Step-by-step explanation:
Guiana and jimmy are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Hi oh sold 10 rolls of plain wrapping paper and 7 rolls of holiday wrapping paper for a total of $330. Jimmy sold 4 rolls of plain wrapping paper and 14 rolls of holiday paper for a total of $356. What is the cost of each one roll of plain wrapping paper and one roll of holiday wrapping paper?
Answer:
The answer is "p=25.63 and h= 6.24".
Step-by-step explanation:
p = cost of the plain
h = cost of the holiday
[tex]\to 10p + 7h = 330.........(i)\\\\\to 4p + 14h = 356........(ii)[/tex]
multiply by 2 in equation (i) and subtract from the equation (ii):
[tex]\to 20p + 14h = 660\\\\\to 9p + 14h = 378\\\\subtract\\\to 11 \ p =\ 282 \\\\\to p = \frac{282}{11}\\\\\to p = \$ \ 25.63[/tex]
put the value of p in equation (i):
[tex]\to 10(25.63)+7h=330\\\\\to 256.3+7h=330\\\\\to 7h=330 - 256.3\\\\\to 7h=330 - 256.3\\\\\to 7h= 43.7\\\\\to h= \frac{43.7}{7}\\\\\to h=6.24[/tex]

what is the x-coordinate of (-2,5)?
Answer: -2
Explanation: The -2 is called the x-coordinate
or horizontal move from the origin.
All points are written in the form (x, y).
perimeter of rectangular plot is 36 meters the length is increased by 6meters and breadth is decreased by 3 meters the area of the plot remains the same what is the length of the plot
Perimeter of a rectangular plot = 36 m.
Find:length of the plot
Solution:Let the length of the plot be x and it's breadth be y.
We know that,
Perimeter of a rectangle = 2(length + breadth)
⟹ 2(x + y) = 36
⟹ x + y = 36/2
⟹ x = 18 - y -- equation (1)
Also,
If length is increased by 6 m & breadth is decreased by 3 m , the area remains same.
Area of a rectangle = length * breadth
So,
(x + 6) * (y - 3) = xy
⟹ x(y - 3) + 6(y - 3) = xy
⟹ xy - 3x + 6y - 18 = xy
Substitute the value of x from equation (1).
⟹ - 3(18 - y) + 6y = 18
⟹ - 54 + 3y + 6y = 18
⟹ 9y = 18 + 54
⟹ y = 72/9
⟹ y = 8 m
Substitute the value of y in equation (1).
⟹ x = 18 - 8
⟹ x = 10 m
Hence,
Length (x) = 10 m
Breadth (y) = 8 m.
∴ The length of the plot is 10 m.
I hope it will help you.
Regards.

452 divided 15 what would be the answer of this? If anyone knows please answer
Answer:
The answer to this question is given below in the explanation section
Step-by-step explanation:
This is a simple division question.
In division there are some terms used that are:
Dividend: The number which we divide is called a dividend. In this case, 425 is a dividend
Divisor: The number by which we divide is called the divisor. In our question, it is 15.
Quotient: The result obtained is called the quotient.
Remainder: The number left over is called the remainder.
So the answer to this question is:
452/15= 30.133
so the answer is 30.1333

Which of the following possible rational roots is a root of the function f(x)=x^3-3x^2+5x-15? *
5 points
-3
-1
1
3
Given:
The function is
[tex]f(x)=x^3-3x^2+5x-15[/tex]
To find:
The root of the function from the given possible roots.
Solution:
We have,
[tex]f(x)=x^3-3x^2+5x-15[/tex]
At x=-3,
[tex]f(-3)=(-3)^3-3(-3)^2+5(-3)-15[/tex]
[tex]f(-3)=-27-27-15-15[/tex]
[tex]f(-3)=-84\neq 0[/tex]
At x=-1,
[tex]f(-1)=(-1)^3-3(-1)^2+5(-1)-15[/tex]
[tex]f(-1)=-1-3-5-15[/tex]
[tex]f(-1)=-24\neq 0[/tex]
At x=1,
[tex]f(1)=(1)^3-3(1)^2+5(1)-15[/tex]
[tex]f(1)=1-3+5-15[/tex]
[tex]f(1)=-12\neq 0[/tex]
At x=3,
[tex]f(3)=(3)^3-3(3)^2+5(3)-15[/tex]
[tex]f(3)=27-27+15-15[/tex]
[tex]f(3)=0[/tex]
Since, the value of given function is 0 at only x=3, therefore 3 is a root of given function.
Hence, the correct option is D.

Wallace recorded the length of his paintings in feet. Which list shows the lengths in order from greatest to least? List 1: 4.5 feet, 4 feet, 3.99 feet, 3.5 feet, 4.25 feet List 2: 3.99 feet, 4.25 feet, 4.5 feet, 3.5 feet, 4 feet List 3: 4.5 feet, 4.25 feet, 4 feet, 3.99 feet, 3.5 feet List 4: 3.5 feet, 3.99 feet, 4 feet, 4.25 feet, 4.5 feet
Answer:
list 3
Step-by-step explanation:
if you look at list 3 "4.5 feet, 4.25 feet, 4 feet, 3.99 feet, 3.5 feet" you can easily see that it is going from greatest to smallest because 4.5 is larger than 4.25 and 4.25 is larger than 4 and 4 is larger that 3.99 by 0.01 as you see its only 0.01 diffrence but it is still larger

Answer:
y=-1/4x+3
Step-by-step explanation:
put it into y-y1=m(x-x1) form, which gives you y+3=-1/4x(x+0)
(side note: we change the y- to a y+ becuase the y in the point in negative. another side note, the slope is -1/4x because perpendicular slopes are opposite, in this case 4x (or 4/1x) is the opposite of -1/4 x)
then remove the parenthesis. y+3=-1/4x
then isolate y and balance the equation.
y+3-3=-1/4x-3
this gives you the answer of y=-1/4x-3.
Answer:
y=-2x-3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=x2−2.
The slope of the perpendicular line is negative inverse: m=−2.
So, the equation of the perpendicular line is y=−2x+a.
To find a, we use the fact that the line should pass through the given point: −3=(−2)⋅(0)+a.
Thus, a=−3.
Therefore, the equation of the line is y=−2x−3.
Answer: y=−2x−3.

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella's strategy is incorrect?
Answer:
Step-by-step explanation:
Given the equation
4x-2(3x-4)+4 = -x+3(x+1)+1
Open the parenthesis on both sides
4x-6x+8+4 = -x+3x+3+1
-2x+12 = 2x+4
Collect like terms
-2x-2x = 4-12
-4x = -8
Divide both sides by -4
-4x/-4 = -8/-4
x = 2
Hence the value of x is 2
