Ne cement comes out
ured before 12: 00 noon
4. ed is pouring cem
cois pouring cement for his backyard patio that has an area of 100 square feet. the cement come
of the truck at a constant rate. it is very important that he gets all the cement poured before 12: 00
when it gets too hot for the cement to be mixed properly. it is currently 11: 00 am and he has poured
square feet of concrete in the last 3 hours.
(x, y)

b. state the unit rate.
c. show the unit rate on the graph.
d. state the constant of proportionality
e. does the equation y = 25x represent this
situation? explain.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

two data sets with the same median will not have the same varaibility
