Answer:

31.8%

Step-by-step explanation:

The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.

I = PRT

5720 = (1200)(R)(15)

5720 = 18,000R

R = 0.3177777, rounded to 31.8%

Answer:

32%

Step-by-step explanation:

5720/15=381.33 interest per year

principal x interest rate = interest per year

1200 x interest rate =381.33

interest rate = 381.33/1200

interest rate = 32%

Given: Triangle ACD is isosceles; <1 is congruent to <3 Prove: Segment AB || Segment CD
julsineya [31]

Answer:

Segment AB || Segment CD

Step-by-step explanation:

Two lines are said to be parallel (||) if they do not meet, even when extended to infinity.

Given: <1 ≅ <3, ΔACD is an isosceles triangle.

Proof: Segment AB || Segment CD

From the diagram given,

AC ≅ AD (side property of isosceles triangle)

<3 = <4 (base angle property of an isosceles triangle)

<1 = <4 (alternate angle property)

Therefore, segment AB is parallel to segment CD.

factor: (x-16)(x+4)=0
by the zero product theorem,
x-16=0 or x+4=0
=> 
x=16 or x=-4

if you add 2 squares to the right side how many circles would you have to add to the right side to keep it balanced? please help
telo118 [61]

Answer:

  4 circles

Step-by-step explanation:

If you subract 3 squares from both sides, you end with 2 circles on the left and one square on the right. That is, 2 circles balance 1 square.

If you add 2 squares on the right, you need to add 2×2 = 4 circles on the left to balance them.
