The width of a rectangle is the length minus 6 units the area of the rectangle is 27 units
Answer:
length = 9 units
Step-by-step explanation:
l = length
n - 6 = width
A = n(n - 6)
A = n² - 6n
27 = n² - 6n
n² - 6n - 27 = 0
(n + 3)(n - 9) = 0
n = -3, n = 9
length must be 9 because it cannot be a negative value

There are many cylinders with radius 6 meters. Let hhh represent the height in meters and VVV represent the volume in cubic meters.
Write an equation that represents the volume VVV as a function of the height hhh. Use the symbol for \piππ.
VVV = _______?
Answer:
Step-by-step explanation:
VVV = πr²(hhh) = 36π(hhh)
The equation that represents the volume of the cylinder is 36πhhh m³.
What is a cylinder?A cylinder is a three-dimensional object. It is a prism with a circular base.
volume of a cylinder = πr²h

If you deposit Tsh 4000 into an account paying 9% annual interest compound monthly ,low long until there is Tsh 10000 in the account?
Answer:
It will take 10.63 years.
Step-by-step explanation:
Giving the following information:
Present value (PV)= $4,000
Future Value (FV)= $10,000
Interest rate (i)= 9% annual compounded
To calculate the time required to reach $10,000, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= number of years
n= ln(10,000 / 4,000) / ln(1.09)
n= 10.63
It will take 10.63 years.

Sara needs one third of a yard of ribbon to make a bow. She has 10 yards of ribbon. How many bows can she make?
Answer:
30 bows
Step-by-step explanation:
To find how many bows she can make, divide 10 by 1/3
10 / (1/3)
= 30
So, Sara can make 30 bows
Answer:
30
Step-by-step explanation:
If she needs just one third then she can make three ribbons out of a yard. so you multiply 3 by the number of yards she has so:
3 x 10 = 30
what’s the equation for this graph?
Answer:
y=-3x+2
Step-by-step explanation:
as x goes up on y goes down 3
slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2
The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of fuel changes as a function of distance flown is f(x)=−0.9x+665, where x represents miles flown, and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?
Given:
The function that represents how the amount of fuel changes as a function of distance flown is
[tex]f(x)=-0.9x+665[/tex]
where x represents miles flown, and f(x) represents the amount of fuel remaining.
To find:
The rate of change for this scenario.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope or rate of change and b is the y-intercept.
We have,
[tex]f(x)=-0.9x+665[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=-0.9[/tex]
Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

Find the measure of 14x+7+44+9x+3=180?
61° is the measure of <STW
How to find the measure of <STW?To solve this problem, we need some angle geometry knowledge
Given: <SRT = 44°, <RST = 9x+3, <RTW = 14x+7
<RTW = <SRT + <RST (exterior angle of a triangle is equal to the sum of opposite interior angles)
14x+7 = 44 + 9x+3
14x -9x = 44+3-7
5x = 40
x = 40/5 = 8
<STW + <RTW = 180 (sum of angles on a straight line)
<STW = 180 - <RTW
<STW = 180 - (14x+7)
Substitute x = 8:
<STW = 180 - (14(8) +7)
<STW = 180- 119 = 61°
Therefore, the measure of <STW is 61°
