Answer:

The answer is D - 382

Step-by-step explanation:

The volume of a sphere can be calculated using this simple formula:

V = 4/3 x 3.14(pi) x r cubed(to the third)

So, V = 4/3 x 3.14 x 4.5 cubed

V = approximately 382

Answer:

382

Step-by-step explanation:

Radius = 4.5 inches

Note that the shape of the ball is a sphere

Volume of sphere = 4/3 πr³

Volume = 4/3 x 3.14 x 4.5 x 4.5 x 4.5

Volume = 1144.53 ➗ 3

Volume = 381.51 cubic inch

Approximately 382 cubic inch

Hence, second option is the true option. {Result of spin, card color}

{Green, Purple} {Yellow, Purple} {Purple, Purple }

{Green, Green} {Yellow, Green} {Purple, Green}

Step-by-step explanation:

It is given that:

A spinner with 3 equal sectors is shown in the figure. The colors Green, Yellow, and Purple are marked on it.

Two cards are shown on the right side. Their colors are Purple and Green.

The table that identifies the sample space of spinning the spinner and then selecting a card is:

{Result of spin, card color}

{Green, Purple} {Yellow, Purple} {Purple, Purple }

{Green, Green} {Yellow, Green} {Purple, Green}

( Since in rest of the options the red color in the sample space but there is no card or no such color in the spin which is red)

Solve the inequality.

Stells [14]

Answer:

x ≤ - 5

Step-by-step explanation:

Given

- 2x - 1 ≥ 9 ( add 1 to both sides )

- 2x ≥ 10

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x ≤ - 5

Answer:

The linear function is $y=50x+20$

The reasonable domain is $0\ hours \leq x\leq 2\ hours$

Step-by-step explanation:

Let

x ----> the time in hours

y ---> the distance in miles

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The slope is $m=50\ \frac{miles}{hour}$

The y-intercept is $b=20\ miles$

substitute

$y=50x+20$

Find the domain for x

For y=120 miles

Find the value of x

substitute the value of y in the linear equation and solve for x

$120=50x+20$

$50x=120-20$

$50x=100$

$x=2\ hours$

therefore

The domain is the interval [0,2]

$0\ hours \leq x\leq 2\ hours$
