Answer: $18.25

Explication: (19 x 5) + (43 x 10) + (24 x 25) + (14 x 50) = 1,825 —> $18.25

1. M is the midpoint of LN and O is the midpoint of NP.
Reptile [31]
1. M is the midpoint of LN and O is the midpoint of NP. This makes the triangle MNO equal to half of LNP. Then you can get this equation
MO= (1/2) LP

If you insert MO = 2x +6 and LP = 8x – 20 the calculation would be:
2x+6= (1/2)( 8x-20)
2x+6= 4x-10
2x-4x= -10 - 6
-2x= -16
x=8

2. Centroid is the point that intersects with three median lines of the triangle. The centroid should divide the median lines into 1:2 ratio. In AC lines, A located in the base so A.F:FC would be 1:2

Then, the answer would be:
A.F= 1/(1+2) * AC
A.F= 1/3 * 12= 4

FC= 2/(1+2) * AC
FC= 2/3 * 12= 8

3. Since
∠BAD=∠DAC
∠ABD=∠ACD
AD=AD
The triangle ABD and ACD are similar. You can get this equation
BD=DC
x+8= 3x+12
x-3x= 12-8
-2x=4
x=-2

DC=3x+12= 3(-2) +12= 6

4. Orthocenter made by intersection of triangle altitude
A
BC lines slope would be (-4)-(-1)/1-4= -3/-3= 1. The altitude line slope would be -1, the function would be:
y=-x +a
0= 1+a
a=-1
y=-x-1
B
AC lines slope would be (-4)-(-1)/1-0= -3. The altitude line slope would be 1/3, the function would be:
y=1/3x+a
-1=1/3(4)+a
a=-7/3
y=1/3x - 7/3

C
BC lines slope would be (-1)-(-1)/4 = 0/4. 
The line would be 
0=x+a
a=-1
0=x-1
x=1

y=-x-1 = 1/3x-7/3
-x-(1/3x)=-7/3 +1
-4/3x= -4/3
x=1

y=-x-1
y=-1-1= -2
The orthocenter would be (1,-2)

5. 
a. Circumcenter: the intersection of perpendicular bisector lines<span>
b. Incenter: the intersection of bisector lines
c. Centroid: </span>the intersection of median lines<span>
d. Orthocenter: </span>the intersection of altitude lines

If 1/4 inch= 8 feet, how many inches would 136 feet be
Paha777 [63]
Answer: 4.25 inches of 4 and 1/4 inches.

Explanation: Use the information already given to you 1/4 of a inch = 8 ft. So if you have 4/4 of an inch that would equal one inch and one whole inch would equals 32 ft. ( 8 x 4 )Divide 136 by 32 and you’ll get your answer.

Solve the equation 3p (3p - 8) - 8 = 9p ( p - 3 + 4
pentagon [3]

Answer:

p= \frac{-8}{33}

Explanation:

Given:

3p (3p - 8) - 8 = 9p ( p - 3 + 4)

To Find:

Value of p=?

Solution:

Before solving this equation,  we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.  

Now we will solve the both right and left hand side of the equation  

3p (3p - 8) - 8 = 9p ( p - 3 + 4)

9p^2-24p-8=9p^2+9p

Gruoping the like terms we get,

9p^2-9p^2-24p-9p=8

After solving the both right hand and left hand side of the equation  

-33p=8

And we get the value of p as  

p= \frac{-8}{33}

Which is an equation in point-slope form for the given point and slope?
Mashutka [201]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 4 and (a, b) = (- 3, 7), hence

y - 7 = 4(x - (- 3)), that is

y - 7 = 4(x + 3) ← second equation in the list
