Answer:

60 seconds

Step-by-step explanation:

step 1.) find how many meters it falls per second

          40m / 4sec = 10m/s

step 2.) use the equation above to find in terms of the question

          10m/s for 6sec = 10 x 6 ====> 60 seconds

Answer:

10000

Step-by-step explanation:

to know if this answer is correct you have to know the rounding rules:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Step-by-step explanation:

Answer:

Step-by-step explanation:

1/2(4x - 16) = 14

2x - 8 = 14             {add 8 to both sides}

 2x = 22               {divide both sides by 2}

   x = 11

Answer:

Equation 1: 50 + 5x = 80, Or 5(10 + x) = 80

Equation 1 answer: 6

Equation 2: 5x + 10 = 80

Equation 2 answer: 14

Answer:

12x + 2

Step-by-step explanation:

12 is multiplyed by both the x and the (1/6) since it is outside the equation.

so 12 times x = 12x since we dont know what x is

and 12 times (1/6) = (12/6) = 2

Answer:

4x+6y<=10

Step-by-step explanation:

The linear inequality that describes the graph is 4x+ 6y ≤ 10.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

As, The bold straight line passes through the points (1,1) and (-2, 3).

so, equation of line will be

(y- 1) = (3-1)/ (-2-1) (x-1)

y-1 = 2 / (-3) (x-1)

-3y + 3 = 2x - 2

-3y -2x = -5

If we multiply by 2 both side we get

-6y - 4x = -10

4x+ 6y= 10

So, the required inequality for gray area is 4x+ 6y ≤ 10.

5(3x+45)

Answer:

x=1, y=1.

Step-by-step explanation:

From the second equation:

x = 8 - 7y, so substituting for x in the first equation:

3/8(8 - 7y) + 1/3y = 17/24

3 - 21/8 y + 1/3y = 17/24

1/3y - 21/8y = 17/24 - 3

Multiply through by 24:

8y - 21*3 y = 17 - 72

8y - 63y = -55

-55y = -55

y = 1.

And  substituting for y in the second equation:

x + 7(1) = 8

x = 8 - 7

x =  1.

=3

Answer:

If b = 6 and c = 10, the value of an expression is 3.

Step-by-step explanation:

Given the expression

[tex]\frac{5b}{c}[/tex]

We have to evaluate the expression if b = 6 and c = 10.

Important Tip:

In order to evaluate the expression  [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.

As the expression is

[tex]\frac{5b}{c}[/tex]

substitute b = 6 and c = 10 in the expression

[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]

     [tex]=\frac{30}{10}[/tex]

      [tex]=3[/tex]       ∵ [tex]\frac{30}{10}=3[/tex]

Therefore, if b = 6 and c = 10, the value of an expression is 3.

6.) ∆DAY

7.) SAS

Answer:

C) 23

Step-by-step explanation:

If the computer monitor is 20 inches wide, and 12 inches high, we can solve for the diagonal by using the Pythagorean theorem.

Let a = the width, let b= the height, let c = the diagonal.

a^2 + b^2 = c^2

20^2 +12^2 =c^2

400 + 144 = c^2

544 = c^2

C is approximately equal to 23 inches.
