If a triangle has 2 sides of 8 and 11 what could the third side be

Answers

Answer:

Any value between 3 and 19 may be the measure of third side.

Step-by-step explanation:

If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.

1). a + b > c

2). b + c > a

3). a + c > b

If a = 8, b = 11,

1). 8 + 11 > c

   c < 19

2). 11 + c > 8

    c > 8 - 11

    c > (-3)

3). 8 + c > 11

    c > 11 - 8

    c > 3

Therefore, by combining the given inequalities,

3 < c < 19

Any value between 3 and 19 may be the measure of third side.

18 bottles of water cost $9. How much does it cost for one bottle of water? How much bottles can you buy with $6?​

Answers

Answer:

Water cost 2$ you can buy 3 water bottles with 6$

Step-by-step

I did myself

Answer:

one bottle of water is 0.5 dollars. You can buy three bottles of water for $6

Step-by-step explanation:

since 9 divided by 18= 0.5, this is how it goes

18 bottles broken up into sections of one (one bottle in each section)

so you have to break up the dollars into cents to put an equal amount with each bottle. So you get 100 pennies for each dollar. There's only 9 dollars, so you split the pennies (that you broke from the 9 dollars) and put one in each section (each section still has one bottle) so each bottle with get one more penny with every round. The bottles take turns getting pennies. After you do all of them you will get 0.5 dollars for each bottle so that's how much the bottles cost.

The bottles cost 0.5 dollars.

Now we do this with 6 dollars instead of 9. You now know that each bottle cost 0.5 dollars so you have to do this

0.5 x 6 which = 3.

You can buy 3 bottles with $6.

I hope this helps!

7. The two equations have different solution steps. Do they have the same solution?

Step-by-step explanation:

Both of these equations have the same solution, just different steps.

To solve Ravi's equation, first we use the distributive property.

2(x+14) = 40

Multiply 2 by x and 14

2x + 28 = 40

Subtract 28 from both sides.

2x + 28 - 28 = 40 - 28

2x = 12

Divide by 2 on both sides.

2x/2 = x

12/2 = 6

so x = 6.

Fran's equation is the same equation as Ravi's second step.

Her equation of 2x + 28 = 40 is Ravi's after distributing 2.

Answer:

2(x+14)=40

2(x+14)=40

÷2         ÷2

x+14=20

 -14  -14

x=6

2x+28=40

2x=12

x=6

Select all equations that have graphs with the same y-intercept.

y = 3x - 8
y = 3x - 9
y = 3x + 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8

Answers

y=3x-8
y=5x-8
y=2x-8
y=1/3x-8
the y intercept is the b in y=mx+b and all of these have -8 as the y int

The equations that have graphs with the same y-intercept are:

y = 3x - 8y = 5x - 8y = 2x - 8y = (1/3)x - 8

To determine which equations have graphs with the same y-intercept, we need to look for equations that have the same constant term when written in the form y = mx + b, where m represents the slope and b represents the y-intercept.

The y-intercept is the value of y when x is equal to 0. In other words, it is the point where the graph intersects the y-axis.

Let's compare the equations and their constant terms:

y = 3x - 8 (Constant term: -8)

y = 3x - 9 (Constant term: -9)

y = 3x + 8 (Constant term: 8)

y = 5x - 8 (Constant term: -8)

y = 2x - 8 (Constant term: -8)

y = (1/3)x - 8 (Constant term: -8)

From the comparison, we can see that the equations y = 3x - 8, y = 5x - 8, y = 2x - 8, and y = (1/3)x - 8 all have the same constant term of -8. This means that their graphs will have the same y-intercept, which is -8.

Therefore, the equations that have graphs with the same y-intercept are:

y = 3x - 8

y = 5x - 8

y = 2x - 8

y = (1/3)x - 8

Brainly annie has 2 bags of apples and 5 single apples eva has 1 bag of apples and 11 single apples they have the same amount of apples how many apples so they have in total

Answers

Answer:

34 apples

Step-by-step explanation:

To answer: try setting up each of the equations for Annie and Eva.

Annie: 2(bag) + 5

Eva: 1(bag) + 11

Those two equations equal each other. So set that up:

2(bag) + 5 = 1(bag) + 11

Now solve for the size of the bag.

2(bag) - 1(bag) = 11 - 5

1(bag) = 6 apples

Now substitute 6 back into either equation to determine number of apples.

Annie: 2(6) + 5 = 12+5=17

They each have 17, so there are 34 apples in total.

A company rents out 16 food booths and 23 game booths at the county fair. The fee for a food booth is $100 plus $9 per day. The fee for a game booth is $95 plus $5 per dat. The fair lasts for d days, and all the booths are rented for the entire time. What is the simplified expression for the amount, in dollars, that the company is paid.

Answers

Answer:

3785 + 259d

Step-by-step explanation:

cost of food booths = 16 * (100 + 9d) = 1600 + 144d

cost of game booths = 23 * (95 + 5d) = 2185 + 115d

total = 1600 + 2185 + 144d + 115d = 3785 + 259d

Step-by-step explanation:

First convert 4.2m to cm

100cm = 1m

x = 4.2m

x = 4.2 * 100

x = 420cm

70cm to 420cm = 70/420

70/420 = 7/42

7/42 = 1/6

Hence 70 cm as a fraction of 4.2 m is 1/6
