A farmer is painting his silo. A typical can of paint covers 400 squared meters. How many cans of paint will the farmer need to buy in order to paint the entire exterior of the silo?
Answer:
about 13 cans of paint
Step-by-step explanation:
To find how many cans the farmer needs to buy, you need to know the surface area of both the cone and cylinder.
The way to find the SA of the cone would be area = 3.14 x r^2 + 3.14 x r x sqrt(r^2 + h^2).
SA= 1976.0617791 m^2.
The way to find SA of the cylinder under the cone would be 3.14 x d x (d / 2 + h).
A = 3097.6103564 m^2
Then you have to add 1976.0617791+3097.6103564 which gives you 5,073.8. (5,073 being total surface area of the silo)
Next divide that by 400.
5,073.8/400 = 12.7
He would need to buy about 13 cans of paint to be able to paint the entire silo.

A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. The volume of each small box is 6 cubic feet
and the volume of each large box is 22 cubic feet. A total of 22 boxes of paper were
shipped with a combined volume of 324 cubic feet. Write a system of equations that
could be used to determine the number of small boxes shipped and the number of
large boxes shipped. Define the variables that you use to write the system.
Answer:
10 small boxes and 12 large boxes
Step-by-step explanation:
Let x = number of large boxes
Let y = number of small boxes
We are told that;
volume of each small box = 6 cubic feet
volume of each large box = 22 cubic feet.
Total volume = 324 ft³
Thus;
6x + 22y = 324 - - - (eq 1)
We are told that 22 boxes of paper were shipped.
Thus; x + y = 22 - - - (eq 2)
Making x the subject in eq 2 gives;
x = 22 - y
Put 22 - y for x in eq 1;
6(22 - y) + 22y = 324
132 - 6y + 22y = 324
16y = 324 - 132
16y = 192
y = 192/16
y = 12
So, x = 22 - 12 = 10
The price of a gallon of unleaded gas has dropped to $2.80 today. Yesterday's price was $2.86 . Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Which line is tangent?
18% as a fraction in its simplest form
Answer:
9/50
Step-by-step explanation:
18% = 18/100
GCF of 18 and 100 = 2
(18 ÷ 2)/(100 ÷ 2)
9/(100 ÷ 2)
9/50
I need help who ever get it right get brainly
Answer:
m<a = m<c since those two angles are vertical angles.
m<a + m<b = 90⁰ since, if you look closely m<a and m<b forms a 90⁰ angle that means it is equal to 90⁰.
Hope this helps and I would appreciate if you give me the brainlist or not thank you :) !!

What is the y-intercept of function g if g(x) = 2f(x) + 1 ?
A. (0,2)
B. (0,-1)
C. (0,3)
D. (0,1)
By evaluating the function in x = 0, we will see that the y-intercept is (0, 3), so the correct option is C.
How to find the y-intercept of a function?
The y-intercept of a function g(x) is given by evaluating the function in x = 0.
So the y-intercept of g(x) is:
y = g(0).
In this case, we have:
g(x) = 2f(x) + 1
The y-intercept will be:
g(0) = 2*f(0) + 1
By looking at the graph, we can see that f(0) = 1, replacing that above we get:
g(0) = 2*1 + 1 = 3
Then the y-intercept is the point (0, 3), meaning that the correct option is C.

Answer: 14
Step-by-step explanation: 3 to the second is 3 twice EX. 3x3=9, 9+5=14
Answer: x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
x2+5x−3=3−3
x2+5x−3=0
For this equation: a=1, b=5, c=-3
1x2+5x+−3=0
Step 2: Use quadratic formula with a=1, b=5, c=-3.
x= −b±√b2−4ac /2a
x=
−(5)±√(5)2−4(1)(−3) /2(1)
x= −5±√37 /2
x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37

Heather has divided $5600 between two investments, one paying 9% the other paying 5%. If the return investment is $396, how much does she have in each investment?
Answer:
x = 2700 y=2900
Step-by-step explanation:
x+y = 5600
5/100 x + 9/100 y = 396
x+y=5600
5x+9y=39600
5x+5y = 28000
5x+9y=39600
-4y = -11600
y= 2900
x = 5600-2900 = 2700
LAST QUESTION PLS HELP. (It's not solve for x)
Answer:
40
Step-by-step explanation:
So, if the angle shown, one of them is 70. the other is 110, because line is 180 degress, 180-70 = 110. C is 110. But, we need to find B. 13x + 6 must also be 70 degrees. 70-6 = 64. 64/13 = about 5. A is 100. The inner angles are 70+70+N. Angles in triangle are 180, so N is 180-70-70, which is 180-140. The B is 40 degrees.
Answer:

Answer:
Step-by-step explanation:
Use Pythagorean theorem,
Base² + altitude² = hypotenuse²
15² + altitude² = 17²
225 + altitude² = 289
altitude² = 289 - 225
altitude² = 64
altitude² = 8²
altitude = √8²
altitude = 8
P = 8 + 15 + 17 = 40 units
[tex]A= \frac{1}{2}*base * height\\\\ = \frac{1}{2}* 15 * 8\\\\= 15 * 4\\\\= 60 sq. units[/tex]
