Check the picture below.
the distances d1 and d2 are for this ellipse 7 and 3 respectively, keeping in mind that their sum is always the same, namely d1 + d2 is always the same 10 no matter where on the ellipse you move the point, notice in the picture, if we move d1 to the extent that lies flat right on top of d2, we have the length of d1 in purple, plus the length of d2, which we later colored in darkyellow, if we move d2 to the right-hand-side or the tail of d1, we'd end up with the ellipse's major axis, which is oddly enough, d1 + d2.

A student adds 10 grams of four different powdered solids into four different beakers. The student then adds 100 mL of water to each beaker, stirs the mixtures, and allows them to sit for half an hour before recording observations. Which question is the student most likely trying to answer with this investigation?
Answer:
Which substance dissolves in water?
Step-by-step explanation:
The student adds the same amount of substance of different types i.e., 10 grams to each beaker and the same amount of water i.e., 100 mL to each beaker. All of them are stirred and observations are taken down at the end of thirty minutes.
That is all that is mentioned in the question. The student is most likely measuring which substance dissolves in water. As all the other variables are kept constant.
So, the student here is most likely trying to answer the question "Which substance dissolves in water?"

The perimeter of a rectangle is 40 units. The length of the rectangle, L, is 7 units.
Answer:
L=7
W=13
Perimeter=40
Area=91
Step-by-step explanation:
Perimeter = 2L+2W
40=2(7)+2W
40=14+2W
-14 -14
26=2W
Divide both sides by 2
13=W
Area=L x W
7 x 13 = 91
Answer:
length = 7 units
width = 13 units
area = 91 square units
perimeter = 40 units
Step-by-step explanation:
What is the area of a rectangle?
❖ The area of a rectangle can be found by multiplying the length and
width of the rectangle.
What is the perimeter of a rectangle?
❖ The perimeter of a rectangle is the sum of all sides- length and
width. In this case, we're given the perimeter as 40 units and the
length as 7 units, but the width is unknown. Formula to find
perimeter of rectangle is 2(l + w) = P.
Solving for Width
[tex]40=2(7+w)[/tex] [tex]40=14+2w[/tex] [tex]26=2w[/tex] [tex]w=13[/tex]Solving for Area

Answer:
Step-by-step explanation:
The first bolt he buys has length 3/4 in plus 1/8 in, which comes out to
6/8 + 1/8 inch, or 7/8 inch.
The second bolt length cannot be determined using the information given: "3/4 - inch shorter." Ensure that you have copied down this probjem completely and accurately.
What is the standard form of the following equation? 4x2 + 9y2 + 24x – 36y + 36 = 0
Answer:
[tex]\frac{ (x+3)^2}{9} + \frac{ (y-2)^2}{4} =1[/tex]
-step explanation:
The standard form of the given equation was reduced, representing an ellipse.
The given equation is:
[tex]4x^{2} +9y^{2} +24x-36y+36=0[/tex]
What is an equation?An equation is a statement that equates to two expressions.
We know the above equation represents an ellipse.
Rearranging the given equation
[tex]4x^{2} +24x+9y^{2} -36y+36=0[/tex]
[tex]4(x^2+6x)+9(y^{2} -4y)+36=0[/tex]
[tex]4(x^2+6x+9)+9(y^{2} -4y+4)=36[/tex]
[tex]4(x+3)^2+9(y-2)^2=36[/tex]
[tex]\frac{4(x+3)^2}{36}+\frac{9(y-2)^2}{36} =1[/tex]
[tex]\frac{(x+3)^2}{9}+\frac{(y-2)^2}{4} =1[/tex], which is the standard form of the given equation.
Hence, the standard form of the given equation was reduced.

Santiago's Snow Globes designs custom snow globes. To ship a recent large order, Santiago's Snow Globes first packed individual snow globes in cube-shaped boxes with edges 6 inches long. The boxes were packed into a larger shipping container until it was completely full. The shipping container is shaped like a rectangular prism that is 24 inches long, 24 inches wide, and 30 inches tall
The number of boxes packed to fill the rectangular prism shaped container is: 80 boxes.
What is the Volume of a Rectangular Prism?Volume = length × width × height.
Find the volume of one cube-shaped box:
Volume = 6 × 6 × 6 = 216 in³
Find the volume of one rectangular prism:
Volume = length × width × height = 24 × 24 × 30 = 17,280 in³.
Number of boxes packed to fill the rectangular prism shaped container = 17,280/216 = 80 boxes.

Answer:
1. 2(2w + w)
2. 2(2w) + 2(w)
Step-by-step explanation:
The formula to find the perimeter of a rectangle is [tex]2(l+w)[/tex], and we can easily apply it with this rectangle as 2(2w + w).
You can find another expression by simplifying 2(2w + w), which is 2(2w) + 2(w).
A system of linear equations is given by these equations 3y-2x=-9 y=-2x+5 The solution to this system is
Answer:
(3, -1) or x=3, y=-1
Step-by-step explanation:
using substitution for y, the first equation becomes 3(-2x + 5) - 2x = -9
distribution of the 3 gets your equation to be -6x + 15 - 2x = -9
from here you combine like terms to get -8x + 15 = -9
from here it's just a two step equation
subtract 15 from both side to get -8x = -24
divide and get x = 3
substitute x in the equation for y to get y = -2(3) + 5
distribution gets you y = -6 + 5, which makes y = -1
to check your work you can just plug in the variables equivalents in the first equation, which upon doing you can see that the answer is indeed 3, -1

Write an equation for the line in slope-intercept form.
Answer:
y=2x+2
Step-by-step explanation:
the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2

Sense or nonsense Peter and Jade are using what they know about properties to write an expression equivalent to 2×(n+6)+3 whose answer makes sense? Whose answer is nonsense? Explain your reasoning.
Answer:
Jade's work makes sense, Peter's does not.
Step-by-step explanation:
What's wrong with Peter's work:
Peter did not apply associative property correctly. You cannot change what is inside the parenthesis. He also shouldn't be using associative property to solve this equation because it just doesn't make sense!

She applied distributive property correctly and multiplied each term in the parenthesis by 2. All of her processes are logical and make sense! I could go on, but everything is correct lol
