explanation: you multiply
Pythagorean theorem helps us find a sides measurements in a right triangle. the formula is a^2+b^2=c^2<span />
The answer would be 25200
Reason being because there is a number of ways when selecting (3 consonants out of 7) and (2 vowels out of 4)
= (7C3 x 4C2)
= 7 x 6 x 5 /3 x 2 x 1 x 4 x 3/ 2 x 1
= 210.
The number of groups each having 3 consonants and 2 vowels = 210.
Because each group contains 5 letters.
They have to be rearranged
5 letters among themselves = 5!
= 5 x 4 x 3 x 2 x 1
= 120.
Required number of ways = (210 x 120) = 25200.
Answer:
P= $29 and D = -$30
Step-by-step explanation:
4D + 5P = $25
5P = $25 - 4D
P = ($25 - 4D)/5 equation(i)
Noe substitute the value of P
3D + 4P = $26
3D + 4($25 -4D)/5 = $26
3D*5 + ($100 -16D)/5 =$26*5
15D + $100 - 16D =$130
-D = $130 - $100
D = -$30
Again substitute the vale of D in equation(i)
P = ($25 + 4D)/5
=$25 + 4*$30/5
=$25 + $120/5
=-$145/5
=$29
Step-by-step explanation:
42/154
21/77 ( divide by 2)
