Shannon has 1 nickel, 2 dimes, and 5 unknown coins totaling $0.81. What kind of coins does Shannon have and how many are there of each denomination?
Answer:
The 5 unknown are 1 quarter, 3 dimes, and 1 penny.
Answer:
One penny
One nickel
Five dimes
One quarter total
Step-by-step explanation:
81 - 25(coins we know) = 56 cents left
So we know we need 1 penny
Then 4 coins make up 55 cents, so that's a quarter & 3 dimes
After a late night of studying, Ebony decides to grab a latte before class so she can stay awake through her morning lecture. She has only a one-dollar bill, a five-dollar bill, and a ten-dollar bill in her wallet. She pulls one out and looks at it, but then she puts it back. Distracted by a flyer for a new campus organization, she randomly hands a bill from her wallet to the clerk. Construct a sample space, and find the probability that (a)Both bills have the same value. (b)The second bill is smaller than the first bill. (c)The value of each of the two bills is even. (d)The value of exactly two of the bills is odd. (e)The sum of the values of both bills is less than . Write your answers in exact, simplified form.
Answer:
[tex]P(Same\ Bill) = \frac{1}{3}[/tex]
[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]
[tex]P(Both\ Even) = \frac{1}{9}[/tex]
[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]
[tex]P(Sum < 10) = \frac{1}{3}[/tex]
Step-by-step explanation:
Given
[tex]Bills: \$1, \$5, \$10[/tex]
[tex]Selection = 2\ bills[/tex]
The sample space is as follows:
This implies that we construct possible outcome that Ebony selects a bill, returns the bill and then select another.
This means that there are possibilities that the same bill is selected twice.
So, the sample space is as follows:
[tex]S = \{(1,1), (1,5), (1,10), (5,1), (5,5), (5,10), (10,1), (10,5), (10,10)\}[/tex]
[tex]n(S) = 9[/tex]
Solving (a): [tex]P(Same\ Bill)[/tex]
This means that the first and second bill selected are the same.
The outcome of this are:
[tex]Same = \{(1,1),(5,5),(10,10)\}[/tex]
[tex]n(Same\ Bill) = 3[/tex]
The probability is:
[tex]P(Same\ Bill) = \frac{n(Same\ Bill)}{n(S)}[/tex]
[tex]P(Same\ Bill) = \frac{3}{9}[/tex]
[tex]P(Same\ Bill) = \frac{1}{3}[/tex]
Solving (a): [tex]P(Second < First\ Bill)[/tex]
This means that the second bill selected is less than the first.
The outcome of this are:
[tex]Second < First = \{(1,5), (1,10), (5,10)\}[/tex]
[tex]n(Second < First) = 3[/tex]
The probability is:
[tex]P(Second<First\ Bill) = \frac{n(Second<First\ Bill)}{n(S)}[/tex]
[tex]P(Second<First\ Bill) = \frac{3}{9}[/tex]
[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]
Solving (c): [tex]P(Both\ Even)[/tex]
This means that the first and the second bill are even
The outcome of this are:
[tex]Both\ Even = \{(10,10)\}[/tex]
[tex]n(Both\ Even) = 1[/tex]
The probability is:
[tex]P(Both\ Even) = \frac{n(Both\ Even)}{n(S)}[/tex]
[tex]P(Both\ Even) = \frac{1}{9}[/tex]
Solving (e): [tex]P(Sum < 10)[/tex]
This question has missing details.
The correct question is to determine the probability that, the sum of both bills is less than 10
The outcome of this are:
[tex]One\ Odd = \{(1,10), (5,10), (10,1), (10,5)\}[/tex]
[tex]n(One\ Odd) = 4[/tex]
The probability is:
[tex]Pr(One\ Odd) = \frac{n(One\ Odd)}{n(S)}[/tex]
[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]
Solving (d): [tex]P(One\ Odd)[/tex]
This question has missing details.
The correct question is to determine the probability that, exactly one of the bills is 0dd
The outcome of this are:
[tex]Sum < 10 = \{(1,1), (1,5), (5,1)\}[/tex]
[tex]n(Sum < 10) = 3[/tex]
The probability is:
[tex]P(Sum < 10) = \frac{n(Sum < 10)}{n(S)}[/tex]
[tex]P(Sum < 10) = \frac{3}{9}[/tex]
[tex]P(Sum < 10) = \frac{1}{3}[/tex]
Based on the table, which function models this situation?
a. f(n) = -3n + 24
b. f(n) = -(1/3)n + 16
c. f(n) = -3n + 64
d. f(n) = -(1/3)n + 8
please show how you got the answer!
Answer:
A is correct. f(n) = -3n + 24
Step-by-step explanation:
We can see in the first two steps that two meals have been served, and six cups of pet food consumed. In other words, six cups are consumed in two meals, therefore three cups are consumed in each meal.
If we look at the remaining numbers on the chart, we can see that this carries through. This tells us that the correct answer must be either a or b, as "-3n" represents the consumption rate. If it were (1/3)n, then only a third of a cup would be consumed per meal.
Finally, we can figure out which of those two equations is correct simply by plugging a value pair into them. Starting with a:
f(1) = -3(1) + 24
= 24 - 3
= 21
correct.
To be certain, let's check with answer c:
f(1) = -3(1) + 64
= 64 - 3
= 61
incorrect.
So we can clearly say that the correct answer is "a". You can plug the other values into it to test that too:
f(3) = -3(3) + 24
= 24 - 9
= 15
correct
So we definitely have the right answer.

