Answer:
Step-by-step explanation:
20% = 20/100 = 0.2
The amount you need to pay for a T shirt is
Cost = original amount(100% - 20%)
Original amount = 18
100% - 20% = 80%
80% = 80 / 100 = 0.8
What this means is that you will pay 80% of the original cost.
Cost = 18*0.8
Cost = $14.40
Part B
Cost = 0.8 * x
Part C
Selling price = 0.8*Original Cost
Selling price = 18
18 = 0.8 * x
18/0.8 = x
x = 22.5
The original price was $22.50
Answer:
<u>67 m/s</u>
Step-by-step explanation:
Formula for range :
- u = initial velocity
- θ = angle of launch
- g = gravitational acceleration
Solving with the given values :
- 400 = u² x sin60° / 9.8
- u² x √3/2 = 3920
- u² = 7840/√3
- u² = 4526.4
- u = <u>67 m/s</u> (approximately)
Answer:
you save $90 each week your brother save $71 each week.
so your answer would be your brother saves $19 less than you each week
35kg - a mass of sugar syrup
30% of 35kg it's a mass of sugar
30% = 30 : 100 = 0.3
30% of 35kg = 0.3 · 35kg = 10.5kg - a mass of sugar
Add xkg water. Then we have (35 + x)kg of sugar syrup and still 10.5kg of sugar.
10.5kg is 25% of (35 + x)kg .
(35 + x) -- 100%
10.5 -- 25% <em>multiply both sides by 4</em>
42 -- 100%
Therefore we have the equation:
35 + x = 42 <em>subtract 35 from both sides</em>
x = 7
<h3>Answer: We should add 7kg of water.</h3>
