By using all the chocolate cream, at most the number of eclairs that can be made is:
C) 42
Step-by-step explanation:It is given that:
You have 12 cups of chocolate cream to fill eclairs.
Each eclair requires 2.25 ounces of filling.
We know that:
The universal conversion that is used is:
1 cups=8 ounces
and hence,
12 cups= 12×8=96 ounces.
Hence, the number of ounces of chocolate cream to fill eclairs= 96 ounces
Also,
amount of filling required by 1 eclair= 2.25 ounces.
Hence, Number of eclairs that can be made is:
[tex]Number\ of\ eclairs=\dfrac{96}{2.25}\\\\i.e.\\\\Number\ of\ eclairs=42.67[/tex]
This means that:
Atmost the number of eclairs than can be made= 42

Find the measure of arc BC
Answer:
Step-by-step explanation:
This problem does not specify what the radius of the circle is, and so we will have to represent that by r.
Arc length = s = rФ, where Ф is the central angle in radians.
Converting 162° into radians:
162° 1 rad
------- · ------------ = 0.9 rad
1 180°
Then the arc length BC is s = rФ, or r(0.9 rad)
If, for example, r = 10 m, then the arc length would be (10)(0.9) m = 9 m
Answer:
198
Step-by-step explanation:
360-162= 198
What is the measure of the major arc?
The answer is D) 210 because arc eog is 150 and is the minor arc. A whole circle is 360 therefore 360-150=210
The measure of the major arc is found by calculating the circumference of the entire circle 2πr and then using the proportion that the angle of the major arc represents out of 360 degrees.
Explanation:The measure of the major arc in a circle depends on the angle subtended by the arc at the center of the circle. If we define the angle Θ (theta) in degrees, that subtend the arc, the length of the major arc can be found by using the circumference of the entire circle, which is 2πr (where r is the radius), and the proportion of the circle that the major arc represents. Since the entire circle is 360 degrees, if the major arc corresponds to an angle Α, which is the complement of Θ (since Α + Θ = 360 degrees for the minor and major arcs together), the major arc length will be 2πr (Α/360). To summarize, if you're given the central angle of the minor arc or can otherwise determine the central angle for the major arc, you can use this proportion to calculate the arc length.

Find the surface area of the regular hexagonal pyramid. Round your answer to the nearest hundredth
Answer:A i guess i am soooooooooo sorry if i am wrong
Step-by-step explanation:
Answer:
(B) [tex]SA=79.18m^2[/tex]
Step-by-step explanation:
It is given from the figure, the side of the regular hexagonal pyramid is 3 m, slant height is 6.2 m and height is 5.6 m.
The formula for Surface area of the regular hexagonal pyramid is:
[tex]SA=\frac{pl}{2}+B[/tex]
where B is the area of the base, p is the perimeter and l is the slant height.
Now, the perimeter can be found as:
[tex]P=6{\times}3[/tex]
[tex]P=18 m[/tex]
And, the area of the base is:
[tex]B=\frac{3\sqrt{3}s^2}{2}[/tex]
Substituting the value of s in the above formula, we get
[tex]B=\frac{3\sqrt{3}(3)^2}{2}[/tex]
[tex]B=23.382m^2[/tex]
Now, substituting the values of B, and P in the formula of Surface area, we get
[tex]SA=\frac{18{\times}6.2}{2}+23.382[/tex]
[tex]SA=79.18m^2[/tex]
Thus, the Surface area of the regular hexagonal pyramid is [tex]79.18m^2[/tex].
Hence, option B is correct.

