What's 2.85 tons rounded to the nearest hundredth

Answers

I think its 2.90 because the hundreth is the second to the right and its a five so it goes up to 90
2.85 tons. The hundredth spot is the second one to the right of the decimal (the 5) and since that's where you're rounding to it stays 2.85 tons :)

Josh has $25 and he wants to buy some movies. He picks one movie that costs $9.99 and two that cost $5.99 each. Which statement best describes if an exact total or an approximate total should be calculated?

A.
Josh must add the exact cost of the 3 movies so he will know if he has enough money to buy the third movie.

B.
Josh can round the prices of the movies to the nearest dollar and then add to estimate if he has enough money.

Answers

he should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents

A
B. Josh can round the prices of the movie to the nearest dollar and then add to estimate if he has enough money
This is because whether he rounds it or not, there will only be a 2 cent gap. Rounding will just make it easier to add and subtract. Hope it helps:)

Write the equation of the line that passes through the points (-1, -2), (2, 7).

Answers

Answer:

y+2=3(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(7-(-2))/(2-(-1))

m=(7+2)/(2+1)

m=9/3

m=3

y-(-2)=3(x-(-1))

y+2=3(x+1)
