Answer:
A, C
Step-by-step explanation:
First of all, recognize that any basic arithmetic operation between a rational number and an irrational number will have an irrational result. That means, you can eliminate any answer choices that involve an irrational number.
Fractions and mixed numbers involving integers are <em>always rational</em>, so you only need to look at the radicals. You know 9 is 3×3, so is a perfect square, and √9 = 3 is rational. You know 5 is not a perfect square, so <em>√5 is irrational</em>.
Considering the above, any expression involving √5 will have an irrational result. That means you can eliminate choices B and D.
choices A and C will result in a rational number
_____
<em>Additional comment</em>
A = 6.8 +0.75 = 7.55 (rational)
C = 6.8 × 0.75 = 5.100 (rational)
H +t = 8
$6h + $7t ≤$50
h+t = 8
h +t-t=8-t
h= 8-t
$6(8-t) + $7t ≤$50
48-6t +7t≤50
48-48+t≤50-48
t ≤ 2
h=6
$6(6) + $7(2) ≤$50
36 + 14 ≤ 50
50≤50
He can buy 6 pounds of ham and 2 pounds of turkey
The unoccupied volume will be the volume of the can minus the volume of the three tennis balls.
V=HπR^2-3(4πr^3)/3
V=HπR^2-4πr^3 where H=height of can, R=radius of can, r=radius of ball
We are told H=7, R=1.5, and r=1.125 (2.25/2=d/2=r) so
V=7π1.5^2-4π1.125^3
V=15.75π-5.6953125π in^3
V≈31.58 in^3
Answer:
and 4 x 4 x 4
Step-by-step explanation:
4 to the third power, is the same as 4 x 4 x 4.
This is then equal to 64.
8 squared is also equal to 64, making it also an answer.
None of the other ones work.
