Density = mass / volume.
Volume = Final reading - Initial reading = 7 - 2 = 5 cm^3
Hence,
D = 25 / 5 = 5 g/cm^3
<span>Remember, cubic centimeters is a volume unit (the same volume as 1 milliliter)</span>
Hope that helped!

Evaluate 2(8 + t)3 – 6 when s = 3 and t = 2.<br><br> +) The value of the expression is 250
siniylev [52]

Step-by-step explanation:

s = 3 and t = 2

= 2(8 + t)³ - 6

= 2(8 + 2)³ - 6

= 2(10)³ - 6

= 2(1.000) - 6

= 2.000 - 6

= 1.994

NikAS [45]
<span><span>1.       </span>The music hall has 20 boxes :
=> on thurs 2/5 were occupied
=> on friday 2/4 were occupied
=> and on saturday 8/10 were occupied.
Let’s find out which day has the most occupied space of the music hall.
2/5 + 2/4 + 8/10 = 6/20 + 7/20 + 10/20
Thurs 2/5 were occupied
=> 6/20 = 0.3
=> 20 * 0.3 = 6 boxes
Friday 2/4 were occupied
=> 7/20 = 0.35
=> 20 * 0.35 = 7 boxes
Saturday 8/10 were occupied.
=> 10/20 = 0.5
=> 20 * .5 = 10 boxes
Thus, during Saturday has the most number of occupied boxes.</span>

PLEASE HELP THIS IS TIMED!!!! I WILL GIVE BRAINLIESTTTTTT
jekas [21]

Answer

Given: Sorry the images are at the bottom.

To find:

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

Part B: Which function has a greater y-intercept? Justify your answer.

Solution:

On inspection of values of x and f(x) it is clear that f(x) is a linear function

i.e.

1)Slope of f(x) and y-intercept of f(x):

Convert the function in slope intercept form and calculate the slope.

Slope intercept form:

Here,

Slope of f(x)=1,

y-intercept of f(x)=(0,0)

2) Slope and y-intercept of g(x):

Slope of g(x)=7

Y-INTERCEPT of g(x) =(0,2)

Part A:

Slope of f(x) is 1 and slope of g(x) is 7.

Part B:

g(x) has a greater y-intercept.

Hope it helps you.
