the curved sulace of the pillar at the rate of 12,50 per m.
Curved surface area of a right circular cylinder is 44 m. If the radius of the base of the
cylinder is 0.7 m, find its height,
Answer:
The height of cylinder is 10 meters.
Step-by-step explanation:
Given
Curved Surface Area = 44m^2
Radius = r = 0.7 m
The curved surface area of a cylinder is given by:
[tex]CSA = 2\pi rh[/tex]
Putting the values we get
Pi can be taken as 22/7 or 3.14
We are taking 22/7 for the question
[tex]44 = 2 * \frac{22}{7} * 0.7 *h\\44 * \frac{7}{22} = 1.4h\\14 = 1.4h\\h=\frac{14}{1.4}\\h=10 m[/tex]
Hence,
The height of cylinder is 10 meters.

m is proportional to the cube of r. when r=3m,m=216.when r=5 find the value of m
Answer:
The value of m is 1000 for r=5
Step-by-step explanation:
Given that m is proportional to the cube of r
It can be written as:
[tex]m \propto\ r^3[/tex]
When the proportionality symbol is removed a proportionality constant is introduced in the equation.
Let k be the proportionality constant
[tex]m = kr^3[/tex]
Given
r=3,m=216
Putting the values
[tex]216 = k(3)^3\\216 = k * 27\\k = \frac{216}{27}\\k = 8[/tex]
The equation will now become
[tex]m = 8r^3[/tex]
Putting r = 5
[tex]m = 8(5)^3\\m = 8 * 125\\m = 1000[/tex]
Hence,
The value of m is 1000 for r=5

A trapezoid has a set of parallel bases with lengths 3 inches and 5 inches and a helght of 8 inches. What is the area
the trapezoid?
Answer:
The area of trapezoid is 32 inches^2
Step-by-step explanation:
Parallel base 1 = a = 3 inches
Parallel base 2 = b = 5 inches
Height of trapezoid = 8 inches
We need to find area of trapezoid
The formula used is: [tex]Area\:of\:trapezoid=\frac{a+b}{2}\times h[/tex]
Now putting the values and finding area of trapezoid
[tex]Area\:of\:trapezoid=\frac{a+b}{2}\times h\\Area\:of\:trapezoid=\frac{5+3}{2}\times 8\\Area\:of\:trapezoid=\frac{8}{2}\times 8\\Area\:of\:trapezoid=4\times 8\\Area\:of\:trapezoid=32[/tex]

James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package. If he received $33 dollars of his refund, how many packages of batteries did he buy?
Answer:
4
Step-by-step explanation:
he should have gotten 45 back
but he only got 33
so the DIFFERENCE is how much he got in batteries, how many packs? well 45−33 = 12 12÷3=4
James bought 4 packages of batteries if James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package
Let he buy x number of packages of batteries.
The cost of packages of batteries = 3x
The linear equation one variable can be framed:
33 + 3x = 45
3x = 45 - 33
3x = 12
x = 4
Thus, James bought 4 packages of batteries if James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package.

Answer:
Area of figure is 51 cm²
Step-by-step explanation:
We need to find the area of the figure given.
The figure is basically a combination of 3 rectangles.
Adding area of all the rectangles will give the area of the figure.
The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]
Area of rectangle 1:
Length = 7 cm
Width = 3 cm
The area will be:
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2[/tex]
The area of rectangle 1 is 21 cm²
Area of rectangle 2
Length will be: 7-4 = 3cm
Width will be: 3 cm
The area will be:
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=3\times 3\\Area\:of\:rectangle=9 \:cm^2[/tex]
The area of rectangle 2 is 9 cm²
Area of rectangle 3
Length will be: 7cm
Width will be: 3 cm
The area will be:
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2[/tex]
The area of rectangle 3 is 21 cm²
The total area of the figure will be:
Area of figure = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Area of figure = 21+9+21
Area of figure = 51 cm²
So, Area of figure is 51 cm²

y=6x−7. Identify the x-intercept.
Answer: x = 7/6
Step-by-step explanation:
X intercept is when y = 0.
Set y = 0
0 = 6x - 7
Add 7 to both sides
7 = 6x
Divide by 6
x = 7/6
Answer:
x = 7/6
Step-by-step explanation:
When finding the x-intercept using slope intercept form. Substitute 0 for y and solve for x.
0 = 6x - 7
~Add 7 to both sides
7 = 6x
~Divide 6 to both sides
7/6 = x

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.
9x^2-36x+16
A.True
B.False
Step-by-step explanation:
9x² - 36x + 16
= (Ax - B)² = A²x² - 2ABx + B².
By Comparing Coefficients, we have:
A² = 9,
2AB = 36,
B² = 16.
It is obvious that A = 3 and B = 4.
However 2AB = 2(3)(4) = 24 which is not equal to 36.
Hence 9x² - 36x + 16 is not a perfect square trinomial.
Answer:
False
Step-by-step explanation:
The polynomial cannot be factored.
