Answer:

3/4 of a liter

Step-by-step explanation:

2 - 5/4

Get a common denominator

2 *4/4 - 5/4

8/4 - 5/4

3/4

The denominator is 4 so rewrite 2 liters as a fraction with 4 as the denominator.

4/4 = 1 so 2 liters would be 8/4

Now subtract:

8/4 - 5/4 = 3/4

There is 3/4 of a liter left.

Point B has coordinates (4,1). The x-coordinate of point A is -4. The distance between point A and point B is 10 units. What a

klasskru [66]

Given:

Point B has coordinates (4,1).

The x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

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

The distance between point A and point B is 10 units.

$\sqrt{(4-(-4))^2+(1-y)^2}=10$

Taking square on both sides, we get

$(8)^2+(1-y)^2=100$

$(1-y)^2=100-64$

$(1-y)^2=36$

Taking square root on both sides, we get

$(1-y)=\pm \sqrt{36}$

$-y=\pm 6-1$

$y=1\mp 6$

$y=1-6$ and $y=1+6$

$y=-5$ and $y=7$

Therefore, the possible coordinates of point A are either (-4,-5) or (-4,7).

Answer:

D/2=r

Step-by-step explanation:

Since we want r to be by itself what we can do is divide 2 on both sides so 2 can cancel out on 2r and when you divide on both sides your left with d/2=r
