Interest due on 1200 at 8% for 240 days

kompoz [17]

Let us use 360 days for the 1-year term.

principal = 1,200

interest rate = 8% unless otherwise stated, this rate is per annum or annual rate.

term = 240 days

Simple Interest = Principal * interest rate * term

S.I = 1,200 * 8% * 240/360

S.I = 1,200 * 0.08 * 0.667

S.I = 64.032 rounded off to 64

The interest due 1200 at 8% rate is 64 in 240 days.

Hope that helps and feel free to ask me more questions :)

Answer:

$\huge \boxed{K=20}\checkmark$

B. 20

Step-by-step explanation:

First, you divide by 5 from both sides of equation.

$\displaystyle \frac{5k}{5}=\frac{100}{5}$

Simplify, to find the answer.

$\displaystyle 100\div5=20$

$\huge \boxed{K=20}$ , which is our answer.

Two friends are collecting cards. Frank has 7 more than half the number of cards as his friend. Together they have 42 cards. How

Naddika [18.5K]

Answer:

The number of cards Frank has is 18 and the number of cards his friend has is 24.

Step-by-step explanation:

The correct question is

Two friends are collecting cards. Frank has 6 more than half the number of cards as his friend. Together they have 42 cards. How many cards does each friend have?

Let

x ----> the number of cards that Frank has

y ----> the number of cards that his friend has

we know that

Together they have 42 cards

$x+y=42$ ----> equation A

Frank has 6 more than half the number of cards as his friend

$x=\frac{y}{2} +6$ ---> equation B

Solve the system by substitution

Substitute equation B in equation A

$\frac{y}{2} +6+y=42$

solve for y

$\frac{3}{2}y=42-6\\\\\frac{3}{2}y=36\\\\y=36(2)/3=24$

Find the value of x

$x=\frac{24}{2} +6=18$

therefore

The number of cards Frank has is 18 and the number of cards his friend has is 24.

What is the factored form of 6n4 – 24n3 + 18n?

seropon [69]

Answer: Its factored form will be

$6n(n-1)(n^2-3n-3)$

Step-by-step explanation:

Since we have given that

$6n^4-24n^3+18n$

So, we need to factor ,

$6n(n^3-4n^2+3)$

Now,

$\text{Let }p(n)=n^3-4n^2+3$

Now, by hit and trial method, we put n=1,

$p(1)=1^3-4\times1^2+3=1-4+3=1-1=0$

$n=1\\n-1=0$

So, n-1 is also factor of p(n).

Now,

$\frac{n^3-4n^2+3}{n-1}=n^2-3n-3$

So, its factored form will be

$6n(n-1)(n^2-3n-3)$
