Alex, Cameron and Sam are all taking part in a 400 m race.
They are each running at a different constant speed.
Alex is running 12% faster than Cameron, whilst Sam is running 2% slower than Cameron.
When Alex crosses the finish line, how many metres is Sam from the finish line?
Answer:
A= C + 12%C = 1.12C
S=.C -2%C = .98C
A,C and S are the speeds of Alex, Cameron and Sam
400 meter race
how far is Sam from the finish line when Alex crosses the finish line?
distance = speed times time
400 = AT where T=Alex' finish time
400=1.12T
400=CU where U = Cameron's finish time
400=SV where V = Sam's finish time
T<U<V
Alex' finish time is less than Cameron's finish time is less than Sam's finish time
if Cameron runs at 20 meters per second, finishing in 20 seconds
then Sam is about 50 meters from the finish line when Alex finishes

write a real world situation for which the rate of change is -15
The most appropriate choice for velocity and accleration will be given by- Deacceleration of a car of 15 [tex]m/s^2[/tex] is a real world situation for which the rate of change is -15
What is velocity and acceleration?
Velocity
The distance travelled by a body per unit interval of time where the direction of the motion of a body is taken into account is known as velocity.
Velocity is a vector quantity as direction of motion of body is taken into account.
If d is the displacement of body and t is the time,
Velocity = [tex]\frac{d}{t}[/tex]
Acceleration
The rate of change of velocity of a body is called acceleration.
Acceleration is a vector quantity as direction of motion of a body is taken into account.
If [tex]\Delta[/tex]v is the change of velocity and t is the time,
Acceleration = [tex]\frac{\Delta v}{t}[/tex]
If velocity decreases then it is called Deacceleration
Here
Deacceleration of a car is 15 [tex]m/s^2[/tex]
That means rate of change of velocity of a car is -15 [tex]m/s^2[/tex]
This is a real world situation for which the rate of change is -15

Write the equation for the line that passes through the given point and is perpendicular to the given line (1,7); x - 4y = 8
The equation for the line that passes through the given point and is perpendicular to the given line is x - 4y = 3
Given : x - 4y = 8
4y = x- 8
On dividing by 4 we get;
y= x/4 - 2
This is of the form y = mx + c
Thus m in this case on comparing we get m= 1/4
We know the formula of the slope ;
y - y₁ =m ( x - x₁ )
y - 1 = 1/4 ( x- 7)
On cross multiplying we get ;
x- 4y = 3
Thus the equation for the line that passes through the given point and is perpendicular to the given line is x - 4y = 3 .

What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
Where -
[m] is the slope of the line.
[c] is the y - intercept.
Given is the following equation-
g(x) = 3/4 f(x)
Since, the functions are not given, we will assume them by ourselves. You can use the same procedure for any pair of functions of the form -g(x) = n f(x)
Assume that -
f(x) = 2x + 1
Now -
g(x) = (3/4) f(x)
g(x) = (3/4)(2x + 1)
g(x) = (3/2)x + 3/4
Now, both the graphs f(x) and g(x) are attached below. In general, g(x) is a dilated form of f(x) and the dilation scale factor [K] in this case is (3/4).
Therefore, the function g(x) is a dilated form of f(x) and the dilation scale factor [K] in this case is (3/4). The graphs f(x) and g(x) are attached with the answer.

The personal assets and liabilities of a carpenter are listed below.
What is the carpenter's net worth?
$139,450
$145,228
$281,313
$284,678
$139,450
==========================================================
Explanation:
asset = an item that is either cash or can be turned into cash
liability = something that needs to be paid back (eg: truck loan)
A = total assets
A = (homeValue) + (workEquipment) + (carValue) + (investments)
A = ( $175,742 ) + ($3,365) + ($44,346) + ($61,225)
A = $284,678
B = total liabilities
B = (mortgage)+(credit card balance)+(truck loan)
B = ($76,765)+($2,055)+($66,408)
B = $145,228
C = net worth
C = A - B
C = ($284,678) - ($145,228)
C = $139,450 which points us to choice A as the final answer.
The net worth of the carpenter is $144,633.
Given that, Home value = $175,742, Mortgage = $76,765, Credit card balance = $2,055, Owned work equipment = $3,365 and Car value = $44,346.
What is the net worth?Net worth is the value of all the non-financial and financial assets owned by an individual or institution minus the value of all its outstanding liabilities.
Here,
Net worth = Financial assets - Liabilities
= (175,742+3,365+44,346) - (76,765+2,055)
= 223,453 - 78,820
= $144,633
Therefore, the net worth of the carpenter is $144,633.

