Answer:
1r
Step-by-step explanation:
(5r-4)(2r-6r+4)
1(5r-4)+1(2r-6r+4)
5r-4+2r-6r+4
5r+2r-6=1r
1r-4+4
-4+4=0
1r
Tina should make 31 inch tall model to replicate 155 feet tall monument.
Step-by-step explanation:
This problem can be solved by direct unitary methods easily-
Firstly, Scale is the ratio of the dimension of the original substance to the dimension of a model
Scale= original dimension/ model dimension
Model is the miniaturised representation of a substance.
The monument is 155 feet tall
Tina replicates it with a scale 1inch: 5 feet
Thus, this means that Tina would need 155*1/5 = 31 inch tall model to replicate the complete length of the monument.
Hence Tina needs to make 31-inch tall model.
Answer: -0.5c
Step-by-step explanation: multiply -2.5 by 1/5 (0.2) and you get -0/5
Answer:
≈119.3
Step-by-step explanation:
The area for circumference is as follows:

The above equations mean the same thing, because the diameter is just 2 times the radius.
Anyhow, we insert this value into the equation...

This rounds to:
≈119.3
Answer:
x + y = 64
x = y + 14
Step-by-step explanation:
Given:
Total number of student = 64
x = number of students in filmmaking club
y = number of students in yearbook club.
Computation:
So,
x + y = 64
And,
x = y + 14
So
Number of students in yearbook club = 25
Number of students in filmmaking club = 39
