Answer:
41.67πunits³
Step-by-step explanation:
Since we are not asked what to find, we can as well look for the volume of the cone.
Find the diagram of the cone attached
Volume of the cone = 1/3πr²h
h is the height of the cone
r is the radius of the cone
Volume of the cone = 1/3π(5)²(5)
Volume of the cone= 1/3π(125)
Volume of the cone = 125π/3
Volume of the cone = 41.67πunits³

Answer:
x = 4
y = 13
Step-by-step explanation:
x + y = 17
y = 2x + 5
substitute for y:
x + (2x + 5) = 17
reduce:
3x + 5 = 17
subtract 5 from each side:
3x = 12
divide both sides by 3:
x = 4
y = 2(4) + 5
y = 13
Write how you would solve this equation. Be thorough in your explanation to show what you know. -5x+3=18 I NEED HELP ASAP
Answer:
x= -3
Step-by-step explanation:
-5x+3=18
-3 on both sides
-5x=15
divide by -5 on both sides
x= -3
Answer:
X= -3
Step-by-step explanation:
-5x+3=18 subtract 3 from both sides this removes the +3 from the left side and makes the 18 into 15
-5x=15 Divide both sides by -5
x=-3
PLEASE GEOMETRY HELP WILL MARK BRAINLIEST!!!
Answer:
120
Step-by-step explanation:
First we can find the value of each exterior angle
The sum of the exterior angles is 360
because a hexagon has 6 congruent exterior angles we divide 360 by 6
360/6=60 so each exterior angle is equal to 60 degrees
the exterior angle and interior angles of any regular polygon are supplementary angles ( meaning the sum of the two is 180) so to calculate the interior angle we subtract 60 from 180
180-60=120 so each measure of the interior angle of a hexagon is 120 degrees
please help this is TIMED!
Answer:
angle 1 = 51 degrees
angle 2 = 18 degrees
angle 3 = 123 degrees
angle 4 = 39 degrees
Step-by-step explanation:
angle 2 = 90-72 = 18
angle 3 = 180 - 57 = 123
angle 4 = 180 - 123 - 18 = 39
angle 1 = 90 - 39 = 51
Jacob is painting a circular picture on his wall. If the painting has a diameter of 6 ft, how much paint will he need to cover the inside of the circle?
Answer:
28.278ft^2
Step-by-step explanation:
Given data
Diameter of painting= 6ft
Radius= 3ft
Let us find the area of the painting
Area= πr^2
Substitute
Area= 3.142*3^2
Area= 3.142*9
Area= 28.278ft^2

Step-by-step explanation:
in the given figure p=120° and y : z=2 : 3 Find x, y and z
Answer:
x = 60°
y = 72°
z = 48°
Step-by-step explanation:
x = 180 - p = 180 - 120 = 60
Since y;z = 3:2 , 2y = 3z or z = 2y/3
Now, x + y + z = 180
60 + y + 2y/3 = 180 Multiply thru by 3 to remove the fraction
180 + 3y + 2y = 540
180 + 5y = 540
5y = 360
y = 72
z = 2(72)/3 = 48
Check: 60 + 72 + 48 = 180

The total cost of a tablet device comprises the cost of material, labour and overheads in the ratio 3:4:1. The cost of material is $315. What is the total cost of the tablet?
Answer:
The total cost of the tablet is $840
Step-by-step explanation:
Here, we want to calculate the total cost
Let the total cost be $x
From the ratio, the total ratio is 3 + 4 + 1 = 8
so,;
3/8 * x = 315
3x = 8 * 315
x = 8/3 * 315
x = 8 * 103
x = 840

Hi!
Let's first expand the cotangent of theta.
You'll probably know that tangent will be "y/x", or [tex]\frac{sin(x)}{cos(x)}[/tex], and cotangent is the reciprocal of this, meaning that it is "x/y" or [tex]\frac{cos(x)}{sin(x)}[/tex].
That means that we are now given this equation.
[tex]cos(x)\frac{cos(x)}{sin(x)}+sin(x)[/tex]
That'll multiply to:
[tex]\frac{cos^2(x)}{sin(x)}+sin(x)[/tex]
We'll want a common denominator to add by multiplying [tex]sin(x)[/tex] to both top and bottom of the second term:
[tex]\frac{cos^2(x)}{sin(x)}+\frac{sin^2(x)}{sin(x)}[/tex]
[tex]\frac{cos^2(x)+sin^2(x)}{sin(x)}[/tex]
Pythagorean Identity states that [tex]sin^2(x)+cos^2(x)=1[/tex], so substitute that in:
[tex]\frac{1}{sin(x)}[/tex]
Which simplifies to:
[tex]csc(x)[/tex]

Jason's family of 4 has budgeted at most $100 to spend at the community fair. Admission tickets cost $10 per person. How much can the family spend per person on food, if each person buys a $2 souvenir keychain?
Answer:
2
Step-by-step explanation:
ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
Answer:
$13
Step-by-step explanation:
First, you must find out how much Jason's family is spending on admission and keychains. To find this out, just multiply the $10 and the $2 separately by 4. Once you find out how much the family is spending on each item, add them up. It should look like this:
$10 x 4 = $40
$2 x 4 = $8
$40 + $8 = $48
Next, just subtract the $48 from the initial $100 to find out how much the family as a whole can spend on food.
$100 - $48 = $52
Finally, just divide the $52 by 4 to represent how much each family member can spend.
$52 / 4 = $13
Each person in Jason's family can spend $13 on food. Hope this helps!

x=
Answer:
x = 3√7
Step-by-step explanation:
The Pythagorean theorem states that in a right triangle, the sum of the legs squared and added together is equal to the hypotenuse (the longest side and the one across the 90° angle)
If the legs are a and b, respectfully, and the hypotenuse is c, the equation would be:
a² + b² = c²
Let's apply this to the problem given.
9² + x² = 12²
Simplify.
81 + x² = 144
Subtract 81 from both sides.
x² = 63
Take the square root.
√(x²) = √63 = √(9 * 7) = √(3² * 7)
x = 3√7
Check the answer.
9² + (3√7)² = 12²
81 + 9 * 7 = 144
81 + 63 = 144
144 = 144
Thus, the answer is correct.
I hope this helps! Feel free to ask any questions! :)
