Answer:

The length of the hypotenuse is: 45 yards

Step-by-step explanation:

Given

a=27 yd

b=36 yd

To Determine

Hypotenuse = c

Pythagorean Theorem

For a right-angled triangle with sides a, b, and c is defined as:

[tex]c=\sqrt{a^2+b^2}[/tex]

as

a=27

b=36

so substituting a=27, b=36

[tex]c=\sqrt{27^2+36^2}[/tex]

[tex]c=45[/tex] yards

Therefore, the length of the hypotenuse is: 45 yards

Step-by-step explanation:

A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles. The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles

Whiskers function in a box and whisker plot represent the interquartile range. Therefore, option A is the correct answer.

A special kind of graph called a box and whisker plot is used to display the distribution of groupings of numerical data. It displays the median—the average value of the numbers in your data—as well as the lowest and greatest values as well as the quartiles, which divide the data into four equally-sized groups.

The whiskers are the two lines that extend outside the box and run from the minimum to the lower quartile (the box's beginning) and from the higher quartile (the box's end) to the maximum value.

Therefore, option A is the correct answer.

Answer:

Jane spend 4 hours in a day sleeping, and 28 hours in a week.

Step-by-step explanation:

In 1 day, there are 24 hours. 24 multiplied by 1/6 is 4. I know this because 24 x 1/6 = 24/1 x 1/6 = 24/6 = 4/1 = 4.

In 1 week, there are 168 hours. 1/6 multiplied by 168 is 28. I know this because 168 x 1/6 = 168/1 x 1/6 = 168/6 = 28/1 = 28

Further explanation

Answer and explanation:

The equation y=19x+350 representing the total cost for the banquet hall based on number of people attending has both dependent and independent variables.

The independent variable is x which represents the number of people attending(each person costs $19) and therefore determines the total cost y which will be the cost of the banquet hall given number of people attending x

If we make an illustration with this equation, we could plug in a number of attendants x = 200 and then observe the total cost of the banquet hall y

If x=200

y=19x+350

y= 19×200+350

y= 3800+350

y= $4150

Therefore total cost of banquet hall if there are 200 guests at the banquet hall =$4150

The total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.

Given that,

The equation y = 19x+350 represents the relationship between the total cost,

In dollars, y, to rent a banquet hall for a party, and the number of people attending, x.

The y-intercept is 350 and represents the total cost to rent the banquet hall. The slope is 19.

We have to determine,

The cost per person attending.

According to the question,

The equation y = 19x+350 representing the total cost for the banquet hall based on the number of people attending has both dependent and independent variables.

The independent variable is x which represents the number of people attending(each person costs $19).

Therefore,

To determine the total cost y which will be the cost of the banquet hall given the number of people attending x.

Then, the total cost of the banquet hall y is,

[tex]y=19x+350\\\\y= 19\times200+350\\\\y= 3800+350\\\\y= 4150[/tex]

Hence, the total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.

Answer:

£6,910.70

Step-by-step explanation:

The computation of the amount invested is given below:

As we know that

Amount = Principal × (1 + rate of interest)^number of years

£8000 = Principal × (1 + 0.05)^3

£8000 = Principal × 1.05^3

£8000 = Principal × 1.157625

So, the principal amount is

= £8000 ÷ 1.157625

= £6,910.70

Answer:

It will cost $12.5 per person to charter a bus for 36 passengers

Step-by-step explanation:

The cost per person c of chartering a tour bus  varies inversely as the number of passengers  n.

We can write:

[tex]c\:\alpha \:\frac{1}{n} \\c=\frac{k}{n}[/tex]

where k is constant of proportionality

We are given when c = 22.50, n = 20

We need to find c when n = 36

First using c = 22.50, n = 20 we will find k, the constant of proportionality

[tex]c=\frac{k}{n}\\22.50=\frac{k}{20}\\k=22.50 \times 20\\k=450[/tex]

So, we get k = 450

Now, we will find c when n = 36

[tex]c=\frac{k}{n}\\c=\frac{450}{36}\\c=12.5[/tex]

So, we get the value of c: c = 12.5

Therefore, It will cost $12.5 per person to charter a bus for 36 passengers

Answer:

D) 57.5°

Step-by-step explanation:

As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.

Pythagoras Theorem = [tex]c^{2}[/tex] = [tex]a^{2} + b^{2}[/tex]

a = 7 and b = 11

[tex]a^{2}[/tex] = 49

[tex]b^{2}[/tex] = 121

Plugging in the values, we will get:

[tex]c^{2}[/tex] = 49 + 121

[tex]c^{2}[/tex] = 170

c = [tex]\sqrt{170}[/tex]

To calculate the unknown angle B, we can use law of sine.

Law of sine = [tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]

So,

[tex]\frac{c}{sinC}[/tex] = [tex]\frac{b}{sinB}[/tex]

[tex]\frac{\sqrt{170} }{sin90}[/tex] =  [tex]\frac{11}{sinB}[/tex]

Sin90 = 1

sinB = [tex]\frac{11}{\sqrt{170} }[/tex]

B = [tex]sin^{-1}[/tex] ([tex]\frac{11}{\sqrt{170} }[/tex])

B = 57.5°

Xavier rode his bicycle for a total of 18.25mi in one week.

Answer: 17%

Step-by-step explanation:

Last year:

Number of boys = 150 boys

Number or girls = 150 girls.

Total = 300 students

This year:

Number of boys = 150 + (24% × 150)

= 150 + (0.24 × 150)

= 150 + 36

= 186

Number or girls = 150 + (10% × 150)

= 150 + (0.1 × 150)

= 150 + 15

= 165

Total students = 186 + 165 = 351

Percentage increase = (351 - 300) / 300 × 100

= 51 / 300 × 100

= 17%

Answer:

Thats wrong

Step-by-step explanation:

Find new values:

150(1+0.24)=\color{green}{186}
