Circle Q is centered at the origin and has a radius of 9 units. which equation could represent circle Q
Answer:
x^2 + y^2 = 81
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by ;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center of the circle which is the origin in this case. The origin has the coordinates (0,0)
the radius here is 9 units
Thus, the equation of the circle would be;
(x-0)^2 + (y-0)^2 = 9^2
= x^2 + y^2 = 81
Food Mart and Jan’s Store sell boxes of the same type of breakfast cereal.
Each shop has a special offer.
food mart has 400 g, 20% off the normal price of £5
jans store 400 g plus 30% extra £5
Which box of cereal is the better value for money?
You must show your working
someone help pleaseee
Answer:
The box of cereal bought at Farm store is a better value for money
Step-by-step explanation:
To answer this question question, we will need to be making a comparison. The comparison i will like to make with the two offers is price per grammes ( £/g). The offer with a better price or higher price per grammes win.
Let’s proceed!
For the food mart,
we are paying 20% off £5 for 400g
let’s calculate 20% off £5
That would be 5-(20/100 * 5) = 5-1 = £4
The price per grammes here is £4/400g = £0.01/g
For Jans store ;
we have 400g plus 30% extra at £5
What we need do here is to first calculate 30% extra of 400g
Mathematically, that would be 30/100 * 400 = 120
Total grammes here is 120 + 400 = 520g
Price per grammes here would be ; £5/520g = £0.00962/g
This is lesser than what we have at Food mart as 0.01 > 0.0096
The function f(x)=200/x + 10 models the cost per student of a field trip when x students go on the trip. How is the parent function f(x)=1/x transformed to create the function f(x)=200/x + 10
Answer:
Step-by-step explanation:
We need to explain the transformations applied to 1/x to get f(x). We get f by following the following steps.
1. Multiply 1/x by 200 to get the function 200/x. This represents taking the graph of 1/x and expanding it vertically by a factor of 200.
2. Sum 10 units to 200/x. This represents a vertical shift of 10 units to the graph of 200/x.
Maris put trim around a mirror that is the shape of a square. Each side is 24 inches long. Maria has 1 foot of trim left. What was the length of the trim when she started? Write your answer in yards
Answer:
16.028 yards
Step-by-step explanation:
1 inch=0.0833333 foot
24 inches=0.0833333×24
=1.9999992 foot
The mirror is square shaped and each side is 24 inches
If each 24 inches=1.9999992 foot
Then,
4 sides of 24 inches=1.9999992×24
=47.9999808 foot
Maria has 1 foot of trim left
Total Length of trim when she started=47.9999808+0.0833333
=48.0833141 foot
=16.02777136667 yards
Approximately,

Find the area of the shaded triangle
Area of a triangle is 1/2 x base x height.
The base of the shaded triangle is 2 ft. the height is 4 ft.
Area = 1/2 x 2 x 4 = 4 square feet.
Answer:
4 ft²
Step-by-step explanation:
A = 1/2bh Use this equation to find the area of the triangle
A = 1/2(4)(4) Multiply
A = 1/2(16) Multiply
A = 8 Area of entire triangle
A = 1/2(2)(4) Multiply
A = 1/2(8) Multiply
A = 4 Area of triangle not shaded
Take the area of the whole triangle minus the area of the unshaded part
8 - 4 = 4 ft²

(Choice A)
There were the most observations of female tokoeka kiwis.
(Choice B)
Great spotted kiwis were more likely to be male than female.
(Choice C)
More than half of the kiwis were Northland brown kiwis.
(Choice D)
Northland brown kiwis were more likely to be female than tokoeka kiwis were.
Answer:
A.
I hope it helps
There were the most observations of female tokoeka kiwis in the given frequency table so option (A) will be correct.
What is a frequency table?A frequency table is a list of objects with the frequency of each item shown in the table.
The frequency of an occurrence or a value is the number of times it happens.
Given the frequency table of kiwi birds with their gender.
Number of female tokoeka kiwis = 44
Now if we look at the table there is none of any bird that is greater than 44 which means it is the most observations in the research.
Hence "There were the most observations of female tokoeka kiwis".

When trying to find solutions to the system of equations x+y=3 2x+2y=6 you take several correct steps that lead to the expression 0=0. Which statement is true?
Answer:
They are the same equations. (I don't know what you mean by "true.")
Step-by-step explanation:
If you divide 2x + 2y = 6 by 2, it turns into x + y = 3. This means that the graphs of the lines are the same, or there are infinite solutions.
I am really sorry if this is wrong because I am not really sure what you meant by "Which statement is true?"

Find the volume of a pyramid with a square base, where the area of the base is
8.7 m and the height of the pyramid is 10 m. Round your answer to the nearest
tenth of a cubic meter.
Answer: 29.0
Step-by-step explanation:
The volume of a pyramid is equal to l*w*h/ 3 and we know that the length times the width is the same as the base.
so we will multiply 8.7 * 10= 87 /3= 29
Volume = 87 m³
You need to multiply the area and the height to find the volume. If you have the length, width, and height, then you need to multiply and 3 and divide it by 3. Hope I helped :)

Answer:
A, C and D
Step-by-step explanation:
In this question, we are asked to select which of the options is/are example(s) of compound event(s)
The easiest way to answer this is to have an idea of what we mean by a compound event. When we talk about a compound event, we are referring to an event that has more than one outcome. This is a direct contrast to a simple event where we have only one outcome. To find the probability of a compound event, we shall need to add up the probabilities of all the single events that lies there in
In answering this question, we shall be considering the options one after the other.
A. It is a compound event
This is because we are looking at more than one event happening
B. It is not a compound event
It is not a compound event as we have only one outcome
C. This is a compound event
We have more than one outcome here. In fact, we are dealing with more than one sample space here
D. It is a compound event
We are working on different simple events here
E. It is not a compound event
It is not because we are only focused on a particular type of outcome
Answer:

Scientists often use the catch, band, and release method to estimate the size of wildlife populations. For example, 250 trout were caught, banded, and released into a small lake in Northern Ontario. One month later, another 250 trout were caught in the lake, 30 of them had bands. From this information scientists could estimate the size of the trout population of the lake. What is the expected population of trout? How do you know?
Answer:
2083.33 trouts
Step-by-step explanation:
Total population of fish in the pond is unknown, therefore, let's us represent this using letter Z
The ratio of banded , caught and released trout to the total trout population is represented as 250 : Z
We can solve this type of problem with a proportion:
Total number of fishes that was tagged and caught/ Total number of fishes that was caught = Total number of tagged fishes in the pond/ Total number of fishes in the pond.
In the question, we were given this values:
Total number of banded trout's that was caught and released into the pond = 250
Total number of trouts that was caught and had bands in the lake= 30
Total number of trouts that was caught in the lake = 250
Total number of fishes in the pond = Z
Hence we have:
30/250 = 250/ Z
We cross mulitply
30× Z = 250 × 250
30Z = 62500
We divide both sides by 30
30Z/ 30 = 62500/30
Z = 2083.33
Therefore, the expected population of trout is 2083.33 trouts
