You read 50 pages in an hour. your sister reads 40 pages in an hour. explain how to find out how many more pages you read than your sister reads in 1/2 hour?
a. i know that 50 • 40 = 2,000, so i read 1,000 more pages than my sister reads in 1/2 hour.
b. i know that 50 ÷ 40 = 5454, 5 ÷ 4 = 1 1/4, so i read 1 1/4 more pages than my sister reads in 1/2 hour.
c. because i read 10 more pages than my sister reads in 1 hour, i read 5 more pages in 1/2 hour.
d. since 5 • 4 = 20, i read 20 more pages than my sister reads in 1/2 one half hour.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
