mark has 100$in his savings account. He earns 25$ a week mowing lawns. If mark puts all of his earnings from mowing lawns into a savings account, how many weeks will it take for him to have 500$?

Answer:

1100 square inches

Step-by-step explanation:

Formula: LxW

Smallest rectangles area: 5*20=100= 1 rectangle

there are 2 smal  rectangles so= 100*2=200

Medium rectangles area: 5*30=150

There are 2 so= 150*2= 300

Biggest rectangle: 30*20= 600

Total Area: 200+300+600= 1100 square inches

Answer:

  p - q = 5

Step-by-step explanation:

You have p+q = 12 and p²-q² = 60. You want the value of p-q.

The difference of squares is factored as ...

  p² -q² = (p +q)(p -q)

Substituting given values, this becomes ...

  60 = 12(p -q)

Dividing by 12 gives the difference of interest:

  5 = p -q

The amplitude is 3

for a sine graph, the amplitude is the distance up or down from the midway point. The equation to find the amplitude is (max-min) / 2.

(3 - (-3)) / 2 = 3

Answer:

y= 4x -3

Step-by-step explanation:

1) add -8x at both members

8x - 2y - 8x = 6 - 8x

-2y =  -8x + 6

2) divide both members by -2

y = 4x -3

B. circle

∵

A circle has infinite lines of symmetry.

The probability that Team A wins the best-of-five series over Team B is 17/81.

To determine the probability that Team A wins the best-of-five series against Team B, we need to consider the different possible outcomes. Team A can win the series by winning 3 games or 4 games or 5 games.

The probability of winning exactly 3 games out of 5 can be calculated using the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

where n is the total number of games (5 in this case), k is the number of games won (3 in this case), and p is the probability of winning a single game (1/3).

Using this formula, we can calculate the probability of winning 3 games, 4 games, and 5 games, and then add them together to get the overall probability of winning the series.

P(Winning series) = P(X = 3) + P(X = 4) + P(X = 5)

= C(5, 3) * \((1/3)^3\)* \((2/3)^2\)+ C(5, 4) *\((1/3)^4\) * (2/3) + C(5, 5) * \((1/3)^5\)

= (10 * 1/27 * 4/9) + (5 * 1/81 * 2/3) + (1 * 1/243)

= 40/243 + 10/243 + 1/243

= 51/243

= 17/81

Therefore, the probability that Team A wins the best-of-five series over Team B is 17/81.

The comparison between A and B is as follows:A < B.

We are given that:120 % of A is equal to 150 => (120/100)A = 150

Divide both sides by 120/100: A = 150 × 100/120 = 125

And, 105 % of B is equal to 165 => (105/100)B = 165

Divide both sides by 105/100: B = 165 × 100/105 = 157.14

Therefore, A = 125 and B = 157.14

Compare A and B:It can be seen that B is greater than A. Therefore, B > A. Hence, the comparison between A and B is as follows:A < B.

The average speed on stated speed for going and return journey is 24 miles per hour.

Average speed = total distance travelled/time taken

Let us assume the distance between store and starting point is d.

Total distance travelled = d + d

Total distance = 2d

Time while going = d/20

Time while returning = d/30

Keep the values in formula

Average speed = 2d/(d/20 + d/30)

Simplify denominator

Average speed = 2d/(30d + 20d/600)

Rearrange the values

Average speed = 2d × 600/50d

Cancel d and multiply

Average speed = 1200/50

Performing division

Average speed = 24 mph

We may deduce from the contour map that the estimates of the given functions are;

fx(2, 1) = 10

fy(2, 1) = 3

The geographic mapping used as a form of activism against prevailing power systems is known as counter-mapping.

Contour lines are described as the faint lines drawn on a map that link places of equal height above sea level. This indicates that even if you followed a contour line physically, the elevation (height of the land) would stay constant.

According to the contour map, the contour lines indicate that the coordinate (2, 1) in the x-direction has a value of 10.

Therefore;   fx(2, 1) = 10

Using the same idea, we can deduce from the attached contour map that the coordinate (2, 1) in the y-direction will have a value between 0 and 6. Therefore;

Average = (0 + 6) divided by 2 = 3

Thus;   fy(2, 1) = 3

The given statement "The this pointer is not automatically passed to static member functions of a class." is false as static member functions can be called without creating an object of the class, and the "this" pointer is used to refer to the current instance of the class. Since no instance is required for static member functions, the "this" pointer is not applicable in this case.

In object-oriented programming, a class is a blueprint for creating objects, and member functions are functions defined within a class that can be called on objects of that class.

Static member functions, also known as class methods, are special member functions that are associated with the class itself rather than any specific object or instance of the class. They are declared using the "static" keyword.

Since static member functions do not operate on specific instances of the class, they do not have access to the "this" pointer. The "this" pointer is a hidden pointer that points to the current object instance, allowing non-static member functions to access the data members and other member functions of the object. However, static member functions do not have this pointer because they are not tied to any specific object.

Static member functions can only access static members of the class, which include static variables and other static member functions. They can be called using the class name itself, without creating an instance of the class. This is because they are not associated with any particular object but rather with the class as a whole.

Uhh it's easy, did you really pay attention at ALL during the lesson. Literally don't judge on here but really!!!?

Answer:

Yes

Step-by-step explanation:

We can make one equation other to the other to solve for x-value first;

=> -4x = x - 5

=> -4x + (-x) = -5

=> -5x = -5

=> x = -5/-5

=> x = 1

Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;

=> y = x - 5

=> y = (1) - 5

=> y = -4

Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

Given is a system of inequalities, y < -x and 2x+y > 2, we need to determine solution set of the given system of inequalities,

The inequalities are,

y < -x....(i)

2x+y > 2

y < 2-2x...(ii)

To find the ordered pair, put y = -x in equation Eq(ii) and replace < by =

-x = 2 - 2x

x = 2

y = -2

Recall the binomial theorem.

\((a+b)^n = \displaystyle \sum_{k=0}^n \binom nk a^{n-k} b^k\)

1. The binomial expansion of \(\left(1+\frac x3\right)^7\) is

\(\left(1 + \dfrac x3\right)^7 = \displaystyle\sum_{k=0}^7 \binom 7k 1^{7-k} \left(\frac x3\right)^k = \sum_{k=0}^7 \binom 7k \frac{x^k}{3^k}\)

Observe that

\(k = 1 \implies \dbinom 71 \left(\dfrac x3\right)^1 = \dfrac73 x\)

\(k = 2 \implies \dbinom 72 \left(\dfrac x3\right)^2 = \dfrac73 x^2\)

When we multiply these by \(8-9x\),

• \(8\) and \(\frac73 x^2\) combine to make \(\frac{56}3 x^2\)

• \(-9x\) and \(\frac73 x\) combine to make \(-\frac{63}3 x^2 = -21x^2\)

and the sum of these terms is

\(\dfrac{56}3 x^2 - 21x^2 = \boxed{-\dfrac73 x^2}\)

2. The binomial expansion is

\(\left(2a - \dfrac b2\right)^8 = \displaystyle \sum_{k=0}^8 \binom 8k (2a)^{8-k} \left(-\frac b2\right)^k = \sum_{k=0}^8 \binom 8k 2^{8-2k} a^{8-k} b^k\)

We get the \(a^6b^2\) term when \(k=2\) :

\(k=2 \implies \dbinom 82 2^{8-2\cdot2} a^{8-2} b^2 = 28 \cdot2^4 a^6 b^2 = \boxed{448} \, a^6b^2\)
