The figure is made up of 2 cones and a cylinder. The cones and
cylinder have a 4 cm diameter.
What is the exact volume of this figure?
отпCm3
0 12cm
0 207cm
0 367cm
Answers
Answer:
This question is unsolvable because:
1) Volume can't be measured in cm (think you mean cm^3)
2) Volume of the cylinder is calculated with its height and bottom area.
We can calculate its bottom area like this: (4/2)^2*pi
But since we do not know the cylinder nor the cones' height then we can't
calculate their volume.

3m=5(m+3)-3 How do I solve it
Answers
Simplifying
3m = 5(m + 3) + -3
Reorder the terms:
3m = 5(3 + m) + -3
3m = (3 * 5 + m * 5) + -3
3m = (15 + 5m) + -3
Reorder the terms:
3m = 15 + -3 + 5m
Combine like terms: 15 + -3 = 12
3m = 12 + 5m
Solving
3m = 12 + 5m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-5m' to each side of the equation.
3m + -5m = 12 + 5m + -5m
Combine like terms: 3m + -5m = -2m
-2m = 12 + 5m + -5m
Combine like terms: 5m + -5m = 0
-2m = 12 + 0
-2m = 12
Divide each side by '-2'.
m = -6
Simplifying
m = -6
3m=5(m+3)-3 can be solved to get m=-6
An equation is a mathematical statement that shows that two mathematical expressions are equal. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
3m=5(m+3)-3, This can be solved by following the steps mentioned below:
On solving parenthesis
3m=5m+15-3
3m=5m+12
Transposing like terms together,
3m-5m=12
-2m=12
Dividing both sides by -2
-2m/-2=12/-2
m=-6
So, m=-6 for given equation 3m=5(m+3)-3

m(∠KJL) = 54°
Step-by-step explanation:
It's given that two sides of ΔJKL are equal in measure.
Therefore, angles opposite to the equal sides will be equal.
By triangle sum theorem in ΔJKL,
m∠KJL + m∠KLJ + m∠JKL = 180°
2(m∠KJL) + 72° = 180°
2(m∠KJL) = 180° - 72°

Since he ran 2/3 of a mile in 8 minutes, by dividing both sides by two we can see that he ran 1/3 in 4 minutes. 1/3 x 3 = 1 mile. 4 x 3 = 12 minutes
Answer:

1/3 mile = 4 minutes
multiply by 3
1 mile in 12 minutes

Answers
Answer:
6 and 15
Step-by-step explanation:
x^2 + 9x = x^2 + 7x +12
2x = 12
x = 6
The dimension of the original rectangles are 6 inche and 15 inches.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Original rectangle:
Length = x + 9
Width = x
Area = (x + 9)x
New rectangle:
Length = (x + 9) - 5 = x + 4
Width = x + 3
Area = (x + 4)(x + 3)
Now,
(x + 9)x = (x + 4)(x + 3)
x² + 9x = x² + 3x + 4x + 12
9x = 7x + 12
9x - 7x = 12
2x = 12
x = 6
Now,
The dimension of the original rectangle.
x + 9 = 6 + 9 = 15
x = 6
Thus,
The dimensions of the rectangles are 6 inches and 15. inches

The graph of y=f(x) is the solid black graph below. Which function represents the dotted graph?
Not that hard, will give brainlist if correct
Answers
Answer: y = f(x - 4) - 1, lower left corner
=============================================================
Explanation:
Let's focus on only the left-most points of each curve
For the black semicircle, the left-most point is located at (-7,0). The corresponding point on the red semicircle is at (-3,-1)
To go from (-7,0) to (-3,-1), we will do two things
Shift 4 units to the rightShift 1 unit downThis can be done in any order. The action of "shift 4 units to the right" is effectively the same as shifting the xy axis 4 units to the left while keeping the curves fixed in place. This gives the illusion of movement. When we shift 4 the xy axis 4 units to the left, we're replacing each x input with x-4 as the new input.
In short, we go from f(x) to f(x-4). This is why we have this opposite motion going on.
The up and down motion is fairly straight forward. To shift 1 unit down, we subtract off 1. This is to subtract 1 from the y coordinate.
Overall, we go from y = f(x) to y = f(x - 4) - 1
Applying this transformation will move (-7,0) to (-3,-1) as described above. It will also move every other point on the black curve to their new corresponding location on the red curve.
