Answer:100$

Step-by-step explanation: since the violin was 50 % off, that just means that the price it is is half of what it normally was , so you just multiple the fifty by 2 to get your answer which is that the violin cost 100$

Answer:

$100

Step-by-step explanation:

The price we are given already has the discount on it, so we know that

50% × original price = $50

50% fraction wise is \frac{1}{2} or in decimal 0.5

So: 0.5 × original price = $50

original price = \frac{50}{0.5} = $100

According to the graph, what is the value of the constant in the equation below?
Vera_Pavlovna [14]

Answer:

C. 20

Step-by-step explanation:

Take a value from the x-axis (Width) and the y-axis (Height) and substitute them into the equation. I'll use the point (5, 4).

Height = Constant/Width

4 = Constant/5 (Given)

20 = Constant (Multiplied 5 on both sides)

Answer:

3x2+15x=18

Step 1: Subtract 18 from both sides.

3x2+15x−18=18−18

3x2+15x−18=0

Step 2: Factor left side of equation.

3(x−1)(x+6)=0

Step 3: Set factors equal to 0.

x−1=0 or x+6=0

x=1 or x=−6

RSB [31]
The mug cost $12 as it is, so first you subtract 12 from 34, which is 22. From there, you divide 22 by 2.20, which would be 10. Therefore, she can get a mug and 10 refills for $34.

Compound Interest Rate Formula: \displaystyle A = P(1 + \frac{r}{n})^{nt}

  • A is final amount
  • P is principle amount
  • r is rate
  • n is compound rate
  • t is time (in years)

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

P = $1900

r = 3% = 0.03

n = 4

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute [CIRF]:                    \displaystyle A = 1900(1 + \frac{0.03}{4})^{4(6)}
  2. (Parenthesis) Divide:              \displaystyle A = 1900(1 + 0.0075)^{4(6)}
  3. (Parenthesis) Add:                  \displaystyle A = 1900(1.0075)^{4(6)}
  4. (Exponents) Multiply:             \displaystyle A = 1900(1.0075)^{24}
  5. Exponents:                             \displaystyle A = 1900(1.19641)
  6. Multiply:                                  \displaystyle A = 2273.19
