yolanda measures the depth of the water in a reservoir. In one week the depth changes from 2,366.74ft to 2,354.63.ft. what rational number represents the average change in the depth each day? Show your work.

Answers

Answer 1

Answer:

Step-by-step explanation:

To find the average change in depth each day, we need to divide the total change in depth by the number of days.

Total change in depth = 2,366.74 - 2,354.63 = 12.11 ft

Number of days = 7

Average change in depth each day = Total change in depth / Number of days

= 12.11 / 7

= 1.73 (rounded to two decimal places)

Therefore, the rational number that represents the average change in depth each day is 1.73 ft per day.

(0.5x1.2)+(0.4x1.3)+(0.4x1.2)+(0.5x0.4)

Evaluate (whith steps) -3 - 5 (8 + 4) + 16 - 32

Answers

Answer:

Using the order of operations (PEMDAS), we evaluate the expression as follows:

First, we perform the operations inside the parentheses: 8 + 4 = 12.

Next, we multiply 5 by 12: 5(12) = 60.

Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.

Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.

The answer is -79 ( I think )

What is $400 at 3% for 5 years?

A. Find interest earned
B. Find the balance of the account

Answers

The interest earned is $60 and the balance of the account is $460. The interest and the balance of the account will be both calculated with their given formulas.

An expense or payment for using borrowed money is interest; it is occasionally stated as a percentage of the principal borrowed. It could also be applied to the returns on investments or savings. Interest is the cost that a borrower typically reimburses a lender for the use of their funds.

A. We must use the formula-

Interest = Principal x Rate x Time, to calculate the interest earned.

Here, Interest = $400 divided by 0.03 and multiplied by 5.

Earned interest is $60.

B. We must utilize the formula-

Balance = Principal + Interest, to determine the account's balance.

Balance = $400 + computed interest in this instance.

Balance: $400 + $60.

The account's balance is $460.

Answer:

Part A:

6 feet

Part B:

Around 9.17 feet

Part C:

Around 3 feet

Step-by-step explanation:

Part A:

The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).

Part B:

Using the same method, but with different measurements:

(a^2 + b^2 = c^2)

(16 + b^2 = 100)

(b^2 = 84)

(b = 9.17)

Part C:

The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)

PART A uses Pythagoras. Because you are finding the short side you do 8 squared and 10 squared (100 and 64) and subtract them to get 36. You then do the square root of 36 to get 6 which is the answer!

Answers

Answer:

Step-by-step explanation:

y divided by  6x6=3x6

1. multiply first

 a) 6x6 = 36

  b) 3x6=18

  c) y/6 times 6 =3 x6 .....make it a fraction    Y over 6  times 6 over 1

  d)  y/6 times 6/1----cross off the two 6's

Now:  y=3x6

          y=18

6 times 6 = 36 and 6 times 3 = 18

36 = 18

So, 18 divided by y = 36

so, 18 times 36 = 648

Hence, y is divided by 648 to get 6 x 6

For an equation of the form ax^2 + bx+ c = 0, where the graph crosses the y-axis once and does not intersect the x-axis. Describe the solution(s) of the equation.
(picture)

Answers

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved

Write the following in slope intercept form:

Answers

Answer:

The equation y + 2 = 3/4x can be written in slope-intercept form by isolating the y-term and rearranging the equation. The slope-intercept form of the equation is y = 3/4x - 2

Answer:

y = 3/4x - 2

Step-by-step explanation:

The slope intercept formula y = mx + b

so y + 2 = 3/4x

=> y + 2 -2 = 3/4x - 2

=> y = 3/4x - 2

Answer:

M = 2

Step-by-step explanation:

What does it mean to have something be equal (Equivalent)?

Equivalence means to be same, whether it be value, temperature, size, etc.

If equivalence means to be the same, we can use this equation to figure out what M is equal to.

40.3 ÷ 12.4 = 3.25

So, in order to solve for M, we need to divide 6.5 by 3.25.

6.5 ÷ 3.25 = 2

Therefore, M = 2.

Answers

Answer:113.7

Step-by-step explanation:

Answer:

113.7

Step-by-step explanation:

To calculate 20% of 568.50, you can convert 20% to a decimal by dividing it by 100.

20% ÷ 100 = 0.20

Then, you can multiply the decimal by the original value to find the answer:

0.20 x 568.50 = 113.70

Therefore, 20% of 568.50 is 113.70.

Part I: Making the Race


Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.


1. How long should the race be so that Henri will win in a close race?

2. Describe or show your strategy on how you came up with your answer for #1.

Answers

74 meters

Step-by-step explanation:

The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.

2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

For example, investments in R&D labs (managerial actions) are one mechanism that links the resource (engineers) with the firm capability (product innovation). This activity is important because when multiple resources and capabilities are aligned on a single goal, the firm may have a core competency. For instance, Canon's ability in optics originates not just in the capability of its design engineers, but also in its precision in manufacturing. When a firm's core competency is at the heart of the product itsells, that product can be considered a core product. In the case of Canon, optics are at the heart of such products as cameras, camcorders, scanners, and projectors.

Over time, Honda has maintained as its core ability a dedication to the engineering and ongoing Innovation of these small, reliable, and powerful internal combustion engines. While Honda invested much in developing and maintaining this competency. In 1960. Its management made an important decision that later became central to the creativity and productivity of its engineers and designers.
