Answer 1

Answer:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Step-by-step explanation:

Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:

d = 2r

From:

d = 2r

Divide both side by 2

r = d/2

The radius is half the diameter.

Circumference (C) of a circle is given by:

C = 2πr

C = π2r

Recall:

d = 2r

C = πd

Divide both side by d

π = C/d

C = πd

Divide both side by π

d = C/π

C = πd

π = 3.14

C = 3.14 × d

Thus, the circumference is 3.14 times the diameter.

SUMMARY:

The correct statement from the above illustration is given below:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

-5 because there it can’t be positive and you can reduce the equation

it is -5.

solution:

remove parenthesis, so 12k + 3 x k + 11 = 8k - 7.

combine like terms, so 15k + 33 = 8x - 7

move the terms, so 15k - 8k + 33 = -7

combine like terms again. 7x = 7 - 33

lastly, divide by both 7 to both sides. which is 7x = -40, and that gives -5.

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0

HELP HELP HELP NO ONE HELPS ME help me plz he Temples at Abu SimbelIf you ever travel to Egypt, be sure to visit the two temples at Abu Simbel, a town on the banks of the Nile River south of Aswan. The history of their construction spans both ancient and modem times.ThenBuilt around 1250 B.C.E., the Great Temple of Ramses II and the smaller Temple of Hathor next to it were carved out of a mountainside. This was no easy job. Four 67-foot-high statues of Ramses flank the entrance to the Great Temple. Inside, three inner chambers extend two hundred feet into the rock. The ancient Egyptians excavated these rooms and their massive columns using, of course, only hand tools. They also used detailed calculations to carefully align the temple. As a result, at dawn on two days of the year, sunlight reaches into the third chamber. This room was a sacred sanctuary, containing the statues of four gods. The sun's rays light up the statues and symbolically awake them to life.NowIn the 1960s, Egypt built the High Dam to control the annual Nile floods. The lake that formed behind the dam would have covered the temples at Abu Simbel. Archeologists from Egypt and many other countries were alarmed, so they raised funds to move the mountainside. And that is what was done. Workers using handsaws cut the two temples into more than a thousand blocks. Each block weighed from 10 to 40 tons. The blocks were carried to safe ground 195 feet higher. Engineers then rebuilt the two temples inside a man-made concrete mountain. They were careful to place the Great Temple in the exact orientation of the original so that the gods of the sacred sanctuary are still awakened twice a year. This reconstruction was nearly as huge a feat as that of digging the temples from the rock in the first place.Select the correct answer.According to the author, why should a tourist go to Abu Simbel?A. The temples are a feat of ancient engineering.B. The temples are a feat of modern engineering.C. The temples are a feat of both ancient and modern engineering.
