The surface area and volume of cement block is  1336 in² and 880 in³

To find the total surface area of a cuboid, add the areas of all six faces. Suppose l, b and h be the length, breadth and height of a cuboid, then the total surface area will be 2(lb + bh + hl). The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

Surface area of given cement block is = 10×8×2+20×10×2+(20×8 - 6×4×3)×2 + 4×10×2×3 +6×10×2×3

= 160 + 400 + 176 + 240 + 360

= 1336 in²

Volume of cement block is 20 × 8× 10 - 3×6×4×10

= 1600 - 720

= 880 in³

Hence, the surface area and volume of cement block is  1336 in² and 880 in³

According to the given information, 10 grey wolf pups will survive to adulthood.

What is a fraction?

A fraction is a mathematical expression that represents a part of a whole or a division of one quantity by another.

Yellowstone National Park is home to a variety of wildlife, including the grey wolf. A survey conducted in the park recorded the birth of 25 grey wolf pups. However, it is estimated that only 2/5 of these pups will survive to adulthood.

To estimate the number of grey wolf pups that will survive to adulthood, we can use a simple mathematical formula. We multiply the total number of grey wolf pups by the estimated survival rate:

Survivors = (2/5) x 25

Therefore, we can estimate that 10 grey wolf pups will survive to adulthood.

Answer: X = -2/5

Step-by-step explanation:

Answer:

This has already been answered correctly (x = -2/5), but I'll add the steps required to arrive at that conclusion.

Step-by-step explanation:

Solving 2(5x+3)=2 requires that we use the order of operations, or PEDMAS, in going through the steps.  PEDMAS is the acronym for Parentheses, Exponents, Division, Multiplication, Addition and Subtraction.  These are the order in which math operations should be done when solving equations.  This provides the "rules of the road" when interpreting how equations were meant to be read.

2(5x+3)=2    

1.  Parentheses:  First, we should complete whatever is inside a set of parentheses, in this case (5x+3).  There is nothing we can do with (5x+3) so go to the next step.

2. Exponents:  none here, so continue

3.  Division:  none here, so continue

4.  Multiplication:  We can do the term 2(5x+3) by multiplying the 2 times each of the values within the parentheses.

        2(5x+3) = 10x + 6

We now have:

         10x + 6 = 2

5.  Addition/Subtraction:  Subtract 6 from both sides:

         10x + 6 - 6 = 2 - 6

         10x = - 4

We've gone through PEDMAS once, so start over again since we are still looking for the value of x.

The only operation left is to divide both sides by 10:

     10x = -4

      10x/10 = -4/10

   x= - 4/10 or -2/5

In general, PEDMAS works quite well.  It defines how to interpret the manner in which equations are written.  If there is any remaining ambiguity, always work from left to right.  Solve the portion on the left first, then move right.  

Also, it is always good, and edifying, to try the solution to see if the equation works for that solution.  We can ask "Does a value of x=-(2/5)  give the answer of "2" when used in 2(5x+3)?

   2(5x+3)        

   2(5*(-2/5) + 3) =  2?                 for x = -(2/5)

    2(5*(-2/5) + 3) =  2?  

Use PEDMAS:

     2(5*(-0.4) + 3) =  2?

     2(-2 + 3) = 2?

      2(1)  = 2?                     YES, -(2/5) is correct

Answer:

To compare the balances of the two loans at the time of repayment, we need to calculate the future value of the loan amount for each loan option after 12 months of compounding.

For the Unsubsidized Stafford Loan:

Principal (P) = $9,529

Annual interest rate (r) = 5.95%

Compounding period (n) = 12 (monthly compounding)

Time period (t) = 1 year

Using the formula for future value of a loan (FV), we get:

The formula is:

FV = P * (1 + r/n)^(nt) = $9,529 * (1 + 0.0595/12)^(121) = $10,087.14

For the PLUS Loan:

Principal (P) = $10,172.23

Annual interest rate (r) = 6.55%

Compounding period (n) = 12 (monthly compounding)

Time period (t) = 1 year

Using the same formula, we get:

FV = P * (1 + r/n)^(nt) = $10,172.23 * (1 + 0.0655/12)^(121) = $10,774.71

Therefore, the Unsubsidized Stafford Loan will have a lower balance at the time of repayment, by $687.57 ($10,087.14 - $10,774.71).

The required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.

These are the equation that contains trigonometric operators such as sin, cos.. etc. In algebraic operation.

