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

Which two statements about the volumes of the prisms are true?
A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet

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.

Answer:
A
Step-by-step explanation:
A: -a/-b=c (negative number divided by negative number is positive number A is correct)
B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)
C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)
D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)

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:

First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374
HELP ME ASAP!!! Tristan is stacking building blocks to make a tower. He takes a break when the tower is 5 2/5 feet tall, which is 1/3 of the height of the tower he wants to build. How tall is the tower when finished? Check all that apply
A. 1/3 x ? = 5 2/5
B. 1/3 ÷ 5 2/5 = ?
C. 5 2/5 x ? = 1/3
D. 5 2/5 x 1/3 = ?
E. 5 2/5 x 3/1 = ?
F. 5 2/5 ÷ 1/3= ?
Honestly, I'm not sure how to answer this, but I think this can help you.
Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.
(I think F is an answer)

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.

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function? Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Answer:
A because (0,-6) is the y-intercept so you start at the point you know. Then because slope is a rise over run fraction the slope can also be written as 2/1 which is rise 2 over 1.
Step-by-step explanation:
w
Answer:
A, cuz (0,-6) is the y-intercept. You start at the point that is familiar to u. Then cuz slope = rise over run, simplify the slope which is 2/1.

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
Example Given
Find a or b
a = 20. b = ? c = 25
Find b or a. c^2 - a^2 = b^2
25^2 - 20^2 = c^2
625 - 400 = 225
Square Root of 225 is 15

1.45 degrees
2.45 dehrees
3.135 degrees
4.135 degrees
5.45 degrees
6.135 deegres
please give brainliest
Answer:
Step-by-step explanation:
for first fox
let it be x
x + 135 degree = 180 degree (being straight line)
x = 180 - 135
x = 45 degree
therefore figure upper box is 45 degree
for box that is just below 135 degree
first fox = box just just below 135 degree
45 degree = box just below 135 degree
for box that is just below 45 degree
box that is just below 45 degree = 135 degreee (being vertically opposite angles)
for the box that lies on the left side of the transversal
let the fourth box that les on the left side be x
135 + x = 180 degree (being co interior angle)
x = 180 - 135
x = 45 degree
for the box that lies on the right side of the transversal .Let it be y
45 + y = 180 degree
y = 180 - 45
x = 135 degree
y = last box that lies on the left side of 45 degreeing vetically opposite angles)y
last box = 135 degree
