Consider the following exam question and student solution. Determine whether the solution is correct. If it is not​ correct, write a note to the student explaining why it is wrong and give a correct solution. Exam​ question: You can buy a ​56 pound bag of flour for ​$9 or you can buy a​ 1-pound bag for .39 cents. Compare the per pound cost for the large and small bags. Student​ solution: The large bag price is 56 divided by 9=6.22 ​per​ pound, which is much more than the 39 cent per pound price of the small bag.

Answer:66

Step-by-step explanation:Eric had 100 at first minus 50 then the kite rose 16 more which equals 66

The number of yards of string left on spool is 34 yards.

Given that, Eric’s kite spool had 100 yards of string.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

At first, he let out 50 feet of string. Then, the kite rose for another 16 yards.

Now, 50+16=66 yards

So, 100-66=34 yards

Hence, the number of yards of string left on spool is 34 yards.

Using it's concept, it is found that the probability that the golf ball is green or red is of 0.55.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 6 + 5 + 9 = 20 balls, of which 11 are green or red, hence the probability is given by:

p = 11/20 = 0.55.

Answer:

  -19.3%

Step-by-step explanation:

The percentage change in a value is computed from ...

  percent change = ((new value) -(old value))/(old value) × 100%

  = (2694 -3339)/3339 × 100% = -645/3339 × 100% ≈ -19.3%

The decrease in 50 years is about 19.3%.

Answer:

Answer:

Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.

Step-by-step explanation:

This is the sample response.

The graph of the function h(x) = 5x² + 12 is more compact than the graph of function f(x) = x² and both the graphs represent parabolic curve along y axis.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The graph of the two functions is attached with the answer below. For the first graph, we will get the parabola whose vertex lies on the origin.

For the function h(x) = 5x² + 12 the graph will again parabolic having its vertex at ( 0,12) and the parabola is more compact than the parabola of the function F(x) = x².

Therefore the graph of the function h(x) = 5x² + 12 is more compact than the graph of function f(x) = x² and both the graphs represent parabolic curve along y axis.

Answer:

c. 625.91

Step-by-step explanation:

took the quiz an got 100%

The starting balance is $625.91 if the card has a billing cycle of 30 days and an APR of 14.75%. Option (C) is correct.

The full name of APR is the annual percentage rate. It is defined as the percentage rate applied on the borrowing money in the form of interest, but APR has applied annually.

We have:

His card has a billing cycle of 30 days and an APR of 14.75%.

Here the list data is not mentioned, clearly. Transactions with the amount.

As we know, the APR is the annual percentage rate, which is 14.75%.

Monthly percentage rate = 14.75/12 = 1.22%

But we can calculate the new balance with the formula:

Previous Balance + Finance Charge + New Purchases - (Payments + Credits) = New Balance

Thus, the starting balance is $625.91 if the card has a billing cycle of 30 days and an APR of 14.75%. Option (C) is correct.

Answer: x=2

Step-by-step explanation:

We can see that ∠RTU and ∠STR make up ∠STU. Therefore, we add them together and set it equal to 114°.

24x+34x-2=114                [combine like terms]

58x-2=114                         [add both sides by 2]

58x=116                            [divide both sides by 58]

x=2

Answer: y=7x

Step-by-step explanation:

To find the line that is parallel to the given line, we know that the slope will stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST stay the same. All we have to do is plug in the given point to find the y-intercept.

y=7x+b

0=7(0)+b          [multiply]

b=0

Now, we know the equation is y=7x+0 or y=7x.

The inequality for the given statement is 10x>300.

We need to find what number is 10 times greater than 300.

In Mathematics, equations are not always about being balanced on both sides with an 'equal to' symbol. Sometimes it can be about a 'not an equal to' relationship like something is greater than the other or less than. In mathematics, inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.

Let the unknown number be x.

Now, 10 times the number=10x

The number is 10 times greater than the 300.

That is, 10x>300

Therefore, the inequality for the given statement is 10x>300.
