The length of a rectangle is 9 inches more than twice it’s width. If the perimeter of the rectangle is 48 inches find its length
morpeh [17]

Answer:

Length=19 inches\\\\Width=5 inches

Step-by-step explanation:

Let the width of the rectangle be 'w' inches

length of the rectangle= (2w+9) inches

Perimeter of the rectangle= 48 inches

Perimeter of a rectangle= 2(Length+Width)

                      48=2((2w+9)+w)\\\\48=2(2w+9+w)\\\\48=2(3w+9)\\\\48/2=3w+9\\\\24=3w+9\\\\3w=24-9\\\\3w=15\\\\w=15/3\\\\w=5 inches

                     Width= 5 inches

Length=(2w+9)=2(5)+9=19 inches

Length=19 inches\\\\Width=5 inches

Which linear inequality is represented by the graph? O y<2/3x+3 (A)
KATRIN_1 [288]

Answer:

C y>2/3x+3

Step-by-step explanation:

Use y=mx+b format. The B is the y-intercept. From the y-intercept (3), go up two then to the right 3. That gives you the slope, or mx which is 2/3. The area shaded is above so it would be the greater than symbol.

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the
Otrada [13]

Answer:

Please check the explanation.

Step-by-step explanation:

a)  How much will you have at the middle of the first year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 0.5 years

Total amount = A = ?

Using the formula

A\:=\:P\left(1+\frac{r}{n}\right)^{nt}

substituting the values

A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}

A=300\cdot \frac{2.06}{2}

A=\frac{618}{2}

A=309 $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 0.5 years is $ 309.00.

Part b) How much at the end of one year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 1 years

Total amount = A = ?

Using the formula

A\:=\:P\left(1+\frac{r}{n}\right)^{nt}

so substituting the values

A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}

A=300\cdot \frac{2.06^2}{2^2}

A=318.27 $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 1 year is $ 318.27.
