Answer:
[tex]V=6.66\ ft^3[/tex]
Step-by-step explanation:
The perimeter of the square base of a pyramid = 7.3 ft
The height of the pyramid, h = 6ft
The perimeter of a square is given by :
P = 4s, s is the side of square
7.3 = 4s
s = 1.825 ft
The volume of a pyramid is given by :
[tex]V=\dfrac{lbh}{3}[/tex]
Here, l = b = 1.825 ft
So,
[tex]V=\dfrac{1.825\times 1.825\times 6}{3}\\\\V=6.66\ ft^3[/tex]
So, the volume of the pyramid is equal to [tex]6.66\ ft^3[/tex].
Which bacteria sample (A or B) had a smaller initial population? What was that value?
Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
[tex]A(x) = 600[/tex] when [tex]x = 0[/tex]
For bacteria B, we have:
[tex]B(x) = 500(2)^x[/tex]
Substitute 0 for x
[tex]B(x) = 500(2)^0[/tex]
[tex]B(x) = 500*1[/tex]
[tex]B(x) = 500[/tex]
So; when x = 0
[tex]A(x) = 600[/tex] and [tex]B(x) = 500[/tex]
Because; 500 < 600
We can conclude that B has a smaller initial population of 500

-2/4= -0.5
therefore,
n= -0.5
Suppose it takes you 14 hour to drive to the movie theater at a rate of 40 mph. Your friend lives closer to the movie theater than you do. Which inequality represents the distance d (in miles) that your friend lives from the movie theater?
A. d < 10
B. d > 10
C. d > 40
D. d < 160
Answer: (d)
Step-by-step explanation:
Given
It takes 14 hours with 40 mph to reach the theatre
so, the distance traveled is given by
[tex]\Rightarrow d_1=40\times 14\\\Rightarrow d_1=560\ \text{miles}[/tex]
It is given that d is the distance from theatre to friend's house
So, d must be less than [tex]d_1[/tex] i.e.
[tex]d<d_1[/tex]
So, the most appropriate option out of the given is option (d) as d must be less than 560 and it is possible that it maybe less than 160.
Answer:
I believe you meant 1/4 instead of 14... it would be d. If you meant 14 then it would be 560 but there would be no answer choice.
Step-by-step explanation:

The probability of drawing a blue
marble from a bag containing
these marbles is į
If you replace the marble each time,
predict how many times a blue marble
will be chosen out of 50 draws.
[?] times
Enter
Answer:
25 times
Step-by-step explanation:
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times

The distance between City A and City B is 250 miles. On a certain wall map, this is
represented by a length of 1.5 feet. On the map, how many feet would there be between City C
and City D, two cities that are actually 450 miles apart?
Answer:
Step-by-step explanation:
1.5 feet x
====== = ======
250 miles 450
Multiply both sides by 450
1.5 * 450 x
====== =
250 miles
x = 2.7 feet
1 foot = 12 inches
0.7 foot = x
x = 12 * 0.7
x = 8.4 inches
Answer
Either 2.7 feet
or 2 feet 8 inches.
