Which list shows the numbers below in order from least to greatest?

Answer: A and D

Step-by-step explanation:

Answer:

diameter = 36 in.

Step-by-step explanation:

V = 4π r^3/3

24416.64 = (4(3.14) r^3)/3

73249.92 = 12.56 r^3

r^3 = 5832

r = cube root of 5832 = 18

diameter = 36 in.

Answer:

7 5/9

Step-by-step explanation:

340/45 = 7 5/9

Answer:

7.6 pages

Step-by-step explanation:

Okie, so this is a standard unit rate problem, so what you're going to do is divide the number of whatever, in this case, pages, by the time, so:

340 ÷ 45 = 7.6 (rounded)

So you read 7.5 pages per minute

(which is pretty impressive if it's a chapter book)

hope this helps:)

Answer:

m a t h

Step-by-step explanation:

i am in middle school so i dont know

Answer:

see below

Step-by-step explanation:

Our equation is y = 1/2x - 1. This mirrors our standard linear parent function of y = mx + b.

m is the slope and b is the y-intercept.

From this, we can see that

m = 1/2

and

b = -1.

The first point given is the y-intercept because with y-intercepts, we know the coordinates right away. A y-intercept's coordinates will always have an x-value of 0. This allows it to lie on the y-axis, hence the name. Our y-value of the coordinates is given with the b value of the equation. Therefore, by simply looking at the end of the equation, we know our first point.

Hope this helps!

Answer: I would say 6 its a function and 7 its not because in number seven the x value repeats so it can't be a function and number 6 the x-value its not the same

Step-by-step explanation: When the x-value repeats its not a function if the y-value repeats it doesn't matter

Answer:

(0, -4)

Step-by-step explanation:

To find the y-intercept, set x equal to zero:

y = -3(0) - 4, or y = -4, or (0, -4)

Answer: (0,4)

Step-by-step explanation:

Answer:

A. DEF=EDF

Step-by-step explanation:

Answer:

(x+1)² = 7

Step-by-step explanation:

Given the expression

-2x = x² - 6

Rewrite

x² - 6 + 2x = 0

x²+2x-6 = 0

Add 6 to both sides

x²+2x-6+6 = 0+6

x²+2x = 6

Add square of half of coefficient of x to both sides

Coefficient of x = 2

Half of Coefficient of x = 2/2 = 1

Square of half of Coefficient of x = 1² = 1

Add 1 to both sides

x²+2x + 1= 6 + 1

Factorize the LHS

x²+x+x + 1 = 7

x(x+1)+1(x+1) = 7

(x+1)(x+1) = 7

(x+1)² = 7

hence the equation rewritten by completing the square method is

(x+1)² = 7

Answer:

10 and 2

Step-by-step explanation:

a + b = 12

a - b = 8

let 'a' = 8 + b

substitute:

8 + b + b = 12

2b + 8 = 12

2b = 4

b = 2

a must be 10 then

Answer:

0.81 hour

Step-by-step explanation:

Given data

Distance=  544.32 miles

Speed=  672 miles per hour.

We know that

Speed= distance/time

Substitute

672=  544.32/time

cross multiply

time*672= 544.32

time= 544.32/672

time= 0.81 hour

Answer:

See the solutions below

Step-by-step explanation:

Initial Salary= $925

Final salary=  $1036

% increase= Change/initial *100

substitute

% increase= 1036-925/925 *100

% increase=111/925 *100

% increase=0.12 *100

% increase=12%

2. Let us find 16% of $925

=16/100*925

=0.16*925

=$148

Hence the salary would have been

=148+925

=$1073

Answer:

[tex] {3}^{2} x - 9 = 0 \\ 9x = 9 \\ x = 1[/tex]

Answer:

[i] 12x + 5 = 1/2(83 +95)

12x + 5 = 89

12x = 84

x = 7.

[ii] 9x + 7 = 1/2(198 + 7x - 8)

18x + 14 = 198 + 7x - 8

11x = 176

x = 16.

[iii] 15x - 8 = 1/2(16x +1 + 5x + 19)

30x16 21x + 20

9x = 36

x = 4.

[iv] 20x - 4 = 360 - 2 × 72

20x = 220

x=220/20=11°

[v] 13x - 1 = 2(6x + 11)

13x - 1 = 12x + 22

x = 23.

