45% of the population of a city are men

leonid [27]

Answer:

$\boxed{\textsf{ The number of children is \textbf{24150}.}}$

Step-by-step explanation:

Given that the 45% of the population of a city are men and 15% are children . The number of women is 64,400 . And we need to find the number of children . Here ,

$\sf\implies Percentage_{(men)}= 45/% .\\\\\sf\implies Percentage_{(children)}= 15\% .$

So the percentage of women will be equal to [ 100 - ( 45 -15) ]% = [ 100 - 60 ]% = 40% .

So let us take the total number of people be x . So ,

$\purple{\bigstar}\underline{\underline{\boldsymbol{ According\ to \ Question :- }}}$

$\sf\implies 40\% \ of \ x \ = \ 64,400 \\\\\sf\implies \dfrac{40x}{100}= 64,400 \\\\\sf\implies x =\dfrac{64,400\times 100}{40}\\\\\sf\implies \boxed{\pink{\sf x = 161,000 }}$

$\rule{200}2$

The percentage of children = 15% :-

$\sf\implies Number_{(children)}= 15\% \ of 161,000\\\\\sf\implies Number_{(children)}= \dfrac{15}{100}\times 161,000 \\\\\sf\implies \boxed{\pink{\frak {Number_{(children)}= 24150 }}}$

Ms. Allen asked each of her 30 students to select their favorite type of music. How many students chose Rock 1/3 chose hip hop 1

dalvyx [7]

Answer: 14

Step-by-step explanation:

Fraction that choose hip hop= 1/3

Fraction that choose rap = 1/5

Fraction that choose rock will be:

= 1 - (1/3 + 1/5)

= 1 - (5/15 + 3/15)

= 1 - 8/15

= 7/15

Number of students that choose rock will be:

= 7/15 × 30

= 7 × 2

= 14 students

We then multi

The ratio of students who play musical instruments to students who play sports is 3:20. if there are 40 students who play sports

melomori [17]

Based on the ratio, 6 students play musical instruments.

The mentioned problem can be solved using the concept of ratio and proportion. We will equate the two ratio. Let us assume the number of students who play musical instruments be x.

Forming the equation -

3 : 20 = x : 40

Rewriting the equation with respect to x

x = (40 × 3) ÷ 20

Performing multiplication and division on Right Hand Side of the equation

x = 120 ÷ 20

Performing division on Right Hand Side of the equation

x = 6

Therefore, 6 students play musical instruments.

prealgebra.. please help... examples for each one are commutative property, associative property, additive identity property and

Vadim26 [7]

Step-by-step explanation:

Lets first understand what each of these properties are.

Commutative property - an operation is commutative if changing the order of the operands does not change the result
Associative property - an operation is associative if grouping the operands with parenthesis does not change the result
Additive identity property - this property says that when you add 0 to a real number, or add a real number to 0, the result is the same real number
Additive inverse property - the additive inverse of a number is the number required to add to make the result 0

Problem 1

This is an example of the additive inverse property because -2 + 2 = 0.

Problem 2

This is an example of the associative property because the numbers are grouped differently, but still equal each other.

Problem 3

This is an example of the commutative property because the numbers are arranged differently but still equal each other.
