Answer:
-16/3 = x
Step-by-step explanation:
3(x – 2) + 4x = 10(x + 1)
Distribute
3x -6 +4x = 10x+10
Combine like terms
7x-6 = 10x+10
Subtract 7x from each side
-6 = 3x+10
Subtract 10 from each side
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 = x
Answer:
x = -16/3

The volume of a cylinder is 576, cubic inches. The radius of the circular base is 4 inches. What is the height of the cylinder?
Answer:
36 / pi = h
Using 3.14 for pi
h =11.46496815 inches
Using the pi button
h =11.45691559 inches
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume and the radius
576 = pi ( 4)^2 h
576 = pi 16 h
Divide each side by 16 pi
576/16 pi = pi 16 h/ 16 pi
36 / pi = h
Using 3.14 for pi
h =11.46496815 inches
Using the pi button
h =11.45691559 inches
Which phrase best describes the figure?
A- concave nonagon
B- convex octagon
C- convex nonagon
D- concave octagon
Answer:
Hi there!
The correct answer is: B. Convex Octagon
Step-by-step explanation:
The figure first classifies as an octagon because it has 8 sides.
Next you can tell whether or not it is concave or convex by remembering: concave has a "cave" in it.
Concave or Convex
A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave.
The given figure is convex octagon. Therefore, option B is the correct answer.
What is octagon?An octagon can be defined as a polygon with eight sides, eight interior angles, and eight vertices. When all the sides and angles of an octagon are equal in measurement, it is called a regular octagon.
Every polygon is either convex or concave. Convex octagons bulge outwards, whereas concave octagons have indentations (a deep recess). Convex octagons are those in which all the angles point outwards. A regular octagon is an example of a convex octagon. The octagon in which at least one of its angles points inwards is a concave octagon.
In the given figure, there are 8 sides and 8 angles.
Therefore, option B is the correct answer.

Does the equation represent a direct variation? If so, find the constant of variation.
4x -5y = 0
a. yes; k = -5 b. no c. yes; k = 4/5 d. yes; k = - 4
Answer:
4/5
Step-by-step explanation:
4x-5y=0
subtract 4x on both the sides
4x-4x-5y = 0-4x
-5y = -4x
divide by -5 on both the sides
-5y/-5 = -4x/-5
y =( 4/5 )x

answer in terms of .
A) 1447 mm
B)1687 mm
C) 3121 mm
D) 4567 mm
Answer:
Step-by-step explanation:
Volume of the hemisphere
V = 2/3π x r^3
= 144π cu. mm
Volume of the cone
V = 1/3π x r^2 x h
V = 168π cu. mm.
Volume of the composite figure
= 144π + 168π
= 312π cu. mm.

Triangle ABC, with the vertices at A(0,0) B(3,5) and C(0,5) is graphed on the set of axes shown below. Name the solid that is formed when triangle ABC is rotated continuously about side AC and state the radius of the solid
Answer:
Solid formed will be a CONE
Radius of the cone = 3 units
Step-by-step explanation:
Given points of a triangle are A(0, 0), B(3, 5) and C(0, 5).
Given triangle is a right triangle.
When the given triangle ABC is rotated about a line AC, a 3D image of a solid will be created in the form of a CONE.
This cone will have the radius = BC
Length of side BC = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
= [tex]\sqrt{(3-0)^2+(5-5)^2}[/tex]
= 3
Therefore, radius of the cone = 3 units

PLEASE HELP! A survey was done that asked people to indicate whether they preferred pool swimming or ocean swimming. The results of the survey are shown in the two-way table.

Divide 239 by 609.
Subtract 185 from 609, then divide by 609.
Divide 185 by 609.
Add 239 to 609, then divide by 609.
Answer:
C
Step-by-step explanation:
I think the answer is C,
since to find the relative frequency, you divide the specific frequency
(in this case people over 30 who prefer ocean swimming, 185 people)
by the # of values total
(all values recorded, which in this case is the 609 peoples' surveys)
so, divide 185 by 609, which is C

Two parallel lines are crossed by a transversal. Parallel lines u and w are cut by transversal t. At the intersection of lines u and t, the bottom left angle is 105 degrees. At the intersection of lines w and t, the uppercase right angle is g degrees. What is the value of g? g = 75 g = 80 g = 100 g = 105
Answer:
I think it's 105.
Step-by-step explanation:
The wording is sort of unclear, but I drew it out and it seems that they are alternate interior angles. Alternate interior angles are congruent! If this is not the right answer, please tell me and I might be able to tell another one.
Well, technically, it has to be either 75 or 105, because all of the special relationships of triangles are either that they are supplementary or they are congruent. So if it's not 105, try 75 :)
The measure of the angle "g" is also equal to 105 degrees
Find the diagram attached below;
From the diagram, we can see that angle 105 and "g" are situated at the corner on both lines u and w.
This means that both angles are equal according to the alternate interior angle theorem, hence the measure of the angle "g" is also equal to 105 degrees

Identify which of the labeled angles in the figure is an obtuse angle. answers: A) 2 B) 3 C) 1 D) 4
Answer:
D) 4
Step-by-step explanation:
To start with we can see that on all the line there are little arrows on the end which means that the line continues forever.
C and B are acute angle because we can eyeball that they are less then 90 degrees.
A is most likely to be a right angle because their are two perpendicular straight lines.
D is the correct answer because as I said the lines continue forever. So in that case both lines are not perpendicular or less than 90º.

D

Solve the following equations using algebraic operations ( 4x-1=2x+11)
Answer:
x = 6
Step-by-step explanation:
4x-1=2x+11
Subtract 2x from each side
4x-2x-1=2x-2x+11
2x-1 =11
Add 1 to each side
2x-1+1 = 11+1
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
y=a(x-r)(x-s) what is a and r and s ?
Answer:
The constant a is the scale factor on the parabola; positive a makes a CUP (concave up), which is the usual orientation. Negative a makes an upside-down parabola. Big a (in absolute value) makes a skinny parabola, small a a wider one.
r and s are the zeros of the quadratic function, the values of x that give y=0.
Answer:
a , r, s , x all are variables
