Which of the following could be the side measures of a right triangle?
A. 6 ft, 5 ft, 4 ft
B. 8 ft, 7 ft, 6 ft
C. 10 ft, 8 ft, 6 ft
D. 12 ft, 10 ft, 8 ft

Answers

Answer:

Step-by-step explanation:

First, let us try the first on:

sqrt (5^2+4^2)=sqrt 41 so it can't be A

Second one:

sqrt (6^2+7^2)=sqrt 85, no

Third one:

sqrt (8^2+6^2)=sqrt 100 = 10, so it is C

Answer:

Step-by-step explanation:

I will just say how to do C but it is the same for all of the other ones.

First I write a²+b²=c²

Then I put in the numbers and get 6²+8²=10²

After that I do the ² to all of them to get 36+64=100

Next I add 64 and 36, which equals 100

100=100

Answer: f(3) = g(3)

Step-by-step explanation:

ok so f and g are unknown numbers and 3 is equal to 3, since f and g are unknown they could be any number so that's why there the same.

Answer:

f(3) > g(3)

Step-by-step explanation:

add 3 into each equation.

f(x) = 4x^4 g(x) = 10 * 2^x

= =

f(3) = 4(3)^4 g(3) = 10 * 2³

Solve each equation.

f(3) = 4(3)^4 g(3) = 10 * 2^3

= =

f(3) = 12^4 g(3) = 20^3

= =

f(3) = 20,736 g(3) = 8,000

f(3) is greater than g(3)

f(3) > g(3)

NO WORK = NO CREDIT = REPORT

Thx for helpin <3 !

Answers

Answer:

The quotient would be 12.

Step-by-step explanation:

The first way to interpret it would be: 60 as the total amount of students, divided by 5 students per group which = 12 groups with 5 students in each.

The second way to interpret it would be: 60 as the total amount of students, divided into 5 groups which = 12 students in each group.

An amusement park charges $8 for parking in addition to $1.25 per ride ticket. Write an equation to represent the total cost to visit the amusement park, then find the number of rides a person can go on, if they have $30. Identify your variables.

Answers

Answer:

Amount of rides = (30 - 8)/1.25

Answer:

c = 8 + 1.25r

the unit used is dollars

r = the amount of ride tickets purchased

c = total cost

a person could could go on 17 rides with 30$

Step-by-step explanation:

To develop the equation:

1. first, you want your total cost on one side. That is c (c =)

2. second, you need to identify the variable that changes the cost in the equation. That would be the amount of ride tickets because it changes the total cost based on how many a person buys. (c = 1.25r)

3. third, you add the variable that never changes, which is the eight dollars for parking (c = 1.25r +8)

In order to solve for a specific amount of money, you plug in the amount in place of your total cost (c) variable. In this case, you would solve 30 = 8 + 1.25r

It would look something like this:

30 = 8 +1.25r

(subtract 8 from both sides)

22 = 1.25r

(divide each side by 1.25)

r = 17.6

(round down because you can't buy a ride ticket with only 60 cents)

and you're done!

hope that helps!

Answer:

Step-by-step explanation:

Given the lines shown here, what are two possible equations for this system of equations?

Answers

Answer:

Blue line: either y=1/4x+1, y=1/5x+1, or y=1/6x+1 (depending on how u see where it intercepts in the x-axis.

Black line: either y=1/4x-10, y=1/5x-10, or y=1/6x-10 (depending on how u see where it intercepts in the x-axis.

Step-by-step explanation:

Well because they don't have the numbers it's hard to tell. But they will have the same slope which makes them parallel. So the Y intecept for the blue line would be 1 if it's how it's shown. Then the slope would be one over 4,5 or 6. Then again I cannot see numbers there so... anyways, the equation for the blue line would be about y=1/5x+1. For the black line, I think it intercepts on the -10 for the Y. So if the slope is the same so that they can be parallel then it would be y=1/5x-10. (WARNING: This answer might change if they give you the numbers of the actual line. THIS IS JUST AN ESTIMATE!! THEY ARE POSSIBLE ONES!!!!!) But remember when lines are parallel they have the same slope but different Y-intercept! Hope this helped a bit... ask me if u have any questions.

cause y=mx+b (m is the slope which is rise over run) (b is the y-intercept)

Answers

Answer:

-4 is greater than -5.1.

Answer:

Step-by-step explanation:

In integers, it's almost backwards. If you are looking at a scale, -4 would be further up, or closer to zero than -5.1.

So, if you are looking at negative numbers, basically, the closer the number is to zero, the greater it is.
