Answer:

40.6 units

Step-by-step explanation:

Arc length is given by the formula ...

s = rθ

where θ is the measure of the central angle in radians.

There are 2π radians in a circle (360°), so π radians in 180°. That can be used to convert the central angle ADB to radians for use in the formula.

∠ADB = 360° -194° = 166°

∠ADB = 166° = (166/180)π radians = 83π/90 radians

Then the arc length AB is ...

length AB = (14)(83π/90) ≈ 40.561 units

The length of arc AB is about 40.6 units.

The Lone Star Shipping Company charges $14 plus $2 a pound to ship an overnight package. Discount Shipping Company charges $20 p

Ymorist [56]

Answer:

12 pound

Step-by-step explanation:

Let $x$ be the weight of the package.

For Lone Star Shipping, the cost will be:

$2x + 14$

For Discount Shipping Company, the cost will be:

$1.5x + 20$

We hence equate these two expressions equal to each other, since the cost should be same.

$2x + 14 = 1.5x + 20 \\2x - 1.5x = 20 -14\\0.5x = 6\\x = 6 \div 0.5\\x = 12$

Cody has $700 in a savings account that pays 4% simple interest. How much will he have in 1 year?

ladessa [460]

Answer:

$ 728

Step-by-step explanation:

Amount of Money Cody has = $700

Simple Interest = 4%

As it is know that interest is always given on annually basis so

Amount of profit he have in one year = Money he have right now * interest

=700 * 4%

= $700 * \frac{4}{100}$

= $ 28

After one year he will have = total money at that time + Profit

= 700 + 28

= $ 728
