dozen of one score?
Answer:
1/2 dozen of one score is 30%.
Step-by-step explanation:
As we know that 1 dozen = 12 units.
1/2 dozen = 1/2 times 12=6 units
1 score = 20 units.
By using this conversion, we get
6/2 times 100=30%
So 1/2 dozen of one score is 30%

Answer:
[tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]-3 \frac{3}{5}[/tex] ÷ [tex]2 \frac{7}{10}[/tex]
Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.
[tex]- \frac{18}{5}[/tex] ÷ [tex]\frac{27}{10}[/tex]
Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.
[tex]-\frac{18}{5} * \frac{10}{27}[/tex]
[tex]= -\frac{180}{135}[/tex]
Simplify;
= [tex]-\frac{4}{3}[/tex]

What is the interest earned on $3,000 at a rate of 0.04 for 3 years? (Hint: Use the formula i = prt , where i represents the interest earned, p represents the principal, r represents the rate, and t represents the time.)
$3,360
$3,003.04
$360
$120
Answer:
$360
Step-by-step explanation:
You have to calculate the interest earned on $3,000, at the rate of 0.04 for 3 years.
P= $ 3000, R= 0.04 and t= 3 years.
3000 × 0.04 × 3= $360 (Answer)
Hope that helps
Have a good day :)
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)
