Answer:
Step-by-step explanation:
To know the number of rows of the beads are used on the bookmark, we just need to divide.
Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.
We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.
Then, the division is
Therefore, there are 50 beads on the bookmark.
To Euclid, a postulate is something that is so obvious it may be accepted without proof.
A. A straightedge and compass can be used to create any figure.
That's not Euclid, that's just goofy.
B. A straight line segment can be drawn between any two points.
That's Euclid's first postulate.
C. Any straight line segment can be extended indefinitely.
That's Euclid's second postulate.
D. The angles of a triangle always add up to 180.
That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."
Answer: B C
The 4 equations that equals 16 will be , , and .
In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign "=".
Equations often contain algebra. Algebra is used in Math when you do not know the exact number in a calculation.
But, in given question, there is no variable in the statement so we use only constant to make equation which is equal to 4.
Now the equation will be,
