r /2 − 2 r⋅ 2/ 2+ 6 − 3
r/ 2 + − 2r ⋅ 2/ 2 + 6 − 3
r − 2 r ⋅ 2 /2 + 6 ⋅ 2/ 2 + − 3 ⋅ 2/ 2
r − 2 r ⋅2 + 6⋅ 2 − 3 ⋅ 2 /2

Orginally each face of the pyramid shown to the. Right was a triangke withg the dimensions 109m and 190m . How far was a corner of the base from the pyramis top
Answer:
219.05 m²
Step-by-step explanation:
Dimension of right angle triangle : 109 m and 190 m
The right angle triangle has a height of 190 m and base length of 109 m
A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :
Let :
hypotenus = c ; base = b ; height = a
Hypotenus² = opposite² + adjacent²
c² = a² + b²
c² = 190² + 109²
c² = 36100 + 11881
c² = 47981
c = sqrt(47981)
c = 219.04565
A corner of the base from the pyramid's top is 219.05 m²
Which expressions have a value that is 8 times as much as the sum of 10 and 9? Select the correct answers.
0- 8 x (10 + 9)
1 - 8 x 10 + 9
2- 10 + 9 x 8
3- (10 + 9) x 8
4- (10 x 8) + 9
Answer:
3
Step-by-step explanation:
(10+9) = 19
19×8 =152
when you divide 152by8 you still get 19 which is the sum of 10+9

By observing the frequency polygon,
the number of 15 year old students who took part in the survey are 300.
What is frequency polygon?A frequency polygon is almost identical to a histogram, which is used to compare sets of data or to display a cumulative frequency distribution. It uses a line graph to represent quantitative data.
To calculate the number of students, we add all frequency points corresponding to the time intervals.

3. How would you explain to someone who has not yet studied trigonometry the
difference between an identity and an equation?
Answer:
Solving an equation means finding the value or values for which the two expressions are equal. ... An identity is an equation which is always true, no matter what values are substituted.
A trig identity is an equation that is true for all values of x;
For example:
sin²x + cos²x will always equal 1 no matter what the value of x.
There are some equations considered to be identities that are in fact not true all the time.
tan(2x) = 2tanx/(1 - tan²x) is not true when x = π/2 (right side is undefined).
A conditional equation is one that is true for a subset of the real numbers, i.e. for certain values of x, but not all.
For example:
sin²x - 1 = 0 is only true for some values of x.
sin²x = 1
sinx = ±√(1) = ±1
sinx = 1 or sinx = -1
x = sin-11 or x = sin-1(-1)
x = π/2 + 2kπ, k any integer or x = 3π/2 + 2kπ, k any integer (this can be condensed, but left this way for emphasis).

What is the volume of the rectangular prism?
9514 1404 393
Answer:
17 7/9 yd³
Step-by-step explanation:
The volume is the product of the dimensions.
V = LWH
V = (3 1/3 yd)(2 2/3 yd)(2 yd) = (10/3)(8/3)(2) yd³ = 160/9 yd³ = 17 7/9 yd³
__
Additional comment
You can guess the correct answer with a couple of estimates.
volume is greater than (3)(2)(2) = 12 . . . . rounding down to integer
volume is less than (3 1/3)(3)(2) = 20 . . . . rounding 2 2/3 up to 3
Based on the way these numbers are rounded, the volume is closer to 20 than to 12. This strongly suggests that 17 7/9 is the correct answer.

Given:
Endpoints of a line segment EF are E(-3,8) and F(7,-7).
Point P divides the segment EF such that EP:PF = 2:3.
To find:
The coordinates of the point P.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of the points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that EP:PF = 2:3. It means the point P divides the segment EF in 2:3.
Using section formula, we get
[tex]P=\left(\dfrac{2(7)+3(-3)}{2+3},\dfrac{2(-7)+3(8)}{2+3}\right)[/tex]
[tex]P=\left(\dfrac{14-9}{5},\dfrac{-14+24}{5}\right)[/tex]
[tex]P=\left(\dfrac{5}{5},\dfrac{10}{5}\right)[/tex]
[tex]P=\left(1,2\right)[/tex]
Therefore, the coordinates of the point P are (1,2).

Compare and contrast pyramids and cones.
Be sure to use mathematical terms to describe parts of the solids.
a. In what ways are they alike?
b. In what ways are they different?
Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids.
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
Step-by-step explanation:

The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.
Pyramids and cones are alike in the following ways:
Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.
The formula for the area of a right angle triangle is:
A = hb/2
The area of a cone is given as:
A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]

Answer:
2.7 kb
Step-by-step explanation:
Total kb = 7.48
Total apps = 2
one app = 4.78
another app = x

Answer: I think 8?
Step-by-step explanation:
You might be adding the 6 so therefore maybe you do 6+2= 8 if the median was eqaul to 6.
If this isnt right, I'm sorry!
Answer: 1
The set is:
6 1 5 4 8 7 2 1 2 2
First: We get the median of the original set. To do this we change it from highest to lowest.
1 1 2 2 2 4 5 6 7 8
Then we take the middle number of this set which is the median
2 and 4 are the middle so the median is 3
The median of set 1 is 3
Second: We get the median of the set but with another 6 added
1 1 2 2 2 4 5 6 6 7 8
Take the middle number of this set which is the median
4
The median of set 2 is 4
From this we know the median increases by 1 if the number 6 is added!
