Answer:
no
Step-by-step explanation:
The measures 14, 18, 33 cannot correspond to the sides of a triangle. The two short sides total 32 in length, so cannot meet up with the ends of the side whose length is 33. A triangle cannot be formed.
A bicycle wheel with radius 26" rotates through an arc that measures 80°. What is the length of the arc of the tire that touched the ground? 5.78 inches 11.56 inches 2.88 inches
Answers
Answer:
104/4 pi
Step-by-step explanation:
Answer: The circumference of a circle is:
Radius = r, Diameter = d, C = Circumference
C=2πr (as 2r=d)
C=πd
-------------
If the radius of the circle is 26" then its diameter must be 52".
This means that the bicycle wheel has a circumference of 52π".
I'm going to divide 52π" into 360 parts (because a circle is made up of 360 degrees). I'll then multiply this value by 80 to give you an answer.

Answer:
II only
Step-by-step explanation:
You can simplify the inequality like this:
3 -8 > 8 -8 + 5x . . . . . . . . subtract 8 from both sides
-5 > 5x . . . . . . . . . . . . . simplify
-5/5 > (5x)/5 . . . . . . . divide both sides by 5
-1 > x . . . . . . . . . . . . simplify
I find this easier to compare to a numbers on a number line if the inequality symbol points to the left. (This is a personal preference. YMMV)
x < -1
Now, we can see that only numbers to the left of -1 on the number line will be suitable values for x. Of those listed, only -9 is a solution.

Which statement regarding the diagram is true?
mMKL+mMLK=mJKM mKML+mMLK=mJKM mMKL+mMLK=180 mJKM+mMLK=180
Answers
Answer:
mKML+mMLK=mJKM
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are scalene, acute, obtuse, equilateral, isosceles, and right triangle.
As shown in the diagram, polygon MLK is a triangle. The sum of angles in a triangle is equal to 180°, hence:
m∠MLK + m∠KML + m∠MKL = 180° (sum of angles in a triangle).
m∠MKL = 180 - (m∠MLK + m∠KML) (1)
Also along line JL, the sum of angles on one side of a straight line is 180°, therefore:
m∠JKM + m∠MKL = 180° (sum of angles in a straight line)
m∠JKM + m∠MKL = 180° (2)
From equations 1 and 2, equating give:
m∠JKM + [180 - (m∠MLK + m∠KML)) = 180
m∠JKM + 180 - m∠MLK - m∠KML = 180
m∠JKM = m∠MLK + m∠KML

etermine whether the given description corresponds to an observational study or an experiment. In a study of 444 women with a particular disease, the subjects were photographed daily. Does the given description correspond to an observational study or an experiment?
Answers
Answer:
observational study
Explanation:
The above is an example of observational study. An observational study merely observes and takes note, it does not try to interfere or intervene with the sample by deciding who would be exposed or not exposed to a certain explanatory variable(such as a disease). On the other hand, the experimental study divide up samples into groups, having the experimental group and the control group. This way the researcher interfers with the sample: The experimental group being the group exposed to the independent/explanatory variable while the other/control group is not.

Assume that a three-month CD purchased for $3000 pays simple interest at an annual rate of 10%. How much total interest does it earn?
$ ____
What is the balance at maturity? ______
Answers
Answers:
interest = $75balance at maturity = $3075=============================================================
Explanation:
The simple interest formula is
i = p*r*t
where in this case,
p = 3000 = principal (amount deposited)r = 0.10 = annual interest rate in decimal formt = 3/12 = 0.25 = number of yearsSo,
i = p*r*t
i = 3000*0.10*0.25
i = 75 is the amount of interest earned
This adds onto the initial deposit to get the final balance when the CD matures (ie when you're able to withdraw the money without penalties)
The balance at maturity is p+i = 3000+75 = 3075 dollars
---------------
In short, you deposit $3000 into the CD and have to wait 3 months for the amount to update to $3075.

