Answer:
32 cm^3
Step-by-step explanation:
The cube is 4 across by 4 high by 2 wide
4*4*2 = 32 cm^3
Answer:
width = 5cm
length = 10cm
Step-by-step explanation:
1. the ratio is 1:5 so 50 metres in real life is 10 centimetres on paper so length = 10 cm
2. 25 metres in real life is 5 centimetres on paper so width = 5 cm
Answer:
x = 139º
Step-by-step explanation:
A line = 180º
180º - 41 º = 139º
Answer:
A
Step-by-step explanation:
8 gallons of regular gas with 10% and 2 gallons with 85%
8 x 10 =80%
2 x 85 =170%
170+80=250%
10 gallons each with 100%, so 10 x 100 =1000%
250% of 1000% = 1/4 or 25% ethanol
Hope this helps!
Step-by-step explanation:
what is the main condition the lengths of the sides of a right-angled triangle have to fulfill ?
Pythagoras !
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle), a and b are the so-called legs (the sides enclosing the 90 degree angle).
only if there is a combination of the sides, for which the Pythagoras equation is true, do we have a right-angled triangle. otherwise not.
we also know CA = 18 - 7 - 3 = 8 cm
so, let's try
8² = 7² + 3²
64 = 49 + 9 = 58 wrong
7² = 8² + 3²
49 = 64 + 9 = 73 wrong
3² = 8² + 7²
9 = 64 + 49 = 113 wrong
so, there is no combination, where the Pythagoras equation is true, so it is NOT a right-angled triangle.
