7. A teacher calculated her students' grades for the last grading period. The circle graph shows the letter grades and the percentage of students receiving that letter grade for the grading period. Student Grades D (70-74) 16% B (80-89) 48% C (75-79) 12% A (90-100) The teacher has a total of 125 students. How many students earned an A (90-100)?​

i got 19.5 or 20 but for my test the closest number was 30

Step-by-step explanation:

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.

we are given scale of 2 units.

on graph paper the space is 2.5 cm.

length of glass = 8 units.

8 units = 2 units +2 units +2 units +2 units.

each 2 unit is = 2.5cm.

therefore,

8 units = 2 units +2 units +2 units +2 units = 2.5+2.5+2.5+2.5= 10cm.