Problem 5) RS = 7Problem 6) x = 23.5=======================================
Explanations:
Problem 5) The equation to solve is (x+35)/2 = 21. This is because we average the two parallel bases x and 35, to get the length of the midsegment 21. You should end up with x = 7.Problem 6) Angles A and B are supplementary because of the same side interior angle theorem. It might help to extend out the parallel lines BC and AD. Also, extend out the transversal AB. Because the angles add to 180, the equation to solve is (5x-14)+(3x+6) = 180. It solves to x = 47/2 = 23.5find the reciprocal of each number 2/3, 1/7, 4 ( show work)
Answer:
A reciprocal is the fraction flipped around. So basically 3/2, 7/1, and 1/4. Since 4 is a whole number the denominator is 1. Therefore, the reciprocal is 1/4.

Answer:
(4) 750 < p < 1500
Step-by-step explanation:
The total cost for p people is ...
c = 750 +2.25p
The average cost per person is this total divided by the number of people:
c/p = (750 +2.25p)/p
c/p = (750/p) +2.25
Natasha wants this to be between 2.75 and 3.25:
2.75 < c/2 < 3.25
2.75 < 750/p +2.25 < 3.25 . . . . . . use the expression for c/p
0.50 < 750/p < 1.00 . . . . . . . . . . . subtract 2.25
We can split this to two inequalities to find the limits of p.
Left one
0.50 < 750/p
0.50p < 750 . . .multiply by p
p < 1500 . . . . . . multiply by 2
Right one
750/p < 1
750 < p . . . . . . multiply by p
These bounds on p can be summarized as ...
750 < p < 1500 . . . . matches choice (4)
_____
Additional comment
Once you realize that the fixed costs will be divided by the number of people attending, the maximum cost you want ($1 more than the per-person charge) will set the minimum number of people. To have the $750 fixed cost contribute only $1 to the cost per person, there must be at least 750 people to share that cost. The only answer choice with a 750 person minimum is (4).

