*Laila is not wearing tennis shoes.
*It is not the case that Laila is wearing tennis shoes.
(b)
*Jassim is in Germany
Step-by-step explanation:
honestly in my opinion that’s my answer. to be honest either could be wrong but I’m fairly confident in part a but b I’m sorta confident.
(a) what you need to do is focus on the word negations and then you’ll see easily what the answers are. and that’s how I got the answers I got.
meaning of negations : the contradiction or denial of something
(b) so on part b your looking for the conclusion of the sentence and as the sentence explains “If Jassim’s spouse is happy, then Jassim is in Germany.” and for me I came to the conclusion of that answer.

[tex]\boxed{\boxed{C) Center:(0,0);\: Vertices:(-10,0),(10,0);\:Foci:(-6,0),(0,6)}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:conic geometryalgebraPEMDASgiven:[tex] \frac{ {x}^{2} }{100} + \frac{ {y}^{2} }{64} = 1[/tex]to find:centerverticesfocitips and formulas:[tex] \sf ellipse \:equation : \\ \tt\frac{( {x}^{2} - h)}{ {a}^{2} } + \frac{( {y}^{2} - k)}{ {b}^{2} } = 1[/tex][tex] \sf c(h,k)[/tex][tex] \sf v(h \pm a,k)[/tex][tex]\sf F(h\pm c,k)[/tex][tex] \sf c = \sqrt{ {a}^{2} - {b}^{2} } [/tex]let's solve:[tex] \sf rewrite \:the \: given \: equation \: as \: ellipse \: equation \\ \tt \frac{ {(x - 0)}^{2} }{100} + \frac{ ({y - 0)}^{2} }{64} = 1[/tex]since we can see that h and k is 0
therefore
c(0,0)
[tex] \sf vertices :( h \pm a,k)[/tex]
given:a²=100
let's find a
a=√100
a=10
therefore
vertices:(0±10,0)

=(10,0) and (-10,0)
[tex] \sf foci : (h \pm c,k)[/tex]
[tex] \tt c = \sqrt{ {a}^{2} - {b}^{2} } [/tex]
[tex] \sf \: c = \sqrt{ {10}^{2} - {8}^{2} } \\ \sf \: c = \sqrt{(10 + 8)(10 - 8)} \\ \sf c = \sqrt{(18)(2)} \\ \sf c = \sqrt{36} \\ \tt c = 6 [/tex]

The aquarium opened at 8.00 am . In the first hour 140 people purchased admission tickets . In the second hour 25 % more people purchased admission tickets than the first hour . Each ticket cost 15.25 . What was the total amount of money paid for all the tickets purchased in the first two hours please help
Answers
Answer:
Total income= $4,083.75
Step-by-step explanation:
First, we need to calculate the total number of people that enter the aquarium in the first two hours.
1st hour= 140
2nd hour= 140*1.25= 175
Total number of people= 315
Now, we can determine the total amount of money earned:
Each ticket cost 15.25.
Total income= 315*15.25
Total income= $4,083.75
