Answer:113.1

Step-by-step explanation: The equation for volume of a sphere is (4/3)πr^3

r=.5 d so r=3. You plug it in and get (4/3)π * 27 because 3*3*3=27. From there you just multiply everything together because there is no adding subtracting or dividing left to do. You can then plug in plug in the equation (4/3)π * 27 into your calculator.

Answer:

V = 36 π cubic inches

Step-by-step explanation:

Volume of Sphere= (4/3) x pi x r^3

V= (4/3) x 3^3 x pi

V= (4/3) x 27 x pi

V= 36 pi

V = 36 π cubic inches

Hope this helps :)

Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute valu

dusya [7]

Inequalities are used to compare unequal expressions.

The actual comparison is: $\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

The temperatures are given as:

$\mathbf{Temperature = -3.5F,\ \ 5F,\ \ 1.5F,\ \ -0.5F,\ \ -2F,\ \ 2.5F,\ \ -4F}$

From the above list, we have:

$\mathbf{Day \ 1= -3.5F}$

$\mathbf{Day \ 2= 5F}$

By comparison,

$\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

Using absolute values, the inequalities are:

$\mathbf{|-3.5| < |5|}$ or $\mathbf{|5| > |-3.5|}$

Hence, the actual comparison is:

$\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

What are the 3 angle measures in the triangle shown below

7nadin3 [17]

9514 1404 393

Answer:

B. 39°, 106°, 43°

Step-by-step explanation:

The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.

(3x +1) +(11x -4) +(5x -7) = 180

19x -10 = 180 . . . . . collect terms

19x = 190 . . . . . . . . add 10

x = 10 . . . . . . . . . . . divide by 19

__

Then the three angle measures are ...

3·10 +1 = 31
11·10 -4 = 106
5·10 -7 = 43

The appropriate choice is ...

B. 31°, 106°, 43°
