Answer:
$52.5Step-by-step explanation:
Step one:
given data
we are given that the linear function for the cost is c=3.5t
c is the cost and
t is the number of tickets.
We are told that t=15, to find c, let us put the value of t in the linear function for the cost
[tex]c=3.5(15)\\\\c=52.5[/tex]
This shows that 15 tickets will cost $52.5
Write an equation in Slope Intercept Form for the following line.
Answer:
y=2x+-4
Step-by-step explanation:
Answer:
The equation in slope intercept form (y = mx + b) is y = 2x - 4
m = the slope
b = the y intercept
The line cross the y-axis at -4 so the y-intercept (b) is -4.
You can use the slope formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.
[tex]\frac{0--4}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2
So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

A firefighter climbed up to the middle of a ladder to see if there was any fire on the second floor of a building and there was none; he then climbed up 10 more steps and saw some smoke so he came back down 14 steps and waited for 5 seconds to check his equipment. He then climbed 20 steps all the way to the top of the ladder and got off on the roof. How many steps are there on the ladder?
Answer:
32
Step-by-step explanation:
Let there be n number of steps on the ladder.
First, the firefighter climbed up to the middle of a ladder. so to reach the middle of the ladder he must have climbed [tex]\frac n 2[/tex] steps.
Then, after climbed 10 more steps, the total number of stairs from the ground he climbed [tex]= \frac n 2 +10[/tex].
Then, he came back down 14 steps, so the total number of stairs from the ground he climbed [tex]= \frac n 2 +10 -14=\frac n 2 -4[/tex].
Remaining steps [tex]= n - \left(\frac n 2 -4 \right)=\frac n 2 +4[/tex]
Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,
[tex]\frac n 2 +4 = 20[/tex]
[tex]\Rightarrow \frac n 2 = 20-4=16[/tex]
[tex]\Rightarrow n = 16 \times 2 = 32.[/tex]
Hence, there are 32 steps on the ladder.

6. Kiera is comparing the cost of two swimming pool memberships to determine which she will buy. Pool K charges a $30 membership fee plus $5 per visit. Pool M charges a $10 membership fee plus $10 for every two visits. Part A. For each pool, write an equation that represents C, the total cost for n visits. Identify the slope and intercept of each equation.
Answer:
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Step-by-step explanation:
Total cost [Pool] = Fixed (membership) cost + Variable cost (per visit)
Intercept is part at which equation line intersects x or y axis. In pools case, it is fixed (membership) cost. Slope is change in y due to change in x. In pools case, it is variable cost (per visit)
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
where V = number of visits.
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10

how do you find areas of shapes
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Swimmers best time in event is 53.87 seconds. On average, his best time decreases by 0.28 seconds each of the next five times he swims the event. Does he accomplish his goal of swimming the event in less than 52.5 seconds?
Answer: Yes. This is because his fifth attempt was 52.47 seconds
Step-by-step explanation:
From the question, we are informed that Swimmers best time in event is 53.87 seconds and that on average, his best time decreases by 0.28 seconds each of the next five times he swims the event.
The time for the fifth time he swim will be:
= 53.87 - 5(0.28)
= 53.87 - 1.4
= 52.47 seconds
This means that he accomplish his goal of swimming the event in less than 52.5 seconds.
I am a six digit number. One of my sevens is worth 700,000. The other seven is worth 1/10 as much. My eight is worth eight 100s. My nine is worth 90. My other digits are zero. What number am I?
Answer:
The six digit number is 7,70,890
Step-by-step explanation:
Six digit number
One of my seven is = 700,000
Other seven is 1/10 of 700,000 = 70,000
Eight is worth 8 100s = 800
Nine is worth 90 = 90
Other digits are zeros = 0
Upon adding all these we get = 7,70,890
The six digit number is 7,70,890
What two numbers multiply to 11 and add to -12
Answer:
-11 and -1
Step-by-step explanation:
if you multiply -1 and -11, hte negatives will cancel out and it will be positive 11
if you add -11 and -1 the answer will be -12
The two numbers whose multiplication will give 11 and the add will be -12 are -1 and -11.
A quadratic equation is an algebraic expression whose power is raised to the second degree.
Mathematically, it can be expressed as:
ax² + bx + c = 0
For more examples, we can have x² -12x + 11 = 0
The way this is solved is that we are going to look for two numbers, in which:
the multiplication of these two numbers will be = 11the addition of those two numbers will be = -12Therefore, the two numbers are -1 and -11
SO, our quadratic equation can be re-written as:
x² - 1x - 11x + 11 = 0
x(x - 1) -11(x - 1) = 0
(x - 11 ) (x - 1) = 0

White people are literally the most racist people on earth! They are 63% more racist then any other race.
Answer:
yep
Step-by-step explanation:
Answer:
what you just said is racist in itself, it is also wrong. If you put 1 million white people in a room with 1 million black people statistics prove there will be more racist people of color. The reason why there are more white racist people world wide is because there are more white people than any other race alive to this day, so if you want to be smart about it you would know how to make it even. It's also 30% as well compared to 39% of racist black people.

The average person uses 6 square feet of area. If we have a 30 ft by 15 ft room with walls 10 ft high, approximately how many people could stand up in the room?
Answer:
300persons
Step-by-step explanation:
First we need to find the total surface area of the room expressed as;
Total surface area = 2(LW+LH+WH)
L is the length = 30ft
W is the width = 15ft
H I the height = 10ft
Substitute
TSA = 2{(30(15)+30(10)+15(10)}
TSA = 2(450+300+150)
TSA = 2(900)
TSA = 1800ft²
Since an average person uses 6 square feet of area, the total numwr of people that can stand up the room is expressed as;
Total people = TSA/average area per person
Total person =1800/6
Total person = 300persons
Hence 300persos can stand up the room
