HELP!!!!!ASAP!!!!!!

Answer:

$\sin( 115 \degree) = 0.906$

Step-by-step explanation:

The general point on a unit circle is given by

$x = \cos( \theta)$

$y = \sin( \theta)$

where

$\theta = 115 \degree$

is the terminal side of the angle in standard position.

Therefore

$x = \cos( 115 \degree)$

$y = \sin(115 \degree)$

lies on this circle

This angle intersects the unit circle at

$( - 0.423,0.906)$

Hence we must have

$\cos( 115 \degree) = - 0.463$

$\sin( 115 \degree) = 0.906$

Write 44 as a product of prime factors.

Ann [662]

Answer:

Hence, 11 x 2 x 2 is the product of prime factors.

Step-by-step explanation:

Let's divide by 2's.

=> 44 = 22 x 2
=> 22 x 2 = 11 x 2 x 2

Since 11 is a prime number, we cannot simplify it anymore. Hence, 11 x 2 x 2 is the product of prime factors.

Is 1.5 miles greater than 2500 yards

worty [1.4K]

Hey there!

According to our customary units of miles, 1 mile is equal to 5,280 feet - and 3 feet is a yard. That means, we have to divide 5,280 by 3 to figure out how many yards are in a mile:

5280/3 = 1760

That means that one mile is 1760 yards. But we're not finished yet. It says 1/5 miles, not one mile. Therefore, we take one half of the total distance in yards of a mile and add it to that 1760, because it's 1.5, or 1-and-a-half. Which, in technical terms means "1-plus-a-half".

We have:

1760 + 1760/2 = 1760 + 880 = 2640

Therefore, 1/5 miles, since it's 2640 yards, is greater than the 2500 yards specified in the question.

Hope this helps!

The population of a country was estimated to be 1.114 x 10^8. On this day, the population of the world was 3.853 x 10^9.

Lelechka [254]

Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × $10^{9}$ - 1.114 × $10^{8}$ = 3.7146 ×

To find the percentage of people living inside the country, we divide: $\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2}$ percent or 2.89%. Which is extremely small.
