Divide 20 chocolates between Adi and Suresh such that adi gets 60% while Suresh gets 40% of the chocolates

Eddi Din [679]

Hello!

To find how much chocolate Adi and Suresh receives, you need to convert the percentage to a decimal, then you multiply that decimal by the total number of chocolates, which is 20.

To convert percentages to decimals, divide the percentage by 100, and remove the percentage.

60% / 100 = 0.60

20% / 100 = 0.20

Then, we multiply 0.60 and 0.20 by 20.

0.60 x 20 = 12

0.40 x 20 = 8

Therefore, Adi gets 12 chocolates and Suresh gets 8 chocolates.

Stella [2.4K]

Apply distributive property
-9-9x+4=-5

Combine like terms
-5-9x=-5

Add 5 to both sides
-9x=0

Divide both sides by -9
x=0

Final answer: x=0

Find the percent of increase for 4 to 7. round to the nearest tenth if necessary. also someone please explain how to do this.

dem82 [27]

Answer:

75%

Step-by-step explanation:

The percent increase is calculated as

percent increase = $\frac{increase}{original number}$ × 100%

increase = 7 - 4 = 3, thus

% increase = $\frac{3}{4}$ × 100% = $\frac{3(100)}{4}$ = 75%

Which of the following recursive formulas represents the same arithmetic sequence as the explicit formula an = 5+ (n-1)2?

andrezito [222]

Answer:

$a_1 = 5$

$a_n = a_{n-1} + 2$

Step-by-step explanation:

Given

$a_n = 5 + (n - 1)2$

Required

The equivalent recursive function

The general explicit function is:

$a_n = a_1+ (n - 1)d$

So, by comparison

$a_1 = 5$

$d = 2$

The recursion of an arithmetic sequence is:

$a_n = a_{n-1} + d$

Substitute 2 for d

$a_n = a_{n-1} + 2$

Hence: (a) is correct
