Angles around a point
Answer:
205°
Step-by-step explanation:
The total circle is 360°. The right angle is 90°, and you know the other angle is 64°. 90° + 64° is 154°. 360° -154° is 205°.
Answer:
We know that the angle around any given point is 360°
Therefore, according to the given problem,
[tex]x° + 64° + 90° = 360° \\ x° + 154° = 360° \\ x° = 360° - 154° \\ \boxed{x° = 206°}[/tex]
Hence, the value of x° is 206°
x° = 206° is the right answer.find (f.g)(-3)when f(x)=-5x-7 and g(x)= 7x^2-2x+9
Answer:

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

How do you transpose a number
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.
Find the domain and solve: √(6+x−x2)=9
Step-by-step explanation:
√(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
D = 1² -4(1)(75) = 1-300 = -299

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.

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
