How do i simply the answer???

Answer:

159

Step-by-step explanation:

So first you work on the (3 + 5) which is 8 but don't forget the ^2 so 8^2 is 64. Then you work on your next term which is 10^2 which is 100. So now our equation is 100 + 64 -5 and you can solve this by going left to right. So 100 + 64 is 164 then - 5 is 159.

In the equation, the ordered pair for x = 5 is (5, 5.5), the ordered pair for x = 10 is (10, 8), the ordered pair for x = 20 is (20, 13).

A linear equation has the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. The line's rate of change, or how steeply it rises or descends as we go down the x-axis, is indicated by the slope. The line's intersection with the y-axis, or the value of y when x is equal to 0, is represented by the y-intercept.

The given equation is:

y=0.50x + 3

Substituting the different values of x we find the required ordered pair as follows:

When x = 5:

y = 0.50(5) + 3 = 5/2 + 6/2 = 11/2 = 5.5

When x = 10:

y = 0.50(10) + 3 = 5 + 3 = 8

When x = 20:

y = 0.50(20) + 3 = 10 + 3 = 13

Therefore, the ordered pair for x = 5 is (5, 5.5), the ordered pair for x = 10 is (10, 8), the ordered pair for x = 20 is (20, 13).

Answer:

Let's start by finding how much money Mary has left after buying the gift cards:

$250 - $130 = $120

Now, to find the greatest number of candy bars Mary can buy, we need to divide the amount of money she has left by the cost of each candy bar:

$120 ÷ $1.50 = 80

So Mary can buy up to 80 candy bars with the rest of her money.

We can check which inequality represents this situation by plugging in the numbers:

130 + 1.50x ≤ 250

where x represents the number of candy bars Mary buys.

If we subtract 130 from both sides, we get:

1.50x ≤ 120

Finally, if we divide both sides by 1.50, we get:

x ≤ 80

This matches our answer, so the correct inequality is:

D. 130 +1.50x ≤ 250

Answer:

D. 130 +1.50x ≤ 250

How is optimization employed in mathematics?

The process of selecting the optimal answer from a range of alternatives is known as optimization. In mathematics, optimization is employed to determine a function's maximum or least value. Typically, an optimization issue entails the optimization of a function under a set of restrictions.

Let's assume that the length of the left border is x feet.

The length of the lower border is y feet.

From the given situation the equation is:

8x + 2y = 320

To maximize the area of the garden, we maximize the product xy.

2y = 320 - 8x

y = 160 - 4x

Substituting this expression for y into the expression for the area, we get:

A = xy = x(160 - 4x) = 160x - 4x²

To find the value of x that maximizes the area, we can take the derivative of A with respect to x and set it equal to zero:

dA/dx = 160 - 8x = 0

x = 20

Substituting x = 20 back into the expression for y, we get:

y = 160 - 4x = 80

Therefore, the dimensions of the garden are 20 feet by 80 feet, and the area enclosed is: A = xy = (20)(80) = 1600 feet².

As a result, the total area of these four triangular regions, a2 - b2, represents the disparity between the two squares' surface areas.

A triangle is a two-dimensional geometric shape with three straight edges and three angles. It is one of the fundamental geometric forms and can be categorised in various ways based on the sides and angles it has. Triangles are typically categorised according to their edges as follows: Equilateral triangles have three identical sides and three equal angles, each measuring 60 degrees. A triangle with an isosceles triangle has two edges that are equal and two angles that are equal.

A triangle called a scalene triangle lacks equal edges and angles.

given

The four triangular areas outside the smaller square but inside the bigger square are the regions that stand for a2 and b2.

Consider the size of the large rectangle, which is a2, to understand why this is the case. Consider the smaller square's size, which is b2.

These two areas vary by (a2) - (b2), which we can also write as:

(a + b)(a - b) (a - b)

According to this formula, the difference between the two squares' areas is equivalent to the product of their side lengths' sum and differences.

We can write the sum and difference of their side lengths as (a + b) and (a - b), respectively, because the big square's side length is a and the smaller square's side length is b.

The area of the four triangular areas outside the smaller square but inside the larger square is represented by the product (a + b)(a - b).

