i really need help i dont understand geometry please answer both
Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )
100 × tan35° = opp , that is
opp ≈ 100 × 0.7002 = 70.02
Thus height of tree = 70.02 + 5 = 75.02 ft
--------------------------------------------------------------------
Using the tangent ratio in the right triangle on the right.
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )
rope × tan40° = 25.17 ( divide both sides by tan40° )
rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

Answer:
6
Step-by-step explanation:
Step-by-step explanation:
Answer:-[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]
We need the value of x. So, we will break the brackets first.
[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]
[tex]\bf{2x + 20 = 8x - 4}[/tex] [ Distributive Property]
[tex]\bf{2x -8x = -20 - 4}[/tex] [ Brought x to one side and signs interchange]
[tex]\bf{-6x = -24}[/tex]
[tex]\bf{x = \dfrac{24}{6}}[/tex]
[tex]\bf{x = 4}[/tex]

The equation 3x =y models the relationship between jellyfish, and sea turtles such that the ratio of their numbers remain constant.
What is ratio?Ratio is the relationship between two numbers given by a quotient
If the ratio of two numbers x and y is x/y then the fraction x/y gives that what parts x is of y .
Given that there are 4 sea turtle and 12 jellyfish in the sea when Alex counted the number.
Ratio of number of sea turtle to number of jellyfish = 4/12 = 1/3
Let at any time the number of sea turtles be x and number of jellyfish be y
Then ratio of number of sea turtles to jellyfish = x / y
Given that this ratio remained constant during the remainder of his dive,
∴ x/y = 1/3
Cross multiply
⇒ 3x = y
The equation that models the relationship between jellyfish, and sea turtles is 3x =y

-5a + 15/2a - 25 = 53.2 + 21.8
Answer:
a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8
add like terms on both sides: 2.5a - 25 = 75
add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
Answer:
a = 40
Step-by-step explanation:
-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable
-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms
-10/2a + 15/2a = 100: CLM again
5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable
a = 40

What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2,1)?
Answer:
y=5x+11
Step-by-step explanation:
You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.
First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.
Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.
y-(1)=5(x+2)
y-1=5x+10
y=5x+11
Check:
(1)=5(-2)+11
1=-10+11

Caelan is saving to buy a vacation home. He inherits some money from a wealthy uncle, then combines this with the $ 24162 he has already saved and doubles the total in a lucky investment. He ends up with $ 146012 , just enough to buy a cabin on the lake. How much did he inherit?
Answer:
The amount inherited is $48,844
Step-by-step explanation:
Here, we want to know the amount of money inherited by Caelan.
Let the amount be $x
From the question, the amount inherited was combined with 24,162 and doubled in an investment to give 146,012
Thus, the amount before the lucky investment will be;
x + 24,162
Thus , after doubling, the amount becomes;
2(x + 24,162)
and this equals 146,012
2(x + 24,162) = 146,012
divide both sides by 2
x + 24,162 = 73,006
x = 73,006 - 24,162
x = $48,844
