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.

On her last credit card bill, Linda paid a variable rate of 1.8 percent on the first $200 and 1.2 percent on

dybincka [34]

Interest paid by Linda is equal to $4.272 approximately equal to $4.27.

<u> Solution: </u>

Given that

Rate of interest on first $200 = 1.8%

Rate of interest on any amount over $200 = 1.2%

Unpaid balance amount of Linda’s credit card bill = $256

Need to calculate interest paid by her on $256.

Unpaid balance = $256

=$200 + 56

Amount over $200 = 56

Interest paid on first $200 = 1.8% of 200

= 0.018 x 200 = $3.6

Interest paid on amount over $200 that is $56 = 1.2% of 56

= 0.012 x 56 = $0.672

So total interest paid on $256 = 3.6 + 0.672 = $4.272.

Hence interest paid by Linda is equal to $4.272 approximately equal to $4.27.

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent

Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches
