Answer:
31.42 m
Step-by-step explanation:
Since, the path is circular :
The distance traveled can be I tin by taking the Circumference of the path :
Circumference, C = πd
d = diameter = 20 meters
C = π * 20
Since penguin swam. Only halfway around the island.
Hence, distance traveled = 1/2 * C
= 1/2 * 20π
= 31.42 m

Answer:
x = 40
Step-by-step explanation:
Measure of an external angle of a circle = ½(difference of the intercepted arcs)
This means that:
½(PQ - RS) = m<T
m<T = x/2
PQ = (x + 70)°
RS = (x + 30)°
Plug in the values
½((x + 70) - (x + 30)) = x/2
½(x + 70 - x - 30) = x/2
½(x - x + 70 - 30) = x/2
½(0 + 40) = x/2
½(40) = x/2
20 = x/2
Multiply both sides by 2
20*2 = x
40 = x
x = 40

A savings account starts with $181.25. After 7 years of continuous compounding at an interest rate, r, the account has $1450. What is the interest rate percentage? Round the answer to the nearest hundredth.
Rate of interest by which amount $181.25 becomes $1450 in 7 years by continuous compounding will be 29.71%.
Rule for the continuous compounding: Expression for the final amount comounded continuously is given by,
Final amount = [tex]Pe^{rt}[/tex]
Here, P = Principal amount
r = Rate of interest
t = Duration of investment
Given in the question,
P = $181.25
t = 7 years
Final amount = $1450
Substitute these values in the expression,
[tex]1450=181.25e^{7r}[/tex]
[tex]e^{7r}=8[/tex]
[tex]\text{ln}(e)^{7r}=\text{ln}(8)[/tex]
[tex]7r=2.07944[/tex]
[tex]r=0.2971[/tex]
[tex]r=29.71\%[/tex]
Therefore, rate of intereset for the investment is 29.71%.

Answer:
C. As the Test Score increases, the Social media time decreases
Step-by-step explanation:
D. Yes, linear because if I were to draw a line on the graph most of the points on the scatter plots would match?
Answer:
C. As the Social media time increases, the Test score decreases.
D. Yes, I think the relationship between the test scores and social media time appears liner, because linear lines tend to be straight, and has a constant rate of change. In this case, there is a constant rate of change, and the plot points aren't all over the place.
Explanation (sort of):
Look at the graph going from left to right; You will see that the plot points continue to "fall" closer to the x-axis. This is why "Test scores" are decreasing instead of "Social media time", unlike what someone else answered with.

b. 9%
c. 11.11%
d. 18%
please answer asap!
The required interest rate on the Bakas loan for the piano is 9%.
Given that,
Baka borrows $3,000 to buy a piano. The simple interest owed at the end of 2 years is $540. what is the annual interest rate on Baka loan for the piano is to be determined.
When some apply for their money on something so that they can get higher value in returns of their money.
Here,
Simple interest = principal × rate × time / 100
Substitute value in the above equation,
540 = 3000 × rate × 2 / 100
Rate = 540 × 100 / 3000 × 2
Rate = 9%.
Thus, the required interest rate on the Bakas loan for the piano is 9%.

A company makes 150 bags.
23 of the bags have buttons but no zips.
35 of the bags have zips but no buttons.
49 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer:
66/150
Step-by-step explanation:
So the question asks the probabilty for buttons.
so we see that 23 has buttons so we discard for now,
35 has no buttons but a zip so we acknowledge it
49 has no buttons and no zips so we keep it too.
now we do 35+49 which is 84.
since there is 150 bags and 84 of those bags dont have buttons, the rest must do.
150-84=66
so there are 66 bags with buttons so we put this in a fraction -> 66/150
Tangent (non necessary for the question persay):
since we cant simplify you keep it as 66/150. If you are doing this on mathswatch, then remeber if there is a question like this next and you can simplify, simplify.
for this question it is not necessary.

The probability that the bag is selected at random have buttons is 11/25.
What is probability?Probability is the chance of happning an event among all the events possible. It lies between 0 and 1. It is calculated by dividing number of items by total number of items.
How to calculate probability?We have been given that company makes 150 bags out of which 23 of the bags have buttons but no zips and we have to calculate the probability that a bag chosen at random have buttons.
35 of the bags have zips but no buttons.49 of the bags have neither zips nor buttons.so we see that 23 has buttons so we discard for now, 35 has no buttons but a zip so we can say that it that 49 has no buttons and no zips so we keep it too.now we do 35+49 which is 84. Because there are 150 bags and 84 of those bags dont have buttons, the rest must do.
150-84=66, we got that there are 66 bags with buttons so we put this in a fraction= 66/150.
Probability=66/150

Charlie does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at least 9 hours. He spends at most 12 hours on weight training. He spends at most 6 hours doing cardiovascular work. Let x denote the time (in hours) that Charlie spends doing cardiovascular work. Let y denote the time (in hours) that he spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.
Answer:
[tex](x_1,y_1) = (0,9)[/tex]
[tex](x_2,y_2) = (6,3)[/tex]
[tex](x_3,y_3) = (6,12)[/tex]
Step-by-step explanation:
Given
x = hours spent on cardiovascular work
y = hours spent on weight training
From the first statement,
Each week: he spends at least 9 hours
This is represented as:
[tex]Total \ge 9[/tex]
[tex]x + y \ge 9[/tex]
From the second statement,
Each week: he spends a max of 12 hours on weights
This is represented as:
[tex]Weight \le 12[/tex]
[tex]y \le 12[/tex]
From the third statement,
Each week: he spends a max of 6 hours on cardio works
This is represented as:
[tex]Cardio \le 6[/tex]
[tex]x \le 6[/tex]
So, the inequalities are:
[tex]x + y \ge 9[/tex]
[tex]y \le 12[/tex]
[tex]x \le 6[/tex]
See attachment for the graph where the solution are also highlighted
From the attachment, the solutions are:

X is directly proportional to y.work out the missing values,p and q, in the table
Answer:
p = 21, and q = 30
Step-by-step explanation:
If x is directly proportional to y, then we know:
y = 35x / 60
We can factor 5 out of that, giving us:
y = 7x / 12
We can also find the inverse of that relationship:
y = 7x / 12
12y = 7x
x = 12y / 7
So in the second row, where x = 36:
y = 7 × 36 / 12
y = 7 × 3
y = 21
And in the third row where y = 17.5:
x = 12 × 17.5 / 7
x = 210 / 7
x = 30
So p = 21, and q = 30
