Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth
Mean: _ minutes
Median: __ minutes
Answers
Answer:
mean: 65
median: 9
Step-by-step explanation:
You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.
At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a teacher spent

than twice the number of hot lunches the teacher bought.
Which system of equations can be used to find c, the number of cold lunches, and h, the number of hot lunches, the
teacher bought during the school year?

A large pizza at Palanzio's Pizza starts at $6.80 with a $0.90 charge per extra topping. A large pizza a Guido's Pizza starts at $7.30 with a $0.65 charge per extra topping. How many toppings will need to be added for the price of the pizzas to be the same?
Answers
Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30

Mary wants to do a cheesecake. She needs 4 1/2 cups of sweet cream. She knows that 1
cup = 8 ounces How many ounces does she need?
Plsss 50 points!?
Answers
Answer:
36 ounces
Step-by-step explanation:
If 1 cup equals 8 ounces, you would multiply 4 1/2 by 8. 8 x 4 is 32 (ounces), and half of 8 is 4, so 4 ounces. You would then add 32 and 4 together to get your answer. Hope this helps!!
Answer:
She needs 36 ounces.
Step-by-step explanation:
4 1/2=9/2
1/8=(9/2)/x
cross product
8(9/2)=1*x
72/2=x
x=36

Step-by-step explanation:
Answer:
f = 2Step-by-step explanation:
f(x) = x2 ... when 'x' is equal to 5
So...
1.) Plug in 5 for the variable 'x'
f(5) = (5) * (2)
2.) Simplify both sides of the equation
5f = 10
3.) Divide both sides by 5
5f /5 = 10/5
f = 2

What are m∠1 and m∠2?
A.m∠1 = 30°, m∠2 = 35°
B.m∠1 = 35°, m∠2 = 30°
C.m∠1 = 65°, m∠2 = 60°
D.m∠1 = 85°, m∠2 = 80°
Answers
Answer:
B
Step-by-step explanation:
First find the third angle straight linear make 180° so
180°-115°=65°
So 80°+65°+X=180°..triangle measure 180°
145°+X=180
X=180-145
X=35°
The second one. Again straight linear measure 180° so
180°-115°=65°
65°+85°+ Y=180°
150°+ Y=180°
X=180°-150°
Y=30°
