Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}

\frac{-5}{4} + \frac{-1}{4}

The addition of a negative fraction is simply the subtraction by that fraction:

\frac{-5}{4} - \frac{1}{4}

\frac{-5 - 1}{4}

\frac{-6}{4}

Which can be simplified dividing by two both numerator and denominator:

\frac{-3}{2}

Ben made a model (shown below) of the square pyramid he plans to build when he grows up.
elena-s [515]

Answer:

336 m^2

Step-by-step explanation:

The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

A=A_b + 4A_t

where:

A_b=L^2 is the area of the base, where

L is the length of the base

A_t=\frac{1}{2}Lh is the area of each triangular face, where

h is the height of the face

Substituting,

A=L^2+2Lh

For the model in this problem,

L = 12

h = 8

Therefore, the surface area here is:

A=12^2 +2(12)(8)=336

A boat is 400 feet away from one dock and 500 feet away from the another dock. the angle between the paths is 45°. what is the a
FinnZ [79.3K]

Answer:

  • The approximate distance between the docks is 357 feet

Step-by-step explanation:

Let the distance between docks be d.

This is the opposite side to 45° angle of triangle with other sides 400 ft and 500 ft.

Use the law of cosines to find the value of d:

  • d = \sqrt{400^2+500^2-2*400*500*cos45} =357 (rounded)
