What is 480 increased by 25%.
what is the new number?

Answers

Answer 1
Answer: The new number is 600.How do we get 600? Here’s how:
 1. First, we have to get the 25% of 480.
      Multiply 480to 25%.
                   480x 25%= n
Change 25% to decimal form.
                   25/100(as per value of % symbol)
                   25% is 0.25So, 480 x 25% = n is:
                 480x 0.25 = 120
  2.  Add 25% of 480 (120)and 480.
                480 + 120 =600
 Therefore, when 480 is increased by 25%, it is 600.  


Answer 2
Answer: 480 * 25%480 * 0.25480 * 0.25 = 120480 + 120 = 600.480 increased by 25% is 600

Answer:

  B.  $2862

Step-by-step explanation:

Using n=5 in the given equation, we get ...

  A(5) = 2700 + (5-1)(.015·2700) = 2700 +4(40.50)

  A(5) = 2862.00

In year 5, you will have $2862 in the account.

Comment on the given equation

The given equation tells you the amount in the account at the beginning of the year, before it earns any interest. Since that is the equation given, we presume that is the answer desired. In most "account balance" problems, you are interested in the amount at the end of the interest-earning period.

beth needs 5 1/4 quarts of paint to paint some walls .if paint cost $13.99 for one quart how much will it cost her

Answers

In this question all the details required to solve the problem is already provided. Firstly the fraction given for the amount of paint required needs to be simplified for future use. then we have to get to the problem.
Beth requires 5 1/4 quarts of paint to paint some wall
Cost of 1 quarts of paint = $13.99
Amount of paint required by Beth = 5 1/4
                                                     = 21/4
Cost of 21/4 quart of paint = (13.99 * 21/4)
                                           = 293.79/4
                                           = 73.45
So Beth requires $73.45 worth of paint to paint the amount of wall she desired.
It will cost Beth $73.45.You can multiply 5 by 13.99 to get how much 5 quarts costs.5 x 13.99=$69.95Now, how do we find how much 1/4 of a quart costs? You just divide 13.99 by 4.13.99 / 4=$3.4795All you have to do now is just add the cost of 5 quarts to the cost of 1/4 of a quart.69.95 + 3.4795=$73.4475Now you just round to get your final answer.$73.4475 >> $73.45

Doug purchased land for $8,000 in 1995. The year value of the land depreciated by 4% each year thereafter. Use an exponential function to find the approximate value of the land in 2002.

Answers

Answer:

Option C. $6,012

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to

V=P(1-r)^(t)

where  

V is the the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal

t is Number of Time Periods  

in this problem we have  

t = 7 years

P = $8,000

r = 0.04

substitute in the formula above

V = 8,000(1-0.04)^(7) = 6,012

Hope this helps :)

Answer:

6. 5x+15

Step-by-step explanation:

Distributive property would be the first thing to do, so

-3(2x-5+x)

-6x + 15 -3 x

12x-6x-5-3x+2x

Combine all like terms which are, 12x-6x=6x-3x=3x+2x=5x, and the positive fifteen doesn't have any like terms so we leave that just as it is

5x+15 should be the answer

Three less than one-fourth of the product of eight thirds and nine. Please write equation, then solve.

Answers

Put simply, you have to work backwards in making the equations. Start with the product of 8/3 and 9.
(8)/(3)*9

 Next take 1/4 of that. This can be done in two ways, either multiplying by 1/4:
((8)/(3)*9)*(1)/(4)

, or dividing everything by 4.
((8)/(3)*9)/4

Finally, subtract three.

The final equation would read:
(((8)/(3)*9)*(1)/(4))-3



Using PE(M/D)(A/S), we'd start with (8)/(3)*9

3 and 9 cancel out to be 1 and 3, leaving us with (8)/(1), or 8, and 3 and this part of the equation reading 8*3, which is 24.

The next step is (24)/(4), which is 6.

Lastly we subtract 3 from six, leaving us 3.

¹/₄ × ( ⁸/₃ × 9 ) - 3 = 3

Further explanation

Order of Operations in Mathematics follow this following rule :

  • Parentheses
  • Exponents
  • Multiplication and Division
  • Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

Product of eight thirds and nine

(8)/(3) * 9

One-fourth of the product of eight thirds and nine

(1)/(4) * ( (8)/(3) * 9 )

Three less than one-fourth of the product of eight thirds and nine

(1)/(4) * ( (8)/(3) * 9 ) - 3

= (1)/(4) * ( (8 * 9)/(3) ) - 3

= (1)/(4) * ( (72)/(3) ) - 3

= (1)/(4) * 24 - 3

= (1 * 24)/(4) - 3

= (24)/(4) - 3

= 6 - 3

= \boxed {3}
