Dimensions of rectangular prism 5.2 in by 4.5 in by 6.0 in and weighs 1587 grams. What is the density?
Answer:
11.30 g/in^3
Step-by-step explanation:
Given data
Dimensions of a rectangular prism
5.2 in by 4.5 in by 6.0 in
Hence the volume is given as
Volume= 5.2*4.5*6.0
Volume= 140.4in^3
Weight= 1587 grams
We know that density is
Density= mass/volume
Density= 1587 / 140.4
Density= 11.30 g/in^3

Area is a measure of how much space there is inside a shape. Calculating the area of a shape or surface can be useful in everyday life – for example you may need to know how much paint to buy to cover a wall or how much grass seed you need to sow a lawn.
This page covers the essentials you need to know in order to understand and calculate the areas of common shapes including squares and rectangles, triangles and circles.

For purposes of making on-campus housing assignments, a college classifies its students as Priority A (seniors), Priority B (juniors), and Priority C (freshmen and sophomores). Of the students who choose to live on campus, 22% are seniors, 29% are juniors, and the rest are underclassmen. The most desirable dorm is the newly constructed Gold dorm, and 71% of the seniors elect to live there. 19% of the juniors also live there, along with only 5% of the freshmen and sophomores. What is the probability that a randomly selected resident of the Gold dorm is a senior? Show as much work as possible.
Answer:
The probability that a randomly selected resident of the Gold dorm is a senior is 0.1562
Step-by-step explanation:
The given percentage of each class of student is presented as follows;
Priority A (seniors) = 22%, ∴ P(s) = 0.22
Priority B (juniors) = 29%, ∴ P(j) = 0.29
Priority C (freshmen and sophomores) = (100 - 22 - 29)% = 49%, ∴ P(fs) = 0.49
The percentage of the seniors that elect to live at the Gold dorm, = 71%, ∴ P(sG) = 0.71
The percentage of the juniors that live at the Gold dorm = 19%, ∴ P(jG) = 0.19
The percentage of the freshmen and sophomores that live in the Gold dorm = 5%, ∴ P(fsG) = 0.05
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = P(s) × P(sG)
∴ P(s∩sG) = 0.22 × 0.71 = 0.1562
Therefore;
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = 0.1562.

Step-by-step explanation:
The length of a planet's orbit around a star is approximately 22,200,000 km.
It takes the planet about 1230 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
Speed = 7520 km/h
Step-by-step explanation:
Given the following data;
Distance = 22,200,000 km.
Time = 1230 Earth days
To find the average speed of the planet;
First of all, we would have to convert the time in Earth days to hours;
1 Earth day = 24 hours
1230 Earth day = x
Cross-multiplying, we have;
x = 1230 * 24
x = 29520 hours
Therefore, time = 29520 hours
Substituting into the formula, we have;
Speed = 22200000/29520
Speed = 7520.325 km/h
To 3 significant figures;
Speed = 7520 km/h

Solve for the surface area of the figure below..
Answer and Step-by-step explanation:
To find the surface area, we have to find the area of all the faces of the shape, then add them together. We also only use the exposed faces, or the faces on the outside, not the inside.
Lets start with the rectangular prismed shape.
We have two faces with sides of 4 and 5, two faces with sides 16 and 4, and 1 side with 16 and 5.
Rectangles:
4 × 5 = 20
4 × 5 = 20
4 × 16 = 64
4 × 16 = 64
5 × 16 = 80
Now, let's do the triangles up top. There will essentially be 4 triangles, because we split them in half to find the area.
They have side lengths of 6 and 8.
Triangles:
6 × 8 = 48
6 × 8 = 48
6 × 8 = 48
6 × 8 = 48
Now, we have to the two rectangles up top.
They have side lengths of 10 and 4.
Top Rectangles:
10 × 4 = 40
10 × 4 = 40
Now, we add them all together.
20 + 20 + 64 + 64 + 80 + 48 + 48 + 48 + 48 + 40 + 40 =
40 + 208 + 192 + 80 =
520.
The Surface Area of the figure is 520 [tex]m^2[/tex]

What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Number of candles =(total volumes used by the company)/(volume of one candle)
Volume of one candle =5cm x 2cm x 12cm=120cm^3
Number of candles =5040/120
N = 42 candles
Therefore, the number of candles will be 42.

Find the value represented by a z-score of 2.403, given µ=63 and σ=4.25. Round your answer to one decimal place.
Answer:
16.5
Step-by-step explanation:
Find the value represented by a z-score of 2.403, given µ=63 and σ=4.25. Round your answer to one decimal place.
The z score formula =
z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 63
σ is the population standard deviation = 4.25
z = 2.403
Hence,
2.403 = (x - 63)/4.25
Cross Multiply
2.403 × 4.25 = x - 6.3
10.21275 = x - 6.3
Collect like terms
10.21275 + 6.3 = x
x = 16.51275
Approximately to 1 decimal place the value = 16.5

#CMIIWfind the measure of each interior angle of a regular polygon with the following number of sides 12
Answer:
each interior angle = 150°
Step-by-step explanation:
(N x 180°) - 360° = the sum of interior angles
where N = the number of sides
(12 x 180°) - 360° = 1800°
Since it is a regular polygon, all 12 angles are equal:
1800°/12 = 150°
