The piggy bank contains 16 dimes, 8 nickels, and 12 quarters. This morning you removed 3 dimes and 5 nickels.Which expression correctly shows the amount remaining in the piggy bank?
Answers
8•0.05= 0.40¢
12•0.25= 3.00$
1.60$+0.40¢+3.00$= 5.00$
3•0.10= 0.30¢
5•0.05= 0.25¢
0.30¢+0.25¢= 0.55¢
5.00$-0.55¢= 4.45$
4.45$ is left in the piggy bank.

1/4 cup butter/3/8 cup sugar = 1 cup butter/ x cup sugar
To solve this proportion, we need to use cross products, or the multiplication of the numerator of one fraction by the denominator of the other, and setting them equal to one another. If done properly, the resulting equation is:
1/4x= 3/8
Finally, we just need to divide both sides by 1/4, which is the coefficient of x, as we are trying to get x alone. Your final answer is
x=1.5.
Therefore, this means that if Izzy uses 1 cup of butter, she would use 1 1/2 cups of sugar.

Answer:
67% or 0.67
Step-by-step explanation:
Given that:
P(1 child under age 21) = 55%
P(2 children under age 21) = 22%
P(3 children under age 21) = 15%
P(4 children under age 21) = 5%
P(5 or more children under age 21) = 3%
If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?
P(1 or 3 children under age 21):
Either the selected family has 1 child under 21 years of age OR the selected family has 3 children under 21 years of age ;
P(1 child under age 21) + P(3 children under age 21)
= 55% + 15%
= 67% = 0.67

Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.
We need to check the sum of 104+34+228+877:
104 + 34 + 228 + 877 = 1243
Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4
Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = 1
Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = 1
Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of 104 + 34 + 228 + 877 is really 1243.

Answer:
see explanation
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are congruent, then
CA = NE , that is
4x + 3 = 11 ( subtract 3 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
----------------------------------------
AR = EW, that is
4y - 12 = 10 ( add 12 to both sides )
4y = 22 ( divide both sides by 4 )
y = 5.5

NW = x + y = 2 + 5.5 = 7.5

Answer:
x = 8
Step-by-step explanation:
Okay, so the top and bottom of a parallelogram are equal (or else it would be a trapezoid), so we just have to construct our cute lil algebraic expression:
x + 5 = 13
So now we have to do the inverse operations thingy:
13 - 5 = 8
So x = 8
