Answer:
Step-by-step explanation:
Using the formula
Initial -final/initial =%/100
89-72/89 =%/100
17/89 =%/100
Making %subject of the formula
% =17*100/89
So % =1700/89
%= 19.101
Therefore rounding off the answer we have
X=19%
Answer:
Angle M = 61°
Angle N = 87°
Step-by-step explanation:
in the given problem :-
the measure of exterior angle of a triangle is equal to the sum of measures of two opposite interior angles of the triangle .
so,
=》4y + 9° + 6y + 9° = 148°
=》10y + 18° = 148°
=》10y = 148° - 18°
=》10y = 130°
=》y = 130° / 10
=》y = 13°
so,
angle M = 4y + 9 = (4 × 13) + 9 = 61°
angle N = 6y + 9 = (6 × 13) + 9 = 87°
The answer is distribute property
Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
