The area of a triangle is A = (b*h)/2:
(5 * 8)/2 = 20
Answer:
$6
Step-by-step explanation:
Divide 1.80 by 3, then multiply that answer by 10.
It’s the circle. Obviously
Multiply 4 by 10%.
10% ⇒ 0.1
4 × 0.1 = 0.4
Subtract 0.4 from 4.
4 - 0.4 = 3.6 (price with discount)
Multiply 3.6 by 6%.
6% ⇒ 0.06
3.6 × 0.06 = 0.216
Add 0.216 to 3.6.
0.216 + 3.6 = 3.816
Round 3.816 to the hundredths.
3.816 ⇒ 3.82 (price with tax)
The new price of toothbrushes is $3.82.
