Which of the following represents "Twice the abscissa increased by three times the ordinate is ten"?3x + 2y = 10
2y + 3x = 10
2x + 3y = 10

Answers

The abcissa is the name given to the x-coordinate while the ordinate is the other name for the y-coordinate. So, in mathematical terms, "twice the abcissa increased by three times the ordinate is ten" is then described by the third option which is 2x+3y=10. 

Answer:

Step-by-step explanation:

Given : Twice the abscissa increased by three times the ordinate is ten.

To find : which equation represent Twice the abscissa increased by three times the ordinate is ten.

Solution : We have  abscissa = x.

                                Ordinate = y.

According to given statement :

Twice the abscissa = 2 * x .

Three times the ordinate = 3 * y.

Twice the abscissa increased by three times the ordinate is ten :

    2 * x  +  3 * y = 10.

Therefore,  This  equation 2 * x  +  3 * y = 10 is correct.

PLEASE HELP!A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.

Which expression can be used to determine the greatest possible volume of the cardboard box?


A) (x−7)(x−11)x
B) (7−2x)(11−2x)x
C) (11−7x)(11x−7)
D) (7x−11)(7−11x)

Answers

Answer:

Option B

Step-by-step explanation:

Given is a rectangle with width 7 and length 11.

From each corner of the rectangle a square of length x is cut and foled to make a box

Now for the open box we made, height = x

width = rectangle width - 2 times d

= 11-2x

Length = rectangle length-2x

Hence volume of box

=lwh

= (7-2x)(11-2x)x

Answer: B) (7-2x)(11-2x)x

Step-by-step explanation:

Given: The length of the cardboard = 11 in.

The width of the cardboard =7 in.

If a box is created without a top from a piece of cardboard, but cutting out square corners with side length x, then the dimensions of box will be:-

Width (w)= 7-2x

length (l)= 11-2x

Height (h)=x

Now, volume of rectangular box is given by :-

V=lwh\n\n\Rightarrow\ V=x(7-2x)(11-2x)

Hence, the expression can be used to determine the greatest possible volume of the cardboard box is given by :-

(7-2x)(11-2x)x

What is the percent of change from 45 to 56 round to the nearest percent

Answers

Step-by-step explanation:

This problem is not about percent or relative change, but about absolute change. Its solution is very simple:

Absolute change, or

change = new value - old value
