Answer:
90
Step-by-step explanation:
A semicircle is 1/2 of a circle
A circle is 360 degrees
1/2 is 180
We have 90 degrees already used on the left
180-90 = 90
b = 90 degrees
Answer:
90
Step-by-step explanation:
The whole thing equals 360
so have equals 180
and half of one 180 is 90 and you're trying to find that half of 180.

Among the given tables, only the table with y-values doubling as x increments by 1 represents an exponential function. This is characterized by a constant proportional rate of change in the y-values in relation to x.
Explanation:The question asks to identify which of the given tables models an exponential function. An exponential function is a mathematical function in the form [tex]f(x) = a · b^x,[/tex] where a is not zero, b is a positive real number not equal to 1, and x is any real number. The key characteristic of an exponential function is that the rate of change (the increase or decrease) is proportional to its current value, meaning as x increases, the value of y increases or decreases at a rate proportional to its current value.
x y
0 5
1 7
2 9
3 11
This does not represent an exponential function because the increase in y is linear.
x y
0 5
1 10
2 20
3 40
This table models an exponential function since each y-value is doubling as x increases by 1.
x y
0 5
1 6
2 8
3 11
This does not model an exponential function because the growth does not follow a constant ratio.
x y
0 5
1 10
2 15
3 20
This also does not represent an exponential function as the increase in y is linear, similar to the first table.
Therefore, the table that models an exponential function is the one where the y value doubles as x increments by 1.

Which value is represented by point P?
A. sqrt11
B. sqrt21
C. sqrt114
D. sqrt121
Square root 114 represents the point p.
Given,
The point P value in the given figure is between 10 and 11.
We need to find which value in the option is represented by point P.
Given options are :
Sqrt 11 = 3.31
Sqrt 21 = 4.58
Sqrt 114 = 10.67
Sqrt 121 = 11
We need to see which option gives a value between 10 and 11.
We have,
Sqrt 114 = 10.67.
We also know that point P lies between 10 and 11.
Sqrt 114 gives a value between 10 and 11.
Thus Sqrt 114 represents the point p.

18pi rounded to the nearest whole number
Answer:
56.52 but you have to round so its 57
Step-by-step explanation:
You have to multiply 18 and pi so we will use 3.14 for pi. 18 times 3.14 will give you 56.52 but you have to round it so it will be 57. If the number is greater than 5 you round up but if it is less you round down.

A circus charges $5 per child ticket and $8 per adult ticket. There were 136 tickets sold for a total of $830. How many child tickets and how many adult tickets were purchased?
I know that I need to use c + a =136 and 5c + 8a = 830
Answer:
50 adult
86 child
Step-by-step explanation:
c + a =136
5c + 8a = 830
These are the two equations to use
c is the number of child tickets and a is the number of adult tickets
The total number of tickets is 136
The child tickets are 5 dollars apiece and the adult tickets are 8 dollars apiece and the total amount made is 830
I will use elimination
Multiply the first equation by -5
-5(c+a) = -5*136
-5c-5a =-680
Then add this to the second equation
-5c-5a =-680
5c +8a = 830
------------------------
3a = 150
Divide each side by 3
3a/3 = 150/3
a = 50
Now we can find c
a+c = 136
50 + c = 136
Subtract 50 from each side
50+c-50 =136-50
c = 86
Answer:
child tickets: 86
adult tickets: 50
Step-by-step explanation:
C + A = 136
C = 136 - A
5C + 8A = 830
5(136 - A) + 8A = 830
680 - 5A + 8A = 830
3A = 150
A = 50
C = 136 - 50
C = 86

A park has a shape of a regular hexagon of sides of 2km each.Ama walks a distance of 5km along the sides of the park.What is the direct distance between the start point and the end point?
Answer: 3.61km or √13
Step-by-step explanation:
Given Data:
Sides of hexagon = 2km each
Distance walked by Ama = 5km
Therefore;
Let Ama starting position be the origin.
With this She would travel along two edges and then go halfway along a third.
Her new x- coordinate would be
= 1 + 2 + 1/2 = 7/2
Because she travels a distance of 5km which translates to 2 and half side of the Hexagon
= 2*1/2
= 1km. On her x-coordinates
For her y-coordinate we use same principles as x-coordinates
= √3 + 0 - √3/2
= √3/2
Therefore her distance walked
= √ ( (7/2)^2 + (√ 3/2)^2 )
= √ ( 49/4 + 3/4 )
= √ 13
= 3.61km

A bag contains 7 red marbles, 4 blue marbles and 5 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be green?
The probability of drawing three green marbles consecutively without replacement from a bag containing different colored marbles is approximately 0.018 when calculated step by step.
Explanation:The question is about calculating the probability of drawing three green marbles in a row from a bag that contains multiple colored marbles. To find this probability, we need to use the concept of probability without replacement.
First, calculate the probability of drawing one green marble. There are 5 green marbles out of a total of 16 (7 red + 4 blue + 5 green), so the probability is 5/16. When we draw a green marble, we do not replace it, so there are now 4 green marbles left out of 15 total marbles. The probability for the second draw is then 4/15. Lastly, for the third draw, there are 3 green marbles out of 14, making the probability 3/14.
To find the overall probability of all three events occurring, calculate the product of the individual probabilities: (5/16) * (4/15) * (3/14). This gives us 60/3360, which simplifies to 1/56. To the nearest thousandth, that is approximately 0.018.
So the probability that all three marbles drawn will be green, to the nearest thousandth, is 0.018.

A 10-foot ladder is leaning against a tree. The bottom of the ladder is 4 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach? 2.4 feet 6.0 feet 9.2 feet 10.8 feet
Answer:
C
Step-by-step explanation:
If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.
Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:
h = [tex]\sqrt{10^2-4^2} =\sqrt{84}[/tex] ≈ 9.2 feet
The answer is C.
Answer:
9.2 feet
Step-by-step explanation:
The ladder forms a right angle triangle with the ground and the tree
10² = 4² + h²
h² = 100 - 16
h² = 84
h = 9.16515139

0.05 x 365 = 18.35
18.25 x 3 = 54.75
Answer:
54.75
Step-by-step explanation:
To find this answer we will first take our 3 years and turn them into days instead.
There are 365 days in a year, so, 365 x 3 = 1095 days
Next, take the 1095 days and multiply it by the number she is saving everyday
1095 x .05 = 54.75

Michael recorded the number of points his team scored for the first seven basketball games.
64, 58, 60, 52, 56, 62, 54
which box plot correctly represents the data?
Answer:
The first box.
Step-by-step explanation:
The minimum is 52, the max is 64, the median is 58.
The correct option is A.
Given,
The number of points scored for the first seven basketball games.
64,58,60,52,56,62,54
On arranging it in increasing order we get,
52,54,56,58,60,62,64
The above data is ungrouped data.
We know that, The median of ungrouped data is the middle term (when the total no. terms in data is odd) on arranging the data in ascending or descending order.
So here on arranging the above data, the middle term here is 58, hence the median here is 58.
The minimum score is 52 and the maximum score is 64.
On seeing the options we find that the option A is correct because here the minimum value is 52 and the maximum is 64 and median is exactly 58.
Hence, option A is correct.
