Nakisa spent 328 on a total of CDs and DvDs. If Cds coat 12.00 and DVDs coat 16.00 each, how many CDs did Nakisa buy?
Answers
Answer:
[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]
Step-by-step explanation:
1) Set up an equation
Let c be the number of CDs Nakisa bought.
Let d be the number of DVDs Nakisa bought.
[tex]328=12c+16d[/tex]
Explanation: Each CD costs $12 and each DVD costs $16. Nakisa spent $328 altogether, which means $12c+$16d is equal to $328.
The question is asking for the number of CDs that Nakisa bought, so our goal is to isolate c in the equation above.
2) Isolate c
[tex]328=12c+16d[/tex]
Subtract both sides by 16d
[tex]328-16d=12c+16d-16d\\328-16d=12c[/tex]
Divide both sides by 12
[tex]\frac{328-16d}{12}=\frac{12c}{12} \\\frac{82}{3}-\frac{4}{3}d=c[/tex]
[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]

John drove 504 miles in 8 hours. At the same rate, how many miles would he drive in 13 hours?
Answers
The distance travelled by John in 13 hours is 819 miles.
What are arithmetic operations?The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.
The total distance covered in 8 hours is 504 miles.
Then in one hour, distance covered is given as below,
⇒ Number of miles ÷ Number of hours
⇒ 504 ÷ 8 = 63
Then, the distance covered in 13 hours is given as,
⇒ Unit distance in 1 hour × Number of hours
⇒ 63 × 13 = 819
Hence, the miles travelled in 1 hour is given as 819 miles.

Answers
Answer:
Las coordenadas del punto son P([tex]2.\overline 3[/tex], 1)
Step-by-step explanation:
Las coordenadas de los extremos de la pieza de madera son A (5, 3) y B (-3, -3)
El punto, P, en el que se agregará la muesca = 1/3 de la longitud de AB
Por tanto, las coordenadas del punto, tomando A como punto de referencia, se dan como sigue;
P (5 + (-3 - 5) × 1/3, 3 + (-3 - 3) × 1/3) = P([tex]2.\overline 3[/tex], 1)
Las coordenadas del punto son P([tex]2.\overline 3[/tex], 1).

The work W required to move a particle from a far distance to within radius r of another particle varies jointly as the product of the two particles' charges q1 and q2 and inversely as the radius r. Write a formula that models this proportion. (Use k as the constant of variation.)
Answers
Answer:
W = kq1q2 / r
Step-by-step explanation:
W varies jointly as the product of q1 and q2 and inversely as radius r
Product of q1 and q2 = q1q2
W = (k*q1"q2) / r
W = kq1q2 / r
Where,
W = work
q1 = particle 1
q2 = particle 2
r = radius
k = constant of proportionality
The answer is W = kq1q2 / r
Using proportions, it is found that the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]
Work varies jointly as the charges, thus, the charges are in the numerator.Inversely as the radius, thus, the radius is in the denominator.There is a constant of proportionality k, which multiplies the fraction;Then, the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]
