Hector waters his lawn if it does not rain at least 1 1/2 inches each week. it has already rained 3/8 inch this week. which inequality represents the number of inches of rain, r, still needed so hector does not have to water his lawn this week?

a. r ≥ 1 7/8

b. r > 1 7/8

c. r ≥ 1 1/8

d. r > 1 1/8

(the fractions are mixed )

the answer is C

Step-by-step explanation:

this is because he needs at least 1 1/2, it's already rained 3/8 inches, so to simplify the equation change 1 1/2 to 1 4/8 which is still equivalent to 1 1/2, then subtract 3/8 from 1 4/8 which will give you 1 1/8. now here is where it gets kind of tricky, both C and D seem to have 1 1/2, but the difference between them is the symbols > and ≥ are CRUCIAL (">" means that the number at the left is greater than the number at the right while "≥" means that the number at the left is greater than OR EQUAL TO the number at the right) so as you can see you also need to pay attention to what the text says, because it is mention quote on quote "Hector waters his lawn if it does not rain at least 1 1/2 inches each week," this means that if it's not at least (in other words the same as or more) 1 1/2 inches of rain a week, he will water his plants

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
