Answer:

10000 possible combinations

Step-by-step explanation:

Number of digits = 4

Range of values of each digit = 0 - 9

Number of digits in range = 10

Hence, each digit could be = (1 - 10)

1st digit = 10

2nd digit = 10

3rd digit = 10

4th digit = 10

Total possible combination :

10 * 10 * 10 * 10 = 10000 possible combinations

Step-by-step explanation:

Answer:

b = -1

Step-by-step explanation:

here's your solution

=> 7b - 2/5 = 6b - 7/5

=> 7b - 6b = -7/5 + 2/5

=> b = (-7+2)/5

=> b = -5/5

= b = -1

hope it helps

Answer:

b = -1

Step-by-step explanation: I put all the like terms together by moving 6b and -2/5, which then changed their signs to negative and positive, respectively.

7b-2/5 = 6b-7/5

7b-6b = 2/5-7/5

b = -1

I hope this helps. :)

Answer:

-4

Step-by-step explanation:

Given the expression

h(x) = -x^2 +4x

h(-2) = (-2)^2 + 4(-2)

h(-2) = 4  + (-8)

h(-2) = 4 -  8

h(2) = -4

Hence the value of the function when x = -2 is -4

Answer:

4

Step-by-step explanation:

3/2x -1 = 5

then

3/2x = 5+1

then

3/2x = 6

then

x = 6 / (3/2)

then

x = 6 *2/3

then

x = 4

Answer:

21.5sqft

Step-by-step explanation:

The area of the square is 10ft*10ft = 100sqft

The area of the circle is 5ft*5ft*pi = 25pi sqft

We're supposed to use 3.14 for pi, so the circle is around 25*3.14 sqft = 78.5sq ft

The area left over is 100sqft - 78.5sqft = 21.5sqft

Answer:

21.5 sq. feet

Step-by-step explanation:

Answer: $1,560

Step-by-step explanation:

Assume the computer's price is x.

This means that expressing the printer in terms of x would be:

= 30% * x

= 0.3x

These two put together represent the cost of $2,028

Expression is:

x + 0.3x = 2,028

1.3x = 2,028

x = 2,028/ 1.3

x = $1,560

Computer was $1,560

Printer was therefore:

= 1,560 * 30%

= $468

Answer:

12mm (triangle)

165mm (whole shape)

Step-by-step explanation:

The triangle is 6 x 4 = 24 ÷ 2= 12

(divide by 2 because its a teiangle)

2nd shape is 10 x 8 = 80

3rd shape is 6 x 12 = 72

72 + 80 + 12 = 165mm

Answer:

9 teaspoons are needed

Step-by-step explanation:

multiply 3 teaspoons by 3 cups to find the answer.

the answer is 9 teaspoons.

9 teaspoons are needed for a batch that uses three cups of milk.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  hot chocolate recipe calls for three teaspoons of cocoa for every cup of milk.

We need to find multiply 3 teaspoons by 3 cups to find the answer.

Therefore,  we will use unitary method;

3 teaspoons x 3 cups = 9

Hence the answer is 9 teaspoons.

Answer:

n= 1/2  m−x

Step-by-step explanation:

m=2(x+n)

Step 1: Flip the equation.

2n+2x=m

Step 2: Add -2x to both sides.

2n+2x+−2x=m+−2x

2n=m−2x

Step 3: Divide both sides by 2.

2n/2   =  m−2x /2

n= 1/2  m−x

Answer:

24 hours

Step-by-step explanation:

The computation of the number of hours taken by Bobby to build the robot by himself is shown below:

Given that

Bobby could take 12 hours

Together they could build in 8 hours

So based on the above information

the number of hours taken by Bobby to build the robot by himself is

Let us assume the above line be x

So,

[tex]\frac{1}{8}-\frac{1}{12} = \frac{1}{x} \\\\\frac{6 - 4}{48} = \frac{1}{x} \\\\\frac{2}{48} = \frac{1}{x} \\\\x = \frac{48}{2}[/tex]

Answer:

-1 , 10   and 10 , -1

Step-by-step explanation:

hello :

if x , y  this numbers you have the system :   x+y =9.....(*)

                                                                        xy = -10.....(**)

use (*) : y = 9 - x

put this value of y in (**) : x(9-x) = -10

9x  - x² = - 10

x²-9x - 10 = 0

(x+1)(x-10)=0  means : x+1 = 0 or x -10 = 0

x = -  1   or x=10

if : x= -1    y = 9-(-1)=10

if : x= 10   y = 9-(10)=1
