options: given, vertical angles, corresponding angles, and transitive​

Answers

Answer:

1. Given

2. Vertical angles

3. Transitive

4. Corresponding Angles

Step-by-step explanation:

1. Number one is given because it is the statement that is given

2. Number two is vertical angles because they are two opposite angles that are formed by the same lines. The statement also says they are congruent, which is true of vertical angles.

3. From the given answers 3 must be transitive because <2=<4 and <2=<6. Although alternate interior angles is also an appropriate answer.

4. Number four must be corresponding because they are on the same side of the intersection of the lines, so they are both in the top right. Also, the statement says they are congruent which is true of corresponding angles.

It is given that,

The first number is -2.2

The second number is 3.7

If we multiply -2.2 and 3.7, we will get -8.14.

But in the given case, the answer is 8.18 instead of -8.14. Hence, this is the only error.

Answers

He probably won't get too suspicious if you get 100% on three quizzes when you regularly get A's in that class.  A ninety-something percent jump to a 100 is less than a 10-point increase.  

That being said, it's still best to learn the math so that you don't become dependent on using Brainly for every question.  Maybe only use it when you're having a lot of trouble with a particular problem or concept; but some of the explanations on here are actually really helpful in teaching things.

What is the answer Timothy curtain company is making curtains for a local hotel he wants each certain to be 48 inches long at the fabric store from Vegas sold by the foot and Timothy's certain company wants to make 45 curtains how many feet of fabric but you need 1 inch equals one12 foot

Answers

Answer:

180 feet

Step-by-step explanation:

The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.

But,

1 inch = 12 feet

So that,

48 inches = x feet

⇒ x = [tex]\frac{48}{12}[/tex]

      = 4

Thus,

48 inches = 4 feet

The number of feet of fabric needed for 45 curtains can be determined as:

45 x 4 feet = 180 feet

Therefore, 180 feet of fabric would be needed to make 45 curtains.
