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.

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.

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.

first term: 5x-5y

common difference: -x/2 + y

The common difference is d = -0.5x + y and the first term is 5x-5y

The nth term of the geometric progression is expressed as:

[tex]T_n=a+(n-1)d[/tex]

where;

The 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

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.

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

Answer: 2

Step-by-step explanation:

Each cup of tea costs $10.

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.

-3d < 15 (divide both sides by -3)

d > -5 (this is your answer, when you divide by a negative number in an inequality, the sign flips the other way)

Answer:

a=2

b=0

c=12

Step-by-step explanation:

The standard form of a quadratic equation is ax²+bx+c=0

Here's the given equation:

2x²+12=0

You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.

The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2

12 has no variable, so that means it'll be c in the equation.

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