The equation of a circle is (x + 3)2 + (y – 5)2 = 81. Determine the coordinates of the center of the circle and the length of the radius.
Answer:
The center of the circle is (-3 , 5) and the length of the radius is 9 units
Step-by-step explanation:
* Lets revise the standard form of the equation of the circle
- The center-radius form of the circle equation is in the format
(x – h)² + (y – k)² = r², where the center is the point (h, k) and
the radius is r.
- This form of the equation is helpful, because you can easily find
the center and the radius.
* Now lets solve the problem
- The equation is (x + 3)² + (y - 5)² = 81
- By comparing the two equations
∵ (x – h)² + (y – k)² = r² and (x + 3)² + (y - 5)² = 81
# x - h = x + 3
∴ -h = 3 ⇒ divide both sides by -1
∴ h = -3
# y - k = y - 5
∴ k = 5
# h and k are the coordinates of the center of the circle
∴ The center of the circle is (-3 , 5)
# r² = 81 ⇒ take √ for both sides
∴ r = 9
∴ The length of the radius = 9 units
* The center of the circle is (-3 , 5) and the length of the radius is 9 units
The center of the circle is at (-3, 5), and the radius of the circle is 9, determined by the given equation (x + 3)^2 + (y – 5)^2 = 81.
Explanation:The student is asking about the equation of a circle and how to determine the coordinates of the center and the length of the radius. The given equation is (x + 3)2 + (y – 5)2 = 81. The general form of a circle's equation is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius.
To find the center of the circle, we look at the values h and k in the equation, which are the opposites of the constants added to x and y, respectively. Therefore, the center is at (-3, 5). To find the radius of the circle, we take the square root of the number on the right side of the equation. The square root of 81 is 9, so the radius is 9.

C)x2 + y2 − 6 = 0
D)4x2 + y2 − 1
The correct answer is:

[tex]|Huntrw6|[/tex]
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
x = ±6, y = 0
and x = 0 and y = ±12
And we need an equation which has above as an integer solutions.
So, it becomes,
Consider [tex]4x^2+y^2-144=0[/tex]
Put x = 0, we get
[tex]0+y^2=144\\\\y^2=144\\\\y=\sqrt{144}\\\\y=\pm 12[/tex]
Similarly,
Put y = 0,
[tex]4x^2+0=144\\\\4x^2=144\\\\x^2=\dfrac{144}{4}\\\\x^2=36\\\\\x=\pm 6[/tex]
Hence, Option 'D' is correct.

A shop sells T-shirts and shorts for the following prices: T-shirt=£3.25 Shorts=£4.99
A mother buys 3 T-shirts and a pair of shorts for her son. She pays with a £10 and a £5 note. With what coins could she be given change?
£15.00 - £14.76 = £0.24
I hope I help you..
The mother buys 3 T-shirts and a pair of shorts. The possible coins she could receive as change are £1, 50p, 20p, 2p, and 1p.
The cost of 3 T-shirts can be calculated as:
3 T-shirts= 3 x £3.25 = £9.75
The cost of a pair of shorts is £4.99
Therefore, the total cost of 3 T-shirts and a pair of shorts is £9.75 + £4.99 = £14.74
If the mother pays with a £10 note and a £5 note, she could receive coins like £1, 50p, 20p, 2p, and 1p as change.
What is the probability of getting a vowel (a successes) for the spinner? Compute P(3 successes) for 5 spins of the spinner
Answer:
What is the probability of getting a vowel (a success) for the spinner shown?
✔ 1/3
Suppose you spin the spinner 5 times.
✔ P(3 successes) means “the probability of getting a vowel on exactly 3 of the spins.”
Step-by-step explanation:
edg 2020
Using the binomial distribution, it is found that:
The probability of a success is of 1/3.P(X = 3) = 0.1646.For each spin, there are only two possible outcomes, either it is a vowel, or it is not. The result of a spin is independent of any other spin, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
The spinner has 3 regions, A, B and C, one of which is a vowel, hence p = 1/3 = 0.3333.There will be 5 spins, hence n = 5.The probability of 3 successes is given by:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{5,3}.(0.3333)^{3}.(0.6667)^{2} = 0.1646[/tex]

