Bogdan [553]

Answer:

Step-by-step explanation:

account balance on compound interest = principal amount (1+rate/100)^time

here there are t years so toat months are 12t and ad interest is after each 4 months so time is 12t/4 =3t

now total balance = 3545(1.045)^3t

here 3545 is principal amount , rate is( 1.045-1)×100 =4.5% per 4 months and 3t is time so clearly 3t or 3 is a growth factor hence option A

A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the

Goryan [66]

Answer:

<em>The perimeter of the pizza slice is 20.1 cm</em>

Step-by-step explanation:

<u>Perimeter of a Sector of a Circle</u>

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

$\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}$

The perimeter is:

$P = 7*\frac{5\pi}{18} + 2*7$

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm

What is the answer to-2x+5=-31

7nadin3 [17]

Answer:

x = 18

Step-by-step explanation:

Subtract 5 on both sides:

-2x + 5 =- -31

-5 -5

-2x = -36

Divide by -2 on both sides:

-2x = -36

/-2 /-2

x = 18
