Answer:
6 * 4/15
Well you have this and we can make it multiply like
6/1 * 4/15
So you just multiply normally, with the same for numerator and denonminator
So 6*4=24
1*15=15
So 24/15
24/15 is 1 9/15 in mixed
1 9/15 can be simplified so
1 3/5
So 1 3/5 is the simplest form
\(\large\underline{\sf{Solution-}}\)
\( \sf \: 6 \: of \frac{4}{15} \\ \)
\( \sf \: = 6 \times \frac{4}{15} \\ \)
\(\sf \: = \frac{6 \times 4}{15} \\ \)
\(\sf \: = \frac{24}{15} \\ \)

find the equation of the axis of symmetry for this function. f(x)=-2x^2-3x+6
PLEASE HELP
Answers
The equation of the axis of symmetry of the quadratic function f(x) = -2x^2 - 3x + 6 is x = -b/2a, where a and b are coefficients of the quadratic function.
A quadratic function is a function of form f(x) = ax^2 + bx + c, where a, b, and c are constants. The graph of a quadratic function is a parabola, which is symmetric about a vertical line called the axis of symmetry.
To find the axis of symmetry for the given quadratic function f(x) = -2x^2 - 3x + 6, we first identify the coefficients a and b. In this case, a = -2 and b = -3.
Then we use the formula x = -b/2a to find the x-coordinate of the vertex, which is the point on the axis of symmetry. Plugging in the values of a and b, we get:
x = -(-3)/(2*(-2)) = 3/4
Therefore, the equation of the axis of symmetry is x = 3/4.

The perimeter first figure that is made of a square and equilateral triangle is 52 cm.
What exactly are squares?
A square is a two-dimensional planar shape with four equal sides and four 90-degree angles. The features of a rectangle are similar to those of a square, but the distinction is that a rectangle has just its opposing sides equal.
A square's most significant qualities are
The four inner angles are 90 degrees.The four sides of the square are congruent, or equal.The square's opposing sides are parallel.The diagonals of the square intersect at 90°.The square's two diagonals are equal to each other.The diagonal of a square is divided into two isosceles triangles.
Square area=(side)²
Square perimeter=4*side
Now,
For first figure given that
sides of square are 14 cm in length
and length of side of equilateral triangle are=5 cm
but for finding perimeter of the figure only 3 sides of square and 2 sides of triangle are needed.
So, perimeter=3*14+2*5

Rory is at the local mall and her favorite type of jeggings are on sale. The jeggings are now
priced at $7 per pair, tax free. She has $27 with her, but she needs to have $6 leftover to
spend on a movie theater ticket.
Which inequality represents how many pairs of jeggings Rory can buy, where / represents
the number of jeggings?
Answers
Answer:
j ≤ 3
Step-by-step explanation:
Since she has $27 with her and needs a balance if $6, the amount of money she can spend on buying the jeggings will be $27-$6 = $21
This means that she has $21 to spend on buying the jeggins
From the question, one jeggings cost $7, so the maximum number of jeggings she can buy is 21/7 = 3
So the inequality that represents this will be;
j ≤ 3
This is because she can decide to buy less than 3, but never can she buy more than 3 because of her budgetary constraints

Answers
Using the z-distribution, the 90% confidence interval for the difference of proportions is given by: (-0.0534, 0.0434).
What is the mean and the standard error for the distribution of differences?For each sample, the mean and the standard error are given as follows:
\(p_1 = \frac{30}{235} = 0.1277, s_1 = \sqrt{\frac{0.1277(0.8723)}{235}} = 0.0218\).\(p_2 = \frac{39}{294} = 0.1327, s_1 = \sqrt{\frac{0.1327(0.8673)}{294}} = 0.0198\).For the distribution of differences, they are given by:
\(\overline{p} = p_1 - p_2 = 0.1277 - 0.1327 = -0.005\).\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0218^2 + 0.0198^2} = 0.0294\)What is the confidence interval?The interval is given by:
\(\overline{p} \pm zs\)
In this problem, we have a 90% confidence level, hence\(\alpha = 0.9\), z is the value of Z that has a p-value of \(\frac{1+0.9}{2} = 0.95\), so the critical value is z = 1.645.
Hence the bounds of the interval are:
\(\overline{p} - zs = -0.005 - 1.645(0.0294) = -0.0534\)

Answers
C. True, because to use the Law of Sines, at least two sides must be known.
The Law of Sines is a trigonometric rule that relates the sides and angles of any triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
To use the Law of Sines, at least two sides and the angle opposite one of them (or two angles and one side) must be known.
Therefore, the statement "The Law of Sines can be used to solve triangles where three sides are known" is false, as it is not necessary to use the Law of Sines to solve a triangle where all three sides are known.
In summary, the correct answer is C. True, because to use the Law of Sines, at least two sides must be known.

