Answer:
Katie runs fastest
Step-by-step explanation:
For us to know the person who runs fastest, we need to calculate their speed in feet per seconds (ft/s)
For Tony; his speed is 12ft/s
For Katie;
Katie runs 450 feet in 30seconds;
450 feet = 30 secs
x = 1 sec
Cross multiply
30x = 450
x = 450/30
x = 15ft
Hence Katie runs 15ft/s
For Frank;
Frank ran 1 mile per 577secs
1 mile = 5280feeet
This mean that he ran 5280feet in 577 secs
5280feet = 577secs
y = 1 secs
cross multiply;
577y = 5280
y = 5280/577
y = 9.15ft/s
Hence Frank ran 9.15ft/s
For Adam;'
If Adam ran 880 ft in 1 minutes, this means he ran 880ft in 60secs
880 ft = 60secs
z = 1sec
Cross multiply
60z = 880
z = 880/60
z = 14.67ft/s
Hence Adam ran 14.67ft/s
From the value of their speed, we can see that Katie runs fastest with a speed of 15ft/s

15x+12=19x-24
what is the answer? help me please
9
Step-by-step explanation:
15x+12=19x-24
15x-19x=-24-12
-4x=-36/÷(-4)
x=9
You first put all the x on one side and numbers on the other and be careful about + and - and then you divide by everything with the x so you have only the x left and you get the aswer.

A high school is doing a fundraiser selling magazine subscriptions. The magazine publisher will pay the school a starting bonus of $500 and they $4 for each magazine subscription sold. At the end of the fundraiser the school is paid $1300. How many subscriptions did they sell?
Answer:
200
Step-by-step explanation:
You can use the equation 1300=4x+500
Starting bonus ($500) is like the y intercept so you would get that out of the way by subtracting 500 from both side
1300-500=800
500-500=0
Your equation is now:
800=4x
Now since the question is How many subscriptions did they sell and we know that each magazine is $4 all for have to do is divide both sides by 4 to get the answer.
800÷4=200
4x÷4=x
x=200

If m<2= 123, m<12=38 and m<18=100, find the measure of each missing angle.
Answer:
see below
Step-by-step explanation:
a) ∠1 = 180 - 123 = 57°
b) ∠3 = 100° (congruent to ∠18)
c) ∠4 = 180 - 100 = 80°
d) ∠5 = 123° (opposite to ∠2)
e) ∠6 = 57° (opposite to ∠1)
f) ∠7 = 38° (alternate angle to ∠12)
g) ∠8 = 180 - ∠7 - ∠9 = 180 - 38 - 100 = 42°
h) ∠9 = 100° (congruent to ∠18)
i) ∠10 = 57° (congruent to ∠1)
j) ∠11 = 180 - ∠10 - ∠12 = 180 - 57 - 38 = 85°
k) ∠13 = 100° (parallel angle to ∠3)
l) ∠14 = 80° (parallel angle to ∠4)
m) ∠15 = 123° (parallel angle to ∠5)

A company has determined that 2 out of every 5255 bolts that it ordered is defective. What is the probability that that a worker will pick a bolt that is not defective? Enter your answer as a reduced fraction using / for the fraction bar. Do not use any spaces in your answer.
Answer:
5253 out of 5255 times.
[tex] \frac{5253}{5255} [/tex]
Step-by-step explanation:
Being that the we are determining the probobility of it not bein defecteve, then we simply count the bolts not defective rather then defective ones. We can do this simply by subtracting the defective bolts from 1, or total bolts recieved.
[tex]1 - \frac{2}{5255} [/tex]
Which is the equation that gives us the answer,

Step-by-step explanation:
let width be X
then length will be 3x
2(3x+X)=64
3x+X=32
4x=32
X=8
then 3x=24
Does the following picture represent a linear function?
Answer: No
Step-by-step explanation: For x 0-2, the y is increasing by +5 every time. However, the moment it hits x=2, it starts decreasing by -5 every time. This means that it does not follow on set pattern (either +5 or -5) and looks more like a ^ than a /.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. It is same as slope.
We have a plant grows at a constant rate.
The data recorded by Daniel is as follows -
Week 4 12 inches
Week 5 15 inches
Week 6 18 inches
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. We have to find the slope of the line represented by the data as -
K = slope
K = (15 - 12)/(5 - 4)
K = 3/1
K = 3
Therefore, the constant of proportionality is 3 inches/week.

Lucy cuts 4 squares with side length x in. From the corners of a 6 in. By 9 in. Cardboard rectangle. She folds the remaining cardboard to make a tray that is x in. High. Write and simplify a function for the volume V of the tray in terms of x.
Answer:
4x³ - 30x² + 54x
Step-by-step explanation:
Length of the rectangular cardboard = 9 inches
Width of the rectangular cardboard = 6 inches
if the square of sides x inches is cut from each corner of the rectangular cardboard and folded to make a tray, then we have
Length of the tray = length of cardboard - 2(side of square )
= 9 - 2x
Width of the tray = width of cardboard - 2( side of square)
= 6 - 2x
height of tray = sides of square
= x
volume of tray = Length × width × height
= (9 - 2x) (6 - 2x) (x)
Open the parenthesis
= (54 - 18x - 12x + 4x²)(x)
= 54x - 18x² - 12x² + 4x³
= 54x - 30x² +4x³
Re-arrange
4x³ - 30x² + 54x
Volume, V of the tray in terms of x = 4x³ - 30x² + 54x
Answer:
4x^3-30x^2+54x

When invested at an annual interest rate of 4.7%, an account earned $1,290.33 of simple
interest in 3 years. How much money was originally invested? If necessary, round to the
nearest cent.
O $82,361.49
O $9,151.28
O $20.22
O $91,512.77
Answer:
The answer is 82,361.49
Step-by-step explanation:
after simplifying the equation, the problem is 1290.33 divided by .27 times 3 - the quotient is 82,362.49 (in simplified form)
The amount of money that he originally invested will be $9,151.28. Then the correct option is B.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
When contributed at a yearly loan fee of 4.7%, a record acquired $1,290.33 of straightforward interest in 3 years.
Then the amount of money that he originally invested will be given as,
1290.33 = (P x 4.7 x 3)/100
Simplify the equation, then we have
1290.33 = (P x 4.7 x 3)/100
129033 = 14.1 x P
P = 129033 / 14.1
P = $9,151.28
The amount of money that he originally invested will be $9,151.28. Then the correct option is B.
