Need answers for 70-75

adoni [48]

Answer:

70. 0

71. -54

72. 12

73. 86

74. 59

Step-by-step explanation:

To evaluate an expression, substitute specific values for the variables and simplify using Order of Operations.

70. c-3d becomes

$(1)-3(\frac{1}{3}) = 1-(\frac{3}{3}) = 1-1 = 0$

71. $x+x^3-4x^4$ becomes

$2+2^3-4(2)^4 = 2+8-4(16) = 2+8-64=10-64=-54$

72. $5a+3a^2$ becomes

$5(-3)+3(-3)^2 = -15 +3(9) = -15 + 27 = 12$

73. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(30)+32=\frac{270}{5}+32 = 54+32 = 86$

74. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(15)+32=\frac{135}{5}+32 = 27+32 = 59$

Plutonium-240 decays according to the function where Q represents the quantity remaining after t years and k is the decay consta

taurus [48]

Note: a radioactive decay constant is always negative.

time = [natural log(ending amount / beginning amount)] / k
time = ln (20 / 24) / -.00011
time = ln (5/6) / -.00011
time = -.018232155683 / -.00011
time = 165.7468698455 
time = 165.75 years

A picture frame is shaped like a rectangle whose perimeter is 196 cm. The length is 6 times long as the width

lbvjy [14]

L=length W=width
perimeter=2Lx2W
196=2L+2W

Length can be written as 6W because it is 6 times the width. We then substitute this in so all the terms are the same

196=2(6W)+2W
196=12W+2W
196=14W
W=14cm
L= (14x6) 84cm
