I = Prt
83.29 = 2500r(314/365) . . . . . substituting given values
r = 83.29*365/(2500*314) ≈ 3.8727%

The interest rate is about 3.9%.

Find the coefficient of the 4th term in expansion of (x +2 )^5
LuckyWell [14K]
(x + 2)^5=(x+2)^2\cdot{(x+2)^2}\cdot{(x+2)}\\\\(x+2)^5=(x^2+4x+4)\cdot{(x^2+4x+4)}\cdot(x+2)

(x+2)^5=(x^4+8x^3+24x^2+32x+16)\cdot(x+2)

(x+2)^5=x^5+10x^4+40x^3+80x^2+80x+32

Given: △ABC is equilateral, △ADC is isosceles,
KonstantinChe [14]

Answer:


Step-by-step explanation:

Since ABC is an equilateral triangle, thus AB=BC=AC=x, therefore

The perimeter of ΔABC=36

⇒AB+BC+AC=36

⇒x+x+x=36

⇒3x=36

⇒x=12

Thus, AB=BC=AC=12.

Now, Since ΔADC is isosceles triangle, therefore AD=DC=y.

Perimeter of ΔADC=40

⇒AD+DC+CA=40

⇒x+y+y=40

⇒12+2y=40

⇒2y=28

⇒y=14

Therefore, AD=DC=14

Thus, Length of sides of ΔABC are AB=BC=AC=12 and Length of sides of ΔADC are AD=DC=14.

The length of a rectangle is three times its width. The perimeter of the rectangle is at most 112cm. Which inequality models the
miss Akunina [59]

Answer: w ≤ 14 cm , L ≤ 42 cm

<u>Step-by-step explanation:</u>

width (w): w

Length(L): 3w

Perimeter (P) = 2w + 2L

P ≤ 112

 2w +   2L   ≤ 112

2(w) + 2(3w) ≤ 112

 2w +   6w   ≤ 112

       8w        ≤ 112

         w        ≤ 14

Write an equation to make the number "24" using all the numbers 5,4,2,2 and +, -, x and ÷.
Snezhnost [94]

Answer: See explanation

Step-by-step explanation:

We are given the numbers 5,4,2, and 2 and told to make an equation from it and get a final answer as 24. This will be:

= 5 × 4 + 2 + 2

= 20 + 2 + 2

= 24.

Since we have gotten a final answer of 24, the equation is solved.
