Answer:
197 dimes and 1 nickel
Step-by-step explanation:
19x100=1900÷10=190
7 more from 70 cents and 1 nickel from 5 cents
Answer:
4/5 of an hour
Step-by-step explanation:
3/10 of an hour (60 minutes) equals 18 minutes
3/4 of 5 km equals 3.75 km
therefore, you can create a ratio of minutes over km equals min over km
let 't' = time
18/3.75 = t/10
cross-multiply to get this equation:
3.75t = 180
divide each side by 3.75 to get:
t = 48 minutes
48 minutes out of 60 minutes equals 4/5 of one hour
Answer:
Step-by-step explanation:
The interior angle of a polygon is given by
(n-2)×180
or for regular polygon n × each interior angle.
Therefore since it is a regular polygon
Given than interior angle is 144
Then,
(n-2)×180=n× interior angle
180n-360=144n
180n-144n=360
36n=360
Then, n=360/36
n=10
Then the polygon has 10_sides which is a decagon.
X=-4
How I did it :
12 - 3x = -6x
Add 3 x to both sides:
12 = -3x
Then divide both sides by -3:
-4 = x
And just switch it around
Answer:
43
Step-by-step explanation:
on the shape to the right angle k looks similar to angle p and we know angle p is accute making it less than 90
