Answer:
Step-by-step explanation:
I imagine you are in the section in math that teaches about systems! We need a system here to solve this problem...meaning we have 2 unknowns and we need to write 2 equations to solve for them. The first equation will involve the NUMBER of tickets sold, while the second equation will involve the COST of the tickets. These are 2 very different things, and we have what we need to write each equation. First the number of tickets equation:
We know that the number of student tickets (s) and the number of non-student tickets (n) totaled 15 tickets. That means the numbers equation is
s + n = 15
Now onto the money. Since s is student tickets, and each student ticket cost 12.50, the expression for that is 12.5s; since n is non-student tickets and each non-student ticket cost 18.50, the expression for that is 18.5n. That is the money expression for each type of ticket, and we know that the sales of these tickets totaled 223.50; therefore, the money equation is
12.5s + 18.5n = 223.5 (notice I dropped off the 0's since we don't need them).
Go back to the first equation and solve it for either s or n. I solve is for s:
If s + n = 15, then
s = 15 - n. Sub that into the second equation in place of s now:
12.5(15 - n) + 18.5n = 223.5 and simplify a bit by distributing to get
187.5 - 12.5n + 18.5n = 223.5 and combine like terms to get
6n = 36 so
n = 6. That means that there were 6 non-student tickets sold and
s + 6 = 15 student tickets sold:
s = 15 - 6 so
s = 9

A florist used 14 flowers to make a bouquet including 6 daisies what is the probability that a randomly selected flower will be a daisy
Answer:
3/7(when simplified)
Step-by-step explanation:
there are 6 daisies out of 14 flowers and so the probability would be 6/14. When simplified, the answer would be 3/7
What is the value of u?
u+40°
U-19°
U=
Answer:
u = 59
Step-by-step explanation:
The sum of the exterior angle is equal to the sum of the opposite interior angles
u+ u-19 = u+40
2u -19 = u+40
Subtract u from each side
2u-19-u = u+40-u
u-19 = 40
Add 19 to each side
u+19-19 =40+19
u = 59
Find the value of x that makes:
Answer:
correct value of x = 5
Step-by-step explanation:
[tex] \frac{ {( - 2)}^{4x + 2} }{ {( - 2)}^{2x} } = {( - 2)}^{12} \\ = \frac{ {( - 2)}^{4 \times 5 + 2} }{ { ( - 2)}^{2 \times 5 } } \\ = \frac{ {( - 2)}^{22} }{ { ( - 2)}^{10} } \\ = \frac{4194304}{1024} \\ = 4096 = 4096(i.e \: {( - 12)}^{12} = 4096) \\ [/tex]

Find x.
[tex] \frac{x}{x + 7} = \frac{16}{22} [/tex]
The equals is for proportionate I couldn't find the symbol for it.
According to the property of proportions,
Product of means = Product of extremes
x and 22 are extremes. (x + 7) and 16 are means.So, simply we did cross multiplication.

someone help me find what is m
Answer:
measure of angle F= 109 degrees
Step-by-step explanation:
I believe by m you are solving for angle F. So, angle H =71 degrees. GF and HI are parallel. In order to find angle G, Take the supplementary of 71 degrees, so 180-71 = angle G =109 degrees. Because GH and FI are congruent, the angles should be same across the shape, so angle I 71 degrees. Quadrilateral has a total of 360 degrees, so, 360-71-109-71=109 degrees. In general, angke G would equal angle F because of the trapezoid properties that take place when both bases are parallel and two of the sides are congruent, the trapezoid is an isosceles trapezoid

Step-by-step explanation:
Your house had a value of $480,000 and increased in value by 3.5%. How much is your house worth now?
Answer:
$496,800
Step-by-step explanation:
Present cost = $480,000
%increase = 3.5%
Present price of the house = 480,000 + 3.5% of 480,000
= 480,000 + 0.035 * 480,000
= 480,000 + 16,800
= $496,800
Present price of the house = $496,800
What is area? how is the mass of a body? Write its si unit.
Answer:
The total quantity of matter contained in an object is called its mass.
It is scalar quantity.
It is measured by beam balance.
Mass of the object remains constant at all the places.
We can measure mass of an object by its inertia.
SI unit of mass is ”kg”.

Find the common difference for an arithmetic series with
a1=5 and S10 = 320.
Answer:
6
Step-by-step explanation:
Let [tex]n = a_{10}[/tex]. We know the formula for the sum of an arithmetic sequence is:
[tex]S_{n} = \frac{n(a_{1}+a_{n} )}{2}[/tex]
Where n is the number term you are finding the sum up to, a1 is the first term, and an is the nth term. We can substitute what we have:
[tex]320=\frac{10(5 + n)}{2}[/tex]
[tex]640=10(n+5)\\64=n+5\\n=59[/tex]
The formula to find the nth term of an arithmetic series is:
[tex]a_{n} = a_{1} + (n-1)d[/tex]
Where d is the common difference. Again, we can plug in what we have;
[tex]59 = 5 + 9d\\9d = 54\\d = 6[/tex]

The yearbook has 12 pages for ads. Each page measures 6 in. By 12 in. Each ad measures 6 in. By 3 in. If all the ad space sells at $10 per ad, how much money will this raise for the yearbook?
Answer:
$480
Step-by-step explanation:
Each page measures 6 in. By 12 in. Each ad measures 6 in. By 3 in
based on the dimensions, there would be 4 ads per page
total ads in 12 pages = 4 x 12 = 48
total cost of ads = 48 x 10 = 480

You select a marble without looking and then put it back. If you do this 12 times, what is the best prediction possible for the number of times you will pick a pink marble? there are 3 pink marbles
Answer:
6 times
Step-by-step explanation:
If there are total of 6 marbles and 3 are pink, then you will have a one half (or 50%) chance of picking a pink marble. Because you put the marble back each time, your chance of picking a pink marble remains the same every time.
So one half of 12 is 6. You are predicted to pick a pink marble 6/12 times.
I dont get this. please help
Answer:
Step-by-step explanation:
All of these are done exactly the same way so I will work out one of them for you, and you can follow my example to get the answers to the rest of them. I will do #5. The formula for this is
7(7 + x) = 8(8 + 13) and then solve the equation to find x:
49 + 7x = 168 and
7x = 119 so
x = 17.
Follow that pattern for each of your problems and you should be fine.
