Answer:
3631.681108 ft^2
Step-by-step explanation:
The surface area of a cylinder is
SA = 2pi r^2 + 2pi r h where r is the radius and h is the height
= 2pi (17)^2 + 2 pi (17)(17)
= 578pi +578pi
= 1156pi

A construction crew can dig a pit at a rate of
19/14 meters per hour.
How deep can they dig in 6 hours?
A. 57/7 meters
B. 42/7meters
C. 36/7 meters
D. 19/7meters
HELPPP
The distance he can dig is 57/7 m deep
Speed and distanceThe formula for calculating the speed or rate of digging is given as;
Speed = distance/Time
Given the following
Speed = 19/14 meters per hour.
Time = 6hours
Substitute
Distance = 19/14 * 6
Distance = 114/14
Distance = 57/7 meters
Hence the distance he can dig is 57/7 m deep

Answer:
To graph this line, move one of the points to positive three on the horizontal (side to side) line and negative six on the vertical (up and down) line. To get a slope of negative 1/2 you move down one point and right two points, and you continue until you reach the edge of the graph. Then you do the opposite on the way up (up one and left two).
Hope this helps!
Answer: Plot the two points (3,-6) and (1, -5). Draw a straight line through those points.
See the graph below.
=============================================
Explanation:
Plot the point (3, -6)
The slope -1/2 means the rise is -1 and the run is 2
rise = -1run = 2If we moved to the right, then we'd drop down 1 and move to the right 2. That would move us from (3,-6) to (5,-7)
We can go in reverse of this. So instead of "move down 1", we move up 1. We're going left instead of right.
-----------
So we start at (3,-6) and move up 1 and to the left 2 to arrive at (1,-5)
Two points on this line are (1, -5) and (3, -6)
Once we have two points, we have enough to graph the line.
See the graph below.

Answer:
15
Step-by-step explanation:
Answer:
Step-by-step explanation:
For question a: odd + even will always equal odd. so we can use 15 + 40.
For question b: 15 itself is a multiple of b.
For question c: 15 is a factor of 60. There are other answers in there.
For question d: 4^3 = 64, so 64 is one of them.
For the functions f(x) = 2x − 6 and g(x) = 5x + 1, which composition produces the greatest output?
Answer:
g(x) = 5x + 1
Step-by-step explanation:
Given data
We have the following expressions to work with
f(x) = 2x − 6 and
g(x) = 5x + 1
say the value of x = 3
let us put x into the two expressions above and compare the output
f(x) = 2*3 − 6= 6-6= 0
g(x) = 5*3 + 1= 15+1= 16
Hence the second function has the greatest output
Find the value of x that makes m||n
.
135°
m
(2x + 15)
n
Answer:
x = 60
Step-by-step explanation:
Since m is parallel to n, that means they are equal to each other.
In other words:
135 = 2x + 15
Solve for the variable:
120 = 2x
60 = x
Check your work:
135 = 2(60) + 15
135 = 120 + 15
135 = 135
Correct!
Answer:
x = 60
Step-by-step explanation:
For these two lines to be parallel, the angles m and n must be equal. Thus, 135 = 2x + 15.
Excellent. Let’s solve this equation. Subtract 15 from each side. 120 = 2x. Divide by 2, and we get 60 = x, so x = 60.
Hope this helps!

Imagine that your best friend missed the lesson on how to solve a system of equations using the substitution method. You want to help him or her catch up in their math class, so you decide to write an e-mail describing what they missed. Write an email to your friend including:
An explanation of what a system of equations is
A general description of how to use the substitution method
An example of a system of equations
Your solution steps and explanations including the substitution method
Your final answer for the system
Answer:
system of equations: set of one or more equations involving a number of variables
substitution method:
1. Solve one equation for one of the variables.
2. Substitute (plug-in) this expression into the other equation and solve.
3. Resubstitute the value into the original equation to find the corresponding variable.
ex:
-4x+3y=-2 y=x-1
plug in: -4x+3(x-1)=-2
simplify: -x-3=-2
-x=-2+3

