Answer: d. t = 4s + 230

Step-by-step explanation: In the first part of his regimen, Gustav sprints for a time of s seconds:

part 1: t₁ = s

In the second part, time is 150 more seconds than first part:

part 2: t₂ = s + 150

In part 3, time is twice the number as the first time:

part 3: t₃ = 2s

And in the last part, the regimen is of an 80 second sprint:

part 4: t₄ = 80

Th entire regimen has a total of seconds equal to

[tex]t=t_{1}+t_{2}+t_{3}+t_{4}[/tex]

t = s + s + 150 + 2s = 80

t = 4s + 230

The function which represents the total number of seconds suggest by the entire regimen is t = 4s + 230

Answer:

tina has 6 and Juan has 9

Step-by-step explanation:

4+2=6 and 6+3=9

Answer:

Step-by-step explanation:

For this problem, imagine the standard form, which is:

f(x) = ax² + bx + c = y

Using the table, and adding that y at the end, we can plug in and write out the following equations. (Writing it out is important):

f(-1) = a(-1)² + b(-1) + c = 14

f(0) = a(0)² + b(0) + c = 7

f(1) = a(1)² + b(1) + c = 4

f(2) = a(2)² + b(2) + c = 5

Now if this doesn't look familiar, it's actually a systems of equations using the a, b, and c elements as your three variables! If you simplify the equations:

f(-1) = a - b + c = 14

f(0) = c = 7

f(1) = a + b + c = 4

f(2) = 4a + 2b + c = 5

Something unique just happened. We have already defined what ' c ' is!

c = 7

Setting that aside, if you remove the f(x) portion of the equations, you're left with:

a - b + c = 14

a + b + c = 4

4a + 2b + c = 5

Using the two upper equations, if we add them together (you can do that as it doesn't change the values of the variables) you get:

2a + 2c = 18

Note: the ' b ' variables cancelled out in the addition [ b +  (-b) ]

If you further simplify the equation:

a + c = 9

Awesome. Now we already know that c = 7, so if you plug that into the equation:

a + 7 = 9

Solve for a. So then a = 2

Now that we know the following:

a = 2

c = 7

We can then use the equation:

a + b + c = 4

And solve for b!

2 + b + 7 = 4

Simplify.

b + 9 = 4

Simplify.

b = -5

Now at this point, since you know what a, b and c are, you can write the equation!

f(x) = 2x² - 5x + 7

You can confirm your work by putting any of the x values in the table through!

Answer:

Step-by-step explanation:

You do 5625 / 25 like this: For each step you multiply 25 by the highest number possible in the first 2 numbers. So if it was 27 / 9  you would find how many times 9 can fit into 27 but since the number 5625 is not one of the first 10 multiples of 25 you see the first 2 numbers and if you still can't divide you combine the next value. The top number is the answer.

Answer:

1/12

Step-by-step explanation:

Given the following mathematical expression;

[tex]\frac{\frac{1}{3}}{4}[/tex]

We would apply the law of indices for fractions.

1/3/(4) = 1/3 * 1/4 = 1/12

The solution is : 1/3 divided by 4 is 1/12.

Here, we have,

given that,

1/3 divided by 4

Given the following mathematical expression;

1/3 /  4

We would apply the law of indices for fractions.

1/3/(4)

= 1/3 * 1/4

=1/ 3*4

= 1/12

Hence, The solution is : 1/3 divided by 4 is 1/12.

Answer: 10x + 10y

8)

Step-by-step explanation:

Answer:

1/12

Step-by-step explanation:

first we have to find all the possibilities of getting a sum of 3 or less: 1+1 or 1+2 and we count the second combination 2 times because the numbers can be on either of the dices so we have a total of 3 possibilities. all the possible pairimg of dice are 6*6=36 because each dice has 6 sides and we can get either of them. so the probability would be the chance of getting a sum of 3 or less divided by all the diff combination which equals 3/36 or 1/12 which is roughly around 8.3%

Answer:

2/15

Step-by-step explanation:

Reduce the expression, if possible, by cancelling the common factors.

The equivalent value of the fraction is A = 2/15

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = p/q

when the value of p = 2/5

And , when the value of q = 3

On simplifying the equation , we get

A = ( 2/5 ) / 3

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) / 3

A = ( 2/5 ) / 3

A = ( 2/5 ) ( 1/3 )

On simplifying , we get

A = 2/15

A = 0.133333

Therefore , the value of A = 2/15 = 0.133333

Hence , the fraction is A = 2/15
