If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD? Round your answ
kondaur [170]

Answer:

1.17

Step-by-step explanation:

(MUCH BETTER!)

From the definition of the sin of an angle, you know:

sin(45°) = AC/AB = 4/AB   ⇒   AB = 4/sin(45°) ≈ 5.6569

sin(63°) = AC/AD = 4/AD   ⇒   AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is:

AB -AD = 5.6569 -4.4893 = 1.1676

AB -AD ≈ 1.17 units

Sorry this took me so long to answer!

William buys two bags of peaches and three bags of apricots for $17. Sylvia buys four bags of peaches and two bags of apricots f
Rus_ich [418]

Answer: One bag of peaches : $22

Step-by-step explanation:

Hi, to answer this question we have to write an equation for William and Sylvia.

  • <em>William: 2 p + 3 a = 17 </em>
  • <em>Silvia: 4p + 2 a =22 </em>

Where:

p = price of one bag of peaches

a= price of one bag of apricots

Solving for "a" in William's equation:

2p +3a =17

3a = 17-2p

a = (17-2p)/3

a= 17/3 -2/3 p

Replacing "a" in Silvia's equation

4p + 2 a =22

4p + 2 (17/3 -2/3p) =22

4p +34/3-4/3p =22

4p-4/3p =22-34/3

8/3 p =32/3

p =32/3 ÷8/3

p=4
