Answers
Answer:
False; True; True
Step-by-step explanation:
If the radius is 4, the area of the circle is
pi*r*r = pi * 4 * 4 = 16pi; The second statement is true.
The entire circle's "angle" is 2pi, so the sector takes (2pi/3) / 2pi of it all, equal to 1/3 of the entire circle - hence the area of the sector is
16pi * 1/3 = 16pi/3; the first statement is false
The length of the entire circle is 2 * pi * r = 2 * pi * 4 = 8pi
The sector is 1/3 of that, so 8pi/3; the third statement is true.

Troy has an album that has 400 hockey cards. Each page of the album holds 4 hockey cards. If 19% of the album is empty, how many pages are filled with hockey cards?
Answers
Answer:
81 pages
Step-by-step explanation:
From the information given :
Total hockey cards = 400
Cards per page = 4
Number of pages = 400 /4
Number of pages in album = 100
% of album which is empty = 19%
% filled = 100 - 19 = 81%
81% of 100
0.81 * 100 = 81 pages

9 1/2 yards x 19 1/4 yards
Answers
Answer:
(9 1/2) * (19 1/4) = 1463/8 = 182 7/8
Step-by-step explanation:
Conversion a mixed number 9 1/2
to a improper fraction: 9 1/2 = 9 1/2
= 9 · 2 + 1/2
= 18 + 1/2
= 19/2
To find a new numerator:
a) Multiply the whole number 9 by the denominator 2. Whole number 9 equally 9 * 2/2
= 18/2
b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19
c) Write a previous answer (new numerator 19) over the denominator 2.
Nine and one half is nineteen halves
Conversion a mixed number 19 1/4
to a improper fraction: 19 1/4 = 19 1/4
= 19 · 4 + 1/4
= 76 + 1/4
= 77/4
To find new numerator:
a) Multiply the whole number 19 by the denominator 4. Whole number 19 equally 19 * 4/4
= 76/4
b) Add the answer from previous step 76 to the numerator 1. New numerator is 76 + 1 = 77
c) Write a previous answer (new numerator 77) over the denominator 4.

The cost of an article including 15% for taxes is ghc ghc138. What is the cost of the article without taxes
Answers
Answer:
Cost of article before tax is 120.
Step-by-step explanation:
It says cost of an article including 15% tax is 138.
So, let the cost of article without tax as 'x'
So, we can set up equation as
x+15%(x)=138
Simplify it
x+0.15x=138
1.15x=138
Divide both sides by 1.15
x=120
So, cost of article before tax is 120.

A single die is rolled one time What is the probability of rolling an even number or a 5?
Answers
Answer: 4/6 or 2/3
Step-by-step explanation:
Step-by-step explanation:
Total sample space , n(s) = 6
Favourable cases of rolling even number,
n(e) = 3
Favourable cases of rolling 5 , n(f) = 1
Probability of rolling an even number or a 5 is
= p(e) + p(f)
= n(e) / n(s) + n(f) / n(s)
= 3 / 6 + 1 / 6
= 4 / 6
= 2/3
