*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.

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
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

It’s for question 4
Answer:
$6,000
Step-by-step explanation:
We have to start by finding the conversation rate.
So, we can divide 9,600 by 8 to find how much the ratio is being multiplied by.
9,600 / 8 = 1200
Now that we know the conversion rate, we can multiply by five to find how much the expenses really cost, according to the ratio.
1200 * 5 = 6000
Their expenses this month are 6000

A ticket for a seat at a school play costs £2.95
There are 21 rows of seats.
There are 39 seats in each row.
The school will sell all the tickets.
Work out an estimate for the total money the school will get.
Answer:
Answer vary :
2.95(21 times 39) = $2,416.05
Step-by-step explanation:
honestly in my opinion that the answer. so we’re trying to find out how much money the school will earn.
if each seat cost 2.95 we need to find out how many seats are their?
-21 times 39 = 819
we multiplied the rows and seats find out how many seats their are and the answer is 819.
after you do that now we have to find out how much money they will earn from selling all 819 seats.
-819 times 2.95 = 2,416.05
we then multiplie all of the seats wich is 819 seats by 2.95 wich is the cost of one seat and got 2,416.05, and that’s the answer we’ve been looking for.
and that’s how I got my answer.
The total money school will get is £2416.05 on a play.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
A ticket for a seat at a school play costs £2.95
There are 21 rows of seats.
There are 39 seats in each row.
That means,
there are total 21 x 39 = 819 seats.
So, the total money the school will get,
= 819 x £2.95
= £2416.05
Therefore, school makes £2416.05 on a play.

Find the LCM.
11, 13
STEP 1: Define the LCM (least common multiple).
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all the numbers.
The LCM can be found by first writing each number as a product of prime factors.
The LCM must contain all the prime factors of each number.
STEP 2: Determine the prime factorization of each number.
Determine the prime factorization of 11.

What does it mean when a letter and number are together like this
Answer:
multiplication
Step-by-step explanation:
7 x e = f
Answer:
If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.
Step-by-step explanation:
We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.
Let me just give a number to e. Let's say e is 5
7e = f
We already know 7e is the same thing as 7 x e, so let's rewrite it
7 x e = f
We will change e to 5 and multiply the numbers together
7 x 5 = f
Now multiply 7 x 5
35 = f
If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)
But let's now take the original equation and assume f is 42
7e = f
Remember, 7e is 7 x e, so rewrite your equation
7 x e = f
Now we will change the f to 42
7 x e = 42
To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7
42÷7 = 6
That means e is 6. Now let's write the equation with changing e to 6
7 x 6 = 42
7 times 6 is 42, so we will multiply that
42 = 42
Now we have equal answers. Of course, 42 is equal to 42
Overall I'm trying to say 7e = f
I'll solve this again, so you won't have to go back up.
7e = f
7 x e = f
f = f
I hope this makes sense lol
