Answer:

A. 2,144.66 in³

Step-by-step explanation:

The formula for the volume of a sphere is ...

V = (4/3)πr³

The radius is half the diameter, so this can be written in terms of diameter as ...

V = (4/3)π(d/2)² = (π/6)d³

For a diameter of 16 inches, the volume is ...

V = (π/6)(16 in)³ ≈ 2,144.66 in³

Answer:

Step-by-step explanation:

f(x) means y, it is equal to the value of y, so f(x) = y

so, f(1) means to find the value of y when the value of x is 1, and that is 7, since 7 is the value of y indicated when the value of x is 1.

I hope this is helpful.

10-root18/root2 = a+broot2

Sauron [17]

Step-by-step explanation:

$\frac{10 - \sqrt{18} }{ \sqrt{2} } = a + b \sqrt{2}$

$\frac{10}{ \sqrt{2} } + \frac{ - \sqrt{18} }{ \sqrt{2} }$

$5 \sqrt{2} + ( \frac{ - \sqrt{18} }{ \sqrt{2} } ) \times \sqrt{2}$

$a = 5 \sqrt{2}$

$b = \frac{ - \sqrt{18} }{ \sqrt{2} }$

Help please will mark brainless 25 points due today

harkovskaia [24]

here's the solution,

we know that, sum of measures of each interior angle of a triangle = 180°

Figure 1.

=》

$40 + 32 + 9x + 9 = 180$

=》

$81 + 9x = 180$

=》

$9x = 180 - 81$

=》

$x = \frac{99}{9}$

=》

$x = 11$

Figure 2. 

=》

$42 + 63 + 4x + 15 = 180$

=》

$120 + 4x = 180$

=》

$4x = 180 - 120$

=》

$4x = 60$

=》

$x = \frac{60}{4}$

=》

$x = 15$

Figure 3.

=》

$45 + 45 + 3x - 21 = 180$

=》

$3x + 69 = 180$

=》

$3x = 180 - 69$

=》

$3x = 111$

=》

$x = \frac{111}{3}$

=》

$x = 37$

Answer:

disagree

Step-by-step explanation:

The interquartile range is a measure of how spread out values are in a data set.

It doesn't actually consider the values, it is found by finding the range between the Q1 / 25th percentile and the Q3 / 75th percentile --and a "range" is found by finding the difference between these two numbers (by subtracting).

So, the weather could have been something like:

79 79 79 80 81 81 83 85 96 97

79 79 79 80 81 | 81 83 85 96 97

meaning that the interquartile range is 6, but these temperatures are not low

(if you want me to explain how to find the interquartile range more thoroughly, please let me know)
