the local chess club has 60 member. 24 of them are younger than twenty. what percent of members of the chess club are younger than 20

Answers

You can first write it as a fraction. 24 out of the 60 members are younger than twenty.

24/60

Simplify by dividing the numerator and denominator by the GCF, 12:

2/5

Percentages are parts of 100, so we want to get 100 in the denominator to find the percentage. 100 / 5 = 20, multiply numerator and denominator by 20:

40/100

This is 40 parts of 100 or 40%.

So 40% of the members of the chess club are younger than 20.

The local chess club has 60 members and 24 of the members are younger than 20. What percent of members are younger than 20?

The fraction [tex]\frac{24}{60}[/tex] represents the 24 members that are younger than 20 out of all the members in the club.

To find out what percent of members are younger than 20, we can turn [tex]\frac{24}{60}[/tex] into a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 60 using 12.

24 ÷ 12 = 2

60 ÷ 12 = 5

Now, we have our reduced fraction which is [tex]\frac{2}{5}[/tex].

2 ÷ 5 = 0.4

0.4 × 100 = 40%

Therefore, 40% of the chess club members were under 20.

Sonia makes a wooden frame around a square picture. The frame is made of 4 congruent trapezoids. The shorter base is 9 in., the longer base is 12 in., and the height is 1.5 in. What is the area of the picture frame? PLEASE tell me why the answer is that answer.

Answers

To find the answer you will find the area of one trapezoid, and then multiply it by four because all 4 trapezoids are congruent. To find the area of one trapezoid you will use the formula A=(b1 + b2)h/2. The b's stand for the bases and h is the height. So, (12+9) x 1.5 first. This equals 31.5. Then take 31.5 and divide by 2 to get 15.75 square inches for one. 15.75x4=63 square inches. I have included A picture to show you why a trapezoid uses the formula it does.

Final answer:

The area of Sonia's picture frame is determined by calculating the area of one trapezoid with given dimensions and multiplying by four. The area of each trapezoid is 15.75 square inches, resulting in a total frame area of 63 square inches.

Explanation:

The area of Sonia's picture frame can be calculated by finding the area of one of the congruent trapezoids and then multiplying it by four, since there are four trapezoids making up the entire frame. The formula to calculate the area of a trapezoid is: Area = (1/2) × (base1 + base2) × height. In this case, the shorter base (base1) is 9 inches, the longer base (base2) is 12 inches, and the height is 1.5 inches. Substituting these values into the formula gives us: Area of one trapezoid = (1/2) × (9 in + 12 in) × 1.5 in = (1/2) × 21 in × 1.5 in = 15.75 in2. The total area of the frame is then four times this amount, which equals 63 in2. This answer explains how to calculate the area of a trapezoid and then applies the concept to find the total frame area.

Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value?

f(x) = 20,000(0.85)x
f(x) = 20,000(0.15)x
f(x) = 20,000(1.15)x
f(x) = 20,000(1.85)x

Answers

The first one: f(x) = 20,000(0.85)^x (make sure you use the carrot thingy when you type these, otherwise you get a linear equation).

If the car is depreciating in value, that means you only have a certain percentage of its value left after a certain amount of time. If you lose 15% of the car's value each time, you're left with 85% of the car's value each time since 15 subtracted from 100 is 85. In order to start this equation, the first time the car depreciates in value, you will be multiplying 20,000 by 0.85 (percentage in decimal form) to determine what the value of the car is after one depreciation. Since this equation is the only one in which 20,000 is multiplied by 0.85, the first equation is correct.

The value of Terrence's car after x years is

A = 20,000 ( [tex]1-0.15)^x[/tex]

What is depreciation?

Subtract the asset's salvage value (what you expect it to be worth at the end of its useful life) from its cost to calculate depreciation using the straight-line technique. The depreciable basis, or the amount that can be depreciated, is the result. Divide this figure by the number of years the asset will be useful.

Depreciation is the rate at which an object's value declines over time.

it is given by the formula,

A = P [tex](1-r)^t[/tex]

where A is the value of object after x period of time, P is the principal amount, r is the rate of depreciation, and t is the for the time period.

Given:

Terrence buys a new car for $20,000,

rate of depreciation = 15%,

We know the formula of the rate of depreciation,

A = P [tex](1-r)^t[/tex]

Here A= $20, 000

r = 15% = 0.15

So, the value of Terrence's car is A = 20,000 ( [tex]1-0.15)^x[/tex].

