Answer:
44 units²
Step-by-step explanation:
For triangles: (bases and heights of both triangles are equal)
Base = 4 units, height = 3 units
For trapezoid:
Base 1 = 5 units, base 2 = 3 units, height = 8 units
Area of figure = Area of two triangles + Area of trapezoid
= 2 *1/2 * base * height + 1/2(base 1+ base 2) *height
=4*3 + 1/2(5+3)*8
= 12 + 8*4
= 12 + 32
= 44 units²
Answer:
Angle ∠A = 40.664°
Step-by-step explanation:
Law of Cosine
Answer:
Step-by-step explanation:
- Let (applicable to all three lines below)
- Hard candy = x kg with price $1.60/kg
- Gummy worms = y kg with price $2.20/kg
- Total weight = 50 kg with mixed price $1.75/kg
<u>Required equations:</u>
- x + y = 50 total weight
- 1.60x + 2.20y = 50*1.75 total price
=========================================
<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>
<u>Simplify the second equation and solve by substitution x = 50 - y:</u>
- 1.6(50 - y) + 2.2y = 87.5
- 80 - 1.6y +2.2y = 87.5
- 0.6y = 7.5
- y = 7.5/0.6
- y = 12.5
<u>Find the value of x:</u>
<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg
