Answers

If u add 125 times 8 it will equal 1000
becouse
$8*125=1000$
then
$(1000)/(8) =125$
you also can combine it (if this is what are you looking for..)
$888+88+8+8+8=1000$
or any other combination like:
$88+888+8+8+8=1000$
or:
$8+8+888+8+88=1000$

Alex received two job offers. He is not sure whether he should take a job at the movie theater that's close to his house and pays $8.50 per hour, or if he should take the job at a grocery store that pays $9.00 per hour, but is a thirty-minute drive away. Use the PACED decision process to decide what Alex should do. Show each step.

Answers

PACED decision making model
P - identify the problem
A - identify the alternatives
C - determine criteria
E - evaluate alternatives
D - make a decision

Problem: What job to take?
Alternatives:
1st job: movie theater ; 8.50/hr ; near his house or walking distance
2nd job: grocery store ; 9.00/hr ; 30 minutes travel
Criteria:
travel time and travel cost
Evaluate:
1st job: walking distance, no traffic worries nor fuel expenses
2nd job: 30 minutes travel time, consider traffic, fuel expenses
Decision:
It is more practical to accept the job in the movie house. Even though it is only 8.50 per hour, travel expenses is 0 and there is no difficulty in going to work.

Answer:

Movie Theater

Step-by-step explanation:

P - identify the problem

A - identify the alternatives

C - determine criteria

E - evaluate alternatives

D - make a decision

1st job; $8.50 an hour

2nd job; $9 an hour

1st job; walking distance, no fuel or car expenses

2nd job; 30 minutes away, need to pay for a bus or gas for a car

I say he should get the job at the movie theater, its closer so he doesnt need to spend money on gas or for a way to get to the other job. It's only $.50 more for the other job but he would cost more for a way to get there.

Dwayne is selling hamburgers and cheeseburgers. He has 100 burger buns. Each hamburger sells for $3, and each cheeseburger sells for $3.50. Which system of inequalities represents the number of hamburgers, h, and the number of cheeseburgers, c, he must sell to have sales of at least $80? h + c ≤ 80 3h + 3.5c ≤ 100 h + c ≤ 80 3h + 3.5c ≥ 100 h + c ≤ 100 3h + 3.5c ≤ 80 h + c ≤ 100 3h + 3.5c ≥ 80

Answers

Given:
hamburger = h ; sells for 3
cheeseburger = c ; sells for 3.50
100 burger buns

h + c = 100

3h + 3.5c > 80 last option.

Answer:

Its D

PLEASE HELP! How do I solve this problem?

Answers

The toughest part of this problem could be deciding what names to give the quantities of one-Euro and two-Euro coins.

-- I called the number of one-Euro coins ' N '.
Each of them is worth 1 Euro, so all ' N ' of them are worth ' N ' Euros.

-- I called the number of two-Euro coins ' T '.
Each of them is worth 2 Euros, so all ' T ' of them are worth ' 2T ' Euros.

-- The total number of coins in Penny's pocket is (N + T), and it says there are 11.

-- Their total value is (N + 2T), and it says the total value is 18.

So now you have two equations, with two unknowns.

   N + 2T = 18
   N + T = 11

Subtract the bottom equation from the top one, and you get:

(N - N) + (2T - T) = (18 - 11)

   T = 7    (there are 7 two-Euro coins in her pocket)

That right there is the answer to the question, so you don't need to go
any farther. But if you wanted to, you could also figure out how many
one-Euro coins there are in her pocket.
