Artie
25%
Len
20%
Wen
30%
Gina
25%
Artie, Len, Gina, and Wen divided a carton of baseball cards as shown in the circle graph above. If Wen's
share was 60 cards, what was Gina's share of the cards?
25
50
100
200
Answer:
50
Step-by-step explanation:
Wen: 30% of the total number of cards = 60 cards
Set this up as an equation
30/100 = 60/x
Cross multiply
30 × x = 100 × 60
30x = 6000
Divide both sides by 30 to isolate the variable
x = 200
There are 200 cards total
Gina: 25% of the total 200 cards
Set this up as an equation
25/100 = x/200
Cross multiply
25 × 200 = 100 × x
5000 = 100x
Divide both sides by 100 to isolate the variable
50 = x
Gina's share is 50 cards

Part of a cross-country skier's path can be described with the vector function r = <2 + 6t 2 cos(t), (15 − t)(1 sin(t))> for 0 ≤ t ≤ 15 minutes, with x and y measured in meters.
The derivatives of these functions are given by x′(t) = 6 − 2sin(t) and y′(t) = −15cos(t) + tcos(t) − 1 + sin(t).
Find the slope of the path at time t = 4. Show the computations that lead to your answer.
Find the time when the skier's horizontal position is x = 60.
Find the acceleration vector of the skier when the skier's horizontal position is x = 60.

1. What is the prime factorization of 402? *
Your answer
Answer:
Step-by-step explanation:
Prime factorization requires dividing by primes starting with smallest prime number
402/2=201
201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is
2X3X67

Answer:
The most feasible answer would be the first option - 47
Step-by-step explanation:
This is true because if we look at the triangle it looks as if the sides have equal length, but if we look closely we will notice that the b side is angled more by a slight inch, compared to the other side, thus your answer should be 47 - the first option
If CA= 4x and CB= 8x-12 , what is the length of CA ?
Answer:
Step-by-step explanation:
CA and CB are both opposite equal 90 degree angles so are equal so we can say
8x-12=4x
4x-12=0
4x=12
x=3, since CA=4x
CA=4(3)=12

45:54
70:x
45/54=70/x
45x=70x54 - cross multiply
x=70x54/45 - divide by 45
x=84
The difference between four times a number x and 5 is 24.
Answer:
4x - 5 = 24
x= 7.25
Step-by-step explanation:
4x - 5 = 24
4x= 24 + 5
x = 29 / 4 = 7.25

6. The number of bacteria N in a culture is given by the model N(t) = 250e 0.0156 where t is the time in hours.
Find how many hours it takes for the original population to double. Round your answer to the nearest hundredth
of an hour.
i just need to know how to work this out!! please help
Answer:
t ≈ 44.43 hours
Step-by-step explanation:
Expression that models the population of a bacteria after time 't' is,
N(t) = [tex]250(e^{0.0156t})[/tex]
Here initial population = 250
And N(t) = Population after 't' hours
t = duration
We have to find the duration in which bacterial population gets doubled.
N(t) = 2×250 = 500
From the given expression,
500 = [tex]250(e^{0.0156t})[/tex]
[tex]e^{0.0156t}=2[/tex]
[tex]\text{ln}(e^{0.0156t})=\text{ln}(2)[/tex]
0.0156t[ln(e)] = 0.693147
0.0156t = 0.693147
t = [tex]\frac{0.693147}{0.0156}[/tex]
t = 44.432
t ≈ 44.43 hours

You are applying for a fuel tax rebate. The amount of fuel road tax is 32 cents per gallon. If the refund is 50 % of this amount, what is the refund for 8,000 gallons of fuel?
Answer: $1,280
Step-by-step explanation:
The refund one a gallon is 50% of the cost of the gallon which is $0.32.
The refund on a gallon is:
= 50% * 0.32
= $0.16
If it was for 8,000 gallons the refund would be:
= 8,000 * 0.16
= $1,280

What is the solution to the system of equations? y = x + 3 3x - 4y = -7
Answer:
x=-5 & y=-2
Step-by-step explanation:
Step 1: Solve y=x+3 for y:
y=x+3
Step 2: Substitute x+3 for y in 3x-4y =-7:
3x-4y=-7
3x-4(x+3)=-7
-x-12=-7 (Simplify both sides of the equation)
-x-12+12=-7+12 (Add 12 to both sides)
-x=5
-x/1=-5/-1 (Divide both sides by -1)
Step 3: Substitute -5 for x in y=x+3:
y=x+3
y=-5+3
y=-2 (Simplify both sides of the equation)
x=-5 and y=-2

The more often a lie is told, the more people will believe it. Many mathematical models for this psychological ploy exist
Answer:
hello your question is incomplete attached below is the complete question
answer : The vertical asymptote is not relevant since a negative population holds no relevance ( option 3 )
Step-by-step explanation:
attached below is the Graph of P(x) plotted using online tools as part of the solution requested by the question
From the attached graph vertical asymptote is x = 0
Also from the graph the x-intercept is (2, 0) which means that whenever a lie is told twice, Nobody believes the lie ( i.e. y = 0 when x = 2 )

How would you “find “x” in the diagram?
Answer: D
9514 1404 393
Explanation:
We have to assume the triangle is a right triangle.
In a 30°-60°-90° right triangle the side lengths have the ratio ...
short side : long side = 1 : √3
This lets you write the proportion ...
x/15 = 1/√3
Multiplying by 15 gives ...
x = 15/√3 . . . . . . matching choice D
__
There are other ways to get there. One of them is ...
x = 15·tan(30°) = 15/√3
