Find the total surface area of this cone.
Leave your answer in terms of .
15 cm
8cm
SA = [ ? ]cm2
Hint: Surface Area of a Cone = tre + B
Where e = slant height, and B = area of the base
Answer:
200π cm^2
Step-by-step explanation:
Sb = 8^2 π = 64π cm^2
a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm
Sl = 8x17xπ = 136 π cm^2
SA = 136π + 64π =200π cm^2

Answer:
A = 27.2 mm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 8 and h = 6.8 , then
A = 0.5 × 8 × 6.8 = 4 × 6.8 = 27.2 mm²
Perform the indicated operation and simplify. (x+3)(x2−5x+2) Write your answer in standard form. No spaces when entering your answers. For this question, you will have to use the carrot key ^ for an exponent and the carrot key is found by pressing "shift" and "6". For example, 42 would be entered as 4^2
Answer:
x^3-2x^2-13x+6
Step-by-step explanation:
We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;
(x+3)(x^2−5x+2)
Expand
= x(x^2)-5x(x)+2x+3x^2-3(5x)+6
= x^3 - 5x^2+2x+3x^2-15x+6
Collect the like terms
= x^3 - 5x^2+3x^2+2x-15x=6
= x^3-2x^2-13x+6
This gives the required expression

Can somebody help me with this math equation?
Answer:
10/3 or reduced to 1 1/3
Step-by-step explanation:
So mutiplying equations are pretty simple. But we can notice that we have a number instead of a fraction. When we see this, a thing that automatically goes through my head is, that a number as a fraction is also 5/1. From there you equation is now 2/3x5/1. We can now multiply the top two numbers and the bottom two numbers. Which equals 10/3.
☁️ Answer ☁️
10/3
Here's the mixed number form:
3 1/3.

how do you write a linear equation that relates y to x
Answer:
Find the slope and y-intercept of the line. = −2 Because the line crosses the y-axis at (0, 3), the y-intercept is 3. So, the linear function is y = −2x + 3. Use the graph or table to write a linear function that relates y to x.

Answer:
Area = 117 sq. ft.Perimeter = 44 feetStep-by-step explanation:
Given,
Length of the bedroom = 13 feet
Width of the bedroom = 9 feet
Therefore,
First Case:
Area of the bedroom = Length × Width
= 13 feet × 9 feet
= 117 sq. ft.
Second Case:
Perimeter of the bedroom = 2(Length + Width)
= 2 (13 + 9) feet
= 2 × 22 feet
= 44 feet
Hence,
Required area of the bedroom is 117 sq. ft. and perimeter of the bedroom os 44 feet (Ans)
Workout plus offers a membership for $30 each month plus a $100 startup fee. Fit Works offers a membership for $50 each month plus a $20 startup fee. After how many months will memberships to both gyms cost the same amount?
Answer:
4 months
Step-by-step explanation:
Let
x = number of months
Workout plus = 100 + 30x
Fit works = 20 + 50x
After how many months will memberships to both gyms cost the same amount?
Equate the cost of both gyms
Workout plus = Fit works
100 + 30x = 20 + 50x
100 - 20 = 50x - 30x
80 = 20x
x = 80/20
x = 4 months
After 4 months, memberships to both gyms cost the same amount

Although you love to watch TV, you have made a goal to spend more time outdoors. You decide that you will spend 222 times as many hours outdoors as you spend watching TV. Write an equation for the number of hours you will spend outdoors, ooo, when you spend ttt hours watching TV.
Answer:
the equation that should be required is 0 = 2t
Step-by-step explanation:
Let us assume the hours of television be t
And, for hours outdoor be o
As the hours outdoors would be twice the hours of television so the equation is
0 = 2t
Therefore the equation that should be required is 0 = 2t
The same is relevant
Answer:
o = 2t
Step-by-step explanation:
You will spend 2 times as many hours outdoors as you spend watching TV. The number of hours you spend outdoors depends on t, the number of hours you spend watching TV.
To find the number of hours you will spend outdoors, o, you can use the equation o = 2t
Remember, you want to find the number of hours you will spend outdoors if you spend 4 hours watching TV and 8 hours watching TV.
8 = 2 x 4
16 = 2 x 8
Now we can turn the values from the equation into ordered pairs in the form (x , y).
The ordered pairs are (4 , 8) and (8 , 16).
Solve for x. round to the nearest tenth. please help!!

Write an equation of the line that passes through the points ( 2,6) and (- 8, 1)
Answer:
[tex]y = \frac{1}{2} x+5[/tex]
Step-by-step explanation:
1) First, find the slope of the line that passes between the two points. Substitute the x and y values of (2,6) and (-8,1) into slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Then, solve:
[tex]m = \frac{(1)-(6)}{(-8)-(2)} \\m = \frac{1-6}{-8-2} \\m = \frac{-5}{-10} \\m = \frac{1}{2}[/tex]
So, the slope is [tex]\frac{1}{2}[/tex].
2) Now, write the equation of the line using the point-slope formula, [tex]y-y_1 = m (x-x_1)[/tex]. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{1}{2}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of one of the given points into the formula as well. (Any of the two will do. Either choice will represent the same line. I chose (2,6).) Then, isolate y to put the equation in slope-intercept form and find an answer:
[tex]y-6 = \frac{1}{2} (x-2)\\y-6 = \frac{1}{2} x-1\\y = \frac{1}{2} x+5[/tex]
