Answer:

[tex]180^{\circ}[/tex]

Step-by-step explanation:

Given that,

Total pies that sold = 700

Pumpkin pies = 350

We need to represent the degrees in the circle. It can be calculated as follows :

[tex]x=\dfrac{350}{700}\times 360\\\\x=180^{\circ}[/tex]

So, the pumpkin pies are represented by [tex]180^{\circ}[/tex].

Inequalities help us to compare two unequal expressions.The compound inequality that shows the range of numbers that Dewayne might be thinking of is 8<(5n-7)<13.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given clue by Dewayne can be written in the form of inequality as shown below. Therefore, we can write,

Hence, the compound inequality that shows the range of numbers that Dewayne might be thinking of is 8<(5n-7)<13.

Answer:

[tex]Q(t) = 50e^{-0.0527t}[/tex]

Step-by-step explanation:

A certain radioactive material is known to decay at a rate proportional to the amount present.

This means that the situation can be described by the following differential equation:

[tex]\frac{dQ}{dt} = -rQ[/tex]

In which r is the decay rate.

Solving the differential equation by separation of variables, we have that:

[tex]\frac{dQ}{Q} = -r dt[/tex]

Integrating both sides:

[tex]\ln{Q} = -rt + K[/tex]

In which K is the integrative constant.

Applying the exponential to both sides, to remove the ln, we get:

[tex]Q(t) = Ke^{-rt}[/tex]

In which K is the initial amount present.

Initially there is 50 mg/L

This means that [tex]K = 50[/tex].

After 2 hours it is observed that the material has lost 10 percent of its original concentration

This means that [tex]Q(2) = 0.9K[/tex]. So

[tex]0.9K = Ke^{-2r}[/tex]

[tex]e^{-2r} = 0.9[/tex]

[tex]\ln{e^{-2r}} = \ln{0.9}[/tex]

[tex]-2r = \ln{0.9}[/tex]

[tex]r = -\frac{\ln{0.9}}{2}[/tex]

[tex]r = 0.0527[/tex]

So

[tex]Q(t) = Ke^{-rt}[/tex]

[tex]Q(t) = 50e^{-0.0527t}[/tex]

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

10/32 - > 5/16

The two consecutive whole numbers that 54 lies between are 27 and 28, since 54 is greater than 27 and less than 28.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

To find two consecutive whole numbers that 54 lies between, we can start by dividing 54 by 2 and rounding down to the nearest whole number since we want two consecutive numbers that are less than and greater than 54:

54 ÷ 2 = 27

So the two consecutive whole numbers that 54 lies between are 27 and 28, since 54 is greater than 27 and less than 28.

Step-by-step explanation:

To evaluate the expression if a = 4, b = 3, and c = 2, substitute those values for the variables and solve. So, substitute 4 for a, 3 for b, and 2 for c, then simplify by the correct order of operations, PEMDAS:

[tex]ab - bc \\(4)(3)-(3)(2)\\= 12 - 6 \\= 6[/tex]

Therefore, the answer is 6.

To find a percentage, you will need to divide both numbers by each other. In this case, it would look similar to this:

[tex]\text{23 / 25 = ???}[/tex]

Once you divide the two numbers, you should end up with a result of [tex]0.92[/tex]

Now, we are going to move the decimal two spaces to the right to end up with the result:

[tex]\text{092.}[/tex]

Now, we are going to remove the [tex]0[/tex] as it is no longer required. Next, add a percentage symbol to the last number, and remove the decimal from the number.

Now, you should end up with something like this:

Answer:

$52.03

Step-by-step explanation:

1. Approach

To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.

2. Find the tax

As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.

a. convert percent to decimal

8.4 / 100 = 0.084

b. multiply the decimal by the amount spent

48 * 0.084 = 4.032

The amount spent on sales tax is, $4.032

3. Find the total amount spent

Now all one has to do is add the amount spent in tax by the amount spent on the purchase.

48 + 4.032 = 52.032

Since money is only spent rounded to the second decimal point, one has to round the number;

Step-by-step explanation:

Answer:

1.81?

Step-by-step explanation:

Answer: True.

Step-by-step explanation:

Here we have the number:

26,59,360

To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)

For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)

Then the place value of the 5 in that number will be 10^4

this is equal to:

10^4 = (10)*(10)*(10)*(10) = 10,000

This means that the place value of the 5 is then thousand.