Let,

= \(tan(\pi /12) = tan((3-2)\pi /12)\)
\(= tan[(3\pi -2\pi )/12]\\=tan(3\pi /2-2\pi /12)\\=tan(\pi /4-\pi /6)\\=\frac{tan(\pi/4)-tan(\pi/6)}{1+tan(\pi/4)tan(\pi/6)}\)
= \(\frac{1-1/\sqrt{3} }{1+1*1/\sqrt{3} } \\\)
\(=\frac{(\sqrt{3}-1)/\sqrt{3}}{(\sqrt{3}+1))/\sqrt{3}}\)
\(=\frac{(\sqrt{3}-1)}{(\sqrt{3}+1)}\\=\frac{(\sqrt{3}-1)(\sqrt{3}+1)}{(\sqrt{3}+1)(\sqrt{3}+1)}\\=\frac{(3-2\sqrt{3}+1)}{(3-1)}\\\\=\frac{(4-2\sqrt{3})}{(2)}\\={(2-\sqrt{3})}\\\)


Thus, the required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.

Answer:

Step-by-step explanation:

Let's start by adding the fractions to find out how many flags are either purple or orange. We can write the fractions with a common denominator of 10:

1/10 (purple flags) + 3/10 (orange flags) = 4/10

Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor of 2, we get:

4/10 = 2/5

Therefore, 2/5 of the flags in Kendrick's Flag Shop are either purple or orange.

To explain this further, we can say that out of every 10 flags in the shop, 1 is purple and 3 are orange. However, some of these flags may be both purple and orange, so we can't simply add 1/10 and 3/10 to get the total fraction of flags that are either purple or orange. Instead, we need to find the total fraction of flags that are purple or orange by adding the fractions and then simplifying to get the answer in its lowest terms. In this case, the answer is 2/5.

The function is increasing over the interval (-3,-1).

A table with x and f(x) values are given as:

x         f(x)

-6         34

-5          3

-4        -10

-3         -11

-2         -6

-1           -1

0           -2

1            -15

We have to check whether this function is increasing or not in the intervals  (–6, –3), (–3, –1), (–3, 0), (–6, –5).

A function is said to be increasing over an interval (x, y), if for x < y, it follows that f(x) < f(y).

Consider the intervals one-by-one.

For (-6, -3), we have the function values in between which are  34 > 3 > -10 > -11. So in this interval the function is not increasing but decreasing over the x-values in (-6, -3).

For (-3, -1), the corresponding function values are -11 < -6 < -1. Here the function values are increasing over the x-values in the interval (-3, -1).

For (-3,0), the corresponding function values are -11 < -6 < -1 >-2. Since we got -1 > -2 in the interval (-3,0), the function is not increasing here also.

For (-6,-5), the corresponding function values are 34 > 3. So the function is not increasing but decreasing.

Set up a right triangle to reflect the tangent ratio. Tangent is equal to the side opposite the reference angle over the side adjacent to the reference angle. If tangent is 4/3, then the side opposite the reference angle is 4 in length and the side adjacent is 3 in length. The reference angle, just for clarification, is the base angle that is not the right angle. So we have a right triangle with a height of 4 and a base of 3. We need the sin ratio from that. The sin ratio by definition is the side opposite the reference angle over the hypotenuse. But we don't have the hypotenuse. We have to solve for it using Pythagorean's Theorem.

\(h^2=4^2+3^2\) and

\(h^2=16+9\) and

\(h^2=25\) so

h = 5. Now we find the sin ratio to be 4/5 (the side opposite the reference angle over the hypotenuse).

The probability that Dawn selects a matching pair of socks is approximately 0.267 or 26.7%.

To calculate the probability that Dawn selects a matching pair of socks, we can use the concept of combinations. In this case, we have 3 white, 2 red, and 1 green sock, totaling 6 socks in the drawer. We are interested in finding the probability of selecting a matching pair, which can be either white or red since there is only one green sock.

First, let's find the total possible combinations of selecting two socks from six. This is represented by the formula C(n, k) = n! / (k!(n-k)!), where n is the total number of items and k is the number of items we want to select. In this case, n = 6 and k = 2.

C(6, 2) = 6! / (2!(6-2)!) = 15 total combinations.

Now, let's find the combinations of selecting matching pairs. There are C(3, 2) = 3 combinations for selecting two white socks and C(2, 1) = 1 combination for selecting two red socks. The green sock does not have a matching pair, so it is not considered.

Therefore, the total matching combinations are 3 (white) + 1 (red) = 4.

Finally, to find the probability, we can divide the matching combinations by the total combinations:

Probability = Matching combinations / Total combinations = 4/15 ≈ 0.267.
