Answer:
35+125=160
She was 160 feet up when she began hang gliding
Answer:
160
Step-by-step explanation:
let A represent Aida hang gliding
we know that she was at 125 ft in the air
we know that she lost 35 ft in altitude
so the equation would be
125=A[-35]
what is boxed you change the opposite so the opposite of subtraction would be addition.
125=A[-35]
125=A+35
now we move the +35 under 125
if we add 125 and 35 it would give us 160 so the answer would be 160

12. Carla is lying on the ground between two trees in her backyard. She is 67 feet from the tree to her left. The angle of elevation from her eyes to the top of the tree on the left is 50°. Carla is 75 feet from the tree to her right and the angle of elevation from her eyes to the top of that tree is 36°. a. Determine the height of each tree to the nearest foot. Show your work. b. State which tree is taller, and by how much.
Answer:
the left tree is taller
Step-by-step explanation:
shown in work above :)
The first tree is taller than the second tree by 25.3 ft.
We have to use the trigonometric ratios and angle of elevation to obtain the height of each tree as follows;
Let the height of the first tree be h1 and the height of the second tree be h2.
For the first tree;
tan 50° = h1/67
h1 = 67 tan 50° = 79.8 ft
For the second tree;
tan 36° = h2/75
h2 = 75tan 36°
h2 = 54.5 ft
The first tree is taller than the second tree by 25.3 ft.

Step-by-step explanation:

1. Select all equations that are equivalent to (5x+6) over 2 =3-(4x + 12). A5+6= 3 - (4x + 12) (5x+6) B. 2 = -4x -9 c. x+3 = 3 – (4x + 12) (5x+6) = -4x + 15 2 E. 5x + 6 = -8x – 18
Answer:
Only option E is equivalent to [tex]5x+6=-8x-18[/tex].
Step-by-step explanation:
Given the expression
(5x+6) over 2 = 3-(4x + 12)
Let us simplify the expression
[tex]\frac{\left(5x+6\right)}{2}=3-\left(4x+12\right)[/tex]
Multiply both sides by 2
[tex]\frac{5x+6}{2}\cdot \:2=3\cdot \:2-\left(4x+12\right)\cdot \:2[/tex]
[tex]5x+6=6-\left(4x+12\right)\cdot \:2[/tex]
Expand -(4x + 12) = -4x - 12
[tex]5x+6=-8x-18[/tex]
Thus, option E is equivalent to [tex]5x+6=-8x-18[/tex].
Further solving
[tex]5x+6=-8x-18[/tex]
Add 8x from to both sides
[tex]5x+8x=-8x-24+8x[/tex]
Simplify
[tex]13x=-24[/tex]
Divide both sides
[tex]\frac{13x}{13}=\frac{-24}{13}[/tex]
Simplify
[tex]x=-\frac{24}{13}[/tex]
Thus, only option E is equivalent to [tex]5x+6=-8x-18[/tex].
Answer:
E. 5x + 6 = -8x – 18

A gift card stores data using a black, magnetic stripe on the back of the card. Find the width w of the stripe.
The width of w is 0.90 cm.
Find the length of the sides:The first step to solve this problem is to find how long is each side. About this, we know one side is 8 1/2 cm or 8.5 but the other side is not exactly given (4cm + w + 2/3 w). To determine the length of this size, use the area formula:
A = side a x side bSide b = A / side aSide b = 46.75 / 8.5Side b 5.5Find the length of w:The total length of the side - known side
5.5 - 4 = 1.5This means w + 2/3 w (0.66 w) is equal to 1.5
Find w:
w + 2/3 w = 1.5w + 0.66w = 1.51.66 w = 1.5w = 1.5/ 1.66w = 0.90 cmLearn more about width in: https://brainly.com/question/3133832
