Answer:

  7%

Step-by-step explanation:

The simple interest formula is ...

  I = Prt . . . . where P is the principal, r is the rate, and t is the number of years

Filling in the given values, we can solve for r.

  490 = 1400·r·5

  490/7000 = r = 0.07 = 7%

The interest rate was 7%.

Answer: No, it is linear

Explanation: The constant is +8, meaning the y intercept is 8. Proportional lines go through (0,0), but this line goes through (0,8).

√(6+x−x²)=9

the domain :

6+x-x² ≥ 0

(3-x)(2+x) ≥0

-2 ≤ x ≤ 3

problem solving:

√(6+x−x²)=9

6+x−x²=81

-x²+x+6-81 = 0

-x²+x-75 = 0

x²-x+75 = 0

Answer:

tan^2 60 - sin^2 45

= (√3)^2- (1/√2)^2

= 3-1/2

= 6-1/2

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

The exact value of tan(60) is sqrt(3), and sin(45) is 1/sqrt(2)

tan^2 (60) - sin^2 (45)

[tex]=(\sqrt{3})^2-(\frac{1}{\sqrt{2}} )^2\\=3-\frac{1}{2}\\ = \frac{5}{2}[/tex]

To give the patient a dose of 2g medication with a strength of 4g/0.4ml, you should administer 50 ml of the medication.

Given that,

Dose ordered: 2g of medication

Medication strength: 4g/0.4ml

Conversion factor: 10

To calculate the volume of medication you need to give the patient,

Use a simple formula:

Volume (in ml) = (Dose ordered / Strength) x Conversion factor

In this case,

The dose ordered is 2g and the strength is 4g/0.4ml.

To find the conversion factor,

Divide 4g by 0.4ml, which equals 10.

So, using the formula,

The volume of medication you need to give the patient would be:

Volume (in ml) = (2g / 0.4ml) x 10

Now, calculating this:

Volume (in ml) = 5 x 10

Hence, you should give the patient 50ml of medication.

The yellow line I drew is the line of reflection.

Answer:

Transposing a number is a type of error where two digits swap position in the sequence. An example would be to enter 13 instead of the desired 31. It could also be the error of dropping a needed zero as in writing 15 instead of the desired 150.

Step-by-step explanation:

Unless by "number" you mean musical score. Then transposing is rewriting the score in a new key.

Answer:

50 L of petrol is needed to travel 600 km.

Step-by-step explanation:

The car travels 1 km in 20/240 L of petrol.  

Then,  

Petrol needed to travel 600 km  

20/240 × 600  

20/24 × 60  

20/4 × 10  

5 × 10

= 50 L

Answer:

50 liters

Step-by-step explanation:

Petrol needed to travel 240 Km = 20 liters

Petrol needed to travel 1 Km = 20/240

Petrol needed to travel 600 Km = [tex]\frac{20}{240} * 600[/tex]

      = 50 liters

Step-by-step explanation:

The given equations are

x2+y3=xy9

⟹xy2y+3x=xy9

⟹3x+2y=9 ........(i) 

x4+y9=xy21

⟹xy4y+9x=xy21

⟹9x+4y=21   ........(ii)  

Now (i)×3⟶9x+6y=27   .....(iii)

Subtracting (iii) from (ii),

−2y=−6⇒y=3.

Putting y=3 in (i),

3x+2×3=9⟹x=1.∴(x,y)=(1,3)
