A jar contains 100 marbles. There are 7 blue marbles, 4 green marbles,
46 red marbles, and 43 yellow
marbles. What is the probability of
randomly selecting a yellow marble?
Enter the correct answer.
Answer:
43%
Step-by-step explanation:
If there are 43 yellow marbles out of 100 total, the fraction that will be used is 43/100. The percentage is found by dividing the numerator (top) by the denominator (bottom). The percentage is the first two numbers in the decimal. For future reference, if a decimal were to have more than 2 or 3 digits, the number would be rounded to the 4th and the decimal point would be placed between the 2nd and 3rd digits.
a pet store has 2 gray rabbits. one eight of the rabbits at the pet store are gray. how many rabbits does the pet store have?
2 = 1/8
2 x 8 = 16
16 = 8/8
2 gray rabbits is 1/8 of 16. The store has 16 rabbits.
because if 2 rabbits are gray. and is those two = 1 eighth. then two rabbits would equal 1 out of eight. so whats two x eight? 16. it just seems like the logical answer.

2 Richard and Jason each begin filling pools at the same time.
• Richard fills his pool at a rate of 6 gallons per minute.
• Jason's pool already contains 200 gallons, and he fills it at a rate of 2 gallons per
minute.
The quantity of the liquid in Richard's tank after 20 minutes will be 120 gallons and in Jason's tank will be 240 gallons.
What are gallons?
A gallon is a British unit which is used for the measurement of liquids that is equal to eight pints. In Britain, it is equal to about 4.546 litres. In America, it is equal to about 3.785 litres.
It is given in the question that:-
Richard fills his pool at a rate of 6 gallons per minute.
Jason's pool already contains 200 gallons, and he fills it at a rate of 2 gallons per minute.
After 20 minutes the amount of liquid in the tank will be:-
For Richard = 6 gallons per minute. x 20 minutes= 120 gallons
For Jason= 2 gallons per minute x 20 =40 gallons
Jason has 200 gallons already in the tank
So it will become = 200+24=240 gallons.
Hence quantity of the liquid in Richard's tank after 20 minutes will be 120 gallons and in Jason's tank will be 240 gallons.

The function will be a (linear function) linear equation in two variable and the equation of the function is y = 87x - 783
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have given data:

Attendance(y): 348 435 552 609 696 783
If plot these points on a coordinate plane, we will see these points will align in a straight line.
We know we can find a line equation with two points:
(13, 348) and (14, 435)
[tex]\rm (y - 435) = \dfrac{435-348}{14-13}(x-14)[/tex]
y - 435 =87(x-14)

A wiring job requires 5,127 feet of cable. If the cable comes in 250-foot coils, how many coils of cable are required?
Answer:
20.58 (21)
Step-by-step explanation:
5127/250 = 20.58
if the coils are only be imported in full form your gonna need 21
Answer:
21 cables
Step-by-step explanation:
Because the cables come in 250-foot coils, you cannot have a piece of one cable. So, if you take the total amount of cable you need (5,127 feet) and divide it by how long a single cable is (250 feet).
5,127 divided by 250 is 20.508, but you cannot have a piece of one cable. So, you round up to the nearest whole number, 21.

The piece of board cut off

Answer:
Number of logs:
1. 48
2. 14
3. 90
4. 48
5. 100
Total: 300
Step-by-step explanation:
Just multiply the height with the number of trees then divide by 6. This is in theory if the length of all the trees were conjoined, as there would most likely just be less, then 300. This is because the remainder would be that of the multiplied trees height instead of getting the remainder of wood from each tree. So in case you want to try doing that option, simply divide the height first in feet by 8, then multiply that by the number of trees to give you an accurate answer of logs.
Answer:
see attached
total: 300 logs
Step-by-step explanation:
When calculations are repetitive, it is convenient to let a spreadsheet do them.
Here, the number of logs per tree is found by dividing the tree height by 8 feet. The number of logs from trees that height will be found by multiplying the number of trees by the number of logs that height will give.
The total number of logs is the sum of the numbers from all the tree heights.

The total number of logs is 300. (The rightmost column of the attached spreadsheet matches the rightmost column of your table.)
A quadratic function has zeros −3 and 5 and contains the point (4, 14).
a) Find the equation of the quadratic function in standard form.
b) Complete the square to determine the vertex of the function.
c) Find the equation of a second quadratic function in the same family as the function in part that contains the point (1, −48).
The quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).
What is a quadratic equation?A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic equation is,
ax²+bx+c=0
Here,(a,b, c) is the real numbers and (x) is the variable.
A quadratic function has zeros −3 and 5 and contains the point (4, 14). The factored form of quadratic equation is,
f(x)=a(x-z₁)(x-z₂)
Here, z₁ and z₂ are the zeros. Thus,
f(x)=a(x-z₁)(x-z₂)
f(x)=a(x-(-3))(x-5)
f(x)=a(x+3)(x-5)
This equation contains the point (4,14). Thus,
14=a(4+3)(4-5)
14=a(7)(-1)
a=14/-7
a=-2
Put the value in above equation and solve it further:
f(x)=-2(x+3)(x-5)
f(x)=-2(x²-5x+3x-15)
f(x)=-2x²-4x-30
Change the sign,
f(x)=2x²+4x+30
The equation of the quadratic function in standard form is,
f(x)=2(x+1)²+28
Thus, the vertex point are -1 and 28. Similarly, the section equation which contains the point (1, −48) can be solved.
Hence, the quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).

Find the slope of a line with equation 4y + x = 8.
Answer:
m = -1/4
Step-by-step explanation:
4y + x = 8
Arrange the equation in a slope intercept form y = mx+b, where m is the slope
4y + x = 8, subtract x from both sides
4y = -x +8, divide both sides by 4
y = -x/4 + 8/4 , simplify
y = -x/4 + 2, compare this to the general form y=mx+b and we see that the slope m = -1/4
Answer:
m = -1/4
Step-by-step explanation:
4y + x = 8
Arrange the equation in a slope intercept form y = mx+b, where m is the slope
4y + x = 8, subtract x from both sides
4y = -x +8, divide both sides by 4
y = -x/4 + 8/4 , simplify
y = -x/4 + 2, compare this to the general form y=mx+b and we see that the slope m = -1/4
