Mr.Walden wrote the expression. He asked his students to write an equivalent expression of simplified form.

mafiozo [28]

Answer:

option D

Brianna

Step-by-step explanation:

Given in the question the expression wrote by Mr.Walden

$\frac{p^{-5} }{q^{0} }$

To write the simplified form of this expression we will use negative rule of exponent

$b^{-n}$ = 1 / $b^{n}$

$q^{-5} = \frac{1}{q^{5} }$

so,

$\frac{1}{q^{5} x q^{0} }$

$\frac{1}{q^{5} p^{0} }$

Only Brianna wrote right simplification of the expression written by Mr.Walden

Margie is packing 108 small boxes into a large carton. the small boxes will fill all of the space inside the large carton. Each

just olya [345]

2 inches wide
that means that the height of the large carton is 2 inches

find the volume of the carton
V=108 times volume of small box
V=108 times 1 times 2 time s3
V=648 in^2

height is 2
V=LWH
648=LW2 (note, this is not LW^2 but 2 times LW)
divie both sides by 2
324=LW
legnth of base is less than 36
div
we just need to find the values of legnth and width such that LW=324 and L<36 and that L or W is divisible by 3 (since each box is 3 inches long)

so lets factor 324
324=2*2*3*3*3*3
group them and find possible values for legnth and width less than 36 and divsible by 3
possible values

(L,W,H) possible values are
(27,12,2)
(18,18,2)

the possible dimentions are
27 by 12 by 2 or
18 by 18 by 2

01:57:09 In a city, the distance between the library and the police station is 3 miles less than twice the distance between the

tester [92]

Answer:

Distance between the police station and the fire station be 4 miles

Step-by-step explanation:

Let distance between the police station and the fire station be x miles.

The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.

Distance between the library and the police station $=2x-3$

Also, distance between the library and the police station is 5 miles.

$2x-3=5\\2x=3+5\\2x=8\\x=\frac{8}{2}\\ x=4\,\,miles$

The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t^2 - 0.5t + 3.

Bingel [31]

The average rate of change (m) is the ratio of the change in function value to the width of the interval:
m = (f(6) - f(2))/(6 - 2)

To compute this, we need to compute f(6) and f(2).
f(6) = (0.25*6 -0.5)*6 +3.5 = 9.5
f(2) = (0.25*2 - 0.5)*2 +3.5 = 3.5
Then the average rate of change is
m = (9.5 - 3.5)/(6 - 2) = 6/4 = 1.5

The average rate of change is 1.5 thousand owners per year.

You are graphing rectangle ABCDABCDA, B, C, D in the coordinate plane. The following are three of the vertices of the rectangle:

vampirchik [111]

Answer:

The given coordinates of the vertices of rectangle ABCD are A(−2,2),B(4,2),C(4,−2).

We are to plot D on the graph.

Since ABCD is a rectangle, the abscissa of D will be that of A and the ordinate of D will be that of C.
