At the most recent dance ASB sold 143 tickets and collected $1470 of students sold for $10.00 and teachers tickets sold for $15.00 how many teachers attended the dance
Answer:
8
Step-by-step explanation:
1470 = 10s+15t
143 = s+t
1470 = 10(143-t)+15t
40 = 5t
8 = t
Which mapping(s) below represent(s) a function?
Answer: D
Step-by-step explanation:
Factor the polynomial: x^7 - x^5
Select one:
a. x^5(1 - x)
b. x^5(1 - 2x)
c. x^5(x^2 - 2x)
d. x^5(x^2 - 1)
Answer:
d. x^5(x^2 - 1)
Step-by-step explanation:
x^7 - x^5
Factor out x^5
x^5(x^2−1)
Consider x^2−1. Rewrite x^2−1 as x^2−1^2. The difference of squares can be factored using the rule: a^2 - b^2 =(a−b)(a+b).
(x−1)(x+1)
Rewrite the complete factored expression.
x^5(x−1)(x+1)
Simplify.
(x^2 - 1)x^5
Swap terms to the left side.
x^5(x^2 - 1)
Answer: D. [tex]x^{5} (x^{2} -1)[/tex]
Step-by-step explanation:
x^5 (x^2-1)
x^5 (x^2-1^2)
x^5 (x+1)(x-1)

find the solution to the system of equations
Solve the following equation algebraically:
-16 = 16x?
How many solutions does this equation have? Explain.
a. -1 = x3; One solution because only -1 will satisfy the equation.
b. -1 = x2; No real solution because there is no real number that, when squared, produces -1.
c. 1= x?: Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1=-x?: One solution because only -1 will satisfy the equation.

Find AC please, help is very much appreciated.
Answer:
AC ≈ 67.9
Step-by-step explanation:
15² = 9 (3x + 1 + 9)
225 = 9 (3x + 10)
225 = 27x + 90
135 = 27x
x ≈ 19.29
AC = (3x + 1 + 9)
AC = 3 (19.2857...) + 1 + 9
AC = 57.857... + 1 + 9
AC = 57.857... + 10
AC ≈ 67.9
Find the length of the missing side.
Answer: i think 80 not sure tho i failed my last test
Step-by-step explanation:
Answer:
80 in
Step-by-step explanation:
Because this is a right triangle we can find the length of the missing side using the Pythagorean Theorem
Given the hypotenuse and one leg we do
[tex]c^2-b^2=a^2[/tex]
where c = hypotenuse and b = leg
[tex]82^2=6724\\18^2=324\\6724-324=6400\\\sqrt{6400} =80[/tex]
so we can conclude that the missing side length is equal to 80
finding angle measures with trig. Find the missing angle measures. Round to the nearest whole number
Answer:
let angle be x
Step-by-step explanation:
relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=13/26
x=sin-¹(13/26)=30°
2.relationship between perpendicular and base is given by tan angle
tan x =p/b
tan x =7/16
x=tan -¹(7/16)=23.63°
3.relationship between between perpendicular and base is given by tan angle
tan x =p/b
tanx=31/50
x=tan-¹(31/50)=31.8°
4.relationship between base and hypotenuse is given by cos angle
cos x =b/h
cos x=5/7
x=cos-1(5/7)=44.4°
5.relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=4/14
x=sin-¹(4/14)=16.6
6..relationship between base and hypotenuse is given by cos angle
cos x=6/7
x=cos-¹(6/7)=31.0027
7.relationship between perpendicular and base is given by tan angle
.tanx=29/37
x=tan-¹(29/37)=38.09
8.relationship between perpendicular and hypotenuse is given by sin angle
.sin x=43/60
x=sin-¹(43/60)=45.78
9..relationship between base and hypotenuse is given by cos angle
cos x=32/44
x=cos-¹(32/44)=43.34
