We own purchase a very opening for $3000 the paining sells a a 325% increase in price. what is the retail price of the painting

1 answer:

6 0

If the owner sold the painting for a 10% increase in price, its retail price would be (1 + 0.1)*($3000) = 1.1*($3000) = $3300.

By the same logic, a 325% increase in price would be (1 + 3.25)*($3000) = 4.25*($3000) = $12,750 retail price.

Find axis of symmetry f(x)=2(x-5)(x+9)

Effectus [21]

Answer:

x = -2

Step-by-step explanation:

f(x) = 2( x^2 +9x -5x - 45)

f(x) = 2(x^2 + 4x - 45)

f(x) = 2x^2 +8x -90

axis of symmetry formula: x = -b / 2a

x = -(8) / 2(2)

x = -8 / 4

x = -2

*you can also graph the equation on a graphing calculator and find the middle of the parabola

The combined age of three relatives is 120 years. James is three times the age of Dan, and Paul is two times the sum of the ages

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

From the problem statement, we can create the following equation:

$J + P + D = 120$

where $J$ is the age of James, $P$ is the age of Paul, and $D$ is the age of Dan.

From the first part of the second sentence, we can set up the following equation:

$J = 3D$

From the last part of the second sentence, we can set up the following equation:

$P = 2(J + D)$

We can substitute the second equation into the last one to get the following:

$P = 2(3D + D)$

$P = 2(4D)$

$P = 8D$

We can then substitute the last two equations in the first to solve for $D$ :

$3D + 8D + D = 120$

$12D = 120$

$D = 10$

Plugging this into the other two equations will give us the remaining ages:

$P = 8D$

$P = 8(10)$

$P = 80$

$J = 3D$

$J = 3(10)$

$J = 30$

If a single card is drawn from a standard 52-card deck, in how many ways can a card other than nine be obtained?

Novosadov [1.4K]

Answer:

48 ways

Step-by-step explanation:

There are 52 cards in a deck and four nines. This means that nines account for 4/52 of the deck. The opposite of 4/52 (idr the math word for that) is 48/52. Therefore, there are 48 other ways that a card other than nine can be obtained.
