Answer:
45
Step-by-step explanation:
divide 300 by 100 then multiply it by 15 to find how many people makes 15% of 300
300 ÷ 100 = 3 ➡ 3×15 = 45
A. 8.53 units is the length of the straight which is perpendicular to the straight line CD
The easiest way is to make sure the fractions have the same denominators and are improper fractions. So another way to write it is : 4/15 + 5/15. Then you can add the numerators together making the numerator 9. The denominator will stay the same.
9/15
Since it is not simplified, divide both sides by three:
3/5
Answer:
The nth term will be;
Tn = Tn-1 + 6(n-2) + 11
Step-by-step explanation:
Here, we are to find the nth term of the given equation
Firstly, we need to notice a pattern
What difference do we notice between the terms?
That would be;
16-5 = 11
33-16 = 17
56-33 = 23
next would be 29 + 56 = 85
afterwards; 85 + 35 = 120
So the pattern here is that we shall add 6 to the last common difference between the two preceding term to get the succeeding term
So what’s the nth term here?
Tn = Tn-1 + 6(n-2) + 11
So for example, the 5th term will be;
T5 = T5 + 6(5-2) + 11
T5= 56 + 18 + 11 = 85
While the 4th term will be
T4 = 33 + 6(4-2) + 11
T4 = 33 + 12 + 11 = 33 + 23 = 56
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
