The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.
Answers
Answer:
3s + c = 38 3s + 2c = 52
Step-by-step explanation:
Answer: Senior Citizen Ticket = $8, Child Ticket = $12
Step-by-step explanation:
Let's use S for senior tickets, C for child tickets.
3S + 1C = 38
3S + 2C = 52
Find C in terms of S with the first equation:
C = 38 - 3S
Now substitute the above equation for C in our second equation to find S.
3S + 2(38 - 3S) = 52
3S + 76 - 6S = 52
-3S = -24
S = 8
Now plug this value for S back into the first equation:
3(8) + C = 38
C = 12
So S = $8 and C = $12

She now has $3567.91 in the account. How much money did she start the account with?
Answers
Answer: [tex]\$2297.47[/tex]
Step-by-step explanation:
Given
Rate of interest [tex]r=4.5\%[/tex]
time period [tex]t=10\ year[/tex]
Amount [tex]A=\$3567.91[/tex]
Amount in compound interest is given by
[tex]\Rightarrow A=P[1+r\%]^t[/tex]
where, [tex]P=\text{Principal}[/tex]
Insert the values
[tex]\Rightarrow 3567.91=P[1+0.045]^{10}\\\\\Rightarrow P=\dfrac{3567.91}{1.5529}\\\\\Rightarrow P=\$2297.47[/tex]

Which answer represents the series in sigma notation? −7+(−2)+3+8+13 ∑j=15(5j−12) ∑j=15(−8j+1) ∑j=15−5(15)j−1 ∑j=155j−1
Answers
Answer:
∑j=15(5j−12)
Step-by-step explanation:
For j = 1 up to j = 5
j = 1
(5j - 12) = (5(1) - 12) = 5 - 12 = - 7
j = 2
(5j - 12) = (5(2) - 12) = 10 - 12 = - 2
j = 3
(5j - 12) = (5(3) - 12) = 15 - 12 = 3
j = 4
(5j - 12) = (5(4) - 12) = 20 - 12 = 8
j = 5
(5j - 12) = (5(5) - 12) = 25 - 12 = 13
(-7 + (-2) + 3 + 8 + 13)

D
[tex]2 \ \frac{1}{4} [/tex]
Answers
Answer:
D. 2 1/4
Step-by-step explanation:
3/4 inch = 8 feet
24 divided by 8 = 3
(meaning you would multiply eight three times in order to get to 24)
So....
3/4 x 3 = 2 1/4
Answer: 2 1/4
Hope this helps :)
Answer: D - 2 1/4”
Step-by-step explanation:
8 feet goes into 24 feet 3 times
Eg. 24/8 = 3
If 3/4” = 8 feet, then 3 x 3/4” = 24 feet
3 x 3/4” = 2 1/4”

Answers
Answer:
12
Step-by-step explanation:
First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.
Sin 53 degrees = opposite side / hypotenuse side.
The opposite side is x and the hypotenuse side equals 15.
sin53= x/15
15 ( sin 53 ) =x
x= 11.97953
Round
x=12

Carmella likes to hike for more than 4 hours but less than 6 hours. She hikes at a speed of 2 miles per hour.
If m is the number of miles Carmella likes to hike, which inequality is true?
A. 0.33
B 2.0
C 4.0
D 6.0
E 8.0
Answers
Answer:
Guys the answer is E. I just took the test.
Step-by-step explanation:
Short answer: Look at the inequalities and plug in either 10 or 8 for m and then you're all set :)
Long Answer:So what you should do first is calculate how long she hikes for and how many mph. It says that she likes the hike for more than 4 hours but less than six. She also hikes at least 2 mph. So if you were ever in first grade you would know that she hikes for at least 5 hours. Now 5 x 2 is 10. Now you can either plug 8.0 into the inequalities or 10 but either way its going to be more than whatever number is first in the inequality but less than 12.

One number is 2 more than another number. If the product of the two numbers is 35, what are the numbers? Please show the work
Answers
Answer: 5 and 7.
Step-by-step explanation: I’m sorry I don’t know what kind of equation to do but I’ll show how I got the answer if that’s what you mean.
First I made a list of numbers that when multiplied equal 35
Then I went through the list and took out all the options that were not one number being 2 more than the other.
The only option left is 5 x 7 (5*7)
what kind of equation do you want? Like 5*7 = 35 and 5 + 2 = 7?
The numbers are 5 and 7.
What is equation?A mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
let the first number be 'x'
another number = x+2
According to question,
x(x+2)= 35
x²+2x-35=0
x²+7x-5x-35=0
x(x+7)-5(x+7)=0
(x-5)(x+7)=0
x= +5, -7
Hence, the numbers are 5 (x) and 7 (x+2).
