300,000 because you have to just multiply 150 by 200
Answer:
60
Step-by-step explanation:
There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.
Now, we can substitute this into the ratio of teachers to students:
teachers : students = 3 : 35
teachers : (male students : female students) = 3 : (10 : 25)
Then the number of teachers is seen to be 3/25 of the number of female students:
(3/25)(500) = 60 . . . teachers
Answer:
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Step-by-step explanation:
If the length of a minute hand of a clock is 3.5cm, to find the angle it turns through if it sweeps an area of 48 cm, we will follow the steps below;
area of a sector = Ф/360 × πr²
where Ф is the angle, r is the radius π is a constant
from the question given, the length of the minute hand is 3.5 cm, this implies that radius r = 3.5
Ф =? area of the sector= 48 cm² π =
we can now go ahead to substitute the values into the formula and solve Ф
area of a sector = Ф/360 × πr²
48 = Ф/360 × × (3.5)²
48 = Ф/360 × ×12.25
48 = 269.5Ф / 2520
multiply both-side of the equation by 2520
48×2520 = 269.5Ф
120960 = 269.5Ф
divide both-side of the equation by 269.5
448.8≈Ф
Ф = 448.8°
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Answer:
kshs 6,480,000
Step-by-step explanation:
Since, kshs 240,000 represent the 3% of the car price, you can use a rule of three to calculate the amount that represents 100%:
240,000 → 3%
x → 100%
x=(240,000*100)/3
x=8,000,000
So, the price of the car is kshs 8,000,000 and you can calculate the 16% of this, to find the amount that the dealer had to pay as government V.A.T:
8,000,000*16%=1.280.000
Now, you can subtract the comission and the government VAT from the car price:
8,000,000-240,000-1,280,000=6,480,000
According to this, the answer is that the dealer remained with kshs 6,480,000 from the sale of the car.
