Answer:
Step-by-step explanation:
To the evaluate -5.3+7.9
We get
2.6
Therefore the error
=2.6-2.4
=0.2
Answer:
3
Step-by-step explanation:
Rewrite the logarithmic notation to index notation.
4^x=64
Change 64 to index notation
ie 64 = 4^3
Since the base is the same(4) cancel them out
You remain with x = 3
Answer:
18
Step-by-step explanation:
24=8×3
If F=24 when A=8 then F is directly proportional to A•3
A=π(10t)2=100πt2
B.
A=100×3.14×32=2826
Answer:
Two right angles = 180 degrees
Step-by-step explanation:
A right angle = 90 degrees
The sum of the interior angles of a triangle = 180 degrees
Two right angles (2 * 90) = 180
180 = 180
Therefore, the sum of the interior angles of any triangle is equal to two right angles.
