A​ light-year is the distance that light travels in one year. Find the number of miles in a​ light-year if light travels 1.86 ti
Veseljchak [2.6K]

Number of miles traveled by light in a light-year is 5.952 × 10^12 miles

Step-by-step explanation:

  • Step 1: Find the number of miles (distance) in a light year by using the formula for speed = Distance/Time

⇒ Distance = Speed × Time

                   = 1.86 × 10^5 × 1 yr (convert to seconds)

                   = 1.86 × 10^5 × 365 days × 24 hrs × 60 mins × 60 sec

                   = 1.86 × 10^5 × 31,536 × 10³

                   = 1.86 × 3.2 × 10^5 × 10^7

                   = 5.952 × 10^12 miles

Gerry is knitting a scarf for a friend. She knits a gauge swatch which measures 4 in. by 4 in. If the square is 30 stitches wide
LiRa [457]

Answer:

<u>Gerry will need to knit 135 stitches wide and 351 rows long for make a scarf that is 18 inches wide and 36 inches long.</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Measures of the gauge swatch = 4 inches * 4 inches

Number of stitches wide of the gauge swatch = 30

Number of rows long of the gauge swatch = 39

2. How many stitches wide will she need to knit in order to make a scarf that is 18 inches wide and 36 inches long?

Using Rule of Three Simple we can found that value, this way;

Number of stitches wide for 18 inches wide = (18 * 30)/4

Number of stitches wide for 18 inches wide = 540/4 = 135

<u>Gerry will need to knit 135 stitches wide for make a scarf that is 18 inches wide.</u>

We can found the same way, the rows long:

Number of rows long for 36 inches long = (36 * 39)/4

Number of rows long for 36 inches long = 1,404/4 = 351

<u>Gerry will need to knit 351 rows long for make a scarf that is 36 inches long.</u>

If the rate of inflation is 3.9% per year, the future price p(t) (in dollars) of a certain item can be modeled by the following
KonstantinChe [14]

The current price of the item is $2500 and the price 10 years from today is $3665. 2.

Given exponential function

p(t) = 2500 × (1.039)^t

where t is the number of years from today.

Rate of inflation is 3.9% per year

The computation of the current price of the item and the price 10 years from today is shown below:-

p(t) = 2500 × (1.039)^t

Now, the current price can be found by putting t = 0

p(0) is

p(0) = 2500 \times (1.039)^{0}

= 2500

The price 10 years from today can be found by putting t = 10

p(10) is

p(10) = 2500 \times (1.039)^{10}

= 2500 × 1.466

= 3,665.181

Rounding to nearest dollar

= $3665. 2

The current price of the item is $2500 and the price 10 years from today is $3665. 2.