Answer:

The center of the circle is at the point (2, -3), and its radius is 4 units

Step-by-step explanation:

The equation of the circle in standard form can be obtained by completing the square for both x and y terms as follows:

7x^2 - 28x + 7y^2 + 42y - 35 = 0

7(x^2 - 4x) + 7(y^2 + 6y) = 35

7(x^2 - 4x + 4 - 4) + 7(y^2 + 6y + 9 - 9) = 35

7[(x - 2)^2 - 4] + 7[(y + 3)^2 - 9] = 35

7(x - 2)^2 + 7(y + 3)^2 - 112 = 0

7(x - 2)^2 + 7(y + 3)^2 = 112

Dividing by 112 on both sides, we get:

(x - 2)^2 + (y + 3)^2 / 16 = 1

The probability is approximately 0.129

To calculate the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag, we need to use the binomial probability formula:

P(X >= 48) = 1 - P(X < 48)

Where

To calculate P(X < 48), we need to use the binomial probability formula:

P(X = x) = (nCx) * p^x * q^(n-x)

Where

nCx is the binomial coefficient, which can be calculated using the formula:

nCx = n! / (x! * (n-x)!)

where ! denotes the factorial function.

We can use a cumulative binomial distribution table or a binomial calculator to find the probability of getting less than 48 orange Stattles in a 14 ounce bag. For example, using an online calculator, we find that:

P(X < 48) = 0.871

Therefore, the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag is:

P(X >= 48) = 1 - P(X < 48) = 1 - 0.871 = 0.129

Algebraic expression can be defined as combination of variables and constants.

Let's assume that Timothy has x dollars when he enters the first store.

According to the problem, he spends 1 dollar more than half of what he has.

So, the amount he spends in the first store is:

1/2 * x + 1

After spending this amount, he will have:

x - (1/2 * x + 1) = 1/2 * x - 1

dollars left.

He then goes to the second store and spends 1 dollar more than half of what he has left, which is:

1/2 * (1/2 * x - 1) + 1 = 1/4 * x + 1/2

After spending this amount, he will have:

1/2 * x - 1 - (1/4 * x + 1/2) = 1/4 * x - 3/2

dollars left.

He repeats this process for each of the five stores.

Therefore, the amount of money Timothy has left after visiting all five stores is:

1/4 * x - 3/2 - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) = -5/4 * x - 5

Since he has spent all his money, the amount of money he has left must be 0:

-5/4 * x - 5 = 0

Answer:

737 cooks are required to prepare a meal for 737 people in 5 hours

Step-by-step explanation:

According to the given information, 10 cooks can prepare a meal for 536 people working for 8 hours each.

Let's calculate the total work done by the 10 cooks in 8 hours.

Total work done = Number of cooks * Hours worked

Total work done = 10 * 8 = 80

Now, let's calculate the work done by one cook in one hour.

Work done by one cook in one hour = Total work done / (Number of cooks * Hours worked)

Work done by one cook in one hour = 80 / (10 * 8) = 1

Therefore, one cook can prepare food for 1 person in 1 hour.

Now, let's calculate the number of cooks required to prepare a meal for 737 people in 5 hours.

Total work required = Number of people * Hours required

Total work required = 737 * 5 = 3685

Number of cooks required = Total work required / (Hours worked * Work done by one cook)

Number of cooks required = 3685 / (5 * 1) = 737

Therefore, 737 cooks are required to prepare a meal for 737 people in 5 hours.

The highest height of the ball, to the closest foot, is stated to be around 88 feet.

Velocity may be referred to as the speed when something moves toward a particular location. as the rate of a car driving northwest on a highway or the pace at which a rocket takes off.

The function h(t) = −16t² + v0t + h0 models the vertical motion of the ball, where t is time in seconds, v0 is the initial velocity in feet per second, and h0 is the initial height in feet.

In this case, the beginning height is 4 feet, and the velocity of the fluid equals 75 feet per second. As a result, the following outlines the function h(t) which it simulates the ball's vertical motion:

h(t) = -16t² + 75t + 4

The point of the concave function h must be located in order to determine the ball's peak (t) = -16t² + 75t + 4.

The t-coordinate of the vertex is given by t = -b/2a, where a = -16 and b = 75. Substituting these values, we get:

t = -75 / (2 x (-16)) = 2.34375

We enter this t quantity into the procedure h(t) to get the maximum height:

h(2.34375) = -16(2.34375)² + 75(2.34375) + 4 = 87.74
