Answer:

9.0 ft (nearest tenth)

Step-by-step explanation:

The chord is the base of an isosceles triangle with sides of the radius.

To calculate the approximate distance of the chord from the center of the circle, we need to find the height of this triangle.

[tex]\sf height=\sqrt{s^2-(\frac{b}{2})^2}[/tex]

(where s is the side length and b is the base length of an isosceles triangle)

Given:

[tex]\begin{aligned}\implies \sf height & =\sqrt{10.8^2-\left(\frac{12}{2}\right)^2}\\ & = \sqrt{116.64-36}\\ & = \sqrt{80.64}\\ & = 8.979977728...\\ & = 9.0\: \sf ft\:(nearest\:tenth) \end{aligned}[/tex]

Step-by-step explanation:

In the question we are given ,

And , we have to find the height of cylinder .

We know that ,

[tex]

\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow[/tex]

Our solution starts from here :

[tex] \longmapsto \: \pi \: r {}^{2} h = 225\pi[/tex]

Step 1 : Cancelling π with π :

[tex] \longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}[/tex]

Step 2 : Substituting value of radius which is 5 cm in the formula :

[tex] \longmapsto \: (5) {}^{2} \times h = 225[/tex]

[tex] \longmapsto \: 25h = 225[/tex]

Step 3 : Transposing 25 to right hand side :

[tex] \longmapsto \: h = \frac{225}{25} [/tex]

Step 4 : Cancelling 225 by 25 :

[tex] \longmapsto \: \red{\boxed{h = 9 \: cm}}[/tex]

The equation of the circle is (x + 3)² + (y + 5)² = 36. Then the correct option is B.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The center of a circle at (–3, –5) and a radius of 6 units. Then the equation will be given as

(x + 3)² + (y + 5)² = 6²

(x + 3)² + (y + 5)² = 36

Then the equation of the circle is (x + 3)² + (y + 5)² = 36.

Ian pay $10,890 in property tax every year if the assessed value of 55% of that amount and his state has a property tax rate of 0.088 option (c) is correct.

It is defined as the amount paid by the owner of the property such as land, buildings etc.

We have:

Lan's house and land have a market = $225,000

Assessed value = 55% ⇒ 0.55

Property tax rate = 0.088

We know the formula for property tax is given by:

Property tax = tax rate×assessed value×market value

Put the values in the above formula, we get:

Property tax = 0.088×0.55×225000

= $10,890

Thus, Ian pay $10,890 in property tax every year if the assessed value of 55% of that amount and his state has a property tax rate of 0.088.

Answer:

x + 8y - 35 = 0.

Step-by-step explanation:

The hypotenuse is the line joining A and C.

Slope = (4-5) / (3 + 5)

= -1/8.

Equation is:

y - 4 = -1/8(x - 3)

y - 4 = -1/8x + 3/8

1/8x + y - 35/8 = 0

x + 8y - 35 = 0

Using the z-distribution, as we have the standard deviation for the population, it is found that 8 stores must be analyzed.

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In this problem, we have an 82% confidence level, hence[tex]\alpha = 0.82[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.82}{2} = 0.91[/tex], so the critical value is z = 1.34.

The standard deviation for the population is of [tex]\sigma = 0.06[/tex], and we want a margin of error of M = 0.03, hence we solve for n to find the sample size needed.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.03 = 1.34\frac{0.06}{\sqrt{n}}[/tex]

[tex]0.03\sqrt{n} = 1.34 \times 0.06[/tex]

Simplifying by 0.03:

[tex]\sqrt{n} = 1.34 \times 2[/tex]

[tex](\sqrt{n})^2 = (1.34 \times 2)^2[/tex]

[tex]n = 7.2[/tex]

Rounding up, 8 stores must be analyzed.

