Their are two triangle possible.

1 ) With hypotenuse of length x.

2) With hypotenuse of length 12.

Solution :

Case : 1 )

Using Pythagoras theorem :

x² = 7² + 12²

x = √( 7² + 12²)

x = √( 49 + 144 )

x = √(193)

x = 13.89

Case : 2 )

Using Pythagoras theorem :

x² + 7² = 12²

x² = 144 - 49

x = √95

x = 9.75

Hence, this is the required solution.

Answer:

25 = x

Step-by-step explanation:

The angles are vertical angles and vertical angles are equal

5x+15 = 6x -10

Subtract 5x from each side

5x-5x+15 = 6x-5x -10

15 = x - 10

Add 10 to each side

15+10 = x-10+10

25 = x

Answer:

4374

Step-by-step explanation:

Since, we are given table for x and y values

and table for average rate of changes

we can see the pattern of average rate of change

average rate of change for 5 to 6 is three times average rate of change for 4 to 5

but we have to find

average rate of change for 7 to 8

so, using same pattern

average rate of change for 6 to 7 is three times average rate of change for 5 to 6

average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)

so, we can plug value

average rate of change for 7 to 8 is 3*3*486

average rate of change for 7 to 8 is 4374

12x - 15xy

Step-by-step explanation:

3x(4-5y)

12x - 15xy

Answer:

The answer is y=12x ÷ 1+15x

Step-by-step explanation:

Simplify and keep y on the left side

Answer:

330=40x+50

Step-by-step explanation:

then you would -50 from both sides

280=40x

then you would divide both sides by 40 to isolate x

7=x

so that means it would take 7 weeks

Answer:

15 minutes

Step-by-step explanation:

The formula is

1/a + 1/b = 1/c to determine joint time  where a and b are the times alone and c is the time together

1/10 + 1/ 30 = 1/c

Multiply each side by 30c to clear the fractions

30c( 1/10 + 1/ 30) = 1/c * 30c

3c + c = 30

4c = 30

Divide by 4

4c/4 = 30/4

c = 7.5 minutes

This is the time for 50 pages

We want 100 pages, so multiply by 2

7.5 *2 = 15 minutes

Answer:

≈ 30 times

Step-by-step explanation:

The Cubs are projected to win 38 games next season and this is a 22.6% increase from past season.

Step 1 : Let's find 22.6% of 38.

= 8.588

Step 2 : Now, since we increased by this, we subtract.

38 - 8.588 = 29. 412

Of course you can't win only part of a game, so I'm going to say they won 30 times, because a little extra win never hurt anybody. :)

Answer:

Arc YX = 104°

Step-by-step explanation:

Arc YX + Arc YZ + Arc XZ = 360° (full circle = 360°)

Substitute

Arc YX + 110° + 146° = 360°

Arc YX + 256° = 360°

Arc YX = 360° - 256°

Arc YX = 104°

Answer:

x=12

Step-by-step explanation:

Both Angles together have a 180 degrees, set your formula up as

180=(10x-20)+(6x+8)

180=10x+6x-20+8

180+20-8=16x

192=16x

192/16=x

12=x

Answer:

x = 12

Step-by-step explanation:

The two angles form a straight line so they add to 180

10x-20 + 6x+8 = 180

Combine like terms

16x -12 = 180

Add 12 to each side

16x-12+12=180+12

16x = 192

Divide each side by 16

16x/16 =192/16

x = 12

Answer:

271 prints.

Step-by-step explanation:

So to answer the question, we need to first write a formula to find the answer.

We know that the starting price per month is 6.95 dollars.

The full price is 17.79 dollars.

So we can start this off by writing:

17.79=6.95

Now, every time Jim prints, he charges 0.04 dollars. This will add to the orginal cost, which is 6.95. And remember this isnt a single payment, but a payment that varies depending on the amount of paper, p. So we can write this as:

17.79=6.95+0.04p

6.95 wont ever change, hense why it doesnt have a variable. 0.04 however, varies depending on the amount of paper, and thats why we included the variable p.

These two values combined make 17.79, hense why it is on the opposite side of the equals sign.

So, now we need to find how many papers, p, were printed.

To find this, lets just take our equation, and solve for P like an ordinary problem:

17.79=6.95+0.04p

So first off, lets subtract the 6.95 from both sides, because that iscolates the 0.04p, which contains the variable.

Now we have:

10.84=0.04p

Now, we could divide both sides by 0.04.

But remember, the whole point of doing this is to make 0.04p into 1p.

So another way of doing this is multiplying the 0.04 by 25, since 0.04*25=1.

So lets multiply both sides by 25:

10.84*25 is 271.

Since 10*25 is 250

And

.84*25 is 21.

So now we know:

271=1p

So 271 is your answer!

Hope this helps!

The equation that can be used to find the number of prints, p, is $17.79 = $6.95 + $0.04p and Jim ordered 271 prints last month.

An equation is an expression that shows the relationship between two or more numbers and variables.

We can write an equation to represent the total cost that Jim was charged by the website for last month's prints, p to represent the number of prints he ordered:

Total cost = Monthly fee + Cost per print x Number of prints

Using the values given in the problem:

$17.79 = $6.95 + $0.04p

To solve for p, one side of the equation. First, we can subtract $6.95 from both sides:

$10.84 = $0.04p

Then, we can divide both sides by $0.04:

p = 271

Answer:

102 mph

Step-by-step explanation:

Eliana travels at an average speed of 50 mph for 60 miles.

Without stopping, Eliana then travels 130 miles in 2.5 hours.

We calculate the speed here

Speed = Distance in miles /Time in hours

Speed = 130 miles/2.5 hours

= 52 miles per hour

Hence, her average speed for the entire journey is calculated as:

50 mph + 52 mph

= 102 mph

Explanation:

A linear pair of angles is where they are both adjacent and supplementary.

Adjacent angles share a common line or ray. In this case, they share ray FE.

Supplementary angles add to 180. So they combine to a straight angle.

Answer:

Linear pair
