Answer:
0.50 %
Step-by-step explanation:
= profit/cost x 100%
= 11.95 - 7.95 = 4
= 4/7.95 x 100 %
= 0.50 %
3+9= 12 12x7=84 84-21=63
so it is 21+63
Answer:
2/4=1/2
Step-by-step explanation:
It rises 2 runs over 4.
rise/run
2/4=1/2
Answer:
Distance of object = 0.0144 meter
Step-by-step explanation:
Given:
Angular diameter = 30 arcseconds = 30[100 / 3600]
Length of diameter = 10 cm
Find:
Distance of object
Computation:
Distance of object = [(2)(a)][TanФ / 2]
Distance of object = [(2)(10)][Tan(300 / 7200]
Distance of object = [20][Tan 0.04167]
Distance of object = [20][0.00072]]
Distance of object = 0.0144 meter
In the above problem, you want to find the number of multiples of 7 between 30 and 300.
This is an Arithmetic progression where you have n number of terms between 30 and 300 that are multiples of 7. So it is evident that the common difference here is 7.
Arithmetic progression is a sequence of numbers where each new number in the sequence is generated by adding a constant value (in the above case, it is 7) to the preceding number, called the common difference (d)
In the above case, the first number after 30 that is a multiple of 7 is 35
So first number (a) = 35
The last number in the sequence less than 300 that is a multiple of 7 is 294
So, last number (l) = 294
Common difference (d) = 7
The formula to find the number of terms in the sequence (n) is,
n = ((l - a) ÷ d) + 1 = ((294 - 35) ÷ 7) + 1 = (259 ÷ 7) + 1 = 37 + 1 = 38
