Answer:
125
Step-by-step explanation:
6 and 7 are on a straight line (180 degrees)
Angle 2 is equal to Angle 6
Therefore 180 - Angle 6 = Angle 7
180 - 55 = 125
To find angle 7, we know it’s gonna be supplementary which will equal 180 degrees. So 180-55=125
The answer is 125 degrees

How do you solve 2x=10
Answers
Divide both sides by 2 so x=5 (Because 10 divided by 2 is 5 and 2x turns into just x)
Hello!!
So when we have 2x = 10 we are looking for what x equals. This means you'll want to eliminate what you can to get your answer. What you do on one side must be done on the other. Let's give that a go, sha'll we?
2x = 10
We need to use the inverse operation to eliminate a factor. Since 2x is 2 times x we'll have to divide it.
2x/2 = 10
2 divided by 2 cancels each other out and leaves us with the following;
x = 10
So, x = 10

The perimeter of a square field is 6400m. Find the cost of reaping the field at Rs.35 per 100 sq. m.
Answers
Answer:
side= 6400/4
=1600
therefore the area= 1600*1600
2560000
cost of reaping 100sq.m.=35
cost of reaping 1sq.m= 0.35
cost of reaping 2560000m sq= 2560000*0.35
= 906000

Answer:
Alternate Interior ∠s: 3 & 5, 4 & 6.
Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.
Alternate Exterior ∠s: 1 & 8, 2 & 7.
Consecutive ∠s: 3 & 6, 4 & 5.
Step-by-step explanation:
Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.
Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.
Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.
Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.
Good luck.

A certain hydraulic system operates at 6,000 PSI. Complete the percentage change in the volume of oil in the system as the pressure is increased from zero to 6,000 PSI if the oil has a Bulk Modulus of 186,000 PSI.
Answers
Answer:
the percentage change in the volume of the oil is -3.22%
Step-by-step explanation:
The computation of the percentage change in the volume of the oil is given below:
= -(6,000 - 0) ÷ (186,000)
= -3.22%
This negative sign represents the decrease in the volume
Hence, the percentage change in the volume of the oil is -3.22%

On a scale drawing,1 in represents 8 feet. What is the actual length of a room that measures 3.4 inches
Answers
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2

Answer:
[tex]y-1=6(x+5)[/tex]
Step-by-step explanation:
The given point is (-5, 1) and the slope is 6.
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-5, 1) be (x₁, y₁) and we will substitute 6 for m. Therefore:
[tex]y-(1)=6(x-(-5))[/tex]
