You  get a $50 discount because 300-250 = 50. Oringinally, you would of had to pay $300, but the store took of $50 so that you would only have to pay $250

If 80% is 72 marks what is full marks can someone tell me the answer please

80% = 0.8

100% = 1

0.8 = 72

1 = x

0.8* x = 72 * 1

x = 72 / 0.8 = 90

0.8 * 90 = 72

80% * 90 = 72

QUESTION POSTED AT 06/12/2019 - 02:46 PM

Four coins are tossed several times. Which of the following represents the outcome on a coin that may not be fair? 1st coin is tossed 50 times and gives 24 heads and 26 tails. 2nd coin is tossed 250 times so that P(heads) = 0.25. 3rd coin is tossed 16 times and gives P(tails) = 9/16 4th coin is tossed 25,000 times and gives 12,505 heads.


If a fair coin is tossed a great many times, you
expect the results to be 50-50 or close to it.

First coin:  24 and 26.   48%  and  52%. 

Second coin:  25%  and  75%

Third coin:  9/16  and  7/16.  56.25%  and  43.75% .

Fourth coin:  12,505  and  12,495 .  50.02%  and  49.98% .


If I'm betting my own jellybeans, then I would not go anywhere near
the second coin, and I'm not all that happy with the third coin either.

Bridget needs an actor. Actor A is offering her services for an initial $250 in addition to $50 per day. Actor B is offering her services for an initial $200 in addition to $60 per day. When will the two actors charge the same amount of money?

$250 + 50x = $200 + 60x

Get like terms on the same side using subtraction
250 -200 + 50x = 60x
50 + 50x - 50x = 60x -50x
50 = 10x     now divide by 10 and get 5 days.

Let's check

Day 1  Actor A is $250 + 50 = $300  Actor B = $200 + 60 = $260
Day 2 Actor A is $250 + 100 = $350  Actor B = $200 + 120 = $320
Day 3 Actor A is $250 + 150 = $400   Actor B = $200 + 180 = $380
Day 4 Actor A  is $250 + 200 = $450   Actor B = $200 + 240 = $440
Day 5  Actor A is $250 + 250 = $500    Actor B = $200 + 300 = $500

A used automobile dealership recently reduced the price of a used compact car by 6%. If the price of the car before discount was 18,400, find the discount and the new price

Answer:  Discount Price = $1104

New Price = $17296

Step-by-step explanation:

Given : A used automobile dealership recently reduced the price of a used compact car by 6%, which can be written as 0.06.

The price of the car before discount was 18,400.

Formula for Discount = Discount percentage× Original price

Then , Discount =0.06\times18400=\$1104

New Price after Discount = Original Price - Discount price

=\$18,400-\$1104=\$17296

Hence, Discount Price = $1104

New Price = $17296

A truck driver drove 300 miles in 6 3/4 hours. How many miles per hour did the driver drive?

Answer:

44.44 miles per hour.

Step-by-step explanation:

A truck driver drove 300 miles in 6\frac{3}{4} hours.

We have to calculate the speed per hour.

First we convert 6\frac{3}{4} hours to decimal form.

6\frac{3}{4} = 6.75 hours

∵ in 6.75 hours the driver drove = 300 miles

∴ in 1 hour he drove = \frac{300}{6.75} miles

                                = 44.44 miles

The truck driver drove 44.44 miles per hour.

QUESTION POSTED AT 06/12/2019 - 08:04 AM

If a store advertised a sale that gave customers a 1/4 discount,what is the fractional part of the original price that the customers will pay?

It's easy to explain this using numbers- Let's say you buy something that costs $16.  1/4 of that is $4.  16 - 4 = 12.  
12/16 = 6/12 = 3/4 

Another way of explain this is using subtraction with fractions: 
1 - 1/4 = 1/1 - 1/4 = 4/4 - 1/4 = 3/4 

Therefore the customers will pay 3/4 of the original part.

Maria is selling toys an flowers.The toys cost $12 an the flowers cost $10. She needs to make at least $300.

Maria needs to sell at last 14 flowers and 14 toys to get $308 

I will show you how it works:
x(12+10) = 300      you add 12 and 10 together
x(22) = 300            than 22 times x
22x = 300               now you divide 300 by 22, you will get 13.64, round it, 14
x = 14

Flowers : 10 times 14 = $ 140
Toys : 12 times 14 = $168     Now add them together.
Flowers and Toys = $308 

So this is how you get the answer

QUESTION POSTED AT 06/12/2019 - 07:40 AM

Mark wrote the highest score he made on his new video game as the product of 70x6,000. Use the associative and commutative properties to show how mark can calculate this product mentally

Answer:

70 × 6000 = 420000

Step-by-step explanation:

In this question, we need to write the product of two numbers 70 × 6000 using associative and commutative properties.

Two numbers are commutative if,

a × b = b × a

Two numbers are associative if,

(a × b) × c = a × (b × c)

Here, 70\times 6000=(7\times 10)\times (6\times 1000)

70\times 6000=7\times 10\times 6\times 1000

Using commutative property as,

70\times 6000=7\times 6\times 10\times 1000

Now using associative property as,

70\times 6000=42\times (10\times 1000)

70\times 6000=42\times (10000)

70\times 6000=420000

So, 70 × 6000 = 420000. Hence, this is the required solution.

300 is 5% of what number

At first I learned to do these equations as Part÷Whole=Percent÷100
Part(The portion)=300
Whole=X
Percent=5
So now you have
300÷X=5÷100
Set this up as a fraction and cross multiply.
Now you have 30,000=5x
Now divide both sides by 5 and you get x=6,000
6,000 is your answer.

A pair of pants with a marked price of $35.00 has a discount of 20%. How much is the discount? Can someone help me learn to do problems like this please?

When you see a "%" you need to ask " a percent of what"?

Here, it's a percent of the original prize, so the discount is 20% of the original prize, that is 20% of 35.

20% is also 20/100 or 1/5, so we can calculate this like this:

 \frac{1}{5} *35=7

so the discount is 7 dollars.
