Answer:
If 5 red shirts are added into the box, 7 : 8 is the new ratio.
Step-by-step explanation:
The number of red shirts = 16
Let the number of black shirts = k
Now as the ratio of Red Shirts : Black Shirt = 2 : 3
By RATIO OF PROPORTIONALITY:
⇒
or, 
Hence, the number of Black Shirts in the Store = 24
Now, new number pf red shirts = 16 + 5 = 21
So, by the proportionality again, ratio is

Hence, the new ratio of Red shirts : Black Shirts = 7 : 8
Answer:
g(4) = 157
Step-by-step explanation:
g(x) = 8x^2 + 9x - 7
Let x =4
g(4) = 8 * 4^2 +9*4 -7
=8*16 +36 - 7
=128+36-7
=157
For this case what is asked is to find the area of the window.
The area of the window in this case is a rectangle.
Therefore, the area is given by:
A = (18 * (1/12)) * (2)
A = 3 feet ^ 2
Answer:
the window is:
A = 3 feet ^ 2
Answer:
The length of the diagonal is 13.90 inches
Step-by-step explanation:
This question can be remolded as calculating the length of the diagonal of a rectangle with dimensions 11 inches by 8.5 inches.
The diagonal refers to that length that runs from one inner edge of the rectangle to the other inner edge of the rectangle.
To calculate this length, we shall be making use of the Pythagoras’ theorem
Please check attachment for the kind of figure i’m trying to paint.
Let’s call the diagonal D
Using the Pythagoras’ theorem,
D^2 = 11^2 + 8.5^2
D^2 = 121 + 72.25
D^2 = 193.25
D = √193.25
D = 13.90 inches
