Answer:
<em>After </em><em>47</em><em> days she will have more than 90 trillion pennies.</em>
Step-by-step explanation:
At the beginning there was 1 penny. At the second day the amount of pennies under the pillow became 2.
The amount of pennies doubled each day. So the series is,
This series is in geometric progression.
As the pennies from each of the previous days are not being stored away until more pennies magically appear so the sum of series will be,
where,
a = initial term = 1,
r = common ratio = 2,
As we have find the number of days that would elapse before she has a total of more than 90 trillion, so
Answer:
7=-4x+7
Step-by-step explanation:
the formula of slope intercept form is y=Mx+b and M=slope and b=y value of x intercept
so y=-4x+7
The ratio from blueprints to bedroom is
... (3 in) : (8 ft) = (1/4 ft) : (8 ft) = 1 : 32
The dilation factor from blueprint to bedroom is 32.
The answer is 157 because you do 12 x 16 which is the shaded region and the unshaded region and you get 192. Then you do 7 x 5 which is not the shaded region and it equals 35.Now you do 157-35 and then you get 157
HI THERE!
i can help you :)
------------------------------------------------------------------------------------------------------------------
let the number of raisins (in pounds) be R and the number of peanuts (in pounds be p.
since the bag is 30 pounds, so R+P =30
the total cost of the bag is 30 pounds* 4.05 per pound = $121.50 .
now we can use the per-pound costs to write an equation . . .
5R+3.8P=121.5
Now just solve that first equation. . (R+P=30) for R. R= 30- P
now use that to substitute in the other equation
5R+3.8P=121.5
5(30-p) + 3.8P=121.5
solve for p
150- 5P+ 3.8p = 121.5
150-1.2p=121.5
150-1.2p=121.5
-1.2p=-28.5
P=23.75
now use that to find r
R+p =30
r+23.75=30
R=6.25
(hope this helps sorry it took so long to type )
have a good day !
