is -5.1 greater than -4?

Answers

Answer:

-4 is greater than -5.1.

Answer:

No

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.

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)

Georgia practiced for her dance recital for 3/4 of an hour on Monday, 3/8 of an hour on Tuesday, and 5/6 of an hour on Wednesday. How much longer did she practice on Monday than on Tuesday?

Answers

Answer:

The Answer is 22.5

Step-by-step explanation:

because 3/4 is 45 minutes.'

and 3/8 is 22.5 minutes.

45-22.5=22.5 minutes different.

ANSWER:
3/8 longer or 2 times longer or 22.5 minutes longer on Monday depending on the type of answer they want.

EXPLANATION:
3/8 longer or 2 times longer Explanation is:
Gotta find common denominator
Common denominator is 8
6/8 on Monday and 3/8 on Tuesday so difference of 3/8 or twice as long

22.5 Minutes Longer explanation is:
3/4 of an hour is 45 minutes (60/4=15x3=45) 3/8 of an hour is 7.5 minutes (60/8=7.5x3=22.5)
So 45-22.5= 22.5 minutes longer on Monday

the boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the model.

please help!!!

Answers

answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684

36m because 250 divided by 8=36m

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!

no, because the number line shows the arrow going backward, so now we know its subtraction, so you're going to count backward until you reach the number we are looking for so 7/8 minus 2/8 equals 5/8.
