The question requires you skills in doing multiplication or division. Ratio and proportion would also do here.
The topic here is about conversion.
You are given that 100 cm = 1m
Then how about 13 m?
100 cm : 1 m = X : 13m
100 cm * 13m = 1m * x
1300 = 1m * X
X = 1300 cm
So 13m is equal to 1,300 cm
Answer:
9 1/4
Step-by-step explanation:
9.25-9=0.25
0.25 =1/4
9 1/4
(x-9)(x-3), because -9 and -3 make a sum of -12 and a product of +27
Answer: an arithmetic sequence
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
First, fill in 3 boxes of the table using the given information (blue numbers on the attached table)
"Of the 32 students that have a cell phone, 19 students do not have a tablet."
The top row of the table is students who have a cell phone. Therefore, place 19 in the box in this row that is in the "no tablet" column.
"Of the 70 students that have a tablet, 57 students do not have a cell phone."
The first column of the table is students who have a tablet. Therefore, place 57 in the box in the 2nd row of this column.
"11 students do not have a cell phone or a tablet."
Find the "no cell phone" row and the "no tablet" column and place 11 in the box that coincides.
We can calculate the blank totals using addition (shown by green numbers on the attached table)
- Total students with no cell phone = 57 + 11 = 68
- Total students with no tablet = 19 + 11 = 30
To calculate the number of students who have a cell phone AND a tablet:
⇒ Total students with a cell phone <em>minus</em> students with a cell phone but no tablet
⇒ 32 - 19 = 13
