Answer:
Step-by-step explanation:
Bill = 55% of the entire collection
Bob = 45% of the entire collection (Since we know 100 - 55 = 45)
We are also told that Bob received 360 cards.
This means that 45% = 360 cards.
First step is to find how many cards is 1%. To do this, divide 360 by 45.
1% of entire collection = [tex]\frac{360}{45} = 8[/tex] cards
This means that since Bill gets 55% of the entire collection, you multiply 8 by 55.
Bill = 8 x 55 = 440 cards.
Answer:
440

In a sequence of numbers, a3=0, a4=4, a5=8, a6=12, and a7=16. Based on this information, which equation can be used to find the nth term in the sequence, an?
Answer: aₙ = -12 + 4*n
Step-by-step explanation:
We know that:
a₃ = 0
a₄ = 4
a₅ = 8
a₆ = 12
a₇ = 16
This seems to be an arithmetic sequence.
To test this, we need to calculate the difference between any two consecutive terms in the sequence, and this must be a constant for any pair that we choose.
a₄ - a₃ = 4 - 0 = 4
a₅ - a₄ = 8 - 4 = 4
a₆ - a₅ = 12 - 8 = 4
etc
we can conclude that this is an arithmetic sequence.
The n-th term in an arithmetic sequence, where the increase between consecutive terms is 4, is:
aₙ = aₙ₋₁ + 4.
Another way is:
aₙ = a₀ + n*4.
Where to find a₀, we can start with the value that we know and go back:
a₂ = a₃ - 4 = -4
a₁ = a₂ - 4 = -8
a₀ = a₁ - 4 = -12
Then the n-th term can be written as:
aₙ = -12 + 4*n

Question:
A recipe says to use 3.5 cups of flour to make 48 cookies. What is the constant of proportionality that relates the number of
cookies made, y, to the number of cups of flour used, x Round your answer to the nearest tenth
es -
HELP ASAP
Answer:
13.7 cookies per cup
Step-by-step explanation:
Here, we want to write the constant of proportionality that relates the number of cookies to the
number of flours.
What we do
simply here is to divide the number of cookies by the number of cups of flowers
That would be;
y/x = 48 cookies/3.5 cups = 13.7 cookies per cup
How much time will Alex need to walk to his school, which is 2 1/4 miles away from his house, if he would walk with the speed of
4 1/2 mph
-7x-8=x-8(1-5x)
Help me please
Answer:
The answer is x = 0
Step-by-step explanation:
-7x - 8 = x - 8(1-5x)
Simplify and FOIL.
-7x - 8 = x - 8 + 40x
-7x - 8 = 41x - 8
Add 7x to both sides.
-8 = 48x - 8
Add 8 to both sides.
0 = 48x
x can only be 0 to multiply it by any other number and get 0.
x = 0

8. Write the standard form of the equation y + 4 = - 12 (x – 1).
Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16
2) Consider the following system of three equations:
(I added an image)
===============================================
Explanation:
Subtract the second equation from the first one
[tex]\ \ \ \ 3x+3y-5z = 4 \ \ ... \text{ eq 1}\\-(4x-4y+z = -1) \ \ ... \text{ eq 2}\\---------\\\ \ -x+7y-6z = 5[/tex]
Let's call that result equation 4.
Now focus on equation 3 and equation 4
equation 3 is -x+7y-6z = 2
equation 4 is -x+7y-6z = 5
Note how the left hand sides are identical, but the right hand sides are different. This means that we have an inconsistent system with no solutions. No matter what numbers we pick for x,y,z, there is no way to make all three given original equations to be true.
Find the maximum or minimum value of the parabola.

A group of people were asked if Marilyn Monroe had an affair with JFK. 184 responded "yes", and 387 responded "no". Find the probability that if a person is chosen at random, the person does NOT believes Marilyn Monroe had an affair with JFK.
Probability (round to 4 decimal places)
Answer:
0.6778 to 4 dec. places.
Step-by-step explanation:
That is 387 / (184+387)
= 387 / 571
= 0.677758

Which of the following does not represent a function? (1 point)
Answer this as quick as possible
Answer:
The oval
Step-by-step explanation: A function must pass the vertical line test.
Answer:
The third one (oval)
Step-by-step explanation:
To see if something is a function or not, you do the vertical line test. So just draw lines vertically over the x-values. If an x-value has more than one y-value then it is not a function. It is a relation.
