The volume of the box when it's filled to 3 inches deep is 12×8×3 = 288 in³
The box is filled up to 1.5 inches from the top, that means the box is filled only
3-1.5 = 1.5 inches deep
The volume of the box when it's filled to 1.5 inches deep is 12×8×1.5 = 144 in³
The number of flours saved is 288 - 144 = 144 in³
1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
last one is the solution u should choose
Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 
and ( )² = 12
2² + (
)² = 4 + 8 = 12
Thus the triangle is right → C
