Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be
Which when you invert and multiply becomes
which finally becomes
Answer:
3/4 x 30 = 90/4
= 22.5 laps per hour
Step-by-step explanation:
Answer:
For this question, we can assume that the lines are parallel.
Step-by-step explanation:
This means that angle 1 is congruent to angle 11.
Afterwards, we know that angle 11 + angle 12 equal a straight line, or 180º.
If angle 11 is congruent to angle 1, that means measure angle 11 = 112º.
Then, we subtract 112 from 180 which would give us 68.
Therefore, the answer is 68º.
Answer:
129° and 37°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
∠ 1 is an exterior angle, thus
∠ 1 = 62° + 67° = 129°
(b)
∠ 1 + 115° = 152° ( subtract 115° from both sides )
∠ 1 = 37°
30x^2 - 5X^3 = 5*6*x^2 - 5*x^2*x = 5x^2( 6 - x ).
