Answer:
Below
Step-by-step explanation:
Let x be that missing number
One third of it is x/3
One-ninth of it is x/9
Multiply x/3 and x/9
● (x/3)*(x/9) = (x^2/27)
● (x^2/27) = 108
Multiply both sides by 27
● (x^2/27)*27 = 108*27
● x^2 = 2916
● x = √(2,916) or x = -√(2,916)
● x = 54 or x = -54
So there are two possibilities 54 and -54.
Answer:
Answer C
−5x3 + 4x2 − 5x; is a polynomial
Step-by-step explanation:
you just use distributive property to simplify, and then you know the closure property demonstrates that when you are adding, subtracting, multiplying, or dividing two polynomials, they will remain polynomials.

The rate of interest at which Dylan invested is 3.09%.
The practice of adding interest to the principal of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It happens when interest is reinvested, added to the collateral for the loan rather than paid out, or when the borrower is forced to pay it, resulting in interest being created on the principal amount plus any accumulated interest the following period. Compound interest is a prominent concept in finance and economics.
Compound interest allows interest to accumulate over time, in contrast to simple interest, which does not compound because past interest is not returned to the principle for the present period.
principal =360
time =5 years
n=5×4=20 (compounded quarterly)
Amount = 420
Now: 420 = 360(1+r)²⁰
solving for r we get:
r= 0.007737
required rate percent = 0.007737×4 = 0.00193 × 100 = 3.09%
hence the simple annual interest rate is obtained by multiplying the interest per period by the total number of periods in a year is 3.09%.

Answer:
83.333333π
Step-by-step explanation:
the volume of a cone is (1/3) · π · r^2 · h, so 1/3 times pi times 5^2 times 10
which is 83.3pi, or 261.7
X>10
Start by distributing the part on the left
1. 4(2x+2)+12>100
2. 8x+8+12>100
Next calculate
3. 8x+20>100
Now you’ll need to move the constants to the right
4. 8x>100-20
Calculate.
5. 8x>80
Now divide
6. 8x>80
/8 /8
7. X>10
