Heather wants to buy a new refrigerator, but she only has room for one that is 18 ft3 or less. which set of dimensions represent a refrigerator that heather can buy?
a) 2 ft. wide x 2.5 ft. long x 3 ft. tall
b) 2 ft. wide x 2.5 ft. long x 4.5 ft. tall
c) 2.5 ft wide x 3 ft. long x 4 ft. tall
d) 2.5 ft. wide x 2 ft. long x 4 ft. tall

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
