Answer:

V=Π2h

use for the answer

No, this is not a random sample.

1) False

Adjacent angles must share a common side/ray.

2) B and D

Adjacent angles are those that are directly next to each other and share a common side.

3) C

Angles 1 and 2 are congruent. Angles 3 and 4 are congruent. Both of these pairs have angles that are opposite each other.

4) B

Angles 1 and 2 add up to 180. Angles 3 and 4 add up to 180. Both of these pairs of angles are supplementary.

5) A

These angles are directly next to each other and share a common side.

Answer:

(2,0), (6,0)

Step-by-step explanation:

X-intercepts are just points that are on the x-line. The two points that are on the x-line is (2,0) and (6,0). Therefore, those are the x-intercepts.

If this helps please mark as brainliest

Answer:

(2,0)

(6,0)

Step-by-step explanation:

The X intercept is any point that touches the X-axis on the graph (The X-axis the line that goes from left to right).

From looking at this parabola, we can see that it touches the x-axis twice, at the points (2,0) and (6,0).

Please give me brainliest if I helped!

Answer:

7/23.

Step-by-step explanation:

P(not A) = 1 - P(A)

= 1 - 16/23

= 23/23 - 16/23

= 7/23.

Answer:

[tex]80\:\mathrm{km^2}[/tex]

Step-by-step explanation:

The area of a triangle can be given by [tex]A=\frac{1}{2}bh[/tex], where [tex]b[/tex] is the base of the triangle and [tex]h[/tex] is the height of the triangle.

As marked in the diagram, we are given the following:

[tex]A=\frac{1}{2}bh=\frac{1}{2}\cdot 10\cdot 16=\boxed{80\:\mathrm{km^2}}[/tex]

Answer:

Hello! answer: 80 km

Step-by-step explanation:

To find area in triangles you can do

base × height ÷ 2 or base × height × 1/2

10 × 16 = 80 therefore the area is 80 km

Answer:

A = 8, B = 6, C = 4 , D = 7

Top = 29

Side = 20

Step-by-step explanation:

Last row : A + A + A + A = 32 ==> A = 8

First row : D + A + D + D = 3D + 8 = 29

                                          3D = 21 ==> D = 7

Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27

                                                          2B = 12 ==> B = 6

Third column : D + A + C + A = 27

                      7 + 8 + C + 8  = 27 ==> C = 4

Answer: the brother is 20 and the sister is 9

Step-by-step explanation:

29 - 11 = 18  18 divided by 2 is 9

9+11 is 20 the brothers age so the sister is 9

Answer:

h=square root of 55

area of triangle=15*square root of 5

Step-by-step explanation:

Answer:

a. 7.4 cm

b. 22.2 cm²

Step-by-step explanation:

a. Apply Pythagorean theorem to find h.

c² = a² + b²

Where,

c = 8 cm

a = 3 cm

b = h cm = ?

Plug in the values

8² = 3² + h²

64 = 9 + h²

64 - 9 = h²

55 = h²

h = √55

h ≈ 7.4 cm

b. Area of the triangle = ½*bh

b = 6 cm

h = 7.4 cm

Area = ½*6*7.4

Area = 22.2 cm²

its D for 10 because there are four prime numbers in the equation 2, 3, 5, 7

Answer:

Each angle is 60°

Step-by-step explanation:

The 2 angles are equal to each other because they're alternate exterior angles:

10x - 20 = 7x + 4

10x - 7x = 4 + 20

3x = 24

x = 8

10x - 20

10(8) - 20

80 - 20

60

Since these angles are exterior angles, their angle measures are equal so they both are 60°
