it's approximately 90 seconds for the average person to brush his or her teeth if a person brushes their teeth twice daily approximately how much time does one person spend brushing their teeth in a year
Answer:
65700 seconds a year for 2 times a day
Step-by-step explanation:
The required time an average individual spent time on brushing their teeth in a year is 65700 seconds.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more undertandable is called simplifying and the process is called simplification.
Here,
it's approximately 90 seconds for the average person to brush his or her teeth and a person brushes their teeth twice daily.
1 year = 365 days
And in a person spends 90 + 90 seconds brushing their teeth,
Time spent on brushing teeth in 1 year = 180 × 365 = 65700 seconds.
Thus, the required time an average individual spent time on brushing their teeth in a year is 65700 seconds.

Answer:
x = 5 cm.
Step-by-step explanation:
Since this is a right triangle, we can just use Pythagorean Theorem to find the hypotenuse:
a² + b² = c²
3² + 4² = x²
9 + 16 = x²
25 = x²
5 = x
Therefore, x is 5 cm.

URGENT!!! PLEASE HELP!! two cars leave at the same time from two cities that are 374 miles apart and travel towards each other. Car 1 travels 50 mph and Car 2 travels 60mph. How long do they travel before they meet?
Answer:
3 hours and 40 minutes I think
Step-by-step explanation:
Answer:
3 hours and 40 mins
Step-by-step explanation
First, you check 3 hours times 50 miles and 3 hours times 60 miles to get how close they are. 3x50=150, and 3x60=180. 150+180=330. Then you multiply 4/6 or 2/3 by 5 and 6 then add them (because 40 mins is 2/3 of an hour) 50x2/3/2=100/3 and 60x2/3=120/3=40. 40+50/3=73 1/3. 73 1/3+330= 3 hours and 40 mins.

A bank offers an annual simple interest rate of 6% on home improvement loans. How much would Tobias OWE IN ALL if he BORROWED $12,000 over a period of 3 years?
Answer: $14160
Step-by-step explanation:
Simple interest would be calculated as:
= PRT/100
where,
P = Principal = $12000
R = Rate = 6%
T = Time = 3 years
Simple interest = ($12000 × 6 × 3)/100
= $216000/100
= $2160
The amount that Tobias owe in all would be:
= $12000 + $2160
= $14160
Billy has a gift card with a $145 balance. He buys several video games that cost $45 each. After the purchases, his gift card balance is $10. Enter an equation to help find out how many video games Billy bought.
Answer:
Equation is 145 - 45 x = 10.
Billy bought 3 video games.
Step-by-step explanation:
As given,
Total Balance in the gift card = $145
The cost of each video game = $45
After purchasing , Balance in Gift card = $10
Now,
Let Total number of video games Billy purchase = x
⇒Cost for video game = 45x
Now,
As we know ,
Total Balance - Purchased Item = Balance left
⇒ 145 - 45 x = 10
∴ The equation is 145 - 45 x = 10
Now,
145 - 10 = 45x
⇒135 = 45x
⇒ x = [tex]\frac{135}{45}[/tex] = 3
∴ we get
Billy bought 3 video games

For this item, enter the answer in the space provided. A concession stand at school is selling cups of tea and hot chocolate after school. A student can buy 3 cups of tea and1 cup of hot chocolate for $12.00 or 1 cup of tea and 2 cups of hot chocolate for $14.00. Each cup of tea costs $______
Answer: 2
Step-by-step explanation:
Each cup of tea costs $10.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let consider X = cups of tea and Y= cup of hot chocolate
Therefore, the system of equation is,
3x + y = 12
x + 2y = 14
Solving;
-2(3x + y = 12)
-6x - 2y = -24
x + 2y = 14
Now, add;
-5x = -10
y = 2
Now substitute;
x + 2y = 14
x + 2(2) = 14
x = 10
Each cup of tea costs $10.

Which expression matches the situation?
You went to the mall with $90.00. You bought three shirts that cost x dollars each.
How much money do
you have left after buying the shirts? Which one matches please help
Answer:
The expression that matches the situation is 90.00 - 3x ⇒ 1st answer
Step-by-step explanation:
Let us solve the question
∵ You went to the mall with $90.00
→ That means the total money with you = $90.00
∴ The total money = 90.00 dollars
∵ You bought three shirts that cost x dollars each
∴ The cost of a shirt = $x
∴ The number of shirts = 3
→ Find the total cost of the three shirts
∴ The cost of the shirts = 3 × x
∴ The cost of the shirts = 3x dollars
∵ The money left = the total money - the cost of the shirts
→ Substitute the value of total money and the cost of the shirts
∴ The amount of money left = 90.00 - 3x
∴ You have left with 90.00 - 3x dollars
∴ The expression matches the situation is 90.00 - 3x dollars
find the first term and the common difference of an arithmetic progression in which t5=3x-y and t11=5y
t5 refers to term 5 and t11 refers to term 11
first term: 5x-5y
common difference: -x/2 + y
The common difference is d = -0.5x + y and the first term is 5x-5y
Geometric progressionThe nth term of the geometric progression is expressed as:
[tex]T_n=a+(n-1)d[/tex]
where;
a is the first termr is the common ration is the number of termsThe fifth term of the sequence is expressed as:
[tex]T_5=a+4d=3x-y[/tex]
[tex]T_{11}=a+10d=3x-y[/tex]
Take the difference of the terms:
[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]
Get the first term:
a = 3x - y - 4(-0.5x+y)
a = 3x - y + 2x - 4y
a = 5x - 5y
Hence the common difference is d = -0.5x + y and the first term is 5x-5y
