First find a common denominator

1/16(2/2) = 2/32

9/32 - 2/32 = 7/32

7/32 is your answer

hope this helps

To start off this problem, you must change each of the fractions to their least common denominator. Between 32 and 16, the number we shall use is 32. Therefore, nothing needs to be changed for the  first fraction, but the second fraction needs to have a 32 at the bottom. So, you must multiply the denominator numerator by 2 (giving you the new, equivalent fraction of 2/32).

Now, all you have to do is subtract the fractions. Since the denominators are the same, all you have to do is 9 minus 2, which equals 7 over 32 (or 7/32) as your final answers. Typically, you would simplify the fraction after this, but in this case, it is not necessary due to the fact that it is in simplest form already. I hope this helps!

If the second hand of a clock has a length of 10 cm, find the distance the tip of the second hand travels in 45 seconds. Give an
UkoKoshka [18]

The distance traveled by the second hand of the clock is 0.471 m.

<h3 />

To calculate the distance the tip of the second hand of the clock travel in 45 seconds, we use the formula below.

<h3>Formula:</h3>
  • L = 2πr∅/360.................. Equation 1

<h3> Where: </h3>
  • L = distance traveled by the tip of the second hand.
  • r = Length of the second hand
  • ∅ = angle formed by the second hand of the clock
  • π = pie

From the question,

<h3>Given:</h3>
  • r = 10 cm = 0.1 m
  • ∅ = (360×45/60) =  270°
  • π = 3.14

Substitute these values into equation 1

  • L = 0.1×2×270×3.14/360
  • L = 0.471 cm.

Hence, The distance traveled by the second hand of the clock is 0.471 m

WILL GIVE BRAINLIEST THANKS AND 5 STARS FOR CORRECT ANSWER Desmond ran a lemonade stand in front of his house for the fans walki
Fiesta28 [93]

Answer:

56

Step-by-step explanation:

First, convert the 70% so that we can use it with the 80 cups. To do this, convert the percent to a decimal by moving the decimal 2 spaces to the left:

70% → 70.00 → 0.70 → 0.7

70% percent can be seen as 0.7. Multiply this by 80:

80*0.7=56

So, 70% of 80 is 56. Desmond sold 56 cups on the second Saturday.

:Done

An angle measures 72 degrees more than the measure of its complementary angle what is the measure of each angle
labwork [276]

Good evening

Answer:

<h2>measure of Angle 1 = 81°</h2><h2>Measure of angle 2 = 9°</h2>

Step-by-step explanation:

we need to solve this system

x + y = 90 (1)

x = y + 72 (2)

If we substitute x by y+72 into the equation (1) we will get

(y+72) + y = 90 ⇔ 2y + 72 = 90 ⇔ 2y = 90 - 72 = 18 ⇔ y = 9

then x = 90 - 9 = 81
