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

Step-by-step explanation:

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.

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).

Answer:

6 times 3 times 2 and three-fourths = 49 and one-half cm³

Step-by-step explanation:

Given prism:

- length of 3 centimeters, height of 6 centimeters, and width of 2 and three-fourths centimeters

length: 3 cm

height: 6 cm

width: 2.75 cm

Given statements:

6 times 3 + 2 and three-fourths = 20 and three-fourths cm³

6 times 3 times 2 and three-fourths = 49 and one-half cm³

6 + 3 + 2 and three-fourths = 11 and three-fourths cm³

3 and 2 and three-fourths = 8 and one-fourth cm³

Rectangular prism:  

Triangular prism:  

Cylinder:  

It is a rectangular prism, therefore, the volume is 49.5 cm³

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°

Answer:

60

Step-by-step explanation:

Answer:

60º

Step-by-step explanation:

Since the angle is a right angle, which is 90º, all you have to do to find angle s is subtract 30 from 90, which gives you 60

Answer:

60 one-degree turns

Step-by-step explanation:

60/1 = 60

There are 60 one-degree turns when Jane's mom turned her steering wheel 60 degrees option first is correct.

It is defined as the numerical quantity that gives an idea about object length, width, orientation, and many more. It can be used to compare two objects.

Jane's mom was driving and turned her steering wheel 60 degrees.

We know that 60 degrees are an acute angle which is less than 90 degrees and at 60 degrees there are 60 one-degree.

When Jane's mom turned the steering wheel of the car there are a number of 60 one-degree turns.

Thus, there are 60 one-degree turns when Jane's mom turned her steering wheel 60 degrees option first is correct.

Answer:

480

Step-by-step explanation:

8 x 6 x 10 = 480

hope this helps but im probably wrong cuz im also horrible at math-

No, this is not a random sample.

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:

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

Answer:

First of all, the subjects Tammy used were from her math class. And of course, people from a math class probably like math more than other subject. Otherwise, why are they in math?

Answer:

1. A fossil is the remains of a once living animal from long ago. Fossils can be Bones, Shell, Exoskeleton, stone prints and more.

2. A observation is something seen and physically recorded as in a inferences is a guess or idea that needs to be supported BY EVIDENCE.

4. For a fossil to be fossilized it needs to be covered in sediment which prevents the fossil from decaying.

5. I THINK that's false

Answer:

1) Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks.

A fossil can preserve an entire organism or just part of one. Bones, shells, feathers, and leaves can all become fossils.

Fossils can be very large or very small. Micro-fossils are only visible with a microscope. Bacteria and pollen are microfossils. Macrofossils can be several meters long and weigh several tons. Macrofossils can be petrified trees or dinosaur bones.

Preserved remains become fossils if they reach an age of about 10,000 years. Fossils can come from the Archaeaean Eon (which began almost 4 billion years ago) all the way up to the Holocene Epoch (which continues today). The fossilized teeth of wooly mammoths are some of our most "recent" fossils. Some of the oldest fossils are those of ancient algae that lived in the ocean more than 3 billion years ago.

2)It is important to understand that an observation is something that can be easily seen whereas an inference is a guess or idea that needs to be supported by evidence. For example, students can make the observation that a gecko has four short, skinny legs.

3) I don't know what the simulation is, but I'm guessing that one observation could be made about the amount of time that a certain amount of organisms fossilize on the beach, the floodplain and the upper river.

4) Sediment (soon after death)

5) True
