A jet travels 1536 miles against a jetstream in 2 hours and 1916 miles with the jetstream in the same amount of time. What is the rate of the jet in still air and
what is the rate of the jetstream?

Answer:

x=72°

Step-by-step explanation:

We know angles around a point equals 360°

Therefore,

(2x-61)°+(x-11)°+3x°=360°

2x-61+x-11+3x=360°

Collect like terms,

2x+x+3x-61-11=360°

6x-72°=360⁰

Evaluate;

6x=360°+72°

6x=432°

Divide both sides by 6

x=72°

Answer:

x = 72°

Step-by-step explanation:

there is a total of 360 degrees in a circle

we know we can add the angle measures shown and set it equal to 360

3x + (x-11) + (2x-61) = 360

combine 'like terms':

6x + (-11) + (-61) = 360

6x + (-72) = 360

6x = 432

x = 72

Check:

[2(72)-61] + (72-11) + 3(72) should equal 360

(144-61) + 61 + 216 = 360

83 + 61 + 216 = 360

360 = 360

Answer:

-11.8

Step-by-step explanation:

Given:

-3.4 to 12.4        increased  (difference = 15.8)

12.4 to 20.4      decreased (difference = 8)

20.4 to 3.2        increased  (difference = 17.2)

To find:

Final temperature.

Solution:

As we noticed, this is a pattern of increase, decrease, increase... (and so on and so forth). From this alone, we have gotten the clue that the temperature is going to decrease. But here is the thing, How far will it decrease?

Use the difference of the starting result to find the ending result.

3.2 - 15

= -11.8

Therefore, the final temperature is -11.8.

Step-by-step explanation:

The length of the pool is 15 feet and the width is 23 feet.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

Let L be the length of the pool.

According to the given information, the width of the pool is (2L - 7) feet.

The perimeter of a rectangle is the sum of all four sides, so we can write the equation:

2L + 2(2L - 7) = 75

Simplifying this equation:

6L - 14 = 75

6L = 89 + 14

L = 89/6

L = 14.833 ≈ 15

So the length of the pool is 15 feet and the width is (2 × 15 - 7) = 23 feet.

Answers:

3x + 40 =64

4x - 6 =26

Step-by-step explanation:

So we are dealing with 2 complementary angles with both add up to 90 degrees. We can write an equation that shows this:

(3x+40) + (4x-6) = 90

Combine like terms

7x + 34 =90

Isolate x

7x = 56

x = 8

Now that we found x, all we have to do is substitute it in the equations:

3x + 40 = ?

3(8) +40 = ?

24+40 = ?

64 = ?

4x - 6 = ?

4(8) - 6 = ?

32 - 6 = ?

26 = ?

Answer:

3x+40= 66

4x-6= 26

Step-by-step explanation:

3x+40+4x-6=90˚ (because the square on the angle represents a 90˚)

Add 4x and 3x

Which is 7x

40 minus 6 is 34

The equation now looks like this:

7x+34=90˚

Subtract 34 on both sides:

7x=56

Divide 7 on both sides:

x=8

For 3x+40

Substitute x with 8

the equation now looks like this:

24+40 Which is 66

For 4x-6

4 times 8 is 32

32 minus 6 which is 26

Answer:

  x = 2

Step-by-step explanation:

When a transversal crosses parallel lines, it creates 8 angles. Pairs of angles that are in the same direction from the points of intersection are called "corresponding angles." Corresponding angles are congruent.

__

In the given diagram, the marked angles are both "southeast" of their respective points of intersection. That means they are corresponding angles, and have the same measure.

  (9x -7)° = (7x -3)°

  2x = 4 . . . . . . . . . . . divide by °, add 7-7x

  x = 2 . . . . . . . . . divide by 2

_____

Check

The measures of the angles are ...

  (9(2) -7)° = (18 -7)° = 11°

  (7(2) -3)° = (14 -3)° = 11° . . . . same as the first angle, as it should be

Answer:

BC < AC < AB

Step-by-step explanation:

In triangle smallest has the smallest opposite side and so on

first find ∠A = 180 - 59 - 79

= 42

∠A < ∠B < ∠C

Then ∠A opposite side is BC is less

so BC < AC < AB

Answer:

Flipped over x-axis, Stretched by 4 times in y values, 1 unit to the left, and 8 units down.

Step-by-step explanation:

Sign in front, outside of parentheses, if negative, represents a vertical flip.

Multiple proceeding is the amount of stretch (or compression if it is a value less than 1)

A positive value within the parentheses represents a shift to the left.

The c value of this function being negative shows a downward transition.

Answer:

x=4

Step-by-step explanation:

Four less than the product of a number and 8:

8x−4

is twice the sum of the number and 10, so

8x−4=2(x+10)

Simplify.

8x−4=2x+20

Add 4 to both sides, which is

8x=2x+24

Subtract 2x from both sides:

6x=24

Divide 6 from both sides to isolate the x

x=4

-how I got 20

8x-4=2(x+10) x=8 so 8+10=18 18+2=20
