The triangles below are similar. What is the value of x ?

Mandarinka [93]

Answer:

Step-by-step explanation:

Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation

$\frac{AD}{AB} =\frac{DE}{BC}$

$\frac{2}{6} = \frac{x}{12}$

$6x = 24\\x=4$

Thus the value of x is 4

IrinaK [193]

Answer:

h = 6 units

Step-by-step explanation:

The formula for the volume of a tetrahedron is given as :

V = sh

Where

s is area of base and h is height

Put s = 8 and V = 48 to find h as follows :

$h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6$

So, the height of the tetrahedron is 6 units.

Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter

galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

$x*0,04+(100000-x-y)*0,05+y*0,06=5250$

From the equation it is found that:

$y=25000+x$

Instead of y, if we put 25000+x the equation will be as following:

$x*0,04+75000*0,05+(25000+x)*0,06=5250$

From the equation it is found that:

$x=5000$

Short-Term investment is 5000$

$x+25000=y$

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$
