Answer:
123
Step-by-step explanation:
the two triangles are equiangular.
VZ/ZY = VW/WX
13.5/27.5 = VW/36
VW= 16.5*36/27.5 = 21.6
WZ/XY= 3/5
WZ:XY= 3:5
Pythagoras THEROM
44^2 + XY^2= 57.6^2
XY= 37.17
THE PREMETER = 22.3+37.17+36+27.5=123

-2 1/3 ÷ 4 2/3
Please help, I will grant the 1st person to answer correctly brainliest.
Answers
Answer: -1/2
Step-by-step explanation:
1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.
2. We can do the same with 4 2/3, which would be 14/3.
3. Now, we are left with -7/3 divided by 14/3.
4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.
5. -7/3 x 3/14 = -21/42
6. We can simplify this to -1/2.

Answer:
[tex]\dfrac{3}{2}\; \sf cm/s[/tex]
Step-by-step explanation:
To determine the unit rate corresponding to the proportional relationship shown in the given graph, we need to calculate the slope of the line.
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) can be found using the slope formula:
[tex]\boxed{\textsf{slope} =\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
Substituting the defined points (0, 0) and (6, 9) into the formula, we can calculate the slope:
[tex]\textsf{slope} =\dfrac{9-0}{6-0}=\dfrac{9}{6}=\dfrac{3}{2}[/tex]
Therefore, the slope of the line is 3/2.
The slope represents the rate of change between the two variables.
Therefore, the unit rate corresponding to this proportional relationship is 3/2 cm/s. This means that for every increase of 2 seconds, there is a corresponding increase of 3 cm.

please help with surface area of cylinder
Answers
Answer:
Step-by-step explanation:
The surface area of a cylinder can be calculated using the formula:
SA = 2πr^2 + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14.
Looking at the given diagram, we can see that the height of the cylinder is 10 cm and the radius of the base is 6 cm.
So, substituting these values into the formula:
SA = 2π(6)^2 + 2π(6)(10)
SA = 2π(36) + 2π(60)
SA = 72π + 120π
SA = 192π
Using a calculator, we can approximate this value to:
SA ≈ 602.88 cm^2
Therefore, the surface area of the cylinder is approximately 602.88 cm^2.

Question: The drying times in hours for a new paint are as follows:1.5,0.8,2.4,0.5,1.3,2.7,3.6,3.2,2.0,1.9 What is the median drying time
A. 1.99
B.1.95
C.1.9
D.1.5
E. NONE OF THE ABOVE
Answers
Answer:
First, we need to arrange the numbers in order:
0.5, 0.8, 1.3, 1.5, 1.9, 2.0, 2.4, 2.7, 3.2, 3.6
There are 10 numbers in the list, so the median is the middle value. In this case, the middle values are 1.9 and 2.0. To find the median, we take the average of these two numbers:
(1.9 + 2.0) / 2 = 1.95
Therefore, the median drying time is 1.95 hours, option B.

(d) 270 = 38(h -1) +42; h = 7
(e) Brian charges $270 for working 7 hours
Step-by-step explanation:
Given a table of costs and hours for hiring DJs Celinda and Brian, you want to know their hourly costs, equations for their costs, cost for 5 hours, and hours for a cost of $270.
(a) Hourly costThe cost of an additional hour can be found by subtracting the cost for 1 hour from the cost for 2 hours:
Celinda: $88 -52 = $36 . . . . . cost increase per hour
Brian: $80 -42 = $38 . . . . . . . cost increase per hour
(b) EquationsWe can use the "point-slope form" equation of a line to write the equations for the costs.
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Rearranging, this is ...
y = m(x -h) +k
Here, the slope is the cost per hour. A suitable point is the first one in the table. The variables 'c' and 'h' are defined for us.
Celinda: c = 36(h -1) +52
Brian: c = 38(h -1) +42
(c) 5 hoursUsing h=5 in each of these equations, we have ...
Celinda: c = 36(5 -1) +52 = 196 . . . . cost for 5 hours
Brian: c = 38(5 -1) +42 = 194 . . . . cost for 5 hours
(d) $270 to Brian
Using the equation for Brian's cost, we simply need to set c=270 to have the equation we need:
270 = 38(h -1) +42 . . . . equation to find hours
The solution to that equation is ...
270 -42 = 38(h -1) . . . . . subtract 42
228/38 = h -1 . . . . . . . . . divide by 38
6 +1 = h = 7 . . . . . . . . . . . add 1. This is the solution.
It would cost $270 to hire Brian for 7 hours.
(e) DescriptionThe solution to the equation for c=270 is h=7. Since h represents the number of hours the DJ is working, this solution tells us Brian will charge $270 for working 7 hours.
__
Additional comment
The two equations can be simplified by eliminating parentheses and combining like terms:
Celinda: c = 36h +16
Brian: c = 38h +4
Parts (d) and (e) work together. The "solution" h=7 doesn't mean anything except in the context of the question it is answering. The question is "how many hours for a charge of $270." The value h=7 means the answer is Brian charges $270 for 7 hours' work.
The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.
a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent
Which of the following conclusions can we draw from the circle graph?
Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.
Answers
Answer:
Step-by-step explanation:
(i) Number of people who are into classical music =10%
10% of pie chart =20 people.
1% ⇒ 10/20 ×100
and 100% ⇒ 10/20 ×100 × 100/ 100
⇒200 people.
(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.
(iii)
Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100
umber of CD's of semi classical music = 100/20 × 1000(20%) =200
just like that 30% is 300, 40% is 400.

Mars has a polar diameter of 6752 kilometers, and the Mars Reconnaissance Orbiter comes as close to the planet as 255 kilometers. How far does MRO travel in one orbit?
Answers
Answer:
MRO’s orbit is near enough to circular
that the formulas for circles can be used.ep-by-step explanation:
The MRO completes one orbit around Mars in about 2.3 hours, and travels a distance of 40,727 km in that time.
What is MRO?The Mars Reconnaissance Orbiter (MRO) is an orbiting spacecraft that was launched in 2005 by NASA. The objective of MRO is to study the climate, geology, and geography of Mars. MRO is currently in a nearly circular polar orbit around Mars, which allows it to observe the entire planet in high resolution. MRO has an orbital altitude of 255 km, and its orbital period is about 2.3 hours.
The circumference is 2πr, where r is the radius of the orbit. The radius of the orbit of MRO is the difference between the polar diameter of Mars and the closest approach of MRO to the planet, which is 6752 km - 255 km = 6507 km.
Thus, the circumference of the orbit of MRO is 2πr = 2π x 6507 km = 40,727 km. Therefore, the MRO travels 40,727 km in one orbit.
