Answer:

Angle 1: 55

Angle 2: 110

Angle 3: 15

Step-by-step explanation:

Angle 1: x

Angle 2: 2x

Angle 3: x-40

The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).

harina [27]

Answer:

The balance after 1 is $7070.35.

Step-by-step explanation:

Compound continuous formula:

A=Pe^{rt}

A=The final balance

P=Principal

r= interest rate.

Jason deposited $700.00 as principal for 1 year at a rate 1%, compounded continuously.

Here A=$700.00, t= 1 year, r=1%=0.01

A=7000e^{0.01 \times 1}

   =$7070.35

The balance after 1 is $7070.35.

The answer is NOT.. C. please help .
Svetach [21]

Answer:

Option B

Step-by-step explanation:

First term of the given arithmetic sequence 'a' = -3

Common difference in each successive term 'd' = -8 - (-3)

                                                                             d = -5

Explicit formula for an arithmetic sequence will be,

A_n=a+(n-1)d

Here, n = number of term

A_n = nth term of the sequence

A_n=(-3)+(n-1)(-5)

For n = 23,

A_{23} = -3 + (23 - 1)(-5)

     = -3 - 110

     = -113

Option B is the answer.
