which diagram show lines that must be parallel lines cut by a transversal

Answers

Answer: hope i helped with this answer~

Step-by-step explanation:

The fourth diagram  show lines that must be parallel lines cut by a transversal

What is Straight line?

A line is an infinitely long object with no width, depth, or curvature.

Parallel lines  refers to two lines which can be found on the same plane, at an equidistance and does not meet.

A transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry.

The fourth diagram has two same-side interior angles that are supplementary (add to 180°).

The converse of the same-side interior angle theorem states that if two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Hence, the fourth diagram  show lines that must be parallel lines cut by a transversal

What is an area of a circle?

Area of a circle is defined as the region occupied by the circle in two-dimensional plane.

Mathematically,

                         A = π (d/2)²

where d is the diameter of circle

or,                      A = π r²  

where r is the radius of circle.

Now, given diameter of tortilla is 8inches.

⇒ d  = 8inches

Since,tortilla is a circle

So, area of tortilla A = π (d/2)²

⇒ A = π (8/2)²

⇒ A = π (4)²

A = 16π square inches

Hence, required tortilla's area is 16π square inches.

Step-by-step explanation:

so 6-4=2 and if you make that negative it would be -2

Answer:

-$6 + $4 = -$2

Step-by-step explanation:

Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.

An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

x=36.1

supplementary angle = 143.9 degrees

Step-by-step explanation:

angle: x

supplementary angle: 180-x

x = (180-x)-107.8

2x = 72.2

x = 36.1 degrees

180-x =  143.9 degrees

supplementary angle = 143.9 degrees

x measures 107.8 less than 180-x

x=180-x-107.8

x=72.2-x

Add x to both sides

2x=72.2

Divide both sides by 2

x=36.1

For a science experiment, Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain. Use 1 L = 2.11 pints. Round your answer to the nearest hundredth.

Answers

Step-by-step explanation:

The concentration of Marcia's solution is:

1.0 kg / 3.0 L = 0.33 kg/L

The concentration of Bobby's solution is:

(2.0 lb × 1 kg / 2.2 lb) / (7.0 pints × 1 L / 2.11 pints) = 0.27 kg/L

Therefore, Marcia's solution is more concentrated.

What is 3000 times 1000?

Answers

Answer:

Step-by-step explanation:

The equivalent value of the equation is A = 3000000

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 3000

Let the second number be q = 1000

Now , A = pq

where A = 3000 x 1000

On simplifying the equation , we get

A = 3000 x 1000

So , the left hand side of the equation is equated to the right hand side by the value of ( 3000 x 1000 )

A = 3000000

Therefore , the value of A = 3000000

Hence , the expression is A = 3000000