Gravel is being dumped from a conveyor belt at a rate of 50 cubic feet per minute. it forms a pile in the shape of a right circular cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 20 feet high?
Answers
The height of the pile is increasing at a rate of approximately 0.397 feet per minute when the pile is 20 feet high.
To solve this problem, we need to use related rates. Let's start by drawing a diagram:
```
/\
/ \
/ \
/ \
/ \
/__________\
```
We know that the rate at which gravel is being dumped is 50 cubic feet per minute, so the volume of the pile is increasing at a rate of 50 cubic feet per minute. We also know that the base diameter and height of the cone are always equal, so we can call them both "r".
Let's use the formula for the volume of a cone to relate the rate of change of the volume to the rate of change of the height:
V = (1/3)πr^2h
Taking the derivative with respect to time t, we get:
dV/dt = (1/3)π(2rh)(dh/dt) + (1/3)πr^2(dh/dt)
Simplifying and plugging in the values we know:
50 = (1/3)π(2r*20)(dh/dt) + (1/3)πr^2(dh/dt)
Simplifying further:
50 = (2/3)πr^2(dh/dt)
dh/dt = 50/[(2/3)πr^2]
We still need to find the value of "r" in order to calculate the final answer. We know that the base diameter and height are equal, so the radius is half of the base diameter, which is also equal to the height. Therefore, when the pile is 20 feet high, the radius is also 20 feet.
Plugging in the values:
dh/dt = 50/[(2/3)π(20^2)]
dh/dt ≈ 0.397 feet per minute
Therefore, the height of the pile is increasing at a rate of approximately 0.397 feet per minute when the pile is 20 feet high.
Gravel is being dumped from a conveyor belt at a rate of 50 cubic feet per minute, forming a right circular cone with equal base diameter and height. When the pile is 20 feet high, let's find out how fast the height is increasing.
Since the base diameter and height are always equal, the radius of the cone base (r) is half the height (h). Therefore, r = h/2. The volume (V) of a cone is given by the formula V = (1/3)πr^2h.
Substitute r with h/2: V = (1/3)π(h/2)^2h.
Now differentiate both sides with respect to time (t) to find dV/dt and dh/dt (rate of height increase):
dV/dt = (1/3)π (h^3/4) dh/dt.
We know dV/dt is 50 cubic feet per minute, and we want to find dh/dt when h = 20 feet:
50 = (1/3)π (20^3/4) dh/dt.
Now, solve for dh/dt:
dh/dt = 50 / [(1/3)π(20^3/4)].
dh/dt ≈ 0.424 ft/min.
So, the height of the pile is increasing at approximately 0.424 feet per minute when the pile is 20 feet high.

3 Years Ago, You Have Started An Annuity Of 200 Per Months. How Much Money You Will Have In 3 Years If The Interest On The Account Is 3% Compounded Monthly? $15.755.8 B $16,863.23 $17,636.45
Answers
The future value of the annuity is approximately $17,636.45.
An annuity is a series of equal payments made at regular intervals. In this case, you started an annuity of $200 per month. The interest on the account is 3% compounded monthly.
To calculate the amount of money you will have in 3 years, we can use the formula for the future value of an annuity. The formula is:
FV = P * [(1 + r)^n - 1] / r
Where:
FV is the future value of the annuity
P is the monthly payment ($200)
r is the interest rate per period (3% per month, or 0.03)
n is the number of periods (3 years, or 36 months)
Plugging in the values into the formula, we have:
FV = 200 * [(1 + 0.03)^36 - 1] / 0.03
Calculating this expression, we find that the future value of the annuity is approximately $17,636.45.
Therefore, the correct answer is $17,636.45.

at the mp donut hole factory, niraek, theo, and akshaj are coating spherical donut holes in powdered sugar. niraek's donut holes have radius $6$ mm, theo's donut holes have radius $8$ mm, and akshaj's donut holes have radius $10$ mm. all three workers coat the surface of the donut holes at the same rate and start at the same time. assuming that the powdered sugar coating has negligible thickness and is distributed equally on all donut holes, how many donut holes will niraek have covered by the first time all three workers finish their current donut hole at the same time?
Answers
Niraek will have covered 400 donut holes by the time all three workers finish their current donut holes at the same time.
The time it takes to coat a donut hole is directly proportional to the surface area of the donut hole.
The surface area of a sphere is given by the formula:
Surface Area = 4πr²
Here, r is the radius of the sphere.
Comparing the surface areas of the donut holes:
Niraek's donut hole: Surface Area = 4π(6²)
Theo's donut hole: Surface Area = 4π(8²)
Akshaj's donut hole: Surface Area = 4π(10²)
Now, let's find the LCM of the surface areas to determine the time it takes for all workers to finish:
LCM(144π, 256π, 400π) = 57600π mm²
This means that it will take the same amount of time for all three workers to finish their current donut holes when they have covered a total surface area of 57600π mm².
Number of donut holes = (Total surface area) / (Surface area of Niraek's donut hole)
= (57600π mm²) / (144π mm²)
= 57600 / 144
= 400
Therefore, Niraek will have covered 400 donut holes by the time all three workers finish their current donut holes at the same time.
