The height of a cone is 10ft. The area of the base is 22ft. Compute the volume of the cone
[tex] {73.33ft}^{3} [/tex]
Step-by-step explanation:
[tex]v = \pi {r}^{2} \frac{h}{3} [/tex]
[tex]\pi {r}^{2} = {22ft}^{2} [/tex]
[tex]v = 22 \times \frac{10}{3} [/tex]
[tex]v = 22 \times 3.33[/tex]
[tex]v = {73.33ft}^{3} [/tex]
Jasmine correctly determined the area of this parallelogram by adding the areas of the triangles and rectangle.
How did jasmine determine the area?
Enter your answer by filling in the boxes
Jasmine determined that the area of each triangle is _m2 and that the area of the rectangle is _m2. She added the areas of the two triangles and the rectangle for a total area of _
We see that each triangle takes up precisely one half of the parallelogram. From this, we see that the area of a triangle is one half the area of a parallelogram, or the area of a parallelogram is two times the area of a triangle

What are the factors of x2 – x – 6? Check all that apply. X – 6 x 6 x – 3 x – 2 x 2 x 1 x – 1.
Answer:
The factors are x-3 and x+2, and the roots are 3 and -2.
Step-by-step explanation:
x^2-x-6 can be factored in the following way:
(x-3)(x+2)
The factors are x-3 and x+2, and the roots are 3 and -2.
Factored form of an expression is writing it in the terms of multiplication of factors. The factors of given expression are: (x-3) and (x+2)
How to factorize a quadratic polynomial with single variable?Quadratic polynomial with single variables are expressible in the form
[tex]ax^2 + bx + c[/tex]
where x is the variable and a,b,c are constants.
Its factored form is
[tex]\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})[/tex]
For the given case, the expression given to us is [tex]x^2 - x - 6[/tex]
Comparing it with the standard form of quadratic expression [tex]ax^2 + bx + c[/tex], we get: a = 1. b = -1. and c = -6
Using the aforesaid formula, we get:
[tex]=\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})\\\\=\dfrac{1}{4}\times(2x -1 - \sqrt{1 +24})(2a -1 + \sqrt{1 + 24})\\\\=\dfrac{1}{4} \times (2x - 1-5)(2x - 1 + 5)\\\\=(x -3)(x+2)[/tex]
Thus, The factors of given expression are: (x-3) and (x+2)

Grace got a haircut for $26.95, bought three shirts on sale for $18.50 each and a pair of jeans for $48, and purchased two CDs for $18.50 each. Round each amount to the nearest ten dollars to find a reasonable estimate of how much Grace spent.
26.95 + 18.5 * 3 + 48 + 18.5 * 2
18.5 * 3 = 55.5
18.5 * 2 = 37
37 + 55.5 + 48 + 26.95 = 167.45
= $167.5

What is a cuboid?A cuboid is a three-dimensional closed figure which has volume along with surface area.
The volume of a cuboid is the product of its length, width, and height.
The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.
Given, A box that has a volume of 729 inches.
First we'll prime factorize 729.
729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.
If we take the cube root of 729 it would be 3×3 = 9.
So, It is a cube with a side length 9.
Now, We know area of a cube is side².
Therefore, The area of this cube is 9² = 81 in².

How many solutions exist for the given equation?3x + 13 = 3(x + 6) + 1
Answer:
0
Step-by-step explanation:
3x+13=3(x+6)+1
Expand:
3x+13=3x+18+1
Simplify:
3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:
3x=3x+6
Subtract 3x from both sides:
3x-3x=3x-3x+6
0=6
Since the sides are not equal there are no solutions to this problem

Answer:
A relation is a function if for each value of x (input value) there is a unique value of y (output value). For the equation given in the problem:
y= |x| +4
There is a unique value of y for each value of x.
Therefore, the equation is a function and a function is also a relation.

The ratio of centimeters on a map to distance in kilometers is 2 to 5.
If two cities are 16 cm apart on the map, what is the actual distance in kilometers between the two cities? You can use a double number line diagram to help you solve.
Answer: 40 kilometers
Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.
