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
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.

Your Nana gives you $50 for making all A’s/B’s on your last report card. You have been eying a new pair of Crocs + their fancy charms which total to $65. However, Crocs is running a sale for 30% off your total purchase. Do you have enough money to FINALLY get yourself those new Crocs?
Please have an explanation I will give you BRAINLIEST
Answer:
Yes you have enough money because with the dicound the crocs are $45.50
Step-by-step explanation:
u have $50 the crocs is $65 but have 30% off
$65 with 30% off is $45.50
Answer:
YAY, you can buy the Crocs!
Step-by-step explanation:
First we divide $65/100% to find one percent.
1% = 0.65
100% (original price) - 30% (sale) = 70% --> so the Crocs cost 70% their original price.
0.65 (1%) x 70 = $45.50 (final price of Crocs)

geometry right triangle
Answer:
m<F= 44 degrees
length FH= 14.50 which would be 15
length GF= 20.15 which would be 20
perimeter= 48.65 which would be 49
Step-by-step explanation:
I took 90-46 to find F
Used tan46= x/14 to find FH
Used cos46=14/y to find GF
( it doesn't matter what variable you use)
Then added 14.50+14+20.15

A plant inspector takes a random sample of six month old seedlings from a nursery and measures their heights to the nearest mm .
Answer:
48
Step-by-step explanation:
Solve by elimination:
4x + 4y = 4
Answer:
x=−y+1
Step-by-step explanation:
Let's solve for x.
4x+4y=4
Step 1: Add -4y to both sides.
4x+4y+−4y=4+−4y
4x=−4y+4
Step 2: Divide both sides by 4.
4x = −4y+4
4 = 4
x=−y+1

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

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.

Answer:
Volume of the cylinder is 588π cm³ Or 1846.32 cm³
Step-by-step explanation:
Area of a cylinder is given by the formula,
Volume = πr²h
Here, r = Radius of the circular base
h = Height of the cylinder
From the picture attached,
Radius of the given cylinder = 7 cm
Height of the cylinder = 12 cm
By substituting these values in the formula,
Volume of the cylinder = π(7)²(12)
= 588π cm³
≈ 1846.32 cm³
Therefore, volume of the cylinder is 588π cm³ Or 1846.32 cm³.
An arithmetic sequence is given below.

Write an explicit formula for the n^th term a(n).
help me understand this plzz, no file just answer
Answer:
a(n)= a + (n - 1)d
a(n) = 17 - 3n
Step-by-step explanation:
14, 11, 8 , 5 , ...
The given sequence above is an Arithmetic sequence and the explicit formula is given as:
a(n) = a + (n - 1)d
Where
a = First term = 14
n = number of terms
d = common difference
The common difference =
Second term - First term or Third term - Second term
= 11 - 14 or 8 - 11 or 5 - 8
= -3
Therefore, the explicit formula for the nth term a(n) is written as:
a(n) = 14 + (n - 1)-3
a(n) = 14 -3n + 3
a(n) = 14 + 3 - 3n
a(n) = 17 - 3n
The explicit formula a(n) =
a(n) = 17 - 3n
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.
