Answer:
I think it might be 2:5?
Step-by-step explanation:
Answer:9.22
First, 670 rounded to the nearest ten is:
670
Second, 72.7 rounded to 1DP is:
well, 72.7
a÷b is:
9.2159
9.22 (2 DP)
Answer:
Then it is just a matter of plugging in the values into the formula. For example, if one base is 6 cm long, the other is 10 cm long and the height is 4 cm, the area is then (6 + 10) / 2 x 4 = 16 / 2 x 4 = 8 x 4 = 32 cm 2 (32 square centimeters).

Answer:
SSS
Step-by-step explanation:
Two triangles are said to be congruent if all their three sides are equal and all of their three angles are equal. There are 5 ways of determining congruent triangle which are:
- SSS (side, side, side): This is when the two triangles have all three sides equal to each other.
- SAS (side, angle, side): This is when the two triangles have 2 equal sides and one included angle of both triangles are equal.
- ASA (angle, side, angle): This is when the two triangles have 2 equal angles and one included side of both triangles are equal.
- AAS (angle, angle, side): This is when the two triangles have 2 equal angles and one non included side of both triangles are equal.
- HL (hypotenuse, leg): The hypotenuse is the longest leg of a right angled triangle. If two triangles have equal hypotenuse and one equal leg, they are congruent.
Triangle ABC and triangle BCD are congruent because:
AB = CD, AC = BD and both triangles share the same side BC. That is they have three equal sides (SSS)
Answer:
The mass of the piece of granite with volume of 75 cm^3 is 202.5 grams.
Step-by-step explanation:
Let
m = the mass of a piece of granite whose volume is: 40 + 35 = 75 cm^3 (greater by 35 cm^3)
Since Density = Mass / Volume and we are talking about pieces of the same material (same density) we can write:
m/75 = 108/40
m = 202.5 g
