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?"

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.
Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.
Answer:
Non-mutually exclusive
Step-by-step explanation:
both events can happen simultaneously... 3 is an odd number, events A and B have a common outcome.
It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.
===================================================
Explanation:
Ask yourself "is it possible to get a 3 and an odd number at the same time?"
The answer is "yes, because 3 is an odd number"
This is why they are non-mutually exclusive.
Mutually exclusive events cannot happen at the same time. In terms of a venn diagram, mutually exclusive events would be represented by two circles that do not overlap. The overlapping region is where the two events happen at the same time. An example of mutually exclusive events would be flipping a single coin to land on heads and tails at the same time.

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

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.

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!
Jade's work:
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

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

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]

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

The slope can be found with two sets of points
The points can be any points, but in this case I choose the point (-1,10) and (1,2)
Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{10-2}{-1-1} =\frac{8}{-2} =-4[/tex]
The slope of the line that contains these points is -4.
