The exterior surface of a farm silo needs to be painted. if one gallon of paint covers 224 square feet, what is the minimum number of gallons needed to paint the silo? keep in mind that the bottom of the silo is not painted. use π = 3.14
The gallons needed to paint the silo is 10.
How many gallons is needed to paint the silo?A cylinder is a three-dimensional object. It is a prism with a circular base. The total surface area of cylinder can be determined by adding the area of all its faces.
Total surface area of the cylinder excluding its base = 2πrh +πr²
Where:
r = radius h = heightTSA = (2 x 3.14 x 10 x 30) + (3.14 x 10²)

Solve:
4(2 + a) = 24
A =
Answer:
a=4Step-by-step explanation:
Simplify both sides of the equation:
4 (2 + a) = 24
( 4 )( 2 ) + ( 4 )( a ) = 24 (Distribute)
8 + 4a = 24
4a + 8 = 24
subtract 8 from both sides:
4a + 8 − 8 = 24 − 8
4a = 16
Divide both sides by 4:
4 a/4 = 16/4
a = 4
Multiple bracket out first:
4 x 2 =8
4 x a = 4a
8 +4a = 24

What is equilibrium constant?A reaction involves the conversion of reactants to products. Now we know that the number that shows us the extent to which we can convert the reactants to products is given by the equilibrium constant. If the equilibrium constant is large and positive, then the reaction tends towards the conversion of reactants to products. on the other hand, when the reaction has a small equilibrium constant, then the reaction tends towards the reactants.
Thus, the magnitude of the equilibrium constant tells us how easily reactants are converted into products and this is necessary when we are trying to predict the direction in which a reaction will go or make calculations.

C represents the circumference.
C = 2πr ,where r is the radius.
We are given C = 62.8 ft
Equating the two expressions of C :
2πr = 62.8
Then
2 × 3.14 × r = 62.8

13. In A ABC, if m
BF is an angle bisector, find

If in the triangle ABC , BF is an angle bisector and ∠ABF=41° then angle m∠BCE=8°.
Given that m∠ABF=41° and BF is an angle bisector.
We are required to find the angle m∠BCE if BF is an angle bisector.
Angle bisector basically divides an angle into two parts.
If BF is an angle bisector then ∠ABF=∠FBC by assuming that the angle is divided into two parts.
In this way ∠ABC=2*∠ABF
∠ABC=2*41
=82°
In ΔECB we got that ∠CEB=90° and ∠ABC=82° and we have to find ∠BCE.
∠BCE+∠CEB+EBC=180 (Sum of all the angles in a triangle is 180°)
∠BCE+90+82=180
∠BCE=180-172
∠BCE=8°

9a=(√3)a+2
9a=1.732051a+2
Solve Exponent.
9a=1.732051a+2
log(9a)=log(1.732051a+2)(Take log of both sides)
a*(log(9))=(a+2)*(log(1.732051))
a=(log(1.732051)/log(9))*(a+2)
a=0.25*(a+2)
a=0.25a+0.5(Simplify both sides of the equation)
a−0.25a=0.25a+0.5−0.25a(Subtract 0.25a from both sides)
0.75a=0.5
0.75a/0.75=0.5/0.75

if an average orange weighs 75 g, how many oranges would weigh 4.5 kg?
Answer: 60 oranges
Step-by-step explanation:
Given information
Weight = 75 g / orange
Total = 4.5 kg
Given formula
Total = Number of oranges × Average weight
Convert Kilogram unit to Gram
1 kg = 1000 g
4.5 kg = 4.5 × 1000 = 4500 g
Substitute values into the given formula
Total = Number of oranges × Average weight
Number of oranges = Total / Average weight
Number of oranges = 4500 / 75
Simplify by division
[tex]\Large\boxed{Number~of~oranges~=~60}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
60 oranges
Step-by-step explanation:
Let the unknown number of oranges be x.Given that,The average weight of an orange ⇒ 75g
Total weight of oranges ⇒ 4.5 kg
Therefore,Number of oranges Weight ( in grams)
1 75 g
x (4.5 × 1000) g
To find the number of oranges we can make an expression like this.1 ⇒ 75
x ⇒ 4500
Use cross multiplication and find the value of x.
75x = 4500 × 1
75x = 4500
Divide both sides by 75.
x = 60
Therefore, 60 oranges would weight 4.5kg16. On your own paper, graph the following system of equations. Describe the graphs (perhaps give a few points on each line) and give the solution to the system of equations.
-2x - 5y = 20
y=4/5x+2
Answer:
(-5, 2)
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}-2x-5y=20\\y=\dfrac{4}{5}x+2\end{cases}[/tex]
Both equations are linear equations.
Equation 1Rearrange Equation 1 to make y the subject:
[tex]\implies -2x-5y=20[/tex]
[tex]\implies -5y=2x+20[/tex]
[tex]\implies y=-\dfrac{2}{5}x-4[/tex]
Therefore, the graph of this equation is a straight line with a negative slope and a y-intercept of (0, -4).
Find two points on the line by substituting two values of x into the equation:
[tex]x = 0\implies y=-\dfrac{2}{5}(0)-4=-4 \implies (0,-4)[/tex]
[tex]x = 5 \implies y=-\dfrac{2}{5}(5)-4=-6 \implies (5,-6)[/tex]
Plot the found points and draw a straight line through them.
Equation 2The graph of this equation is a straight line with a positive slope and a y-intercept of (0, 2).
Find two points on the line by substituting two values of x into the equation:
[tex]x = 0 \implies y=\dfrac{4}{5}(0)+2=2 \implies (0,2)[/tex]
[tex]x = 5 \implies y=\dfrac{4}{5}(5)+2=6 \implies (5,6)[/tex]
Plot the found points and draw a straight line through them.
SolutionThe solution(s) to a system of equations is the point(s) of intersection.
From inspection of the graph, the point of intersection is (-5, -2).
To verify the solution, substitute the second equation into the first and solve for x:
[tex]\implies \dfrac{4}{5}x+2=-\dfrac{2}{5}x-4[/tex]
[tex]\implies \dfrac{6}{5}x=-6[/tex]
[tex]\implies 6x=-30[/tex]
[tex]\implies x=-5[/tex]
Substitute the found value of x into one of the equations and solve for y:
[tex]\implies \dfrac{4}{5}(-5)+2=-2[/tex]
Hence verifying that (-5, -2) is the solution to the given system of equations.

=> ∠BEC = ∠AED { vertically opposite angles }
∠AED = (7x + 15)°

=> ( 5x-3) + ( 7x+15) = 180°

Of all closed rectangular boxes of volume 64 ft3, what is the smallest surface area?
The smallest surface area of cubic rectangular boxes = 96 ft²
What is surface area?An object with three dimensions is solid and has both height and depth. A sphere and a cube, for instance, have three dimensions, whereas a circle and a square do not.
A three-dimensional shape's total surface area equals the sum of its side's surface areas. The measured area of all surfaces of three-dimensional solids, such as cubes, spheres, prisms, and pyramids, is expressed in square units.
Since it is a closed rectangular box so, there will be two equal sides.
According to the given Information:Volume = 64 ft³
Volume of rectangular cube = hx²
Surface area of rectangular cube = 2x²+4hx
Equating the above equation we get, hx² = 64
h=64/x²
Put the value of h in surface area formula,
S = 2x² + 4(64/x²)*x
S = 2x² + 256/x
For the surface area to be minimum,
ds/dx = 0
4x - (256/x²) = 0
4x³ = 256
x³ = 64
x = 4 ft
Therefore, the smallest surface area
= 2(4)² + (256/4)
S = 32 + 64
= 96 ft²
