Solve the word problem and ratio table

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

Answer: more than 500 shirts will be washed each day

Step-by-step explanation:

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.

Hope this helped :)

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.

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

Answer:

Step-by-step explanation:

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?

we can solve with an equation

80 : 24 = 3000 : x

x = 24 * 3000 : 80

x = 900

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.

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.

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.

The translation used to create the image include the following: A. 5 units down.

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.
