people will be infected about nine months.
Answer: Jeanettes ticket was less than the original price by 28%
Step-by-step explanation:
The original price of the ticket was $75. She used a coupon code to receive a 20% discount. This means that the amount of discount that she got is
20/100 × 75 = 15
The discounted price would be
75 - 15 = $60
The website apply to 10% service fee to the discounted price. This means that the amount of service fee charged by the website is
10/100 × 60 = $6
The final cost of the ticket is
60 - 6 = $54
The difference between the final price and the original price is
75 - 54 = 21
The percentage difference in the prices would be
21/75 × 100 = 28%
Green = g
Blue = b
Red = r
g+b = 1500
g+r = 750
g+b+r = 2000
in the 1st equation solve for b
g+b =1500
b = 1500-g
2nd equation solve for r
g+ r = 750
r = 750-g
now substitute the answers fro. b and r into the final equation.
g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250
So we k own the green bike is $250.
Blue = 1500- g
blue = 1500-250= $1250
red = 750-g
red = 750-250 = $500
Answer:
130°
Step-by-step explanation:
angle TFM + angle MFD = 180° (being a linear pair)
or, 4m + 142° +2m + 56°= 180°
or, 6m= 180°- 198°
or, m= -18°/6
so, m= -3°
now, angle TFM = 4m +142°= -12°+142°= 130°
