Answer:
26 CD's
Step-by-step explanation:
If the shelf is 9 3/4 inches long, and each CD is 3/8, all we have to do is divide. We get 26.
First:
Convert any mixed numbers to fractions.
Then your equation becomes:
39/4÷3/8
Applying the fractions formula for division,
=39×8/4×3
=312/12
Simplifying 312/12, the answer is
=26

9514 1404 393
Answer:
3 2/3
Step-by-step explanation:
The mean is the sum of the 6 numbers, divided by 6.
(8 + 1 + 2 + 6 + 1 + 4)/6 = 22/6 = 3 2/3
Garrett's coin bank contains 500 nickels,
dimes, and quarters. He has the same
number of nickels as dimes, and the total
value of the coins is $72.50. How many
quarters does he have?
Step-by-step explanation:
d = number of dimes
n = number of nickels
q = number of quarters
d + n + q = 500
d×$0.10 + n×$0.05 + q×$0.25 = $72.50
n = d
we are focusing now on one variable (let's try d), and we are transforming the other equations to express the other variable by this one variable.
since n = d we have already
d + d + q = 500
2d + q = 500
q = 500 - 2d
with that we go into the main equation
d×0.10 + d×0.05 + (500 - 2d)×0.25 = 72.50
d×0.15 + (500 - 2d)×0.25 = 72.50
d×0.15 + 500×0.25 - 2d×0.25 = 72.50
d×0.15 + 125 - d×0.50 = 72.50
-d×0.35 = -52.50
d = 52.50/0.35 = 150
n = d = 150
q = 500 - 2d = 500 - 2×150 = 500 - 300 = 200
so, he has 200 quarters.

what can you say about the unknowns in the equation x+22=y+32
Answer:
x = y + 10
y = x -10
Step-by-step explanation:
For x:
Given: x + 22 = y + 32
Subtract 22 from both sides: x = y + 32 - 22
Answer: x = y + 10
For y:
Given: x + 22 = y + 32
Subtract 32 from both sides: x + 22 - 32 = y
Answer: y = x -10

Which point on the density curve represents the median value?
Answer is B
Answer:
Graphically, the MEDIAN of a density curve is the equal-area point, the point with half the area under the curve to its left and the other half to its right. The quartiles divide the area under the curve into quarters.
Step-by-step explanation:
The median of a density curve is the equal-areas point: the point that divides the area under the curve in half. The mean of a density curve is the balance point, at which the curve would balance if it were made of solid material.

The cost of a cup of tea is t cents.
The cost of a cup of coffee is (t + 5) cents.
The total cost of 7 cups of tea and 11 cups of coffee is 2215 cents.
7
Find the cost of one cup of tea.
Step-by-step explanation:
The cost of a cup of tea is t cents.
The cost of a cup of coffee is (t + 5) cents.
The total cost of 7 cups of tea and 11 cups of coffee is 2215 cents.
Therefore,
7t+11t+55=2215
18t=2160
t=120

Answer
Using the probability concept, it is found that there is a 0.6087 = 60.87% probability of a puppy having no spots.
A probability is the number of desired outcomes divided by the number of total outcomes, that is:
[tex]p = \frac{D}{T}[/tex]
In this problem:
There are 6 + 8 + 4 + 5 = 23 puppies, thus [tex]T = 23[/tex].6 +8 = 14 have no spots, thus [tex]D = 14[/tex]Then, the probability is:
[tex]p = \frac{D}{T} = \frac{14}{23} = 0.6087[/tex]
0.6087 = 60.87% probability of a puppy having no spots.

Which pair of numbers are not opposites?
|7| and -7
17 and – 17
17 and | -17|
71 and - 71
Answer:
The answer is C, 17 and | -17|
Step-by-step explanation:
We can solve this using the process of elimination.
Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.
17 and -17 are opposites, since the opposite of a positive is a negative.
The last one is the same. 71 and -71 are opposites. That leaves us with C.
Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.

-7/3(12q+1/3r+6) someone help me I need it for something important
Answer:
Below
Step-by-step explanation:
-7/3 ( 12q + 1/3r + 6 )
multiply each number in the parentheses separately by - 7/3
- 7/3 ( 12q) = - 84/3 q or - 28q
- 7/3 ( 1/3r) = - 7/9 r
- 7/3 ( 6) = -42/3 or - 14
Putting back together you get
-28q - 7/9r - 14
Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x−1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposits his $350. Justify your reasoning.
Answer:
So the functions that are given are the following:
[tex]h(x)=350\\s(x)=(1.04)^{x-1}[/tex]
So in order to find the money in his account, there would have to be a substitution for (x=$350) in the first function, and a place in the second function.
