Percent means parts out of 100, remember that
12% off
12% off means 100%-12%=88%
find 88% of that
then take 3% and addd that
3% off of 100=100+3=103% of that
then
so original price=p
find 88% of that then 103% of that
p*0.88*1.03=final cost
p*0.9064=final cost
0.9064p=final cost
The answer is 18. You add 5 to both sides of the equation. the 5 cancels out. You are left with 2/3x=12. Then you divide 12 by 2/3 to get x. 12 divided by 2/3 is 18
Answer:55.6%
Step-by-step explanation:
45-70= -25
-25/45 = 0.555
=55.6
Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
= , that is
= ( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = ≈ 78.55 cm ( to 2 dec. places )
Answer:
x and y = 5√2.
Step-by-step explanation:
This is a 45:45:90 triangle so length of x = length of y.
In this triangle the ratio of the sides is 1:1:√2
Finding length of x and y:
1/√2 = x/10
√2x = 10
x = 10/√2
= 10√2/2
= 5√2.
