In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0
Answers
Answer:
Terminal point: (0, 1); sinФ = 1 ⇒ A
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 90°
→ By using the 2nd rule above
∴ The terminal point is (0, 1)
∴ sinФ = 1
∴ Terminal point: (0, 1); sinФ = 1

8. A school raffle sold 480 tickets. Students were charged $1/ticket and teachers $5/ticket. The total receipts were $560. How many of each ticket were sold? 9. An airplane travels 5432 km. On the outward trip it took 7 hours with the wind. On the return trip, it took 8 hours against the wind. What was the speed of the plane and the speed of the wind? (Remember: distance = speed x time)
Answers
Answer:
8. Number of student tickets = 460
Number of teacher tickets = 100
9. Speed of plane = 727.5 km/hr
Speed of wind = 48.5 km/hr
Step-by-step explanation:
8.
Let number of students' tickets = [tex]x[/tex]
Let number of teachers' tickets = [tex]y[/tex]
Total number of tickets = 480
[tex]x+y=480[/tex] ...... (1)
Price for one student's ticket = $1
Price for one teacher's ticket = $5
Total money collected by the tickets = $560
[tex]x +5y = 560[/tex] ...... (2)
Subtracting (1) from (2):
[tex]4y = 80\\\Rightarrow y = 20[/tex]
By equation (1):
[tex]x = 460[/tex]
Number of student tickets = 460
Number of teacher tickets = 100
9.
Let the speed of airplane in still air = [tex]u[/tex] km/hr
Let the speed of air = [tex]v[/tex] km/hr
Total distance = 5432 km
Time taken with the wind = 7 hours.
Speed with the wind = [tex]u+v[/tex] km/h
Time taken against the wind = 8 hours.
Speed with the wind = [tex]u-v[/tex] km/h
Using the formula:
Distance = Speed [tex]\times[/tex] Time
[tex]5432 = (u+v)\times 7\\\Rightarrow u +v = 776 .... (1)[/tex]
[tex]5432 = (u-v)\times 8\\\Rightarrow u - v = 679 .... (2)[/tex]
Adding (1) and (2):
[tex]2u = 1455\\\Rightarrow u = 727.5\ km/hr[/tex]
By equation (1):
[tex]v = 48.5\ km/hr[/tex]
Speed of plane = 727.5 km/hr
Speed of wind = 48.5 km/hr

Answers
Complete question :
A parachutist's speed during a free fall reaches 162 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.
Answer:
45 m/s ; 900 meters
Step-by-step explanation:
Given that :
Speed = 162 kilometers per hour ;
The speed in meters per second can be found by:
162 km/hr = (162 * 1000)m / (60 * 60) second
162 km/hr = 162000m / 3600 s
162 km/hr = 45 m/s
At this speed, how many meters will the parachutist fall during 20 seconds of free fall?
Speed of free fall = 45m /s
Distance in meters after 20 seconds :
(45 m/s * 20s) = 900 meters

Answer: It will hold 7.6 Litres
Step-by-step explanation:
Step 1
We know that Converting Gallons to Litres, we have that
I gallon = 3.78541
So from the question
A large bucket = 5gallons which in Litres became
5 x 3.78541=18.927 rounded up to 19litres.
-- Also IF 5 Gallons = 19 Litres
Then 1 Gallon = 19/5= 3.8 Litres
Step 2
IF large bucket of 5 gallons = 19 Litres ,
A small bucket of 2 gallons of water = 2 x 19/5= 38/5 =7.6 Litres

A 32-ounce package of a snack mix is 24 percent pretzels. How many ounces are pretzels?
0.706 ounces
0.768 ounces
7.06 ounces
7.68 ounces
Answers
Answer:
the correct answer is choice D. if 24 precent of the snack mix is pretzels we simply need to multiply the total number of ounces by 0.24 7.68 ounces of the snack mix will be pretzels
D. 7.68 ounces
Explanation:
What we know:
- the snack mix is 32 ounces
- 24% of the snack mix is pretzels
To find the ounces of pretzels, find 24% of 32 ounces by multiplying them.
24% = 0.24 as a decimal
0.24*32=7.68
Therefore, 7.68 ounces are pretzels.

if the length of two sides of a triangle are 7 and 10 the length of the third side may be
A. 1
B.3
C.2
D.4
explain
Answers
Answer:
D. 4
Step-by-step explanation:
Let's look at all the options first. All of the options are below 7 and 10, hence we can deduce that it is not the hypotenuse. Looking at 7 and 10, we see that 10 is the larger number, and hence we know that 10 is the hypotenuse.
Hence, as the other two sides added up in a triangle must be larger than the hypotenuse, the only available option is 4, since 4 + 7 = 11 > 10.

Answer: I think it’s 0.1 or 1/10 but I’m kinda confused
Step-by-step explanation: someone pls correct me if I’m wrong
1/2 is 0.5
2/5 is 0.4
0.5-0.4=0.1
0.1=1/10
1/10 of carrot, fluffy will eat at night.
What is fraction?Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator, below one is called denominator
Given,
Fluffy bunny ate 1/2 of a carrot in the morning
By the end of the day he ate 2/5 of left carrot = 2/5
Whole carrot can be considered as 1.
Carrot left after eating 1/2 of it in the morning
= 1 - 1/2
= 1/2
Carrot left after eating 2/5 part
= 1/2 - 2/5
= (5 - 4)/10
= 1/10
Hence, fluffy ate 1/10 of carrot at night.

p,q are integers then (p-6q)/2q is a rational number.

Answers
explanation: you have to find the least common denominator of the two numbers. to do that you must think “can both these numbers be divided by 2? 3? 4?” and so on. you will find that 5 is the least common denominator, so you divide both numbers by 5 and end up with the simplest form which is “5:3”
The required simple ratio of the given ratio of girls to boys at a party is 5 : 3.
Given that,
The ratio of girls to boys at a party is 25:15. To write this as simple.
In mathematics, it deals with numbers of operations according to the statements.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
The ratio of girls to boys at a party is 25:15,
= 25 / 15 implies there are 25 girls over 15 boys in the school party,
= 5 * 5 / 5 *3
= 5 / 3 it implies there are 5 girls over 3 boys in the school party.

The number of fish in a lake decreased by 25% between last year and this year. Last year there were 60 fish in the lake. What is the population this year?
Answers
Answer:
This population, the population is 45 fish.
Step-by-step explanation:
This problem can be solved by a rule of three.
Last year there were 60 fish in the lake. That was 100, that is, decimal 1.
This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So
60 fish - 1
x fish - 0.75
x= 60*0.75
x=45
