4 0

Answer:

1 package

Step-by-step explanation:

First you subtract 32 and 24 which gets you 8. 8 divided by 8 is 1. This means that you will only need 1 package.

Levi invested $5,300 in an account paying an interest rate of 2.4% compounded daily. Assuming no deposits or withdrawals are mad

suter [353]

Answer: $6,120.86

Step-by-step explanation:

Formula to calculate the accumulated amount in n years (compounded daily) is given by :-

$A=P(1+\dfrac{r}{365})^{365\times n}$

P= Initial amount

r= Rate of interest ( in decimal)

As per given , we ahve

P= $5300

r= 2.4%=0.024

n= 6 years

Put these values in formula , we get

$A=5300(1+\dfrac{0.024}{365})^{365\times6}\\\Rightarrow\ A=5300(1.00006575342)^{2190}\\\Rightarrow\ A=6120.85673631\approx6120.86$

Hence, there would be $6,120.86 in the account after 6 years.

The surface areas of two cubes have a ratio of 49to 81. What is the ratio of the edge lengths of the two cubes

taurus [48]

Answer:

Btw, this isn't my answer someone else answered this same question, but here's the credits to amanksingh010

Step-by-step explanation:

Ratio of their volumes => 343:729

Step-by-step explanation:

Let "a" be the side of 1st cube, and

"b" be the side of 2nd cube.

Given, ratio of surface areas of two cubes are 49:81

Hence, 6a^2/6b^2 = 49/81 [Surface area of a cube=6(side)^2]

6 will cancel out, i.e., => a^2/b^2 = 49/81

=> (a/b)^2 = 49/81

=> a/b = 7/9 [49 is square of 7 and 81 is square of 9]

So, we got the side of 1st cube 'a' = 7 and,

side of 2nd cube 'b' = 9

Ratio of their volumes =>

a^3/b^3 = 7/9 [Volume of a cube = (side)^3]

(a/b)^3 = 7/9 => (7/9)^3 => 343/729

Ratio => 343:729