find a9 in the arithmetic sequence with a1 = -2.75 and d = 0.25
Answer:
The ninth term is -0.75.
Step-by-step explanation:
Let's write the actual formula for this arith. seq.
It will have the general form a(n) = a(1) + (n-1)d, where a(1) is the first term, n is the term counter (1, 2, 3, .... ) and d is the common difference.
Here, a(n) = -2.75 + (n - 1)(0.25)
So the ninth term of this sequence is
a(9) = -2.75 + (9 - 1)(0.25
= -2.75 + 8(0.25)
= -2.75 + 2
= -0.75
The ninth term is -0.75.
Answer:
[tex]a_9=-0.75[/tex]
Step-by-step explanation:
The given sequence has the first term, [tex]a_1=-2.75[/tex] and d=0.25
The general formula for an arithmetic sequence is given by;
[tex]a_n=a_1+d(n-1)[/tex]
Since we want to find [tex]a_9[/tex], it means n=9
We substitute the given values into the formula to obtain;
[tex]a_9=-2.75+0.25(9-1)[/tex]
[tex]a_9=-2.75+0.25(8)=-0.75[/tex]
Hence, the 9th term is
[tex]a_9=-0.75[/tex]
At your construction job, you're standing on a ladder at ground level. First, you climb down 7 feet to see the basement. Then you climb up 22 feet to see the second floor. Later, you climb down 9 feet. How high above or below the ground are you?
7 feet below the ground
6 feet below the ground
9 feet above the ground
9 feet below the ground
6 feet above the ground
Final answer:
After descending 7 feet, ascending 22 feet, and descending 9 feet, the individual is 6 feet above the ground level.
Explanation:
The question involves a sequence of movements by an individual on a ladder at a construction site. To solve this, let's track each movement relative to the initial position at ground level.
The individual climbs down 7 feet to the basement, so they are now 7 feet below ground.Then they climb up 22 feet which brings them 15 feet above ground level (since they were originally 7 feet below).Finally, climbing down 9 feet from the second floor, they are now 6 feet above the ground level.Therefore, the individual is 6 feet above the ground after these movements.
Emma is 9 and one fourths Year’s old. How many months old is Emma?
She is 4 years an d3 months old
Answer:
111 months
Step-by-step explanation:
First, look at how many whole years old Emma is. Emma is 9 whole years old. 1 year consists of 12 months. So, multiply 9 [years] by 12 [months] to get 108. The number 108 is how many months are in 9 years. However, Emma is 9 months and 1/4 years old.
To find out how many months 1/4 of a year is, multiply 1/4 [year] by 12 [months] . 12 is the same as 12/1, so multiply the numerators and denominators of 1/4 and 12/1
1 x 12 = 12
4 x 1 = 4
12/4 = 3
Therefore, 1/4 year is 3 months. Now, add 108 months and 3 months to get 111 months. Therefore, Emma is 111 months old.

Find the volume of a rectangular prism with the following dimensions. Length: 4yd width: 5 ft height: 11ft volume =
Answer:
660 ft³
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated using the formula
V = lbh ( l is length, b is breadth and h is height )
The dimensions must be in the same units, thus we need to change length into feet.
l = 4 × 3 = 12 ft ( 1 yard = 3 feet )
b = 5 ft and h = 11 ft
V = 12 × 5 × 11 = 660 ft³
Final answer:
Convert the length from yards to feet, then calculate the volume by multiplying length, width, and height to get 660 cubic feet.
Explanation:
To find the volume of a rectangular prism, you multiply the length, width, and height together. However, notice that in the problem the lengths are not all in the same units; the length is given in yards and the width and height in feet. First, we need to convert yards to feet so that all dimensions are in the same units, using the conversion factor that 1 yard is equal to 3 feet.
After converting, the length will be:
4 yd = 4 x 3 ft = 12 ft
Then you can calculate the volume:
Volume = length x width x height
= 12 ft x 5 ft x 11 ft
= 660 cubic feet

If a sample proportion is 0.26 which of the following is most likely the range of possible values that best describes an estimate for the population parameter
Answer: (0.15,0.37)
Step-by-step explanation:
did the quiz
The range of possible values that best describes the estimate for the population parameter is [0.16, 0.38]. Therefore, the correct answer is option D.
Given that, a sample proportion is 0.26.
In statistics, the sample proportion is an estimate for the population parameter. When given a sample proportion, the range of possible values that best describes the estimate for the population parameter is typically the 95% confidence interval for the sample proportion. The 95% confidence interval states that if the same sampling procedure is repeated on many samples, then 95% of the confidence intervals constructed this way will contain the true population parameter.
The 95% confidence interval for a sample proportion is given by [p-1.96√(pq/n), p+ 1.96√(pq/n)], where p is the sample proportion, q is the complement of the sample proportion (q = 1 − p), and n is the sample size.
In this case, the sample proportion given is 0.26, and so p = 0.26, q = 0.74, and the sample size can be assumed to be large (n ≥ 30). Substituting these values into the 95% confidence interval equation yields the range of possible values that best describes the estimate for the population parameter: [0.16, 0.38].
Therefore, the correct answer is option D.
