Answer:

PR = 288.75 feet

Step-by-step explanation:

There are two triangles that we need to consider:
ΔPRE and ΔPOC

These triangles are similar since
m∠PRE = m∠POC = 90°
∠PRE ≅ ∠POC

∠RPE ≅  ∠OPC (common angle)

AA Similarity theorem..
If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.  

∴ ΔPRE ≅ ΔPOC

If two triangles are similar, the ratios of the corresponding sides must be equal

⇒ [tex]\dfrac{PO}{PR} = \dfrac{OC}{PE}\\\\[/tex]    (1)

PO = PR + RO
PR is the width of the river that is to be determined
Let PR = x

Then
PO = x + 165

OC = 330, RE = 210

[tex]\dfrac{PO}{PR} = \dfrac{OC}{PE}\\\\\Rightarrow \dfrac{x + 165}{165} = \dfrac{330}{210}\\\\[/tex]

Left side:
[tex]\dfrac{x+165}{x} = \dfrac{x}{x} + \dfrac{165}{x} = 1 + \dfrac{165}{x}[/tex]

Simplify  [tex]\dfrac{330}{210}[/tex]   by dividing both numerator and denominator by 30

=>
[tex]\dfrac{330}{210} = \dfrac{11}{7}\\\\[/tex]

Therefore
[tex]\dfrac{PO}{PR} = \dfrac{OC}{PE}\\\\\Rightarrow 1 + \dfrac{165}{x} = \dfrac{11}{7}\\[/tex]

Subtract 1 from both sides:
[tex]\dfrac{165}{x} = \dfrac{11}{7} - 1\\\\\dfrac{165}{x} = \dfrac{4}{7}\\\\[/tex]

Cross-multiply
[tex]165 \times 7 = 4x\\\\\Rightarrow 4x = 165 \times 7\\\\\Rightarrow x = \dfrac{165 \times 7 }{4} = 288.75\;feet[/tex]

Answer:

(a) 44%

(b) 32%

Step-by-step explanation:

(a) In order to find the percentage of students that prefer comedies, we can add up divide the sum of the total number of students who prefer comedies (Twice/month or less + Thrice/month or more) by the total number of students.  

Then, we can multiply this number by 100 to find the percentage:

[tex](\frac{45+21}{150})*100\\ (\frac{66}{150})*100\\ 44[/tex]

(b) To find the percentage of students who visit the movies three times a month or more, we can divide the sum of the total number of students who visit the movies three times a month or more by the total number of students.

Like before, we can multiply this number by 100 to find the percentage:

[tex](\frac{21+27}{150})*100 \\(\frac{48}{150})*100\\ 32[/tex]

timer--;  //This statement uses the auto-decrement operator to decrease the value of the variable timer by 1.

The auto-decrement operator -- is used to decrease the value of a variable by 1. In this case, the variable is called timer. The statement which uses the auto-decrement operator is timer--;. This statement will take the current value of the timer variable and decrease it by 1. For example, if the current value of timer is 5, the statement timer--; will decrease the value to 4. This is a very useful and efficient way to decrease a variable's value by 1. It is also much shorter than having to write out a statement such as timer = timer - 1;. The auto-decrement operator can be used with other types of variables as well, such as strings or characters.

On solving the provided question, we can say that the equations are 3x+4y=6 and 8x-4y=5 => x = 1 and y = 3/4

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

Step-by-step explanation:

(a)

let ∠ QRS = x then ∠ PQR = x and

∠ QPS = [tex]\frac{6}{7}[/tex] x and ∠ PSR = [tex]\frac{4}{7}[/tex] x

the sum of the 4 angles in a quadrilateral = 360°

sum the 4 angles and equate to 360

x + x + [tex]\frac{6}{7}[/tex] x + [tex]\frac{4}{7}[/tex] x = 360 ( multiply through by 7 to clear the fractions )

7x + 7x + 6x + 4x = 2520

24x = 2520 ( divide both sides by 24 )

x = 105

then

∠ QRS = 105° , so

∠ PSR = [tex]\frac{4}{7}[/tex] × 105° = 4 × 15° = 60°

∠ QPS = [tex]\frac{6}{7}[/tex] × 105° = 6 × 15° = 90° ← a right angle

Answer:

Step-by-step explanation:

To calculate the rate at which the water level drops, we need to find the volume of water being lost per second and convert that to a height change. The volume of water being lost is given as 0.05 liters per second. The volume of a cylinder with height h and radius r is given by the formula:

V = πr^2h

We can rearrange this formula to solve for h:

h = V / (πr^2)

Substituting the given values, we get:

h = 0.05 / (π * 20^2) = 0.05 / (π * 400) = 0.05 / 1257.0796

So the rate at which the water level is dropping is approximately 0.04 cm per second.

Answer:

y = x + 1

Step-by-step explanation:

Since we have two points, we can find the equation of the line in slope-intercept form or y = mx + b, where m is the slope and b is the y-intercept.

We can find the slope using the slope formula, which is:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where y2 and x2 are one point on the line and y1 and x1 are the other point on the line:

Thus, we have:

[tex]m=\frac{7-26}{6-25}\\ m=\frac{-19}{-19}\\ m=1[/tex]

Now that we have the slope, we choose one of the points and plug in the slope to find the y-intercept:

Supplementary angles are two angles that equal 180 degrees. An angle is 180 degrees when it's a straight line. As you see, the line with E, A, P, and B is a straight line, making A and B supplementary.

Answer: Supplementary angles because the 2 angles when they are joined they both add up to 180 degrees

Step-by-step explanation:

The measures of the angles are:

n = q = j = 57°

m = l = p = k = 123°

Remember that vertical angles have the same measure, then:

n = 57°

And if the two horizontal lines are parallel, then the values in the correspondent quadrants are the same ones, then:

q = 57°

j = 57°

And adjacent angles add up to 180°, them:

57° + m = 180°

m = 180° - 57°

m = 123°

Then:

m = l = p = k = 123°

With a constant speed Robert took 20 minutes paddle.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, Robert paddled at a constant speed and travels 3/4 of a mile in 15 minutes.

We know that, Speed = Distance/Time

Speed = 3/4 ÷15/1

= 3/4 × 1/15

= 1/20 miles per minutes

Now, distance = 1 mile and speed =1/20 miles per minutes

1/20 = 1/Time

Time = 20 minutes

Therefore, with a constant speed Robert took 20 minutes paddle.

The size input which ABC's computer can execute in one minute for each algorithm for the following growth rates are given below:

For a growth rate of "n", it means the execution time increases linearly with the size of the input. In this case, XYZ's computer takes 1 minute to execute an input size of "n".

Company ABC claims that their computer is 100 times faster, so they can execute an input size of 100n in one minute.

For a growth rate of "2^n", it means the execution time increases exponentially with the size of the input.

In this case, if we double the input size, the execution time increases two times. So, if XYZ's computer takes 1 minute to execute an input size of "n", it would take 2 minutes to execute an input size of "2n".