Find the lettered angles in each of the following.
( where a point o is given , it is the centre of the circle) .
Answer:
q = 80 degrees
r = 70 degrees
s = 10 degrees
t = 70 degrees
u = 40 degrees
v = 60 degrees
Step-by-step explanation:
starting with the fact that all angles in any triangle always sum up to 180 degrees :
q = 180 - 60 - 40 = 80 degrees
r = 180 - (60+10) - 40 = 180 - 70 - 40 = 70 degrees
the triangle 40-60-q and v-u-blank are similar triangles. your can say the smaller triangle is just a projection of the large triangle through the focal point at angle q.
that means the angles must be equal.
v = 60 degrees
u = 40 degrees
similar for 10-r-blank and t-s-blank.
s = 10 degrees
t = 70 degrees
u=60°
v=40°
q=80°
r=70°
s=70°
t=10°
Answer:
Solution given:
t=10°[inscribed angle on a same chord or arc is equal]
V=40°[inscribed angle on a same chord or arc is equal]
u=60°[inscribed angle on a same chord or arc is equal]
AGAIN;
40+60+10+r=180°[sum of interior angle of triangle]
r+110°=180°
r=180°-110°
r=70°
again
r=s=70°[inscribed angle on a same chord or arc is equal]
again
q=r+10°[exterior angle is equal to the sum of two opposite interior angle]
q=70+10=80°

Equation: (x - 3)^2 + (y + 4)^2 = 36
General Equation of a Circle: (x - h)^2 + (y - k)^2 = r^2
Susan did not account for the fact that the minus sign in front of the x actually indicates a positive x-coordinate. The plus sign in front of the y actually indicates a negative y-coordinate, as well. Therefore, the actual center is (3,-4).
Susan did not take the square root of 36, instead dividing it by 2. The square root of 36 is 6, which means the radius of the circle is 6.

Given the algebraic representation of a linear transformation (x,y) (3x-4, 1/5y-2),what trasformations are occuring
Answer:
We can define the algebraic transformations used here as:
Horizontal translation.
For a general point (x, y), a horizontal translation of N units is written as:
(x + N, y)
if N < 0, the translation is to the left
if N > 0, the translation is to the right.
Vertical translation:
For a general point (x, y), a vertical translation of N units is written as:
(x , y + N)
If N < 0, the translation is downwards
if N > 0, the translation is upwards.
Vertical dilation:
For a point (x, y), a vertical dilation of scale factor k is given by:
(y, k*y)
Horizontal dilation:
A dilation of scale factor k is written as:
(x/k, y)
Here we go from:
(x, y) to (3x - 4, (1/5)*y - 2)
So we have:
An horizontal dilation of scale factor 1/3 followed of a horizontal translation of 4 units.
And a vertical dilation of scale factor (1/5) followed by a translation downwards of 2 units.

Angles of triangle are in the ratio of 23:5. What is the Size of the smallest angle?
Answer:
ratio 2 : 3 : 5
size of smallest angle
[tex]180 \times \frac{2}{10} \\ = 36[/tex]
Answer:
The smallest angle of a triangle is 36°.
Step-by-step explanation:
Given, the ratio of angles of a triangle is 2 : 3 : 5
Let the angles of a triangle be ∠A, ∠B and ∠C.
∠A = 2x, ∠B = 3x, ∠C = 5x
∠A+∠B + ∠C= 180°
[sum of all the angles of a triangle is 180°]
2x + 3x + 5x = 180°
10x = 180°
x=180°/10 =18°
∠A=2x=2 x 18° = 36°
∠B = 3x = 3 x 18° = 54°
∠C = 5x = 5 x 18° = 90°
Hence, the smallest angle of a triangle is 36°.

Hey there!
From the given figure;
Measure of angle V + measure of angle W = measure of angle VUF {exterior angle is equal to the sum of opposite interior angles}
Therefore, angle VUF= 94°.
Hope it helps!
Answer:
<V + <W = < VUF
94 = < VUF
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
<V + <W = < VUF
71+ 23 = < VUF
94 = < VUF
