Exact form: 1/4 Decimal form: 0.25
Answer:
The teacher will take 720 minutes or 12 hours to grade 32 reports.
Step-by-step explanation:
32 reports= x
4 reports= 90 minutes
Cross multiply method
90*32= 4x
2880= 4x
x= 720
The teacher will take 720 minutes or 12 hours to grade 32 reports.
Hope this helps!

Answer:
042
Step-by-step explanation:
The first clue tells you the possibilities are ...
6__, _8_, or __2
The second clue eliminates 6__ and tells you the possibilities are ...
18_, _81, 1_2, 48_, _42
The third clue tells you two of the correct digits are 0 and 2, since 6 has already been eliminated by the first two clues. This only leaves 042.
042 is consistent with the last 2 clues.
The 3-digit key is 042.
Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
Answer:
Step-by-step explanation:
We have been given a polynomial 
and we are supposed to simplify our polynomial.
We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.
We can see that 16, 6 and 4 has 2 as their greatest common factor.
The greatest common factor of 
is r.
The greatest common factor of 
is t.
So the greatest common factor of the terms of our expression will be 
.
Let us factor out from our given polynomial.
As we can not factor our expression more, therefore, we will get after simplifying our polynomial.
