The question is incomplete:
17. Tonya's mother is 1.5 times as tall as Tonya was when she was 6. How tall is Tonya's mother? Use the correct number of significant digits.
The image with the information about Tonya's height is attached.
Answer:
68 in.
Step-by-step explanation:
According to the information given, you can write the following expression:
x=1.5y
x=Tonya's mother height
y= Tony's height when she was 6
Also, you know from the table that Tonya's height when she was 6 was 45 in. and you can replace this value in the formula:
x=1.5*45
x=67.5
Because of this, the answer is that Tonya's mother height is 68 in.
Answer:
The area of triangle for the given coordinates is 1.5
Step-by-step explanation:
Given coordinates of triangles as
A = (0,0)
B = (3,4)
C = (3,2)
So, The measure of length AB = a =
Or, a =
Or, a =
Or, a =
∴ a = 5 unit
Similarly
The measure of length BC = b =
Or, b =
Or, a =
Or, b =
∴ b = 2 unit
And
So, The measure of length CA = c =
Or, c =
Or, c =
Or, c =
∴ c = unit
Now, area of Triangle written as , from Heron's formula
A =
and s =
I.e s =
Or. s =
So, A =
Or, A =
Or, A = ×
∴ Area of triangle = 1.5
Hence The area of triangle for the given coordinates is 1.5 Answer
