Answer:

How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. Also called "Ordinate"

The old man walked 2/3 of a mile in 1/2 of an hour. What is this rate in miles per hour?

Morgarella [4.7K]

If the old man walks 2/3 of a mile in 1/2 an hour, you can find how many miles he walk in one hour by setting up a fraction where distance (miles) is the numerator and the denominator is time (hours). So, (2/3)/(1/2) is the fraction. Now, we have to figure out how to make the denominator one, and we do that by multiplying is by 2. Whatever you do to the denominator you have to do to the numerator, so multiply 2/3 by 2 and 1/2 by 2.

(1/2) x 2 = 1 and (2/3) x 2 = 4/3 or 1 1/3

the old man walked 1 1/3 miles per hour

Select the correct answer from each drop-down menu. Complete the statement. The solutions of sin2x= √3/2

Answer:

henc X = 30°

Step-by-step explanation:

here is the proof

when X=30° then

sin2x = sin2×30

=sin 60°

= √3/2

or else,

putting value of X = 30° then

sin2x= 2sinxcosx

= 2×sin30°×cos30°

=2×1/2×√3/2

= 2√3/4

= √3/2

hence proved sin2x= √3/2.

-1 2/3 / (-2 1/5)<br> solve this for me please &&' thank you

dangina [55]

Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5

Now stack the fractions like this.

$\frac{ \frac{-5}{3} }{ \frac{-11}{5} }$

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

$\frac{ \frac{5}{3} } { \frac{11}{5} }$

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

$\frac{5}{3} * \frac{5}{11}$

When you do this, you just multiply top by top and bottom by bottom
