Indicate below wether the equation in the box is true or false 6/12= 1/3

Hatshy [7]

Answer:

False

Step-by-step explanation:

6/12 simplifies into 1/2 (six is half of twelve) and 1/2 does not equal 1/3.

You can also plug this into a calculator and see that 6/12=0.5 and 1/3=0.333

Find the distance from the point (4,2) to the point (0,1).

vagabundo [1.1K]

Answer:

4.123 units

Step-by-step explanation:

Data provided:

Coordinates of point 1 as ( 4 , 2)

and,

Coordinates of point 2 as ( 0 , 1 )

Now,

The distance between the two point whose coordinates are given is calculated using the formula as:

distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

on substituting the values, we get

distance = $\sqrt{(0-4)^2+(1-2)^2}$

or

distance = $\sqrt{(-4)^2+(-1)^2}$

or

distance = $\sqrt{16+1}$

or

Distance = √17 = 4.123 units

Kenyon ran for 8 miles each week while training. Here is his record of the number of miles he ran.

diamong [38]

Step-by-step explanation:

Let x be the miles Kenyon ran on tuesday

Let y be the miles Kenyon ran on thursday

Given,

Mon + Tues + Wed + Thu = 8mi

$1.2 + x + 1.6 + y = 8 \\ 2.8 + x + y = 8 \\ x + y = 8 - 2.8 \\ x + y = 5.2$

also given,

$y = x + 0.4 \\ - x + y = 0.4$

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2

Using equation 1,

$x + y = 5.2 \\ x = 5.2 - y$

Substitute this equation into equation 2.

$- (5.2 - y) + y = 0.4 \\ - 5.2 + y + y = 0.4 \\ - 5.2 + 2y = 0.4 \\ 2y = 0.4 + 5.2 \\ 2y = 5.6 \\ y = 5.6 \div 2 \\ = 2.8mi$

Substitute y = 2.8 into equation 1.

$x + 2.8 = 5.2 \\ x = 5.2 - 2.8 \\ = 2.4mi$

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
