A rectangular pyramid. a parallelogram that is not a rectangle a rectangle a triangle that must have the same dimensions as one of the faces a triangle that does not have the same dimensions as one of the faces
Answers
Answer:
D
Step-by-step explanation:
The figure is a rectangular pyramid. The cross section is perpendicular to the rectangular base and passes through the top vertex of the figure. A triangle that does not have the same dimensions as one of the faces is formed. The sides of the new triangle are the heights of the triangles on the faces of the pyramid, and that is why their dimensions are different.

______________.
How many hours and minutes is that equal to?
_____________.
Answers
Question 1:
48 + 63 + 28 + 44 + 43 = 226 minutes
41 + 40 + 15 + 1 + 39 = 136 seconds
136 seconds = 2 minutes and 16 seconds
The answer is 228 minutes and 16 seconds.
Question 2: 228 minutes = 3 hours and 48 minutes
The answer is 3 hours and 48 minutes, but if you're also counting seconds, add 16 seconds to the end of it.
And the hours and minutes is 3hours and 48 minutes
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Plot and connect the points A (2, -2), B (-4, -4), C (-4, -1), D (-2, 3), E (1, 3), F (2, 5), and find the length of BC.
Answers
Answer:
BC = 3 units
Step-by-step explanation:
Given points:
A = (2, -2)B = (-4, -4)C = (-4, -1)D = (-2, 3)E = (1, 3)F = (2, 5)Plot the points on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).
From visual inspection of the drawn polygon, we can see that the length of BC is 3 units.
It is fairly simple to calculate the length of BC without plotting the points.
As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.
⇒ distance = |-4 - (-1)| = |-3| = 3 units
Distance

Dave owns 15 shares of ABC mining stock. On Monday, the value of each share rose $2, but on Tuesday the value fell $5. What is the change in the value of Dave’s shares?
Answers
Answer:
Let's take each share by itself first.
First, the value of each share rose by 2. So we have +2. Then it fell by 5. So we have 2 - 5 = -3. Each share has a net value of negative 3.
Dave owns 15 shares. So 15 * (-3) = -45.
-$45
Let x = the current value of the stocks
So if each stock increases by 2 dollars - the total value increases by 15 lots of $2
x + (15 x 2) = the new value (we will call this n)
Each stock then decreases in value by $5
So…
n - (5 x 15) = the final value of the stocks (we will call it f)
$2 - $5 = -3$
And -3 x 15 = -45
So Dave has lost $45 in shares

What mixed number represents 30/8
Answers
Answer:
3 6/8
Step-by-step explanation:
30÷8=3 6/8
8×3=24
30-24=6
Answer:
The mixed that represents 30/8 is --> 3 3/4
Step-by-step explanation:
Step 1: Find the whole number
We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.
30/8= 3.75 = 3
Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.
Step 2: Get the new numerator
To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:
30 - (8 x 3) = 6
Step 3: Our mixed fraction
We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:
3 6/8
Step 4: Simplifying our fraction
In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.
We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.
6/2 = 3
8/2 = 4
When we put that together, we can see that our complete answer is:
3 3/4

how can I use A as a different variable.

Answers
You can use A as a different variable by simply assigning a value to it, like any other variable
What is a variable?A variable is a symbol used to denote a mathematical object in mathematics. Any number, vector, matrix, function, function argument, set, or set element can be represented by a variable.
An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable is, in other words, a symbol denoting a number whose value is unknown.
You can use A as a different variable by simply assigning a value to it, like any other variable. For example, you could write "A = -6" to assign the value of negative 6 to A. It's important to remember that A is now a distinct variable from X, Y, and K, and should be treated as such in your code or equations.
