Correct answer is B
10/15=.666
This is RW divided by RT
Now you have to use the scale factor. Multiply by 18 to get WV
18 x 0.666 = 12
Good Luck Thnks for brainiest :)
Circumference = 2xpi x r
=2 x 3 x 5
=6 x 5
=30
Answer:
18pi units is the circumference
81pi units² is the area
Step-by-step explanation:
Radius² = (-2-7)² + (2-2)² = 9²
Radius = 9
Circumference = 2pi×r
= 18pi
Area = pi × r²
= 81pi
Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.
