Answer:
the company must buy 22 gallons to paint this entire area
Step-by-step explanation:
The circumference of the tank is given and is C = 2(pi)r, where r is the area.
118 ft
Here the circumference is C = 2(pi)(r) = 118 ft, which leads to r = ------------ ≈
18.79 ft ≈ r 2(pi)
The area of the sides is A = (circumference)(height), or approximately
(118 ft)(50 ft) = 5900 ft², and the area of the top is A = πr², which here comes to (π)(18.79 ft)² ≈ 1109 ft². Combining these two sub-areas, we get:
A(total) = 1109 ft² + 5900 ft² ≈ 7009 ft²
To determine how many gallons of paint will be needed to paint only the top and sides, we divide 7009 ft² by the coverage rate, which is
320 ft²
-----------
1 gallon
which results in:
7009 ft²
---------------------- ≈ 21.9 gallons
320 ft² / gallon
Since the paint comes only in full gallon cans, the company must buy 22 gallons to paint this entire area.
i dont know if im right or not but i think its G can anyone help?
Which is NOT an example of the commutative property of addition?
x + (-13) = -13 + x
2 + x + 5 = 2 + 5 + x
x - 13 = 13 - x
-x + 5 = 5 + (-x)
Answer:
x - 13 = 13 - x
Step-by-step explanation:
The commutative property of addition is a+b=b+a
The third equation is the only one not following the rule. It states that a-b=b-a, whoich is not true.
For exaple, 2-1 is not equal to 1-2.

What is the area of this shape? ANSWER AS FAST AS YOU CAN!!!!
Answer: 5x4x8x4x5x2x6x8x1
Step-by-step explanation:
Answer:
32 Square centimeters
Step-by-step explanation:
You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.
Hope my answer helped!
On Sunday, Sheldon bought 4 1 2 kg of plant food. He used 1 2 3 kg on his strawberry plants and used 1 4 kg for his tomato plants. How many kilograms of plant food did Sheldon have left? Write one or more equations to show how you reached your answer.
Answer: 2 1/2kg
Step-by-step explanation:
Weight of plant food bought = 4 1/2kg
Amount used on strawberry plant = 1 2/3kg
Amount used on tomato plant = 1/4kg
Therefore, the amount used will be:
= 1 2/3 + 1/4
= 1 8/12 + 3/12
= 1 11/12kg
We then subtract the value gotten from the amount bought. This will be:
= 4 1/2 - 1 11/12
= 4 6/12 - 1 11/12
= 2 6/12
= 2 1/2kg
which expression is equivalent to (3x+4)(7x-2)
Answer:
21x² + 22x - 8
Step-by-step explanation:
(3x+4)(7x-2) = 21x² - 6x + 28x - 8 = 21x² + 22x - 8
Answer:
B.
Step-by-step explanation:
Let's use the FOIL (First, Outside, Inner, Last) method.
We need to multiply the first terms in each pair of parentheses, which are
3x and 7x.
Multiplying, we get [tex]21x^2[/tex].
We multiply the outside terms in each pair, which are 3x and -2.
Multiplying, we get [tex]-6x[/tex]. Remember that since -2 is negative, then the whole product is negative.
We need to multiply the inner terms now. They are 4 and 7x.
Multiplying, we get [tex]28x[/tex].
Finally, we multiply the last terms in each pair of parentheses. they are 4 and -2.
Multiplying, we get [tex]-8[/tex].
Now, we put the terms together.
[tex]21x^2-6x+28x-8[/tex]
We can combine -6x, and 28x. Doing this, we get
[tex]21x^2+22x-8[/tex]. Which gives us B.
I hope this helped.

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Simple maths.
Here,
61 = r/3 - 7
hence, r/3 = 61+7
===> r/3 = 68
==> r = 68*3
====> r = 204
Option c.) is correct.
Please help me with my algebra homework (Attachment)
Answer:
D.
Step-by-step explanation:
To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.
What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5
B.
left = -5 - 5 = -10
right = -(2/3)(4 + 4) = -16/3
So it's D. Let's verify:
D.
left = -5 + 5 = 0
right = -(2/3)(4 - 4) = 0
Checks out.
Answer:
Option D
Step-by-step explanation:
→ Find the gradient of the parallel line
[tex]y=-\frac{2}{3} x+c[/tex]
→ Substitute in the coordinates as x and y values to find c
[tex]5=-\frac{2}{3} *-4+c[/tex]
→ Simplify
[tex]5=\frac{8}{3} +c[/tex]
→ Minus [tex]\frac{8}{3}[/tex] from both sides to find c
[tex]c = \frac{7}{3}[/tex]
→ Expand out all options and then see which one contains all the numbers above
Option D

A. (-3,3)
B. (0,3)
C. (3,-1)
D. (1,0)
Answer:
Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.

Write an equation of The line that passes through the given point and is parallel to the given line (4;5);y=-3/2x+3
9514 1404 393
Answer:
y = -3/2x +11
Step-by-step explanation:
The slope of the parallel line is the same as the slope of the given line, so ...
m = -3/2
The y-intercept of the parallel line can be found from ...
b = y -mx
b = 5 -(-3/2)(4) = 11
So, the desired equation is ...
y = mx +b
y = -3/2x + 11
_____
Additional comment
Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.
