Answer:
Option d. 1 in: 12 ft.
Step-by-step explanation:
A scale model of building is 2 inches tall. If the building is 24 feet tall then we have to find the scale of the model.
Since scale of the model is represented by the ratio of size of scale model and size of original building
= 
= 
Therefore, Scale of the model is 1 inch : 12 ft.
7 minutes= 2 minutes x 3.5
The squirrel burrowed 6 holes in 2 minutes.
To find how many holes the squirrel burrows in 7 minutes we multiply 6 x 3.5= 21.
Alternate method:
If the squirrel burrows 6 holes in 2 minutes that means he has burrowed 3 holes in 1 minute.
Multiply the number of holes burrowed in 1 minute by 7 to get 21.
Answer:
150
Step-by-step explanation:
The are is the sum of are of square and area of triangle.
A=A1+A2
A1=a*a=10*10=100
A2=a*h/2=10*10/2=50
A=100+50=150
• Move x to the other side
7y=21-3x
• Divide by 7
y = (21-3x)/7
Statements are all TRUE
sinA = 
and cosB =
cscA = 1/sinA = 1/(a/c) = 
and secB = 1/cosB = 1/(a/c) =
tanA = 
and cotB= 1/tanB = 1/ (b/a) =