The number of newspaper subscriptions currently sold in a city is 15,895. The
number of newspaper subscriptions has been decreasing at a rate of 12.8% per year.
What is the best prediction for the number of newspaper subscriptions the company
will have in 5 years? Round answer to a whole number. Only type the number in the
blank, nothing else.
Answer:
About 8014 subscriptions.
Step-by-step explanation:
We can write an exponential function to model the situation.
The standard form of an exponential function is given by:
[tex]f(x)=a(r)^x[/tex]
The current newspaper subscriptions is 15,895. So, a = 15895.
It has been decreasing at a rate of 12.8% each year.
In other words, the number of subscriptions next year will be 100% - 12.8% = 87.2% or 0.872 of the previous year. Thus, r = 0.872.
So, our function is:
[tex]f(x)=15895(0.872)^x[/tex]
Where x is the time that has passed in years.
So the number of newspaper subscriptions after five years will be:
[tex]f(5)=15895(0.872)^5\approx8014\text{ subscriptions}[/tex]

Answer:
(b) and (d)
Step-by-step explanation:
Given
See attachment for complete question
Required
Which group forms a rectangle of
[tex]Length = 15[/tex]
[tex]Width = 11[/tex]
First, calculate the area of the big rectangle
[tex]Area = Length * Width[/tex]
[tex]A_{Big} = 15 * 11[/tex]
[tex]A_{Big} = 165[/tex]
Next, calculate the area of each rectangle A to E.
[tex]A_A = 11 * 7[/tex]
[tex]A_A = 77[/tex]
[tex]A_B = 2 * 11[/tex]
[tex]A_B = 22[/tex]
[tex]A_C = 6 * 6[/tex]
[tex]A_C = 36[/tex]
[tex]A_D = 6 * 5[/tex]
[tex]A_D = 30[/tex]
[tex]A_E = 13 * 4[/tex]
[tex]A_E = 52[/tex]
Then consider each option.
(a) 3E + 2B
[tex]3E + 2B = 3 * 52 + 2 * 22[/tex]
[tex]3E + 2B = 156 + 44[/tex]
[tex]3E + 2B = 200[/tex]
(b) A + B + C + D
[tex]A + B + C + D = 77+22+36+30[/tex]
[tex]A + B + C + D = 165[/tex]
(c) 2C + 2D + 2B
[tex]2C + 2D + 2B = 2 * 36 + 2 * 30 + 2 * 22[/tex]
[tex]2C + 2D + 2B = 72 + 60 + 44[/tex]
[tex]2C + 2D + 2B = 176[/tex]
(d) A + 4B
[tex]A + 4B = 77 + 4 * 22[/tex]
[tex]A + 4B = 77 + 88[/tex]
[tex]A + 4B = 165[/tex]
(e) E + C + D + 3B
[tex]E + C + D + 3B = 52 + 36 + 30 + 3 * 22[/tex]
[tex]E + C + D + 3B = 52 + 36 + 30 + 66[/tex]
[tex]E + C + D + 3B = 184[/tex]
Recall that:
[tex]A_{Big} = 165[/tex]
Only options (b) and (d) match this value.
[tex]A + B + C + D = 165[/tex]
[tex]A + 4B = 165[/tex]
Hence, options (b) and (d) are correct

Bella has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $353.59.
She buys 3 bicycle reflectors for $4.98 each and a pair of bike gloves for $38.63.
She plans to spend some or all of the money she has left to buy new biking outfits for $49.20 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Bella can purchase while staying within her budget.
Step-by-step explanation:
$540 - $353.59 = $186.41
$186.41 - $4.98 = $181.43
$181.43 - $38.67 = $142.8
She has $142.8 left and if she want to buy the outfits for $49.20 she is going to have $93.6 left

On a cube, what proportion of the surface area is on each face, to the nearest percent?
Answer:
Cubes have 6 equal faces, and the surface area is the sum of all of these faces. Thus, one face would be 1/6 of the cube's surface area, or about 17%.
Step-by-step explanation:
The value of a angle
The sum of adjacent angles equals 180 degrees. Opposite angles are equal, so if you know the value of one angle, its opposite partner will have the same value. For example, if the value of one angle is 75 degrees its adjacent angle will be 105 degrees and its opposite angle will also be 75 degrees.
