Triangle MNO is similar to triangle PQR.
What is the value of x?
O A. 3.20 cm
OB. 3.48 cm
OC. 4.32 cm
OD. 4.83 cm
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{PR}{MO}[/tex] = [tex]\frac{PQ}{MN}[/tex] , substitute values
[tex]\frac{x}{7.2}[/tex] = [tex]\frac{6}{10}[/tex] ( cross- multiply )
10x = 43.2 ( divide both sides by 10 )
x = 4.32 → C

The value of a car with an initial purchase price of $12,250 depreciates by 11 percent per year
Answer:
It is decay because the value of the car keeps falling.
for example, the value next year, would be 12250 x (100% - 11%) = $10,902.50
If it were a growth, the value would increase yearly
12250 x (0.89)^time
Step-by-step explanation:
the equation to represent exponential decay = Amount x ( 1 - rate)^time

The data set represents the ages of students, in years, attending a robotics club meeting. What is the median age of the students in the club?
13, 15, 12, 12, 11, 16, 11, 13, 14, 12
Answer:
12.5
Step-by-step explanation:
put them in order from least to greatest: 11, 11, 12, 12, 12, 13, 13, 14, 15, 16
the middle is 12 and 13 so you do 12+13 then divide by 2
to get 12.5

Will had 64 baseball cards in his collection. He then got 8 more cards. He keeps the cards in a binder. Each page in the binder can hold 9 cards. Complete and solve the equations below to find how many pages of baseball cards Will has.
Answer: 64+8=72...72/9=8
Step-by-step explanation:
Rewrite the expression as a single logarithm:
log 80 - 3 log 2
Please help, thanks! Ok so, you pick a card at random, put it back, and then pick another card at random. There are FIVE cards and they are numbered like this: 1, 2, 3, 4, 5. What is the probability of picking a number greater than 1 and then picking a number less than 2? Write the answer as a fraction or whole number. Thank you!
Answer:
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5\}[/tex]
[tex]n(S) = 5[/tex]
Required
[tex]P(x > 1\ and\ x < 2)[/tex]
[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:
[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]
Since it is a probability with replacement, we have:
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
For x > 1, we have:
[tex]x > 1 = \{2,3,4,5\}\\[/tex]
[tex]n(x > 1) = 4[/tex]
For x < 2, we have:
[tex]x < 2 = \{1\}[/tex]
[tex]n(x < 2) = 1[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
becomes
[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Answer:
Well..They gave you the hint all you have to do is apply the formula
hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]
So lets do this
axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]
Hope that answers your question
Don't hesitate to comment if you are confused about something
Step-by-step explanation:
Find the equation of the axis of symmetry of the following parabola algebraically.
y=2x^2+16.
Answer:
x = 0
axis of symmbery = -b/2a or x vertex on quadratic equation
0/4=0
x=0

According to the stem-and-leaf plot above, how many drivers travel below 80 miles hour per hour? A. 2 B. 6 C. 14 D. 5
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot
Required
Drivers that travel below 80 mph
A stem and leaf plot has the following syntax: Stem | Leaves
Take for instance:
7 | 2 3 4 7
The above represents 72, 73, 74 and 77
Using the above illustration, the attached leaf plot can be interpreted as:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
80 81... and so on
The drivers that drive below 80 mph are:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
And the frequency is: 12
Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)
