Answer:
Any of these should work for ya :)
3/4 = 6/8 = 9/12 = 12/16
= 15/20 = 18/24 = 21/28 = 24/32
= 27/36 = 30/40 = 33/44 = 36/48
= 39/52 = 42/56 = 45/60 = 48/64
= 51/68 = 54/72 = 57/76 = 60/80
= 63/84 = 66/88 = 69/92 = 72/96
= 75/100 = 78/104 = 81/108 = 84/112
= 87/116 = 90/120 = 93/124 = 96/128
= 99/132 = 102/136 = 105/140 = 108/144
= 111/148 = 114/152 = 117/156 = 120/160
= 123/164 = 126/168 = 129/172 = 132/176
= 135/180 = 138/184 = 141/188 = 144/192
= 147/196 = 150/200 = 153/204 = 156/208
= 159/212 = 162/216 = 165/220 = 168/224
= 171/228 = 174/232 = 177/236 = 180/240
= 183/244 = 186/248 = 189/252 = 192/256
= 195/260 = 198/264 = 201/268 = 204/272
= 207/276 = 210/280 = 213/284 = 216/288
= 219/292 = 222/296 = 225/300 = 228/304
= 231/308 = 234/312 = 237/316 = 240/320
= 243/324 = 246/328 = 249/332 = 252/336
= 255/340 = 258/344 = 261/348 = 264/352
= 267/356 = 270/360 = 273/364 = 276/368
= 279/372 = 282/376 = 285/380 = 288/384
= 291/388 = 294/392 = 297/396 = 300/400

Situation:
A 33 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1473.
N = Noe
-kt
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
Find the substances half life, and days. Round your answer to the nearest 10th
Answer:
Half life = 4.7 days
Step-by-step explanation:
Formula to get the final amount of the substance after the time 't',
[tex]N_t=N_0e^{-kt}[/tex]
Here, [tex]N_t[/tex] = Final amount of the substance
[tex]N_0[/tex] = Initial amount
k = decay constant
t = Duration or time
Now by substituting the values in the formula,
[tex]N_t=N_0e^{-0.1473t}[/tex]
If [tex]N_t=\frac{1}{2}(N_0)[/tex] [For half life]
[tex]\frac{1}{2}(N_0)=N_0e^{-0.1473t}[/tex]
[tex]\frac{1}{2}=e^{-0.1473t}[/tex]
[tex]2=e^{0.1473t}[/tex]
ln(2) = [tex]\text{ln}(e^{0.1473t})[/tex]
0.69315 = 0.1473t
t = 4.71 days
t ≈ 4.7 days
Therefore, half life of the substance is 4.7 days.

( PLEASE HELP , TIMED ) A pet supply store sells three dog collars and two leashes for $59.75. The same pet store sells one dog collar and three leashes for $53.75. Find the cost of one dog collar and one leash.
Answer:
how can i help also comment me i wanna talk bc im lonely lol
Step-by-step explanation:
The cost of one dog collar and one dog leash are 10.25 dollars and 14.5 dollars respectively
How to form an equation?let
the cost of each dog collars = x
the cost of each leashes = y
Therefore,
3x + 2y = 59.75
x + 3y = 53.75
Hence,
3x + 2y = 59.75
3x + 9y = 161.25
7y = 101.5
y = 101.5 / 7
y = 14.5
Therefore,
x + 3y = 53.75
x + 3(14.5) = 53.75
x = 53.75 - 43.5
x = 10.25

How many terms are in the expression when simplified
Answer:
There are four (4) different terms
Step-by-step explanation:
Given;
2x + 3xy - (x + y) + 2
The terms are simplified as follows;
=2x + 3xy - (x + y) + 2
= 2x + 3xy - x - y + 2
collect like terms;
= 2x - x - y + 3xy + 2
= x - y + 3xy + 2
Thus, there are four (4) different terms in the simplified expression.
