Black Americans in Flight, a mural honoring several aviation pioneers, also commemorates the 1992 spaceflight of astronaut Mae Jemison.

<h3>Who is Mae Jemison?</h3>

Mae Carol Jemison, an American engineer, physician, and former NASA astronaut, was born on October 17, 1956. When she worked as a mission specialist on the Space Shuttle Endeavour, she became the first black woman to visit space. Jemison entered the NASA astronaut corps in 1987 and was chosen to fly on the STS-47 mission, which took place from September 12–20, 1992. During this mission, she orbited the Earth for almost eight days.

Jemison became the first African American woman in space on September 12, 1992, along with six other astronauts travelling on board the Endeavour for mission STS47. Jemison has won numerous prizes and been given honorary doctorates in honour of her achievements.

Please please please help me with this. I can't remember how to work this problem out. If someone could explain to me how to do

If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)

Find the circumferences of the two circles circle a has a radius of 21 meters and circle b has a radius of 28 meters Is the rela

Feliz [49]

Answer:

The circumference for circle a is $\\ C = 131.9430$ m.

The circumference for circle b is $\\ C = 175.9240$ m.

The relationship between the radius of a circle and the circumference (the distance around the circle) is constant and is the same for all circles and can be written as $\\ \frac{C}{r} = 2\pi$ or, in a less familiar form, $\\ \frac{r}{C} = \frac{1}{2\pi}$ . The number $\\ \pi$ is constant for all circles and has infinite digits, $\\ \pi = 3.14159265358979....$ .

Step-by-step explanation:

The circumference of a circle is given by:

$\\ C = 2*\pi*r$ [1]

Where

$\\ C$ is the circle's circumference.

$\\ r$ is the radius of the circle.

And

$\\ \pi = 3.141592....$ is a constant value (explained below)

We can say that the distance around the circle is the circle's circumference.

The circumferences of the two circles given are:

Circle a, with radius equals to 21 meters ( $\\ r = 21m$ ).

Using [1], using four decimals for $\\ \pi$ , we have:

$\\ C = 2*\pi*r$

$\\ C = 2*3.1415*21$ m

$\\ C = 131.9430$ m

Then, the circumference for circle a is $\\ C = 131.9430$ m.

Circle b, with radius equals to 28 meters ( $\\ r = 28m$ ).

$\\ C = 2*3.1415*28$ m

$\\ C = 175.9240$ m

And, the circumference for circle b is $\\ C = 175.9240$ m.

We know that

$\\ 2r = D$

That is, the diameter of the circle is twice its radius.

Then, if we take the distance around the circle and we divided it by $\\ 2r$

$\\ \frac{C}{2r} = \frac{C}{D} = \pi$

This ratio, that is, the relationship between the distance around the circle (circumference) and the diameter of a circle is $\\ \pi$ and is constant for all circles. This result is called the $\\ \pi$ number, which is, approximately, $\\ \pi = 3.141592653589793238....$ (it has infinite number of digits).

We can observe that the relationship between the radius of a circle and the circumference is also constant:

$\\ \frac{C}{2r} = \frac{C}{D} = \pi$

$\\ \frac{C}{2r} = \pi$

$\\ \frac{C}{r} = 2\pi$

However, this relationship is $\\ 2\pi$ .

We can rewrite it as

$\\ \frac{r}{C} = \frac{1}{2\pi}$

And it is also constant.

What are the base pairing rules in terms of DNA

Vlada [557]

Answer:

The rules of base pairing (or nucleotide pairing) are:

A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T)

C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

13/8

Step-by-step explanation:

never add the bottom number in a fraction you were on track with changing 1 and 3/8 to a normal fraction than you were supposed to get the same denominator aka bottom number so you can add them up so you would change 1/4 to 2/8 add them up to get 13/8
