What is the smallest number you can form with the given cards? ... Alex, Hans and Stan saved money to buy a tent for a camping trip. Stan ... Alex saved 40 % of what was left of the price.

Answer:

b^(-6)

Step-by-step explanation:

The numerator of this fraction is b^(-11).  The -11 is the sum of -4 and -7.  

The denominator is b^(-5).

Recall that b^a / b^c = b^(a - c).  Thus, b^(-11) / b^(-5) = b^(-6)

Answer:

B ; C; D

Step-by-step explanation:

The slope measures the rate of change in the dependent variable per unit change in the independent variable :

From the options :

Doing 4 pages of homework in 20 minutes :

The number of pages done per minute = slope

Slope = 20 / 4 = 5

To cycle 32 miles in 4 hours:.

Number of miles to cycle per hour to achieve the feat :

Slope = 32 /4 = 8

Buying 10 shirts for $80:

Cost per shirt = slope

Slope = $80 / 10

Slope = 8

Reading 72 pages in 9 hours

Number of pages read per hour :

72 / 9 = 8 pages

Answer:

8

Step-by-step explanation:

[tex]\frac{65+(\frac{1}{5} *5)+6}{9} \\\\\frac{65+1+6}{9} \\\\\frac{72}{9} \\\\8[/tex]

Answer:

55% of the total books are non-fiction.

Step-by-step explanation:

There are a total of 80 books, and there are 44 non-fiction books among them.

Divide 44 by 80, then multiply by 100 to get the percentage.

(44/80) × 100 = 55%

Answer:

False.

A symmetrical data plot would look the same on each side. For example, it would look like this:

Answer:

408 Cars

Step-by-step explanation:

Dividing 12 Hours by 1.5 hour

= 12/1.5 = 8

Now Multiplying 8 by 51

=51 x 8

= 408 cars  

Answer:

8) 144pi

9) 196pi

11) 18pi

12) 298.67pi

Step-by-step explanation:

The volume of a cylinder is [tex]V = \pi r^{2} h[/tex], where r represents the radius of the base and h represents the height.

For the first cylinder, the radius of the base is 4 and the height is 9.

[tex]V = \pi (4)^{2} (9)\\V = \pi(16)(9)\\V = 144\pi[/tex]

For the second cylinder, the diameter is 6 and the height is 2. Since the radius is half the diameter, the radius is 3.

[tex]V = \pi (3)^{2} (2)\\V = \pi(9)(2)\\V = 18\pi[/tex]

The volume of a sphere is [tex]V = 4\pi r^{2}[/tex], where r is the radius of the sphere.

The diameter is 14, meaning the radius must be 7.

[tex]V = 4\pi (7)^{2} \\V = 4\pi (49)\\V = 196\pi[/tex]

The volume of a cone is [tex]V = \pi r^{2} (h/3)[/tex], where r is the radius and h is the height.

The radius is 8, and the height is 14.

[tex]V = \pi (8)^{2} (14/3)\\V = \pi (64) (14/3)\\V = \frac{896}{3} \pi\\V = 298.67\pi[/tex]

Answer:1231.5

Step-by-step explanation:

volume of a cylinder = pie x r^2 x h

pie x 14 x 8 = 1231.5

Answer:

C: 31 m/s

Step-by-step explanation:

It falls from a dam.

Thus;

Initial velocity; u = 0 m/s

Height; h = 49 m

Acceleration due to gravity is 9.8 m/s²

To solve for the final velocity this, we will use Newton's third equation of motion;

v² = u² + 2gh

v² = 0² + 2(9.8 × 49)

v = √960.5

v ≈ 31 m/s

Answer:

Step-by-step explanation:

(6 * 4) + 2(10 * 5) + (10 * 6)

Multiply 6 by 4 to get 24.

24 + 2(10 * 5) + (10 * 6)

Multiply 10 by 5 to get 50, then multiply by 2 to get 100.

24 + 2(50) + (10 * 6)

24 + 100 + (10 * 6)

Multiply 10 by 6 to get 60.

24 + 100 + 60

Add 24 to 100 to get 124.

124 + 60

Add 124 to 60 to get 184.

184 cm²

The surface area of the prism is 184 cm².

Answer:

m∠1= 38°  

Step-by-step explanation:

180-145= 35

107+35= 142

angles in a triangle add up to 180

if the two known angle add up to 142

just do the easy math

180-142

= 38

m∠1= 38°

Answer:

9x10^15

Step-by-step explanation:

9,460,528,400,000,000

If you count the numbers up until 9 you get 15. So the easy hack is to just count the numbers up until the VERY first then whichever answer had that number is the right one.

Answer:

x = 10

Step-by-step explanation:

OA = OD ( both radii of the circle )

OD = OB + BD = x + 16

OB is at right angles to OB ( line from centre to midpoint of chord is right )

Using Pythagoras' identity in right triangle ABO

OA² = OB² + AB² , that is

(x + 16)² = x² + 24²

x² + 32x + 256 = x² + 576 ( subtract x² from both sides )

32x + 256 = 576 ( subtract 256 from both sides )

32x = 320 ( divide both sides by 32 )

x = 10

Answer:

KJ = 128°

Step-by-step explanation:
