Answer:
1. Supplementary
2. Alternate exterior
Step-by-step explanation:
1. ∠1 and ∠2 are complementary because they both lie on the same straight line. If you had the values of these angles, they would add up to 180°
2. ∠1 and ∠8 are alternate exterior angles because they are on opposite sides of the transversal (the diagonal line from the bottom left to the top right) and they are on the outsides of the parallel lines. (∠1 is above the top horizontal line and ∠8 is below the bottom horizontal line.)

What exactly is a proportion?A percentage is a component of a total amount, and the measures are related by the rule of three.
Keep in mind that in a particular ratio, such as: a/b=c/d a*d=b*c
Create the following ratio for each ingredient:1/8 cup butter, 5/8 ounces of unsweetened chocolate, 1/4 cup sugar, 1/8 teaspoon vanilla, 1/2 egg, and 3/16 cup flour.
Explanation:
Given that the original recipe calls for 16 brownies;
Butter:
(1/8)/16=b/12
(2/3)(12)=16b
8=16b
b=1/2
Chocolate:
5/16=c/12
60=16c
c=60/16
c=15/4
Sugar: (3/2)/16=s/12
(3/2)(12)=16s
18=16s
s=18/16
s=9/8
Vanilla: 2/16=v/12
24=16v
v=3/2
Eggs: 2/16=e/12
e=3/2
Flour:1/16=f/12
f=3/4
As a result, the following would be the components for four brownies,
3/4 cups flour, 1/2 cups butter, 15/4 ounces unsweetened chocolate, 9/8 cups sugar, 3/2 teaspoons vanilla, and 3/2 eggs.

What is arithmetic?
Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, involution, and extraction of roots.
Main BODY:
Let X be the number of professors and Y be the number of lecturers. As the total of both is 228:
X + Y = 228
Then, as there are 5 professors for every 14 lecturers:
5 X = 14 Y or X = (14/5) Y
Replacing this last value of X on the first equation:
(14/5) Y + Y = 228
(14/5) Y + (5/5) Y = 228
(19/5) Y = 228
Y = 228 * (5/19)
Y = (228*5)/19
Y = 1140 / 19
Y = 60
Then we can find X:
X = (14/5) Y = (14/5) * 60 = 168
X = 168
Hence thre are 60 professors and 168 lecturers.

1. The population of a city increases by 4%, Find the increase in the population after 3 years if the original population is 22,000
Answers
Answer: 2640
Steps:
There are different ways you can solve this
METHOD 1
1. Find what 4% of 22,000 is
0.04 × 22,000 = 880
You do this so that you can find out the increase from the original number of people in the city
2. Find out what 3 years of increase is
880 = 1 year's worth of increase
880 × 3 = 3 year's worth of increase
2640 = 3 year's worth of increase
Therefore the population increase is 2640 ( 12% )
METHOD 2
1. Find out what 12% of 22,000 is
4% = 0.04
12% = 3 × 0.04
12% = 0.12
12% of 22,000 = 0.12 × 22000
12% of 22,000 = 2640
Therefore the population increase is 2640 ( 12% )

A single card is drawn from a standard 52 card deck fund the conditional probability that the card is a spade given that it is a 10
Answers
When the card is a jack, there is a 0.25 probability that you will receive a spade.
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability.
The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
In order to better grasp probability, let's look at a straightforward application. Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.
There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.
According to our question-
P(Spade) = 13/52 = 1/4 P(Jack) = 4/52
= 1/13 P(Spade and Jack)
= (1/4)(1/13) = 1/52 P(Spade/Jack)
= P(Spade and Jack)/P(Jack)
= (1/52)/(1/13) = (1/52)(13/1)
= 13/52 = 1/4 = 0.25
Hence, When the card is a jack, there is a 0.25 probability that you will receive a spade.

trying to find the arc length of the arc for the polar curve r=8cosθ between 0 and π4
Answers
Answer:
Step-by-step explanation:
To find the arc length of the polar curve r = 8cosθ between 0 and π/4, we can use the formula for arc length:
L = ∫a^b √(r^2 + (dr/dθ)^2) dθ
Substituting in the values for r and dθ, we get:
L = ∫0^(π/4) √(8^2cos^2θ + (-8sinθ)^2) dθ
= ∫0^(π/4) √(64cos^2θ + 64sin^2θ) dθ
= ∫0^(π/4) √(64) dθ
= ∫0^(π/4) 8 dθ
= 8(π/4 - 0)
= 8π/4
= 2π
Therefore, the arc length of the polar curve r = 8cosθ between 0 and π/4 is 2π.

Answers
After solving, the maximum height of the ball is 90.25 feet.
In the given question,
A person standing close to the edge on top of a 48-foot building throws a ball vertically upward.
The quadratic function
h(t) = -16t^2+52t + 48 models the ball's height about the ground, h(t) in feet, t seconds after it was thrown.
We have to find the maximum height of the ball.
Height is given that;
h(t) = -16t^2+52t + 48
Now comparing the given equation by the standard equation ax^2+bx+c=0
Here b = 52, a = -16
For maximum height put t= -b/2a
t = -52/2(-16)
t = 52/32
t = 1.625
Maximum height
h(1.625) = -16(1.625)^2+52(1.625) + 48
h(1.625) = -42.25+ 84.5 + 48
h(1.625) = 90.25 feet
