Answer:
See explanations below
Step-by-step explanation:
Sin 0 = x
0 = arcsinx
Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)
cos 0 = 1 (by punching the calculator)
tan 1 = 0.0174
All this values can easily be gotten directly from calculators
Irene has a spinner with 5 sections, each with a different color. Irene spins the spinner many times, and records the results in the table.
Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10
Find the probability of spinning each color, based on the data. Explain how you calculated each probability.
Step-by-step explanation:
Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.
Total frequency = 16 + 11 + 9 + 14 + 10 = 60
Hence we have the following probabilities:
P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6Sheila is biking at a constant speed. She travels 54 meters in 9 seconds.

Answer:
15
Step-by-step explanation:
54 divided by 9 = 6 90 divided by 6 = 15
Give the y-interecept
3x + y = 5
(Remember that to find the y-intercept, you need to make the x value a 0.)
(-3, 0)
(-3, 3)
(0, 5)
(5, 0)
Answer:
(0, 5)
Step-by-step explanation:
3x + y = 5
Plug x = 0
3*0 + y = 5
0 + y = 5
y = 5
y-intercept = (0, 5)

The length of AB is four times the length of BC.
AC = 75 cm.
Work out the length of AB.
Answer:
Let length of bc be x cm
Thus, ab=4x
ab+bc=ac
4x+x=75
5x=75
x=75/5
x=15
Therefore, ab=x=15cm
bc=4x=60cm

Math homework, a bit tired out and can't really do an equation without getting sidetracked.
Answer:
C
Step-by-step explanation:
Using Pemdas:
3 (1 + 4) / 3 + 4^2
3 (5) / 3 + 4^2
3 (5) / 3 + 16
15 / 3 + 16
Answer:
A
Step-by-step explanation:
First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis. simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.
When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.
When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.
When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.
Therefore, Equation A is the correct answer.
3.8x=2.736
what is x?
Answer:
x = 0.72
Step-by-step explanation:
Given
3.8x = 2.736 ( divide both sides by 3.8 )
x = 0.72
Answer:
x = .72
Step-by-step explanation:
2.736 ÷ 3.8 = .72
3.8(.72) = 2.736

Perry used the formula V (t) = 24,450(1-0.13)
to find the value of his car t years after he purchased it.
What does 0.13 represent?
A the price of the new car
B the time of year the car was purchased
the value of the car after t years
a 13% decrease in value each year
Answer:
D) a 13% decrease in value each year
Step-by-step explanation:
Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.
What does 0.13 represent?
The expression given above represents and expression of exponential decrease.
This is represented by the formula
y = a(1 - r)^t
Where
y = Value after time t
a = Initial value
r = Rate of decrease
t = Time
Comparing both expressions
y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t
We can see that:
r = 0.13
This is the rate of decrease.
Converting to Percentage = 0.13 × 100
= 13%
Option D is the correct option.

Each square below represents one whole. What precent is represented by the shaded area!!! PLEASE HELP!!!
Answer:
75%
Step-by-step explanation:
To break it down, there are four congruent triangles. In the first square, both are shaded completely, which is 50%. In the second square only one is shaded, which would be 25%. 50 + 25 = 75% or 3/4
Answer:
150%
Step-by-step explanation:
There is one full square = 100%
There is a half-filled square = 50%
add those percentages and you get 150%
I didn’t think it’d be that simple, sorry

Latoya made $147 for 7 hours of work.
At the same rate, how much would she make for 9 hours of work?
help pls
Answer:
$189 in 9 hrs
Step-by-step explanation:
Division is one of the four fundamental arithmetic operations. The amount that Latoya will make by working 9 hours is $189.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Latoya made $147 for 7 hours of work. Therefore, we can write,
Money made in an hour = Total Amount / Number of hours
= $147 / 7 hours
= $21 per hour
Now, the amount that Latoya will make in 9 hours will be,
Amount for 9 hours of work = Money made in an hour × Number of hours
= $21 per hour × 9 hours
= $189
Hence, the amount that Latoya will make by working 9 hours is $189.
