Stephanie is cutting a pie. Stephanie's mother wants one fourth of the pie. The diameter is 20 cm.
What is the sector area of the pie her mother does not want?

Answers

Answer 1

Answer:

78.55cm^2

Step-by-step explanation:

Given data

DIameter of pie= 20 cm

Radius of pie= 10cm

Area of pie= πr^2

Area= 3.142*10^2

Area= 3.142*100

Area= 314.2 cm^2

Hence one fourth  of 314.2 cm^2 is

= 314.2/4

= 78.55cm^2

Therefore the area of the sector is 78.55cm^2

Step-by-step explanation:

the 3/5 is irrelevant for this problem, so ignore it

just focus on the -n

if n<0, the expression would be positive because negative*negative=positive

if n>0 the expression would be negative because positive*negative=negative, which is good

and it isn't 0 because 0*anything is 0 and 0 isn't positive or negative

Katie bought 2 one gallon bottles for a party. Her guest drank 5/4 gallons of juice. What is the fraction of juice leftover? Show a number line to explain

Answers

Answer:

3/4 gallons of juice

Step-by-step explanation:

Katie bought 2 one-gallon bottles for a party.

2 one-gallon bottles = 2-gallon bottles of juice

We are told that:

Her guest drank 5/4 gallons of juice.

The fraction of juice leftover is calculated as:

2 gallons of juice - 5/4 gallons of juice

2 - 5/4

Lowest Common Denominator = 4

2/1 - 5/4

= 8 - 5/4

= 3/4 gallons of juice

Therefore, the fraction of juice leftover is 3/4 gallons of juice

An arts academy requires there to be 5 teachers for every 125 students and 4 tutors for every 88 students. How many students does the academy have per teacher? per tutor? How many tutors does the academy need if it has 81 students? Pleaseee help​

Answers

Answer:

25 students peer teacher, 22 students per tutor, 4 tutors for 81 students

Step-by-step explanation:

You need to find the unit rate,

for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.

Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.
