100 x 9 = 900
so
900 / 100 = 9
Answer:
4 pieces with 3 sides
2 pieces with only the top
Step-by-step explanation:
First we need to determine how many squares
9/3 = 3
12 /3 = 4
3*4 = 12
There will be 12 pieces of cake
There are 4 corners
They will have frosting on the top and two sides for 3 total sides
There will be 2 pieces will be in the middle with only the top frosted
Answer:
y
=
4
(
1
2
)
x
Explanation:
An exponential function is in the general form
y
=
a
(
b
)
x
We know the points
(
−
1
,
8
)
and
(
1
,
2
)
, so the following are true:
8
=
a
(
b
−
1
)
=
a
b
2
=
a
(
b
1
)
=
a
b
Multiply both sides of the first equation by
b
to find that
8
b
=
a
Plug this into the second equation and solve for
b
:
2
=
(
8
b
)
b
2
=
8
b
2
b
2
=
1
4
b
=
±
1
2
Two equations seem to be possible here. Plug both values of
b
into the either equation to find
a
. I'll use the second equation for simpler algebra.
If
b
=
1
2
:
2
=
a
(
1
2
)
a
=
4
Giving us the equation:
y
=
4
(
1
2
)
x
If
b
=
−
1
2
:
2
=
a
(
−
1
2
)
a
=
−
4
Giving us the equation:
y
=
−
4
(
−
1
2
)
x
However! In an exponential function,
b
>
0
, otherwise many issues arise when trying to graph the function.
The only valid function is
y
=
4
(
1
2
)
x
Given:
6 male professores
9 female professores
5 male teaching assistants
6 female teaching assistants
Sol:.
N (professors)
N(Male)
N(professors and male)
N(professors OR male) = N(professors) + N(males) -N(professor OR male)
N(People to choose from)
Then probablitiy is:
Then the probability is 10/13
Hello!
The answer for #1. is 4 centimeters, because it is the only reasonable answer.
The answer for #2. is 1 millimeter, because the tick is smaller than the penny, which is smaller than any of the other lengths.
I hope this helped :))
