Answer:
a ≈ 14 or 6
Step-by-step explanation:
264 = π × a × (20 - a)
a(20 - a) =
≈ 84 (rounded off to nearest whole number)
Opening the brackets we get;
a² - 20a + 84 = 0
Applying the quadratic formula we get:
a ≈ 14 or 6
Answer:
The number of hamburgers is 109.
Step-by-step explanation:
Let h = number of hamburgers
Let c = number of cheeseburgers
The total number sold gives us the equation below.
h + c = 327
"The number of cheeseburgers sold was two times the number of hamburgers sold.
This gives us the equation
c = 2h
Now we substitute c with 2h in the first equation and solve for h.
h + 2h = 327
3h = 327
h = 109
The number of hamburgers is 109.
Answer:
1,114 people
Step-by-step explanation:
The equation
is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.
To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.
From 2000 to 2026,

have passed.
The expected number who will attend the fair in 2026 is


To the nearest whole number 1,114 people will attend in 2026
Answer:
See below.
Step-by-step explanation:
5a)
In an isosceles triangle, the angles opposite the congruent sides are congruent.
m<A = 40 deg
m<B = 40 deg
m<A + m<B + m<C = 180
40 + 40 + m<C = 180
m<C = 100 deg
5b)
In a right triangle, one angle is a right angle.
m<A = 40 deg
m<B = 90 deg
m<A + m<B + m<C = 180
40 + 90 + m<C = 180
m<C = 50 deg
