Answer:
25 adult tickets were sold and 100 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be x and the number of student tickets sold be y.
We know that the total amount collected from the tickets was $850, and that a total of 125 tickets were sold. We can use this information to come up with two equations.
10x + 6y = 850 - Equation 1
x + y = 125 - Equation 2
Then, use the substitution method to solve for either x or y first, followed by the other.
From equation two:
x + y = 125
x = 125 - y - Equation 3
Sub eqn 3 into eqn 1:
10(125-y) + 6y = 850
1250 - 10y + 6y = 850
1250 - 4y = 850
-4y = - 400
y - 100
Sub y = 100 into eqn 2:
x + 100 = 125
x = 25
Check:
10(25) + 6(100) = 850

What is the measure of ZZYW in rhombus WXYZ?
779
w
Z
O A 38.5
OB 51.5
D103
Answer:
A. 38.5
Step-by-step explanation:
Since the angles <XWZ and <XYZ are congruent, <ZYW is just half of <XYZ, so you would just divide 77 in half to get your answer. It's a rhombus, so it works similarly to a square. If one side is congruent, the other is too.

Michael left home at 1400 and arrived at his uncle’s home at 1830. What will be the
average speed of his journey if he travelled 108 km?
Step-by-step explanation:
Michael's Journey Time = 4 hours and 30 mins
=
[tex]4.5hours[/tex]
Speed = Distance ÷ Time
Given Distance = 108km
Time = 4.5 hours
Speed =
[tex] \frac{distance}{time} \\ = \frac{108}{4.5} \\ = 24 \frac{km}{h} [/tex]
My bad the answer is
Answer: 24 kilometers per hour

You are considering buying organic milk at the grocery store. A gallon of organic milk costs $1.00 more than a regular gallon of milk. Write an equation to represent the additional cost (C) of buying a gallon of organic mik over time (t) where x represents the cost of a gallon of regular milk
Answer:
C= $1t + x
Step-by-step explanation:
So, an organic gallon of milk is 1 dollar more then regular so the equation starts at $1 + x.
But then buying the organic milk over time is t so you add that to the one dollar since it applies to the organic milk. Now the equation is $1t + x.
But now, the expression we wrote is equal to C so, now the equation is C=$1t + x

A. B = 55° or B = 125°
B. B = 67° or B = 102.2°
C. B = 62.4° or B = 117.6°
D. B = 59.6° or B = 120.40
Answer: option D. B = 59.6° or B' = 120.4°
Step-by-step explanation:
Since the law is a/sinA = b/sinB = c/sinC you can try and verify each of them, by
10/sin(B)=......
and only B = 59.6° or B' = 120.4° give you the closed to 8.2/sin(45)= 11.59655121 which was 11.59401915.
(why the closed? because the question said it is "approximated")
The values of angles B and B' will be 59.6° and 120.4°, i.e. option C is the correct answer.
What is triangle ?Triangle is a three sides two dimensional surface having three angles.
We have,
A triangle in which,
One of the angle is 45°, and the side opposite to angle 45° is 8.2 with corresponding angle B.
And the side opposite to angle B is 10.
Now,
Using the law of sine,
i.e.
[tex]\frac{SinA}{a} =\frac{SinB}{b} =\frac{Sin c}{c}[/tex]
So,
According to the given triangle,
We get,
[tex]\frac{Sin 45^0}{8.2} = \frac{Sin B}{10}[/tex]
We get,
[tex]Sin B=\frac{Sin 45^0}{8.2} *10[/tex]
On solving we get,
⇒
[tex]SinB= 59.58^0\ \ or\ \ SinB= 120.42[/tex]
i.e.
[tex]SinB= 59.6^0 \ \ or\ \ SinB'= 120.40[/tex]
So,
The option C is the correct answer.
Hence, we can say that the values of angles B and B' will be 59.6° and 120.4°, i.e. option C is the correct answer.

Dr. Garica is twice as old as his son. Twenty years ago he was 4 times as old as his son was then. How old are they now?
Answer:
Let's let g = Dr. Garcia's age and s = his son's age.
g = 2s, right?
20 years ago, Dr. Garcia was g - 20 years old. He was also 4(s - 20), 4 times his son's age 7 years ago.
g - 20 = 4(s - 20)
g - 20 = 4s - 80
In the first equation, we have g = 2s. We are going to substitute this g into the second equation.
2s - 20 = 4s - 80
60 = 2s
s = 30
So, his son is 30 and Mr. Garcia is 60. 30 x 2 = 60.
20 years ago, his son would have been 10 and Mr. Garcia would have been 40. 10 x 4 = 40.
Step-by-step explanation:
Brainliest?
Answer:
Dr. Garcia's age is 60, and his son's age is 30.
Step-by-step explanation:
Let x be Dr. Garcia's age, and y his son's age.
1. Dr. Garcia is twice as old as his son
x = 2 y
2. Twenty years ago, he was 4 times as old as his son was then
x - 20 = 4 (y - 20)
Substitute x in 2 and solve for y:
2 y - 20 = 4 (y - 20)
2 y - 20 = 4 y - 80
- 20 = 2 y - 80
60 = 2 y
y = 30
Put y back into 1:
x = 2 (30)
x = 60
So Dr. Garcia's age is 60, and his son's age is 30.

16. Guests who rent kayaks at a campground must pay an insurance fee and are charged
for each hour they use the kayak. Last year, the total cost for a guest to rent a kayak for
x hours was modeled by the expression 6 + 8x.
This year, the campground doubled the cost per hour for renting a kayak but kept the
insurance fee the same.
Which expression models the total cost for a guest to rent a kayak for x hours at the
campground this year?
A. 12 + 8x
B. 6 + 16x
C. 6 + 4x
D. 3 + 8x
Answer:
B.
Step-by-step explanation:
I had this question on a test and got it right
The expression models that shows the total cost for a guest to rent a kayak for x hours is 6 + 16x.
What is the model about?Note that in the question:
Last year = 6 + 8x.
Looking at the equation one can see that the premium is = 6
kayaks is known to be charging at 8
So we have to double the value which is:
8 x 2 = 16
So therefore, the equation will be:
16x + 6
Therefore, The expression models that shows the total cost for a guest to rent a kayak for x hours is 6 + 16x.
