D; 1 and 6 are being added together first then divided by 7, so need the parentheses around 1 and 6

1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> what is v?

Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

$1 \frac{1}{2} \\ = \frac{2 \times 1 + 1}{2} \\ = \frac{3}{2}$

In order to find the value of v, you have to substract 3/4 to both sides :

$\frac{3}{2} = v + \frac{3}{4}$

$\frac{3}{2} - \frac{3}{4} = v + \frac{3}{4} - \frac{3}{4}$

$v = \frac{3 \times 2}{2 \times 2} - \frac{3}{4}$

$v = \frac{6}{4} - \frac{3}{4}$

$v = \frac{3}{4}$

(Simplify your answer. Type an exact answer in terms of pi.)

So the formula for the volume of a sphere is 4/3 * (π * r³)

V = 4/3 * (π * 6³)

V = 4/3 * (π * 216)

V = 4/3 * 678.24

V = 904.78

Plz help with math and show your work

Inga [223]

26. 2x^2 +4x -10 = 0 (-4 + - (root(4^2 - 4*2*-10)))/2*2 =
(-4 + - (root(96)))/4
(-4 + (root(96)))/4 ≈ 1.45
(-4 - (root(96)))/4 ≈ -3.45

27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore x -2 = 0 x +3 = 0 x -5 = 0 so f(x) = 0 when x = 2, -3 or 5

28. It looks like it shows you how to do it
