9(9n-5)
9=0 9n-5=0
9n=5
9/5 is the answer and 0 or 9(9n-5)
set up the ratios:
3/5 = x/15
Cross multiply:
45 = 5x
Divide both sides by 5:
X = 9
The model would be 9 inches long
Answer:
18.84
Step-by-step explanation:
Circumference = 2πd
where d = diameter
the shape given has a diameter of 6
to find the circumference we simply plug in the value of the diameter as well as π into the formula
formula : C = πd
π = 3.14 and d = 6
C = 3.14(6) = 18.84cm
Answer:
The supplement would be 62,
There is no complement
Step-by-step explanation:
A Supplementary angle equals 180 degrees
A complementary angle equals 90 degrees
Since mDEF= 128, which is greater than 90 degrees there is no complement to it.
To figure out the supplement of DEF you have to subtract 128 from 180.
180 - 128 = 62
Step-by-step explanation:
3 hour and 15 min = 3.25hr.
1 hour = 56 miles
=> 3.25 hours = 56 * 3.25 = 182 miles.
