Which two sentences taken together provide the BEST evidence to support the idea that black holes are difficult to locate? Read the following sentences from the article. 1. This black hole is about 1,000 light-years away and each light-year is 5. 9 trillion miles (9. 5 trillion kilometers). 2. Astronomers theorize there are between 100 million and 1 billion of these small but dense objects in the Milky Way. 3. Usually, scientists can only spot them when they're gobbling up sections of a partner star or something else falling into them. 4. Astronomers think most black holes, including this newly discovered one, don't have anything close enough to swallow. Question 3 options: 1 and 2 1 and 4 2 and 3 3 and 4.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
