Answer:
Car BStep-by-step explanation:
The equation for the speed is:
s = d/tFrom the equation we see for the same t the speed is greater if d is greater.
We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.
It obvious the graph of the Car B will have a greater d- value.
It means that Car B has a greater speed so it is faster that Car A.
Leonel is building a circular table with a diameter of 5 feet. The wood costs $35.50 per square foot. How much will it cost Rafael to make the table? Use 3.14 to approximate π. Enter your answer in the box.
Answer:
$696.70
Step-by-step explanation:
The formula for the area of a circle is given as πr²
From the above question
π = 3.14
Diameter = 5 feet
Radius = Diameter/2 = 5 feet/2 = 2.5 feet
Hence,
The area of the circular table = 3.14 × 2.5²
= 19.625 ft² or 19.625 square foot
We are told that:
The wood costs $35.50 per square foot
Hence,
1 ft² = $35.50
19.625 ft² = x
Cross Multiply
x = 19.625 ft² × 35.50
x = $696.6875
Approximately = $696.70
Therefore, it will cost Rafael $696.70 to make the table.

Identify the initial conditions y(0) and y'(0) for the vertical motion of an object, if the object is thrown downward at a velocity of 6 m/s from a height of 30m. (take the origin to be on the ground)
Answer:
The right solution is "y(0) = 30 m" and "y'(0) = -6 m/s²".
Step-by-step explanation:
Given,
Velocity,
u = -6 m/s
Height,
h = 30 m
Now,
By using shifting of origin, we get
⇒ [tex](y-30)=-6t+\frac{1}{2}(-9.8)t^2[/tex]
[tex]y-30=-6t-4.9t^2[/tex]
[tex]y=30-6t-4.9t^2[/tex]
hence,
The value of y(0) is:
y(0) = [tex]30-0-0[/tex]
= [tex]30 \ m[/tex]
The value of y'(0) is:
y'(t) = [tex]-6-9.8t[/tex]
y'(0) = [tex]-6 \ m/s^2[/tex]

Six out of the first ten vehicles that entered a parking lot were cars. Based on this information, if five hundred forty vehicles entered the parking lot, how many vehicles could be expected to be cars?
Answer:
x = number of cars = 324
Step-by-step explanation:
Total vehicles = 10
Cars = 6
Total vehicles : cars = 10 : 6
if five hundred forty vehicles entered the parking lot, how many vehicles could be expected to be cars?
Let
x = number of cars
Total vehicles : cars = 540 : x
Equate both ratios
10 : 6 = 540 : x
10/6 = 540/x
Cross product
10 * x = 6 * 540
10x = 3240
x = 3240/10
x = 324
x = number of cars = 324

Find the z-score for which a total probability of 0.86 falls more than z standard deviations (in either direction) from the mean.
Answer:
Z-score = 0.1764 ≈ 0.18
Step-by-step explanation:
Z-score for Total probability of 0.86
This can found as shown below
P( Z < -Z ) + P( Z > Z ) = 0.86
= P ( Z < -Z ) + P ( Z < - Z ) = 0.86
= P ( Z < - Z ) = 0.86 / 2 = 0.43
hence Z-score = 0.1764 ( from standard Normal table )

Answer:
13 and 32
Step-by-step explanation:
let one number be x
Then the other number is x + 19 , then
x + x + 19 = 45
2x + 19 = 45 ( subtract 19 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The 2 numbers are 13 and 13 + 19 = 32

One-sixth of a certain number is four more
than one-twelfth the number. Find the number. a. 6 b. 18 C. 36 d. 48
let number be x
1/6x - 1/12x= 4
1/12x=4
cross multiply
x= 12 x 4
x= 48
If one-sixth of a certain number is four more than one-twelfth the number, the required number will be 48.
Let the unknown number be 'a'
One-sixth of the number is expressed as 1/6 a ..... 1
One-twelfth the number is also expressed as 1/12 a
Four more than one-twelfth the number will be written as:
1/12 a + 4 .... 2
Equating 1 and 2 will give:
1/6 a = 1/12 a + 4
a/6 = a/12 + 4
Collect the like terms
[tex]\frac{a}{6} - \frac{a}{12} = 4[/tex]
Find the LCM
[tex]\frac{2a-a}{12} = 4\\\frac{a}{12} = 4[/tex]
Cross multiply
a = 12×4
a = 48
This shows that the required number is 48

Time (days):3,4,5,6 cost($):75,100,125,150
Answer:
The rate of change is 25 and that means the cost per day is $25
Step-by-step explanation:
Since we have a constant rate of change, we can select any two points, apply the slope formula
The slope formula is;
m = (y2-y1)/(x2-x1)
(x1,y1) = (3,75)
(x2,y2) = (6,150)
m = (150-75)/(6-3) = 75/3 = 25
What the rate of change means here is that the cost per day is $25

Answer:
x=41
Step-by-step explanation:
so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:
a^2+b^2=c^2
so:
9^2 +40^2=c^2
solve for the exponents:
81 +1600=c^2
1681=c^2
and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41
hope this helps :)

The area of the square is [tex]74-16\sqrt{10}[/tex] inches².
Area of square
Let x be the length of square
then area = x²
How to find the square area?
Given the side length of a square is [tex]8-\sqrt{10}[/tex] inches.
then the area of the square is [tex](8-\sqrt{10} )^{2}[/tex]
therefore,
[tex](8-\sqrt{10} )^{2}= 8^2+(\sqrt{10})^2-2(8)(\sqrt{10})[/tex]
[tex]=64+10-16\sqrt{10}[/tex]

A survey of Lakeview High School students found that 72% of the students had eaten breakfast that morning. If two students are chosen at random from a group of 100 students, what is the probability that at least one of them did not eat breakfast that morning?
Answer:
4.26 * 10^-12
Step-by-step explanation:
Usibg the binomial probability relation :
P(x =x) = nCx * p^x * q^(n-x)
Probability of success = probability of not eating = 1 - 0.72 = 0.28
p = 0.28
q = 1 - p = 0.72
Probability that atleast one out of 2 chosen did not eat breakfast :
P(x ≥ 1) = p(x = 1) + p(x = 2)
P(x ≥ 1) = (100C1 * 0.28^1 * 0.72^99) + (100C2 * 0.28^2 * 0.72^98)
= 4.26 * 10^-12

Phoebe andy and polly share 270 phoebe gets 3 times the amount as andy does who gets twice as much as polly
Answer:
Polly's money is 30, Andy's is 60, and Phoebe's is 180.
Step-by-step explanation:
Given that
Phoebe andy and polly share 270
Phoebe gets 3 times as andy
And, andy gets twice as much as polly
let us assume the following things
B be Phoebe's money
A be Andy's money
L be Polly's money
Now following equations should be used
B + A + L = 270 .........(1)
B = 3A............(2)
A = 2L .............(3)
So,
B = 3A
= 3 × (2L)
= 6L
Now put the equation 2 and equation 3 in equation 1
So,
6L + 2L + L = 270
9L = 270
L = 30
A = 2L
= 2(30)
= 60
B = 3A
= 3(60)
= 180
Therefore, Polly's money is 30, Andy's is 60, and Phoebe's is 180.
