Answer:
the shape of the box is a rectangular prism.The way to solve this is by using the formula V=l*w*h
we only have 20(l) and 10(h) so here's a clue it said that the base of the box was squared so the width would also be 10 in. so....
V=20*10*10

Answer:
x = 91
Step-by-step explanation:
y = 130
The supplementary angle with y is 50
z = 321
360 - 321 = 39
Interior angles:
50 and 39 and x
To find x:
x + 50 + 39 = 180
x + 89 = 180
x = 180 - 89
x = 91

Answer:
An example of complementary angles would be Angle FA and Angle EF
Step-by-step explanation:
These angles add up to 90 degrees
Hope this helps!
Answer:
∠AGF and ∠FGE, or ∠BGC and ∠CGD
Explanation
complementary angles are any angles which add up to 90°. since ∠AGB is a right angle according to the diagram, and AGD as well as BGE are straight lines (assumption), ∠DGE is also equivalent to 90° (opposite angles).
thus, the sum of ∠AGE and ∠BGD would be 90° each, so we know that ∠AGF and ∠FGE or ∠BGC and ∠CGD each add up to 90°.

In the data set below, what is the mean absolute deviation? 38147 If the answer is a decimal, round it to the nearest tenth. mean absolute deviation (MAD):
Answer:
2.32
Step-by-step explanation:
Given the data:
3, 8, 1, 4, 7
The mean absolute deviation (MAD) :
Σ|x - m| / n
Mean, m = Σx / n
Σx = 23
n = 5
Mean, m = 23 / 5 = 4.6
|3 - 4.6| + |8 - 4.6| + |1 - 4.6| + |4 - 4.6| + |7 - 4.6|
(1.6 + 3.4 + 3.6 + 0.6 + 2.4) / 5

What is the volume, in cubic in, of a rectangular prism with a height of 9in, a width of 4in, and a length of 5in?
Answer:
The volume is 180 in
Step-by-step explanation:
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container;

As the number of surveys conducted increases, the average of the sample means approaches the population mean.
Step-by-step explanation:
Plato
The average of the sample mean from the given data values in the table is gotten as; 14.98
How to find the average of mean?
When finding the average, we need to sum up all the given data and then divide by the total number of data.
The given data values are; 15.09, 14.45, 14.91, 15.09, 14.91, 15.82, 14.36, 15.55, 14.36, 15.27.
The sum of these given data is;
15.09 + 14.45 + 14.91 + 15.09 + 14.91 + 15.82 + 14.36 + 15.55 + 14.36 + 15.27 = 149.81
Thus;
Average of sample mean = 149.81/10
Average = 14.98

Answer: y = -2x + 6
Slope-intercept form: y = mx + b, where m = slope and b = y-int
m = -2
(-1, 8) --> -1 = x₁, 8 = y₁
Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:
y - 8 = -2[x -(-1)]
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6
The sun causes changes to things on Earth. Think of an object you have observed before and after it was left out in the sun. Describe how it changed.
Answer: well i have put things like leather and it shrunk while it was out in the sun
Step-by-step explanation:
We want to study how the Sun affects things on Earth, I will give you two examples.
First, we know that the Sun radiates electromagnetic energy.
So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.
The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).
Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.
So these are just two different examples of how the Sun affects things on Earth.

The first cube has a side length of 3 units. The second cube has a side length of 5 units. Write an expression that you can use to find the total volume of ice you can make.
Answer:
152 cubic units
Step-by-step explanation:
Volume of a cube = L³ where;
L is the side length of a cube
For the cube of side length of 3 units
Volume of the cube = 3³
Volume of the cube = 27 cubic units
For the cube of side length of 5 units
Volume of the cube = 5³
Volume of the cube = 125 cubic units
Total volume the ice can make = (125 + 27)cubic units
Total volume the ice can make = 152 cubic units

Add the polynomial expressions using the horizontal format.
(6x3 + 5x) + (4x3 + x2 - 2x + 9)
Answer:
I'll clear the parentheses first. This is easy to do when adding, because there are no "minus" signs to take through any parentheticals. Then I'll group the like terms in accordance to their variables (keeping them in alphabetical order), and finally I'll simplify:
(2x + 5y) + (3x – 2y)
2x + 5y + 3x – 2y
2x + 3x + 5y – 2y
5x + 3y
These two terms are un-like (because they have different variables), so I cannot combine them. This means that I've gone as far as I can, so my hand-in answer is:
5x + 3y
