You have to use this equation the a=5, h=4 and b=9 and you should get the answer of 28
Answer:
El perímetro es 16, por qué para hallar el perímetro son la suma de sus 3 lados.
el área es la base por altura, que en este caso sería...
![\frac{6cm \times 4cm}{2} = 12cm](https://tex.z-dn.net/?f=%20%5Cfrac%7B6cm%20%5Ctimes%204cm%7D%7B2%7D%20%20%3D%2012cm)
Convert 7/8 and 4/5 into common denominators using 40; 28/40 and 32/40, multiply those to get 22.4. Divide 7 by 20 to get 0.35. Divide 22.4 by 0.35 for an end quotient of 64.
Answer:
and $475 deposited into the account on her birthdays by her 18th birthday.
Step-by-step explanation:
It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.
Initial term : ![a_1=50](https://tex.z-dn.net/?f=a_1%3D50)
On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.
Common difference : ![d=25](https://tex.z-dn.net/?f=d%3D25)
It forms an AP: 50,75,100,...
nth term of an AP is
![a_n=a_1+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29d)
Substitute
and
in the above formula.
![a_n=50+(n-1)25](https://tex.z-dn.net/?f=a_n%3D50%2B%28n-1%2925)
It represents the amount deposited into the account after n birthdays.
We need to find the amount by her 18th birthday.
Put n=18 in the above equation.
![a_{18}=50+(18-1)25](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B%2818-1%2925)
![a_{18}=50+(17)25](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B%2817%2925)
![a_{18}=50+425](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B425)
![a_{18}=475](https://tex.z-dn.net/?f=a_%7B18%7D%3D475)
Therefore, $475 deposited into the account on her birthdays by her 18th birthday.
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(1+-3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(-6+4)/2 = -2/2 = -1
(-1,-1)
