Check out the attached image. Since the two angles PQS and SQR are adjacent and form angle PQR, this means we simply add up the angles

(Angle PQR) = (Angle PQS) + (Angle SQR)

Angle PQR = 87 + 33

Angle PQR = 120 degrees

I've tried to get the answer for this 13 times now (not joking), plzzz help: write a formula that represents the number of peopl

gtnhenbr [62]

Answer:

2820 seats
aₙ = 3n + 9

Step-by-step explanation:

This is an AP with:

The first term a₁ = 12
Common difference d = 3
Number of terms n = 40

Number of the seats:

Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

Formula of nth term:

aₙ = a₁ + (n - 1)d
aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
aₙ = 3n + 9

What is the slope of the line that passes through the points (2, 5) and (7, 3)?

lana66690 [7]

ANSWER: $\frac{2}{-5}$

EXPLANATION:

We can use the slope formula and input the x and y values to solve for the slope.

$\text{Slope Formula}: \frac{y_{2}-y_{1} }{x_{2}-x_{1}}=m$

$\frac{5-3}{2-7}=m\\\text{Simplify.}\\\frac{2}{-5} =m$

The slope of the line is $\frac{2}{-5}$
