Scott invests $1000 at a bank that offers 6% compounded annually. Write an equation to model the growth of the investment.

soldi70 [24.7K]

You can use A=P(1+(r/n))^(nt)
n=homany times it is compounded a year: 1 annually
t=time in years
r=rate: 6% or .06
A=Final Amount
P=principle amount

A=1000(1+(.06/1))^(1*t)

Allushta [10]

The selling price is 2.5 times the cost. If the cost goes up by 0.25, the selling price needs to go up by 2.5*0.25 = 0.63 in order to maintain the gross margin.

Marissa claims that stacking 6 blocks with dimensions of One-half times 1 times 1 will give the same volume as stacking 9 blocks

quester [9]

Answer:

(A)Six of the one-half cubes would have a volume of 3 cubic units.
(D)Three of the one-third cubes will make 1 unit cube.
(E)Two of the one-half cubes will make 1 unit cube.
(F)Both stacks will have a volume of 3 cubic units.

Step-by-step explanation:

Marissa claims that stacking 6 blocks with dimensions of $\frac{1}{2}X1X1$ will give the same volume as stacking 9 blocks with dimensions of $\frac{1}{3}X1X1$ .

First, let us examine the volume of each of the blocks.

<u>For Block 1</u>

The dimensions are: $\frac{1}{2}X1X1$

Volume of 1 block = $\frac{1}{2}X1X1= \frac{1}{2} $ cubic units$

Volume of 6 blocks of dimension $=6* \frac{1}{2} =3$ cubic units$

<u>For Block 2 </u>

The dimensions are: $\frac{1}{3}X1X1$

Volume of 1 block = $\frac{1}{3}X1X1=\frac{1}{3} $ cubic units$

Volume of 9 blocks of dimension $=9*\frac{1}{3} =3$ cubic units$

The following statements out of Marissa's claim are true:

(A)Six of the one-half cubes would have a volume of 3 cubic units.

(D)Three of the one-third cubes will make 1 unit cube.

$3*\frac{1}{3} =1$ cubic units$

(E)Two of the one-half cubes will make 1 unit cube.

$2*\frac{1}{2} =1$ cubic units$

(F)Both stacks will have a volume of 3 cubic units.
