Which equation is an identity
A man travels 2 miles, turn left and travels 3 miles, turn left again and travel 6 miles. How far is he from the starting point?
Answer: 5 miles
Step-by-step explanation:
this creates a polygon which can be shortened to be a triangle with side lengths 3 and 4 and the hypotenuse unknown. to find the side length you use the formula a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
sqrt(25) = c
c = 5
Describe and correct the error in solving the equation.
27 = n-15
-15 +15
12 = n
help please? anyone?
Answer:
"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "
Step-by-step explanation:
Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.
= 8.8 squared + 9 squared = c squared
= 77.44 + 81 = c squared
[tex]\sqrt{158.44}[/tex] = c squared
c squared = (rounded) 12.6 ft
which of these ARE NOT equivalent?

Work out size of Angle x
Answer:
106
Step-by-step explanation:
all 3 of the angles add up to 360
you already know one is 164 and one is a right angle so
164 + 90 = 254
360 - 254 = 106

Answer:
9. C, II and III.
10. The correct answer is 944 cubic mm, as far as I can tell. I double checked my formulas and calculations. You can copy the formulas/calculations below and email your teacher. I have tried to figure out how they got the numbers they have. The best guess I can come up with is that they used 6 as the diameter of the cylinder, using 3 for the radius. That gets us closer, at 749 cubic mm, but not quite there.
Step-by-step explanation:
9. If the cylinder is standing upright, the horizontal cut would be a circle or oval, and the vertical cut could be a rectangle
10. First we'll get the volume of the base rectangle. Then we'll calculate the volume of a cylinder, then divide that part in half, because it's 1/2 a cylinder on top of a rectangular prism.
Volume of a rectangular prism:
V = (length)(width)(height)
= 11 x 9 x 6 = 594 cubic mm
Volume of a cylinder:
V = (pi)(radius)^2(height)
The radius = 1/2 the diameter of the circle...the diameter is 9, so the radius is 4.5
= (3.14)(4.5)(4.5)(11)
= 699.435
That would be for a full cylinder with radius 4.5 and height of 11. We have half of one, so 699.435/2 = 349.7175 cubic mm
Add the volume of the 1/2 cylinder to the volume of the rectangular prism:
349.7175 + 594 = 943.7175, rounded = 944...which is none of your answers :/

Celeste used 20 inches of ribbon from a spool that holds 36 inches of ribbon. What is the decimal equivalent for the amount of ribbon Celeste uses.
Answer: 0.56
Step-by-step explanation:
The spool holds a total of 36 inches of ribbon and out tis amount, Celeste used 20 inches of ribbon.
Celeste therefore used 20 / 36 of the ribbon available from the stool.
In decimal this is:
= 20 ÷ 36
= 0.5556
= 0.56

Is it possible to create a line segment with "infinite

Answer:
No, it is not possible
Step-by-step explanation:
Required
Is it possible to have a line segment with: [tex]m = \infty[/tex]
To answer this question, we will interpret the steepness as slope.
So, we have:
[tex]m = \infty[/tex]
The interpretation of a line with: [tex]m = \infty[/tex] is:
It starts from (x,y_1) and ends at (x,y_2)
When the slope (m) is then calculated, we have:
[tex]m = \frac{y_2 - y_1}{x_1 - x_1}[/tex]
[tex]m = \frac{y_2 - y_1}{0}[/tex]
[tex]m = \infty[/tex]
What this means is that, the line has no end points.
A line segment as described here means a line that has endpoints (i.e. a finite starting point and a finite finish point)
So, we've established that: [tex]m = \infty[/tex] means no endpoints and a line segment has end points, then we can conclude that it is not possible to create a line segment with [tex]m = \infty[/tex]
Steepness of a line is the rise or fall of it at a sharp angle.The Is it not possible to create a line segment with infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.
Steepness-Steepness of a line is the rise or fall of it at a sharp angle. The slope of the line describe the steepness of a line.
Infinite steepness-A infinite steepness refers to a vertical line on the graph. When the line with infinite steepness plotted on the graph it is only parallel to the y axis. The change on the x axis is zero and does not move in the x axis, when a line has infinite steepness.
To understand it better suppose a line is passed through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] points. For such line the slope of the line can be given as,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1} [/tex]
The line with infinite steepness does not move in the x axis. The coordinate of the x axis same for the line. Thus,
[tex]x_2=x_1[/tex]
The slope for such line is,
[tex]m=\dfrac{y_2-y_1}{x_1-x_1} [/tex]
[tex]m=\dfrac{y_2-y_1}{0} [/tex]
[tex]m=\infty[/tex]
Thus the slope of the line is infinite. But the line With no finite point is not possible to plot.
Hence the Is it not possible to create a line segment with "infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.

write an equation for the line that is parellel to the given line and that passes through the given point?
y = 2x + 7; (3, 11)
a.y = 2x – 19
b.y=1/2x+5
c.y= -1/2x-5
d.y = 2x + 5
Answer:
y = 2x + 5 (answer d)
Step-by-step explanation:
Parallel lines have the same slope, and thus, if we're given y = 2x + 7, we know that the slope of the 'new' line is 2. This 'new line' passes through (3, 11). Begin with the point-slope formula y - k = m(x - h) and substitute 3 for h, 11 for k and 2 for m:
y - 11 = 2(x - 3)
Rewriting this in slope-intercept form, we get:
y = 2x - 6 + 11. or y = 2x + 5 (answer d)

Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? Show your work.
The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.
