Step-by-step explanation:

Let

f -----> Fred's age

n ----> Nathan's age

we know that

-----> equation A

equate the equations and solve for n

Find the value of f

therefore

Fred's age is 36 years old and Nathan's age is 9 years old

A surveyor wishes to determine the height of a mountain. At a given position he measures the angle of elevation to the top as 43
Usimov [2.4K]

Answer:

4,486.93 ft

Step-by-step explanation:

Let 'h' be the height of the mountain and 'x' be the horizontal distance between the first position measured and the top of the mountain.

Two right triangles can be modeled such that their tangent relationships yield:

tan(43.66) = \frac{h}{x}\\tan(38.2) = \frac{h}{x+1000}

Solving the linear system:

x= \frac{h}{tan(43.66)}\\x = \frac{h}{tan(38.2)} -1000\\\frac{h}{tan(43.66)}=\frac{h}{tan(38.2)} -1000\\1000 = 0.222869*h\\h=4,486.93\ ft

The mountain is 4,486.93 ft high.

Tammy earns money by mowing lawns for her neighbors. She currently has $75 and plans to mow lawns until she has at least $200 in
Flura [38]
The way I solved this problem was by subtracting 200-75 and getting 125. So he would need to mow 125 more lawns. To check your answer you can add 125+75 and get 200
I hope this helped :)

A firecracker shoots up from a hill 140 feet high, with an initial speed of 100 feet per second. Using the formula H(t) = −16t2
V125BC [204]
<span>H(t) = −16t^2 + vt + s

</span>
<span>H(t) = −16t^2 + 100t + 140

H(t) = 0 = </span><span>−16t^2 + 100t + 140

16t^2 - 100t -140 = 0

t = [100 +/- √ (100^2 -4(16)(-140) ) ] /(2(16))

t = 7.43 and t = - 1.18.

El que tiene sentido para la pregunta es t = 7.43 s.

Option B) 7 s (approximately)
