Answer:

352 cm

Step-by-step explanation:

The circumference of a circle is given by the radius times 2 times π:

2•56•3,14 = 351,68 ≈ 352 cm

Answer:

30

Step-by-step explanation:

15=30

x=60

cross multiply

30×x=60×15

30x=900

x=30

so Judah rides his bike 30 miles in one hour

Answer:

30 miles

Step-by-step explanation:

multiply 15 miles by 2 and 1/2 by 2 to get 30 miles an hour.

Answer:

9

Step-by-step explanation:

i hope this helps!

Answer: 9

Step-by-step explanation:

If we add 10 plus 3 that equals 13 and then we multiply that by 7 because of the pemdas rule that equals 91. then we subtract 91 by 82 and that equals 9.

Hope This Helps! :P

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

C. x=23

Step-by-step explanation:

180=(5x+11)+54

Answer:

0.11

Step-by-step explanation:

if 11=100 and thats 100% find 10% which is 1.1 so 1% would be 0.11 i think :) im not the greatest at maths but hope this helps :)

Answer: 0.11

Step-by-step explanation:

11 times 0.01 equals 0.11

Answer:

75

Answer:

85 seconds

Step-by-step explanation:

1min=60 seconds

60+25 seconds =85 seconds

Answer:

bottom left is 1:30

Step-by-step explanation:

Answer:

1)

[tex] \frac{28}{5} [/tex]

or

[tex]5 \frac{3}{5} [/tex]

2)

[tex] \frac{10}{7} [/tex]

or

[tex]1 \frac{3}{7} [/tex]

4)

[tex]4[/tex]

5)

[tex] \frac{ 18}{7} [/tex]

or

[tex]2 \frac{4}{7} [/tex]

6)

[tex]10[/tex]

Answer:

1. 28/5

2. 10/7 or 1 3/7

3. 13/5 miles or 2.6 miles

4. 4

5. 18/7 or 2 4/7

6. 10

7. 9 muffins

8. 81 feet

9. 27 flowers

Step-by-step explanation:

1. 4 1/5 • 2 2/3 = 28/5 or 5 3/5

2. 2 6/7 • 2 1/4 = 10/7

3. 3 1/4 • 4/5 = 13/5

4. 6 • 2/3 = 4

5. 2/7 • 9 = 28/7

6. 5/6 • 12 = 10

7. 24 • 3/8 = 9

8. 27 • 3 = 81 (multiply 27 by 3)

9. 45 • 3/5 = 27

I hope this helps, good luck! ;D

BTW I feel your pain, I really wish you the best of luck!

Hi there! Before we start with your problem. Recall the Trigonometric Function of (-x) first.

Now what we need to do is to imagine a unit circle. We know that angle (-x) rotate clockwise while (x) rotates counterclockwise.

Now imagine if it rotates clockwise, it:d start at the fourth quadrant first. That means the y-value is negative while x-value is positive.

We also know that (x, y) = (cos, sin)

Now move to the 2(pi)/3.

[tex] \large{ \frac{2 \pi}{ 3} = \frac{2(180)}{3} \longrightarrow 2(60)= \boxed{120 \degree}}[/tex]

Thus, the value of 2pi/3 is 120°

Now imagine again. In a unit circle, 120° is in second quadrant if we rotate counterclockwise. But if we rotate clockwise, where would the 120° be? Remember that (-x) rotates clockwise. That's right! (-120°) is in the third quadrant. In the third quadrant, cos is negative there along with sin.

So we can conclude that:

120° is also a reference angle of 60° because of 180°-60° = 120°

Thus,

[tex] \large{cos( - \frac{2 \pi}{3} )= cos( - 120 \degree) = cos(120 \degree) \longrightarrow - \frac{1}{2} }[/tex]

Answer/Conclusions

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

c i believe

Step-by-step explanation:

Answer:

it would be c!! i can edit in an explanation if needed! :)

Answer:

I believe the answer is D or B

Step-by-step explanation:

Answer:

for number one it would be -2, 3

Step-by-step explanation:

if you were to graph it out into paper (2,3) and mirror it across the vertical axis (y) then you end up with (-2,3)

Answer:

11

Step-by-step explanation:

32.5 divided by 5 = 6.5

71.5 divided by 6.5 = 11

the answer is 11

Answer:

11 tickets

Step-by-step explanation:

Divide $32.50 by 5 to find the price per ticket

Divide $71.50 by $6.50 (the ticket cost) to get the number of tickets that can be bought with $71.50

Hope this helps :)

Answer:

Area = 25 square units

Step-by-step explanation:

Parallelogram : b =(6 - 1) = 5  h, = 2

Rectangle : length= (8 - 3) = 5units, width= (5 - 2) = 3 units

Area of Parallelogram = b x h = 5 x 2 = 10

Area of Rectangle = Length x Breadth = 5 x 3 = 15

Total Area = 10 + 15 = 25 square unit

Answer:

45 degrees

Step-by-step explanation:

An octagon is 360 degrees and 360 divided by 8 is 45.
