Finite Math Examples. Popular Problems · Finite Math. Find the Distance Between Two Points (7,2) , (-1,4).

Answer:

The distance is Sqrt(130) or in decimal form, 11.01...

Step-by-step explanation:

The distance formula states that you need to do sqrt((a-x)^2+(b-y)^2)). In this scenario (x,y)(a,b)= (1,7)(-2,-4) So we just fill in that formula. (-2-1)=-3^2=9; (-4-7)=11^2=121; 121+9=130. The distance is therefore Sqrt(130) or in decimal form, 11.01...

Answer:

A 12 pound baby is equivalent to 5.4kg, while a watermelon weighs 7.5kg, which is obviously larger than 5.4, so the watermelon weights more.

Step-by-step explanation:

To start off, we should convert the numbers in the same units. The question has told us that 1 pound is around 0.45kg. So let's do 12  * 0.45 which gives us 5.4kg. We already know that a watermelon weighs 7.5 kilograms, so from this we know that the watermelon weighs more.

Answer:

Howard works 7x+7 hours in a week

Step-by-step explanation:

Equations

Ron and Howard work at Amazon.

Ron works x hours each week for 7 days. This means he works 7x hours a week.

Howard works one more hour per day than Ron, thus he works x+1 hours per day. This means he works 7(x+1)=7x+7 hours a week.

Howard works 7x+7 hours in a week

Answer:

10 teeth must go on the driven gear

Step-by-step explanation:

Let the number of teeth be x

In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that

17:5 = 34:x

[tex]\frac{17}{5} = \frac{34}{x}\\Now\ let\ us\ cross-multiply\\17 \times x = 5 \times 34\\17x = 170\\dividing\ both\ sides\ by\ 17 \\x = \frac{170}{17} \\x = 10[/tex]

∴ 10 teeth must go on the driven gear

hence ratio = 34:10

Question??

Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?

Explanation;

Since this is an AND situation, we MULTIPLY the probabilities.

Answer/Explanation:

First light green:

Second light green:

Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent

Answer: The answer would be x = 19/3, 5/3

Step-by-step explanation:

Since we are finding the x intercepts, we must set the equation to equate 0. So:

0 = 3 |x-4| - 7

Then, we want to simplify the right side so it is just the absolute value, so lets start by adding 7 to both sides.

0 = 3 |x-4| - 7

+7              +7

7= 3 |x-4|

Now we divide both sides by 3.

7= 3 |x-4|

3        3

7/3 = |x-4|

Now, due to the properties of absolute value, we must solve this twice, since absolute value always leads to a positive value, we want to set up one equation where 7/3 is positive and one where it is negative.

7/3 = x-4        -7/3 = x-4

add 4 to both sides

7/3 = x-4        -7/3 = x-4

+4      +4          +4     +4

Then, you get your two x values

x= 6.333... or 19/3 AND x = 1.66666 or 5/3

[tex]175.50 \times 2 = 351.00[/tex]

He needs to pay $351.00 for 6 pairs of shoes.

Step-by-step explanation:

let's use ratio

3/ 175.5. as 6/X

cross multiply and solve for X

[tex] \frac{3 }{175.5} = \frac{6}{x} [/tex]

3X = 1053......divine both sides by 3 to solve for X

X = 351.

James would pay $351 for 6 pairs of shoes.

or you should have just multiply 175.5 by 2 because 6 pairs us the double of 3.

Answer:

Answer is D (2 drinks and 5 hotdog's)

Step-by-step explanation: 1st answer is over as it is $19.25 for only the hotdogs. 2nd is $18.50 which is a little over. 3rd one is $22.25. And the forth one is $16.75 which is perfect because he cant buy anything else with the remainder of his money.

You can use trial and error for 3 drinks and 2 drinks and can see how many hot dogs are available for Jacob to buy in $18 budget.

Jacob, with $18 dollars for food, under given conditions, can buy:

Option D: 2 drinks and 5 hot dogs.

This can be modeled by mathematical expression with use of variables, and inequality.

Suppose that you can by [tex]x[/tex] drinks and [tex]y[/tex] hot dogs, then their amount should not exceed $18 and they should try to use that $18 as much as they can.

Since 1 drink costs $1.5 and 1 hot dog costs $2.75, thus,

[tex]1.5x + 2.75y \leq18[/tex]

For 2 drinks:

Since x = amount of drinks = 2, thus from the obtained inequality, we have:

[tex]1.5x + 2.75y \leq 18\\1.5 \times 2 + 2.75y \leq 18\\2.75y \leq 18 - 3\\y \leq \dfrac{15}{2.75}\\\\y \leq 5.555...\\y = 5[/tex]

We took y = 5 since it is closest integer less than 5.55... since we cannot buy drink or hot dog in decimal points generally and cannot spend more than $18

Thus, if Jacob buys 2 drinks, then he can by 5 hot dogs at max.

For 3 drinks:

Since drinks' amount increased, then hot dogs amount will have to decrease to keep them together under $18. And since in 2 drinks Jacob could by 5 hot dogs, thus, now he will have to buy less than 5 hot dogs, which are not given in options.

Thus,

Jacob, with $18 dollars for food, under given conditions, can buy:

Option D: 2 drinks and 5 hot dogs.

Answer:

(176, 193)

Step-by-step explanation:

Well you forgot to put in the choices, but:

The difference between the numbers is 17. Let's call the smaller number x and the bigger one y

(x + y) = 369

y = x + 17

(x + (x + 17)) = 369

2x + 17 = 369

2x = 352

x = 176

y = x + 17 = 193

Answer:

The slope is 25 and the y-intercept is 100

Step-by-step explanation:

With linear equations (y = mx + b), m is always the slope, which, in this case, is 25. It could also be written as [tex]\frac{25}{1}[/tex], although it's not necessary here

B is always the y-intercept, which is 100 here

(3, -2)

Step-by-step explanation:

both of the equations are equal to y, which means they are equal to each other.

So you write them as equation(1) = equation(2)

and solve for x.

Next substitute the value of x to any of the equations and find y. And that is how I got (3 , -2)
