Angle P measures 112 degrees, what are the measures of angle N and O?
Oxana [17]
The inside angles of a triangle need to equal 180 degrees
 in this triangle the lines NP and OP are identical so the 2 unknown angles would be equal
 so the 2 unknown angles would be 180 - 112 = 68 / 2 = 34 each
 angle N & O are 34 degrees

A carpenter bought 750 nails. Each nail has a mass of 5.2×10−3 kilogram. What is the total mass, in kilograms, of the nails the
lawyer [7]

The total mass, in kilograms, of the nails the carpenter bought is 3.9 kilogram

<h3><u>Solution:</u></h3>

Given that carpenter bought 750 nails

Each nail has a mass of 5.2 \times 10^{-3} kilogram

To find: total mass, in kilograms of the nails bought

The total mass of the nails bought can be found out by multiplying number of nails bought by mass of each nail

Number of nails bought = 750

Mass of each nail = 5.2 \times 10^{-3} kilogram

total mass of the nails bought = number of nails bought x mass of each nail

\text {total mass of the nails bought }=750 \times 5.2 \times 10^{-3}

\text {total mass of the nails bought }=3900 \times 10^{-3}=\frac{3900}{1000}=3.9

Thus the total mass of nails bought is 3.9 kilogram

Prove that the diagonals of a rectangle bisect each other. the midpoint of is _____
Deffense [45]
In this attached picture, we can prove that triangles AOB and COD are congruent. ∠CDO and ∠ABO are equal because they are alternate angles. Similarly, ∠OAB and ∠OCD are equal because they are alternate angles, as well. We have a rectangle and in the rectangle, opposite sides are equal; AB = CD. Then, because of Angle-SIde-Angle principle, we can say that triangles AOB and COD are equal. If triangles are congruent, then OD = OB and OC = AO. Applying congruency to the triangles ACD and BCD, we can see that these triangles are also congruent. It means that the diagonals are equal. Since, OD = OB and OC = AO, it proves that the point O simultaneously is the midpoint and intersection point for the diagonals.

Solve for x: -2x - 5 = 4
Nata [24]

Answer:

x=−20

Step-by-step explanation:

Step by Step Solution:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    x/5-(-4)=0

Step by step solution :

STEP

1

:

           x

Simplify   —

           5

Equation at the end of step

1

:

 x    

 — -  -4  = 0

 5    

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

         -4     -4 • 5

   -4 =  ——  =  ——————

         1        5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (-4 • 5)     x + 20

————————————  =  ——————

     5             5  

Equation at the end of step

2

:

 x + 20

 ——————  = 0

   5  

STEP

3

:

When a fraction equals zero

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x+20

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x+20  = 0

Solving a Single Variable Equation:

3.2      Solve  :    x+20 = 0

Subtract  20  from both sides of the equation :

                     x = -20

One solution was found :

x = -20
