is the solution of 1/3x=21? greater than or less than 21?
the volume F of the cylinder is 65n cubic centimeters. the height of the cylinder is 5 centimeters. use the vomula v=Bh to find the area of the base of the cylinder?
the total area of triangle is 44 sq in. the area of the triangle is 20 sq in. write and solve an equation to find the area of the recatngle
1/3x=21
x = 21/(1/3)
x = 21 * (3/1)
x = ?
v = Bh
65 = 5B
? = B
The third problem doesn't make sense.
if 1/3 of x = 21, then x surely is greater than 21
F = Bh
65n = B*5
B = 13n
no idea how the rectangle and triangle are related. If the triangle is completely inside the rectangle, then just subtract its area from the rectangle's.
To solve the equation 1/3x = 21, you need to isolate x.
Step 1: Multiply both sides of the equation by 3 to eliminate the fraction:
1/3x * 3 = 21 * 3
x = 63
Therefore, the solution to the equation 1/3x = 21 is x = 63.
Next, to find the area of the base of the cylinder using the formula V = Bh:
Given information:
Volume (V) = 65n cubic centimeters
Height (h) = 5 centimeters
Step 1: Substitute the given values into the formula:
65n = B * 5
Divide both sides of the equation by 5 to isolate B:
65n / 5 = B
B = 13n
Therefore, the area of the base of the cylinder is 13n square centimeters.
Finally, to find the area of the rectangle, given that the total area of the triangle is 44 sq in and the area of the triangle is 20 sq in:
Let A be the area of the rectangle.
Step 1: Use the information given to set up the equation:
Total area = area of triangle + area of rectangle
44 = 20 + A
Step 2: Subtract 20 from both sides of the equation:
44 - 20 = A
A = 24
Therefore, the area of the rectangle is 24 square inches.
To solve the equation 1/3x = 21, you can use algebraic steps to isolate the variable x.
1. Multiply both sides of the equation by 3 to eliminate the fraction: 3 * (1/3x) = 3 * 21.
This simplifies to: x = 63.
Since the value of x is 63, which is greater than 21, the solution to the equation 1/3x = 21 is greater than 21.
To find the area of the base of a cylinder, you need to use the formula for the volume of a cylinder, which is V = Bh. In this case, you are given the volume F as 65 cubic centimeters and the height h as 5 centimeters.
1. Substitute the given values into the formula: 65 = B * 5.
2. Divide both sides of the equation by 5 to isolate B: B = 65/5.
This simplifies to: B = 13.
Therefore, the area of the base of the cylinder is 13 square centimeters.
For a triangle, if you are given the total area and one of the sub-areas (in this case, 20 sq in), you can find the area of the rectangle by subtracting the triangle's area from the total area.
1. Write the equation: Total area = Triangle area + Rectangle area.
2. Substitute the given values: 44 = 20 + Rectangle area.
3. Rearrange the equation to isolate the Rectangle area: Rectangle area = 44 - 20.
This simplifies to: Rectangle area = 24.
The area of the rectangle is 24 square inches.
