Answer:

According to the recipe, the ratio of flour to water is 4:0.5 or 8:1 (since 1/2 can be simplified to 0.5).

To determine how much water is needed for 5 cups of flour, we can use this ratio:

8:1 = 5:x

where x represents the amount of water needed.

To solve for x, we can cross-multiply:

8x = 5 * 1

8x = 5

x = 5/8

Therefore, you will need 5/8 cup of water for 5 cups of flour, using the given recipe.

Step-by-step explanation:

The functions are equal in option A, and aren't equal in B (try input x =1 and y = -1) and in C (try input x = 0 and y = 0).

The first one is:

(a). f: Z → Z, where f(x) = x^2.

g: Z → Z, where g(x) = |x|^2.

Yes, these functions are equal, this happens because both outcomes will always be positive, indifeterent of the absolute value part.

b)   f: Z × Z → Z, where f(x,y) = |x + y|.

g: Z × Z → Z, where g(x,y) = |x| +| y|.

These are different, if x = 1 and y = -1

f(1, - 1) = |1 - 1| = 0

g(1, -1) = |1| + |-1| = 2

c) B = {0, 1}

f: B × B → B × B, where f(x,y) = (1-y, 1-x)

g: B × B → B × B, where g(x,y) = (x,y)

This is clearly false, when x and y are 0 and 0 we have:

f(0, 0) = (1 - 0, 1 - 0) = (1, 1)

While g gives:

g(0, 0) = (0, 0)

These functions are different.

Answer:

The simplified expression is -13/12.  (are you sure you don't have a typo somewhere), double checked.

Step-by-step explanation:

First, let's simplify the expression inside the absolute value bars:

5/6 - 17/12 = 10/12 - 17/12 = -7/12

Next, we can simplify the expression outside the absolute value bars:

| -7/12 | - | 5/3 |

= 7/12 - 5/3 (since the absolute value of -7/12 is 7/12)

= 7/12 - 20/12

= -13/12

The simplified expression is -13/12.

_______________________

Simplify the following:

abs(5/6 - 17/12) - abs(5/3)

Put 5/6 - 17/12 over the common denominator 12. 5/6 - 17/12 = (2×5)/12 - 17/12:

abs(((2×5)/12 - 17/12)) - abs(5/3)

2×5 = 10:

abs(10/12 - 17/12) - abs(5/3)

10/12 - 17/12 = (10 - 17)/12:

abs(((10 - 17)/12)) - abs(5/3)

10 - 17 = -7:

abs((-7)/12) - abs(5/3)

Since 5/3 is a non-negative constant, abs(5/3) = 5/3:

abs(-7/12) - 5/3

Since -7/12 is a negative constant, abs(-7/12) = 7/12:

7/12 - 5/3

Put 7/12 - 5/3 over the common denominator 12. 7/12 - 5/3 = 7/12 + (4 (-5))/12:

7/12 - (5×4)/12

4 (-5) = -20:

7/12 + (-20)/12

The experimental probability of rolling a number less than or equal to 4 is 0.7.

The likelihood that an event (A) will occur given the occurrence of another event (B) is known as conditional probability. P(A|B), which stands for "the probability of A given B," is used to express it. You must first determine P(A and B) by multiplying the odds of A and B happening together. Next, you may compute P(A|B). The conditional probability of A given B is then obtained by dividing the result by P(B).

Several situations in everyday life, including medical diagnosis, industrial quality control, and risk assessment in insurance, call for the usage of conditional probability.

Given that, the trial was run 10 times.

Thus,

P(B) = (number of times B occurred) / (total number of trials)

Answer:

the dimensions of the corral that minimize the cost of the fencing are approximately 17.91 meters by 6.54 meters.

Step-by-step explanation:

Let the length of the corral be x, and the width be y. We know that the area of the corral is 117, so:

xy = 117

We also know that the corral is divided by a fence into two sections. Let the length of one section be L, and the width be y. Then, the length of the other section will be x - L, and the width will still be y. The total fencing cost will be:

10(2x + 2y) + 6(L + 2y)

Simplifying this expression, we get:

20x + 32y + 6L

Using the area equation, we can rewrite this as:

20x + 32(117/x) + 6L

To minimize the cost, we need to take the derivative of this expression with respect to L, and set it equal to zero:

d/dL [20x + 32(117/x) + 6L] = 6 = 0

Solving for L, we get:

L = x/2

Therefore, the two sections of the corral will have equal length. Substituting this value of L into the expression for total fencing cost, we get:

20x + 32y + 3x

Simplifying this, we get:

23x + 32y

Using the area equation to substitute for y, we get:

23x + 32(117/x)

Taking the derivative of this expression with respect to x, and setting it equal to zero, we get:

23 - 3744/x^2 = 0

Solving for x, we get:

x = sqrt(3744/23) ≈ 17.91

Substituting this value of x into the area equation, we get:

y = 117/x ≈ 6.54

Therefore, the dimensions of the corral that minimize the cost of the fencing are approximately 17.91 meters by 6.54 meters.

The dimensions of the rectangular field that maximize the enclosed area are 150 feet by 75 feet.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

Let's call the length of the rectangle "l" and the width "w".

We can write two equations based on the given information -

Perimeter equation: 2l + 4w = 600 (since there are two sets of parallel sides, we have to add an extra "w" to the perimeter equation)

Area equation: A = 3lw (since the field is divided into 3 equal parts)

We want to maximize the enclosed area, which means we want to find the values of "l" and "w" that make the area as large as possible.

We can use the perimeter equation to solve for one of the variables in terms of the other -

2l + 4w = 600

2l = 600 - 4w

l = 300 - 2w

Now we can substitute this expression for "l" into the area equation -

A = 3lw

A = 3(300 - 2w)w

A = 900w - 6w²

To find the maximum area, we can take the derivative of this equation with respect to "w" and set it equal to zero -

dA/dw = 900 - 12w = 0

12w = 900

w = 75

So the width of each of the smaller rectangular plots is 75 feet.

We can use the perimeter equation to find the length -

2l + 4w = 600

2l + 4(75) = 600

2l = 300

l = 150

Therefore, the dimensions value are obtained as 150 feet by 75 feet.

Let the age of the son be $s$ and the age of the father be $f$. From the first equation, we have $2s + f = 56$, and from the second equation, we have $f + 2s = 82$. Solving this system of equations, we get $s = 12$ and $f = 32$, so the son is 12 years old and the father is 32 years old.

Let the two-digit number be $10t+u$, where $t$ is the tens digit and $u$ is the units digit. We are given that $t+u=13$ and $2t-u=1$. Solving this system of equations, we get $t=7$ and $u=6$, so the two-digit number is $76$.

Let the two-digit number be $10x+y$, where $x$ is the tens digit and $y$ is the units digit. We are given that $2(10+x+y) = 27(10x+y)$, or $20+2x+2y = 270x+27y$. Simplifying this equation, we get $268x-25y = 10$. Since $y$ is a digit, we know that $0 \leq y \leq 9$. We can check that $x=1$ is too small, so we try $x=2$. Plugging in $x=2$, we get $536-25y=10$, which gives $y=21/5$, which is not a digit. Thus, there is no solution for a two-digit number.
