How many groups of 60 equal 300

hichkok12 [17]

Okay, ask yourself this : how many times does 6 goes into 30?

6 and 1 = 6
6 and 2 = 12
6 and 3 = 18
6 and 4 = 24
6 and 5 = 30

6 goes into 30 a number of 5 times. And so that means that :

60 and 1 make 60.
60 and 2 make 120
60 and 3 make 180.
60 and 4 make 240
60 and 5 make 300

FIVE (5) groups of 60 make 300.

(2,-1) <br> y-intercept -3 <br> slope 1/2<br><br> Write an equation with the given info above.

jek_recluse [69]

y-intercept -3

slope 1/2

is sufficient info with which to write an equation for a straight line:

y = mx + b becomes y = (1/2)x - 3.

You should check this by determining whether or not (2,-1) satisfies this equation.

in one day a truck delivered 48 tonnes of sand to a building site. the first three loads measured 11.25 tonnes, 12.76 tonnes, an

brilliants [131]

Answer:

11.17 tonnes was in the fourth and final load.

Step-by-step explanation:

11.25 + 12.76 + 12.82 = 36.83 > total of the first 3 loads.

x = 4th load.

36.83 + x = 48

x = 48 - 36.83

x = 11.17

Which is the graph of a quadratic equation that has a positive discriminant?

masya89 [10]

If the discriminant is positive,that means that there are roots that are real and therefore, when y=0, the roots are there and for the quadratic to meet it has to go down (or up if in ax²+bx+c a is negative). If the discriminant is 0, that means that since the x value of the vertex is -b/2a and if you have
x= $\frac{-b+- \sqrt{b^2 -4ac} }{2a} 
$ and b^2-4ac=0, we're left with 0 and we are therefore left with -b/2a as the vertex and the vertex being the x intercept. If the discriminant is negative, that means that there is no y intercept and the vertex therefore has to be over y=0
