12 should be 25% just divide 10 by 40 which gives you .25 then multiply by 100 and that gives you 25%
20 should be 33.33& divide 7 by 21 that gives you .3333 muliply by 100 that gives you 33.33%
21 should be 7.5 since you multiply the percent by the whole to get the part which would be .15 multiply by 50 which is 7.5
Answer:
h=78.4
Step-by-step explanation:
2/1.25 = h/49
Cross multiplication
1.25h = 2x49
1.25h=98
h= 78.4
CHECK:
2/1.25 = 1.6
78.4/49=1.6
It's the second one which is B becasue, first you minus 3w on both sides of your equal side. Then you will have 3L=18-3w. Next you will have to divided by 3 on both sides of the equal sign, you will have L=18-3w/3. Afte that you will simipfy and get your answer, which is B. Please get a brainiest point.
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
y = P(1 + r/n)^nt
Where
y = the value of the investment at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount invested
From the information given,
P = $4700
r = 4.75% = 4.75/100 = 0.0475
n = 1 because it was compounded once in a year.
Therefore, the exponential function showing the relationship between y and t is
y = 4700(1 + 0.0475/1)^1 × t
y = 4700(1.0475)^t
Answer:
