Last year at a certain high school, there were 150 boys on the honor roll and 150 girls
on the honor roll. This year, the number of boys on the honor roll increased by 24%
and the number of girls on the honor roll increased by 10%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).
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}
150(1+0.24)=186
150(1+0.06)=\color{blue}{159}

Last Year This Year
Boys 150 186
Girls 150 159

Jane spends about 1/6 of the day sleeping. How many hours in a day does Jane sleep? How many hours in a week?
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

The cost per person c of chartering a tour bus
varies inversely as the number of passengers
n. If it costs $22.50 per person to charter a
bus for 20 passengers, how much will it cost
per person to charter a bus for 36 passengers?
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
Cynthia invests some money in a bank which pays 5% compound interest per year.
She wants it to be worth over £8000 at the end of 3years.
What is the smallest amount to nearest pound she can invest?
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

What is the length of the hypotenuse?
C-
yards
Answer:
The length of the hypotenuse is: 45 yards
Step-by-step explanation:
Given
a=27 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

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 and represents the cost per person attending
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.

What is the function of the “whiskers” in a box and whisker plot?
A
They represent the interquartile range.
B
They link the interquartile range to the minimum and maximum.
C
They compare the lower quartile to the upper quartile.
D
They compare the median to the interquartile range.
Answer:
the answer should be c
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.
What is a box-and-whisker plot?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.

If a = 7 and b = 11, what is the measure of ∠B? (round to the nearest tenth of a degree) A) 32.5° B) 39.2° C) 50.5° D) 57.5°
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°
