ITS 2
Step-by-step explanation:
Answer:
Not sure but :
Y=15/7
X=13/5
Z=26/7
I will check them later and tell you if they are right or not .
Step-by-step explanation:
y power 2 : 31 × 8 = 248
Rad 248 = 15/7
x power 2 : 23 × 8 = 184
Rad 184 = 13/5
31 power 2 : (15/7) power 2 + z power 2
961 = 246/49 + z powe 2
z power 2 = 714/51
rad 714/51 = 26/7
z = 26/7
Answer:
A) 60
B) 72/300
C) 150
Step-by-step explanation:
A) P(green) = ⅕
⅕ × 300 = 60
B) purple: 72
45+37+52+94+72 = 300
Therefore, 72/300
C) 1000 × (45/300)
150
A two-digit number is twice the sum of its digit. If the tens digit is 7 less than the unit digit, find the number.
Let x= the unit digit
Then y= the tens digit
<span>And 10y+x= the number
</span>x+y= the sum of the digits
<span>Now we are told that 10y+x=2(x+y) ------1st equation </span>
<span>We are also told that y=x-7 ----------- 2nd Equation </span>
<span>So our equations to solve are: </span>
(1) 10y+x=2(x+y)
<span>(2) y=x-7
</span>
Hope it helps
√65Explanation:(−5,1)=x1,y1(3,0)=x2,y2The distance is calculated using formula:'Distance =√(x2−x1)2+(y2−y1)2=√(3−(−5))2+(0−1)2=√(3+5)2+(−1)2=√(8)2+(−1)2=√(64+1)Distance =√65
