What is the length of AD? Express the answer in terms of Pie.

Mathematics
1 answer:
Ostrovityanka [42]3 years ago
4 0

Answer:

3 pi

Step-by-step explanation:

We already know that the sum of the angles adds up to 360.

Therefore we get 73+ 104+ 43 + x = 360, where x = 140

arc length = \frac{angle}{360} * (2\pi r)

were the angle is 140 and r = 4. The radius was given.

Hope this helps.

Destiny and Guadalupe are shopping. Destiny buys 2 pairs of pants and 6 bracelets and pays $178.Guadalupe buys 3 pairs of pants
ziro4ka [17]

For the entirety of this problem, p will represent a pair of pants and b will represent a bracelet.

Step 1) Set up equations for Destiny and Guadalupe

Destiny: 178 = 2p + 6b

Guadalupe: 155 = 3p + 2b

I will be using substitution to solve this problem, but elimination can also be used.

Step 2) Solve Destiny's equation for p

178 = 2p + 6b

178 - 6b = 2p

89 - 3b = p

Step 3) Substitute the found value of p from Destiny's equation into Guadalupe's equation and solve for b

155 = 3(89 - 3b) + 2b

155 = 267 - 9b + 2b

155 = 267 - 7b

-7b = -112

b = 16

Step 4) Use the value of b found in step 3, plug that back into our equation from step 2 and solve for p

89 - 3(16) = p

89 - 48 = p

p = 41

one pair of pants = $16

one bracelet = $41

Hope this helps!! :)

If 9% of a number equals 5, find 36% of that number.
lakkis [162]

Answer:

20

Step-by-step explanation:

  1. You can set this up in an algebraic equation:
  2. .09x=5  which translates to 9% times a variable or unknown number equals 5
  3. Divide both sides by .09 which turns to 55.5
  4. Multiply by .36 to find 36% of that number which equals 20
