Answer:
37ft³
Step-by-step explanation:
Volume of the fish tank = length × width × height = 5ft × 3ft × 3ft = 45ft³
Volume of the cubic stone = length × length × length = (2ft)³ = 8ft³
Volume of the water = volume of the fish tank - volume of the cubic stone
i.e Volume of the water = 45ft³ - 8ft³ = 37ft³
*The side with the middle length is 12cm, therefore BC must be 12 cm

BC:AC:AB
4 : 3 : 5
</span>-----------------------------------------------------------
<span>Find 1 share
</span>-----------------------------------------------------------<span>
Given that BC = 12 cm
4 shares = 12 cm
1 share = 12 ÷ 4 = 3cm
</span>-----------------------------------------------------------
Find AC (4 shares)
-----------------------------------------------------------<span>
3 shares = 3 x 3 = 9 cm
BC = 9cm
</span>-----------------------------------------------------------
<span>Find AB (5 shares)
</span>-----------------------------------------------------------<span>
5 shares = 5 x 3 = 15cm
AB = 15cm

BC : AC : AB
12cm : 9cm : 15cm<span>

<span>12 + 9 + 15 = 36cm
</span>------------------------------------------------------------------
<span>Answer: The perimeter is 36cm

<span>Area
</span>------------------------------------------------------------------
1/2 x 9 x 12 = 54cm²<span>
</span>------------------------------------------------------------------
Answer: Area = 54cm²

Given that the biggest ratio is AB
</span>⇒AB is the hypotenuse
AB = 15 cm

Answer:
3, 5, 7
Step-by-step explanation:
As per triangle inequality theorem:
- <em>Any side of a triangle must be shorter than the other two sides added together</em>
Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5
- Then 1+3< 5 and it is against the above rule, so this is not correct
The next triple is: 3, 5 and 7
- Then 3+ 5 > 7 and it is correct
So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle
Answer:
Step-by-step explanation:
you multiply it with 100
0.23 x 100 = 23%
