Answer:

[tex]d=\sqrt{274}[/tex]

Step-by-step explanation:

[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(6-(-9))^2+(-4-3)^2} \\d= \sqrt{(15)^2+(-7)^2} \\d= \sqrt{225+49} \\d= \sqrt{274}[/tex]

Answer:3

Step-by-step explanation:

Answer:

Step-by-step explanation:

x - 4y = 4

-4y = -x + 4

y = 1/4x - 1

y + 1 = 1/4(x + 8)

y + 1 = 1/4x + 2

y = 1/4x + 1

Answer:

E) |g-540|

Step-by-step explanation:

E) |g-540|

If it weighed a bit over, say 545, you would get |545-540|=|5|=5

If it weight a little under, say 535, you would get |535-540|=|-5|=5

Either way, it tells you how far away from 540 the package is in grams from the desired weight.

Answer:

6

Step-by-step explanation:

Because 5.8 is closer to 6 than it is to 5.

6

If you want to round to the nearest whole number, the answer would be 6. Remember, if the number right after the decimal is higher than 5, you want to round up, if the number is lower that 5, you will want to round down. I hope this helped!! :)

Answer:

"If the game is a team sport, the game is field hockey"

Truth value → True

Step-by-step explanation:

The conditional statement is,

"If the game is field hockey, then the game is a team sport"

There are two statements,

Statement p → The game is a field hockey.

Statement q → Game is a team sport.

For the converse statement,

If p then q (q → p)

So the converse will be,

"If the game is a team sport, the game is field hockey"

Since, both the statements p and q are TRUE, truth value will be TRUE.

(Converse is false only when q is false and p is true)

Answer: Another way of looking at this problem, is that Laura will "gain" 2 miles on Tony in 1 hour. Why? She is going 7 miles in 1 hour, while Tony is only going 5. 7-5 = 2.

However, Tony is only .5 miles ahead and the question asks how long will it take for her to catch up, not to overtake him or beat him in some race.

I would make a simple ratio here. If in 1 hour/she beats him by 2 miles, x hours/she beats him by .5 miles.  

Another way to write that is 1/2 = x/.5

If you solve the equation, you get (by cross-multiplication) 2x = .5, x = .5/2, x =1/4.

Now, we are dealing with hours, so since there are 60 minutes in one hour, multiple the value you obtain for x by 60 minutes (60*1/4) = 15 minutes.  

Therefore, it will take Laura 1/4 of an hour, or 15 minutes, in order to catch up with Tony

Answer:

80%

Step-by-step explanation:

Since we're excluding hydrogen and helium, we are looking for the % of nitrogen and oxygen.

From the graph, we can see that we found 75% oxygen (blue).

We can also see that of nitrogen, green, we found 5%.

We simply need to add these two together.

75% + 5% = 80%

Answer: 80%

3(2y-7)=

Distribute

Step-by-step explanation:

3(2y-7) = 6y-21

y = 21/6

y = 3

Answer:

10 units

Step-by-step explanation:

[tex]\boxed{distance = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }}[/tex]

Using the distance formula above,

distance between the 2 points

[tex] = \sqrt{[0 - ( - 8)]^{2} + (7 - 1)^{2} } \\ = \sqrt{(0 + 8)^{2} + 6^{2} } \\ = \sqrt{ {8}^{2} + 36} \\ = \sqrt{64 + 36} \\ = \sqrt{100} \\ = 10 \: units[/tex]

angle 2 = 103° ( vertically opposite angles )

angle 1 = angle 3

103° + 103° + 2 ( angle 1 ) = 360° ( angle 1 = angle 3 )

or, 206° + 2 (angle 1) = 360°

or, 2(angle 1) = 360 - 206

or, 2(angle 1) = 154°

or, angle 1 = 154/2 = 77°

angle 2 = 103° (vertically opposite angles)

angle 1 = angle 3 = 77° (vertically opposite angles)

Answer:

$1802.47; $1784.47; $1733.20; $2121.83; $2224.59

Step-by-step explanation:

Variable x = answer

Part 1:

1023.49 + 778.98 = x

$1802.47 = x

Part 2:

1023.49 + 778.98 - 18.00 = x

1802.47 - 18.00 = x

$1784.47 = x

Part 3:

1023.49 + 778.98 - 18.00 - 51.27 = x

1802.47 - 18.00 - 51.27 = x

1784.47 - 51.27 = x

$1733.20 = x

Part 4:

1023.49 + 778.98 - 18.00 - 51.27 + 388.63 = x

1802.47 - 18.00 - 51.27 + 388.63 = x

1784.47 - 51.27 + 388.63 = x

1733.20 + 388.63 = x

$2121.83 = x

Part 5:

1023.49 + 777.98 - 18.00 - 51.27 + 388.63 + 102.76 = x

1802.47 - 18.00 - 51.27 + 388.63 + 102.76 = x

1784.47 - 51.27 + 388.63 + 102.76 = x

1733.20 + 388.63 + 102.76 = x

2121.83 + 102.76 = x

$2224.59 = x

A simpler way to do this is by using the last number and adding or subtracting to that. I showed it this way to give you a better understanding.

Answer:

Step-by-step explanation:

The graph starts at x = - 3 and ends x = 2. For all x between -3 and 2, there points on the graph. Hence the domain, in interval notation, is written as

[-3 , 2]

We have closed circles at x = - 3 and x = 2 because -3 and 2 are included in the domain which is indicated by the closed brackets at x = - 3 and x = 2.

The range is the set of possible output values, which are shown on the y-axis.

This is why our graph goes from (-3,8) to (2,3)

Answer:

[tex]9[/tex]

Step-by-step explanation:

So we have the expression:

[tex]\sqrt{6-25t}[/tex]

And we want to find the value of the expression when t is -3.

So, substitute -3 for t:

[tex]\sqrt{6-25(-3)}[/tex]

Multiply:

[tex]=\sqrt{6+75}[/tex]

Add:

[tex]=\sqrt{81}[/tex]

Evaluate:

[tex]=9[/tex]

So, our answer is 9.

And we're done!
