Which expression gives the volume of a sphere with radius 8?A. 4(83)
B. (82)
C. (83)
D. 4(82

Answers

Answer 1
Answer: Given:
radius = 8

Volume of a sphere = 4/3 * π * r³

V = 4/3 * 3.14 * 8³
V = 1.33 * 3.14 * 512
V = 2,138.21 cubic unit
Answer 2
Answer: The volume of a sphere is (4/3)π(r^3)

Here r = 8

Then the expression for this sphere is 4π(8^3)/3 = 4*1.05 (8^4) ≈ 4(8^3)

the ratio of red marbles to green marbles is 3 to 5. which situation follows this ratio? 70 red marbles and 42 green marbles 9 red marbles and 24 green marbles 51 red marbles and 85 green marbles 30 red marbles and 18 green marbles

Answers

3/5 = 51/85

Therefore, 51 red marbles and 85 green marbles follows the required ratio.

Answer with explanation:

Ratio of red marbles to green marbles is equal to (3)/(5)

Now starting from Options given

1.(70)/(42)=(5)/(3)\n\n2.(9)/(24)=(3)/(8)\n\n3.(51)/(85)=(3)/(5)\n\n4.(30)/(18)=(5)/(3)\n\n\text{Option C}\rightarrow (51)/(85)

If 14 is 35% of a value, what is that value?

Answers

Find the value at 1% by taking the number and dividing by its percent:
14/35 = 0.4
Find the value at 100% by multiplying the 1% value by 100:
0.4 x 100 = 40
40 is the answer

If 2x^2 + 6x = 36, what are the possible values of x ?

Answers

The possible values of x for 2\cdot x^(2)+6\cdot x = 36 are x_(1) = 3 and x_(2) = -6.

The expression2\cdot x^(2)+6\cdot x = 36 is equivalent to the expression2\cdot x^(2)+6\cdot x -36 = 0, which represents a second orderpolynomial, that is, a polynomial of the form:

y = a\cdot x^(2)+b\cdot x + c(1)

Where a,\,b,\,c are coefficients.

The possible values of x represents all possible roots of x, which are found analytically by the quadratic formula:

x = \frac{-b\pm \sqrt{b^(2)-4\cdot a\cdot c}}{2\cdot a}(2)

If we know that a = 2, b = 6 and c = -36, then all possible values of x are, respectively:

x_(1) = 3, x_(2) = -6

The possible values of x for 2\cdot x^(2)+6\cdot x = 36 are x_(1) = 3 and x_(2) = -6.

the slope of a line is –2 and its y-intercept is (0, 3). what is the equation of the line that is parallel to the first line and passes through (2, 2)? a. y=4/3x - 3/2 b. 6x-4y=-8 c. y=3/4x 1 d. 4x – 2y = –12

Answers

Parallel lines has equal slope.
Required equation is (y - 2)/(x - 2) = -2 => y - 2 = -2(x - 2) => y - 2 = -2x + 4 => 2x + y = 6
