The height of the building is 71 meters.

We can solve this problem using the similar triangles. The height of the building can be determined by setting up the following proportion:

(the height of pole) / (length of pole's shadow) = (height of building) / (length of building's shadow)

Substituting the given values:

2.8 / 1.49 = (height of building) / 37.5

To find the height of the building, we can cross-multiply and solve for it:

(2.8 * 37.5) / 1.49 = height of building

Calculating the expression on the right side:

(2.8 * 37.5) / 1.49 ≈ 70.7013

Rounding to the nearest meter, the height of the building is approximately 71 meters.

option c is correct

The probability of washing dishes by me tonight will take between 15 and 16 minutes is 14.29%.

The term "uniform distribution" refers to a type of probability distribution in which the likelihood of each potential result is equal.

Let's consider, the lower limit for this distribution as a and the upper limit for this distribution as b.

The following formula gives the likelihood that we will discover a value for X between c and d,

\(P(c\leq X\leq d)=\frac{d-c}{b-a}\)

Given the time it takes me to wash the dishes is 11 minutes and 18 minutes. From this, a = 11 and b = 18.

Then,

\(P(15\leq X\leq 16)=\frac{16-15}{18-11}=0.1429=14.29\%\)

The answer is 14.29%.

Answer:

12709 balls

Step-by-step explanation:

Given

Dimension of Room = 15 ft by 20 ft by 10 ft

Diameter of Ball = 9.2 inches

Required

Determine the number of balls that can be occupied by the room

First, we need to calculate the volume of the room

This is done by multiplying the dimensions of the room

\(Volume = 15ft * 20ft * 10ft\)

\(Volume = 3000ft^3\)

Next, we calculate the volume of the ball.

The ball is a sphere.

So:

\(Volume = \frac{4}{3}\pi r^3\)

Where

\(r = \frac{1}{2} * Diameter\)

\(r = \frac{1}{2} * 9.2\)

\(r = 4.6\ in\)

So:

\(Volume = \frac{4}{3}\ * \frac{22}{7} * (4.6in)^3\)

\(Volume = 407.88419\ in^3\)

To calculate the number of balls, we then divide the volume of the room by volume of a ball

\(Balls = \frac{3000\ ft^3}{407.88419\ in^3}\)

Convert ft^3 to in^3

\(Balls = \frac{3000 * 1728in^3}{407.88419\ in^3}\)

\(Balls = \frac{3000 * 1728}{407.88419}\)

\(Balls = \frac{5184000}{407.88419}\)

\(Balls = 12709.4899167\)

\(Balls = 12709\) -- approximated

Hence, the room will contain 12709 balls

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

Answer:

556.5 cm²

Step-by-step explanation:

Area of trapezium :

Area = 1/2 (a + b)h

a = base length 1

b = base length 2

h = height

From the information given :

Distance between MN and PQ = Height, h = 21 cm

Base MN, a = 28 cm

Base PQ, b = 25 cm

Hence,

Area = 1/2 (28 + 25) * 21

Area = 1/2 (53) * 21

Answer:

30

Step-by-step explanation:

The area would have been 80*x=1600.

that means x=60. So, two pennant bases are 60.

That means one pennant base is 30.

Answer:

y = 360

Step-by-step explanation:

Given y is inversely proportional to x² then the equation relating them is

y = \(\frac{k}{x^2}\) ← k is the constant of proportion

To find k use the condition y = 10 when x = 3 , then

10 = \(\frac{k}{3^2}\) = \(\frac{k}{9}\) ( multiply both sides by 9 )

90 = k

y = \(\frac{90}{x^2}\) ← equation of proportion

When x = \(\frac{1}{2}\) , then

y = \(\frac{90}{(\frac{1}{2})^2 }\) = \(\frac{90}{\frac{1}{4} }\) = 90 × 4 = 360

The exponential equation that models Isabella's weekly sales, S(w) in dollars, w weeks after opening her shop can be written as:

S(w) = ab^w; where a is the initial sales in the first week, and b is the rate of increase per week as a decimal.

