Can anyone be nice and help a girl out. please i need help.
Nuetrik [128]

Answer:

Step-by-step explanation:

So when we solve the inequality:

2(x - 2) >_ 2

x - 2 >_  1 (divided 2 from both sides)

x >_ 3 (added 2 to both sides)

So with our final equation, we can work out that the answer is b, but d is also correct so I'm assuming that the inequality needs to be represented on a number line as hey usually are.

Hope this helps,

A cubed-shaped box has its side lengths decreased by 3 cm, when this happens, the volume decreases by 1385cm^3. What is the side
mixer [17]

Answer:

Step-by-step explanation:

let side of cube=x cm

volume=x³ cm³

again side=(x-3) cm

volume=(x-3)³ cm³

x³-(x-3)³=1385

(a³-b³)=(a-b)(a²+ab+b²)

(x-x+3){x²+x(x-3)+(x-3)²}=1385

3(x^2+x²-3x+x²-6x+9)=1385

3(3x²-9x+9)=1385

9x²-27x+27=1385

9x²-27x+27-1385=0

9x²-27x-1358=0

x=\frac{27\pm\sqrt{(-27)^2-4*9*(-1358)} }{2*9} \\x=\frac{27\pm\sqrt{729+48888} }{18} \\or~x=\frac{27\pm\sqrt{49617} }{18} \\or~x=\frac{27\pm 222.749}{18} \\taking positive side only as negative sign gives negative length.\\or~x=\frac{27+222.749}{18} \\or~x\approx13.87

What is the annual interest rate for 12% compounded quarterly for 6 years?
mamaluj [8]

COMPOUND INTEREST

Compounded Calculation Interest Rate For One Period

Semiannually, every 6 months, every half of a year (.06)/2 0.03

Annually, every year .06 .06

6% means 6 percent (from Medieval Latin for per centum, meaning "among 100"). 6% means 6 among 100, thus 6/100 as a fraction and .06 as a decimal

Does this help you?
