Answer:
V = 564.2 m^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
V = 1/3 pi (7)^2 (11)
V =539 /3 * pi
Letting pi be approximated by 3.14
V = 564.1533333 m^3
Rounding to the nearest tenth
V = 564.2 m^3
Answer:
564.512 m³
Step-by-step explanation:
Formula to find the volume of a cone is :
Volume = [tex]\frac{1}{3}[/tex] π r² h
Here,
r = radius = 7 m
h = height = 11 m
Let us solve now.
Volume = [tex]\frac{1}{3}[/tex] π r² h
Volume = [tex]\frac{1}{3}[/tex] π ×7² × 11
Volume = [tex]\frac{1}{3}[/tex] π × 49 × 11
Volume = [tex]\frac{1}{3}[/tex] π × 539
Volume = [tex]\frac{1}{3}[/tex] × 1693.538
Volume = 564.512 m³

find the speed of a car if it can travel a distance of 217 km in 3 hours 30 minutes
Answer:
65.1 km/hr
Step-by-step explanation:
The car travelled 217km in 3 hours and 20 minutes. We can divide the km by the time to obtain a speed that is km per a time value. If we would like it expressed as km/hour, we will need to convert the 20 minutes into hours.
20 minutes is (20 minutes)*(1 hour/60 minutes) = (1/3) hour
The total time to travel 217km is 3 and 1/3, or (10/3) hours.
The speed is (217 km/((10/3) hours)
Speed = 65.1 km/hr

Two angles are vertical angles. The measure of one angle is 36º. The measure of the other angle
is (4x). What is the value of x?
Answer:
x = 9
Step-by-step explanation:
Vertical angles has same measurement so the two angles are equal:
if one of the angle is 36 and the other is represented by 4x then the value of x:
4x = 36 divide both sides by 4
x = 9

Which one of the following equations is equivalent to the equation ?
A
6x−22=26x-22=2
We simplify the equation :
2(x+3) + 5x = 34
= 2x + 6 + 5x
= 7x + 6
So, 7x + 6 = 34
x = (34-6)/7 = 4
Equation A : 6x - 22 = 2
x = (22+2)/6 = 4 (so it's equvalent).
Equation B : x/5 = 4
x = 4 x 5 = 20 (not equivalent)
Equation C :
3x - 6 = 12
x = (12+6)/3 = 6 (not equivalent)
Equation D : 6x = 18
x = 18/6 = 3 (not equivalent)
So, it's equation A

Todd helps his dad with his landscaping business during the summer. He earns $10 for each shrub he plants and $25 for each lawn he mows. If Todd planted 194 shrubs and mowed 62 lawns, how much money did Todd earn?
Answer:
Todd earned: $3490
Step-by-step explanation:
First you have to times 10 ($ per shrub) by 194 (# of shrubs planted) and 25 ($ per lawn) by 62 (# of lawns mowed)
10 * 194 = 1940
25 * 62 = 1550
Then you have to add the two together to get the total amount of money he earned.
10 * 194 + 25 * 62 = 3490
Can you do question b for me I don’t understand

Will give brainilest if correct Element X decays radioactively with a half life of 15 minutes. If there are 770 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 32 grams?
Answer:
The time it'd take for the element to have 15 g of mass is approximately 68 min.
Step-by-step explanation:
The radioactive decay of a substance is given by the following formula:
Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:
Therefore the mass of the element is given by:
If the initial mass is 760 g and the final mass is 15 g, we have:
The time it'd take for the element to have 15 g of mass is approximately 68 min.Step-by-step explanation:

Answer:
x=4 y=6
Step-by-step explanation:
y=−1/2x+8;3x+4y=36
Step: Solvey=
−1/2x+8for y:y=−1/2x+8
Step: Substitute
−1/2x+8foryin3x+4y=36:
3x+4y=363x+4(−1/2
x+8)=36
x+32=36(Simplify both sides of the equation)
x+32+−32=36+−32(Add -32 to both sides)
x=4
Step: Substitute4forxiny=
−1/2x+8:y=−1/2x+8
y=−1/2(4)+8
y=6(Simplify both sides of the equation)
Answer:
x=4 and y=6
[tex]3x+4y=36\\y=-\frac{1}{2} x+8\\\\[/tex]
Since we know the value of y in the second equation, let us plug it into the first equation
[tex]3x+4(-\frac{1}{2} x+8) = 36\\3x-2x+32 = 36\\x = 4[/tex]
Now let us plug our known value of x into the second equation, [tex]y=-\frac{1}{2} x+8[/tex]
[tex]y=-\frac{1}{2} x+8 =- \frac{1}{2} *4+8 = 6[/tex]
So x = 4 and y = 6

How to find circumcenter of a triangle with vertices.
Answer:
The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. In other words, the point of concurrency of the bisector of the sides of a triangle is called the circumcenter. It is denoted by P(X, Y). The circumcenter is also the centre of the circumcircle of that triangle and it can be either inside or outside the triangle.
Step-by-step explanation:
Steps to find the circumcenter of a triangle with vertices are:
Calculate the midpoint of given coordinates, i.e. midpoints of AB, AC, and BC
Calculate the slope of the particular line
By using the midpoint and the slope, find out the equation of the line (y-y1) = m (x-x1)
Find out the equation of the other line in a similar manner
Solve two bisector equations by finding out the intersection point
Calculated intersection point will be the circumcenter of the given triangle