Answer:

50 minutes

Step-by-step explanation:

Given:

[tex]\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}[/tex]

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

[tex]\implies \text{Monday + Wednesday = Total time practiced on piano for a week}[/tex]

Substitute the times in the equation

[tex]\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}[/tex]

Simplify the equation

[tex]\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

[tex]\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

[tex]\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}[/tex]

In mathematics, the term 'product' refers to the answer to a multiplication problem.

The product of the given expression is determined in the following steps given below.

[tex]\rm =\dfrac{\dfrac{2y}{y-3} }{\dfrac{4y-12}{2y+6}}\\\\\\=\dfrac{2y}{y-3}\times \dfrac{2y+6}{4y-12}\\\\= \dfrac{2y \times 2y + 2y \times 6}{y(4y-12)-3(4y-12)}\\\\=\dfrac{4y^2+12y}{4y^2-12y-12y+36}\\\\=\dfrac{4y^2+12y}{4y^2-24y+36}\\\\=\dfrac{4(y^2+3y)}{4(y^2-6y+9)}\\\\ =\dfrac{(y^2+3y)}{(y^2-6y+9)}\\[/tex]

Hence, the product of the expression [tex]\rm \dfrac{\dfrac{2y}{y-3} }{\dfrac{4y-12}{2y+6}}\\\\\\[/tex] is [tex]\rm \dfrac{(y^2+3y)}{(y^2-6y+9)}\\[/tex].

Answer: $2400

Step-by-step explanation:

$2225.50 x 1.2% =  $26.71 + $2225.50 =  $2252.21  - Year 1

$2252.21 x 1.2% = $27.03 + $2252.21 =  $2279.23  - Year 2

$2279.23 x 1.2% = $27.35 + $2279.23 =  $2306.58  - Year 3

$2306.58 x 1.2% = $27.68 + $2334.26 =  $2334.26  - Year 4

$2334.26 x 1.2% = $28.01 + $2362.27 =   $2362.27  - Year 5

$2362.27 x 1.2% = $28.35 + $2362.27 =  $2390.62  - Year 6

$2390.62 x 1.2% = $28.69 + $2390.62 =  $2419.31  - Year 7

$2419.31         x 1.2% = $29.03 + $2419.31 =  $2448.34  - Year 8

Parallelograms have 2 pairs of congruent, parallel sides, and opposite angles that are congruent.

If side KL = 31, then its opposite side, side MN, must also be 31.

If angle N = 119 degrees, then its opposite angle, angle L must also be 119 degrees.

Angle L and Angle K are on the same side of the parallelogram, which means that they are supplementary angles (add up to 180).

119 + K = 180

Angle K = 61 degrees

Both the median and the range changed, the correct option is A.

Median, in statistics, is the middle value of the given list of data, when arranged in an order.

The data set that contains the outlier is given as:

4, 14, 15, 15, 16, 16, 18, 19, 20, 20, 21

The minimum value of the data is: 4

The median or middle quartile i.e. [tex]\rm Q_2[/tex]  is the central tendency of the data and exists in the middle of the data.

The median is: 16

Also, the lower set of data is:

4,14,15,15,16

The lower quartile i.e. [tex]\rm Q_1[/tex]  is the median of the lower set of data.

The  lower quartile i.e. [tex]\rm Q_1[/tex] = 15

Similarly, the upper set of data is:

18, 19, 20, 20, 21

the upper quartile i.e. [tex]\rm Q_3[/tex]  is the median of the upper set of data.

upper quartile i.e. [tex]\rm Q_3[/tex] = 20

Also, the interquartile range is:

[tex]\rm Q_3-Q_1=20-15=5[/tex]

The maximum value of the set is 21.

Range = Maximum value-Minimum value =21 - 4 = 17

As we know that 4 is the outlier of the data as it is the smallest as compared to all the data points.

After removing the outlier the data set is:

14, 15, 15, 16, 16, 18, 19, 20, 20, 21

The minimum value of the set =14

The maximum value of set =21

Range = Maximum value-Minimum value =21-14 = 7
