Answer: -3
Step-by-step explanation:
-4 +
can be written as x
which is the same as 2
Also , can be written as x , which is the same as 5
Substituting into the main question , we have
-4 (2 ) + 5
= -8 + 5
= -3
Answer:
The total number of ways in which three winners can come in is 990 ways.
Step-by-step explanation:
It is provides that the number of automobiles entering the race is: <em>n</em> = 11.
It is also provided that there were no ties.
There are supposed to be three winners for the race.
- The number of ways the first winner can come in is: 11 ways.
- The number of ways the second winner can come in is: 10 ways.
- The number of ways the third winner can come in is: 9 ways.
Compute the total number of ways in which three winners can come in as follows:
Number of ways in which the first three finishers come in is
Thus, the total number of ways in which three winners can come in is 990 ways.
If cos θ = (-5/13), then θ should be in quadrant II or III. The given says sin θ < 0, so θ should be in quadrant III. In this case, tan <span>θ should be equal to number greater than zero. Hence we get sqrt of (13^2 - 5^2 ) equal to 12. tan </span><span> θ should be equal to A 12/5. </span>
Answer: Dimension of the field ratio is 2:1
Step-by-step explanation:
First, we make the units equal by converting kilometre to metre
1.2km to m, multiply by 1000
1.2km = 1.2 x 1000 = 1200 meters
Then, put in ratio
1200 : 600; find a common divisible number, which is 600.
Dimensionof the field ration is 2:1
