hhhhhh
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)
Answer:
i

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]

A car travels 240 km on 20 liters of petrol. how many litres of petrol is needed to travel 600 km
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
A dose of 2g of medication has been ordered for patient.The medication comes in 4g/0.4ml.What volume will you give the patient?
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.

find the whole number quotient and remainder for 52 divided by 8
Answer:
6.5
Step-by-step explanation:
Answer:
6.5
Step-by-step explanation:
Using a calculator, if you typed in 52 divided by 8, you'd get 6.5. You could also express 52/8 as a mixed fraction: 6 4/8. If you look at the mixed fraction 6 4/8, you'll see that the numerator is the same as the remainder (4), the denominator is our original divisor (8), and the whole number is our final answer (6).

the area of a rectangular place mat is 98 inches its length is seven inches longer than the width. find the length and width of the place mat
A
Answer:
width is 7, length is 14
Step-by-step explanation:
x(x+7) = 98
x^2 + 7x = 98
x^2 + 7x - 98 = 0
( x + 14 )( x - 7 ) = 0
x+14=0 results in negative measures
x-7=0 ---> x= 7
width is 7, length is 14

A real estate office pays its salespeople a weekly retainer of $220 plus commission of 2.5% for the first
$200 000 of the value of each property sold and 2% of each amount after that. Calculate the commission
received if the following houses are sold.
7- The commission for the sale of a $ 540,000 house was $ 12,020.
8- The commission for the sale of a $ 795,600 house was $ 17,132.
9- The commission during the 4 weeks of February was $ 24,690.
10- The commission during the 4 weeks was $ 27,754.
11- The house was worth $ 440,000.
Given that a real estate office pays its salespeople a weekly retainer of $ 220 plus commission of 2.5% for the first $ 200,000 of the value of each property sold and 2% of each amount after that, to determine the commission received if the following houses are sold, the following calculations must be performed:
7- a $ 540,000 house 540,000 - 200,000 = 340,000 220 + (200,000 x 0.025) + (340,000 x 0.02) = X 220 + 5000 + 6800 = X 12020 = X
8- a $ 795,600 house 795,600 - 200,000 = 595,600 220 + 5000 + (595,600 x 0.02) = X 5220 + 11912 = X 17132 = X
9- a $ 472,500 house and a $ 618,000 house 472,500 - 200,000 = 272,500 618,000 - 200,000 = 418,000 220 x 4 + 5000 + (272,500 x 0.02) + 5000 + (418,000 x 0.02) = X 880 + 10,000 + 5,450 + 8,360 = X 24,690 = X
10- a $ 384,000 unit, a $ 216,000 unit and a $ 593,700 house 384,000 - 200,000 = 184,000 216,000 - 200,000 = 16,000 593,700 - 200,000 = 393,700 880 + 5000 x 3 + (184,000 x 0.02) + (16,000 x 0.02) + (393,700 x 0.02) = X 15880 + 3680 + 320 + 7874 = X 27.754 = X
11- the value of a house whose commission is $ 9800 200,000 x 0.025 = 5000 9800 - 5000 = 4800 2 = 4800 100 = X 100 x 4800/2 = X 240,000 = X 240,000 + 200,000 = 440,000
