Answer:

16.39

Step-by-step explanation:

volume of sphere = (4/3) · 3.14(π) · r³

=> 2304 = 4/3 · 3.14 · r³

=> 2304 · 3/4 = 3.14 · r³

=> 1,728 = 3.14 · r³

=> r³ = 550.318

=> r = 8.19

diameter = 2 · r

=> diameter = 2 · 8.19 = 16.39

Help me please! I can't figure this out

First we need to look at the greatest and least points on each axis.

For x - the greatest is 2 and the least is -2 (that is the value of x for the points marked in the top left and right quadrants of the xy axis.

(Note that the points on the number line have a value for x of 1 & -1, but you need to look at highest value of points in all quadrants.)

For y - the greatest would be 3 and the least 0. Looking up and down the Y axis, you can see these intersections for the points given.

Now you need to find the D & R that is suitable for these values. We can only consider the first and last option because it correctly shows that the values for x & 7 must be between 2 & -2 and 0 and 3, The first one is incorrect because they have the D & R reversed. It is x that must be between 2 & -2 and y that must be between 0 & 3.

I hope you found this helpful.

mrs. li bought some crackers. she gave 30% of the crackers to her neighbor and ate 50% of the remaining crackers. mrs. li had 42

snow_tiger [21]

Answer:
She bought 120 crackers

Explanation:
Assume that the number of crackers she originally bought was x

We know that she gave her neighbor 30% of the crackers.\This means that:
amount left with her = x - 30%x
amount left with her = x - 0.3 x
amount left with her = 0.7x crackers

Now, we know that she ate 50% of that amount.
This means that:
she ate 50%(0.7x) = 0.5(0.7x) = 0.35x crackers
amount left with her = 0.7x - 0.35x = 0.35x crackers

Finally, we know that the number of crackers left with her is 42 crackers.
This means that:
0.35x = 42
x = $\frac{42}{0.35}$
x = 120 crackers

Hope this helps :)

Identify the domain and range of each of the graphs below. Domain: Range:

Anna11 [10]

Answer:

Domain → (-∞, ∞)

Range → (-∞, ∞)

Step-by-step explanation:

Domain of a function is defined by the x-values or input values of the graph.

Similarly, Range of the function is defined by the y-values or output values from the graph.

From the picture attached,

x - values for the line shown in the graph vary from negative infinity to positive infinity.

Therefore, Domain of the function will be → (-∞, ∞)

And for every x-value there is a y-value, so Range of the function will be same as domain (varying from negative infinity to positive infinity) → (-∞, ∞)
