Answer:
Step-by-step explanation:
We know that the sum of Angle S and Angle T is 120. So:
The measure of Angle S is (4x + 30).
And the measure of Angle T is (30).
We want to find the value of <em>x</em>.
By substitution:
Combine like terms:
Subtract 60 from both sides:
Divide both sides by 4:
Hence, the value of <em>x </em>is 15.
To round $2.99 to the nearest cent we will look at the digit in the hundredths place which in this case it the 2nd 9 (2.99). If this number is 5 or higher we will round up and if it is less than 5 we will leave it. Since this is more than 5 we will round up to the nearest cent which would make it .00 which would make the number $2.99 rounded to the nearest cent $3.00.
Hope I helped ya!! xD

Answer:
If there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct
Step-by-step explanation:
There are 5 persons and at a time only 3 can be arranged.
The total number of arrangements = nPr = n!/(n-r)!
Here n = 5 and r = 3
nPr = n!/(n-r)!
nPr = 5!(5-3)!
nPr = 5!/2!
nPr = 5*4*3*2!/2!
nPr = 5*4*3
nPr = 60
So, if there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct.
