A bridge is 3911.1 meters long. Which of the following best describes the length of the bridge in kilometers?
Answer:
3.9111 km
Explanation:
The length in kilometers is equal to the meters divided by 1,000. So, if you divide 3911.1 by 1,000 that equals 3.911. You move the decimal point to the left 3 times based on the number of zeros.

Answer:
4) 6 students
5) 7 fewer students
6) No, you can not tell from the frequency table how many students ran a mile in exactly 12 minutes.
Step-by-step explanation:
4) you’d look at the row from 8:00-8:59.
5) Add the first two rows together (6+2=8), then subtract that by the sum of the last two rows (9+6=15), which is 7
6) There’s no pattern in the frequency table, and the data points would be plotted differently since it’d be from a range of times, not one set time.
Hope this helped, sorry if I’m wrong on #6 ;)

PLEASE HELP, I need this test done and something not failed. I dont understand.
Answer:
XVW and WVT
Step-by-step explanation:
Two angles are supplementary angles when the sum of their measures is equaled to 180 degrees.
180 degrees = a line.
YVZ and WVU are Vertical Angles
YVZ and ZVT are not straight lines together.
XVW and WVU are on the same straight line but you have to add UVT in order to get 180.
XVW and WVT are the only ones that look like they can add up to 180 degrees.
XVW and WVT should be the answer, I really hope this helps!
If the scale factor between a scale drawing of a rectangle and the real object is 1:3 what would be the ratio of the areas?
Answer:
The ratio of the areas will be will be 1 : 9
Step-by-step explanation:
The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.
The linear scale factor is quite different from the area scale factor but related to it in the following way:
The area factor can be obtained by squaring the linear scale factor.
This is Area factor = (Linear scale factor) ^2.
Linear scale factor = (1:3)
Area factor = [tex]1^2 : 3^2[/tex]
Area factor will be 1: 9
Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9
f(x)=6^x for x=2 help please
9514 1404 393
Answer:
f(2) = 36
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 6^2
An exponent of 2 means 6 is a factor two times.
f(2) = 6×6
f(2) = 36
Answer:
36
Step-by-step explanation:
To evaluate f(x) = 6^x at x = 2, substitute 2 for x:
f(2) = 6^2 = 36

solve by substitute. 9y+8=x. -2x+8y=-36
Answer:
Let's solve for x.
9y+8=x
Step 1: Flip the equation.
x=9y+8
Answer:
x=9y+8
Let's solve for x.
−2x+8y=−36
Step 1: Add -8y to both sides.
−2x + 8y + −8y = −36 + −8y
−2x = −8y − 36
Step 2: Divide both sides by -2.
−2x / −2 = −8y − 36 / −2

Answer:
(26, 2)
x = 26
y = 2
Step-by-step explanation:
Given:
9y + 8 = x
-2x + 8y = -36
Substitute (9y + 8) for x in the second equation.
-2(9y + 8) + 8y = -36
Then distribute and solve.
-18y + (-16) + 8y = -36
Combine like terms.
-10y - 16 = -36
-10y = -20
y = 2
Solve for x by substituting the y value (2) into 9y + 8 = x.
9(2) + 8 = x
18 + 8 = x
x = 26
Therefore, the solution is (26, 2) in terms of (x, y).
Assume that lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
9514 1404 393
Answer:
x = 20, or 125
Step-by-step explanation:
We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.
__
The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.
x° = 90° -70°
x = 20
__
If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...
x° = 180° -(180° -70°)/2 = 90° +70°/2
x = 125
To find the area of a triangle, you can use the expression b × h ÷ 2, where b is the base of the triangle and h is its height. What is the area of a triangle with a base of 2 and a height of 8?
The area of the triangle is....?

Show Your Work
Answer:
\bold{\text{Slope (m)}=\dfrac{1}{4}}Slope (m)=41
Step-by-step explanation:
A linear equation is of the form: y = mx + b where
m is the slope
b is the y-intercept (where it crosses the y-axis)
x + 4y = 16
4y = -x + 16
y = -\dfrac{1}{4}x+\dfrac{16}{4}y=−41x+416
y=-\dfrac{1}{4}x+4y=−41x+4
The y-intercept (b) = 4
Next, find the slope given point (4, 5) and b = 4
\begin{gathered}y=mx+b\\\\5=m(4)+4\\\\1=4m\\\\\dfrac{1}{4}=m\\\\\\\\\large\boxed{Slope (m)=\dfrac{1}{4}}\end{gathered}y=mx+b5=m(4)+41=4m41=mSlope(m)=41
A sweater is on sale for 12% off. The sale price is $44.00. What is the original amount of the sweater?
==================================================
Work Shown:
x = original price
y = sale price
d = discount = amount saved
d = 12% of x = 0.12x
y = x - d = x - 0.12x = 0.88x
Note how 0.88 = 88%, and this represents the percentage you have to pay if you get 12% off.
We're told the sale price is y = 44, so this leads to...
y = 0.88x
44 = 0.88x
0.88x = 44
x = 44/0.88
x = 50
The original price was $50
---------------------
Check:
If the original price was $50, then the amount you save is 0.12*50 = 6 dollars, which is the discount.
The sale price is 50-6 = 44 dollars which matches up with what your teacher gave you. The answer is confirmed.
12. The tomb of Gunbad-Kabud in Maragheh, Iran is the shape of a decagonal tower and has a side length of approximately 8 feet. Determine the distance from the center of the tomb to the outside wall.
Answer:
The distance would be 12.31073415. Rounded, 12.31
Step-by-step explanation:
First off, we know a decagon has 10 sides. Secondly, it is given that the total side length is 8 feet- split in half it's 4 and 4 (this will come into play in the formula). Next, we want to find the angle measure of one of the isosceles triangles. Thus, do 360/10 which gives 36. Then do 36/2 which equals 18. This is the angle measure we need. Now that we have the necessary information, we can set up the formula. Following SOHCAHTOA, we can see that we need to use the tangent to find the apothem since our opposite side length of 4 is given. Set up the equation like so: tan18 = 4/a. When plugged in and solved, the answer of 12.31073415 is received.
I hope that helped!
