How much would your total be if you bought 5 lbs of apples<br> and 4 lbs of oranges?

Nana76 [90]

Answer:

So apples would cost $2.95 and oranges would cost $1.92 then you would add those two together to get $4.87.

Step-by-step explanation:

Apples you would do 0.52×5 and get $2.95 and for oranges you would do 0.48×4 to get $1.92, then you just add the two numbers together.

PLEASE HELP!!!<br> Which expressions simplify to a rational answer? Select each correct answer.

Bond [772]

ANSWER

The first three expressions will simplify to a rational answer.

EXPLANATION

Let us simplify the expressions then we can see which of them are rational.

$7\sqrt{3} \times \sqrt{3}$

We multiply out the roots to get

$7\sqrt{3} \times \sqrt{3}=7 \times (\sqrt{3})^2$

This simplifies to

$7\sqrt{3} \times \sqrt{3}=7 \times 3$

$7\sqrt{3} \times \sqrt{3}=21$

This is a rational number hence the answer is rational.

$\sqrt{5} \times \sqrt{5}=(\sqrt{5})^2$

$\sqrt{5} \times \sqrt{5}=5$

This is also a rational solution.

$2\sqrt{9} \times \sqrt{4}=2\times3\times2$

$2\sqrt{9} \times \sqrt{4}=12$

This one too is a rational solution.

$\sqrt{3} \times \sqrt{16}=\sqrt{3}\times4$

$\sqrt{3} \times \sqrt{16}=4\sqrt{3}$

This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.

Consider this cone with a diameter of 19 cm. A cone with diameter 19 centimeters and slant height of 31 centimeters. Use the dro

Anestetic [448]

Answer:

1) Radius of the cone = 9.5 cm

2) BA = 90.25 π cm²

3) SA = 384.7 π cm²

Step-by-step explanation:

1) Radius of the cone = 9.5 cm

2) Base Area of the cone =

BA = (π)(9.5)²

BA = 90.25 π cm²

3) Surface Area of Cone =

SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)

SA = 9.5π(9.5 + 31)

SA = 9.5π(40.5)

SA = 384.7 π cm²
