Answer:
2764.8cm³
Step-by-step explanation:
Looking at the diagram, the barn is a combination of 2 geometric shapes, a cuboid and Triangular prism
Step 1
Find the volume of the cuboid
Volume of the cuboid = Length × Width × Height
Length = 10cm
Width = 20.4cm
Height = 11.2cm
Volume = 10cm × 20.4cm × 11.2cm
Volume = 2284.8cm³
Step 2
Volume of Triangular prism = 1/2 × base × height × length
= 1/2 × 8 × 12 × 10
= 480cm³
Total volume = 2284.8cm³ + 480cm³
= 2764.8cm³
Answer:
Step-by-step explanation:
Total weight of all of the filled jars with jam = 211.2 ounces
When empty, each jar weighs 1.2 ounces
Total weight of 2 dozens of empty jar = 24 × 1.2 ounces
= 28.8 ounces
Total weight of jam in 2 dozens jar = Total weight of all of the filled jars with jam - Total weight of 2 dozens of empty jar
= 211.2 ounces - 28.8 ounces
= 182.4 ounces
The weight of jam in one jar = 182.4 ounces / 24 jars
= 7.6 ounces
The weight of jam in one jar = 7.6 ounces

Answer:
6 and -8
Step-by-step explanation:
Solve:
xy = 48
x + y = -2
You can say y = -2-x = -(x+2) and then substitute that in the first:
-x(x+2) = 48
-x² -2x - 48 = 0
x² + 2x + 48 = 0
Quadratic formula can do the rest if you don't "see" the factorization.
Answer:
-30
Step-by-step explanation:
move and divide -3/5 to the right side
-3/5x = 18
x=18÷(-3/5)
x= -30
