math question:
simon believes that 3^0 • 3^2 is equal to 1 because 0 • 2 = 0 and any number raised to a power of 0 is 1. Is Simon correct? Justify your response.
Answers
Answer:
Simon is incorrect
Step-by-step explanation:
3^0 is not 0, it is 1.
A way of thinking about this is if to get from 3^2 to 3^1, you need to divide by 3, then to get from 3^1 to 3^0 you need to divide by 3 again. 3 divided by 3 is 1.
This means 3^0*3^2=1*9=9
1*6=6 not 1
simon's wrong but he is right when he says any number raised to a power of 0 is 1 and that 0*2=2 but here its 1*6=6 not 0 or 1*2=2

Answers
Answer:
$9.75
Step-by-step explanation:
Here are two ways of solving this:
Method 1) calculate 35% of original price and subtract from original price
original price: $15
discount rate: 35%
amount of discount: 35% of $15 = 0.35 * $15 = $5.25
final price = original price - amount of discount = $15 - $5.25 = $9.75
Method 2) calculate the percent the discount amount is, and calculate the amount
original price = $15 = 100% of original price
discount rate = 35%
Since the discount rate is 35%, then 100% - 35% = 65%, meaning the sale price is 65% of the original price.
final price = 65% of $15 = 0.65 * $15 = $9.75
Answer: $9.75

Sally paid $1.50 for pounds of apples at the Grocery Mart. Fred paid $1.95 for 3 pounds of apples at the Corner Fruit Stand. How much did Sally pay per pound of apples? (enter in the format of money, do not use the $ sign) Answer value'
Answers
Part A: Sally paid less money per pound than Fred did
Part B: John paid $3.58 for 5.5 pounds of apples at the Grocery Mart
Part C: y = 0.65x
Step-by-step explanation:
Part A:
Sally: 1.5/2.5 = x/1
cross multiply: 2.5x = 1.5*1
simplify: 2.5x = 1.5
divide both sides by 2.5: x = 0.6
Fred: 1.95/3 = x/1
cross multiply: 3x = 1.95*1
simplify: 3x = 1.95
divide both sides by 3: x = 0.65
Fred paid 65¢/pound while Sally paid 60¢/pound
Part B:
price/pound*amount John bought: 0.65/1 = x/5.5
cross multiply: 1x = 0.65*5.5
simplify: x = 3.575
Part C:
y = 0.65x

You've decided you want a plant for your room. At the gardening store, there are 444 different kinds of plants (tulip, fern, cactus, and ficus) and 444 different kinds of pots to hold the plants (clay pot, plastic pot, metal pot, and wood pot).
If you randomly pick the plant and the pot, what is the probability that you won't get a clay pot or a cactus?
Answers
Answer:
56.25%
Step-by-step explanation:
First, we need to find the total number of possible outcomes. We do this by multiplying the total number of plants by the total number of pots like so...
4 * 4 = 16 outcomes
Now we need to do the same but removing the cactus and clay pot from the list...
3 * 3 = 9 outcomes.
Now, to find the probability we need to divide the number of outcomes that do not include cactus and clay pot by the total original number of outcomes.
9 / 16 = 0.5625 or 56.25%
Finally, we can see that the probability of not getting a clay pot or cactus is 56.25%

Janelle has a babysitting job for the sunumer. She works from 7 AM to 2 P.M. with a 30-minute, unpaid break in the middle of the day. She is paid $4.50 per hour. How much money does Janelle make in 5 days?
Answers
Answer: $146.25
Step-by-step explanation:
To solve the question, we need to first calculate the number of hours between 7 AM to 2 P.M which is 7 hours but we are told that there is a 30 minutes break. Therefore, he works for 6 hours 30 minutes which is 6 1/2 hours.
She's paid $4.50 pee hour, therefore the amount paid per day will be:
= 6 1/2 × $4.50
= 6.50 × $4.50
= $29.25
The amount that she'll make in 5 days will be:
= $29.25 × 5
= $146.25
