Answer:
171
Step-by-step explanation:
Step 1: Let "x" and "y" be the variables
Let x = the number of adult tickets sold
Let y = the number of child tickets sold
Step 2: Add the variables and subtract the "x" variable
x + y = 486 y = 486 - x
Step 3: Add the given amounts by the variables next to it to equal the total
5.50x + 4y = 2416.50
5.50x + 4(486 - x) = 2416.50
5.50x + 1944 - 4x = 2416.50
Step 4: Subtracting the result from the number of tickets the booth sold
1.5x = 472.5
x = 315
y = 486 - 315 = 171
Therefore, there are 171 tickets of each type sold.
Convert 118 to radian measure.
Round your answer to the nearest hundredth.
Answer:
2.06 rad
Step-by-step explanation:
To change degree measure to radian measure
radians = degrees × [tex]\frac{\pi }{180}[/tex] , then
radians = 118 × [tex]\frac{\pi }{180}[/tex]
= [tex]\frac{118(\pi )}{180}[/tex] ≈ 2.06 rad ( to the nearest hundredth )
Answer:
2.06 radians to nearest hundredth.
Step-by-step explanation:
Radians = degrees * π/180
= 118 * π/180
= 0.6556π
= 2.0596.

Answer:
...
Step-by-step explanation:
1. B
angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)
2. 7x + 10 = 150 (since they are vertical angles)
7x = 140
x = 20
now plug in 7(20) +10
140+10=150
Is the triangle with the given side lengths a right triangle? EXPLAIN how you know.
3.9 mm, 8.0 mm, 8.9 mm
Answer:
It is a right triangle
Step-by-step explanation:
Use the Pythagorean theorem:
[tex]a^2+b^2=c^2\\\\3.9^2+8.0^2=8.9^2\\\\15.21+64=79.21\\\\79.21=79.21[/tex]
if they weren't equal, it wouldn't be a right triangle.
If 5% of the 300 students at NewzBrain Middle School were absent from school, how many of the students were in school?
Answer:
285 students were in school.
Step-by-step explanation:
5%=0.05
0.05*300=15
300-15=285
There were 285 students in school.
Given that 5% of the 300 students were absent, we can calculate it as follows:
= 5% of 300
= (5/100) x 300
= 0.05 x 300
= 15
Therefore, there were 15 students absent from school.
Now, the In school students
Total students - Absent students = In-school students
300 - 15 = 285
So, there were 285 students in school.

Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS,and 25 cents per off-peak time SMS.if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month, what will her monthly bill come to?
Answer:
Anita's monthly bill will be $164.25.
Step-by-step explanation:
Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:
100 + (0.85 x 45) + (0.25 x 105) = X
100 + 38.25 + 26.25 = X
138.25 + 26.25 = X
164.25 = X
Therefore, her monthly bill will be $ 164.25.

Use the distance formula to find the distance to the nearest tenth, from R17, -2) to W(-2, 3).
Answer:
17.7
Step-by-step explanation:
I'm assuming you meant R(17, -2) to W(-2, 3). Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5. Think of these as the legs of a right triangle. The distance between these points is the length of the hypotenuse of this triangle: d = √(5^2 + 17^2)
or √314, which, to the nearest tenth is 17.7.

Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.

Do mechanical waves travel faster or slower in more dense media?
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

6. Which expression is equivalent to 2(35 – 4) – (89 + 3)?
A. -2g - 1
B. -2g - 5
C. -2g - 7
D. -2g - 11
Answer:
Step-by-step explanation:
Following order of operations rules srequires that we do any work inside parentheses first. Thus, (35 - 4) = (31), and (89 + 3) = (92). Then:
2(35 – 4) – (89 + 3) = 2(31) - (92) = -60

What is the probability of rolling a pair of dice and not rolling the same number?
Answer:
5/6
Step-by-step explanation:
The "first" dice can land on any number, so there are 6 choices. The "second" can not be the same number as the first one. So there are 5 choices. We multiply to get 6*5=30 ways to roll a different number. There are 6*6 total ways so the probability is 30/36 which simplifies to 5/6.
