Answer:
2/3
Step-by-step explanation:
To find slope the formula is (y2-y1)/(x2-x1).
Using that we substitute the pairs.
(-4,-1), (2,3) would then be (x1, y1), (x2, y2)
so you solve from there.
the equation would be ( 3 - ( - 1 ) ) / ( 2 - ( - 4 ).
( 3 - ( - 1 ) ) / ( 2 - ( - 4 )
( 3 + 1 ) / ( 2 + 4 )
4 / 6
2 / 3
Answer:
270cm²
Step-by-step explanation:
The formula is given as
S = bh × l (s1 + s2 + h)
l = 7cm
h = 5cm
s1 = 12 cm
s2 = 13cm
b = 12 cm
Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)
= 60cm² × 7 cm(30 cm)
= 60cm² + 210 cm²
= 270 cm²
Convert everything to inches.
4 ft × 12 = 48 in
2 yds × 36 = 72 in
Multiply 48 × 22 × 72 = 76032.
The volume of the cage is 76,032 in³.
The two expressions are both rational numbers- they are ending, whole and have no decimals.
