Last month the Zimmer family had 20 chickens. This month they have 25. What is the percent increase from last month to this month?
Answers
Answer:25 %
Step-by-step explanation:
Given
Last month count of chicken was [tex]20[/tex]
The current count of chicken is [tex]25[/tex]
The percentage increase is given by
[tex]\Rightarrow \dfrac{\text{Present value-Actual value}}{\text{Actual value}}\times 100[/tex]
Putting values
[tex]\Rightarrow \%=\dfrac{25-20}{20}\times 100=\dfrac{5}{20}\times 100\\\\\Rightarrow \%=25\%[/tex]

Answers
Considering that it has only positive probabilities, and the sum of the probabilities is of 1, the table that shows a probability distribution is given by:
X 0 1 2 3
P 0.1 0.5 0.3 0.1
When does a table represent a probability distribution?A table is formed by a set of points (x, P(x)), and represents a probability distribution if:
The sum of the probabilities is of 1.All probabilities are 0 or positive.In this problem:
In the first table, there is a negative probability, which is P(X = 0) = -0.3.In the second and the fourth tables, the sums are of 1.2 and 0.8, respectively.Hence, the table that represents a probability distribution is given as follows:
X 0 1 2 3
P 0.1 0.5 0.3 0.1

A ball is thrown straight up from a height of 3 ft with a speed of 32 ft/s. Its height above the ground after x seconds is given by the quadratic function y = -16x2 + 32x + 3.
Answers
Answer:
19ft
Step-by-step explanation:
Given the height of a ball above the ground after x seconds given by the quadratic function y = -16x2 + 32x + 3, we can find the maximum height reached by the ball since we are not told what to look for.
The velocity of the ball is zero at maximum height and it is expressed as:
V(x) = dy/dx
V(x) = -32x+32
Since v(x) = 0
0 = -32x+32
32x = 32
x = 32/32
x = 1s
Get the height y
Recall that y = -16x² + 32x + 3.
Substitute x = 1
y = -16(1)²+32(1)+3
y = -16+32+3
y = -16+35
y = 19ft
Hence the maximum height reached by the ball is 19ft

Answers
Answer:

Step-by-step explanation:
2x² + 4x + 1x + 2
They are already arranged, so you just have to find the GCF. 2x² + 4x have the GCF of 2 and 1x + 2 have the GCF of 1.
2x (x + 2) + 1(x + 2)
Now you divide the whole thing by x + 2.
2x (x + 2) + 1(x + 2)/ x + 2
One of them cancels out leaving (2x + 1) and (x+2)

Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon.
a. How long is the red ribbon if the blue ribbon is:
10 inches?
27 inches?
X inches?
Answers
Answer:
If blue ribbon is 10 inches, red ribbon is 3 inches
If blue ribbon is 27 inches, red ribbon is 20 inches
If blue ribbon is x inches, red ribbon is x - 7 inches
Step-by-step explanation:
Given that,
The length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon.Need to find,
How long red ribbon is if blue ribbon is 10 inchesHow long red ribbon is if blue ribbon is 27 inchesHow long red ribbon is if blue ribbon is x inches--------------------------------------------------------------------------------------------------------------
How long is the red ribbon if the blue ribbon is 10 inches?
We know that the formula for find the length of the red ribbon is:
length of blue ribbon - 7 inches = length of red ribbon
Since we know the length of the blue ribbon (10 inches), we can apply that to the formula:
10 inches - 7 inches = length of red ribbon
So, what is 10 - 7? That gives us 3. So, the length of the red ribbon is 3 inches if the length of the blue ribbon is 10.
--------------------------------------------------------------------------------------------------------------
How long is the red ribbon if the blue ribbon is 27 inches?
We do the same as we did above to get 20 inches as the final answer because 27 inches - 7 inches gives us 20 inches as a difference.
--------------------------------------------------------------------------------------------------------------
How long is the red ribbon if the blue ribbon is x inches?
Since we do not know the value of x, we keep the length of the red ribbon to x - 7.
The length of the red ribbon is 3 inches if the blue ribbon is 10 inches.
The length of the red ribbon is 20 inches if the blue ribbon is 27 inches.
The length of the red ribbon is (X - 7) inches if the blue ribbon is X inches.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Length of blue ribbon = x
Length of red ribbon.
= x - 7
Now,
If x = 10
Length of red ribbon.
= 10 - 7
= 3 inches
If x = 27
Length of red ribbon.
= 27 - 7
= 20 inches
If x = X
Length of red ribbon.
= (X - 7) inches
Thus,
The length of the red ribbon is given above.

Answer:

Area of Triangle:

400 + 200 = 600
Good luck! <3
Answer:
The total area of the shape is 600 square centimetres.
Step-by-step explanation:
You can solve this by finding the area of the square and the triangle separately.
The area of any rectangle, including squares, is width times height. The bottom square then has an area of 20cm × 20cm, which equals 400cm²
The area of a triangle is have of its base width times its height. It too has a width of 20cm and a height of 20cm, so its area is 20cm × 20cm ÷ 2, which equals 200cm²
Add them together for the full area of the shape:
400cm² + 200cm² = 600cm²
