SVEN [57.7K]

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Principal ( P ) = £ 1800
Rate ( R ) = 5%
Time ( T ) = 3 years

$\underline{ \underline{ \text{To \: find}}} :$

Total amount

$\underline{ \underline{ \text{Solution}}}:$

First , finding the amount of interest :

$\boxed{ \sf{Interest = \frac{PTR}{100}}}$

⇢ $\sf{Interest = \frac{1800 \times 5 \times 3}{100}}$

⇢ $\sf{Interest = \frac{27000}{100}}$

⇢ $\sf{Interest = £ 270}$

Now , Finding the total amount :

$\boxed {\sf{Total \: amount = Principal + Interest}}$

⇢ $\sf{Total \: amount = 1800 + 270}$

⇢ $\sf{Total \: amount = \: £ 2070}$

$\red{\boxed{ \boxed{ \tt{Our \: final \: answer : brian \: will \: have £ 2070 \: after \: 3 \: year.}}}}$

Find the first four terms of the sequence<br> An=2a n-1,where a1=3

yKpoI14uk [10]

The first four terms of the sequence are 3 , 6 , 12 , 24

Step-by-step explanation:

We need to find the first four terms of the sequence $a_{n}=2a_{n-1}$

where $a_{1}=3$ to find them do that

Substitute n by 2 in the rule to find $a_{2}$
Substitute n by 3 in the rule to find $a_{3}$
Substitute n by 4 in the rule to find $a_{4}$

∵ $a_{n}=2a_{n-1}$

- Substitute n by 2 to find the 2nd term

∴ $a_{2}=2a_{2-1}$

∴ $a_{2}=2a_{1}$

∵ $a_{1}=3$

∴ $a_{2}=2(3)$

∴ $a_{2}=6$

- Substitute n by 3 to find the 3rd term

∴ $a_{3}=2a_{3-1}$

∴ $a_{3}=2a_{2}$

∵ $a_{2}=6$

∴ $a_{3}=2(6)$

∴ $a_{3}=12$

- Substitute n by 4 to find the 4th term

∴ $a_{4}=2a_{4-1}$

∴ $a_{4}=2a_{3}$

∵ $a_{3}=12$

∴ $a_{4}=2(12)$

∴ $a_{4}=24$

The first four terms of the sequence are 3 , 6 , 12 , 24

You have been hired as a marketing consultant to Johannesburg Burger Supply, Inc., and you wish to come up with a unit price for

BartSMP [9]

Answer:

The demabd function is:

$q(p)= -4500p+18000$

Step-by-step explanation:

The demand follow the linear equation $q(p)=mp+b$

1. When p=$2.00 and q=9000, the equation is:

$9000=m(2.00)+b (1)$

2. Whe p=$4.00 and q=0, the equation is:

$0=m(4.00)+b (2)$

3. Solve equation (1) for b:

$9000=2m+b\\9000-2m=2m+2m+b\\9000-2m=b$

4. Replace the value of b in equation (2)

$0=4m+b\\0=4m+9000-2m\\0=2m+9000\\0-9000=2m+9000-9000\\-9000=2m\\\frac{-9000}{2m}=\frac{2m}{2m}\\ -4500=m$

The value of m is 4500

5. Calculate b, replacing m:

$0=4m+b\\\\0=4(-4500)+b\\0=-18000+b\\18000=b$

The value of b is 18000

What is the solution of 3x=67 ?

natta225 [31]

Answer:

22.3 repeating

Step-by-step explanation:

3x divided by 3x equals 1x or just x but to divide this you also have to divide the other side of the equals sign by 3 as well therefore the answer is 22.3 repeating

You might find it easy by putting it in fractions such as 3x/3x = 67/3 so x =22.3 repeating
