Step-by-step explanation:
= 2*5^4 + 4*5^3 + 4*5^2 + 0*5^1 + 3*5^0
= 2*625 + 4*125 + 4*25 + 0*5 + 3*1
=1250 + 500 + 100 + 0 + 3
= 1853 base 10
1853 divided by 8 = 231 r 5
231 divided by 8 = 28 r 7
28 divided by 8 = 3 r 4
3 divided by 8 = 0 r 3
Therefore the answer is 3475 base 8
Answer:
<RQP
Step-by-step explanation:
The vertex must either be the name of the angle or in the middle of the letters
<PQR or <RQP
We can also just call it <Q since there is only one angle
Answer:
Step-by-step explanation:
a ) Let the volume required be v .
v x .8 + 500 x .3 / ( v + 500 ) = .7
.8 v + 150 = .7 v + 350
.1 v = 200
v = 2000 mL
b )
Let the volume of solution A required be v . The volume of solution of B required will be 100 - v
v x .8 + ( 100 - v ) x .3 / 100 = .5
.8 v + 30 - .3 v = 50
.5 v = 20
v = 40 mL
volume of solution B = 60 mL .
c )
It is not possible because 90 % is more than 80 % the concentration of solution A . Any mixture will have concentration less than 80 % .
volume of solution B = 60 mL
Answer:
Amy makes more money
Step-by-step explanation:
Allison:
works 15hr
makes $5.25 per hr
(5.25)15 = 78.75
Allison makes 78.75 per week.
Amy:
works 15hr
makes 3.10 per hour
(3.10)15 = 46.50
plus 38 in tips
46.50 + 38 = 84.50
Answer:
2/5 = 4/10
4/10 = 40%
Explanation:
2/5 is a simplified fraction, and one of the bigger fractions it’s made by 4/10. Do you can use 4/10, but can also use 8/20, 20/50, 40/100, so on. Since we know that any fraction that of ten can be turned into a percentage easily (2/10=20%, 5/10=50%,9/10=%90), then 4/10 is equal to 40%. So 40% of the people in Jeremiah’s class are boys.
