Let ABC be the triangle (with A as summit) and BC its base which is at the  same time the diameter of the semi-circle. Let AH be the altitude of ABC.

Length of the Base BC (which is also the diameter of the semi circle) = 4 units and consequently the radius = 2 units
Length of the altitude AH = 5 units, hence:
a) the Area of ABC = (Base x Altitude)/2 = (4 x 5)/2 = 10 units²
b) the area of the semi circle is: (π x R²)/2 = (π x 2²)/2 = 6.28 units²

Total area = 16.28 units²

the slope of line PQ is m= 1/4. find the equation of the line that is parallel to line PQ and that has the y intercept b= -3
nevsk [136]
For this case we have that the generic equation of the line is given by:
 y = mx + b

 Where,
 m: slope of the line
 b: intersection with the y axis.
 Since the line is parallel to PQ, then the slopes are equal.
 We have then:
 m = 1/4.

 On the other hand we have:
 b = -3

 Substituting values we have:
 y = (1/4) x - 3
 Answer:
 The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
 y = (1/4) x - 3

What is the value of x?
Elanso [62]
Since all the angles are congruent, the sides must be congruent too.


So, just have one equation on one side equal to another.

5x= 3x+6

Subtract 3x from both sides.

2x=6

Divide 2 into both sides.

x=3.

We can check this by seeing if all the sides are the same.

5(3)= 15

6(3)-5= 15

3(3)+6= 15

I hope this helps!

Hank’s Fried Chicken has $1,692 extra this month to give its employees as a bonus. Each employee received $53 as their bonus. Ho
mina [271]

Given:

Total amount of bonus = $1,692

Bonus received by each employee = $53

To find:

The Number of people work for Hank’s Fried Chicken.

Solution:

We need to divide the total bonus by the bonus of each employee to get the number of people work for Hank’s Fried Chicken.

\text{Number of people}=\dfrac{\text{Total amount of bonus}}{\text{Bonus received by each employee}}

\text{Number of people}=\dfrac{1692}{53}

\text{Number of people}=31.92453

Number of people must be whole number. So, approx the value to the preceding whole number.

\text{Number of people}\approx 31

Therefore, 31 people work for Hank’s Fried Chicken.