We know that her sales in the first week were $86, so a = 86. And we also know that her sales increased by 20% the following week, so her sales in the second week were 1.2 times her sales in the first week, or 1.2 x 86 = $103.2.

To find b, we can use the fact that her sales continued to increase at the same rate each week. That means that the ratio of her sales in any two consecutive weeks is the same. So we have:

S(w+1)/S(w) = 1 + b

103.2/86 = 1 + b

b = 0.2

So the exponential equation that models Isabella's weekly sales is:

S(w) = 86 x 1.2^w

Therefore, the equation S(w) = 86 x 1.2^w will give the sales in dollars for any number of weeks w after Isabella opened her shop.

Answer:

  24 square units

Step-by-step explanation:

There are a couple of ways you can figure the area of the frame:

__

The dimensions of the outer rectangle are twice the frame width plus the dimensions of the inner rectangle. That makes them 8 wide by 6 high. Then the difference of areas is ...

  A = (8)(6) -(6)(4) = 48 -24 = 24 . . . . square units frame area

__

The centerline of the frame is a rectangle with 1 unit greater length and width than the inner rectangle. It is 7 units by 5 units, so will have a perimeter of ...

  P = 2(L+W) = 2(7+5) = 24 . . . . units

Then the area of the frame is this length multiplied by the width of the frame:

  A = (24)(1) = 24 . . . . square units frame area

In the given question, we shall check the bag is underfilled at given level or not .

We can use the hypothesis testing, The Null and Alternative hypothesis are given as below :

H₀ : u = 411 : the bags are not underfilled

Hₜ : u < 411 : the bags are underfilled

Check it now using statistic Z-test and the test Statistic formula is given by

From given data we get, n= 19 ; M = 437 ; S.D = √ variance = √ 441 = 21

Including all of the above variables in formula

Given expansion:

\((x + y)^4\)

Therefore:

Substitute these values into the Binomial Series formula:

\(\implies \displaystyle (x+y)^4=x^4+\binom{4}{1}x^{4-1}y^1+\binom{4}{2}x^{4-2}y^2+\binom{4}{3}x^{4-3}y^3+\binom{4}{4}x^{4-4}y^4\)

\(\implies \displaystyle (x+y)^4=x^4+\binom{4}{1}x^{3}y+\binom{4}{2}x^{2}y^2+\binom{4}{3}xy^3+\binom{4}{4}y^4\)

\(\implies \displaystyle (x+y)^4=x^4+\frac{4!}{1!(4-1)!}x^{3}y+\frac{4!}{2!(4-2)!}x^{2}y^2+\frac{4!}{3!(4-3)!}xy^3+\frac{4!}{4!(4-4)!}y^4\)

\(\implies \displaystyle (x+y)^4=x^4+4x^{3}y+6x^{2}y^2+4xy^3+y^4\)

Therefore, the coefficients corresponding to the terms of the expansion are:

\(\boxed{\begin{minipage}{5cm} \underline{Binomial Theorem}\\\\$\displaystyle (a+b)^n=\sum^{n}_{k=0}\binom{n}{k} a^{n-k}b^{k}$\\\\\\where \displaystyle \binom{n}{k} = \frac{n!}{k!(n-k)!}\\\end{minipage}}\)

Given expansion:

\((x + y)^4\)

Therefore:

Substitute these values into the Binomial Theorem formula:

\(\displaystyle (x+y)^4=\sum^{4}_{k=0}\binom{4}{k} x^{4-k}y^{k}\)

The coefficient of each term is given by:

\(\displaystyle \binom{4}{k} = \frac{4!}{k!(4-k)!}\)

Therefore, to find the coefficients of the terms of the expansion, substitute k = 0 through 5 into the coefficient formula:

\(k=0 \implies \displaystyle \binom{4}{0} = \frac{4!}{0!(4-0)!}=1\)

\(k=1 \implies \displaystyle \binom{4}{1} = \frac{4!}{1!(4-1)!}=4\)

\(k=2 \implies \displaystyle \binom{4}{2} = \frac{4!}{2!(4-2)!}=6\)
