if y=60 when x=80, find x when y=-20.

Last year the chess club had 30 members. This year the club has 24 members.

Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.

To find the percent decrease, you have to use the following formula.

[tex]\frac{Difference}{Original} \times 100[/tex]

Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.

Substitute the numbers into the formula.

[tex]\frac{Difference}{Original} =\frac{6}{30} =0.2[/tex]

To convert the decimal to a fraction, multiply the decimal by 100.

[tex]0.2 \times 100 = 20 \%[/tex]

The answer is the number of chess members decreased by 20%.

____

Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.

Answer:

Decreasing

Step-by-step explanation:

The percentages are decreasing because one year the club had 30 members and the present year has 24 members that decreased by 6!

Step-by-step explanation:

We use the property that  (all numbers being positive)

0 < a < b < c  -->  0< a^2 < b^2 < c^2

so:

1 <  2 <   sq(7)   < 3 < 4 <  5            

1 <  4 <  7   < 9 < 16 < 25      

Answer:

x = 7

Step-by-step explanation:

Given s(x) = - 3(x - [tex]\frac{2}{3}[/tex]) + 19 and s(x) = 0, then equate the right sides, that is

- 3(x - [tex]\frac{2}{3}[/tex] ) + 19 = 0 ( add 19 to both sides )

- 3(x - [tex]\frac{2}{3}[/tex] ) = - 19 ← distribute the parenthesis

- 3x + 2 = - 19 ( subtract 2 from both sides )

- 3x = - 21 ( divide both sides by - 3 )

x = 7

Answer:

The relationship is not proportion because the value of [tex]\frac{y}{x}[/tex] is not equivalent for each point in the relationship ⇒ C

Step-by-step explanation:

Let us use the information, above to solve the question

→ From the given graph

∵ The coordinates of the points are (1, 10), (2, 20), (4, 25), (6, 40)

∵ The equation of proportion is [tex]\frac{y}{x}[/tex] = k

→ Let us check if all the points satisfy the equation or not

∵ x = 1 and y = 10

∴ [tex]\frac{10}{1}[/tex] = k

∴ 10 = k

→ Check the other points if they give the same value of k or not

∵ x = 2 and y = 20

∴ [tex]\frac{20}{2}[/tex] = k

∴ 10 = k

∵ x = 4 and y = 25

∴ [tex]\frac{25}{4}[/tex] = k

∴ [tex]\frac{25}{4}[/tex] = k

∵ x = 6 and y = 40

∴ [tex]\frac{40}{6}[/tex] = k

∴ [tex]\frac{20}{3}[/tex] = k

∵ Not all points satisfy the same value of k

∴ The relation does not represent a proportional relation

The relationship is not proportion because the value of [tex]\frac{y}{x}[/tex] is not equivalent for each point in the relationship.

Answer:

2 13/20

Step-by-step explanation:

Answer:

2 13/20

Step-by-step explanation:

we can split up 2.65 into a whole number and a decimal

2.65

= 2 + 0.65      (note that 0.65 = 65/100)

= 2 + 65/100

= 2 65/100   (we can see that both numerator and denominator are multiples of 5, hence we can try to simply by dividing both numerator and denominator by 5)

= 2 (65÷5) / (100÷5)

= 2 13/20   (answer)

The expression is already in decimal form.

Answer:

D: 3

Step-by-step explanation:

2 is not a factor of three

The number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. The number of components of a specific size is expressed as a fraction.

The fractions will have all the numbers 18, 12, and 6 as the common denominator but can not have 3 as a common denominator.

Therefore, the number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.

Step-by-step explanation:

They do not create a triangle because if you follow the expression: a^2+b^2=c^2 it does not equal. Hope I helped :)

Answer:

a^2 + b^2 = c^2  - Pythagorean Theorem

6^2 + 10^2 = 15^2

36 + 100 = 225

136 doesn't equal 225

So, no, the sides lengths don't make a triangle.

Answer: 21

Step-by-step explanation:

Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.

Since, 108 = 2 x 2 x 3 x 3 x 3

84 =  2 x 2 x 3 x 7

60 = 2 x 2 x 3 x 5

HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]

= 12

Greatest number of plants in each row = 12

Number of rows for mango = [tex]\dfrac{108}{12}=9[/tex]

Number of rows for guava = [tex]\dfrac{84}{12}=7[/tex]

Number of rows for sapota = [tex]\dfrac{60}{12}=5[/tex]

Total rows = 9+7+5= 21

Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted​ = 21

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Given

5x + y = - 9 ( subtract 5x from both sides )

y = - 5x - 9 ← in slope- intercept form

with slope m = - 5

Parallel lines have equal slopes, thus

The slope of a parallel line to the given equation is m = - 5
