Write a numerical expression that has a value equal to each number from 1 through 30. In each expression, use each of four consecutive digits from 0–9 exactly once.

Answer:

The figure should be 56 units squared.

Step-by-step explanation:

The long side is 14 units long (6+6+2) and the short side is 4 units long, so 14 multiplied by 4 is 56.

Answer:

9 + 2j is the required algebraic equation.

Answer:

9.4 seconds or 1 second

Step-by-step explanation:

From;

h = ut ± 1/2gt^2

h = 12 feet

g = acceleration due to gravity = 10 m/s^2

u = 26 ft/sec

Since it is an upward motion g is negative

12 = 26t - 5t^2

Hence;

5t^2 - 26t + 12 = 0

Solving the quadratic equation

Considering that the time taken to go up is the same time taken to hit the ground again

t = 2(4.7) seconds or t = 2(0.5) seconds

t = 9.4 seconds or 1 second

Answer:

S.A. = 1,017.36

Step-by-step explanation:

S.A. = [tex]\pi r^{2} + \pi rl[/tex]

12 x 12 x 3.14 = 452.16

3.14 x 12 x 15 = 565.2

565.2 + 452.16 = 1,017.36

Answer:

Widgets: 12

Wombats: 15

Step-by-step explanation:

Let x represent widgets

y represent wombats

Set up the equations

(1) x + y = 27

(2) 0.75x + 1.25y = 27.75

Solve equation (1), x + y = 27 for x

x = 27 - y

Substitute 27- y for x into equation (2)

0.75(27 - y) + 1.25y = 27.75

0.5y + 20.25 = 27.75

0.5y = 7.5

y = 15

Substitute 15 for y into equation (2)

x = 27 - 15

= 12

Answer:

65

Step-by-step explanation:

Do the opposite of what the question gives you.

Sara has the number 11. She divided by 7, so you would multiply by 7:

11 x 7 = 77

Next, Sara added 12, so you will subtract by 12:

77 - 12 = 65

65 is the number Sara was thinking of.

Here are some steps to help you

You gotta use PEMDAS:

Step 1

x^2+50x-600=x^2  You gotta Remove parenthesis

Step 2

x^2+50x−600=x^2  subtract x^2 from sides

50x-600=0

Step 3

50x-600=0  add 600 to the sides

50x=600

Step 4

50x=600  Divide the sides by 50

So therefore, your answer is x=12

Answer:

The pumpkin is not in the air

Step-by-step explanation:

The equation is

[tex]g(t)=2+23.7t-4.9t^2[/tex]

Let us find when the pumpkin will reach the ground

[tex]0=2+23.7t-4.9t^2\\\Rightarrow -49t^2+237t+20=0\\\Rightarrow t=\frac{-237\pm \sqrt{237^2-4\left(-49\right)\times 20}}{2\left(-49\right)}\\\Rightarrow t=-0.08,4.91[/tex]

So, the pumpkin will reach the ground at 4.91 seconds. Hence, at 8 seconds the pumpkin will reach the ground.

At [tex]t=8\ \text{s}[/tex]

[tex]g(8)=2+23.7\times 8-4.9\times 8^2\\\Rightarrow g(8)=-122\ \text{m}[/tex]

The height of the pumpkin is negative 122 m. This means it is lower than the ground. So, the pumpkin is not in the air 8 seconds later.

Answer:

x = 4

Step-by-step explanation:

Given

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4

Answer:

840

Step-by-step explanation:

Given the date:

Birth date = 12/24/2002

Number of digits = 8 = 8! = (8*7*6*5*4*3*2*1) = 40320

Repeated digits :

digit 2 = 4 times = 4! = (4 * 3 *2 * 1) = 24

digit 0 = 2 times = 2! = 2*1 = 2

Therefore the number of 8 digit codes that can be formed is :

8! / (4! * 2!)

40320 / (24 * 2)

40320 / 48

= 840

Hence, 840 8 digit codes can be formed

Answer:

107

Step-by-step explanation:

Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)

Multiply the original price by 80%

36 x 0.8 = 28.80

The sale price is £28.80

Answer:

the side length of the cube is 4.10

Step-by-step explanation:

The computation of the side length of the cube is shown below:

As we know that

The volume of the cube is side^3

So,

69^3 = s^3

Now the side length of the cube is

= ∛69

= 4.10

Hence, the side length of the cube is 4.10
