Answer:
[tex]a=85[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}5.10c+8.70a=1065.90\\c+a=149\end{case}[/tex], where [tex]c[/tex] represents the number of child tickets sold and [tex]a[/tex] represents the number of adult tickets sold.
Multiplying the second equation by [tex]-5.10[/tex] and adding both equations lets us isolate and solve for [tex]a[/tex]:
[tex]\begin{cases}5.10c+8.70a=1065.90\\-5.10c-5.10a=-759.9\end{case}\\3.6a=306,\\a=\fbox{$85$}[/tex].

Answer:
38) Angle 2 = 32°; angle 1 = 32°; angle 3 = 110°
39) Angle 3 = 81°; Angle 2 = 28°; angle 1 = 71°
Step-by-step explanation:
38) angle 2 = 180 - (110 + 38)
This is because sum of angles in a triangle is equal to 180°. Thus;
Angle 2 = 32°
Angle 1 = 38° due to the postulate that alternate interior angles are equal
Angle 3 = 110° due to corresponding angles postulate
39) Angle 3 = 81° due to the postulate that alternate interior angles are equal
Angle 2 = 28° due to the postulate that alternate interior angles are equal
Angle 1 = 180 - (81 + 28) = 71° due to the fact that angles in a triangle sum up to 180°

2x+y=-4
-3y=2x+12
Answer: 3y=12−2x 3 y = 12 - 2 x
Step-by-step explanation:
Answer:
Let
2x+y=-4——(1)
-3y=2x+12
2x+3y=-12—-(2)
Deduct eqt 1 from 2
(2x+3y=-12)
-(2x+y=-4)
2y=-8
y=-4
Put y=-4 into eqt 1
2x-4=-8
2x=-8+4
2x=-4
Divide both sides by 2
x=-2
:. x,y= -2,-4

Which of the following expresses the possible number of positive Icai
solutions for the polynomial equation shown below?
5x° + x2 - 7x+ 28 = 0
O A. Zero
B. One
C. Two or zero
D. Three or one
9514 1404 393
Answer:
C. Two or zero
Step-by-step explanation:
The signs of the polynomial terms are: + + - +.
There are two sign changes, one from + to -, and the other from - to +. The two sign changes means the number of positive real roots will be a maximum of 2. Any even number of roots may be complex, so will not be real. That is, the number of positive real roots may be 2 or 0.

(05.05) Which of the following inequalities matches the graph? (1 point)
Answer: Choice C. [tex]y \ge -1[/tex]
==========================================================
Explanation:
The boundary line is a solid line and it's horizontal. Every point on the boundary line has y coordinate -1. So y = -1 is the equation of the boundary line. We can write it as y = 0x-1.
The shading is above the boundary line, so the inequality is [tex]y \ge -1[/tex]
Any point (x,y) in the shaded region has y coordinate that is y = -1 or greater.
For example, the point (0,2) in the shaded region has y coordinate y = 2, and it satisfies the inequality [tex]y \ge -1[/tex] because [tex]2 \ge -1[/tex] is a true statement.
Note: the boundary line is solid, so any point on the boundary line is part of the shaded solution set. This is due to the "or equal to" as part of the inequality sign.

Answer:
f = 132 degrees
Step-by-step explanation:
The total angle measure of this is 360 degrees. We know 2 of the angles, so subtract them from 360 to get 198. The sum of f and g must equal 198 degrees. Since we know that f = 2g, we can divide 198 by 3 to get 66. So, we know g = 66. To find f, multiply 66 by two to get 132. So, g = 66 and f = 132

Who earns more per hour, and what is his or her pay rate?
Austin swam 1.4 laps each minute. Ashley is Austin's older sister. She trains in the same pool and can swim 9 laps in 6 minutes. Is Ashley a faster swimmer than Austin? Question - how can you use the unit rate in minutes per lap to compare Ashley's speed to Austin?
Answer: Asley is faster than Austin.
Step-by-step explanation:
Given: Austin swam 1.4 laps each minute.
Asley's sister can swim 9 laps in 6 minutes.
i.e. the number of laps she can swim in each minute = [tex]\dfrac96 = 1.5[/tex]
1.5 > 1.4, i.e. Asley swim more laps than Austin in a minute.
Hence, Asley is faster than Austin.
In mintues per lap, speed of Austin = [tex]\dfrac1{1.4}=0.71\text{ minute per lap}[/tex]
Speed of Ashley = [tex]\dfrac{6}{9}=0.67\text{ minute per lap}[/tex]
Ashley took lesser time then austin per lap.
Hence, Ashley is faster than Austin.

I’d just find the base and multiply but the lenght or height
SO in this case the base is 6*5/2 so 15
Now there 10 of those 15 in bases
SO multiply to find total
10*15=150
Now 150*2 becuase the bottome one is basically the same so that’d give you 300

Answer:
Function
Step-by-step explanation:
These coordinates do represent a function. For a relation to be a function every y-value must have an x-value, this means x's cannot repeat. In this relation x's never repeat, they simply increase by one every time. Therefore, this is a function.

Which of the following is a geometric series? 0.1 + 0.3 + 0.5 + 0.7 1 + 3 + 9 + 27 19 + 17 + 15 + 13 0.4 + 0.9 + 1.5 + 2.2
The series 1 + 3 + 9 + 27 is a geometric series because the common ratio is 3 option second is correct.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
As we know, the geometric series has a common ratio:
If a, b, c, d, e.....
is in the GP then,
b/a = c/b = d/c = and so on
We have a series:
0.1 + 0.3 + 0.5 + 0.7
0.3/0.1 ≠ 0.5/0.3
The above sequence is not a geometric series.
1 + 3 + 9 + 27
3/1 = 9/3 = 3
The above sequence is a geometric series.
19 + 17 + 15 + 13
17/19 ≠ 15/17
The above sequence is not a geometric series.
0.4 + 0.9 + 1.5 + 2.2
0.9/0.4 ≠ 1.5/0.9
The above sequence is not a geometric series.
Thus, the series 1 + 3 + 9 + 27 is a geometric series because the common ratio is 3 option second is correct.
