No, the inscribed angle is simply half the central angle

Helen is helping plan a trip for three classes at her son's school. School rules say that classes on trips must have 1 adult for

seraphim [82]

So first I saw that u need 1 adult with every 6 children so I did 6*4 and got 24. From that I got 4 adults with 2 leftover children. For the other class which has 28 children, u would still need 4 adults. Now since u said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.

One month ruby worked 8 hours more than Issac,and Shetland worked 4 times as many hours as ruby. Together they worked 136 hours.

Natalka [10]

R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked

ruby worked 8 more than issac
r=8+i

shetland worked 4 times as many as ruby
s=4r

total they worked 136
r+i+s=136

so

we gots
r=8+i
s=4r

for r=8+i
solve for i
minus 8 both sides
r-8=i

so

r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24

sub back

r-8=i
24-8=i
16=i

s=4r
s=4(24)
s=96

ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours

Mallory and Aimee save money for summer camp. They both plan to save the same amount of money. Mallory has 35$ and plans to save

Mrrafil [7]

Answer:

0.857 weeks

Step-by-step explanation:

Using the information provided we can create the following equations for the total amount Mallory (M) and Aimee (A) will save after x number of weeks...

M = 35 + 15x

A = 5 + 50x

Now we would need to make both of these equations equal one another and solve for x to calculate after how many week both Aimee and Mallory will have saved the same amount of money

35 + 15x = 5 + 50x ... subtract 5 and 15x from both sides

30 = 35x ... divide both sides by 35

$\frac{30}{35}$ or 0.857 = x

Finally, we can see that after 0.857 weeks both Mallory and Aimee will have saved the same amount of money.

*** The process provided is correct but I believe that the actual values for Aimees savings should be $50 and plans to save $5 a week, this would make the final result 1.5 weeks which would make more sense***
