Answer:
5 adults went on the trip.
Step-by-step explanation:
There are 14 children ($75 each) and the total was $1475. We need to find out how many adults were there ($85 each)
c is for children and a is for adults
equation: $75c+ $85a = $1475
$75(14)+ $85a= $1475
$1050 + $85a = $1475
-1050 -1050
$85a = $425
85a/85 = 425/85
a = 5
5 adults went on the trip. Hope this helps! :)

What is unitary method ?Unitary method is finding the value for a single unit.
According to the given question During spring break, a class of 14 children went to Walt Disney World in Florida the price for each child’s ticket was 75 dollars.
So, Cost of tickets of 14 children is
= (14 × 75) dollars.
= 1050 dollars.
Total amount spent on tickets for children and adults is 1475 dollars.
∴ Total amount spent for tickets for the adults is
= ( 1475 - 1050 ) dollars.
= 425 dollars.
Given price of one ticket for adult is 85 dollars, So for 425 dollars the no. of tickets will be
= 425/85 dollars.
= 5 tickets which states there were 5 adults.

Answer:
No, this is not a function.
Step-by-step explanation:
This is not a function because not every input goes to exactly one output. In this example, 2 is listed twice. 2 goes to both 4 and 8. Because of this, it is not a function.
Bill rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 82 cents for each mile driven. Bill had to pay$222.77 when he returned the truck. For how many miles did he drive the truck?
Answer:
251 miles
Step-by-step explanation:
To answer this, we first must subtract the total Bill ended up paying by the base fee:
222.77 - 16.95 = 205.82
Now, we divide this total by 82 cents:
205.82 / 0.82 = 251
So, Bill drove the truck 251 miles

Answer:
5. a. Consecutive interior angles.These types of angles are supplementary.
b. x + 75 +x +125 = 180
=> 2x = 180–200
=> 2x = –20
=> x = –20/2
=> x = –10
Bonus question:-
angle 1 = 48°
angle 2 = 180° –78°
= 102°
value of f :-
f + 48 + 102 = 180
=> f + 150 = 180
=> f = 180–150
=> f = 30°
Solve. X^2+8x=9
a. What number should be added to both sides of the equation to complete the square?
b. Solve for x by completing the square

Suppose a basketball player has made 291 out of 389 free throws. If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50. Step 1 of 2 : Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
The expected value of the proposition is -$0.76.
Step-by-step explanation:
It is provided that a basketball player has made 291 out of 389 free throws.
Then rate of him making a free throw is,
[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]
The probability that he makes the next 2 free throws is:
[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]
The payout rules are:
If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50.Compute the expected value of the proposition as follows:
Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)
[tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]
Thus, the expected value of the proposition is -$0.76.
A soccer ball is punted in the air. Its height after x seconds can be modeled by a quadratic function. The soccer ball reaches its maximum height of 85 feet after 3 seconds. The ball is trapped at a height of 2.5 feet, 6 seconds after being kicked. Write a quadratic function that models the height of the soccer ball, x seconds after being kicked.
Answer:
[tex]-9.31x^2+56.26x[/tex]
Step-by-step explanation:
Let the quadratic function be:
[tex]h=ax^2+bx+c[/tex]
Where [tex]h[/tex] is the height of soccer ball and
[tex]x[/tex] is the time in seconds.
Initially, at time [tex]x=0\Rightarrow h=0[/tex]
Therefore, [tex]c=0[/tex]
Given that,
[tex]x=3, h=85\\and\\x=6, h=2.5[/tex]
Putting the values and making equations in [tex]a,b[/tex] :
[tex]85=9a+3b\\2.5=36a+6b[/tex]
By solving the above equations, we get:
[tex]a=-9.31\\ and\\b =56.26[/tex]
So, the quadratic expression is:
[tex]-9.31x^2+56.26x[/tex]
You are renting a beach house for the summer. The cost of renting the beach house plus the one-time security deposit is represented by the equation y = 151x + 575 , where represents the number of days that the beach house is rented and y is the total cost of the rental. What is the cost of the security deposit ?
Answer:
The security cost is 575
Step-by-step explanation:
Given
[tex]y = 151x + 575[/tex]
x = days
y = cost
Required
Determine the security deposit
From the equation, we understand that
x represent days:
This implies that
151x represent the payment for x days.
So, the security cost is 575
(48,-30) (61,-45) (74,-60) find the y intercept
Answer:
The y-intercept is about 25.385
Step-by-step explanation:
Calculate slope from difference in y-values divided by difference in x-values.
-15/13 is slope.
Use slope-intercept form.
Y= mx + b
Substitute values from given coordinates for y and x, then solve for b
-60 = -15/13(74) + b
-60 = -85.385 + b
-60 +85.385 = b
25.385 = b

what is the slope if a line passes through the points (28,86) and (34,83)
Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.
There are 72 eight grade students and 84 sixth grade students participating in the Fun Run competition. The students will be put into groups among their own grade and into the largest possible equal groups with no students left over. How many students will be in each group? Group of answer choices
Answer:
12 students
Step-by-step explanation:
Given that:
Eighth grade student = 72
Sixth grade student = 84
To group the students into the largest possible equal group with no student left, obtain the greatest common factor of the number of sixth grade and eighth grade student
Factors of 72:
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36
84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 81
The greatest factor common in both numbers is 12.

yes
Step-by-step explanation:
y < 5x - 4
1 < 5(1) - 4
1 < 1
This is not a true statement. 1 cannot be less than 1 itself so the answer is no.
7x - 4 < 28

Answer: [tex]3 \le x \le 5[/tex]
x is any real number between 3 and 5, including both endpoints
================================================
Explanation:
If A < B, then 1/A > 1/B. Applying the reciprocal flips the inequality sign.
For example, if 2 < 3, then 1/2 > 1/3. It might help to look at the decimal representations
1/2 = 0.500
1/3 = 0.333
We see that 1/2 is larger.

The inequality [tex]x < y < z[/tex] is the same as [tex]x < y \ \text{ and } \ y < z[/tex].
We've broken the single inequality into two smaller parts.
The given inequality breaks down into [tex]\frac{1}{6} \le \frac{1}{x+1}[/tex] and [tex]\frac{1}{x+1} \le \frac{1}{4}[/tex]
------------
Let's solve the first inequality for x
[tex]\frac{1}{6} \le \frac{1}{x+1}\\\\6 \ge x+1\\\\6-1 \ge x\\\\5 \ge x\\\\x \le 5[/tex]
Repeat for the other inequality as well
[tex]\frac{1}{x+1} \le \frac{1}{4}\\\\x+1 \ge 4\\\\x \ge 4-1\\\\x \ge 3\\\\[/tex]
-------------------------
We found that [tex]x \ge 3 \ \text{ and } \ x \le 5[/tex]
This is the same as [tex]3 \le x \ \text{ and } \ x \le 5[/tex] which combines to [tex]3 \le x \le 5[/tex]

identify the slope of the represented by the equation below. y=-1 / 4 x + 7
y=-3X+5
Answer:
M=-1/4
Step-by-step explanation:
Use the slope intercept form y=mx+b to find the slope m.
Answer:
The slope of the equation: y=-1/4x+7 is -1/4
The slope of the equation: y=-3x+5 is -3
Step-by-step explanation:
It is easier to think of the slope at the number behind the x variable. But algebraically, y=mx+b is the formula and the number that is in the value of m is the slope of the linear function.
