2.

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles.  We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.

Angle x isn't the same as the 40° angle so it must be its supplement.

Answer: C 140°

3.

r=1.2, h=2.9, V = (1/3) πr²h

Nothing hard here, we just plug in the numbers,

V = (1/3) π (1.2)² (2.9) ≈ 4.37310

Answer: B. 4.4 cubic inches

4.

Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is

Answer: B similar not congruent

5.

The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°

Answer: A 70°

The diagram below shows the rectangle PLUM.
Illusion [34]

Answer:

Area of rectangle PLUM = 75.00 square units

Step-by-step explanation:

Since diagonal of rectangle divides the rectangle into two equal triangles,

Therefore, area of the rectangle PLUM = 2× area of triangle PLM

By the mean proportional theorem,

In ΔPLM,

AP² = AM × AL

6² = AM × 8

AM = \frac{36}{8}

AM = 4.5 units

Area of PLM = \frac{1}{2}(\text{Base})(\text{height})

                     = \frac{1}{2}(ML)(AP)

                     = \frac{1}{2}(8 + 4.5)(6)

                     = 12.5 × 3

                     = 37.5 units²

Now area of rectangle PLUM = 2×37.5 = 75 units²

Therefore, area of the rectangle is 75.00 square units.

Which expression gives the distance between the points
Anna35 [415]

Answer:

  D.  √((2 +4)² +(5 -8)²)

Step-by-step explanation:

The distance is found using the formula ...

  d = √((x1 -x2)² +(y1 -y2)²)

Selection D has this formula properly filled in with the values ...

  (x1, y1) = (2, 5)

  (x2, y2) = (-4, 8)

My little sis needs help
lubasha [3.4K]

Answer:

603 miles in 3 days

Step-by-step explanation:

Let's find out how many miles in 1 day:

  1. 1,005 ÷ 5 = 201
  2. So, Sarah drives 201 miles in 1 day

Let's find out how many miles in 3 days:

  1. 3 days = 1 day × 3
  2. 3 days = 201 × 3
  3. 3 days = 603 miles

I hope this helps!

What’s the answer and work for this? Someone please tell me
Nadusha1986 [10]

Answer:

<h2>The averages are equal, since both are 4.</h2>

Step-by-step explanation:

2 + 4 + 6 = 12 / 3 = 4

Average of even numbers = 4

1 + 3 + 5 + 7 = 16 / 4 = 4

Average of odd numbers = 4

The averages are equal, since both are 4.

<em>Hope that helps!</em>
