Complete each percent increase or percent decrease as a percentage of the initial amount. The first one is done for you. a. This year, there was 40% more snow than last year.
The amount of snow this year is 140% of the amount of snow last year.
b. This year, there were 25% fewer sunny days than last year.
The number of sunny days this year is
% of the number of sunny days last year,
c. Compared to last month, there was a 50% Increase in the number of houses sold this month.
The number of houses sold this month is
of the number of houses sold last month.
d. The runner's time to complete the marathon was 10% less than the time to complete the last marathon,
The runner's time to complete the marathon was
of the time to complete the last marathon,

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
