What is the approximate length of RP? Round to the nearest tenth. 5. 6 units 6. 1 units 8. 3 units 9. 8 units.
kirza4 [7]

The apporoximate length of the RP is 6.1 units, the correct option is B.

<h3>What is Pythagoras theorem?</h3>

The Pythagoras theorem states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle.

Given

QR is the tangent to circle P at point Q.

QP = 3 units and QR = 5,.3 units

The length of the RP is given by;

\rm RP=\sqrt{QP^2+QR^2} \\\\RP=\sqrt{3^2+5.3^2}\\\\ RP=\sqrt{9+28.09} \\\\RP=\sqrt{37.09}\\\\RP= 6.1 \ units

Hence, the apporoximate length of the RP is 6.1 units.

5x + 5 = x + 45<br><br> PLEASE HELP
Ostrovityanka [42]
5x+5=x+45

We'd rather not have x on both sides of the equation when trying to solve this. To eliminate the x on the right side, subtract both sides by x.

5x+5-x=x+45-x
4x+5=45

Let's get eliminate the "5" on the left side. Subtract both sides by 5.

4x+5-5=45-5
4x=40

To finish this, divide both sides by 4.

4x \div 4=40 \div 4
x=10

That is the answer. Hope this helps! :)

mixas84 [53]
6t-10is the awsner. If s is the number of nautical miles separating the ships, express s in terms of t(the number of hours after 12 noon). I formed the equation s squared to the second power equals (12t) squard to the second power + (10 - 16) squared to the second power
