Answer:
16 degrees
Step-by-step explanation:
This is a right triangle with shorter leg 3 in and hypotenuse 11 in. The 3 in side is opposite the angle theta. Thus, by definition of the sine function,
sin theta = 3/11 = 0.273
Using a calculator and the inverse sine function, we get theta = 0.276 radian, or 15.8 degrees. This rounds up to 16 degrees.

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
Multiple choices

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
= 2.32
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;

I NEED HELP PLEASE TRYING TO PASS SCHOOL PLEASE ASAP NEED HELP
Answer:
The answer is...
Step-by-step explanation:
220 - 50 is 170. So know you know how much money he wants plus to his salary. 170/5 is 34.
x=34
Answer:
5x + 50 ≥ 220
5x ≥ 220 - 50
Step-by-step explanation:
The at least inequality sign for 220 is: ≥ 220
5x + 50 ≥ 220
5x ≥ 220 - 50
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

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°.

Answer:
388 in²
Step-by-step explanation:
(10)(19) + (11)(18) = 388 in²
Answer:
388 in²
Step-by-step explanation:
The upper rectangle (the big one) is 30 in long and 10 in wide. Thus, its area is the product of these two measurement: 300 in².
The lower rectangle is 8 by 11 inches, or 88 in²
The total area of the figure is 388 in²
In the rectagular prism shown below, GH is parallel to EF. If the equation of GH is 6y-x=2, could the equation of EF be 4=y-1/6x? Explain your reasoning.
Answer:
Yes
Step-by-step explanation:
Given
GH:
[tex]-6y - x = 2[/tex]
Required
Can EF be
[tex]4 = y - \frac{1}{6}x[/tex]
First, we determine the slope of GH
[tex]-6y - x = 2[/tex]
Solve for 6y
[tex]6y = -x - 2[/tex]
Solve for y
[tex]y = -\frac{1}{6}x - \frac{2}{6}[/tex]
[tex]y = -\frac{1}{6}x - \frac{1}{3}[/tex]
An equation has the form:
[tex]y =mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m = -\frac{1}{6}[/tex]
Next, determine the slope of EF
[tex]4 = y - \frac{1}{6}x[/tex]
Make y the subject
[tex]y = -\frac{1}{6}x + 4[/tex]
The slope is:
[tex]m = -\frac{1}{6}[/tex]
Compare the slopes of both lines.
[tex]m=m = -\frac{1}{6}[/tex]
Since they have the same slopes, then the equation of EF is possible

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
