Answer:
8 m^2
Step-by-step explanation:
4x2=8 and if it needs to be in sq meters it is 8 m^2 (m^2 means meters squared)
The perimeter of a square is twenty-eight
inches. What is the length of each side?
The perimeter of any shape is given by the sum of it's all sides and as here the shape is square so it's all sides must be equal and it have 4 sides. So if we assume it's one side to be s , then perimeter = (s+s+s+s) = 4s , so in our question :
[tex]{:\implies \quad \sf 4s=28}[/tex]
[tex]{:\implies \quad \sf s=\dfrac{28}{4}=7}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{s=7\:\: inches}}}[/tex]
Hence , the length of each side of the square is 7 inches

Answer:
mDBC = 341 °
Step-by-step explanation:
Arc DBC is almost the whole circle, if you were to exclude the degree measure of minor arc DC; which is, in other words m∠ DPC
Now by Vertical Angles Theorem:
m ∠ DPC = m∠ APB, ⇒ provided BD, and AC are diameters
m∠ DPC = 19°
This would mean ⇒
mDBC = 360 - m∠ DPC,
mDBC = 360 - 19,
mDBC = 341 degrees ( ° )
What is the greatest common factor GCF of 45 and 81?
Answer:
GCF = 9for the values 45, 81
Solution by Factorization:The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 81 are: 1, 3, 9, 27, 81
Then the greatest common factor is 9.
Answer:
9Step-by-step explanation:
Factor of 45: → 1, 3, 5, 9, 15, 45
Factor of 81: → 1, 3, 9, 27,81
Therefore, GCF of 45 and 81 is 9

when a kitten is born it weighs 1.5 pounds. after 3 weeks it weighs 3 pounds. when the kitten is 6 weeks old it weighs 7.5 pounds. what percent weight gain did the kitten grow over from the first weight?
Answer:
It grew by 500% meaning it grew on average 83.333% per week
Step-by-step explanation:
To find the percent growth you divide the end weight by the starting weight:
[tex]7.5/1.5=5[/tex]
However, that is the percentage in decimal form. To convert that number to a percentage move the decimal place to the right 2 places. This results in 500%
To get the average weekly growth weight, simply divide the 500% by the amount of weeks (6). This then gives the 83.333% per week.
Note: I didn't know which answer you were looking for. That is why there are 2.

A helicopter company offers tours of the city. They charge $100 dollars initially, and then $50 for each additional person. The graph below shows the charges for a tour (T) based on the number of people (p).Write the equation of the line that relates the tour charges (T) to the number of people (p).
Answer:
100 + 50p = t or t = 100 + 50p
Step-by-step explanation:
We know that they charge 100 initially and then an addition 50 for each person.
We add 100 to 50 but we do not know the amount of people, which leaves it unknown (p)
The total cost (t) is also unknown which stays unknown until we calculate the amount of people.

Vertex Form of a quadratic expressionGiven the quadratic expressions
1.5x^2+6x+......
1.5(x^2 + 4x)
Using the completing the square method
The coefficient of x = 4
Half of the coefficient = 4/2 = 2
The square of the result = 2^2 = 4
The equation is expressed as:
f(x) = 1.5(x^2+4x+ 4) - 4
f(x) = 1.5(x+2)^2 - 4
