First we need to find the area of the triangle and the formula for that is A=1/2bh

Next we plug in what we have and we get the formula A=1/2(4x7)

When we do that math we get 14

Now we need to find the volume of the whole prism and the formula for this is V=Bh (big b means area of base)

When we plug in what we know we get V=14x13

Which gives us our final answer of V=182

Answer:

x-intercept: (4, 0)

y-intercept: (0, 3)

Step-by-step explanation:

The intercepts of the equation can be found by setting each variable to zero and solving for the other. The graph will be a line through the intercept points.

<h3>Intercepts</h3>

Setting x=0 and solving for y, we have ...

4y -12 = 0 ⇒ y = 12/4 = 3

Setting y=0 and solving for x, we have ...

3x -12 = 0 ⇒ x = 12/3 = 4

The intercepts are ...

x-intercept: (4, 0)

y-intercept: (0, 3)

<h3>Graph</h3>

The line will go through these intercept points.

Answer:

$Speed\ of\ car=38\ km/h$

Step-by-step explanation:

Distance Covered by Horse:

$Speed\ of\ horse=50\ km\h=50\times \frac{1000}{60}\ meter/ minute\\\\Speed\ of\ horse=\frac{2500}{3}\ meter/minute\\\\Distance\ covered\ in\ 4\ minutes=speed\times time=\frac{2500}{3}\times 4\\\\Distance\ covered\ in\ 4\ minutes=\frac{10000}{3}\ meters\\\\$

Distance covered by Car:

$Let\ speed\ of\ car=x\ meter/minute\\\\time=4\ minutes\\\\Distance\ covered=speed\times time=4\times x=4x$

$Distance\ covered\ by\ horse=Distance\ covered\ by\ car+800\\\\\frac{10000}{3}=4x+800\\\\4x=\frac{10000}{3}-800\\\\4x=\frac{7600}{3}\\\\x=\frac{7600}{3\times 4}\ meter/minute\\\\x=\frac{7600}{3\times 4}\times \frac{60}{1000}\ km/h\\\\x=38\ km/h$
