Answer: Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 30 milliliters
Step-by-step explanation:
Given: Total solution required = 130 milliliters
Let x = Amount of 35% solution (in milliliters).
Then, Amount of 87% solution required = 130 - x
As per given,
Concentration = 0.35x +0.87(130-x)=0.47(130)
Hence, Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 130-100 milliliters =30 milliliters

Answer is r=8
Area of the figure is 102 cm²
Step-by-step explanation:
- Step 1: Find the area of the square with side = 6 cm.
Area of the square = (side)² = 6² = 36 cm²
- Step 2: Find the area of the trapezoid.
Length of parallel side 1 = 7 cm
Length of parallel side 2 = 21 - 6 = 15 cm
Height = 6 cm
⇒ Area of the trapezoid = 1/2 × (Sum of parallel sides) × height
= 1/2 × (7 + 15) × 6
= 1/2 × 22 × 6 = 66 cm²
- Step 3: Find the area of the figure.
Area of the figure = Area of the square + Area of the trapezoid
= 36 + 66 = 102 cm²
Answer:
No
Step-by-step explanation:
We know that the 3-4-5 and 9-12-15 right triangles are similar. If you add 6 units to the length of each side of both of these triangles, you obtain 9-10-11 and 15-18-21 triangles, which are not similar since 9/15 is not equal to 10/18.
