Answer:

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

QUES
snow_tiger [21]

Answer:

Now, derive it from the calculations

Step-by-step explanation:

Net income = 100% = N120,000

therefore

1. Food

40%/100% = 2/5 of N120,000

= N48,000

2.Housing

30%/100% = 3/10 of N120,000

= N36,000

3. Savings

20%/100% = 2/10 (or 1/5) of N120,000

= N24,000

4. Miscellaneous

10%/100% = 1/10 of N120,000

= N 12,000

Solvethe equation 3(x-5)/2=2(x+5)/3
Nataliya [291]
3(x−5)/2=2(x+5)/3

Cross-multiply.

(3(x−5))/2=(2(x+5))/3

3(x−5)*(3)=2(x+5)*(2)

9x−45=4x+20

Subtract 4x from both sides.

9x−45−4x=4x+20−4x


5x−45=20

Add 45 to both sides.

5x−45+45=20+45

5x=65

Divide both sides by 5.

5x/5=65/5

x=13

Lian has $1.00. She has only nickels and dimes. Lian has twice as many dimes as nickels. How many dimes does she have?
Anna11 [10]

Answer: 8

Step-by-step explanation:

Given

Lian has \$1.00 and she has twice as many dimes as nickels

Suppose she has x nickels

So, the number of dimes is 2x

Nickel is equivalent to 5 cents and dime is equivalent to 10 cent

\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4

Therefore she has 8 dimes with her.
