Answer:
140 degree
Step-by-step explanation:
Since the sum total of a polygon is 540 degree, simply subtracts from each degree of the other angles.
540 degree - 110 degree - 85 degree - 125 degree - 80 degree = 140 degree
Answer:
0.21
Step-by-step explanation:
For independent probalities, the chance of both things happening is their product. 0.3 * 0.7 = 0.21
All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)
Answer:
15 inches
Step-by-step explanation:
42 = 2L + 2(6)
first, we need to isolate L.
solve 2(6) to make this easier
42 = 2L + 12
42 - 12 = 2L + 12 - 12 ( this cancels out 12. )
30 = 2L
30 ÷ 2 = 2L ÷ 2 ( this cancels out 2. )
15 = L
We solve this the following way:
tie dyed shirts = x
white shirts = y
x = 3y
x + y = 196
3y + y = 196 (we substitute the x with the 3y in the main equation)
4y = 196 (divide this)
y =49
x = 147
The man sold 147 tie dyed shirts and 49 white shirts.
