Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
Hello!
The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10
Multiply these two numbers
7/10 * 3 / 10 = 21/100
21/100 = 0.21
The answer is 0.21 or 21%
Hope this helps!
Answer:
48/37 + (8/37)i.
Step-by-step explanation:
8 / (6 - i)
We multiply top and bottom of the fraction by the conjugate of 6 - i , which is 6 + [email protected]
= 8*(6 + i) / (6 - i)(6 + i)
= 48 + 8i / (36 + 6i - 6i - i^2)
= 48 + 8i / (36 - (-1))
= 48 + 8i / 37
= 48/37 + (8/37)i.
A percentage is simply a special type of fraction with a divisor of 100 and the numerator shown beside the percent sign. So 50% is really 50/100, which reduces to 1/2.
