What type of study would you conduct if you wanted to know how many hours a week on average students at your school spend on homework? Explain your reasoning.
Answer:
In order to get the number of hours spent by the students on homework, a survey would be conducted where information would be collected from the students.
Step-by-step explanation:
In order to acquire the information directly from the users which cannot be measured otherwise, surveys are the best option. These provide an appropriate way of reaching out to large masses at a small-time with little or no prior investment.
A rowing team rowed 120 kilometers while going with the current in the same amount of time as it took to row 20 kilometers going against the current. The rate of the current was 10 kilometers per hour. Find the rate of the rowing team in still water.
Answer:
100/x+6=20/x-6
100x-600=20x+120
80x=720
x=9 miles an hour as the rowing teams' rate in still water

Answer:
D
Step-by-step explanation:
Answer:
the answer is d
Step-by-step explanation:
we can use point-slope form to find this answer.
first, make this equation
y-y 1=m(x-x1)
y-4=-6(x-1)
m=-6 because you can use slope intercept form to find the slope (as the name states lol)
then just distribute!!
y-4=-6x+6
add four to both sides
y=-6x+10
whoops, i did a little too much the answer is in bold!!!
good luck!! hope this helped! <3
Olivia used colored ribbon for a craft project. She used 1/6 of a yard of green, 1/3of a yard of red, and 1/4 of a yard of yellow. Which ribbon is the longest? *
Answer: Red ribbon.
Step-by-step explanation:
When it comes to fractions, if all the fractions being compared have the same numerator, the fraction with the smallest denominator is the largest.
In this question, all the fractions have a numerator of 1 so the longest one will be the one with the smallest denominator which is 1/3. The red ribbon is the longest.
Another way is to convert them to percentages:
1/6 * 100% = 16.7%
1/3 * 100% = 33.3%
1/4 * 100% = 25%
Red ribbon is again the largest.

3. Mrs. Sinclair is finding the selling price of a pair of $40
skates with a 30% markup. Find her mistakes and correct it.
Answer:
Selling price : $52
Step-by-step explanation:
First, find 30% out of 40.
x= (40)(30)=1200/ 100= 12
x=12
Add 30% to the original selling price.
So then you add $12 to $40 to get $52.

A 3 digit number is such that twice the hundreds digit is more than the tens digit by 2.The digit is thrice the hundreds digit.When the digits are reversed, the number is increased by 594.Find the number.
Answer:
The number is -341
Step-by-step explanation:
Let the three digit number be represented as 100a+10b+c
Given
2a -b = 2 ---(1)
a = 3c ----(2)
100a+10b+c - 100c -10b -a = 594
99a -99c = 594 ---(3)
From 2 & 3 , we get -
99*a - (99*3*a) = 594
99*2 a = 594
a = -3
a = 3c, c = -1
2*-3 -b = 2, b = -4
Number is -341

A plane travels a distance of 21,000 kn in a time of 3.2 hours what is its average speed rounded to the nearest whole number
Answer:
6563kmph
Step-by-step explanation:
take 21,000 divided by 3.2 hours to get the speed
21,000/3.2 = 6562.5
It says to round 6562.5 to the nearest whole number so its 6563

Answer: 32 and 42
Step-by-step explanation:
5j +12
j= 4
j = 6
5(4) + 12
5 times 4 = 20
20 + 12 = 32
5(6) + 12
5 times 6 = 30
30 + 12 = 42

Write 10x² + 3x -2=-1 in the form a(x+h)²+k clearly stating
the turning point or vertex.
Y intercept
The roots of the equation
Answer:
Below in bold.
Step-by-step explanation:
10x² + 3x -2 = -1
10x^2 + 3x - 1 = 0 Taking 10 out from the first 2 terms:-
10(x^2 + 0.3) - 1 = 0 Completing the square:
10[(x + 0.15)^2 - 0.15^2] - 1 = 0
10[(x + 0.15)^2 - 0.0225] - 1 = 0
10(x + 0.15)^2 - 0.225 - 1 = 0
10(x + 0.15)^2 - 1.225 = 0 is vertex form.
The vertex (turning point is at (-0.15, -1.225).
y- intercept is at the point where x = 0,
- that is at y = 10(0.15)^2 - 1.225 = -1
So at (0, -1).
Solving for x:
10(x + 0.15)^2 - 1.225 = 0
(x + 0.15)^2 = 0.1225
x + 0.15 = +/- sqrt 0.1225
x = -0.15 +/- sqrt 0.1225
The roots are -0.5, 0.2
