I take it that the actual total is 538. If it really is 538538 leave me a note.
Let the first number = x
Let the second # = 44x
Let the third # = 100x
Equation
x + 44x + 100x = 538 Add the left side. All terms are part of the total.
145x = 538 Div By 145
x = 538/145
x = 3.71
Check
First number = 3.71
Second # = 44*3.71 = 163.24
Third number = 100*3.71 = 371
Total these 3 numbers 537.95 The very tiny difference is due to rounding.
Answer:
27.3
Step-by-step explanation:
y=a(1/2)^t/h
Plug in
22=30(1/2)^t/61
Divide both sides by 30
0.7333333333=(1/2)^t/61
Log both
Log(0.7333333333) / Log(1/2)
0.447458977 = t/61
0.447458977 x 61 = t
27.2949976 to the nearest tenth is 27.3 = t
$34.00 + .08x = total
34 + .08(299)
=34 + 23.92
= 57.92 would be the highest
D 2:1, because a dime is worth twice as much as a nickel
Because the question has number of nickels listed first in the ratio that makes the answer 2:1 as opposed to B 1:2. Also, two nickels equal the same amount as one dime so for every two nickels there is one dime. In this case, there are 728 nickels and 364 dimes. 728/364 = 2/1 (simplifies down to the fourth ratio given)
