The ratio of the number of men to women to adults is 5 : 3 : 4 and the number of women is 360

From the question, we have the following ratios that can be used in our computation:

Men : Women = 5 : 3

Children : Adults = 1 : 2

This means that

Children : Men : Women  = 1 : 2(Men : Women)

So, we have the following representation

Children : Men : Women  = 1 : 2(5/8 : 3/8)

Open the brackets

Children : Men : Women  = 1 : 5/4 : 3/4

Multiply through by 4

Children : Men : Women  = 4 : 5 : 3

Rewrite the ratio as

Men : Women : Children 5 : 3 : 4

Here, we have

People = 1440

Recall that

Men : Women : Children 5 : 3 : 4

So, we have

Women = 3/(5 +3 + 4) * 1440

Evaluate the sum

Women = 3/12 * 1440

Evaluate the products

Women = 360

Hence, the number of women is 360

The value of x is 18 if ∠C and ​ ∠D ​ are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

∠C and ​ ∠D ​ are vertical angles.

5x-7 = 8x-55

Subtract 5x from both sides:

-7 = 3x -55

Add 55 to both sides:

3x = 48

x = 48 /3

x = 16

Thus, the value of x is 18 if ∠C and ​ ∠D ​ are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.

To solve this expression, we need to use the rules of order of operations, which dictate the order in which mathematical operations should be performed. The order of operations is typically abbreviated using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Using the order of operations, we can solve the expression as follows:

64 - (-2)⁵ ÷ 2³ + (-1)³ · (0.5)²

= 64 - (-2)⁵ ÷ 8 + (-1)³ · 0.25

= 64 - (-32) ÷ 8 + (-1)³ · 0.25

= 64 + 32 + (-1)³ · 0.25

= 96 + (-1)³ · 0.25

= 96 + (-1) · 0.25

= 96 - 0.25

= 95.75

Therefore, the final result of the expression is 95.75

A is the CD's total value after t years.

The interest rate is represented by r.

The periodic interval at which it was compounded is represented by n.

P stands for the principal, or the amount of the CD purchase.

Considering the data provided,

P = 1500

r = 6% = 6/100 = 0.06

Since it was compounded 12 times in a year, n = 12.

a) The monthly repayment amount is $466.67.

b) The total interest paid on loan is $21,000.

Interests on student loans are computed using the simple interest system, instead of compound interest.

The total interest payable is a function of the outstanding balance (principal amount plus accumulated interest) during the non-payment period, the interest rate, and the number of years of payment.

Unsubsidized Loans plus Accumulated Interest = $35,000

Interest rate (APR) = 6%

Repayment period = 120 months (10 years x 12)

Interest on the student loan = $21,000 ($35,000 x 6% x 10)

Total amount to repay for 10 years = $56,000

Monthly repayment = $466.67 ($56,000 ÷ 120)

Thus, the monthly repayment will be $466.67, which is determined by adding the total interest for 10 years to the outstanding balance and dividing the result by 120 months.

[tex]n=45 \implies \frac{180(n-2)}{n}=\boxed{172^{\circ}}[/tex]

The degree measure of one angle of a 45-sided regular polygon is 172°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, the polygon has 45 sides.

To find the measure of an interior angle of a regular polygon,

we make use of the formula for each angle = (n - 2) × 180 / n.

The formula calculated is only valid in cases of regular-sided polygons.

n =  45 substituting the value of n to the formula.

(n - 2) × 180 / n

= 180 ( 45-2) / 45

= 180 x 43 / 45

= 7740 / 45
