Answer:

60%

Step-by-step explanation:

0.(6) is just not proper mathematical format.  

I will assume you meant 0.6.

Then the equivalent percentage would be 0.6(100%), or 60%

Answer:

X=3

Step-by-step explanation:

2 times 7x = 14x

2 times -6 = -12

(÷14)

X=3

Answer:

19.2

Step-by-step explanation:

You have to trust me, this answer is correct. But here's my solution:

With the formula

Distance=Speed multiplied by Time, we can infer that Speed=Distance/Time.

But we only have one variable (Speed) in the two we need (Speed and Time), we have to pretend we have both variables. You can put the time as 1 hour because that's the most basic unit. Note that this strategy will also work with 2 hours, 3 hours, or any measure of time.

So now for distance, let's see how fast a car can travel 24 miles. When going at 24 mph, then it'll take 1 hour. With 16 mph, then it'll take 1 hour and 30 minutes, so 1.5 or 3/2 hours.  

Now we have the distance, which is 2 times 24 (Because the 24 mph and 16 mph both traveled 24 miles), equaling 48, and time, which is 1 hour plus 1.5 hours, which is 2.5 hours.

Now we use the formula Speed=Distance/Time, with 48/2.5=19 1/5 or 19.2

Step-by-step explanation:

Answer:

[tex]y=\displaystyle\frac{1}{2} x-3[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)

1) Determine the slope (m)

[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (4,-1) and (0,3)

[tex]m=\displaystyle\frac{-1-(-3)}{4-0}\\\\m=\displaystyle\frac{2}{4}\\\\m=\displaystyle\frac{1}{2}[/tex]

Therefore, the slope of the line is [tex]\displaystyle\frac{1}{2}[/tex]. Plug this into  [tex]y=mx+b[/tex] :

[tex]y=\displaystyle\frac{1}{2} x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\displaystyle\frac{1}{2} x+b[/tex]

The y-intercept occurs when x=0. Because we're given that (0,-3), the y-intercept is therefore -3.

[tex]y=\displaystyle\frac{1}{2} x-3[/tex]

Answer: 0.6 Liters of powdered milk can produce 60 cups of milk.

Explanation: 120 grams of powdered milk makes 12 cups of milk. 120 divided by 12 is 10. 60 times 10 is 600. So 600 grams of powdered milk to make 60 cups of milk. That is equal to 0.6 kilograms and that is equal to 0.6 liters.

Step-by-step explanation:

Answer:

c ≤  4 1/3  

Step-by-step explanation:

10.25 + 2.25c ≤ 20    solve the equation if there was an = in the equation

10.25 + 2.25c = 20

-10.25            = -10.25

          2.25c = 9.75

                   c = 9.75 ÷2.25

                    c = 4.3333

                       [tex]c = 4\frac{1}{3}[/tex]

Now replace the ≤ into the equation:  

c ≤  4 1/3

Answer:

1dm = 10cm

Simple as it is

Answer:

The term “Deci” means one-tenth, and therefore decimetre means one-tenth of a meter. Since a meter is made up of 100 cm, one-tenth of 100 cm is 10 cm. Thus one decimeter measures 10 cm.
