Alan's dogs have a total of 24 legs (l). if each dog has 4 legs, which equation gives the number of dogs (

1 answer:

3 0

4d = 24 would be the right equation. To double check you would divide both sides by 4 (the number of legs) to find the amount of dogs.

The coordinates of the endpoints of directed line segment ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2, the coordinates of B are

Greeley [361]

Answer:

The coordinates of B are (1,-5).

Step-by-step explanation:

To find the coordinates of point $B$ we will apply section formula.

Its used to find out if any line segment is of any $m_1: m_2$ ratios.

As the lie segment is joining the points internally we will use section formula for internal points.

Lets say that $B$ is having coordinates $(k,l)$ then $k=\frac{m_1(x_2) +m_2(x_1)}{m_1+m_2}$ and $l=\frac{m_1(y_2) +m_2(y_1)}{m_1+m_2}$

Now we have $A=(8,7)$ we call it $(x_1,y_1)$ then $C=(7,-13)$ we call it $(x_2,y_2)$ .

And $m_1=3$ , $m_2=2$

Plugging all the values in section formula we have.

$k=\frac{m_1(x_2) +m_2(x_1)}{m_1+m_2}$

$k=\frac{3(7) +2(-8)}{2+3}$

$= \frac{21-16}{5}= 1$

Similarly

$l=\frac{m_1(y_2) +m_2(y_1)}{m_1+m_2}$

$l=\frac{3(-13) +2(7)}{2+3}$

$l=\frac{-39+14}{5}= -5$

So the coordinates of $B =(1,-5)$

aev [14]

Answer:

1. The ratio of milk cartons taken to total milk cartons,

70 - 10 = 60 were taken

73/100 is the ratio of milk cartons taken to total milk cartons

2. The ratio of milk cartons remaining to milk cartons taken

10 / 60 is the ratio of milk cartons remaining to milk cartons take

maks197457 [2]

Answer:

The difference between the heights of the poles is 10m

Step-by-step explanation:

The distance between poles is 24 m

The length of the cable is 26m

You first use the Pythagoras' theorem to calculate the vertical distance between the end of one pole and the end of the other one.

$c_2=\sqrt{h^2-c_1^2}\\\\c_2=\sqrt{(26m)^2-(24m)^2}=\sqrt{100}m=10m$

The difference between the heights of the poles is 10m

The higher pole has height of 50m

Then, the lower pole has a height of 50m - 10m = 40m
