Answer:
the atomic number
Step-by-step explanation:
the atomic number is the number of protons in the shell
1) we calculate the total cost of all items:
Total cost=27 * $1.25 + 5 *1.99$ + 1*1.5$=$33.75 + $9.95 + $1.5=$45.2
2)we express the total cost in cents:
$1=100 cents
$45.2=$45.2 * (100 cents /$1)=4520 cents.
3)we divide 4520 cents among the number of pupils
Each student will pay=4520 cents / 26 =173.84... cents≈174 cents.
Answer: Each student will pay 174 cents.
Point (-9,7) lies in quadrant II
Log base 10 (1/1000)
10^x = 1/1000
Log1/1000 = -3
Answer:

3 * 3 = 9 which covers for both triangles
each triangle is half of a square. so each triangle is 4.5 sq. units
add 21 with 9
21 + 9 = 30
