Answer:
40
Step-by-step explanation:
the volume of tetrahedron ABCF =
⅓× ½×5×6×8 = 40
The volume of the given tetrahedron ABCF will be 40 cube units.
What is a tetrahedron?A tetrahedron is a polyhedron having four faces, six edges, and four vertices, all of which are triangles. It is also known as a triangular pyramid with a triangle base.
The ABCDEFGH is a rectangular prism given in the question, which has :
CD = 5, AD = 6, and AE = 8
We have to determine the volume of tetrahedron ABCF.
As per the question, the required solution would be as:
The volume of tetrahedron ABCF = 1/3 × 1/2 × 5 × 6 × 8
Apply the multiplication operation, and we get
The volume of tetrahedron ABCF = 40 cube units
Thus, the volume of the given tetrahedron ABCF will be 40 cube units.

Hey PLZZZZ HELP!
The profits earned in a year by some companies in a city are shown below: Company Profit A $160,000 B $140,000 C $130,000 D $1,120,000 E $150,000 Based on the data, should the mean or the median be used to make an inference about the profits earned by these companies? Mean, because it is in the center of the data Median, because it is in the center of the data Mean, because there are no outliers that affect the mean Median, because there is an outlier that affects the mean
Answer:
mean because there is an outlier
Step-by-step explanation:
since there is an outlier that affected the mean which is company D, it can only be mean because the outlier is too big.

Answer:
a) a + c = 90
d) a + b + c + 30 = 180
e) The angles marked a and b are vertical
f) The angles marked a and c are complementary.
Step-by-step explanation:
A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.

Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.

jenny picked 40 roses and gave away 10. what percent of roses did she give away?
Answer: 25%
Step-by-step explanation:
How do I solve this?
Answer:
We know the width maybe 22ft and at its widest.
IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides
= if regular shape largest line 22 x 7 = 154 ft sq = Area.
Answer:
374
Step-by-step explanation:
First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374
Look at the pic below for the question please help!!

which angles are complementary to each other ? select all that apply
Answer: ∠1 and ∠5
Step-by-step explanation:
You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

-I'll give branliest as a reward-
Answer:
AC=2.868
Step-by-step explanation:
using pythagoras theorem
take 35 degree as reference angle
hypotenuse =5 , opposite =AC , adjacent=BC
using sin rule
sin 35=opposite/hypotenuse
0.5735=AC/5
0.5735*5=AC
2.8675=AC
2.868=AC

helpppp plzzz...plz give steps
Answer:
Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]
Therefore value of r=3 inches

find surface area of the square pyramid!!! pls i need help with explaining!!!!!
Answer:
39 square yards
Step-by-step explanation:
The base is a square, so the area is 3 x 3 = 9.
Each side is a triangle, and the formula for that is (1/2)(base)(height)
The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30
Add the base and sides
30 + 9 = 39
Answer:
39 yards
Step-by-step explanation:
surface area = A + [tex]\frac{1}{2}[/tex] ps
A = area of the base
p = perimeter of the base
s = slant height
the base of the pyramid is a square, all sides and angles are equal
; 3 yards
; area of a square = l x w
; area of the base = 9 yd (A)
perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)
slant height = 5 yd (s)
; sub it into the formula
surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5
surface area = 39 yd
Write an equation that represents the line. Use exact numbers.
y = 6/5x -5
6/5 is your slope. Slope is always rise over run or y over x. -5 is the y- intercept. What is y when x is zero.
