What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
Answer:
A
Step-by-step explanation:
The density of the pyramid is approximately 0.57 grams per cubic centimeter.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
To find the density of the pyramid, we need to know its volume as well as its mass.
The volume of a pyramid is given by:
V = (1/3) × base area × height
The base of the pyramid is a rectangle with dimensions 5 cm by 7 cm, so its area is:
A = 5 cm × 7 cm
= 35 cm²
Using the formula for the volume of a pyramid, we have:
V = (1/3) × A× h
V = (1/3) × 35 cm² × 9 cm
V = 105 cm³
Now we can calculate the density:
density = mass / volume
Since the mass of the pyramid is given as 60 grams, we have:
density = 60 g / 105 cm³
To get the density in units of grams per cubic centimeter, we need to convert the units of mass and volume to grams and cubic centimeters, respectively:
density = (60 g / 1000) / (105 cm³ / 1000)
density = 0.57 g/cm³
Therefore, the density of the pyramid is approximately 0.57 grams per cubic centimeter.

How do you solve b^2=-3b
Answer:
b=0,-3
Step-by-step explanation:
b^2+3b=0
b(b+3)=0
b=0
b+3=0
b=-3
Answer:
b = 0 OR b = -3
Step-by-step explanation:
To start off with, we know that this must be a quadratic equation because there's a "^2".
Firstly, we have to bring everything over to one side of the equation. This means we have to add 3b to both sides, as we want the right-hand side to be 0.
b^2 = -3b
+3b +3b
b^2 + 3b = 0
Secondly, we have to factorise. We need to see what number goes into both "b^2" AND "3b".
That is "b".
b^2 + 3b = 0
factor out b
b(b + 3) = 0
Thirdly, we have to use the Null Factor Law to find out what b equals. The Null Factor Law states that if an equation equals 0, then one of the terms must either be 0, or the negative of the other number.
Hence, there are two answers.
b = 0
OR
b = -3
Line segment ĀB has endpoints of A(-3,7) ans B(3,15). Identify the slope of a line perpendicular to ĀB
Answer:
m = -3/4
Step-by-step explanation:
Let's look at how much x and y change as we move from A to B:
x increases by 6, from -3 to 3, and y increases by 8, from 7 to 15. Thus, the slope, m, is rise / run, or (change in y): m = 8/6 = 4/3.
Now any line perpendicular to AB has a slope which is the negative reciprocal of this 4/3: m = -3/4

Which is the expected value of the random variable with given probability distribution ?
Answer:
Step-by-step explanation:
Let X be the RV we are talking about.
Expected value has different aliases, such as weighted average, mean, expectation, first moment and so on.
Okay, how do we calculate the average first, just sum all the values and divide by number of values. It comes from the basic assumption, which is choosing one of them is equally likely. What I mean by that is quite simple, above process what I talked about is just sum of the numbers times their probabilities. e.g. (a+b+c+d)/4 = a/4 + b/4 + c/4 + d/4. In the example, we assumed that probability of choosing any a, b, c and d is equally likely.
Then, why I use the term weighted average is the generalized situation of average, which is some of the numbers are repetitive. For instance, X can take the values a, b, c and d; however, X can take the value a 3 times more than d, X can take the value b 2 times more than d and c and d occurs with the same frequency at X, Therefore, if we take a sample, it is likely to be a, b, a, c, d, a, b or the permutation of this sample. Therefore the weighted average is 3 * a / 7 + 2 * b / 7 + c / 7 + d /7 or using normal average theorem (a + a + a + b + b + c +d) / 7. First, both of them are equal. Find the distribution and multiply the values with the probabilities of the distribution and sum them up or just add them and divide by number of sample. Second, if you check that, a has more weight, which means a can determine the direction of the average more. That is the logic behind the expected value.
Now, if X is a discrete RV (like in the above example), we know what we are going to do. What if X is a continuous RV ? X could take infinite values therefore if you divide a number with an infinite value, the probability of an individual value X could take is going to be 0. Therefore, we cannot calculate the expected value of chosen values individually; however, we can calculate the expected value of an interval by approximating with Riemann Sum or with a better choice, using integrals. Because, technically using Riemann Sum and quantizing the values and approximating the area of the curve is the same as we did above.
In conclusion, basically if X is a discrete RV and the values X could take is countably infinite,
If X is a discrete RV and the values X could take is finite,
if X is a continuous RV,

Hillary is making a blanket for her mom. Three fourths of the blanket is green and the rest is yellow. Two thirds of the yellow part has her name on it. What fraction of the blanket will, have her name on it?
Answer:
1/6
Step-by-step explanation:
Hillary is making a blanket for her mom.
Let the total blanket = 1
Three-fourths of the blanket is green and the rest is yellow.
The fraction for the rest(yellow portion) = 1 - 3/4
The Lowest Common Denominator is 4
Hence,
4 - 3 /4 = 1/4
Two-thirds of the yellow part has her name on it.
The fraction of the blanket that will have her name on it is calculated as
2/3 of 1 /4
= 2/3 × 1/4
= 1/6
459,450,441, find the 37th term
Answer:
135
Step-by-step explanation:
So, our first term is 459.
Lets find what our change in terms is. To do this, lets subtract the frist term by the second:
459-450
This will get you 9.
Now that we know our change per term, lets find our 37th term.
All we need to do, is take our first term, and subtract it by our change in terms times the amount of terms.(Note that we already know are 1st term, so we are multiplying the change in terms by 36, not 37. )
So this is what we can use to solve for this:
459-(9x37)
This equals
135.
Hope this helps!
Step-by-step explanation:
first term = a = 459
common difference = d = 450 - 459 = -9
nth term = an
n = -9
an = a + (n-1)d
= 459 +(37-1)-9
= 459 + (36)-9
= 459 -324
= 135
37 th term = 135

Right triangles 1-2 and 3 are given with all their angle measures and approximate side lengths.
Use one of the triangles to approximate the ratio WY/WX
A. 0.34
B. 0.94
C. 1.06
D. 2.76
Answer:
0.34
Step-by-step explanation:
Considering the right-angled triangle XYW, an approximate ratio WY/WX is equal to 0.34. The correct option is A.
What is a right-angled triangle?A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangle triangle. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Considering the right-angled triangle XYW, we would apply the law of cosine to approximate the ratio WY/WX. Mathematically, the law of cosine is given by:
cos(θ) = Adj/Hyp
Where:
Adj is the adjacent side of a right-angled triangle.
Hyp is the hypotenuse of a right-angled triangle.
θ is the angle.
Substituting the given parameters into the formula, we have;
cos(θ) = WY/WX
cos(70) = 3.4/10
0.34 = 0.34.
Therefore, the correct option is A.

hey so the angles in a triangle add up to 180°.
take your given angles away from that to find your 3rd angle
180-68-85-27°
angles on a straight line also add up to 180°
so you need to take 27 from 180 to find your answer

l= 64/4
l=16
Answer:
Step-by-step explanation:
since it's a square we know the 4 sides are the same length.
64 / 4 = 16
so each side is 16.... now use pythagoras to solve for GE since we know the two legs of the triangle .. both 16
16^2 + 16^2 = GE^2
