Mary is making a birthday cake to surprise her mom. She needs 3 1/2 cups of flour, but she only has 1/3 cup. How much more flour does she need?

Answers

Answer:

3 1/6 cups more

Step-by-step explanation:

Answer:

3 1/2 = 7/2 (write as a mixed number)

7/2 - 1/3 = ?( you need more flour, so subtract what you have from what you need. to subtract you need to find the least common denominator)

21/6 - 2/6

19/6 cups of flour is what you need.

or 3 1/6 cup if it needs to be converted back into a mixed fraction

Find the Error A student solved the equation and determined that the solution was –2. Choose the response that shows her error and corrects it.




Multiple choice question.

A)
There is no error, her answer is correct.


B)
The initial equation simplifies to 3x = 0, which means that x = 0.


C)
The equation –2 = –2 is always true, so no value of x will make the equation true. The correct solution of the equation is that there is no solution.


D)
The equation –2 = –2 is always true, so every value of x will make the equation true. The correct solution of the equation is infinitely many solutions.

Answers

The equation –2 = –2 is always true, so no value of x will make the equation true. The correct solution of the equation is that there is no solution.

What is equation?

In mathematics, an equation is a statement that shows the equality between two expressions. It contains an equals sign (=) that separates the two expressions. The expressions on both sides of the equals sign can be numbers, variables, or functions. The equation represents a relationship between the expressions that must hold true for all values of the variables involved. Solving an equation means finding the values of the variables that satisfy the equation. Equations are used in various fields, such as physics, engineering, economics, and many others, to model and solve real-world problems.

Here,

The error made by the student is assuming that -2 is the solution to the equation without actually solving it. The equation -2 = -2 is always true, which means that the equation is an identity and has no solution. So, the correct solution of the equation is that there is no solution.

Shelley is visiting from London and uses her ATM card to withdraw $200 at local bank B. If local bank B charges $4 for ATM fees per foreign transaction plus 3% of the withdrawal, how much would she own in fees for what transaction? Round to the nearest dollar amount, such as: $6


$5

$4

$10

$7

Answers

Answer:

Transaction Fee =  $10

Step-by-step explanation:

Transaction fee = $4 for ATM fees per foreign transaction + 3% of the withdrawal

Withdrawal = $200

3% of the withdrawal = 3/100    *   $200 = $6

Transaction Fee =  $4  +  $6 =  $10

Answer:

y=93°, z=79°

Step-by-step explanation:

Lines and Angles

There are properties of lines and angles that will help us to find the required values.

The vertex at the bottom left side of the quadrilateral has two angles that were formed when two lines crossed. Those are called linear angles, and they always add up to 180°.

This means that z is the angle needed to complete 180°, that is:

z = 180° - 101° = 79°

Now the quadrilateral must have the sum of its internal angles equal to 360°. We have three of them that sum: 100°+88°+79°=267°.

This means y is the angle needed to complete 360°, or:

y = 360° - 267° = 93°

Answer: y=93°, z=79°
