Answer:
27.27cm²
Step-by-step explanation:
∅=125° r=5m
A=∅/360×πr²
A=125/360×3.142×5²
A=27.27cm²
Answer:
Mode- yellow
Number of 2nd graders- 17
Step-by-step explanation:
The mode is the variable with the largest value.
Yellow is the mode because the most students voted for it.
To find the number of 2nd graders, add up all of the dots.
1 + 3 + 4 + 6 + 3 = 17
There are 17 students
Answer:
8
Step-by-step explanation:
first, 70-79 have 3 students
then 80-89 have 5 students
Answer:
Step-by-step explanation:
We'll solve this with a system of equations. The first equation says that K's shares plus I's shares total 270; therefore,
K + I = 270
The second equation talks about the ratios of their shares.
2/5 I = 1/2 K We'll solve for K by multiplying both sides by 2:
4/5 I = K Now we'll sub that in for K to the first equation:
and
and
Now we'll solve for I, the number of shares that Ikedi has. Multiply both sides by 5 to get
then divide both sides by 9 to get

Ikedi has 150 shares. Sub that back into the first equation to solve for K:
K + 150 = 270 so
K = 120
