Answer:
0.75gal.
Step-by-step explanation:
(4gal.) (2qt) - (3gal.) (3qt) =
the easiest way to solve this would be get everything in the same units,
lets make the qt to gallons
2qt = 0.5gal divide the volume value by 4
3qt = 0.75gal
(4gal.) + (0.5gal.) - (3gal.) + (0.75gal.)
= (4.5gal.) - (3.75gal.)
= 0.75gal.

A drum has a diameter of 20 inches and is 16 inches deep. Find the volume of this drum.
The volume of this drum is approximately
in³.
HELP QUICK!!!!
Answer:
[tex] \boxed{\rm \: Volume_{(Drum)} = 5024 \: in {}^{3} }[/tex]
Step-by-step explanation:
Given :
Diameter of a drum = 20 inchesDeep ( height ) of the drum = 16 inchesπ = 3.14To Find:
The volume of the drum.
Solution:
We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.
[tex] \boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}[/tex]
Where,
r = radiush = height (deep)π = 3.14The value of radius ain't given,but the diameter is given.We can use the formulae of radius.
[tex] \rm \: Radius = D/2[/tex]
D = diameterSubstitute the value of diameter:
[tex] \rm \: Radius = \cfrac{20}{2} = 10[/tex]
Hence,the radius is 10.
So we could now use the formulae of the volume of cylinder:
[tex] \rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h[/tex]
π = 3.14r =10 inh = 16 in[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]
[tex] \rm \: Volume_{(Drum)} = \pi(10) {}^{2} (16)[/tex]
[tex] \rm \: Volume_{(Drum)} =\pi100(16)[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600\pi[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600 \times 3.14[/tex]
[tex] \boxed{\rm \: Volume_{(Cylinder)} = 5024 \: in {}^{3}} [/tex]
Hence, we can conclude that:
The volume of this drum is 5024 in^3.
a car can travel 340 km with 17 litres of petrol. how much can I travel with 20 litres of petrol?
The car would travel a distance of 400 km using 20 litres of petrol
How to determine the distance travelled?The given parameters can be represented using the following scale ratio :
Scale = 340 km : 17 litres
For 20 litres of petrol, we have:
Distance : 20 = 340 km : 17
Express as fraction
Distance/20 = 340 km/17
Multiply both sides by 20
Distance = 400 km
Hence, the car would travel a distance of 400 km using 20 litres of petrol

Write the equation of the circle in general form. Show your work.
Answer:
x^2+2x+y^2−2y−7=0
Step-by-step explanation:
The method from converting to standard to general is very simple
this equation in standard form would be
(x+1)^2+(y-1)^2=9
This is because whatever the center of the circle is, you take the negative/positive version of that number
The center is at -1, 1. So it would flip to be put into the equation as 1, -1.
9 is the radius^2.
The radius is 3.
To convert to general form you just simplify
x^2+1+2x = (x+1)^2
y^2 + 1 -2y = (y-1)^2
x^2 - 2x + y^2 - 2y + 2 = 9
get the nine on the left side
x^2 -2x +y^2 - 2y 2 - 9 = 0
x^2+2x+y^2−2y−7=0

A) Describe the relationship among the lengts of the segments formed by the secant (DB) and secant (CB) . You may use words and/or an equation.
B) Suppose DB = 18 ft, AB = 3 ft, and CB = 10 ft. Find the lengt of CE. Show all your work.
Given the following parameters DB = 18 ft, AB = 3 ft, and CB = 10 ft. Therefore, The length of the CE is 4.6 ft.
What is Secant-secant rule?The secant-secant rule states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.
Mathematically:
(BA + AD)BA = (BE + EC)BE
Given the following parameters
DB = 18 ft, AB = 3 ft, and CB = 10 ft.
Substitute to check if we can find CE
(BA + AD)BA = (BE + CE)BE
(3+ 15) x 3 = (10 + CE ) x 10
18 x 3 = 100 + 10CE
54 = 100 + 10CE
CE = 4.6
Therefore, The length of the CE is 4.6 ft.

Step-by-step explanation:
For 10π, we can simplify π into 3.14 for an approximate amount. 3.14*10=31.4
For the square root of ten, we can estimate it's between 10 and 11 since 10 squared is 100 and 11 squared is 121.
Answer:
See explanation
Step-by-step explanation:
First, we have to put the expressions into numbers. For the square root of 101, it doesn't divide evenly into any whole number. We do know that 10^2 is 100, and 11^2 is 121. That means the square root of 101 is between 10 and 11. Pi is equal to 3.14, so we just multiply 10 by 3.14. If we do this, we get 31.4. From here we can rank the numbers in order from greatest to smallest.
31.4 (10pi) is greater than
The square root of 101 which is greater than

Without using a calculator, determine the number of real zeros of the function
f(x) = x3 + 4x2 + x − 6.
PLEASE HELP!!!
The number of real zeros of the function f(x) = x3 + 4x2 + x − 6 is 3
How to determine the number of real zeros?The equation of the function is given as:
f(x) = x^3 + 4x^2 + x - 6
Expand the function
f(x) = x^3 + 5x^2 - x^2 + 6x - 5x - 6
Reorder the terms of the function
f(x) = x^3 + 5x^2 + 6x - x^2 - 5x - 6
Factor the expression
f(x) = x(x^2 + 5x + 6) -1(x^2 + 5x + 6)
Factor out x -1
f(x) = (x^2 + 5x + 6)(x -1)
Expand
f(x) = (x^2 + 3x + 2x + 6)(x -1)
Factorize
f(x) = [x(x + 3) + 2(x + 3)](x - 1)
Factor out x + 2
f(x) = (x + 3)(x + 2)(x- 1)
The function has been completely factored;

Write the equation of the line in slope-intercept form.
The equation of the line in slope-intercept form is ___
Answer:
y = 1/40x + 20
Step-by-step explanation:
Slope-intercept equation format:
y = mx + b
m = slope/ gradient/ constant of variation/ rate of change
b = y-intercept
To find the slope, use the formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Find two random points:
1 - (0.5, 40) , 2 - (1, 60)
Plug in:
[tex]\frac{60-40}{1-0.5}[/tex]
Solve:
[tex]\frac{20}{0.5}[/tex]
Divide:
[tex]\frac{1}{40}[/tex]
The y-intercept is when the x-coordinate is equal to 0.
The y-intercept is always the beginning.
So observing the graph, the first point is (0, 20)
The x-coordinate is 0.
Y intercept = 20.
Plug in both slope and y-intercept:
y = 1/40x + 20
