Answer:
There are 180 degrees in a triangle so it is 80 degrees
28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
Answer:
9 labours
Step-by-step explanation:
In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.
In indirect proportion, if one quantity increases, the other decreases and vice versa.
As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.
6 labours => 12 days
x labours => 8 days
Since its an inverse proprotion, multiply 6 with 12, and x with 8.
8x = 6 × 12
x =
∴ x = <u>9 labours</u>
Answer:240 square feet
Step-by-step explanation:
1/36 because you have 36 different possibilities when rolling it twice and getting and a 4 then a 6 is only 1 possibility out of the 36
1/4 because there is 3/6 chance on one roll and second roll
We said with 2 rolls there is 36 possibility (6x6)
So 3x3=9 which the amount of possibility to get a even number
9/36 simplify is 1/4 (divided by 9 the top and bottom)
Hope this helps!
