Answer:

  • h -102 = 331
  • h = 433

Step-by-step explanation:

Using the problem statement as the basis for the equation, we can write ...

  h -102 = 331

__

Using the diagram as the basis for the equation, we could write it as ...

  h = 331 +102

__

The original height of the helicopter was 433 m.

What is the reciprocal of each mixed number? Drag and drop the answer into the box to match each number.
Gnoma [55]
Hi there!! 

First, we are going to find the improper fraction of each mixed number. 

10 1/3 >>>>> 10*3+1=31 31/3

2 2/3 >>>>> 2*3+2=8.      8/3 

5 1/3 >>>>>> 5*3+1 = 16.  16/3 

TO find the reciprocal, we switch the numerator with the denominator. 

31/3 changes to 3/31, 8/3 changes to 3/8, and finally 16/3 changes to 3/16. 


Your answer is: 

3/31
3/8
3/16

Hope this helps! Let me know if you have any questions:)

We have two unknowns: x and y. Now, we have to formulate 2 equations. The first would come from the use of the given ratio:

We use the distance formula to find the distance between coordinates:

3/4 = √[(x-4)²+(y-1)²] / √[(4-12)²+(1-5)²]
√[(x-4)²+(y-1)²]  = 3√5
(x-4)²+(y-1)² = 45
x² - 8x + 16 + y² - 2y + 1 = 45
x² - 8x + y² - 2y = 28  --> eqn 1

The second equation must come from the equation of a line:
y = mx +b
m = (5-1)/(12-4) = 1/2

Substitute y=5 and x=12 for point (12,5)
5 = (1/2)(12) + b
b = -1

So, the second equation is

y = 1/2x -1 or x = 2 + 2y --> eqn 2

Solving the equations simultaneously:
(2 + 2y)² - 8(2 + 2y) + y² - 2y = 28 
Solving for y, 
y = -2
x = 2+2(-2) = -2

Therefore, the coordinates of point A is (-2,-2).

Answer:

Angles and XWY and STR

Step-by-step explanation:

These two angels are alternate exterior angels because:

- They are on different sides of the transversal (the line intersecting the two parallel lines)

- They have the same angle measure

- They are exterior, meaning they are on the outside, not inside (interior)

Hope this helps!!! :)
