The fabric cost 7cents per square inch. She will only pay for the fabric used to cover the box, even if there is waste or extra.

DIA [1.3K]

Answer:

Shyla will pay about 63 cents to cover the box

Step-by-step explanation:

Length of the box ( l ) = 7 inches

Width of the box (b) = 11 inches

Height of the box (h) = 8 inches

We can solve this equation by following two simple steps.

1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.

We can get this by the following formula:

SA=2( length X width) +2( length X height )+2(height X width)

SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches

2. The second step is to divide the total surface area by the price of the fabric per square inch.

This will be 442 square inches divided by 7 cents per square inch = 63.14 cents

Shyla will pay about 63 cents to cover the box

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

zaharov [31]

After 6 years the investment is $5555.88

Step-by-step explanation:

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

The formula used to find future value is:

$A(t)=P(1+\frac{r}{n})^{nt}$

where A(t) = Accumulated amount

P = Principal Amount

r = annual rate

t= time

n= compounding periods per year

We are given:

P = $3600

r = 7.5 %

t = 6

n = 1

Putting values in formula:

$A(t)=P(1+\frac{r}{n})^{nt}\\A(t)=3600(1+\frac{0.075}{1})^{6*1}\\A(t)=3600(\frac{1.075}{1})^6\\A(t)=3600(1.075)^6\\A(t)=3600(1.543)\\A(t)=5555.88$

So, After 6 years the investment is $5555.88

A fair coin is flipped three times. Events A and B are defined as: A: there are at least two consecutive heads somewhere in the

Vaselesa [24]

Answer:

2 / 7

Step-by-step explanation:

Coin flipped 3 times has following outcomes, of heads 'H' & Tails 'T'

HHH , TTT , HTT, THT , TTH , THH , HTH , HHT = total outcomes

P (A) = 2 consecutive heads , P (B) = atleast one tail

P (A) = 2 outcomes ( HHH , HHT , THH ) / total 8 outcomes = 3 / 8

P (B) = 7 outcomes (all except HHH) / total 8 outcomes = 7 / 8

P (A | B) = P ( A ∩ B ) / P (B)

P ( A ∩ B ) = P ( 2 consecutive heads & atleast one tail) / Total outcomes = 2 outcomes ( HHT , THH ) / total 8 outcomes = 2 / 8

So, P (A | B) = ( 2 / 8 ) / ( 7 / 8 ) = 2 / 7
