Answer:
x=4
Step-by-step explanation:
Step 1:-
given the lengths of two sides of a right angle are represented by 2x and 3(x+1) and longest side is 17 units.
AB = 2x and BC = 3(x+1) and longest side AC= 17
by using Pythagoras theorem
step 2:-
The hypotenuse is longest side is AC = 17 units
(17)^2 = 4x^2 +9(X+1)^2
on simplification, we will use formula
289 = 4x^2 +9(x^2+2x+1)
finding factors 70 X 52 = 3640
Taking common , we get
13x(x-4)+70(x-4)=0
x-4=0 and 13x+70=0
x=4 and
x=4 and
we can not choose negative value so x value is 4
Final answer:- x = 4
verification:-
289 = 4(4)^2+9(4+1)^2
289 = 64 +9(25)
289=289
Answer:
x = 4
Step-by-step explanation:
The length of two legs of a right angle triangle are 2x and 3(x+1).
The length of longest side is 17 units. It means measure of hypotenuse is 17 units.
According to the pythagoras theorem,
On splitting the middle terms we get
Using zero product property we get
The value of x can not be a negaive number, because for negative value of x the value of 2x is negative and side can not be negative.
Therefore, the value of x is 4.
The approximations of 649,418 are as follows;
Nearest ten = 649,420
Nearest hundred = 649,400
Nearest thousand = 649000
Nearest ten thousand = 650000
Nearest hundred thousand = 600000
Units digit is 8
Tens digit is 1
Hundreds digit is 4
Thousands digit is 9
Ten thousands digit 4
Hundred thousands digit is 6
1) Approximating the nearest tenmeans if the units digit is 5 or more than 5, we add 1 to the tens digit. In this case, we will have; 649,420.
2) Approximating thenearest hundred means if the tens digit is 5 or more than 5, we add 1 to the hundreds digit otherwise we leave it and make every other term to its' right 0 to get; 649,400.
3) Approximating thenearest thousand means if the hundreds digit is 5 or more than 5, we add 1 to the thousands digit otherwise we leave it and make every other term to its's right 0 to get; 649,000.
4) Approximating thenearest ten thousand means if the thousands digit is 5 or more than 5, we add 1 to the ten thousand digit to get 650,000.
5) Approximating the nearest hundred thousandmeans if the ten thousand digit is 5 or more than 5, we add 1 to the hundred thousand digit otherwise we leave it and make every other term 0 to get 600,000.

Answer: In decimal , it will be expressed as 0.6 .
Step-by-step explanation:
Since we have given that
Total number of students = 15
Number of students names as their favourite class = 9
First we write as a fraction, which is given by
Now , we will change it into decimal form using division, so it will be given by
Hence, our answer is 0.6.
