Solnce55 [7]

Answer:

15.40(approximately).

Step-by-step explanation:

The current price is $750900.

The last year the price was $650700.

Amount increase in the price is $(750900 - 650700) = $100200.

Hence the percentage is $\frac{100200}{650700} times 100$ = 15.40 (approximately).

gregori [183]

Answer: 13 cm^3

Step-by-step explanation:

The volume of a rectangular prism is the height*width*length.

3 1/4 as a decimal is 3.25.

Now we can plug in the given values into the formula for the volume.

Therefore, the volume = 3.25 cm * 4 cm * 1 cm

= 13 cm^3

Ada, Betty, Chris and David have $45 in total Ada gota 52 fromBetty, Chris tripleshis money and Davids money is cut by hall four

andrezito [222]

Using a system of equations, it is found that initially Ada has $0.385.

For the system, we have that the variables are:

x is Ada's amount.
y is Betty's amount.
z is Chris's amount.
w is David's amount.

$45 total, hence:

$x + y + z + w = 45$

Ada gets 2 from Betty, hence:

$x + 2 = y - 2$

$x = y - 4$

$y = x + 4$

Chris triples his money and David's money is cut by half four of them have the same amount, hence:

$x + 4 = y = 3z = \frac{w}{2}$

Then:

$3z = x + 4$

$z = \frac{x + 4}{3}$

$x + 4 = \frac{w}{2}$

$w = 2x + 8$

Solving for w, we find Ada's initial amount.

$x + y + z + w = 45$

$x + x + 4 + \frac{x + 4}{3} + 2x + 8 = 45$

$4x + 12 + \frac{x + 4}{3} = 45$

$12x + 36 + x + 4 = 45$

$13x = 5$

$x = \frac{5}{13}$

$x = 0.385$

Initially, Ada has $0.385.
