A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44

Step-by-step explanation:
A ghost crab can travel about 12 miles every 6 hours on the ocean’s floor. How far can the crab travel in 11 hours? Explain how you found your solution.
Answer:
22 miles in 11 hours!
Step-by-step explanation:
We already know a ghost crab can travel 12 miles in 6 hours.
Now, we just need to find the how many miles per hour the crab walks.
We simply divide 12 miles by 6 hours which gives us 2 miles in 1 hour.
That means, we multiply 11 by 2 which gives us 22 miles!
The ghost crab can travel 22 miles in 11 hours. When you find the rate of change by dividing 12 by 6, it gives you 2 m/h. That enables you to find the amount of miles by multiplying 11 hours by two which gives you 22!

Plz help with this question
since both equations are equal to y...
y = 2x + 10
y = -4x - 2
2x + 10 = y = -4x - 2
2x + 10 = -4x - 2
2x + (4x) = -2 + (-10)
6x = -12
x = -2
______________________________
plug in x = -2 into one of those equations: I will use y = 2x + 10
y = 2(-2) + 10
y = -4 + 10
y = 6
______________________________
okay, so I rechecked my answers several times, and I still got (-2,6)
That MC question has an error since none of the answer choices fit.
Inform your teacher about this.
(I'd say choose that (-3,4) since it works only for one equation y = 2x +10 .... maybe your teacher was supposed to use the other equation instead of y = -4x - 2)
Which model shows 1/4 divided by 3 ? A B C D
Answer:

Answer:
b or d
Step-by-step explanation:
Please please need help on this one
Answer:
Y=-6x
Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b
Y=-6x+0
Y=-6x
