brilliants [131]

Answer:

25.

Step-by-step explanation:

5 ft 7 in = 5.583 ft.

We have 2 similar triangles here.

If h is the height of the tree, then:

Let AB // ED , AB = 10 units, AC = 12 units, and DE = 5 units. What is the length of AD?​
zheka24 [161]

Answer:

length of CD = 18 units.

Step-by-step explanation:

In ΔABC and ΔCED,

AB║DE and AD is a transversal line,

m∠ABC = m∠CED [Alternate interior angles]

m∠ACB = m∠DCE [Vertically opposite angles]

ΔABC ~ ΔCED [By AA property of similarity]

Therefore, by the property of similar triangles, corresponding sides will be proportional.

\frac{AB}{DE}= \frac{AC}{DC}

\frac{10}{5}=\frac{12}{CD}

CD = 6

Since, AD = AC + CD

AD = 12 + 6

     = 18 units

Therefore, length of CD = 18 units.

A man's salary is increased by $925 to $1036. Find the percentage increase. What would have been his new salary if the increase
exis [7]

Answer:

See the solutions below

Step-by-step explanation:

Initial Salary= $925

Final salary=  $1036

% increase= Change/initial *100

substitute

% increase= 1036-925/925 *100

% increase=111/925 *100

% increase=0.12 *100

% increase=12%

2. Let us find 16% of $925

=16/100*925

=0.16*925

=$148

Hence the salary would have been

=148+925

=$1073
