Answer:

Step-by-step explanation:

The answer is B. His budget is $250 so it has to be less than or equal to. $60 a crew member (x = the crew members) and $45 to use the forklift, so $60x + $45 is less than or equal to $250

Answer:

B is the correct answer.

Step-by-step explanation:

According to the problem, the contractor can spend AT MOST $250 a day, meaning $250 is the limit. Therefore, that gives you less than or equal too, or ≤. Next, it costs $45 a day, including $60, which you would add to get the final amount, or +.

Therefore, 60x + 45 ≤ 250

Answer:

- [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

2y = - 3x - 8 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x - 4 ← in slope- intercept form

with gradient = - [tex]\frac{3}{2}[/tex]

The gradient of the straight line 2y = -3x - 8 will be -1.5.

A straight line is a combination of endless points joined on both sides of the point.

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
The slope(gradient) 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the equation of the line is, 2y = -3x - 8

Rearrange the equation in the standard form of the equation as

2y = -3x - 8

y=-3/2 x-8/2

y= -1.5x - 4

Compare the obtained equation with the standard equation,y=mx+b. Where m is the gradient of the straight line.

m= -1.5

Thus, the gradient of the straight line 2y = -3x - 8 will be -1.5.

The number of cartons that the oranges would fill in  Bob’s Citrus and Nursery would be 235 cartons.

The number of grapefruits in each bin would be 241 grapefruits per bin.

To find the number of cartons of oranges that would be filled, use the number of oranges that go into carton in Bob’s Citrus and Nursery and the number of oranges they have to pack. The formula would be:

= Number of oranges / Number of oranges per carton

= 5, 643 / 24

= 235 cartons

The same logic is applied to find the number of grapefruits that would be in each bin. If each bin would have an equal number of grapefruits, the number of grapefruits per bin would be:

= Number of grapefruits / Number of bins

= 4, 338 / 18

= 241 grapefruits per bin

Answer:

equation 1

y = -2x

equation 2

y = x-3

Solution to both

(1,-2)

Step-by-step explanation:

We need to get the equations of both lines

General form is;

y = mx + c

where m is slope and c is the y-intercept

Table 1

since we have a point 0,0; the y-intercept here is zero

Let us get the slope. We can do this by selecting any two points

m = (y2-y1)/(x2-x1)

m = (2-10)/(-1+5) = -8/4 = -2

So the equation of the first line is;

y = -2x

Table 2

we get the slope

m = (4+2)/(7-1) = 6/6 = 1

The partial equation is;

y = x + c

To get c, we select any two point and substitute

4 = 7 + c

c = 4-7

c = -3

So the equation is;

y = x-3

To get the solution to both systems, we equate the y

-2x = x - 3

-2x-x = -3

-3x = -3

x = -3/-3

x = 1

To get y, we substitute;

recall; y = -2x

y = -2(1)

y = -2

Solution to the system is;

Answer:

It takes 1 year.

Step-by-step explanation:

You have to apply simple interest formula, I = (P×R×T)/100 where I represent interest amount, P is principle, R is interest rate and T is number of years :

[tex]I = \frac{PRT}{100} [/tex]

[tex]200 = \frac{4000 \times 5 \times T}{100} [/tex]

[tex]20000 = 20000T[/tex]

[tex]T = 1[/tex]

We, know that :

[tex] \underline{\boxed{\sf Interest \: amount = \dfrac{Principal \times Rate \times Time}{100}}}[/tex]

[tex] \underline{\boxed{\sf I = \dfrac{P \times R \times T}{100}}}[/tex]

By putting values, we have

[tex] \sf : \implies 200 = \dfrac{4000 \times 5 \times T}{100}[/tex]

[tex] \sf : \implies 200 \times 100 = 20000 \times T[/tex]

[tex] \sf : \implies 20000 = 20000 \times T[/tex]

[tex] \sf : \implies \cancel{\dfrac{20000}{20000}} = T[/tex]

[tex] \sf : \implies 1 = T[/tex]

[tex] \underline{\boxed{\sf T = 1 \: year}}[/tex]

Answer:

  32.9

Step-by-step explanation:

The ratio of long side to hypotenuse is the same for all of the triangles in the figure.

  AD/AB = AB/AC

  AB^2 = AD·AC = 30·36

  AB = 6√30 ≈ 32.863

To the nearest tenth, AB ≈ 32.9.

Answer:

b = 4

Step-by-step explanation:

a^2 + b^2 = c^2

a = 3

b = b

c = 5

a^2 + b^2 = c^2

(3)^2 + b^2 = (5)^2

9 + b^2 = 25

b^2 = 25 - 9

b^2 = 16

√b^2 = √16

b = 4

Step-by-step explanation:

P prime of t indicates a rate of change

The required expression that gives the rate of the population of the city will be changing at time t=5 is D) P'5. Option D is correct.

Given that,
A city planner developed the function P to model the population of a city over the next 25 years, where P(t) is the projected population of the city t years from now.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
The rate of the population expression at t = 5 is given by the differentiation of the expression at t = 5 because differentiation represents the rate for the given equation of population. i.e.
P'5

Thus, the required expression that gives the rate of the population of the city will be changing at time t=5 is D) P'5. Option D is correct.

Answer:

k ≠ 3

Step-by-step explanation:

Given the system of equation;

kx - y = 2 ------------------- 1

6x - 2y = 3 -------------------- 2

Rewriting the equations in the format ax+by+c = 0

Equation 1 becomes kx - y - 2 = 0

Equation 2 becomes 6x - 2y - 3 = 0

where a₁ = k, b₁ = -1 and c₁ = -2  and a₂ = 6, b₂ = -2 and c₂ = -3

For the system of equation to have a unique solution the following must be true;

a₁/a₂ ≠ b₁/b₁

Substituting the coefficients into the condition, we will have;

k/6 ≠ -1/-2

k/6 ≠ 1/2

Cross multiplying we will have;

2k ≠ 6

k ≠ 6/2

k ≠ 3

This means that k can be any other real values except 3 for the system of equation to have a unique solution.

1) 1.2 cm, 0.6 in, 0.031 m, 0.1 ft

The relationship between the units is given as;

m > ft > in > cm

Upon converting the rest units to the lowest;

0.6 in = 1.524 cm

0.031 m = 3.1 cm

0.1 ft = 3.048 cm

The order is given as;

0.031 m > 0.1 ft > 0.6 in > 1.2 cm

2) 2 lb, 891 g, 1 kg, 0.02 T

2 lb = 907.185 g

1 kg = 1000 g

0.02 T = 20000 g

The order is given as;

0.02 T >  1 kg > 2 lb > 891 g

3) 1 1/4 c, 0.4 L, 950 mL, 0.7 gal

0.4 L = 400 mL
