To find the original amount, you do the amount she got correct divided by (1 minus the percentage). 

Let P = amount of problems on the test. 

P = 14 / (1 - 0.56) 
= 14/ 0.44
≈ 31.818 repeating. 

You can have part of a question (in this math, that is. Partial credit IRL exists) so we round to the nearest whole question, 32. 

The test had 32 questions.

56% = 14 questions

1% = 14 ÷ 56 = 0.25 questions

100% = 0.25 x 100 = 25 questions

Answer: 25 questions.

The Rodriguez family went to dinner at at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50;
lidiya [134]
Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
                                                                                 = 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
                                             = 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
                              = 355.95/100 dollars
                              = 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
                                                       = 172.04/100 dollars
                                                       = 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
                                           = 29.01 dollars

Solve for X and solve for Y?
Llana [10]

Answer:

x=3\sqrt 5\\

y = \sqrt {126}

Step-by-step explanation:

By geometric mean property:

x =  \sqrt{9 \times 5}  =  \sqrt{45} = 3 \sqrt{5}   \\  \\ by \: pythagoras \: theorem \\  \\  {y}^{2}  =  {9}^{2}  +  {x}^{2}  \\  \\  {y}^{2}  =  {9}^{2}  +  {(3 \sqrt{5}) }^{2}  \\  \\  {y}^{2}  = 81 + 45 \\  \\  {y}^{2}  = 126 \\  \\ y =  \sqrt{126}

If 3x+54+(65 × 32)+ 902- (43/12) =y, then what is y?
IceJOKER [234]

Answer:

We cannot solve without a value for x. The simplified form is 3x+\frac{36,389}{12} =y

Step-by-step explanation:

If the equation is 3x+54+(65)(32)+902-\frac{43}{12}=y then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

3x+54+(65)(32)+902-\frac{43}{12}=y \\3x+54+2,080+902-\frac{43}{12}=y \\3x+3,036-\frac{43}{12}=y \\3x+\frac{36,432}{12} -\frac{43}{12} =y\\3x+\frac{36,389}{12} =y
