Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture

13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd

total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³

so
0.69/3=0.23=23%

answer is D

GalinKa [24]

Answer:

13.29 square meters

Step-by-step explanation:

The two shorter sides of a right triangle have lengths of 9.88 meters and 2.69 meters

Two shorter sides are the base and the height of the right angle triangle

Area of the triangle is 1/2 times base times height

$area= \frac{1}{2} \cdot 9.88 \cdot 2.69$

Area of the triangle is 13.2886

13.29 square meters
