Answer: I believe this is correct, i got 80 tickets
Step-by-step explanation:
I divided 2212.50 by the adult tickets, 7.50, and got 295. if the adults sold 295 tickets, then the students would have sold 80, because thats all that were left. I hope I helped
The number of student tickets the class sold is 200.
Let
x = number of student ticket sold
y = number of adult ticket sold
The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. Therefore,
Total tickets:x + y = 375The junior class collected $2,212.50 in ticket sales. Therefore,
Total sold:4.50x + 7.50y = 2212.50Combine the equation to get the number of student ticket sales.
x + y = 375
4.50x + 7.50y = 2212.50
Multiply equation(i) by 4.50x
4.50x + 4.50y = 1687.5
4.50x + 7.50y = 2212.50
3y = 525
y = 525 / 3
y = 175
x + y = 375
x = 375 - 175
x = 200

What is wrong with this equation 7/9-8/9=1/9
Answer:
the answer would be -1/9
because you're subtracting 8/9 from 7/9, not the other way around.
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
7/9-8/9=1/9
We have a common denominator
( 7-8) 1
--------- = ----
9 9
7 -8 is equal to -1 not 1
The answer should be -1/9 not 1/9
Write an expression for the sequence of operations described below.
add 3 to 6, then multiply the result by 5
Type x if you want to use a multiplication sign. Do not simplify any part of the expression.
help me por favor
Answer: (3+6)x5
Step-by-step explanation: It wants you to add first so put parentheses around 3+6 and then multiply by 5.
The expression for the sequence of operations would be; (3 + 6 ) x 5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol.
Given that the phrase "add 3 to 6, then multiply the result by 5"
Then first add 3 and 6 = 3 + 6
To indicate the multiplication sign we will use x.
Now multiply the result by 5;
(3 + 6 ) x 5
Hence, the expression for the sequence of operations would be; (3 + 6 ) x 5.

The dot plot shows predictions for the winning time in the 200-meter sprint. The winner finished the race in 22.3 seconds. What is the greatest percent error among the predictions?
Answer:
3.2%
Step-by-step explanation:
The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).
Step-by-step explanation:Given that,
The dot plot shows predictions for the winning time in the 200-meter sprint.
The winner finished the race in 22.5 seconds.
We have to determine,
What is the greatest percent error among the predictions.
According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds.
Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)
Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).
Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

question:
1. Use the Pythagorean theorem to find AD.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
SHOW YOUR WORK
Problem 1
Answer: AD = 9
-------------------------------------------------
Work Shown:
Focus on triangle ADB, which is the smaller triangle on the left.
We have these side lengths
AD = unknown leg
BD = 12 = known leg
AB = 15 = known hypotenuse
Let's apply the Pythagorean Theorem to find the unknown leg
a^2 + b^2 = c^2
(AD)^2 + (BD)^2 = (AB)^2
(AD)^2 + (12)^2 = (15)^2
(AD)^2 + 144 = 225
(AD)^2 = 225-144
(AD)^2 = 81
AD = sqrt(81)
AD = 9
Side AD is 9 units long.
========================================================
Problem 2
Answer: AC = 25
-------------------------------------------------
Work Shown:
AC = AD + DC .... segment addition postulate
AC = 9 + 16 ..... substitution; refer to problem 1
AC = 25
========================================================
Problem 3
Answer: Triangle ABC is a right triangle.
-------------------------------------------------
Work Shown:
The Pythagorean Theorem Converse says "if a^2+b^2 = c^2 is a true equation, then the triangle with sides a,b,c is a right triangle". Keep in mind that c is always the longest side (hypotenuse). The order of 'a' and b doesn't matter. Convention has us usually do [tex]a \le b[/tex] but again the order isn't important.
We have these three sides
a = 15 (length of side AB; leg #1)b = 20 (length of BC; leg #2)c = 25 (length of AC; hypotenuse)Plug those values into the equation below. Simplify each side.
a^2+b^2 = c^2
15^2 + 20^2 = 25^2
225 + 400 = 625
625 = 625
We get a true equation. Therefore, triangle ABC is a right triangle.
Answer:
Step-by-step explanation:
Pythagorean = c^2 =a^2 + b^2
we are given c and a so solve for b
c^-a^2 = b^2
15^2- 12^ = b^2
81= b^2
[tex]\sqrt{81}[/tex]=b
9=b
AD=b
AC = AD + 16
AC =9 + 16 =25
if it's a right triangle then Pythagorean will work with the sides to make 25
AC^2 = 15^2+20^2
AC = [tex]\sqrt{625}[/tex]
AC = 25

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain
Answer:
If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.
Answer:no
Step-by-step explanation:
Because u can not subtract a denominator from numerator u must subtract the denominator by the denominator
