The perimeter of a square is the sum of all its sides' lengths
That means: perimeter =4*(7m+1)/3
Answer:
To know what is the average of it
Step-by-step explanation:
We know that
[the area of composite figure]=[area of rectangle]+[area of a half circle]
[area of rectangle]=b*h
where
b=the base
h=the height
[area of rectangle]=b*h--------> 4.1*8.6---------> 35.26 cm²
[area of a circle]=pi*r²
where
r=the radius
r=4.1/2-------> 2.05 cm
the figure is a half circle
then
[area of a half circle]=pi*r²/2--------> pi*2.05²/2--------> 6.60 cm²
[the area of composite figure]=35.26+6.60--------> 41.86 cm²
the answer is
41.86 cm²
Answer:
Step-by-step explanation:
As an improper fraction
Answer:
25%
Step-by-step explanation:
Mrs. Loar has to grade 75 papers. Mrs. Holt is helping her grade. Mrs. Loar graded 60 papers and Mrs. Holt graded the rest.
Hence, the amount of papers Mrs Holy graded is = 75 - 60
= 15 papers
What percent of the papers did Mrs. Holt grade?
This is calculated as:
15/60 × 100 = 25%
Hence, Mrs Holy graded 25% of the papers
