Answer:

= 5/3 * pi  inches

  or approximately 5.235987756 inches

Step-by-step explanation:

The formula for arc length = r * theta  where theta is in radians

arc length = 10 * pi/6

                 = 10/6 * pi

                = 5/3 * pi

                or approximately 5.235987756 inches

Answer: 5.23 inches

Step-by-step explanation:

Let the length of the arc intersected by a central angle x be l.

Given:- Central anglex=\frac{\pi}{6}\text{ radians}

Radius r= 10 inches

We know that ,

l=x\ r\\\\\Rightarrow\ l=\frac{\pi}{6}\times10\\\\\Rightarrow\ l=\frac{3.14\times10}{6}= 5.2333333333\approx5.23\text{ inches}

Thus, the length of the arc of a central angle \frac{\pi}{6}\text{ radians} is 5.23 inches.

A piggy bank contains a total of 84 coins in nickels and quarters worth $12.80.
Kitty [74]

Let's make a system of equations to solve for this:

n + q = 84

0.05n + 0.25q = 12.80

where n = nickels and q = quarters.

---

Solve for n in the first equation by subtracting q from both sides.

n = 84 - q

---

Plug n into the second equation.

0.05(84 - q) + 0.25q = 12.80

Distribute 0.05 inside the parentheses.

4.2 - 0.05q + 0.25q = 12.80

Combine like terms.

4.2 + 0.2q = 12.80

Subtract 4.2 from both sides.

0.2q = 8.6

Divide both sides by 0.2.

q = 43

---

Plug 43 for q in the first equation.

n + (43) = 84

Subtract 43 from both sides.

n = 41

---

There are 41 nickels and 43 quarters in the piggy bank. ✅

A restaurant needs pound 7/8 of cinnamon. The price of cinnamon is $20 per pound. How much does the restaurant spend on cinnamon
Lorico [155]

Answer:

$17.50

Step-by-step explanation:

Multiply 7/8 by 20/1, to find 7/8 of $20.00.

7/8 × 20/1 = 140/8

140 ÷ 8 = 17.5

Once you convert to money, this is $17.50.
