A mailbox that is 36 inches tall is beside a tree.The length of the mailboxes shadow is 28 inches.The length of the trees shadow
mixer [17]

Answer:

10.5 feet

Step-by-step explanation:

In this problem, we have two similar triangles:

- One consists of the mailbox, its shadow and the hypothenuse

- The other one consists of the tree, its shadow and the hypothenuse

The two triangles are similar, so they have same proportions between their sides: therefore, we can apply the rule of three:

\frac{m}{s_m}=\frac{t}{s_t}

where

m = 36 in is the height of the mailbox

s_m=28 in is the shadow of the mailbox

t is the height of the tree

s_t=98 in is the length of the shadow of the tree

Solving for t, we find the height of the tree:

t=\frac{m\cdot s_t}{s_m}=\frac{(36)(98)}{28}=126 in

And since

1 feet = 12 inches

The height of the tree in feet is

t=\frac{126}{12}=10.5 ft

Vikki [24]

Answer:

0.87

Step-by-step explanation:

According to the scenario, computation of given data are as follows,

As, each must be activated, this shows that components are in series.

So, we can calculate reliability of system by using following formula,

System reliability with components in series = System reliability 1 × System reliability 2 × System reliability 3 × System reliability 4

So, overall system reliability  = 0.97 × 0.99 × 0.97 × 0.93

overall system reliability = 0.866 or 0.87