I don’t get it I have to find the exterior angle (t+20)
Answer:
110
Step-by-step explanation:
To find the measure of the exterior angle we first need to find the value of t.
The sum of interior angles in a triangle is equal to 180° so we can write the following equation:
t + 10 + t + t + 20 = 180 add like terms
3t + 30 = 180 subtract 30 from both sides
3t = 150 divide both sides by 3
t = 50
The exterior angles and the angle represented with t + 20 make a straight line
and they are supplementary angles so their sum is equal to 180
t + 20 = 70 to complete this to 180 we need 110
1. consider a lottery with three possible outcomes: $125 will be received with probability 0.25, $100 will be received with probability 0.3 and $50 will be received with probability 0.45. a. what is the expected value of the lottery? b. what is the variance of the outcome? c. what would a risk-neutral person pay (at most) to play the lottery?
The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975
C) A risk-neutral person would pay $80 or less to play the lottery.

This is,
125(0.25) + 100(0.3) + 50(0.45)
= $83.75
b) we can calculate the variance as follows:
Variance=.25*(125-83.75)^2+.3*(100-83.75)^2+.45*(50-80)^2=909.6

How Do Polynomial Functions Work?Expressions with polynomial functions include variables with various degrees, non-zero coefficients, positive exponents (of variables), and constants. A polynomial in "b" of degree 2 is, for instance, f(b) = 4b2 - 6.
Likewise, (x-3) appears as a factor of p(x) once.

Gallons of gasoline = 55 gallons
Let's find the ounces of oil.
To find the ounces of oil, we have the equation:

The total surface area of the triangular prism is 756 meter²
Given,
A triangular prism and its net.
We have to find the surface area of the triangular prism.
First we can consider the right angled triangle.
Height = 9 meter
Base = 12 meter
Hypotenuse = 15 meter
Area of the right angled triangle = (1/2 bh)
Here,
Area = 2 × (1/2 bh) = 2 × (1/2 × 12 × 9) = 2 × 6 × 9 = 108 meter²
Now, area of right rectangle.
Area of rectangle = length × breadth
Here, the breadth of the rectangle is the height of the triangle = 9 meter
Length = 18 meter
Area = length × breadth = 9 × 18 = 162 meter²
Then, area of middle rectangle.
Length = 18 meter
Breadth = 12 meter
Area = length × breadth = 18 × 12 = 216 meter²
Next, area of left rectangle.
Length = 18 meter
Breadth = Hypotenuse of the triangle = 15 meter
Area = length × breadth = 18 × 15 = 270 meter²
Now, lets calculate the total surface area of the triangular prism.
Surface Area of triangular prism = 108 + 162 + 216 + 270 = 756 meter²

in a random sample of 45 endangered species, 12 are categorized as vulnerable, 11 are categorized as endangered, and 22 are categorized as critically endangered. what is the probability that a randomly selected species from this sample is vulnerable or critically endangered? group of answer choices
The probability that the randomly selected sample is vulnerable or critically endangered is equal to 0.76
The probability can be determined using the following formula;
probability = number of desired events or outcomes ÷ total number of events or outcomes
The total is known to be 45, the favorable or desired outcomes can be calculated as follows;
number of desired outcomes = number of vulnerable species + number of critically endangered species
number of desired outcomes = 12 + 22
number of desired outcomes = 34
Now we calculate the probability by using the above formula;
probability = 34 ÷ 45
probability = 0.76
Therefore, 0.76 is the probability that the randomly selected species is vulnerable or critically endangered.
