Answer:
the answer of given question is $400.
Step-by-step explanation:
We distribute first:
(9.5*a)+(9.5*4)= 9.5a+38
We can subtract the a from 9.5a.
9.5a-a=8.5a
The answer is 8.5a+38
I'm so sorry if i'm wrong!
Answer:
c. first year: 240,000
second year: 150,000
Step-by-step explanation:
We let the number of cars made in the second year be X. Consequently, the number of cars made in the first year would be X+90000 since we are told that 90,000 more cars were made in the first year than in the second year. Furthermore, we are also told that the total number of cars constructed in these two years is 390,000, implying that;
X+X+90000=390000
2X+90000=390000
2X=390000-90000
2X=300000
X=150000; number of cars made in second year
The number made in the first year is thus;
150000+90000 = 240000
Answer:
Step-by-step explanation:
a)
This is not a rational expression.
This is a polynomial with 3 terms.
b)
This is not a rational expression because the denominator is constant =1
This is a polynomial with 3 terms.
c)
This is not a rational expression because the denominator =1, a constant. This is a polynomial with 4 terms.
d)
This is a rational expression because the denominator contains a variable.
e)
This is not a rational expression because the denominator contains a constant 1
This is a polynomial with 5 terms.
Answer: 6π
Step-by-step explanation:
Area of a circle = πr².
To find the circumference, we have to find the radius first
Since the area of the circle in question is 9πcm²
9π = πr²
r² = 9π/π
r² = 9
r = +/-√9
= +/- 3.
To find the circumference now, we substitute for r in the formula above
Circumference = 2πr
= 2 x π x 3
= 6π.
Don't forget the π there must not be define
So the answer = 6π
