Answer:
4√3
Step-by-step explanation:
This is a right triangle. When two sides are given in a right triangle, we need to use the Pythagorean Theorem to solve for the third side.
Pythagorean Theorem: a² + b² = c²
The a here is 11, while the b is x. The c is always the hypotenuse (the longest side), which is 13.
Now we substitute:
11² + x² = 13²
121 + x² = 169
-121 -121
x² = 48
√x² = √48
x = √48 <-- We can simplify that.
√48 = 12 * 4 = 3 * 4 * 4 = 4√3
That is a decay equation because .150 is less than 1.
Answer:
x = 2
Step-by-step explanation:
3(10 - 2x) = 18
Divide both sides by 3.
10 - 2x = 6
Subtract 10 from both sides.
-2x = -4
Divide both sides by -2.
x = 2
Hello there.
<span>1. Lucy has a jewelry business. To make a certain necklace, she spends $3.38 on materials and $5.57 on labor. She then sells the necklace for $15.99. Lucy’s profit on the necklace is equal to the sale price minus the cost of materials and labor.
</span><span>
(a)How much profit does Lucy earn when she sells a necklace? What fraction of the sale price of the necklace is profit? Record your answer as a fraction using whole numbers.
</span>the fraction of the sale price of this necklace would be (704/1599).
<span>c) Lucy collected $223.86 selling necklaces at a craft fair. How many necklaces did Lucy sell? How much profit did she earn?
</span>223.86/15.99=14 necklaces. 14(7.04)=$98.56 of profit.