[vi] 46 = 1/2(21x-5-x-23)

20x2892

20x = 120

x = 6.

[vii] 6x - 21 = 1/2(13x - 3-3x - 11)

12x - 4210x - 14

2x = 28

x = 14.

[viii] 2x + 1 = 1/2(9x − 14 − 4x + 7)

4x + 2 = 5x - 7

x = 9.

[ix] 9x - 4 = 180 - 76

9x - 4 = 104

9x = 108

x = 12.

Answer:

Step-by-step explanation:

9.2  to  9.3    the top right one

The lowest common denominator is 120.

Convert 3/4: 90/120

Convert 4/5: 96/120

Convert 5/6: 100/120

Answer:

a - yes

b - no

Step-by-step explanation:

triangle inequality theorem - the sum of any 2 sides of a triangle must be greater than the measure of the third side

For a

5 + 4 must be greater than 7 for the set to be measures of the sides in a triangle

5 + 4 = 9

9 is greater than 7 therefore 4,5, and 7 can be measures of the sides in a triangle

For b

3 + 2 must be greater than 6 in order for the set to be measures of the sides in a triangle

3 + 2 = 5

5 is less than 6 therefore 2,3 and 6 can not be measures of the sides in a triangle

as fraction 21/16

decimal form- 1.3125

Mixed number- 1  5/16

Actually Welcome to the concept of areas,

we know that, area of rectangle = length * width,

here, length = x-2 and width = x-1

hence, area = (x-2) (x-1)

==> area = x^2 -x -2x +2

==> Area = x^2 - 3x + 2

hence the Option D.) is correct

Answer:

A the first one.

Step-by-step explanation:

Answer:

Step-by-step explanation:

This is a parallelogram. It is a quadrilateral with two pairs of parallel sides. Here, the opposite angles are alternate, that is, they have togheter 180°.

Rhombus

This is a rhombus. It is a quadrilateral whose four sides all have the same length. Here, the diagonals of a rhombus intersect at equal angles.

A rhombus has opposite angles equal and the figure formed by joining the midpoints of the sides of a rhombus is a rectangle, and vice versa. It has an inscribed circle.

Good luck:)

Answer:

Step-by-step explanation:

Cylinder 1

Cylinder 2

Surface area of cylinders:

The difference is:

A cylinder has a radius of 4 inches and a height of 5 inches. If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ? Answer in terms of Pi.

A cylinder has a radius of 4 inches and a height of 5 inches.

If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ?

[tex] \bullet [/tex] Radius [tex] (r_1) [/tex] is 4 inches

[tex] \bullet [/tex] Height is 5 inches

[tex] \bullet [/tex] Radius [tex] (r_2) [/tex] is 3 × 4 = 12 inches [as in the question it is given that the radius of the cylinder is tripled]

[tex] \bullet [/tex] Height is 5 inches

Now,

Surface area [tex] (s_1) [/tex] of 1st cylinder

is 2πr(r + h) = 2π × 4(4 + 5)

= 8π(9)

Surface area [tex] (s_2) [/tex] of 2nd cylinder

is 2πr(r + h) = 2π × 12(12 + 5)

= 24π(17)

[tex] \therefore [/tex] The difference in the surface areas of the two cylinders is = [tex] (s_2 \: - \: s_1) [/tex] = (408π - 72π) = 336π sq inches

Answer: No, 3.8 is not a solution.

Step-by-step explanation:

Set -5x+1 equal to 3x-2

-5x+1=3x-2 subtract 3x making it -8x+1=-2 subtract one from both sides and get -8x=-3 divide by -8 and get -3/-8 which equals in decimal form 0.375

Check it

plug in 0.375 for X

-5(0.375)+1= -0.875

3(0.375)-2 = -0.875

It checks out ^_^

Answer: 10 visit

Step-by-step explanation:

Given

45 Points earned by signing up

11.5 points earned for each visit to the theatre

160 points are needed for a movie ticket

Suppose, after x visit he gets enough points to buy a movie ticket

[tex]\therefore 160=45+11.5x\\\Rightarrow 115=11.5x\\\Rightarrow x=10[/tex]

So, after 10th visit, he earns a movie ticket