A box has dimensions of 4.0 cm by 8.5 cm by 2.0 cm. The volume of the box in mL is:
Answers
Step 1: Write volume formula
The formula for volume is often abbreviated into V=l×w×h. This stands for volume= length×width×height.
Step 2: Substitute numbers for answer in cm
To get the answer in cm, simply substitute the numbers into the equation. Then, you may simply multiple them to solve.
V=4.0 cm×8.5 cm×2.0 cm
V= 68 cm
Step 3: Add cubed symbol
Since this is referring to volume, you will need to add the cubed symbol to the end of your answer. This will appear as a number 3 above the cm on the right side.
Step 4: Convert to mL
This is a simple step once you understand the formula to convert. Luckily for us, cm cubed (cm3)= 1 mL. Because of this, the answer will remain as 68 mL
Hope this is right and it helps you!
From the observation deck of a skyscraper,
Taylor measures a 67° angle of depression
to a ship in the harbor below. If the
observation deck is 1014 feet high, what is
the horizontal distance from the base of the
skyscraper out to the ship? Round your
answer to the nearest tenth of a foot if
necessary.
Answers
Given:
Angle of depression from observation deck to a ship = 67°
Height of observation deck = 1014 feet.
To find:
The horizontal distance from the base of the skyscraper out to the ship.
Solution:
Let x be the horizontal distance from the base of the skyscraper out to the ship.
Using the given information draw a diagram as shown below.
In a right angle triangle,
[tex]\tan\theta=\dfrac{Perpendicular}{Base}[/tex]
For triangle ABC,
[tex]\tan A=\dfrac{BC}{AB}[/tex]
[tex]\tan (67^\circ)=\dfrac{1014}{x}[/tex]
[tex]x=\dfrac{1014}{\tan (67^\circ)}[/tex]
On further simplification, we get
[tex]x=\dfrac{1014}{2.35585}[/tex]
[tex]x=430.41789[/tex]
[tex]x\approx 430.4[/tex]
Therefore, the horizontal distance from the base of the skyscraper out to the ship is 430.4 feet.
Applying the Trigonometry ratio, TOA, the horizontal distance from the base of the skyscraper out to the ship is: 430.4 ft.
Recall:
To solve a right triangle, apply any of the Trigonometry ratios, SOH CAH TOA, where necessary.The situation described is shown in an image attached below, where:
BA = horizontal distance from the base of the skyscraper out to the ship (adjacent side length)BC = 1014 ft (Opposite side length)∠A = 67° = reference angle (∅)To find BA, apply TOA, which is:
tan ∅ = Opp/Adjacent
Substitutetan 67 = 1014/BA
[tex]BA = \frac{1014}{tan(67)} \\\\\mathbf{BA = 430.4 $ ft}[/tex]
Therefore, applying the Trigonometry ratio, TOA, the horizontal distance from the base of the skyscraper out to the ship is: 430.4 ft.

QUESTION 6 The scale on a map is given as 1 : 320,000. If the distance between the top of the two mountains on the map is 6.8cm, what is the actual distance in kilometres between the two tops of the mountain. ? show working out to prove answer.
Answers
Answer:
The actual distance is of 21.76 kilometers.
Step-by-step explanation:
Scale problems are solved by proportions, using a rule of three.
The scale on a map is given as 1 : 320,000
This means that each unit on the map represents 320,000 units of distance.
Distance between the top of the two mountains on the map is 6.8cm
Then
1 cm - 320,000 cm
6.8 cm - x
Applying cross multiplication:
[tex]x = 6.8*320000 = 2176000[/tex]
Distance in kilometers
To convert from centimeters to kilometers, we divide by 100000. So
2176000/100000 = 21.76
The actual distance is of 21.76 kilometers.

Let X denote the number of bars of service on your cell phone whenever you are at an intersection with the following probabilities.
x 0 1 2 3 4 5
P(X=x) 0.1 0.15 0.25 0.25 0.15 0.1
Determine the following probabilities
a. Two or three bars
b. At least one bar
c. Fewer than two bars
d. More than three bars
Answers
Answer:
a. [tex]P(2 \leq X \leq 3) = 0.5[/tex]
b. [tex]P(X \geq 1) = 0.9[/tex]
c. [tex]P(X < 2) = 0.25[/tex]
d. [tex]P(X > 3) = 0.25[/tex]
Step-by-step explanation:
We are given the following distribution:
[tex]P(X = 0) = 0.1[/tex]
[tex]P(X = 1) = 0.15[/tex]
[tex]P(X = 2) = 0.25[/tex]
[tex]P(X = 3) = 0.25[/tex]
[tex]P(X = 4) = 0.15[/tex]
[tex]P(X = 5) = 0.1[/tex]
a. Two or three bars
[tex]P(2 \leq X \leq 3) = P(X = 2) + P(X = 3) = 0.25 + 0.25 = 0.5[/tex]
Thus:
[tex]P(2 \leq X \leq 3) = 0.5[/tex]
b. At least one bar
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1 = 0.9[/tex]
Thus:
[tex]P(X \geq 1) = 0.9[/tex]
c. Fewer than two bars
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.15 = 0.25[/tex]
Thus:
[tex]P(X < 2) = 0.25[/tex]
d. More than three bars
[tex]P(X > 3) = P(X = 4) + P(X = 5) = 0.15 + 0.1 = 0.25[/tex]
Thus:
[tex]P(X > 3) = 0.25[/tex]
