What is the volume of this sphere to the nearest hundredth?
solve the system through elimination
Answer:
x=3
y=1
Step-by-step explanation:
-2x - 7y = -13
3x + 6y = 15
3(-2x - 7y = -13) = -6x - 21y = -39
2(3x + 6y = 15) = 6x + 12y = 30
-6x - 21y = -39
---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9
6x + 12y = 30
Therefore, you can say that -9y = -9 so y = 1
FInally, plug that back into either one of the original equations:
3x + 6(1) =15
3x = 9
x = 3

Circle A was translated 3 units to the left and 4 units up to create Circle B. Which rule describes the translation that was applied to Circle A to create Circle B?
Answer:
[tex]B = (x - 3, y + 4)[/tex]
Step-by-step explanation:
Given
Represent the coordinates of circle A with (x,y)
Translation
Left = 3 units
Up = 4 units
Required
Determine the coordinates of B
When a point (x,y) is translated by h units left, the new point is: (x - h, y)
When a point (x,y) is translated by b units up, the new point is: (x, y + b)
So, when circle A is completely translated to B, the new points of B is:
[tex]B = (x - h, y + b)[/tex]
In this case:
[tex]h = 3\ and\ b = 4[/tex]
So:
[tex]B = (x - 3, y + 4)[/tex]

FIND THE LENGTH OF AC
Answer:
AC=18
Step-by-step explanation:
To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²
144-64=b²
80=b²
√80=√b²
8.94427191=b
That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.
AC= 18

Answer:
look below
Step-by-step explanation:
thing to note:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite= side across angle you are using
hypotenuse= side across 90 degree angle
adjacent= remaining side
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6

A path 3m wide is built outside and along the boundary of a square field of side 100m. Find the area of the path.
Answer:
1236 sq. m
explanation:
Side of square field = 100m
Area of the square field = side * side
= 100 * 100
= 10,000 sq. m
A path of 3m wide is built outside and along the boundary.
Side of path = 100(from the side of field) + 3(from the upper side) + 3(from below)
= 100 + 6
= 106 metres.
Area of the along with whole square path with side 106m = side * side
= 106 * 106
= 11,236sq.m
Now, Area of whole square = Areas of square field + area of path
therefore, Area of the path only = 11,236 - 10,000
= 1,236sq.m

A total of 228 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
152
Step-by-step explanation:
Let x be the number of children tickets sold
2x+x=228
combine like terms
3x=228
x=76
adult tickets is two times the amount of x
2x=152

HELP PLEASE!!
Answer:
x = 16
Step-by-step explanation:
hypotenuse= a /sin(α)
= 22.62742
= 16√2
So using this to calculate x:
x = √c2 - a2
= √22.627416997972 - 162
= √256
= 16

Find the volume of a cube with a side length of 14.4 m, to the nearest tenth of a cubic meter (if necessary).
Answer: 2,986 m³
Step-by-step explanation: to find the volume, you multiply the length, width , and height. since we're told this is a cube, we know that all sides are congruent, so you do 14.4 x 14.4 x 14.4 which equals about 2985.98. when rounding the solution to the nearest tenths, the answer becomes 2986 m³
If the edge length of the cube is 14.4 meters. Then the volume of the cube will be 2986 m³
What is a volume of a cube?Suppose that: The side length of the considered cube is L units. Then, we get:
Volume of that cube = L³ cubic units.
The edge length of the cube is 14.4 meters. Then the volume of the cube will be
Volume = 14.4³
Volume = 2985.98
Volume ≅ 2986 m³
More about the volume of the cube link is given below.
