Mathematics

Mila [183]2 years ago

Answer:

  18π cm² ≈ 56.5 cm²

Step-by-step explanation:

The area of the sector can be found using an appropriate area formula.

<h3>Sector area</h3>

When the sector central angle is given in radians, the formula for the area of that sector is ...

  A = 1/2r²θ . . . . . . where θ is the central angle, and r is the radius

When the angle is in degrees, the formula will include a factor to convert it to radians:

  A = 1/2r²θ(π/180) . . . . where angle θ is in degrees

  A = (πθ/360)r² . . . . simplified slightly

The figure shows r=9 cm, and θ=80°. Using these values in the formula gives an area of ...

  A = π(80/360)(9 cm)² = 18π cm² ≈ 56.5 cm²

Natali [406]

The amount that the credit union will finance is $24169.60

We have given that the cost of the car is $22,346. 16

and the credit union required 10% down payment

and sale tax=7.6%

The license and title charges are $125. 13.

We have to determine that the  amount that the credit union will

finance Now  we have sale tax 7.6% for $22,346. 16

Therefore, we get

\frac{7.6}{100} \times 22,346. 16=1698.31

<h3>What is the amount that the credit union finance ?</h3>

credit union finance=cost of car+sales tax+the license and title  charges.

=22346.16+1698.31+12.13\\=24169.60

Therefore, the amount that the credit union will finance is $24169.60

A 1-liter bottle of orange juice used to cost $2.85 at a food market. Its price has increased; the new price is 110 percent of t
AfilCa [17]

Answer:

The new price of the bottle is $ 3.14.

Step-by-step explanation:

Given,

Original price of 1-liter bottle of orange juice  = $ 2.85,

Since,  the new price is 110 percent of the original price.

Thus, the new price of the bottle = 110 % of the $ 2.85

=\frac{110\times 2.85}{100}

=\frac{313.5}{100}

=3.135\approx 3.14

Hence, the new price of the bottle is $ 3.14.
