44 students in Mrs. Vitale's class read 11 books
<h3>Ratio and proportions</h3>
Let the number of students that read 11 books in Mrs. Vitale's class be x
If One fourth of the students in Mrs. Vitale's class read 11 books, then
1/4 x = 11 books
x = 11 * 4
x = 44
Hence 44 students in Mrs. Vitale's class read 11 books

<u>Statements</u>
<u>case 1)</u> x = 63
we know that
m∠x°=°-------> by corresponding angles
therefore
the statement case 1) is True
<u>case 2)</u> y = 47
we know that
therefore
the statement case 2) is False
<u>case 3)</u> z = 117
we know that
--------> by supplementary angles
therefore
the statement case 3) is True
<u>case 4)</u> y + z = 180
we know that
therefore
the statement case 4) is False
<u>case 5)</u> x + z = 180
we know that
therefore
the statement case 5) is True
Hence
<u>the answer is</u>
Answer:
area after 8 years is 2156km²
Step-by-step explanation:
Area of forest=4900 km²
decrease in area in 1 year=4900km² × 7%
decrease in area in 1 year= 343km²
decrease area in 8 years=343km² × 8
=2744km²
Remaining area= (4900-2744)km²
=2156km²
