length =88cm

breadth=21cm

when it is rolled it becomes cylinder

having circumference 88cm

2πr=88cm

r=88×7/44

r=14

h=21

total surface area of the cylinder =2πr(r+h).

=2×22/7×14(14+21)

=3080cm²

Michael has a substantial student debt, but he recently got a new job, which came with a signing bonus. He calculates that with
kykrilka [37]

Answer:

5000

Step-by-step explanation:

Given the question :

The size of debt after m months is respresented by the expression :

36,700 - (5000 + 500m)

Since Michael has decided to dedicate the entirety of his signing bonus towards paying his debt, then that is a constant and one-off payment.

Also, a fixed portion of his salary each month has also been assigned towards paying off his debt,

Then the amount paid from his salary after a certain number of months will be:

Fixed amount × number of months = 500 × m

Amount paid using signing bonus will be a constant = 5000

Total debt amount = 36,700

Size of debt left after m months :

Total debt - ( signing bonus - fixed amount × m)

Hence signing bonus = 5000

baherus [9]

Answer:

Step-by-step explanation:

1) The given inequality is

|\sqrt{n} \frac{(\bar R_n-p)}{\sqrt{p(1-p)} } |

\to n( \bar R _n - p)^2

\to n\bar R +np^2-2nR_np

Arranging the terms  with p² and p, we get

p^2(n+q^2_{\alpha /2)-p(2n \bar R _n+q^2_{\alpha / 2})+n \bar R ^2 _n

Hence, the inequality is of the form

Ap² + Bp + c < 0

2. A quadratic equation of the form

Ap² + Bp + c < 0 with A > 0 looks like

James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be
Deffense [45]

Answer:

8.0%

Step-by-step explanation:

We have been given that James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be $76.57.

First of all, we will find the amount paid for the year using the monthly rate by multiplying $76.57 by 12 (1 year = 12 months).

\text{Amount paid for the year using the monthly rate}=\$76.57\times 12

\text{Amount paid for the year using the monthly rate}=\$918.84

Now, we will use percent change formula.

\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100

\text{Percent change}=\frac{\$918.84-\$850.80}{\$850.80}\times 100

\text{Percent change}=\frac{\$68.04}{\$850.80}\times 100

\text{Percent change}=0.0799717912552891\times 100

\text{Percent change}=7.99717912552891\%

\text{Percent change}\approx 8.0\%

Therefore, Mr. Harmon is paying 8.0% more for the year using the monthly rate.
