s(x)= -3(x-2/3) + 19; s(x) = 0

Answers

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

express 2.65 as a mixed number in the lowest terms

Answers

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 graph represents the relationship between the cost of renting a trailer y for x hours,, please help

Answers

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:

The relationship between x and y are proportional if [tex]\frac{y}{x}[/tex] = k, where k is a constantThe proportional relation represented graphically by a line passes through the origin point

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.

Solve for the indicated variable.

for a small party of 12 people, the caterer offered a choice of a steak dinner for $12:00 per or a chicken dinner for $10.50 the final cost for the meals was 138:00. how many of each was ordered?​

Answers

Answer:

let the $12 dish be x and the other y

x + y = 12 <--- 1

12x + 10.50y= 138 <--- 2

multiply equation 1 by 12

so now we have

12x + 12y = 144

12x + 10.50y = 138

now subtract each one and that cancels out x

1.5y = 6

y = 4

now subsitute that into any equation

x + 4 = 12

x = 12 - 4

x = 8

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


Please help asap

Answers

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!

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:

Which angle has a measure equal to the sum
of m_SQR and mzQRS?
O ZRSC
O LSRE
O ZDQS
O ZQSR

Answers

Answer:< RSC

Step-by-step explanation:

The angle has a measure equal to the sum of m <SQR and m <QRS is

m <RSC.

The correct option is A.

We have the information from which we can write

<SQR and < QRS are two interior angles of triangle QRS

Then, m<QSR = 180 - (sum of other 2 angles)

m<QSR = 180 - (m<SQR + m<QRS) (Angle sum property)

Also, m<RSC = 180 - m<QSR

Then <RSC = (m<SQR + m<QRS)

Thus, the ideal solution is A.
