Shaquil needs to borrow $400. the loan company charges him $80 in fees for the loan. shaquil calculates that the annual percenta
Mila [183]

The  term of shaquil's loan will be 29 days approximatly.

We have given that,

Principle amount (p) = $400

Rate (r)= 250% = 2.5

Interest = $80

t = time (in days) = t/365

<h3>What is the formula simple interest?</h3>

I=prt

r=\frac{I}{rt}

2.5 = \frac{80\times 365}{400\times t}

t= \frac{80\times 365}{400\times 2.5}

t=\frac{73}{2.5}\\ \\t=29.2

t = 29.2

t = 29 days

Therefore option (B) is correct.

Therefore the  term of shaquil's loan will be 29 days approximatly.

PLEASE HELP!!!! :(

The tangent of the angle gives the ratio of the height of the lighthouse to the boat's distance
.. tan(angle of depression) = (lighthouse height)/(boat distance)
Then the distance to the boat is
.. boat distance = (lighthouse height)/tan(angle of depression)

We want to find the difference between two distances, so
.. boat travel = (lighthouse height)*(1/tan(first angle) -1/(tan(second angle))
.. = (200 ft)*(1/tan(17°31') -1/tan(46°41'))
.. ≈ 445.10 ft

AHBAHAHAHAHHAH I FREAKING NEED HELP I NEED SO MUCH HELP I MIGHT FREAKING DIE
Sergeu [11.5K]

Answer:

  125°

Step-by-step explanation:

The angle marked f° is called an "external angle" of the triangle. Relative to that external angle, the two internal angles marked 44° and 81° are called "remote internal angles." Because f° and the adjacent internal angle are supplementary (add to 180°), and because all of the internal angles of the triangle add to 180°, the measure of f is equal to the sum of the remote interior angles:

  f° = 44° + 81°

  f° = 125°

1200 mm long and 800 mm wide. What is the area in square meters
alexgriva [62]

Answer: 0.96\ m^2

Step-by-step explanation:

We can make the conversion from milimeters to meters (Remember that 1m=1,000\ mm). Then:

1,200\ mm to m:

(1,200\ mm)(\frac{1\ m}{1,000\ mm})=1.2\ m

800\ mm to m:

(800\ mm)(\frac{1\ m}{1,000\ mm})=0.8\ m

Now, we need to use this formula for calculate the area of a rectangle:

A=lw

Where "l" is the lenght and "w" is the width.

Knowing that:

l=1.2\ m\\w=0.8\ m

We can substitute values into the formula. Then we get:

A=(1.2\ m)(0.8\ m)\\\\A=0.96\ m^2
