Answer:
<u>70 square units</u>
Step-by-step explanation:
<em>I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached. </em>
The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:
Area of Arrow = Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 * base * height
Base is 12 units
Height is 7 units, so
Area of Triangle = 0.5 * 12 * 7 = 42
Now,
Area of Rectangle = length * height
Length is 7
Height is 4
Area of Rectangle = 7 * 4 = 28
<u>Area of Arrow = 42 + 28 = 70 square units</u>
Number of lilies used= 30 lilies
Number of roses used= 78 roses
To make the six identical arrangements:
We need to divide lilies into six equal parts, as well as number of roses in six equal parts.
I=Number of lilies in each arrangement = 
r=Number of roses in each arrangement = 
Total number of flowers in arrangement (I + r)= 5 Lilies + 13 Roses=18 (Flowers)
The relationship between l, the number of lilies, and r, the number of roses:
→ 5 I = 13 r
Answer How many liters of a 20% acid solution should be mixed with 30 liters of 50% acid solution in order to obtain a 40% solution. ... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That is 18 liters pure acid That is 45 liters solution *0.45 pure acid=18 liters.
As more pure acid is added, the concentration of acid approaches 0.
Inequality:
