Answer:
I can't add picture for some reason so u have to read explanation :(
Step-by-step explanation:
First, turn everything into an improper fraction.
you get 11/3 x 9/2 ÷ 5/4
Next, according to PEMDAS, you multiply first and you get
33/2. DIvide that by 5/4 so
33/2 ÷ 5/4
So you get 33/5 or as a mixed fraction, 6 3/5
<span>Alice
Correa bought three yards of cloth to make a dress
The cloth was on sale for 1.93 per yard.
Now, how much did Alice pay for the
cloth if the sales tax was 5%.
Let’ solve for the answer
=> 3 yard of clothes were both.
=> Price of clothes are 1.93 dollars per yard
=> then another sales tax is added which is 5%
=> 3 yards * 1.93 dollars = 5.79 dollars
=> 5.79 dollars * .05 = 0.2895
=> 5.79 + 0.2895
=> 6.08 dollars.

Answer:
3 t-shirts
Step-by-step explanation:
<u>Lets recap the information we will use from this problem:</u>
The ticket to the festival costs $87.96
T-shirts are $30.00
She is taking $200.00 to the festival
Now we can solve. First we will subtract the price of the ticket from the total amount of money she has.
$200.00 - $87.96 = $112.04
Now that she has payed for the ticket, we want to find out how many shirts she can buy with the remainder of her money. To find this, we will set up an equation like this:
(Amount of money left) ÷ (Cost of 1 t-shirt) = (How many t-shirts she can buy)
Insert your numbers: $112.04 ÷ $30.00 = 3.73466666667
Because she cant buy a fraction of a t-shirt, we ignore the decimals on the end of this number. Therefore, Staci can purchase 3 t-shirts.
PART 1.
Going westward:
Distance: 2400 miles
Rate (this is speed): (450-wind_speed) mph
Time: distance / speed = 2400 / (450-wind speed)
Going eastward:
Distance: 2400 miles
Rate (this is speed): (450+wind_speed) mph
Time: distance / speed = 2400 / (450+wind speed)
PART 2
Formula for speed:
speed = distance / time
Now we solve this for time:
time = distance / speed
11h = 2400 / (450+-wind_speed)
+- sign is put because in one case wind increases speed of plane and in other case it decreases speed.
PART 3
To solve for wind_speed we start by rearranging formula so that we have wind_speed on left side:
(450+-wind_speed) = 2400 / 11
(450+-wind_speed) = 218mph
To fly this distance in 11h speed of plane must be 218mph.
The only way to get this solution is if we substract wind speed:
450-wind_speed = 218
wind_speed = 450-218 = 232mph
