I’m confused on this one

Remark

I would have had the answer a whole lot sooner if I would have read the question properly. The figure in the circle is called a cyclic quadrilateral. It has the odd property that the angles that are opposite each other add up to 180o.

So DEB + DCB = 180o

DEB = 180 - 87

DEB = 93o

Note: The arcs marked 60 and 76 have nothing whatever to do with this problem.

Find the slope<br> of each line (picture below thank u )
Alekssandra [29.7K]

1.  order pairs : (3,1), (-2,-1)

1 + 1 / 3 + 2 = 2 / 5 is the slope

2.  order pairs : (2,-3), (-3,2)

-3 - 2 / 2 + 3 = - 5 / 2 is the slope

3.  order pairs : (1,3), (-1,-2)

3 + 2 / 1 + 1 = 5 / 2 is the slope

I used the slope formula to get my answers.

Answer: 1.5%

Step-by-step explanation:

The Pure Interest Rate refers to the rate in a theoretical market where there is no risk as economic conditions can be predicted with certainty.

Sadly, uncertainty will always exist but there are rates that are close enough to the Pure interest rate such as US Government Security rates.

The United States has never defaulted on a debt payment in the modern era and as such is known to offer the least risky rates in the world. The rate on US Securities can therefore be considered as close as possible to the pure interest rate.

Given the rates in the question, the Pure Interest rate would be the 20-year Treasury bond rate of 1.5%.

Answer:

  80.99 m

Step-by-step explanation:

The hypotenuse of the triangle is given, and the desired side length is the one adjacent to the angle marked. The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

Multiplying by the hypotenuse, we find ...

  RY = (82 m)cos(9°) ≈ 80.99 m

A certain school has 120 teachers. If this constitutes 30% of its workforce, find the number of employees in the school.​
Ilya [14]

Answer:

400 employees

Step-by-step explanation:

Let the total no. of employees be x

From the information we get that,

30% of x= 120

Hence, 30/100x=120

x=120×100/30

x=400
