3 full shifts of 3/4 hour and 1 half shift of 3/4 hour

Shift work is an employment strategy intended to utilize or give service during each of the seven days of the week's full 24 hours. The day is often divided into shifts, predetermined times when various groups of workers carry out their tasks.

Total work hours = 2.625 hours

Each shift = 0.75 hr

Number of shifts = Total work hours / Each shift

                            = 2.625 / 0.75

                            = 3.5

Therefore, He worked three full shifts of three hours each and one half-shift of three hours.

3230 Kilograms of the soil supplement are required for the entire Vineyard.

Some units that need to be recalled are as follows:

1 km = 1000 m

1 km^2 = 1000000 m^2

1 km^2 = 247 acres

1 kg = 1000 g

Let's tackle the problem now:

A vineyard has 145 acres of Chardonnay grapes.

145 acres = [tex]\frac{145}{247}[/tex]× 1 km^2

145 acres = 145/247 km^2

145 acres ~ 0.587 km^2

A particular soil supplement requires 5.50 grams for every square meter of vineyard

1m^2 → 5.50 gram

1 km^2 = 10^6 →5.50 x 10^6 gram

1 km^2 →5.50 x 10^6 x 10^-3 kg

1 km^2 →5.50 x 10^3 kg

145 acres = 145/247 km^2 →145/247 x 5.50 x 10^3 kg

145 acres → 797500/247 kg

145 acres → 3230 kg

It required 797500/247 kg ~ 3230 kg of the soil supplement for the entire Vineyard.

The slope of equation  y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4

The slope of a function y = f(x) is given by a formula

slope = y2-y1 / x2- x1

where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)

Or we can simply use the slope-intercept form

y = mx+ c

where m is the slope of the given equation and c is the constant

so, in  the given equation y = -5/6 x + 4

slope of the equation is -5/6

Hence, The slope of equation  y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4

When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.

The given parameters are

C = (1, 6)

The ratio 3/4 can be represented as:

m : n = 3 : 1

So, the coordinate of point E is

E = 1/(m + n) * (mx2 + nx1, my2 + ny1)

So, we have:

E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)

The truth value of the conditional statement is false

How to determine the truth value of the conditional statement?

The conditional statement is given as

“If a number is greater than -500, then the number is greater than 500.”

The above conditional statement is false

This is because not all numbers greater than -500 are greater than 500

for example 450 is greater than -500, but less than 500 that is the number between -500 and 500 will not satisfy the above statement.

Hence, the truth value of the conditional statement is false

Answer:

[tex]\frac{31}{33}[/tex]

Step-by-step explanation:

You need a common denominator to add.  The smallest number that is divisible by both 11 and 3 is 33.  Rewrite both fractions with a denominator of 33

[tex]\frac{3}{11}[/tex] x [tex]\frac{3}{3}[/tex]         [tex]\frac{3}{3}[/tex] is just another name for 1.  We are making an equivalent fraction.  Multiple 3 x3 for the top and 11 x 3 for the bottom to get:

[tex]\frac{9}{33}[/tex]

Do the same for [tex]\frac{2}{3}[/tex]

[tex]\frac{2}{3}[/tex] x [tex]\frac{11}{11}[/tex]       [tex]\frac{11}{11}[/tex] is just another name for 1.  We are making an equivalent fraction.  Multiple 2 x 11 for the top and 3 x 11 for the bottom to get:

[tex]\frac{22}{33}[/tex]

Now add these two fractions together:

[tex]\frac{9}{33}[/tex] + [tex]\frac{22}{33}[/tex] = [tex]\frac{31}{33}[/tex]

The new length of the string that Ed have now is  16.25 feet.

Fraction is some part of a total quantity.

Ed has a kite and a string of length[tex]7\frac{3}{4}[/tex] feet which is = [tex]\frac{31}{4}[/tex] feet.

He wants to extend the sting length so he added another 8.5 feet which is

= [tex]\frac{17}{2}[/tex] feet.

∴ The total length of the string will become

(31/4) + (17/2) feet.

= (31 + 34)/4 feet.

= 65/4 feet.

= 16.25 feet.

So, after he extended his string it has a length of 16.25 feet.

Answer:

To find the new length of the string, we need to add the length of the new piece of string to the existing length.

The current string length is 7 and 3/4 feet. This can be written as a mixed number, 7 + 3/4 = 7 3/4.

The new piece of string measures 8.5 feet.

To add these two lengths, we can convert the mixed number to an improper fraction and then add the fractions together.

7 3/4 can be converted to an improper fraction as (7 * 4 + 3) / 4 = 31/4.

Now we can add the fractions:

31/4 + 8.5 = (31/4) + (8.5 * 4/4) = 31/4 + 34/4 = 65/4

To simplify the fraction, we can divide the numerator (65) by the denominator (4) to get the whole number part and the remainder.

65 ÷ 4 = 16 remainder 1

So the new length of the string is 16 1/4 feet.

Therefore, the new length of the string is 16 and 1/4 feet.

The constant percent rate of change is of 4%

Using compound interest, it is found that the constant percent rate of change is of 4%.

The formula for an amount of money invested into compound interest is given by:

[tex]A(t) = A(0)(1+r)^{t}[/tex]

In which:

A(t) is the amount after t years.

A(0) is the initial amount.

r is the constant percent rate of change.

t is the time.

The function is:

[tex]g(x)=300(1.04)^{x}[/tex]

Thus, for the constant percent rate of change:

1+r = 1.04;

r = 0.04;

0.04 × 100% = 4%

The constant percent rate of change is of 4%.

Step-by-step explanation:

Got it right on my quiz.

The equation of the parabola that models the situation is given by:

(x - 1)² = -16(y - 5).

The equation of a quadratic function, of vertex (h,k), is given by:

(x - h)² = 4p(y - k).

The focus is located at point (h, k + p).

For this problem, to find the values of the parameters h and k, we have that:

Hence:

h = 1, k = 5.

And:

(x - 1)² = 4p(y - 5).

For the focus, and subsequently to find parameter p, we have that:

Hence:

k + p = 1.

5 + p = 1

p = -4.

Then the equation of the parabola that models this situation is given by:

(x - 1)² = 4p(y - 5).

(x - 1)² = 4(-4)(y - 5).

(x - 1)² = -16(y - 5).
