Answer:

0.20 dollar per oz and Joshua brought 16 oz of strawberry

Step-by-step explanation:

1 lbs = 16 oz

3.20÷ 16

= 20 cent

20 cent per one ounce of strawberry

1 cent = 0.01 dollar

20 cent = 20 × 0.01

20 cents = 0.2 dollar

Answer: See explanation

Step-by-step explanation:

1. Complementary (adds up to 90°)

2. Neither

3. Supplementary (ads up to 180°)

4. Adds up to 90° since its complementary

22 + 4x = 90

Subtract 22 from both sides

4x = 68

Divide both sides by 4

x = 17

5. Adds up to 90° since its complementary

65 + x + 2 = 90

x + 67 = 90

Subtract both sides 67

x = 23

6. Adds up to 90° since its complementary

43 + x - 7 = 90

x + 36 = 90

Subtract both sides by 36

x = 54

7. Adds up to 180° since its supplementary

29 + x - 5 = 180

x + 24 = 180

Subtract both sides by 24

x = 156

8. Adds up to 180° since its supplementary

110 + 7x = 180

Subtract both sides by 110

7x = 70

Divide both sides by 7

x = 10

9. Adds up to 180° since its supplementary

72 + x + 4 = 180

x + 76 = 180

Subtract both sides by 76

x = 104

10. Adds up to 90° since its complementary

49 + x + 3 = 90

x + 52 = 90

Subtract both sides by 52

x = 38

11. Adds up to 180° since its supplementary

92 + x + 78 = 180

x + 170 = 180

Subtract both sides by 170

x = 10

12. Adds up to 180° since its supplementary

19 + x - 50 = 180

x - 31 = 180

Add 31 to both sides

x = 211

13. Supplementary angles add up to 180°

∠C + ∠D = 180

∠C + 45 = 180

Subtract both sides by 45

∠C = 135°

The correct expression will be ( x- 4 ). So option B is right.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression will be solved as:-

E = ( - √(x-4))²

The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.

E = -√(x-4) x -√(x-4)

E = x - 4

Therefore the correct expression will be ( x- 4 ). So option B is right.

Answer:

Step-by-step explanation:

The amount of units that must be sold to a number yields a maximum profit is 600. Hence 600 units will be the correct option.

To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.

After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.

If the double derivative got negative then it will be maxima.

Given that function

f(x) = -0.001(x-600)² + 90

By differentiation

[tex]$f'(x)$[/tex] = -0.002(x - 600) + 90

Now equate with zero

-0.002(x - 600) + 90 = 0

x - 600 = 0

x = 600

Now checking the x at double derivative

[tex]$f''(x)$[/tex] at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.

wrote on NEML, got it right,

Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds. The millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Given information

All three cars can travel the same distance on a tank of gas.

The second car gets 6 kilometres per liter more than the first, but its tank holds 3 fewer liters than the first.

The third car gets 6 kilometres per liter less than the first, but its tank holds 6 more liters than the first.

Suppose the first car runs m. kilometre per liter. Then the second car will run (m+6) kilometre per liter and third car runs (m-3) kilometre per liter.

Suppose the first car has l liter in the tank. Then the second car has (l-3) liter and third car has (l+6) liters in her tank.

Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds.

As the distance traveled by the first car is same as the second one. Hence,

[tex]\begin{aligned}\\\dfrac{m}{l} &=\dfrac{m+6}{l-3} \\ml-3m&=ml+6l\\m&=-2l\\\end[/tex]

Let the above equation is equation 1.

As the distance traveled by the second car is same as the third one. Hence,

[tex]\begin{aligned}\\\dfrac{m-3}{l+6} &=\dfrac{m+6}{l-3} \\ml-3m+9-3l&=ml+6l+6m+36\\l+m&=-3\\\end[/tex]

Put the value of m in the above equation from equation 1,

[tex]l-2l=-3\\l=3[/tex]

[tex]m=2\times3=6[/tex]

Thus the value of the m is 6.

With the millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Answer:

Inequality representation :

18 + 25t ≤ 143 ;

t = 5

Step-by-step explanation:

Given that:

Initial dive, I = 18 feets

Descent rate, r = 25 feets / minute

Maximum depth reached = 143 feets

Time = t

Inequality representation :

18 + 25t ≤ 143

To solve for t

25t ≤ 143 - 18

25t ≤ 125

Divide both sides by 25

25t / 25 ≤ 125 / 25

t ≤ 5

Actual Dimension of bedroom = 10' * 8'

In the model ; longer side = 3 inches

Length of shorter side in the model ;

Longer side of actual bedroom = 10'

Scale factor * length = model length

Scale factor * 10 = 3

Scale factor = 3/10

Hence, length of shorter side :

Scale factor * actual length of shorter side

3/10 * 8

24 / 10

= 2.4 inches
