be after 5 years.
A. 390
B. 150
CC. 680
D. 340
Answers
Answer:
A. 390
Step-by-step explanation:
An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].
Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.

Answer:
45
Step-by-step explanation:
If you write it out it will look like this, 2x+45+x=180
3x+45=180
3x+45=180
-45 -45
3x=135
/3 /3
x=45
Answer:
x=45
Step-by-step explanation:
Straight angles/lines are equal to 180 degrees. If you add the equations together to get 180 and simplify you'll find the answer. So, start out with the equation 2x+45+x=180.
1. Add like terms. 3x+45=180
2. Subtract 45 from both sides. 3x=135
3. Divide by 3 on both sides to get x by itself. x=45
4. Just to make sure, plug in 45 for x. 2(45)+45+45=180. Sure enough, it works!

The art club at a community college is selling burgers at lunchtime as a fundraiser. The club spends $8 for condiments and supplies. The cost of the meat and bun for each burger is $0.65. Express the total cost, C, as a function of the number of burgersmade, x.
Answers
Answer:
C(x)=0.65x+8
Step-by-step explanation:
According to the information given, you can say that the total cost would be equal to the result of multiplying the cost of the meat and bun per burger for the number of burgers made plus the amount spent on condiments and supplies, which can be expressed as:
C(x)=0.65x+8, where:
C(x) is the total cost
x is the number of burgers made

Find the value of x and the measure of each angle:
Answers
Answer:
m<M= 85° m<N= 85°
Step-by-step explanation:
To find the value of x we should...
Sum of all angles = 360°
95+95+10x-5+8x+13 = 360
198+18x = 360
18x = 360-198
18x = 162
x = 162÷18
x = 9
m<M = (10×9)-5 = 90-5 = 85°
m<N = (8×9)+13 = 72+13 = 85°
PLZZZ MARK ME AS BRAINLIEST PLZZZ
Answer:
x = 9
∠M = 85°
∠N = 85°
Step-by-step explanation:
360 = 95 + 95 + (10x-5) + (8x + 13)
reduce:
18x = 162
x = 9
∠M = 85°
∠N = 85°
