An estate valued at $510,000 is to be distributed among the wife, 2 children, and 3 grandchildren. The children each receive two

4vir4ik [10]

Each grandchild receives x.

Each child receives 2 times as much as a grandchild, so each child receives 2x.

The wife receives 5 times as much as a child, so the wife receives 5 * 2x = 10x.

There is 1 wife: 10x

There are 2 children: 2 * 2x = 4x

There are 3 grandchildren: 3x

Total: 10x + 4x + 3x = 17x

17x = 510,000

x = 30,000

Answer:

Each grandchild gets $30,000.

Each child gets 2 * $30,000 = $60,000.

The wife gets 10 * $30,000 = $300,000.

In a game show, players play multiple rounds to score points. Each round has 3 times as many points available as the previous ro

Juli2301 [7.4K]

Answer:

$p = 25(3)^n$

Step-by-step explanation:

Given

Round 0 1 2 3

Points 25 75 225 675

Required

Determine the equation

Let n = rounds and p = points.

So, we have:

$(n_1,p_1) = (0,25)$

$(n_2,p_2) = (1,75)$

$(n_2,p_2) = (3,225)$

The above shows a geometric progression.

So, we solve using

$p = ab^n$

In $(n_1,p_1) = (0,25)$

n = 0 and p = 25

Substitute these values in $p = ab^n$

$25 = ab^0$

$25 = a*1$

$25 = a$

$a = 25$

In $(n_2,p_2) = (1,75)$

n = 1 and p = 75

Substitute these values in $p = ab^n$

$75 = ab^1$

$75 = ab$

Substitute 25 for a

$75 = 25*b$

Make b the subject

$b = \frac{75}{25}$

$b = 3$

So, we have:

$a = 25$ and $b = 3$

The equation $p = ab^n$ becomes

$p = 25(3)^n$

How to solve r^2/2r^3 step by step please

ZanzabumX [31]

Can't solve this, because it's not an equation. It's an expression, and I think your goal is to simplify it.

<span>r^2/2r^3 would be better written as

</span><span> r^2 r^2
------- = ----------- this should be reduced by cancelling "r^2:"
2r^3 2r(r^2)

1
-------- (answer)
2r</span>

A graph of a quadratic function is shown below. graph of y equals negative 2 times x squared plus 40 x plus 600 Which of the fol

Leno4ka [110]

Answer:

Option c. (0,800)

Step-by-step explanation:

The options for your question are attached in th epicture below

The function represented in the graph is

y = -2*x^2 + 40*x + 600

We just need to verify if each ordered pair belongs to the function

a. (-10,0)

y = -2*(-10)^2 + 40*(-10) + 600

y = 0

It is an intercept

b. (0,600)

y = -2*(0)^2 + 40*(0) + 600

y = 600

It is an intercept

c. (0, 800)

y = -2*(0)^2 + 40*(0) + 600

y = 600 ≠ 800

It is not an intercept
