Answer:

the exact value is x =1/2 or x=0.5

your welcome!

The exact value is x = 1/2.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given an expression as;

[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]

Now we can see that

27 = 3³

9 = 3²

Then the power are 3(-1/3) = -1

3(1/4) = 3/4

So we have;

[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]

So,

-2 = -2r - 1

-2r = -1

r = 1/2

Answer:

7) is $1.70

8) is 8 miles per hour

9) is Store A is the better buy

10) is 222

11) is the area is 6

12) is the range is 14

8.)8 miles per hour

20 = 150

X = 60

20 x 60 = 150x

1200 = 150x

X = 8

9.)better buy number A

44.68 /16 = 2.7925

31.57 /11 = 2.87

11.) The area of this figure is 6

3 X 2 = 6

12) Range of the data set is 14

15 - 1 = 14

Answer:

-1 ; -1 ; the two lines are parallel

Step-by-step explanation:

To find the slope of the two lines, we can proceed in two different ways:

1) the faster is do the division: -a/b where a is the number the multiplies x and b is the number that multiplies y

line 1: m = 3/-3 = -1   line 2: -4/4 = -1

2) the second is to rewrite the two equation in the slope intercept form and find what term multiplies the x

line 1

-3y = 3x+6

-y = x + 2

y = -x -2

m = -1

line 2

x+y = 2

y = -x +2

m = -1

the two lines have the same slope, so they are parallel

Answer:

there is 243.84 cm in 8 feet

round to the nearest hundredths =3266.53

Answer: The third option

Step-by-step explanation:

(6) (5) is the area of the quadrilateral, therefore you subtract that value by the area of the semi-circle.

to find the area of a semi circle the formula is: (1/2) π ( [tex]r^{2}[/tex])

The radius is 2.5 because the diameter is 5, and the radius is half the diameter.

Answer:

V = 336 ft3

Step-by-step explanation:

1/2*7*16*6

336

Answer: 336 ft cubed

Step-by-step explanation:

Formula is 1/2 times B times L times H so, 7 times 6 is 42, 42 times 16 is 672 and 672 divided by 2 or multiplied by 1/2 is 336

Answer:

1) $52,000

2) $43,200

3) P = 325 × x + 180 × y

4) x + y ≤ 240

2·x + y ≤ 320

325 × x + 180 × y ≤ 52,000

5) Please find a similar graph created with MS Excel

6) Corn will have 80 acres

Soybean will have 160 acres

7) $54,800

Step-by-step explanation:

The acres of cropland at the Waterbrook Farm, A = 240 acres

The profit per acre in corn production, p₁ = $325

The profit per acre in soybean production, p₂ = $180

The hours of labor required by each acre of corn = 2 hours

The hours of labor required by each acre of soybeans = 1 hours

The number of acres planted with corn = x

The number of acres planted with soybeans = y

1) The farm's profit, 'P', if they planted only corn is P = p₁ × A

∴ P = $325/acre × 320 hours/(2 hours/acre) = $52,000

The farm's profit if they planted only corn, P = $52,000

2) The farm's profit, 'P', if they planted only corn is P = p₂ × A

The required labor for cultivating the 240 acres at 1 hour/acre = 240 hours of labor

Therefore, the labor is sufficient for the entire farmland, we get;

The profit, P = $180/acre × 240 acres  = $43,200

∴ The farm's profit if they planted only soybeans, P = $43,200

3) The equation for the Waterbrook Farm's profit, 'P' can be found, depending on the area of the farm used for the corn and the soybeans as follows;

P = 325 × x + 180 × y

4) The system of inequalities includes;

x + y ≤ 240

2·x + y ≤ 320

325 × x + 180 × y ≤ 52,000

5) Using DESMOS, we have;

The graph of the systems of inequalities is plotted and a graph similar to the attached graph created with MS Excel is found

6) The maximum profit point found using DESMOS is (80, 160)

Therefore, for maximum profit, 80 acres should be used for corn while 160 acres should be used for soybeans

7) The maximum profit of planting both corn and soybeans is found from the profit obtained from the land divided between corn and soybeans in order to yield maximum profit as follows;

P = 325 × 80 + 180 × 160 = 54,800

The maximum profit of planting both corn and soybeans, P = $54,800.

Answer:

3/10. 0.3

Step-by-step explanation:

when you divide mixed numbers you should reciprocate them I mean take the reciprocal and that was 2 and over every number there is one so I took 1/2 hope you understand why I kept 1/2 I took its reciprocal hope you understand if I'm wrong tell me right away I'll try it out good luck.

Answer: $6.75

Step-by-step explanation:

25 hours times $9= $225/week

3% increase from $9.00= $0.27

$9.27 times 25 hours= $231.75

$231.75-$225= $6.75 more per week
