V = lwh - πr²h
V = (4)(2)(3) - 3.14(¹/₂)²(3)
V = (8)(3) - 3.14(¹/₄)(3)
V = 24 - 3.14(³/₄)
V = 24 - 2.355
V = 21.645 ft³
V = 259.74 in³
Answer: 145
Step-by-step explanation:
you have to find what x is based on the other side
4x+15+30x-5=180
x=5
plug in 5 in 20x+45

1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
A) identify variables
Cows = C
Chickens = Ch
and
Dogs = D
are the variables
B)logical symbols
Winston can milk ten cows = 10C
and is a logical operator
and= ∧
feed ten chickens = 10Ch
but he cannot
cannot is a logical operator of negation = -
brush 2 dogs = 2D
then the sentence
Winston can milk ten cows and feed ten chickens, but he cannot brush two dogs before he has to go to school
written in logical symbols:
C)
the sentence 'before he has to go to school' is not a considered statement because the phrase does not have logical operator, like and, or, not
