Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes

Find the slope and y intercept of the graph of the graph of each equation.
AleksandrR [38]
Solve each equation for y and then the slope is m and y-intercept is b as in:
y = mx+b

So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1

Hope this helps.

The floor of the restaurant is a square of sides 28m. The floor is covered with square tiles of sides 40m. Calculate the total n
lisov135 [29]

Answer:

196000 tiles.

Step-by-step explanation:

The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.

The tiles are 40 cm.

If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000

So 196000 tiles.

I'm not entirely sure if that's correct, but if it helps that's awesome.

Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6         Eqn 1

-6x + 3y=-12      Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

\frac{3y}{3}=\frac{18}{3}\\y=6

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

\frac{-6x}{-6}=\frac{-30}{-6}\\x=5

Hence,

The solution set is (5,6).
