Answer:
9^8
Step-by-step explanation:
The total number of ants is
(total number of sections)(ants in each section).
let x be the total number of ants.
Substitute the given values.
x = (9^2)(9^6)
x = 9^(2+6) <= exponent rule: when multiplying exponents with the same base, add the exponents.
x = 9^8
Answer:
2.2
Step-by-step explanation:
2.189 to 2 significant figures is 2.2
Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
Answer:
Rs.380
Step-by-step explanation:
Given data
Price= Rs 400.
Discount= 5%
Let us find the amount of the discount
=5/100*400
=0.05*400
=Rs. 20
Hence the amount that should be paid for it is
=400-20
=Rs.380
Answer:
x = 3
Step-by-step explanation:
The two triangles at the left have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 6x−2.
Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 9x−11.
So:
6x − 2 = 9x − 11
9 = 3x
x = 3