The graph of the function f is shown. f(4) =
A) 0
B) 1
C) 4
D) 5

Answers

Let me first give you an overview of the coordinate plane. The coordinate plane has an x-axis that runs horizontally left to right and a y-axis that runs vertically up and down. The axes intersect at a right angle at the origin, which is (0, 0). If you have a point, say (2, 5), then the point is located two steps to the right of the origin and five steps up. Remember to always go left and right first before going up and down. This is because the y-coordinate depends on the x-coordinate.

Sometimes the y-coordinate is called f(x), which is the function value at a given x-value. Again, this is because f(x) depends on the x-value.

The numerical value of f(4) is how ever many steps up or down the graph is (the graph is a visual representation of f(x) points). At x = 4, the graph is at 1, so f(4) = 1.

What you must do for this case is a division to find the number of times that Bertha submerges with respect to Vernon.
We have then:
Bertha's dive ended = -32 m
Vernon's dive ended -4 m
N = (Bertha's dive ended) / (Vernon's dive ended)
N = (- 32) / (- 4)
N = 8

Given plans:
Plane 1: 12 game plan cost=$192
Cost of single game= 192/12 =$16

Plane 2: 28 game plan cost=$420
Cost of single game= 420/28 = $15

So plan 2 ( 28 games for $420) is the better plan .

Answer: 28 games for $420 is the better plan.

You have to divide the game plan cost by the number of games it provides to get the cost per game:

$192 / 12 = $16 a game

$420 / 28 = $15 a game

The 28-game plan is better value per game.

In m + 8, the variable m can have any value. Tell whether each statement is true or false. Then explsin your reasoning.

Answers

M can have any value because M can represent any number because it is the unknown.

Final answer:

In algebra, the variable 'm' in the expression 'm + 8' can indeed take on any value; therefore, the statement is true because variables are meant to be placeholders for a wide range of numbers.

Explanation:

In the expression m + 8, it is true that the variable m can have any value, which means that this expression does not impose any restrictions on the possible values of m. This type of statement involving a variable is common in mathematics, particularly in algebra where variables represent unknown quantities that can take on various values.

When evaluating statements for truth or false, the statement 'in m + 8, the variable m can have any value' is true. Variables, by their nature, are symbols that can represent any number, so unless specific limitations are given, we assume variables to have the full set of numbers (real numbers, integers, etc.) as potential values.

An artists builds a sculpture out of metal and wood that weighs 14.9 kilograms.3/4 of this weight is metal,and the rest is wood.How much does the wood part of the sculpture weigh?PLZZZ HELP!!!!!!!

Answers

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight = [tex] \frac{3}{4} *14.9=\frac{44.7}{4} =11.175 \;kilograms [/tex]

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

3.725 kilograms or ¹/₄ part

Further explanation

Given:

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.

³/₄ of this weight is metal, and the rest is wood.

Question:

How much does the wood part of the sculpture weighs?

The Process:

From the information above, we make a diagram that matches the composition of the sculpture material.

[tex]\boxed{metal}\boxed{metal}\boxed{metal}\boxed{wood} = 14.9 \ kilograms[/tex]

³/₄ of this weight is metal, and the rest is wood, which is [tex]\boxed{ \ 1 - \frac{3}{4} = \frac{1}{4} \ }[/tex].

And now, let us calculate the wood part of the sculpture weighs.

[tex]\boxed{ \ = \frac{1}{4} \times 14.9 \ kilograms \ }[/tex]

Both 4 and 14.9 are multiplied by 10.

[tex]\boxed{ \ = \frac{1}{40} \times 149 \ kilograms \ }[/tex]

[tex]\boxed{ \ = \frac{149}{40} \ kilograms \ }[/tex]

Both the numerator and denominator are divided by 4.

[tex]\boxed{ \ = \frac{37.25}{10} \ kilograms \ }[/tex]

[tex]\boxed{ \ = \frac{3,725}{1,000} \ kilograms \ }[/tex]

[tex]\boxed{\boxed{ \ 3.725 \ kilograms \ }}[/tex]

Thus, the wood part of the sculpture weighs is 3.725 kilograms or ¹/₄ part.
