Answer:

36.25

Step-by-step explanation:

You need to find out how much he makes an hour. To do that you divide how much he made by 13 hours. Which was 7.25. Than multiply 7.25 by 5. And you get your answer which is 36.25.

The same goes for any money scenario when you are trying to find out like how much an individual 'peach' is in the whole bag. Or take it for what you will it was an example.

The general formula that describes the variation is T² = 18a³/d²

          x ∝ y.

          This can then be written as;

           x = ky

           Where;

           k = constant rate of change.

            x ∝ (y/z)

           This can then be written as;

            x = k (y/z)

           Where;

           k = constant rate or variation

The square of T varies directly with the cube of a and inversely with the square of d.

Note that

square of T = T²

cube of a = a³

square of d = d²

Therefore, we can write;

T² ∝ a³/d²

T² = k (a³/d²)

Since;

T = 4 when a = 2 and d = 3

We can find the constant of proportionality k, by substituting the values of T=4, a = 2 and d = 3 into equation (i) and solve as follows;

(4)² =  k (2³/3²)

16 =  k (8/9)

8k = 16 x 9

8k = 144

k = 144/8

k = 18

Therefore, The overall formula for describing the variation is

T² =  18 a³/d²

The Initial amount is 14.76 and the decay factor is 1.4 while the percentage rate of change is 40%.

We are given the function as;

y = 1.4^(t + 8)

Now, the general formula for an exponential decay function is;

f(x) = abˣ

where;

a = initial amount

b = decay factor

x = number of time intervals

Now, using laws of exponents, our initial function can be written as;

y = 1.4⁸ × 1.4^(t)

Now, 1.4⁸ = 14.76

Thus, we now have the expression as;

y = 14.76(1.4^(t))

Comparing with the general equation of exponential decay gives us;

14.76 = initial amount

1.4 = decay factor

t = number of time intervals

If decay factor is 1.4, then this denotes 140% which means that the percentage rate of change is 40%

The above statement describes the equation of a circle whose endpoints of a diameter are (-0,0) and (4,-6):

(x + 2)² + (y + 3)² = 3.6

The simple form equation of a circle is: (x – x1)² + (y – y1)²= r², where (x, y) are arbitrary coordinates upon that circumference of the circle, r seems to be the radius of the circle. and (x1, y1) are indeed the coordinates of the circle's center.

Given points are:

(-0,0) and (4,-6)

Find that diameter's length using the locations of the locations as well as the distance formula.

d = √((x₂ - x₁)² + (y₂ - y₁)²)

  = √((4 - (-0))² + (-6 - 0)²)

 = √((4 )² + (-6 )²)

= √(16 + 36)

= √(52)

= 7.2

Radius will be r/2

7.2/2

= 3.6

To obtain the coordinates of the center, use the interest in obtaining and the midpoint formula.

[tex]C=\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}[/tex]

C = (-0 + 4)/2 , (-6 + 0)/2

C = -2 , -3

To write this circle equation, use the radius and the center coordinates.

(x - h)² + (y - h)² = r²

(x - (-2))² + (y - (-3))² = 3.6

(x + 2)² + (y + 3)² = 3.6

The van can carry 13 students and the bus can carry 53 students.

A van can carry = 13

A bus can carry = 53

The equations will be derived from the conditions given in the question:

Let x be the no. of students in van

Let y be the no. of students in bus

     13x + 9y = 646……………(1)

      6x + 3y = 237………………(2)

Multiplying (2) with 3

13x + 9y = 646……………(3)

18x + 9y = 711 …………...(4)

Subtracting equation (3) from (4)

18x + 9y = 711

- (13x + 9y = 646)

We get:

5y = 65

y = 13

Now, plug the value of y into one of the preceding equations:

13x + 9(13) = 646

Solving this we get

x = 53

Hence, The van can carry 13 students and the bus can carry 53 students

a) He will start 900 feet from the edge

b) 16 Round trips are needed to cover the field.

Because Mr. Johns intends to check a wheat field 960 feet wide for weeds so he will distribute a 60-foot wide strip using a high clearance sprayer that has two 30-foot booms.

a) 960 foot - 60 foot = 900 foot

Therefore, he should start 900 feet from the edge.

b) 960 foot / 60 foot = 16 Trips.

Therefore, 16 round trips are needed to cover the field.

The simplest form of the ratio 35:30 is 7/6.

Given, the ratio is 35:30

By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part to part ratio, whereas the second is a part to whole ratio. The relationship between two separate entities or organizations is shown by the part-to-part ratio.

We can refer to a fraction as being in its simplest form when it cannot be further spelled out or reduced. Divide the denominator and numerator by their respective least common multiples to reduce a fraction.

divide the numbers by 5
