Answer:

6


Step-by-step explanation:

<u>Converting 7 ft to inches:</u>

7*12=84 inches

  • 34.5 inches is used, and remaining is used for 8\frac{1}{4} in. sections.
  • Let x be the number of 8\frac{1}{4} in. sections. (8\frac{1}{4} can be written as 8.25 inches)

<u>We set up the equation as:</u>

34.5+8.25x=84

Now solving for x would give us the number of 8.25 inch sections:

8.25x=84-34.5\\8.25x=49.5\\x=\frac{49.5}{8.25}=6


Hence, Mario can cut 6 (8.25 inch) sections from the rope

Answer:

The\ number\ of\ 8 \frac{1}{4}\ inches\ of\ section\ of\ rope\ be\ 6.

Step-by-step explanation:

As given

Mario is setting up a new tent during a camping trip.

The tent came with 7 feet of rope.

As 1 foot = 12 inches

Now convert 7 feet into inches.

7 feet = 7 × 12 inches

         = 84 inches

As given

The instructions were to use 34.5 inches of the rope to tie a tarp on top of the tent.

Than

Rope left after tie a tarp on top of the tent = 84 - 34.5

                                                                      = 49.5 inches

As given

The\ remaining\ rope\ should\ be\ cut\ into\ 8 \frac{1}{4}\ inch\ sections\ to\ tie\ the\ tent\ to\ stakes\ in\ the\ ground.

i.e

The\ remaining\ rope\ should\ be\ cut\ into\ \frac{33}{4}\ inch\ sections\ to\ tie\ the\ tent\ to\ stakes\ in\ the\ ground.

Let\ us\ assume\ the\ number\ of\ \frac{33}{4}\ inches\ section\ of\ rope\ be\ x.

Than the  equation becomes

\frac{33\times x}{4} = 49.5

x = \frac{49.5\times 4}{33}

x = \frac{198}{33}

x = 6

1,030 at 4% compounded semiannually for 2 years
kotegsom [21]

Answer: $1114.91

Step-by-step explanation:

The formula for compound interest is

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

Where

A = final amount

P = initial principal balance (1030 for this)

r = interest rate (0.04 for this)

n = number of times interest applied per time period (2 for this)

t = number of time periods elapsed (2 for this)

A= 1030(1+\frac{.04}{2})^{(2)(2)}  \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125

This rounds up to $1114.91
