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.

(22 - 4) / 6
The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.
If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?
Answer: 900
Step-by-step explanation:
If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).
To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer

A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.
Step-by-step explanation:
Volume of cylinder = pi r^2 h
Volume of square container = s x s x h
they need to be equal
pi r^2 h = s^2 h
pi (2)^2 * 10 = 4^2 h (diameter = 4 then radius = 2)
40pi / 16 = h = 7.9 in = ~ 8 in to the nearest 1/4 inch

Determine the translation used to create the image.
5 units down
5 units up
1 unit down
1 unit up
The translation used to create the image include the following: A. 5 units down.
What is a translation?In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;
g(x) = f(x + N)
Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.
Based on the information provided, we have:
(x, y) → (x + h, y + k)
(1, -1) → (1, -6).
1 + h = 1
h = 1 - 1
h = 0
-1 + k = -6
k = -6 + 1
k = -5.

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.
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.

Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?
A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.
Answer: B the side length of XZ is 28
Step-by-step explanation:
to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.
for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.
Answer:
B
Step-by-step explanation:
Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.
-2 1/3 ÷ 4 2/3
Please help, I will grant the 1st person to answer correctly brainliest.
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.
