Answer:
p=59.19°
Step-by-step explanation:
We first find the length BD
BD=√(6²+5²)=√61
Using Pythagorean theorem,we find p by:
cos(p°)=4/√61
p=cos^-1(4/√61)
p=59.19°
Answer:
Step-by-step explanation:
A = P + I
Putting values in the equation
4500 = 3750 + I
4500 / 3750 = I
1.2 = I
Answer:
Step-by-step explanation :
Let x be the number.
x × 8/100 =48
x =48 × 100/8
Now cut 48 by 8 and we get 6.
x = 6 ×100
x =600
So 600 is the required number.
Let's say the tv was 100$ . Reduced by 20% means the tv is now 100 - 20 = 80% of the original price.
0.8(100) = 80$
Reduced again; by 10% means that it is now 100-10 = 90% of the 80$
0.9(80) = 72$
sale price ÷ original price
72$ / 100$ = 0.72 which is 72% of the original price. Which is a mark down of:
100 - 72 = 28%
The new price is 28% lower than the original price.
