Im stuck on question 43

Answers

Answer 1

Answer: Ok, first things first... No, she did not do the problem correctly. This question has everything to do with order of operations which says the parentheses are the first thing to be done, followed by exponents, multiplication, division, addition, and subtraction... PEMDAS. Now, technically, her first operation that she performed was incorrect because she did the exponent first, but this really doesn't affect the outcome, so we'll overlook it for now. Her next step was to go to the parentheses, but within the parentheses, she performed the wrong operation first... She should have multiplied 2 and 3, then added 4. Instead, she committed the fatal flaw in her math and added 4 and 2 then multiplied 3. As soon as that happened, the rest of the problem was incorrect because now she's adding and subtracting the wrong number.

The notes you made yourself on the side of the problem were exactly correct and if you followed them, you would have had the correct answer. The steps should have progressed like this...

2^3 + (4 + 2 * 3) -1 =
2^3 + (4 + 6) -1=
2^3 + 10 -1=
8 + 10 - 1=
18 - 1 = 17

Of course as you get better at solving this type of equation, you can combine steps. I wrote down each individual step so you could see more clearly what was going on. Have a good night!

Answer 2

Answer: The answer is no. Allsion did not follow the PEMDAS rule. She added 4+2 before she multipled 2 and 3 together in the parenthesis. This is how you get the real answer.
2^3 + (4 + 2 * 3) -1
8 + (4 + 6) -1
8 + (10) -1
18 - 1
17
17 is the final answer

a water tank holds 24,000 gallons how many hours will it take for two thirds of the water to be used if the water is used at an average rate of 650 gallons per day

Answers

In this question there are several important information's worth noting.Based on these information's the answer can be easily found. It is given that the total capacity of the tank is 24000 gallons. in 24 hours or in 1 day the amount of water used is 650 gallons. The question requires us to find the time it will take to use 2/3 rd of the water in the tank.
then
2/3 rd water in respect to total water in tank = (2/3) * 24000
= 16000
So 2/3 rd water of full tank is equivalent to 16000 gallons.
Now
650 gallons of water is used in = 24 hours
So
16000 gallons of water will be used in = (24/650) * 16000
= 590.77 hours
So it will take 590.77 hours to consume 2/3rd of the total water present in the tank.

326 people were in a tour group. Six buses were completely filled and 8 people chose to walk. How many people did the bus hold?

Answers

Answer:

The Total Capacity per bus is 53 people.

Step-by-step explanation:

To work this out you would first minus 8 from the total to find out how many actually went on the bus, and so we do not count the people walking. Then as you know there are six busses you would divide that new total by 6 to find the capacity per bus.

1) Minus 8 from 326.

$326-8=318$

2) Divide that by 6.

$318/6=53$

3) Total capacity.

The Total Capacity per bus is 53 people.

This shows that the total capacity per each bus is 53 people.

Step-by-step explanation:

take the number of people of tour group which is 326 and subtract with the number of people who choose to walk which is 8 and finally the answer is 318 people in the bus hold

I don’t get this. Can any help me

The average is the sum of the observations divided by the count.

So the sum of the observations is the count times the average.

So the 9 teachers together make 9(1000)=$9000 per week. The 20 staff (9 teachers + 11 aps) makes 20(1275)=25500.

So the 11 aps must make 25500-9000=16500

So the mean ap salary is 16500/11 =$1500 per week

Clearly management is where it's at.

Check: (1500*11+1000*9)/20 = 1275 good

Sunil receives 20% discount on a concert ticket that costs $75.If Sunil pays $3.30 in sales tax on the discounted ticket, what is the sales tax rate?

Answers

The sales tax rate is 5.5%

Step-by-step explanation:

First of all we have to calculate the ticket price with discount

Given

Ticket cost = c = $75

Discount = 20%

The discounted price will be:

$Discount= 20\%\ of\ 75\n=0.20*75\n=\$15$

The discounted price will be:

$Discounted\ Price = Ticket\ price - Discount\n= 75-15 = \$60$

Let r be the rate of sales tax

Then as given

$3.30 = r\%\ of\ 60\n3.30 = 60r\nr=(3.30)/(60)\nr = 0.055\nr = 0.055*100 = 5.5\%$

Hence,

The sales tax rate is 5.5%
